And this heat... smile.gif

Just try it out.

Yo dude . it working biggrin.gif AWESOME biggrin.gif it making more coil whine noise but hey ... its working .

Core = 1293MHz
Memory = 3206MHz
max temp 75C*

Which is the best GTX670 to get for overclocking - one with the least throttling, powertarget issues before/after a bios flash?

One thing i do not like about Kepler is this throttling stuff but it seems it happens when the GPU goes over 70c? so i'm guessing the better clocking GTX670s have better coolers? I was thinking MSI GTX670 PE or Asus DCII 670 would be at the top?

Overclocking is still and forever will be based on luck of the draw. The coolest-running GTX 670 is thte Gigabyte GTX 670 but it is not necessarily the best overclocker. Any of the models can be better/worse than the same or different model, it's just the way it is.

Check the valley 1.0 benchmark - it is almost not CPU dependant and will let me see if this is caused by CPU or GPU. In Valley 1.0 on the newest drivers I got around 40 FPS, on the older ones 41,5.

My CPU can't be OCed alot, most likely because I have 2 2x stick of different ram. I can only do
3.6ghz CPU, 1333 DDR3 ram, if I go to 3.8ghz, 3DMark always crash at the physic, if I go 3.6ghz and 1600 ram, 50% to just bsod randomly.
But I do plan to do a platform change later this year, still waiting to see what TIM Haswell will be using.

I unlocked the bios on my GPU too, it is faster then my previous card, but I'm just not really seeing much change in Ocing the card, unlike my previous GTX 460 and AMD 7870 XT, in which I'm wondering if it's just my card, or the whole GTX 600 serie isn't good for overclocking.

But here's my valley score, any other score you need?

Score in valley is much better. It is CPU bottleneck than.

My 670 FTW does 1800+ in Valley on stock and 2000+ overclocked (ExtremeHD settings). So either the CPU is also bottlenecking in Valley, or the card isn't performing as good (maybe due to custom NV-controlpanel settings?)


Edit: oops, forgot the custom unlocked bios overclocks to 1200+ even on default settings. So naturally i would get higher scores. The Valley-scores seem about right then i guess.

Wow the valley benchmark is so much better looking than the Heaven one.
Here's my score stock, and then with my OC.
Stock


OC - (Power 120%, Core +97, Mem +460)
post #2120 of 3357
OK, I decided to redo some of the test with default setting, and oc difference and I am also wondering, is it normal to have such large FPS diference?
Here are the default settings[






Here is the OC, thanks for bring it out
