Low Gainward Ti4200 OC results and problem

[Rakshasa]

I'm overclocking my Gainward Ti4200 650/Ultra XP Golden Sample using the Detontator 28.32 drivers and RivaTuner, with that I'm only getting 300/540 out of it. I'm not doing any AGP overvoltage. After initially overclocking it and fine tuning to what appeared to be the highest stable settings, I tested it with 3dMark 2001 SE and it played through without any problems giving me a score of 8274. That was a day ago. Now when I run the benchmark it locks up. Aside from the benchmark crashing, my clock speeds seem low compared to all of the reviews I've read. I haven't had a chance to try Coolbits yet, but I'm going to try that today. This is my first venture into OCing video so I'm at a loss. Any ideas?

I think it might just be the card. Many people are complaining about bad overclocks with the Gainward GF4 cards. Gainward was probably the best overclocker in the GF3 cards but not so on the GF4 cards. Many people have been having good luck with LeadTek and Abit GF4 cards

Well you've got a damn nice system Make sure your pci/agp is set to pll16 in the bios , this will keep your pci/agp at spec at 33/66 at 133fsb which I see your running at {2.13ghz } , next try your host/dram clock ratio in the bios at 2.0 this will put your memory at 266mhz, although it should run at 2.66 which will put your memory at 353-354 mhz ,this might be a little high for 2400 ddr .
