I did see that KieX replied but I'm not sure if he understood the question as I think you meant it. No, you can not allocate more "CPU power" to each running GPU instance. One CPU tread is maximum for one GPU WU. I'm sure that KieX will agree on that. You can use less CPU (good if you have dual core and a 7990 in the same rig) but not the other way around.

I may have to snag a couple of 7770's if there is 6 months left of GPU wu's.

On a dual core CPU would I only be able to run two WU for two GTS 450s or two WU PER GTS 450?

In principle you could run 10 GPU units on each of your 450s but I doubt it would work (errors). You might be able run 2 x 2 (two on each with a dual) but only a test would show. My limited experience showed that running 1 GPU on a 450 was hard enough if you needed to see was was going on at your monitor. Here the CPU would not be the limiting factor but the GPU.

Well this PC will not be used for anything other than crunching so its usability is not a concern. I just wonder what these two would output with 2 WU a piece?

I'll consider some 7770's in the. ESR future then. Seems like they scale really well in Crossfire?

I'm now home for winter break
![]() I brought my i7-920/HD7770 system, the i3 with a GTX470, and my i7 laptop. I also have the Atom, but the replacement HDD I brought is also bad, so it's out of commission until tomorrow. Everything is running now--I'll be shutting down the rest of the systems at school in about 60 hours.

Yea I agree with hammeron, I would get the 2GB cards.

7770's are only 128 bit cards... can they even use 2GB of memory effectively?

Yea, I agree with Norton. I'd get a 7850 2gb with a 256-bit interface for another 40-50 bucks and get two free games (two worlds, Sleeping dogs). The only 2gb 7770 is $144 with no games.. Plus, you'll be able to push that 7850 to 1ghz as well.
![]() EDIT: I believe the sweet spot for me would be the 7870 ghz here it has a really good aftermarket hsf and it's clocked at 1.1ghz out of the box for $229.99 w/ 2x games.

Also, found my cruncher was out of gpu wus again, have to increase cache again. Just made a sizable dump, will be interesting to see what I get.

![]() Sorry its been a couple of days, busy days this time of year, so i left it running over night and all of today. My gpu is running stock and has done for most of its life, only the occasional oc for benching but its been a while and they weren't high oc's by any means. I noticed today that 3 results finished with computation errors, i hope its not a sign of a dying card?

Does anyone know what weirdness this is? It starts out with 4 gpu wus and 8 cpu wus, and now it's doing this?
![]() Oh, and it seems to have paused the bottom cpu wu... which makes sense since only 12 wus should be running... but why did it load it up like that? Weird.

Pete, post the far right side of the client so we can see the status of the WU's. Also post the script your using in the XML file.
Team: Just brought over both Opty rigs, so it should get interesting in the next couple of days!

Okay, I'm now quite confused.. should have 8 cpu wus and 4 gpu wus running, seems I don't:
![]() app info is unchanged from the one I got here...

Well, it's 8 threads. So 4 threads get used up for the gpus? Didn't know that.
Oh, and I increased the work cache, last time I did that it did this too.... Edit: and yes Buck, it cleared out the gpu wus, and now just shows 4 gpu wus and 4 cpu wus... Edit2: man I need a hex core....

I think what's happening is that your setup is possibly competing for the CPU threads. So it starts the GPU, then hands off to the CPU one, making the GPU run late and go into high-priority. If you swap to the 1-1 you will have 4 threads locked to GPU and 4 threads locked to CPU. Should mean you get the full GPU performance and an i5 level of CPU output. Code:
<avg_ncpus>1.0</avg_ncpus>
<max_ncpus>1.0</max_ncpus>

Nope there's no difference in that respect. The default is 1 GPU thread uses 1 CPU thread. If the total number of GPU WU is less than your CPU core count.. best to go 1-1 imho for best output.
EDIT: If you assigned more cores to a WU it would probably make no difference either since all jobs are single threaded AFIK
