I have this Japanese site, but the text won't show, even in Japanese mode. Can anyone run a translation for me,? http://www.echna.ne.jp/~kim/Kim4/Link5.html
http://dreamcast.onlineconsoles.com/phpBB2/viewtopic.php?t=2906 contains a lot of inks to the same info. one claims to be a translation of the one you posted.

Bloody hell, that was fast I'll just copy and past it here. -------------------------------------------------------------------------------- Dreamcast Clock rise -------------------------------------------------------------------------------- It is a house. "SEGARARI 2 is made!" It is glad and they are software and Dreamcast. (Following DC) を -- having purchased simultaneously was a thing in February, 99 of soft sale すぐ Although it was playing about three months, it 飽きed bored unawares on the way, and it carried out, and it was and was buried into the rubbish of the room till recently. To the inside which is hearing a network friend's talk although introduction with a magazine was seen and it was worrisome MURAMURA Having come "Metropolitan quantity battle 2" . (Smile) One month has already passed since sale, there is also poverty, and the used article was got last month. When it began to have done, the screen was also beautiful and was converted. Racing controller with a put pedal It used and was running every night. (^^ゞ. However, that it is worrisome came out as it did. 1. During a play, when reading course data from CD, it will stop for a moment. 2. A thing with hard insufficient capability, and thing with heavy software Top omission occurs. It carries out. 2. is a problem although 1. is an unavoidable thing in the relation of the amount of memory loading. Brilliant top omission when the number of the cars of a screen in a replay screen becomes 3-4 or more sets is a scene with many pillars, when there is much number of a car or it passes through the bottom of a bridge also in a play, although it can bear somehow. (Scene with many objects) It is regrettable that come out and top omission occurs suddenly. (Timing not suiting.) Crashing into a pillar is .... repeatedly. <- it is only the lower part. Every place see also at a soft demonstration play. Although various methods, such as video card exchange, CPU exchange, a memory addition, and HDD reinforcement, can do these measures in the case of a personal computer, in DC, it is finished-goods treatment. (Consumer machine) since -- strengthening is impossible My DC First stage type It comes out. "Is it a change?" Although considered, condition was the same also at an acquaintance's DC purchased recently. (I purchased.) First stage type Playstation は and a minor change are those with several times, and a new model. (It is not PS2) は処理 speed was improving. PS-ONE is unknown. In a smooth play sake "There is only a clock rise!" Although considered, it is not found even if it investigates in a network. Although I thought ... and there was uneasiness when becoming, it decided on this reconstruction. Since trial and error went well at last variously, it reports. (An introduction is a seed too long slightly.) (^^ゞ. -------------------------------------------------------------------------------- ***************************** * A maker guarantee is lost when reconstruction below * is performed. ** * * It cannot have responsibility, when not going by reconstruction well again. ** ***************************** -------------------------------------------------------------------------------- It is a photograph before decomposition. (It is in the carp state on a cutting board.) (Smile) It is at a frequency counter that it is in 左奥. Measurement of PLL-IC or a terminal and a check can be performed. It decomposes at a stretch. Because those who cannot do so far give up and read, they need to do ... (by way of precaution) Since it can decompose independently for every part with CD-ROM, a power supply, a main board, and a modem interface board, it is maintenance nature. (Decomposition nature and reconstruction nature ?) は is good. It is the rise of DC board. It is almost the same although stop-motion photography was variously obtained in the network, and a layout changes a little with manufacture time. A central large tip is video. Power VR2 A little small tip of the right-hand side CPU SH-4 . When the power supply base of DC is also investigated, it is 12 V.5 V.3.3V and the same level as a personal computer. (Although there are no 3.3V in the power supply of a personal computer, it is made on a mother board.) It is the spec. of DC as a result of looking for many things in a network. Here It comes out and they are the detailed data of SH-4. Here It can try to come out. (The data of SH-4 are PDF files.) They are all. 750 pages! since -- cautions are required when printing I have done all page printings in the company, without thinking deeply. When it has noticed ... (+_+)) Data detailed for general seem not to release them, although various video tips searched. if it refers to the spec. of DC and PDF data are seen -- this -- SH-4 33.33Mhz It is の入力 and is internal magnification. 