R U sure you soldered the L2 in the right places? my athy 500 550 core does firstname.lastname@example.orgV and my athy 600 600 core does email@example.comV. and my athy 750@firstname.lastname@example.orgV.
i would recheck your L2 the two slower ones of mine do there speeds at 1/2 the 1035 is at 2/4 maybe 1/3 if i wana go higher.
so keep your l2 where it is and boot at say 600. check to make sure it's running at 2/5 or 1/3 i would use 2/5.
if all eles fail try using a GFD if your soldering. i soldered mine but well. maybe i was lucky.

+ resistor (circuiet lo)
- no resistor (circuit high)
I have checked every resistor "thousend" times, and I have begin to think that Tom`s Athlon Classic overclocking guide is wrong.
In windows I check L2 state and WCPUID detetcs 1/3 L2, and then if I need faster L2 I can speedup L2 with h-odas utility, and 3,6ns and 3.3ns chips work great @ 350MHZ or 1/2 L2, and I can mesure that in QIII and memory benchmarks.
So I think L2 is not the problem and I think PSU is not the problem, atleast it should not be problem with K75 CPU (0.18 micron).
The worst system is not the one that has slowest QIII frame rate, but one that not works corectly.
