XPS 16 GPU overclocking

Anyone scan arctifacts with ATITool or Rivatuner??

I just use FurMark. If you turn up the memory too high, artifacts will start to appear immediately (small, bright blue splotches everywhere for me).

If I launch Furmark for a few hours, I don't see arctifacts.
But if I scan with ATITool, it give me error, because there are arcifacts.

Hmmm... I'll have to try that out. Are you using the one from TechPowerUp?

Yes

Now I'm testing 785-875, over 900mhz gives me artifacts

I just ran ATI Tool 0.26 for 15 min at 825/1100 with 0 artifacts. In fact, the artifacts began to appear in ATI Tool at the same time as in FurMark, at around 1150, and they appeared instantly after raising the mem clocks. Only in ATI Tool the artifacts were yellow instead of blue, lol. Regardless, the tests are nearly the same, ATI tool looks at a stationary piece of carpet, where FurMark looks at a rotating doughnut of carpet

My memory goes up to 1150 without artifacts. It only starts giving me lip at 1200 or so.

Well my CPU score was around 3025-3050 in all the tests, so even though my score jumped from 8000 to 10000 with GPU overclocking, the CPU score didn't change. What were your SM2 / SM3 scores? That would be a better comparison..

Well it wouldn't matter much if the GPU was the bottleneck to begin with. The T9550 gets around 2350 in comparison. That's a pretty substantial difference!

True. Do you know what software tool I can use to overclock the CPU as well? This is my first time trying overclocking on a laptop. I've overclocked on a Desktop a few times, but most desktop overclocking tools seem not to work on a laptop. I wonder how high I can get on 3DMark06 if I overclock both . Not that I'd ever overclock the 720m on this machine in real-world usage, it's just cutting it too close with temps and throttling, but for a 10min benchmark it should work.

I don't think you can overclock it. I don't know of any way, at least. Not much point to it, like you said, though I do get the feeling temperatures on this machine could be greatly improved with TIM reapplication.

I'm buying MX-3 in a week or so, I think.

Yeah, I already upgraded my paste to the Shin-Etsu G751. I looked at a lot of reviews and comparisons, and G751 was usually #1 and always in the top 5. I don't think its that much better than good ol' AS5, though it's significantly better than that poorly applied stock crap.

I idle in the high-40s CPU and mid-40s GPU. I've never had CPU temps exceed 75C or GPU exceed 66C (even in 3DMark), unless I'm running Prime95 + Furmark, which will get my CPU up into the mid-80s (throttling starts at 85) and my GPU to 79C (throttle free). This is without any external cooling and BIOS A11, and room temps around 75F.
