670 Overclocking - Oscillating Frequencies??

post #1 of 9
Thread Starter 
Hey guys I have the asus 670 gtx TOP graphics card and ive been following the "Master 670 Overclocking Guide" that is posted on this site. I have gotten my offset to +91mhz which puts my core clock at 1150mhz and my boost at 1228mhz. It gets through the heaven benchmark fine but when I monitor the frequencies with precision x I see that the clock speeds are all over the map anywhere from 1110mhz to 1306mhz. What does this mean? Ill post a picture below. I have the voltage set to max and the same with the power target (117%), also my temps are not exceeding 70C, the highest it got to was 65C. Can someone interpret this for me? I have not touched the memory speeds yet because these ocsillating frequencies are worrying me. Also, am I suppose to keep the power target and voltage set to max or is that bad for the life span of the card. All help is greatly appreciated.

You're being throttled.

Personally find it odd that the TOP card has max. power @ 117% which comes to 185W as per your vBIOS. Anyway, you can see you've reached 121% so it's throttled to keep it below.

Now, you can head to the 600 mod thread here and use the KBT tool (Keppler Bios Tweaker) to change your power target which is more suitable. If it was me, I'd change it to 220W so it matches the "safety" limit (you can of course put it to 225W).

so to manage a higher overclock i need to adjust the powertarget to even higher? Is that bad for the life span of the card?

But look, even at stock speeds my frequencies are oscillating up and down. I was told that they should be pretty much a flat line. It is not throttling due to temps either. What does this mean?

you need higher power limit like 125% or more for that oc, check the 600 mod thread

Dynamic loads cause for dynamic clock speeds. Although your card needs more power.

so is the card suppose to be running at relatively the same mhz throughout the benchmark? In other words is that graph suppose to show a straight line? Should I up the power target to 110% just to run my card at stock speeds? (second graph)

Don't be scared upping the power limit. It only allows the card to draw more power when needed, so take idle or situation where it's not needed.. it won't do it. You need more power
