70-80% GPU utilization?

post #1 of 7
Thread Starter 
My GTX 670 only hits up to around 80% GPU utilization max. My other PC, with a 7870 in it, pushes all the way up to 99% utilization.

So I'm sitting here now looking at my 670, chomping on a 0x15, getting 27k PPD. That's crap -_-

I've used the client-type beta tags before but unfortunately it always crashes for me after a few hours or so, even tried downclocking the card. Keep giving me memory errors...thinking about RMA'ing it, however, it's a 1300mhz card for gaming. tough choice.

Is this normal though? I've tried giving up a CPU thread to it (as i do with my AMD GPU), however, that makes 0 difference.

Help!

You have to give up two threads or else WU's tend to fail. Also, memory overclocks do not provide any benefit for folding so I would actually recommend downclocking the memory to make the card run cooler. Let me know if this helps.

Seriously? 2 threads? Wow is that new? I always thought it was just for AMD when u needed to give up a thread! (Might have been fixed)

Interesting though, when I get home I'll see if it makes much of a difference if I take away the CPU slot entirely, or just give up 2 threads

Try running gpu folding on its own without cpu folding too. On an 8900 (beta WU) on my 7870 at 1200mhz I got 66,000ppd. Are you sure you have the slider all the way to full on your fah window and are you not doing anything else with the pc whilst its folding? If i start opening stuff in windows my gpu usage drops even whilst folding.

Yeah I'm sure, used to average 160,000-200,000ppd, slowed down since I'm not trying to keep my AC on while I'm not home all day just to keep my temps in order.

I did recently purchase a MSI z77 GD65 recently. My i7 was 4.3ghz but I lowered it to 4.2ghz this morning because it was starting to push over 84C

I just have a cooler master 212+, amazing budget cooler and perfectly fine for gaming, but I need a little better head dissipation to really push that any further.

My 7870 gets around 50pdd, I think its at 1150mhz, never played with it before but it never heats up past 60C (Gigabyte windforce)

The 27000ppd my 670 is getting though.... pathetic

Well on core 15, around 30k would probably be normal for a 670, I think when I folded a core 15 on a gk104 core it was ~35k or so clocked at 1215mhz (it was one of two gk104 cores in my old 690).

 

On core 17 it should be much higher ~80k+ depending on the clocks.  On core 17 my NV GPU uses up to 25% of my 3930k, I'm getting ready to move it to a dual core rig next week, and will be interested to see if that will be enough to keep up.

So did you try running without folding on the cpu too?
