Stress tests, are they even credible??

I don't know if this is the right place to post but i figured stress testing is usually a product of stable overclocks.

Right so the problem i am having at the moment is this. I am in the process of overclocking my 7850 2gb (gigabyte) and im using trixx to unlock voltage. Now with this i can set my core to 1200 and mem clock to 1450 and pass furmark tests easily.

However as soon as i go to game at anything over 1060 i get a red screen freeze straight away. Ive played with all voltage, mem clock and core clock combinations possible above my max (1060/1400/1.18v) but all get a reset of drivers or a red freeze screen.

My little gripe is this. My FX6300 can o/c to 4.6 and pass intel burn or Prime 95 with albeit high temps (65ish) but get no errors, but yet again try to play a game or rip a blu-ray to mp4 and i get a BSOD after a minute.

Why would it be that stress tests don't stress my components to failure? I would like to be able to define a point where my system is becoming unstable, but it makes it hard when so called "Stress Tests" define everything as stable, but then as soon as i go to game of do heavy work like video encoding it fails miserably.

Does anyone have any suggestion as to why this is the case ( all cpu stress tests i have only push core and clock to 80%) and why would heaven/3dmark11/Furmark run but games won't?

Sorry for multiple threads on this whole overclock/stress testing scenario, its just pretty hard to get a straight answer. Most people even after reading most threads just tell me to use intel burn and Furmark. Sorry for my frustration im just trying to find out why my card is hitting a wall at 1060 even with voltage unlocked. Is it a problem with gigabyte Bios or are all these stress tests rubbish?

Stress tests only test the CPU and system memory, they will get you in the ballpark of stability but gaming crashing is a sure sign the CPU supplied voltage needs to be increased further.

I always test for stability using the stress testing first like IBT (Increasing it's stress level each time it passes successfully), then once that's stable, add the GPU load by using benchmarking programs set on their highest capabilities which usually requires a bump or two in the voltage above what the stress testing said was OK, then on to gaming which adds the sound load as well, which sometimes requires additional voltage as well.

Then once you are no longer crashing in games you're pretty much there.

There are also other reasons for crashing system like you could be running your memory faster than it should be or wrong timings and voltage, BIOS settings incorrectly set, or your power supply inadequate, etc. etc. etc.

Yea i have noticed that my standard voltage is 1.41 but drops to 1.32 while running prime or intel burn test!!! i have tried to set the voltage manually at pretty much every setting from 1.38-1.45 but the max voltage will never change. I have never had any problems with cpu stability so far with anything under 4.2 i can finally run load temps around 58 with my hyper 212, hell i've even ran Intel burn at 4.6 and passed on highest settings, albeit with rediculous temps so its out, and im running the good old 4.1ghz with good temps.

The thing that is bugging me is specifically the video card O/C. I can run furmark/3dmark11 all day at 1200/1400/1.2v but can't game any higher than 1060/1350? So obviously htere is some kind of instability somewhere. Ill just run my card at 1060/1350 and everything will be fine. I would like to know if cpu is causing the red screen though and sound crashes! I just assumed it was the video card straight away.

I suppose I should probably buy a better GPU if im chasing more frames instead of tyring to cook on my current one. Cheers for your advice mate.
