What chips do they use on the retail 660's for memory?

Mine will go as high as 3800 before I see artifacts, but I generally keep them at 3500 for an even 7000mhz effective speed. It doesn't show any scaling beyond that, probably due to the small bus.

WOW!
post #924 of 6757
My chips are H5GQ2H24MFR-R0C, 1500mhz 6000gddr5 effective chips...

guess I'm probably not going to get much more out of them...

After doing some checking, I wouldn't compare my memory results to others here. It seems like the 660 retail cards ship with either Samsung K4G20325FD memory IC or Hynix H5GQ1H24MFR-R0C IC's.

My cards do have Hynix chips, but a slightly different model: H5GQ1H24AFR-R0C. It seems to operate at a higher voltage than the other two which are considered "green" modules. Maybe that is the difference?

1215 boost 3366 memory...



Not bad, But I wish my cards would stay at the boost clock of 1215 more, I think they are actually at that speed for 1/4 of the test...

Thats a pretty good score though. My cards don't like to budge past 1202 in SLI, so I'm pretty much stuck there. But they don't throttle at all which is nice.

another strange thing is if I set a fan profile on EVGA pre, the card will stay in the 1164 area and not boost to 1215. Even though they are staying cooler... ~70c. If I turn the fan profile off, they will get to 80c but will actually get to the boost speed...

It's about 2 fps difference in valley with fan profile off

Try using afterburner? Never had anything but problems with Precision.

You think your processor might be the cause of that? Mine run at Pcie 3.0 speeds so i don't know if that makes a difference.
