I had to underclock my XFX 8800 Ultra to get rid of TDR's

[jrhodes870]

Ok the title of my post says it all. Yes the only way i could get rid of my nvlddmkm driver display error was to underclock my brand new XFX 8800 Ultra Extreme!!! I had to underclock it down to 630 mhz from the original 650! Why does this solve the tdr? I dont know, but it does. Now I am just leaving my two cents on this forum. Dont get me wrong i know xfx is a great gpu vendor, but my $700 8800 Ultra was unstable at its factory overclocked speed. And beleive me when i said i tried everyother solution you could think of trying to get rid of my nvlddmkm error. This was a sad realiztion, but i had to do it so i could enjoy gaming!!

Did you start a support ticket at www.xfxforce.com letting them know of the situation? If not start a support ticket and let me know the number. Lowering the clock speeds is a great way to test, but we dont expect you to have to lower clock speeds to get the video working properly.

Glad to know that xfxsupport will take good care of you ;)

That's interesting...:???: I never tried to underclock my Leadtek 8800GTX when I had those TDR problems. But like many of you already know, I don't have those TDRs anymore, after I lowered my CPU overclock and went back to the 158.45 Video Drivers. :smile:

But, I'll try to remember this, in case those TDRs will come back after my planned re-format and re-installation on Windows Vista Ultimate (I'm still waiting to find the right time to do it during the weekend, but since I don't have too many problems at the moment, except for a few freezes every 2-3 days, it's not that urgent...;-))

Thanks for the info and GOOD LUCK. Maybe you need to RMA the card afterall. :???:

I'm pretty sure that xfxsupport will do the maximum he can to help you solve your problems. :grin:
