Folding@Home News - 5th November - 12 November 2010

Just dropped the shader to 1800 and HFM is now reporting both at about 8k.
Still dog slow compared to yesterday though.
 
Getting 13,616.04 on the 470's o/c'ed to 700Mhz
Getting 11,718.51 on the 460 o/c'ed to 900Mhz

All on core 2.14 and all running 6811's
 
Spat bother and blast...

I can't run AutoCAD and 6800 at the same time.
will even blue screen on AutoCAD startup with the wu paused!!!

Was working fine last week with 6800.
Might be a Version 2.14 + 6800 + autocad issue
will see if it's just a startup issue... and I need to have CAD open before Fahcore starts

Edit: That's better, running both now - autocad is lumpy but useable.
Must be something in the startup of CAD that clashs with Fah and causes a reboot.
As when running they work together.
Which would account for why yesterday it wasn't an issue when I had my first 6800 in a while

I find the monitoring graphs in MSI correctly reflect the clock speeds of various parts of my cards well. I only use GPUz occasionally.
 
Yeah the graphs in MSI show the actual clocks, that's how I spotted mine had throttled, the settings still showed the clocks as what I had set them to.
 
I'll replace EVGA with Afterburner then.
Just installing the new MB and reinstalling Windows then will start again. I was hoping for Tri-sli but that will on;y really work with single slot cards or watercooled cards.
 
The LARGE atom count WU's (6800 & 6811) are more shader count dependent, than shader clock dependent.
Hence why 470 and upwards show no slowdown.

450 and 460 (and 430) have massive ppd drops on these units, it's not just you emailiscrap, I'm down from 15k to 11k on my 460.
And my 460 just melts with 6811 - not had one pass 1% (thankfully i've not had any since I turned off advmethods only 6800)

As ReaVerUK also said they make the gpu run hotter - this is especially true if the shaders are over 800 (another reason why 470 and 480 are less effected)

So what are good clocks to have on the 460s? I know with the GTX260 I always found the sweet spot at 525 Core, 1500 Shader and 999 Memory. Is the theory the same with the 460? Lower clock and mem and push the Shaders?

What is a "safe" temperature for the card?
 
You can't, Fermi locks the core and shader clocks together. (shaders = 2x core)

Mine seem fine at 1.002V and 900 Core (1800 shaders) under water, but YMMV so I'd go to 800 and see how you get on.

Usually it is the third card that proves the issue with most cases, assuming that is your issue. You need one with 8 PCI slots as aposed to the usual 7.

As biffa said start a 800
My budget palit card hits 850 without any extra voltage.
Runs at below 80c (usually 70c) load with the fan at 40%
In my single fan case, but it is a non standard layout (for what ever reason)

The asus, gigabyte and MSI have much better cooler.
don't even have VRM/MOSFET heatsinks on mine and all the 'better'
chips are speed binned for the sonic/platinum cards.

I'd expect 850+ with a 'quality' heatsink design, but you never know untill you try
 
Thanks for the info guys. It should be arriving today, if not already! [need to check :p]

Probably wont be fitting it for a day or two though.
 
LOL thought it might have been as it rang a bell thats what i'm currently running my 3 295's on. They run ok with similar temps over the 3 cards. The main thing would be to have 'venting' cards to get as much heat outside the case as possible then a good flow of air in the case.
