I had long since been running my xp 2400 with a 166MHz fsb (166X13) in sync with my Twinmos PC2700 CAS 2.0 (2X256Mb) on my NF7-S.About a week ago I decided to try to push the fsb as far as possible at 1:1 fsb/memory.I first went to 176, then 181, then 186 with no problems in 3dmark03 or in short term prime95 tests.So, I decided 'f**k it' and just went straight for 200MHz 1:1, 10.5 multiplier.It worked fine!This is without changing the memory timings at all (7-3-3-2) and without increasing VDimm!
Gradually i pushed it up to 208FSB (memory still at 1:1 7-3-3-2).I have run 3dmark03 on it countless times and prime95 tested it for about 48 hours straight without issue.
However,weird things have begun happen in the last day or so.Now, when i leave my computer on for a long period of time, sometimes after a few hours or so things start to slow down.Sandra reports a cut in memory bandwidth when benched and the cpu usage is constantly at 100% for some reason, even if no programs are open.It's all very odd though because if i restart, everything goes back to normal (including the memory bandwidth and cpu usage).It can also still benchmark fine in both 3dmark03 and prime 95.
I don't understand quite what could have happened to make me lose the stability i had(like i said, i ran prime95 for up to 48 hours!).What could be the issue?My NF7-S is only a V1.0, so is not officially 200/400FSB compliant- should i perhaps increase the chipset voltage?
I would be very grateful for any help at all.
My relevant system specs are:
XP 2400 @ 208 X 10.5 with 1.775VCore
2X256MB Twinmos PC2700 1:1 (i.e.208DDR) with 2.6VDimm
Abit NF7-S v.1.0 (with newest bios)
Seagate Barracuda 7200.7 SATA 80GB
Volcano 7+ HSF
no matter how hard you try, you can't polish a turd. :]
