With the new nvidia memory requirnment, does need updating? I updated pointing to it so users can get the most curent info.

Purpose of this thread is to provide feedback for system running both ATI and nvidia cards in the same computer.

I haven’t had major issues thus far with running MOO on my system with the latest app. (computer ID 32)

I have an ATI 6970, a NVIDIA 430 and a NVIDIA 295 all in the same comp.

With the recent app, the ATI card is sitting at 99% GPU load, however the nvidia cards are at 50-53% load across all 3 nvidia GPUs with a core setting of -1. With a core setting of 1-, I get around 80% load across all 3 nvidia GPUs.

The nvidia app still takes a LOT longer to complete than the ATI app. In general, it takes around 15-16 min for an ATI app to complete on the ATI card and about an hour and a half to complete on the 3 combined nvidia GPUs.

In my experience, the ATI setting of .9 CPU is rather high, as it general uses 0-1% of my i7 (8thread) CPU, so that could be lowered. The CPU load for the nvidia app on my system as around 8-10% most of the time.

Completed nvidia tasks so far: (core = 10, 1h 10m) (core = -1, 1h 40 min)

so far i havent noticed any issues with a single ATI 6970 and windows 7x64 with the latest ATI driver.

I am getting the same thing on my nvidia cards. I have a GeForce 295 (dual GPU) and a GeForce 430 in the same machine. Currently, only one of the 295 GPUs is 50% active and the other 2 are completly idle. I to have complete a few WUs on my nvidia card. The single ATI 6970 card in the same computer is working as one would expect.

Might I sugest running one WU on each GPU core instead of one WU for all GPUs? This may minimise issues for systems with a mix of varing card types as well.
