4870 1GB F@H performance

F@H GPU is much better optimised for Nvidia cards atm, so yea our ATI cards won't touch them (in F@H) for now.

Don't know if yours is about right or not but my HD 4830 o/ced 625 MHz (GPU, from 575) does about 2400-2800 ppd when run along side F@H SMP (so GPU client doesn't totally have it's own core).

Btw isn't your GPU temp(MEMIO) a bit high at 92C!?:Q

Oh wait, are you constantly displaying the graphics? I think that severly sucks up some GPU power, but I defer to someone else more experienced than me about this as I'm a newbie. (I run the GPU console version btw).
Must admit I'd like to be able to see the graphics occasionally.
Is the graphics version as fast when minimised?
 
No direct cooling on the card? Dude, you're gonna destroy that card!!! Do you have a link to the product description of pic of your card? Even the 3870's I bought this year had coolers on the cards. The ones I bought from powercolor had the fans mounted incorrectly and they wouldn't spin. They began to cook in less than 5 minutes! I smelled them and opened the case and it was hot as hell. i remounted the coolers properly and they were fine. I doubt your card was designed to handle those temps for a sustained period of time.

Take care of that ....

No, no, there is a heatpipe cooler on the card itself covering the GPU. However, there is no direct cooling on the memory chips. See the above newegg link for a pic of the HSF setup.
 
Well not very at 92C :laugh:
Btw if I were you I would of RMAed those 2 cards, that cooking session would of significantly shortened their lives.

Can anyone answer the question about the GPU GUI client graphics GPU useage?

How's your case cooling?

Btw re closing the window, how soon after did you look at the ppd difference? because it doesn't change instantly.
 
Meh...DDR5 clocked @ 1100mhz, will certainly get hot. I've dropped the clocks on the RAM down to 1050mhz, and that seems to have dropped the temps on them a good 5-10C.

I'm not too too worried about it, due to the lack of direct cooling on the memory. GPU temp doesn't budge from 75C, so the HSF seems to be doing it's job, where it makes direct contact anyway.

Case cooling is ok, but not the best. 2 Front 120's blowing air over the card/HDD's, in a cramped Lian-Li rebadge.

PPD difference was checked about 20-30 min after closing the graphical display.
 
Can you not swap 1 of the inlet fans to make it an exhaust fan? I suspect that would help quite a bit.

Btw I don't understand how closing the graphics would make no difference to ppd but drop RAM temps, that seems contradictory 😕. If your card is working hard to show the graphics (higher temps) then it follows that closing them should boost ppd......hmm I'm gonna checkout the F@H forum & see what they say there.

20-30mins is plenty enough delay 🙂, I find even after 5 mins it seems to settle to any new level, though probably at least 10mins would be a better idea.

Well nothing detailed yet but I did spot this in the F@H forum:-

P.S : be careful with the viewer, it is nice, but it kills folding performance ... so don't keep it always running.

It would seem their must be a difference in ppd with & without graphics, did you compare them over the same WU?
 
I'm sure I could...but more than likely, I'll just grab an Antec 900 on the cheap, and improve the thermal conditions tremendously. So in short, I'm lazy, and will just buy a new case...lol

I figured out what was going on with temp/display/PPD. ATI Tray Tools detected the display as a 3D app, which it should've, and instituted my OC, which it also should've. I eventually did notice closing the display dropped my clocks to 500/900, instead of 820/1050. I probably didn't give the PPD enough time to drop with the drop in clocks/temps.

So, with the clocks set @ 820/1050, and the display closed, my PPD stays at 3606, with the temps the same as in the screenshot in the OP.
 
Ah I see that explains it 🙂, so the display was hurting your ppd but because it was dropping the clocks when minimised it hid the performance difference.
So what you really want is 3D clocks all the time & F@H minimised 😉, what's your ppd if you do that?
 
Close the graphic viewer thingy. It'll have an affect on your folding performance.

Make sure that you're using 3D clocks. And you might wanna get a side intake fan or something blowing on that GPU. 92C is fine, but it's hella hot. Like what Assimilator1 said, it'll definitely shorten the lives of those GDDR5. And I thought that those heatpipe coolers worked wonders....
 
The heatpipe cooler would probably help a lot, if it made direct contact with the memory. As it stands, it makes no contact, just bare chips hiding out under there. Check out the screens on newegg. It's a nice HSF...but it seems the reference cooler would be better suited for providing some thermal relief for these GDDR5's
