I have had my i5-2500k @ 4.6 with 1.35v set in the BIOS ever since I built it, it was stable in Prime95 after around 12 hours so thought it was good to go.

However I have just began playing games on my system and found out that it freezes in games at current settings.

Should I just set the CPU voltages to auto or can someone advise on an acceptable voltage to set manually.
 
Is it definitely the CPU? Could it be the OC on the graphics card?

Up to 1.4V should be acceptable IMO.

Its definitely the CPU, I have since set the GFX card back to stock settings and it still froze when the CPU was overclocked. Once I set CPU back to stock settings it no longer froze.

The game I am playing is NFS Rivals.
 
LLC.

Under Prime, due to LLC it'll put more voltage into it, hence stability.
And with gaming, that's why you'll get instability, as less voltage getting put in.

sure its not memory cpu/vtt related?

I have never adjusted those as I thought I was stable at 4.6 until I started playing games.

TBH I cannot be arsed messing around making little changes here and there in order to get stability.

If there is nothing quick and easy for me to do I might just leave it at stock settings.
 
with 16gb of ram I would try 1.10v instead of stock 1.05v cpu/vtt

then see if it still crashes,if so try a touch more dvid(cpu voltage)
 
Quick and easy FIX

Leave all settings as is and reduce multi to 45, get on with enjoying your gaming.
 
It could be many things, gaming adds about another 200-300W load onto the PSU and if you don't have a blower style cooler extra heat into the case.

Best way to test is run Prime95 and Heaven at the same time to simulate a heavy game load.

Except that prime95 gives a far higher, more unrealistic load than any game does.

But I guess you can use it to see max. temps, if anything.. It's like furmark for cards, useless.
 
I was having the same problem even at 4.3ghz (which required even less core voltage than 4.6ghz for Prime95 stability).

So what I have done is set CPU to 4.3ghz with core voltage set to AUTO, did a check temp check with Prime95 and it got up to around 63C.

Had a quick blast on NFS Rivals and it seems to be OK, so I am going to leave it like this and test thoroughly before assuming I am now stable.

Yes, that's why it's great for stability testing.

Processors are designed to run at their peak theoretical load so any stock/stable processor will run Prime95 without any issue. The only exceptions are the joke processors like AMD FX 9370/FX 9590 which have laughable TDP's and throttling as a feature.

Furmark is only useless because GPU makers added throttling when they started shipping 200W+ cards that they couldn't cool/power sufficiently. Fortunately, Intel haven't gone down the 'we can't make it run cooler so lets put an artificial limit on what it can run' route yet, it's probably for the best given that their processors are used in industry/science to run 'unrealistic' calculations 24/7.

Why even bother making a dig at AMD's FX 9370/9590 (INTEL FANBOY ALERT)

But anyway the new FX's run prime perfectly fine without any throttling
