For any following my GPU stories, here is the scoop:

I installed a second HD 3850 512 MB yesterday. Graphics were beautiful, but not that stable. For example, 3DMark06 constantly crashed at 1:17 on the first game. (Return to Proxycon.) I thought nothing of it, and attempted to use some games. Again, thinks looked beautiful until they stopped working. After a short time, the computer would go into hard lock. I thought that it was possible that my PSU was not strong enough, so I ordered an 850 W model.

Fast forward to this morning. On a lark, I decided to test just the new HD 3850. Surprise, running only that card will ALSO make 3DMark06 crash 1:17 into Return to Proxycon. I returned my prior 3850, which proceeded to make the run though 3DMark06 without even a sniffle. Further, I have just finished playing a 12-hour stint on CoD with it; it is fine.

So, I called up Newegg and canceled the power supply. While I had them, I also had them start an RMA on the new video card. It unfortunately was a gift from my parents, not one I bought myself, and as such, the box must go to them. Looks like I will be without Crossfire for another month.

(>_<;)

Sorry to hear that Blitz

. Hope you get it worked out soon, so we can still pwn you in COD4

wow, thats pretty dam lame!

i am still juggling the thought of wether a new GPU is worth my time ^^
Knowing that anything i pu there will be limited till i do a whole new build in the future.

Blitz, were you able to view the temps in GPU-Z or CCC while stress testing the 3850? Are the crashes random after several hours of gameplay or is after a certain amount of time? It could possibly be a cooling issue. Did you check the TIM on the cooler?

Good luck

Both cards are within thermal spec. The Vantec-cooled one is about 5º C cooler than the stock-cooled one. The hard-locks take about 1-10 *(minutes) of GPU load when in games. (Different CoD maps stress different amounts.) 3DMark almost always causes a hard-lock at 1:17 on Return to Proxycon. If it makes it though, it hard locks about 5 seconds into Canyon flight. This happens in Crossfire or a single-card configuration with the suspect card.

k fine no intel questions then >.<".just wanted see what your opinions on it were.not get freaking flamed. haters...

new question. someone on ocn wanted to trade a Tuniq Tower with a scythe slipstream fan for zalman 9700. good trade? or no? which is better?

StormX2 · 08-21-08

wish i had me a Tuniq lol

blitz6804 · 08-21-08

Absolutely take the Sunbeam over the Zalman. Its cooling performance is superior.

Blitz, were you able to test the 3850 in another machine or motherboard to confirm this? If I am not mistaken wasn't your OS installation from another board? Are you able to run the 3D view from ATITool .27b while viewing the temps? 3DMark and COD4 don't even come close to taxing the card.

Good luck

blitz6804 · 08-21-08

Yes, I ran 3D View from ATItool 0.27b while viewing temps. If I run my first card solely, it'll run indefinitely. If I run the new card solely, the computer will go into hard lockup. If I run Crossfire, there is no crash, but on the other hand, GPU 1 (the good one) is loading at 99% and GPU 2 (the bad one) is loading at 1%.
