Very happy with the stock performance and it really runs cool (26C idle and 56 on load).

It's not a good overclocker though tongue.gif
Can only get +145 on core. maximum boost clock is 1202.

First post mate! Lol. Thanks for the compliment.

How can you manage a 26C idle if our average ambient temps here in our country is 30~32C? smile.gif Are you running the AC when you tested those temps?

For my Gigabyte GTX 670, I get around 34C idle and 64C load and this card is considered cooler than the ASUS.

yeah AC is on and room temp is around 25-27C. If AC is off i get 30C on idle and 60C on load at 50% fan speed.

Oh ok and I remember you told me that you modified your fan curve already. Enjoy!

Well if usually you're FPS is relatively high (let's say 60+) and then for some reason you drop to 30 but your GPU usage is only 40-50% at that point the CPU is the bottleneck.
Most commonly this occurs in games that don't optimise multi-core very well. Like Guild Wars 2 tongue.gif But that being said, a mild OC to say 4.5GHz usually reduces the problem significantly, which is what I found.

CPU usage ingames will be 90-100%, and GPU usage will be 40-70%, fluctuating. I have watched youtube videos of people playing the same games I do and they get 98-99% gpu usage constant, while i will get dips to the 40% sometimes. It's either my craptastic Athlon or the new GPU i have is faulty.

Considering GPU dependent tests such as 3dmark11 GP score and Heaven give me 99% constant usage and give me scores relative to other with 670 gtx. It must be my CPU. Also my 3dmark 11 CPU Physx score is ~ 3400, which is about a 1/3rd of what newer cpu's such as the 3rdgen i5 and i7.

Here is my 3dmark 11 score with a 670 (Stock Clocks) + Athlon 2 x4 640 @ 3.3g :

As you can see relative to others my gpu seems fine and in range while my cpu is severely lacking. It is what hlding this card back.

How do you monitor CPU usage when runnnig 3DMark11 and Heaven?

So for my CPU overclocked to around 4.5GHz I will less likely to have this problem?
post #1377 of 3357
Yeah @ 4.5 you should have no issues. To monitor CPU usage in-game is rather easy, here is a video how-to : http://www.youtube.com/watch?v=YnaJ81exEw0

So I finally got around to OCing my gtx 670 FTW and I feel like mine is extremely unusual. I followed the long way of doing it and got to +74 core and +895 mem all on stock voltage (1.175v).

The mem OC is making me a little worried, but I never noticed a single artifact until I hit 1000 (with +0 core, following the guide). At 1000 it crashed so I backed down to 900 and there were no artifacts. I then turned my core to +75 (which was the highest stable I could get when doing core only) and noticed some artifacts with +75 and +900. I backed down to +74 and +895 and didn't notice anything.

I did all of this running Heaven benchmark. Before the OC I had a score of 1315 with 52.2 avg FPS and after the OC I had a score of 1493 with 59.3 avg FPS. My score/FPS never decreased while I was increasing both mem and core. In the hardware monitor, my voltage, core, and mem are all completely flat lines and don't fluctuate at all.

I'm running on water so my temps never went above 33 C. I haven't run any other benchmarks yet. Does this seem alright to everyone?

What settings of Heaven are you using? 52.2 FPS before OC is really high already..


Here are my before and afters on my 670.

Ah I forgot to mention that my resolution is only 1680 x 1050 (my good monitor is at school and I'm home on vacation). All settings are maxed out.
