Seem to be getting low point WU's...

Ollie1132 · 3 Dec 2013 at 11:41

So I haven't changed anything in my settings. I use to get WU's worth around 15k~ over 12-20 hours. Now I seem to be getting (on my GPU) ones worth 5k and on my CPU ones worth 9k. (Both use to definitely get WU's over 12k points.. I was averaging 40-50k ppd) My GPU is a GTX 670 and my CPU is a 2600k. Any help please because I really don't understand why I'm seeing lower valued WU's (although they take less time.. I'm just getting 15k~ less PPD and it confuses me) I'm running the 326.8 Beta drivers after rolling back from 331.x

is this set up to get core 17 units?

half way down it shows how to add the correct details to make sure you get the best from your gpu which is more than 40 to 50k ppd for a gtx670

Okay so I've just done that. But how come my CPU is also getting much lower WU's :/

Edit:

Also it seems that it's still not getting WU's for 17 cores through.. At least if I'm looking at this rightly.

core 17 are for gpu only but once you pick one up your ppd will rise high, as soon as your current work units ends the new one should be a core 17. cpu work units can be rubbish some times aswell hence rubbish ppd at times, have you allowed a core to be free for the gpu?

Hm I think it's using all of my CPU cores. How would I check? Well the current GPU WU is going to take 6 hours or so. Hope it picks one up thats on 17 cores after that. Been having 30k~ PPD when I was getting 50k PPD consistently since september.

I'm taking it that not having a CPU core spare does something counter productive? xD

amd don't need a free core but NVidia do, it use to be the other way round but the tables turned

Well then. No problems at all with an i7 ^.^ I'll see how my PPD goes after these WU's are finished with. Cheers for the help mate.

Edit:

Next WU on my GPU is 1200 points. Hmm I am utterly confused D:

i7 2600K with a 670? Even at standard clocks that should give you 60k+ PPD if you are 24/7. I assume you have hyperthreading enabled on the CPU which theoretically give you 8 CPU threads over the 4 cores.

The nvidia card does need a CPU slot with the 17 core GPU units, but if it drops back onto a 15 cored unit, that CPU slot isn't needed. However, set your CPU to 6 slots (SMP doesn't work well with odd slot numbers), as that gives it 3 full CPU cores. Both GPU and CPU use can fluctuate, on core 17s but you'd probably see your CPU running at about 90% of total (i.e. it's using more than one thread of one core).

It is a bit of a luck of the draw if you do get core 17 or core 15 GPU stuff, especially as folding are trying to use up the last of their core 15 units. You can increase your chances of the 17s by setting the GPU to the advanced flag. Technically you can use beta, but you should be a member of the beta testers group as those might throw up issues.

If for some reason you aren't completing WUs in their set timeframe, or they are regularly crashing, you don't get the Quick Return bonus, and thus your points will be low. WUs themselves are usually a lot lower in value than their total worth, due to the QRB. Focus on PPD rather than the WU values.

I see. I've got it set so that the CPU uses 3 cores (6 threads). My PPD is about 30k seems extremely wrong. I might try setting everything back to stock. I've got a WU for 6k points on my GPU currently (15 core) which was 10 hours long... Theres definitely something wrong. I only just Picked that WU up this morning as well. Anything below 16 hours of work is definitely getting put in on time most of the time at least.

15 type GPU WUs earn a lot less points than the 17s, so 30k might not be far out if you are getting a few of those. Remember that your CPU being set at 6 slots (3 cores) is underusing your potential output when you have the 15 GPUs. The challenge is getting the lucrative 17s so you can get the bigger points. It may all be for the good of he science, but we also want the rewards

Aha yeah. But I always use to get 12k~ pointed WU's and my PPD was 50-60k :/ really don't understand the sudden drop. Also don't get how a 6k WU that takes ten hours can add up to 30k PPD :/ my CPU's been on a 14 hour WU for 12k points... >.< gief me back my 60k PPD damn you F@H D:

Ollie1132 · 5 Dec 2013 at 12:36

I've never ran F@H 24/7 but I tend to run it at least 16 hours a day. Meaning that sometimes I'd not get the QRB I understand that. I guess I'll just have to keep going through these little 0x15 WU's for now.

Ollie1132 · 11 Dec 2013 at 01:38

Okay so I'm starting to get 0x17s. Just a question... does it require 2 physical cores or just 1 physical and 1 logical? Cause my CPU folds are currently 0x4 instead of 6.

Assuming you have hyperthreading enabled on your i7 2600, then you allocate 1 full core (2 hyperthreads) to the GPU. It will need just a bit more than one hyperthread when paired with a nvidia GPU.

If I recall correctly I could see my i7 2600K with a 670 used around 90% of the CPU, when set as above.

Hm. Must just be that I'm hated for CPU WU's currently. xD been getting 0x3s and 0x4s since I've been having 0x17s coming through on my gpu
