Hot GPU3 units

[Mathus]

I'm using FAH Client V7 so would this affect which WU's I get?

Sweet mother-of-pearl, I was considering getting a newer/bigger psu for one machine, I guess I better make it a priority.

That sounds about right. My 7950 is currently doing about 6.5K PPD. Which is only about 1K more than my 5830 is currently doing. We definitely don't buy these cards for their folding capabilities.

There are a lot of variables, but in my case it's mostly due to close proximity of SLId cards... one card is currently running @ 70c, the other @ 84c.

If this keeps up I may just end up running a single client on the cooler card.

Why is it that the AMD cards are so horrible at folding? The AMD hardware is comparable with NVIDIA so is it just lack of optimization with the hardware?

[great_big_abyss]

AFAIK Nvidia worked with Stanford to develop the GPU folding client. As such, they optimized it to work better with CUDA than with OpenCL.

EDIT: Also, there's an updated version of FAH V7 (7.1.48), so make sure to grab that and see what it does for you.

[Mathus]

Thanks I will make sure to grab the update! I probably should finish my current WU's before installing eh? I wouldn't want to lost any progress.

*Edit* Looks like I am running version 7.1.43 so I'm already several releases behind :S Here's hoping that this helps my PPD a bit.

[great_big_abyss]

Here is the Link to 7.1.48

You can install the updated client without losing your WUs. Just pause and close your current client, and install the new one into the same directory. It will install over your existing client, and you'll keep on folding right where you were.

And I don't think that it will help your PPD too much. I think that mostly they just made the PPD calculations more accurate. But it IS always a good idea to have the latest version. Also, make sure you AMD drivers are up to date. I think there's a new beta one floating around somewhere. Not sure where it is. If anyone knows, let me know, I have to install it at home!

They actually do not make a bridge capable of 1-4-7 tri-sli , so it's not surprizing you can't find one.

I run the first two in sli , 3rd does phys-x when required.

Probably not a bad idea... The power supply that bit the dust was a 550 watt OCZ... prior to the new work units it was running @ 460-470 watts IIRC according to the watt meter I have, definitely within spec but pushing it just a little... Not sure how much more power the new units draw but it was enough to pop the 550. Anyway, thank you 8031/8033 Now I get to buy a brand spanking new psu
