either chaintech cheated or powerstrip is blind!!

Hey fellas!
I am running a Chaintech GT20 ti 4200 128 MB on 1ghz athlon, and as you might have guessed, I never tried overclocking it as the cpu is the major bottleneck. As of recently, I am hoping to upgrade to a P4 2.4 ghz and thought maybe I should ytry and see how far will this chip allow to push it. So I downloaded powerstrip and checked my defaults. The engine is fine at 249.something mhz but my ram was reported at 405mhz !!!!:Q Anyone else running this card come accross something like this? Is the ram really underclocked or is powerstrip fouling it up somewhere. So I pumped up the ram to around 425 mhz and noticed I could put my finger without burning it for a second or two on the ram chips. Just for the heck of it, I pushed the gpu to around 265 mhz and things looked pretty normal under 3dmark2001se. But when I put my hand below the fan on that thing, I noticed it was spitting more fire than usual. What's the usual ceiling on these chaintech cards? And while we are at it, how can I safely know I aint pushing it too far? And what do the artifacts resulting from ocing gpu/ram look like?
Thanx in advance.

Well AFAIK the default GPU/RAM timings for most cards are stored in the card's BIOS so I'd guess that PowerStrip is doing something weird.

As for OC artifacts... RAM artifacts often show up as "snow" in 3D modes and/or as corrupted icons and mouse pointers and weird vertical lines on your desktop display. GPU artifacts show up as geometry and texturing errors most of the time.

Stock speed should be 250 core/444 memory. You can use coolbits registry hack to overclock.

Go to HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NVTweak

Add the following DWORD values:
"Coolbits" = dword:FFFFFFFF
"NvCplEnableHardwarePage" = dword:00000001
"NvCplEnableAGPSettingsPage" = dword:00000001

this is for 40 series drivers

Thanks viper96720, but I have already oced ram with powerstrip. One more thing, I noticed that the max powerstrip allows me for ram is 539 mhz which even though I havent hit yet, what other software can I use with my 41.09 dets in case I get lucky and get past that 539 mark? Links would be appreciated:). I am hoping to hit ti 4400 levels. People with chaintech ti 4200s, please post your oc results.

I thought stock was 250/500 or so for most ti4200's? My PNY was 250/512... runs @ 300/600 tho. :)

Usually depends if it's a 128MB or 64MB. The 64MB have the faster clock speed most of the time. Got the speeds from chaintechs page. They had 2 speeds listed one for 64
and one for 128
