Weird GTX 460 768mb clock speed and OC help - Page 2

850/1700/2000 returned with unstable gpu at stock volts
825/1650/2000 has been running for 10 minutes with only slight blips of decreased gpu usage. my PPD jumped up to 12k on this wu.

Ok 2 WU's later It'll sometime get to only 85% usage.

If you consider F@H in particular for your overclock. Find stable moderate gpu and memory overclocks then up the shaders bit by bit and test. But we really need any PPD, find a fast good OC and FOLD ON!!!

Edit: only SHADERS affect your PPD performance noticeably

Hmm it doesn't seem to matter what the speed is at except that PPD drops to 8k on this WU if I set the core to 850 and the shaders to 1900 memory to 2000.
I guess I'll just set it to 825/1700/2000.

I might tinker with it more later but I gotta go to 8 hours of classes >v<

I'm guessing the OP is a troll because I've never seen anyone complain that their GPU clocks are HIGHER than stock. >_>

Well if you read it's an FPB and the speeds just seemed idk weird.
Anyways I should change the title I guess to include OC help it doesn't seem to be folding right.
So if anyone could help me OC this for folding that'd be nice the spikes in the usage are described above.

First off... The difference between the CompUsa page and your card readings is that you have the FPB version of the GTX 460 (Core of 720) and the Compusa page is showing the non-FPB stats.

Ok... My card was the non-FPB. I installed the FPB on it and got your "stock" numbers. I was able to easily move that card up to 858/1716/2000 without any voltage increase. I ultimately OC'ed that card to 895/1790/2046 with a small voltage increase. Unfortunately I am not using that card anymore and I can't remember what my voltage was. I have read of people reaching even higher OC's than mine but I reached what I felt was something comfortable for my purposes and gave me good temps while using the stock cooling on it.

All I can suggest is to take it to 850 and start increasing the voltage in small steps. Then run a quick stability test until it works properly. I have heard that a 15-20 mins. Furmark test is a good quick test to use. EVGA also has what is called the "OC Scanner" that you can use. The quick test is not an all out definitive test. Usually, if a GPU OC is going to fail, it will do so quickly but this is not a hard core rule to follow. It is more of a guide line. Remember to use the "stability" test though... not the benchmarking test if using the OC Scanner. Once you reach a decent OC that you feel comfortable with, run a stability test that goes at least an hour or two so you have a good feel for temps and such. Also, when running these stability/benchmarking tests, use the fan at higher speed. I go between 80-90% of fan speed. It will be noisy though.

Hope this helps. I would also suggest you read over the EVGA GTX 460 threads. That's were I first got my OC information from and it was rather helpful. One important thing to remember though... whatever OC you may read about is not necessarily the OC you will or can achieve. Each card is different. Some, unfortunately, are better than others. Much like with CPU's. You mentioned something like 12K PPD I believe. That's not too bad imo. I hit between 14-15K with a 560 ti to start off with. Once I got it OC'ed, I was in the 17K range I believe it was. I think it can do even better but I need to get numbers up for the team. I'll play with it later.

Thanks I knew each card was different. However maybe you can answer my question there is a problem if the gpu usage drops alot right (I'm monitoring it in afterburner while it's folding) ? I notice sometimes it drops to 60% or so then goes back to 99% it seems to help if I set FAH_Core_15 to above normal (this is while I'm bigadv folding in my ubuntu vm). My 8500 GT just stays at 99% usage the whole time so idk at first I thought it was the OC but I returned it to factory and still even after stopping and restarting the gou client no good.

In connection to folding, I wish I could answer you. At present I am having my own problems in that as I fold, I get these "serious error" messages and my rig stops folding. This has frustrated me very much.

The lowering/increasing of the GPU usage as you fold sounds to me more like a 460 driver thing. Not that the driver is bad but that the driver may throttle back a bit and then increase once more for whatever reason. Reason I say this is because your other card remains at a constant 99%. The difference between that card and your 460 is the driver and the physical construction (obviously) of the cards. They both use the same folding client and the connection is there as a constant thing.

my 460 768MB is currently running at 860/1720/2280
this is a little bit faster in fps than option 2 850/1700/2100
then standard overclock for evga 763/1526/1900

current 115fps
http://www.overclock.net/attachment....1&d=1309408672
option 2 107fps
http://www.overclock.net/attachment....1&d=1309408672
standard evga oc 96fps
http://www.overclock.net/attachment....1&d=1309408672
frame rates were gotten by the EVGA OC Scanner 1.6.1

still yet the frames that i gained are nothing compared to just overclocking the 1gb version. even stock the gig version almost destroys it and oc no comparison.
