Although Athlon has already been released, the moment is always not small, but unfortunately I have never seen a real Athlon system, although countless evaluation reports, whether floating point operations or 3D performance is obviously Athlon more In order to be advantageous, but it seems that all the crowders are more willing to choose PIII, so every time I Athlon is in Zhongguancun's counter ... For this kind of admiration to Athlon, I have always been good for AMD (of course also There is a more important reason), in the case of the original PII 400 SUPER PI, I can't bear it in the case, I resolutely rushed to Zhongguancun bought a set of Athlon 600 英 EP-7KXA system, pay After the payment, the boss took a piece of AMD original fan, I won't wait for me, three times, I gave it up, my darkness is not good, I know, the fan is easy to get difficult, once it is installed, I want to remove it, I will not care about it ... I am busy saying that the boss said: "I want to learn how to install the CPU fan, please take it again.", "Row!" The boss is very refreshing. However, the fan is extremely fast, what tools are used or threaded, and finally, I don't have me. As the boss roars a metal strip of the fan, the metal strip of the fan is broken, and a new fan is pulled out with a new fan. Say "You go back to install it", you are working together! Why not install a fan? Just because this Athlon is also responsible for an important mission, this is the most important reason I bought it - overclocking! Holding the board and the poor Athlon, returning to the home, three down five in the second set of motherboard power CPU memory strip display graphics card, short connected POWER jumper, self-test After the sound, "Athlon 600 (6 * 100)" appeared in front of his eyes, entered the CMOS, found that the latest K7 motherboard of this 英 is really great, the outer frequency can be set from 83MHz to 115MHz, Although the CPU core voltage needs to be adjusted on the motherboard. As a motherboard in the market, it is very good to do this. Because I didn't add a fan, I closed the power after I changed the CMOS, I closed the power, no more than 2 minutes before and after, even when I took the CPU, the temperature still made me bold, and I found a large amount of Athlon's heat. . To overclock at Athlon, nothing more than two roads can be taken: superfluence or ultrafire frequency. It is undeniable that as long as the motherboard supports, the ultra-frequency is effective method, and with the improvement of the external frequency, the performance of the entire system will increase significantly. However, the maximum weakness of superfrequency is the instability of other peripheral equipment, which is fatal. I am going to go, actually is another road - super frequency. Ultra-multiplier faces the CPU lock, before Athlon, most of the CPUs are not unlocked, but due to different positioning, AMD is launched after Athlon, and the intel is locked, which gives the overclock. It has been very difficult, but some hardware sites that have been so fast have launched an Athlon breaking method. The most famous of course is Tom's Hardware Guide. All Athlon modified data from this "heartbeat" is from this. Site. To give Athlon surgery, the first thing to do is of course opened its housing.
A phrand in a package is actually divided into three parts: the top is a plastic case, which is part of the AMD logo; it is a heat dissipated metal plate; the plastic shell and metal plate are the protagonist of this surgery - - Circuit board with an Athlon processor and two L2 Cache. As shown in Figure 1. Figure 1 ATHLON package structure has eight metal rods on the metal plate on the reverse surface, and four of the angles are fixed metal plates and the plastic shell above, while four elastic metal sheets will close the chip board. Tightened on the heat dissipation metal plate. First, I want to open the front plastic shell. I used a flat number, plugged into the metal plate and the plastic shell, carefully shake it near the four metal rods on the corner, remember some information, the bottom left corner Because of the special treatment, it is particularly difficult to open. If it is unlikely, with the "啪" three sounds, the metal pole on the other three corners is loose, the metal pole in the lower left corner is still a silk, and finally The metal plate and the plastic shell have changed the shape to pine this metal pole. After removing the plastic shell, the reverse surface of the circuit board is exposed, two elastic metal sheets press the chip board on the metal plate, and remove the two elastic metal sheets to separate the chip board and the heat dissipation metal plate. To be much easier, I use a small caliber cross screwdriver and the sharp pliers, soon remove the elastic metal sheet, carefully turn the chip board over, I saw a exciting picture: The "K7 700" is