790i Constant Lockups

[Hapatingjaky]

Hi all,

First time poster to these boards and so far my experience with XFX has not been too great. I recently purchased a 790i Ultra with a 4GB Kit of Patriot memory:

My problem is the system will lockup whenever it feels like it, I could be gaming, I could be browsing the net etc etc the system will just lock, no BSOD, no reset nothing. Nothing appears in event viewer either. I have my voltages set correctly in the bios for memory, timings set manualy, I have even underclocked the memory and it still locks up. About an hour ago I finished running memtest and there were no erros at either clocked or underclocked.

I am a little concerned though regaurding temps. My processor temps are following:

Core 1 - 60c
Core 2 - 60c
Core 3 - 45c
Core 4 - 60c

I am not ocing and I have never seen temps this high before. Recently I was using an Asus 780i with 8GB Patriot DDR2 and I never once had any issues with the setup and the temps have never been so high, I topped out at 45c load before.

Anyone have any ideas as too why this is occuring and how I can fix this issue.... I've been Asus forever and after reading the issues regaurding the Striker II Extreme I decided to go with XFX, I am starting to regret my decision....

When you underclocked the memory, did you increase the timings as well? I would try going all the way to CAS9, 9-9-9-27 2T, to be sure it isn't overly aggressive binning of the memory. Try running with a single video card for a while. If you get the freezing than swap them around and see if it happens with the other card. Is this XP or Vista?

I'm having the same issue; it just randomly locks up, usually within 10-20mins but no longer then an hour.

I've tried: new RAM, different video card(both ATI & nVidia), different HDD(SATA & EIDE), Windows XP & Vista, both 32bit, tried underclocking the RAM from factory 9-9-9-24 to 10-10-10-27, tried swapping the RAM to different DIMM slots, tried my old CoreDuo CPU, tried a different power supply. I even tried a different case. When I had Vista installed nothing came up in the reliability log. Memtest86+ came up negivate. The idling temp for the CPU/Mobo is 55/37C so its not too hot.

I've done a little research and it looks like eVGA customers are having issues with Production 1 of their boards, I'm not sure if that refers to the chipset or not but mine is Production 1 as well.

I've got the same problem just locks up at random. vista 32 just keep locking up on the install but vista 64 installed but its not really usable

Have you guys updated to the P05 or later BIOS?