6 times 200Mhz It seems that it is coming out and operating. Magnification is an input like fixation. 33.33Mhz を上げれば will be good. (If data are seen, there is the mode which drops a clock during operation.) Is Windows CE etc. an object for mobile inclusion? (Although the clock rise also of the voice relation has been carried out in the clock rise of Playstation, since the timer related clock is built in the inside in another circuit, in the case of SH-4, it is likely to become somehow.) Instantly, it is on a substrate. 33.33Mhz It is not found although the の crystal was looked for. A package is QFP. (Type out of which the pin has come to four sides of tips) Then, there is nothing and it is BGA. (The pin has not come out and it is connected on a substrate and the tip undersurface) It is の and is an external clock. Input pin を探す's was difficult. Although watched for a while, if it often sees, it is the same as a personal computer case. PLL-IC を使っています. This is a problem. It is the rise of an PLL-IC part. If a frequency counter investigates 13.5Mhz The signal sent with the の crystal is 分周(ed) and amplified. 33.33Mhz 54.00Mhz が作られています. (A mere crystal change) 33.33Mhz 54.00Mhz Both It interlocks and frequency changes. If it is intelligibly made a figure, it will become like this. others -- although investigated in the network about the detailed thing, I do not understand It seems to be a custom IC. If it understands so far and will be the more detailed one, I think whether it is easy. It is the crystal oscillator group prepared this time. (It is the best if there is an oscillator which can carry out variable [ of the frequency ].) It has increased, while playing many things. (Smile) ..., such as 等 removed from what purchased newly, and the junk article In order to gather processing speed, such as a game, generally in the case of a personal computer ? The frequency of CPU is raised. ? The frequency of a video tip is raised. ? Memory-related access speed is gathered. ? は -- simple -- it is lucid ? It is effective, although it is alike, and it is related and is not known unexpectedly. ? は. It is alike, and unlike a personal computer, DC is not easy although related. (? It will be alike, and will interlock and go up. On a momentary target PLL-IC Carry out a の足 raising and another clock is inputted. PLL-IC part は -- just under a power supply part, it becomes exactly Since the power supply desorption for every test is troublesome, extraordinary code connection is made from a substrate connector. A test becomes quite easy now. 54.00Mhz Instead of [ of the clock considered to be の video relation ], 60Mhz It を供給. Although it seems that it is moving somehow if a power supply is switched on, a screen will flow. (A sound is normal) It seems that the frequency of a video signal has also interlocked and gone up too. Since TV cannot perform frequency flattery like a personal computer monitor, this method is abandonment. (It may be reflected if it connects with a personal computer monitor via option VGA-BOX.) To the next 33.33Mhz On a の CPU input clock 36Mhz を入力. (36.00Mhz x 6 =) 216Mhz Operation It seems that it moves by this state satisfactory for the time being. (A sound is also normal) The two methods of a clock rise are considered as a result of a preliminary experiment. A Intercept 33.33Mhz and supply a clock to direct CPU from another oscillator. B Change the clock for CPU indirectly by PLL-IC crystal change. (54.00Mhz is intercepted and it is 54.00Mhz(es) supply to the video relation from an oscillator) This time, the number of parts is simple few. It decided to take the method of A. It is a problem here. The clock supplied to CPU How much is it made? . In the case of a personal computer, it is made into the clock which raised to the limit and gave the margin for a while after the check. In the case of DC Processing Heavy software is smooth. Since it will be O.K. if it is alike and moves then, it is not necessary to move by force. Although new software requires high spec. rapidly in the case of a personal computer, in DC, it is. Hard capability is fixed. . (Since too heavy software does not become a game, a software maker cannot ship, adjusts and makes it the grade which is convenient into a play.) If appearance is modest even if the screen of a motion is good, although a screen is beautiful, and a software maker is the translation which takes pains over adjustment, since that a motion is smooth