written on the chip of the K7, not the "K7 600" should be based. I quickly realized that this is the technique of "downgrade sales" that Intel has also used, which should be said that chip manufacturers have no need to consider, but no matter how, thank AMD to send me Such a gift. I remember that a AMD senior official has said: "The K7 650, 700 can work firmly under 800MHz." It seems that there is a cause. Next, we must formal start surgery, my goal is Athlon750! According to the data of Tom's Hardware Guide, Athlon's multiplier determines the arrangement of the three sets of patch resistors, which are R155, R156, R157, R155, R156, R157, R158, R121, R122, R123, R124 and R3, R4, respectively. R5, R6, which are shown in Figures 2, 3, and 4, respectively. 2 R155, R156, R157, R158 Position Figures 3 R3, R4, R5, R6 Position Figures 4 R3, R4, R5, R6 Figure 5 R155, R156, R157, R158 and R3, R4, R5, R6 Combination relationships Figures 6 R121, R122, R123, R124 Combined relationships Next, the three sets of patch resistors in Figures 5 and 6 are arranged in different frequencies, which determine the part that needs to be changed, specifically from 600 The 750 is also need to remove the R155, R158, R4, R121, R122, and R124 six resistors, and the soldered R156, R157, R3, R5, R6 and R123 six resistors, saying that it is easy to do, this sticker The plate resistance is not even one-third of the rice particles, what is easy to use electric soldering iron ... but in any case, for the 350MHz myth, no matter what difficulties can't stop me, with specially purchased ultra-small caliber tip and bend The head scorpion, I hardly removed the six resistors and soldered six resistors. Everything seems to be smooth, this Athlon completed the bones from 600 to 750, but when I put this Athlon 750 into the previous one When the slimming system is in the system, the display does not light.
Suspected that the CPU did not plug, but also tried several displays or did not respond, no self-evaluation CPU is not hot, I was soft, I went to a cold sweat, I know this value of nearly two thousand yuan CPU I haven't hot it, I will not be scrapped here, I must have a mistake in the process of operation, I have checked the three sets of 12 patch resistors over and again, and the position is definitely no mistake, but there will be What's the problem? Is it ... I took out the multimeter, 12 resistances were tested, and I found that the two resistors of R156 and R157 did not pass. It was obviously burned. These two resistors were soldered, and they were not enough to start the courage. It is very likely because the heating time has caused these two resistors to be burned, so I have already prepared a lot of this 0603 package 1K ohm 102 patch resistor. This action is replaced with two new resistance. Be careful to remove the residual solder, check all other resistors, plug in CPU again, boot - with self-evaluation sound, the display will illuminate "Athlon 750 (7.5 * 100)", finally successfully ! I suddenly got up from the seat, but I haven't waited for me. The system is dead, or the phenomenon of the typical overclocking failure, is Athlon700 less than 750? This is an impossible thing, suddenly, I realized that only a chip board in the CPU slot, I even even sleeve, not to improve the fan, in this In the case, in the overclocking state, Athlon's ultra-large fever, no monster, think of this step, I put a thick layer of thermally conductive silicone and the cached surface on the chip board and the cache on the chip board. The film is equipped with a heat dissipation metal plate, as for the plastic shell, not installed in consideration of heat dissipation. The finally installed CPU fan must also be selected, the original AMD K7 special fan heat sink is big enough, but only one fan, so I changed a heat sink with high-power double-fans, and used thermal silica gel Stitching onto the heat dissipation metal plate. After everything is ready, insert the CPU to connect the hard disk, boot, self-test, enter Win98 ... ok everything is normal, run WCPUID, Athlon 600 really reboot into Athlon 750! Next is the 3DMark99 test, the result of the CPU 3DMarks has been more than two thousand points, it seems that 3D Now! Enhanced is not a wave of emblem. The final stability test is of course relying on the Need for Speed 4, and a few cars are soaked to touch the CPU. The temperature is only warm, this time the "core jump" is great. People say that overclocking is "core jump", I said that overclocking is "heartbeat", especially when you are superior, the high-end CPU that is one or two thousand yuan, just remember when I use the electric iron to facing the Athlon At 600, I thought "I don't know how my core can jump, my heart can be jumped soon." After this time I "my heart", Athlon successfully "core jump", in fact, no matter "Heartbeat" or "core jump", it feels very exciting, great.
