Graphics card OC problem?
I don't know how to describe it in a good way.. But I'll try.

So I was was doing a benchmark (Unigine Valley) with my graphics cards (GTX 690) and scored 3280 score. Then I was gonna redo the test. but with Over clocking.

Using EVGA Precision X. Put Power Target on 135%. Then put the Core speed on +150 Mhz and MemClock offset to +200 Mhz.

Then put fan speed on 95% to prevent heat damage. The temp was slowly increasing. Once it hit 76° Celsius the screen went black and the fan speed went down to ~30%. Saying the clock speed is still higher. The temps not going higher than 82 degrees.

BUT, I got the same score. 3280.

What may have caused the problem?


TL;DR
Tried OC, Screen went black, frequency was higher, got the same score, what do?

Oh, I'm sorry.


Lol, no need to be sorry mate :) 

Is it working out for you ?

That looks like the default auto settings for the fan.
I may be wrong though.

There should be a "Fan curve" button near the fan speed on evga precision on the left.
It's better to create your own, depending on your need. But here's one that should be fine:

hmm.. So what should I put the custom fan curve on?

Focus on your gpu core clock first, then worry about the mem clock. And set a custom fan curve for your fan, it's better than the fan always running at 95%

VRMs are the Voltage Regulator Module, it's basiccally the power supply to the card, it just gives the card the power it needs, and when they are heating up because of too much power or they are starting to age because of missuse or too much pressure you see those crashes, blue screens, device drivers hanging artifacts ..etc. And if your graphic card has less heat than when it's not oced this may mean that the card did not oc, may even mean it actually downclocked. try using evga's precision and increasing the core clock 20Mhz then doing a furmark benchmark, and see if you get a slightly better results. (Your 690 WILL downclock if it's being push way more that it can handle and it will cause crashes too)


So 20 Mhz increase on both MemClock Offset and core offset?


Also; The temps were lower because I put fan speed on 95% ( I assume )

Yeah even though, temps maybe okay that's your gpu. But vrms and vrams are dying as thats their symptoms..

I'd just keep it as it is :) 


Hmm... Could you tell me a bit mor about vrms.
The temps are a lot higher when I don't OC. (Around 86 degrees at maximum)

When I OC'd, the temps didn't exceed 76 degrees.