is the demand which conflicts also in the world of when A rival machine and a rival maker Since it is alike and a market share is taken, the present condition is having closed its eyes a little and having put on the market. This time, "Metropolitan quantity battle 2" The level which moves without が stress is a target. In order to determine a clock PLL-IC の pin leg raising processing is fixed. The leg raising was carried out. A code is attached to the pin of PLL-IC, and the pattern of a substrate. Since uneasiness is in intensity only with soldering Hot bond It comes out and a code is fixed. (A general code) since a twist line is dangerous -- surely Single heart code を使います. In order to decide a clock, CD-ROM is connected and a real operation check is performed. under operation -- CD-ROM -- beyond anticipation High rotation Since it carries out, cautions are required. Since replay with heavy processing was not SAVE(ed) in a visual memory, anyone checks it at the demonstration play immediately after the power supply injection which is possible ? check. -------------------------------------------------------------------------------- -> -> It is a scene immediately after the 1st demonstration start. (After [ of demonstration start / 8 seconds ] -) FD in a straight line It is the scene which carries out an after [ contact ] dash (back SUPURA) to NSX, and goes. When there is much number of a screen, top omission has occurred. Depiction of FD is smooth if the number decreases. -> -> It is a scene immediately after the 2nd demonstration start. (After [ of demonstration start / 8.5 seconds ] -) Although a taxi is unsteady in front of red R32 GTR and blue R-34 GTR (back in PURESSA) and it passes through the left, on the screen out of which the taxi has come, there is top omission, and if a taxi disappears and it decreases the number of sets from a screen, processing will become smooth. The above is Normal. 33. 33MhzX6=200Mhz It is operation. The scene same besides this (Portion [ scene / which decreases from the scene whose number of a car increases ] of relation) が各所 sees. -------------------------------------------------------------------------------- now 36.00Mhz It を供給 and the same scene is seen. (36.00Mhzx6=) 216Mhz although both of the scenes are considerably smooth -- the 2nd demonstration scene -- to a slight degree -- と -- it is just going to say It continues. 40.00Mhz It を接続. (40.00Mhzx6=) 240Mhz With this clock, it is smooth and does not those[ with a problem ]-ま at all. It seems (video is seen.). Exaggerated ? completely The self-satisfied world It was alike and had entered. If it is watching then be -- れ On a screen A noise begins to enter. It has stopped. It is considerably heating, although a power supply is shut off, CD-ROM is removed and a heat sink is touched. It seems that the memory stopped following and generation of heat increased with the exaggerated clock. It once cools, and a power supply is switched on and checked again. If it is a bow, looking at a demonstration, a noise will begin to enter too. Although a cooling spray cools a memory, a noise does not decrease. When CPU was cooled, the noise stopped. How Cooling If it carries out 240Mhz It seems that but it is OK. It is a measure here. In the case of a personal computer, it is at the time of such a condition. (1) Drop some clocks. (2) Strengthen cooling. (3) Raise the voltage of CPU. (About 10%) The above is considered as a measure. (1) is made into the last means. Reconstruction of a power supply part is required for (3), and since there is a possibility of breaking sushi and CPU, it is made to take the measures of (2). In DC, it is the heat of CPU and a video tip. Heat sink -> heat pipe -> main part exhaust port (?) heat sink It is transmitted in this order and forcible cooling is carried out by the fan. If original, the heat sink is being half-fixed to each tip with the heat conduction sheet. This time, this sheet is removed. Direct A heat sink is attached. Under the present circumstances, it is heat conduction in order to gather conduction efficiency. Silicone grease を -- it applies thinly (In the world of a personal computer, it is common sense.) Although heat conduction improves now, it is between a heat sink and a fan unit. Crevice A tape is carried out by がある's, a gap is filled with a hot bond, and the flow of air is made smooth. (Crevice condition can be checked with the upper photograph.) Although he wants to attach an individual larger fin, it does not fit in a main part. (+_+) I want to attach a directly large fan to CPU originally. Next, the fin and the case lower part of an exhaust port exit are extracted. the mark is put and it comes to be alike of appearance in the least as deleting drastically by RYUTA (^^ゞ. Natural