So after days,actually weeks of trying to get some ati cards to keep busy and get work I threw in the towel and put everything up on ebay.

I purchased a EVGA GTX 570 Classified for crunching. Its basically a gtx 580 board with a 570 processor on it and is one of the highest factory over clock 570 available(@822MHZ). It runs at a relatively cool 63C with 57% fan. It is blowing my twin 8800(gts and ultra) out of the water.

HOWEVER.....
Both this morning and yesterday morning I wake up to it running at 405MHz...WTF Which bumps my processing time from 12-14 minutes up to an hour.
I over clocked it last night hoping that the change in clock speed would make it stay at 888MHz.
This morning when I found it at 405MHz I opened up msi afterburner again and tried to bump it back up...no response. Stayed at 405. After a reboot humming right along at 911Mhz

Any ideas?

I signed up for the forum on evga but apparently you arent allowed to post when you are new.

This just happened in less than 2 hours this morning...my card is now running at 405MHz again...

See my posts in this thread. Had the same issue. Was either Precision or drivers (uninstall of Precision and clean reinstall of drivers fixed it.)

Cool Cool I was just gone for a 5 hours....Only had the clock turned up to 841Mhz card got up to 67C but stayed running at proper speed...Could have be undervolting it for the 888MHz and 911MHz I was running at when it downclocked.

When it down clocks the GPU to 405Mhz it drops the memory from 2200MHz to 162MHz. Major performance hit.

I will reload the drivers.

I have found many many thread on the net talking about GTX 2XX series doing this as a power saving feature( and doing it in the middle of game play). However all the fixes point toward the Rivatuner tool which doesn't work with my driver, or anything new than the gtx 295.

The downclocking is a hardware failsafe feature, and it might happen for a lot of reassons, ranging from too much OC, too low voltage, not enough power from the PSU, too high temps, a hardware failure in the card itself, an incorrect shutdown of a GPU app, a failure of the drivers installation... but there are times that it just happens with no explanation at all...
Afterburner has an option to avoid (in some extent) the downclocking due to power save, but none of those utilities can stop it at all, due to its hardware nature.

IIRC, there are driver problems with NVidia drivers, the 290.xx series
suffering from the Sleep-Bug and too low performance with the (latest?)
300+ series.

I still use 275.33(GTX480) and 281.22(GTX470) NVidia drivers.
Newer drivers on my AMD/ATI HD5870 GPUs (cat.12.4).And have 2 out of 8 cores
freed for 4 SETI/Einstein WUs.
(Einstein uses 2x 0.5CPU + X GPU, is 1 core, the second by BOINC7.0.28:
use 87,50% of the CPUs, is another core, 2 total).

Since those 2 cores never reach 100%, besides loading time, I've INcreased
the 100MHz base-clock to 104MHz. 4 x 34(multiplier)x38(turbo), CPU FLOPS
increases also, as is the DDR3 1648MHz DRAM, system appears even more stable.
I never OC an GPU as they are less protected against PSU instabillities, mobo-issues and heat.

My ATI GPU host draws more power on +12V,(378Watt) then all other voltages together.(115Watt), CPU*/DRAM/Mem-Controller* included. (*Build in CPU)
Both are maximum readings.
A 1000Watt PSU was needed, for (+12V) stabillity.


That kind of contradicts the abillity of the PSUs used.

Snowmain, do you have your GTX 570 set for maximum performance mode or adaptive performance mode?

On gpugrid, which is the BOINC application where my GTX's (480, 275, 260) or used at, I have to set all my GTX's to use maximum performance, are they will constantly down-clock to a lower setting.

To enable maximum mode, (Windows 7)

1.right click on your desktop

2.choose Nvidia Control Panel

3.choose Manage 3D settings

4.in Power Management mode change Adaptive to Prefer maximum performance

5.Then be sure to click on the Apply button.

The GTX 570 Classified is an GTX 580 Board with a 570 processor on it. Its power system is significantly more capable than a standard 570 or(as best I understand it) even the new 797MHz Superclocker card.

That all being stated I was under-volting it. I haden't upped the voltage when I bumped the clock up to the 900 range...cause I am a NOOB, and shouldn't be playing with fire.

I have lowered the overclocking to 835.5MHz which is still 103.5 MHz over a standard GTX570 and it has run fine for almost a full day. Assuming I get home from work and everything is humming along than there is no doubt.

I have the memory bumped from 1950Mhz to 2001MHz. Pluntie. I may even back it all off to the standard 822/1950.

Thanks everybody.

You were undervolting it and pushing the OC even higher than the factory OC?
'S no wonder it would downclock.
Even with proper drivers and standard voltage, any GPU will auto downclock if you push the settings too high.

I don't mean to be sarcastic, but if it was so obvious, why did you post here asking for help because it was downclocking?
Hmmm.

No matter....
I am glad you are getting it all sorted.

Very usefull advice, just as most of us BOINC users will enter Energy Setting switching to High Performance Mode.
Or PCIe settings.
