overclocking and athlon 600Mhz?

[Slicers]

I've got a MP-7VIP motherboard
athlon 600Mhz
Win 98 SE
GeForce DDR
15Gb hard drive
Creative sound card
Please try to make it simple 'cos I only started overclocking

To overclock a 600mhz Slot A Athlon CPU you will need the Gold Finger Device available from many sources. The price of these range from $35-70 depending on who manufactured it and where you obtained it from. One of the better units is the Ninja Micro one. You also have to open the plastic casing around the CPU. After all is said and done, you might want to spend $190 and get a new CPU and Motherboard. A Duron 700 can be found for around $60 and a good board for $130 and you could reach speeds of 1Ghz, but with the Athlon 600 you will be limited to around 750mhz on average. A Duron or Tbird will outperform a Slot A Athlon around 15% at the same clock speeds as well. It's your choice and money obviously, but if $200 is a reasonable amount to spend on an upgrade, do it!!!

Duron generally slower than Athlon Classic.

Actually a Duron processor is generally about 3% slower than an equivalently clocked Classic Athlon. Then again, because you can overclock Durons better and easier, you still will probably end up with better performance out of it.

My question regarding overclocking Athlon Classics is whether the cache speed is increased when you adjust the processor's speed? If not, you may not end up with any performance increase at all. If so, it might be just one more thing adding to the instability of the overclock. Overall, not a very comforting thought.

The old Athlons with external cache have the speed of the cache set to 1/2 the speed of the CPU. This is not fixed, but dynamic, so it you have a 600mhz cpu the cache runs at 300mhz, if you overclock the cpu to 700mhzm than the cache MUST run at 350mhz, at 800mhz cpu clock the cache MUST run at 400mhz, this is the main contributing limiter to the old Athlon as the cache could simply not take the speed, otherwise AMD would have put 400 and 500mhz SRAM 2nd level cache in them, but one they past 700 or 750mhz the cache divider was set to 1/3 the speed of the CPU. This is the instability of the old Athlon line and the crippler that did not allow the old Athlon to really enjoy the speed increases as much as they should have. Kinda feel bad for AMD, if they could have gotten the Tbird to the market 6 months earlier with the internal cache, Intel would have in no way enjoyed the sucess of the Pentium III as much as they had.

Is it possible to overclock an athlon 700a to 1.2g using a GFD and An Asus K7V-RM mobo combo?
