Question about lower speed Athlons with higher cores

Hello,

I have a Athlon marked as a 700MHz cpu but it has a wonder 900MHz core (week 26). I was wondering about the cache. It says on the chips 3.6 or 3.8ns (can't remember if its a .6 or .8 right now) by Samsung. Are the chips marked wrong or do all 900/1000MHz Athlons have that slow of cache? Also, the highest I can get it to overclock is 1062MHz, I can get it at 1074 using SoftFSB but windows gives me a BSOD after a few mins. Could this be a heat problem or the cache being forced to run faster then what it can handle even with it set to 1/3?

If you run 3.6ns cache at 1062 1/3 divisor.

here's the maths. 1062/3 = 354MHz cache speed is ruuning at

1000/3.6 = 277.7MHz cache is designed for.

So the cache is speed rated to run at 277MHz stable, when you are running the cpu at 1062 on a 1/3 divisor the cache is running at 354MHz well over spec. So your cache is definatley holding you back.

Try disabling the cache in the bios to see how fast the core can go.

The 700 has 2.9 ns or 2.8 ns cache. If you can run at over 1 gig- be happy, mine will "only" do 927 mhz stable
