I recently upgraded from a gimped 5850 (running multiple monitors would cause display corruption) to a shiny new ASUS 670. I was originally going to go with a gigabyte model, but seeing as the availability was just below 'unicorn', I decided to have a look at the ASUS cards instead. I got the non-TOP version with stock clocks, figuring I could just OC to TOP levels anyway.
Anyway, despite a couple RSOD (gpu tool was causing it) this card has been working great at stock speeds.
A couple days ago I decided to OC, so using msi afterburner with Unigine Heaven as a stress test, I started to crank up the card. Now, msi afterburner unfortunately doesn't list the actual core and memory clocks, just the OC, so I'm not certain whether I'm at 195 mhz boost over the default 915 or over the default boost of 980. However, even at 980 +195 that only brings me to 1175 mhz core. Even with the 670s being somewhat tame overclockers (or so I've heard), this seems quite low. I'm not demanding 1350 mhz here, but I was certainly expecting to be comfortably within the 1200 range. Similarly, my RAM tops out at +325 mhz.
Here are a couple useful facts: My card idles at 25-30c with 27% fan speed and I have a profile that keeps it at 65C and below, even under load. My power limit is only set to 110% out of a possible 130, and my core voltage has not been adjusted (I had heard that this doesn't make much of a difference). The weird thing is, I'm not seeing artifacts at all. At a hair above +195 or +325, my drivers will crash after 30 seconds to a minute of unigine. I run Heaven benchmark maxed with extreme tessellation at 1600 x 900.
Here is my question: Does this mean I just got a mediocre overclocker? Or are there more things I can do to increase the speeds. My card is never going above 105% power usage, but would increasing the power limit help? What about the core voltage? (shot in the dark). Is the extreme tessellation of Heaven causing this? I would like a universally stable OC, but if normal games will run and benefit from increased clock speeds I'll most certainly push the card further.
Any help would be greatly appreciated!
Specs:
Core i5 2500k OC - 4.4 ghz
ASUS DCU II 670 Gtx
Gskill DDR3 1600 8GB
ASROCK p67 Extreme 4 Gen 3
CM HAF 932
750 Watt Kingwin Gold Certified
Seagate Barracuda 750GB (yes, the ones with the absurdly high failure rate. fingers crossed)
I've got a Creative sound card too, if that matters...