Exhaust gas side Since it is a direction omission in foolish り, it is the back of a main part. Inhalation-of-air side ? also removed the fin. (They are the foundations of engine tuning of a car.) (Smile) In order to confirm the effect of the measure against cooling, the main part of a rose rose is pumped up at once. Here, it is problem generating. the heat sink of each tip is lacked, and although it is coming out and fixing, it is impossible for the shield board of a substrate to break, and for an about 2mm crevice to fix it by the ability doing, as a result of having removed the heat conduction sheet Although it worried just for a moment A thicker washer is pasted up with a hot bond. It carries out and enables it to fix. In order to see the effect of the measure against heat dissipation, it tests by including all in a case. It is next time although it was made to operate like 2 time. 240Mhz Operation is not those[ with a problem ]-ま(ed), either. (^^)/ -------------------------------------------------------------------------------- It is inclusion of the last. In problem generating, something is the normal mode. (200Mhz) A switch is attached so that it can be alike and can change. They are the parts which the upper left attaches. (Although a trial-and-error method was applied to many things, it is only this part after all.) Pin assignment of a clock oscillator is as the upper right. (This type is 4 pin specification.) A substrate is processed, it wires and a wire is fixed to the chassis of CD-ROM. Attachment is performed by actual thing あわせ. Although it thought that a switch could be operated from this outside of the body The clock change under operation is under incorrect operation. . therefore, not usually visible -- as -- It enabled it to change, where the lid of CD-ROM is opened. (Maniac liking ?) It is this. Completion . Reggae (Race game) など When top omission occurs, 240Mhz Operation It is usually a game, such as RPG. (It is a strange way of speaking) It は and is normal. 200Mhz operation A change is possible. Maniac DC ? It が完成(ed). Now, it is the rest. "Metropolitan quantity battle 2" の最終 ending is only seen. (This is difficult!? (smile)) -------------------------------------------------------------------------------- Addition It seems that there is no big problem although this talk was popular and also gave an acquaintance's DC. Supposing there is a problem, the writing to a visual memory A little unstable It is the point of coming to be alike. (Reading is OKed!) (Although a part of cause which the access speed to a visual memory goes up, and liquid crystal display becomes amusing again, it is uninfluential into a play.) The visual memory which I purchased this problem Initial type It seems that it carries, and it is satisfactory what is put on the market recently although it may be. (A display is ... although it is amusing too.) Others Although reconstruction of DC was also carried out, even if it does not take the measures against heat dissipation in a different lot 240Mhz operation is satisfactory. There is also a thing and 240Mhz operation It will not be stabilized however it may do. It seems that there is a thing and there is variation. (The unstable thing pressed down the clock.) but -- from the first 200Mhz operation specification since -- although it is unavoidable ... On a general target The margin of operation is taken and, as for CPU, the exaggerated clock of a grade is satisfactory in many cases 10 to 15%. I used with the personal computer before. CPU Pentium 133Mhz -> 180Mhz MMX Pentium 233Mhz -> 290Mhz It came out and moved satisfactory. (400 or more Mhz(es) of K6-2 400Mhz(es) used now are not stabilized.) (+_+)) This reconstruction DC is the relation which deleted the margin. Generation of heat Problem It comes out and is my room without the air conditioner of midsummer. 240Mhz operation は Probably Probably, it will be impossible (smile)! ( with it being reverse, if voltage and the measure against cooling are strengthened, I will think that it moves by the high clock further ... probably.) -------------------------------------------------------------------------------- It returns.
Yakumo now if you feed that into Japanese and retranslated into English I'm sure that will be fun... :-D
I had a link to a site that had a real English translation, but I think it was missing a few important bits.
http://www.ucm.cjb.net/ On the left hand side, it says "Dreamcast Overclock Guide." Click it, and you've got it, all in [real] English. :smt045 That's a full English translation of the Overclocking guide. It's not nearly as hard as it was originally implied to be. Though you will need extra cooling--that isn't too difficult. You'll need an oscilator to get it above 200 MHZ (normal clock). :smt023
