Struggling here...

On stock voltage 1135/1200 got a driver reset. Unigine just crashed straight back to desktop. I reset, increased voltage to 1150, same again, crash back to desktop.

Increased voltage to 1160 this time, the benchmark ran all the way through but a few seconds after giving me the score I got a BSOD. Just increase voltage again?

Keep increasing voltage until it gets stable. Double check that the power limit is sticking at +20%. Ensure temps are staying below 70c.

1135/1200 with 1170voltage was stable. 1160/1200 with the same voltage was an instant BSOD in unigine.

Just a bit worried now because I'm creeping up close to 1.2v aren't I?

I'll up it to 1180 and see what happens.
 
Okay. 1160/1200 - 1180v.

Benchmark completed but after I was given my score, Unigine just crashed to desktop. I assume this is a driver reset?

Unsure what the next steps should be as voltage is getting high. Please advise. :)
 
If you could reach 1200core that would be fantastic since it is about 40% OC. But if it is not running stable and cool you could settle for 1150core. This should run stable no problem and is about a 35% OC. The missing 5% percent may cost you 1-2 FPS. Shouldn't be that big of a deal. I am no expert here and just started OCing myself, but maybe try to keep your card cooler? I found that mine could reach 1150core @ stock volts if I used 100% fan speed (max 60°C) and open my case. It still crashed during gameplay but was fine during benchmarking. But obviously this is not practicle or 24/7 recommandable.

1200/1200 @ 1.225 - Driver reset halfway through Unigine.

Gahhh... What can I do now then?

Do I start stepping the memory clock up now?

Cheers

Can't get the memory past stock. Gets to the end of benchmark and just crashes.

Yeah well if I understand all these guides correctly, you should back down from the 1200core to either 1185core or 1150core (there won't be too much difference and while the 1185 might complete the benchmark they can still crash ingame. This you have to test by playing for about 2-3 hours on a graphic intensive DX11 game.)

Then you can increase your memore clocks until you experience any issues (crashes, driver resets etc.) From there back down on the memory core about 20-25MHz and you should have found a pretty stable OC. Only way to find out for sure it ingame testing.

EDIT: May I ask what your ASIC quality is? Just for reference, mine is 68,8% which is pretty bad (hence, the high stock voltage). You can check when right clicking on the top bar in GPU-Z (graphic card monitoring tool) and choose "Read ASIC quality".

Settle for 1175 on the core if you can. Be sure 1175 is stable before you move to the memory.

Yeah I thought the 1185core was stable but I benched it again and it BSOD half way through.

I'll move it back down to 1175 now and see what happens.

I don't know if it's relevant but my exact card is HIS 7850 2GB iceQX.
