You shouldn't be seeing anything like that with stock settings, I'd be looking into that

Yeh im having issues too. OC'ing went good then when i tried playing bf3, it would crash. so started bumping down mem clock offset till i find a stable gameplay. Had to drop it by a fair bit so far which sux >.<<br />
I have a ZOTAC GTX 670 AMP

Did you have to drop the core clock? I only had to drop the memory by about 100mhz, which has resultet in about a .2 drop in FPS in BF3, and .5 in Far Cry 3. I found that generally speaking, BF3 seems to scale more with clock than memory, compared to other games/benchmarks

Hi all,

Sorry to butt in but I'm just curious with my OC since this is my first time doing it. Is this result okay or a bit low? AGT 160-550.docx 763k .docx file .
it's a GTX670-DC2-2GD5 with GPU clock +160, Memory clock +550 and all stock voltages & power target. If it makes any difference, CPU i7 3770K OC'd to 4.5Ghz. Personally, I didn't see any gains in FPS while playing MOH Warfighter. Did I do something wrong? At GPU clock +170, it would crash heaven half way or even sooner and that even with max power target and voltages. This is using the 310.70 driver already.
1 more thing, even at stock or OC, I keep seeing flickering shadows and semi transparent white bars during heaven just like Tagkaman.

You should max out your power target nomatter what, and i would love to see a screenshot of GPU Tweak while the GPU is under load (mid Heaven).
The voltage slider doesen't really do anything, so just keep that one at stock.

Gpu teeak causes problems. Aftrrburner and prec-x are better even though i get different results using either 1 at the same clocks

Just been OCing my 670SLI,

I've actually got 4 670s.

2x EVGA Standard
2x EVGA Signature 2s

They are/were in SLI Pairs, so results as per below,

Standard EVGA
1190 Core (Inc. Boost / KBoost and OC)
6120 Mem
1.175v

Signature 2s (680PCB)
1280 Core - Unlocked KBoost BIOS with +150% Power Target and 0-100% Fan
6400 Mem
1.2120v

Even with voltage tweeking the Standard EVGA pair WOULD NOT go over 1190core and the OC on the Memory was SHOCKINGLY bad. So they are here with an RMA number awaiting return,

The Signature 2's are quieter and about 25deg C COOLER than the Standard cards, yes the fans can still get noisy but because they are cooler the fan wont kick into high gears so often

What should i increase my memory to? Or should i leave it at 200?

If anyone knows of better settings please let me know. volts and power target are maxed out

Here is my benchmark

no one can tell you what settings to use except max out the power target and voltage sliders. every card clocks differently on both the core and memory.

rerun heaven with everything maxed and 1920x1080.

So, you RMA'ed two 670s because you were not satisfied by the overclock?

You need to run the Heaven resolution at your max resolution. And you should keep raising your Memory, until you see artifacts/crashes
