Greetings Community,
I'm experiencing an odd stability issue. My i5-3570k is overclocked to 4.5Ghz. I have ran both IBT (on stress level: very high) and Prime 95 (blended) many times without so much as a hiccup, but WoW freezes after about 2 minutes of game time. I have played several other games (Skyrim,BF3,TF2) with no such issues. When I reduced the clock speed to 4.3Ghz, WoW no longer froze. My system appears to be stable at 4.5Ghz. Any thoughts on why WoW would have stability issues while nothing else does? Thanks for your time.

V/R,
Daniel

Hi ! I would say that your Oc isn't stable if reducing the core clock correct the problem...

I would suggest to up the Vcore by a notch or two for your 4.5ghz (depending on where you are now, max 1.35V for 24/7 usage with good cooling and make sure you're not overheating)

IBT don't stress all instructions that the CPU can make, also make sure to do 24H testing methodology to make sure it's stable (only 15min isn't going to reveal non-stable OC when you're closer to the goal)

Try multiple stress test (not at the same time), Prime 95, Everest (now Aida64) stress test and IBT and at minimum 6 to 12h each and that's the minimum as any shorter maybe wouldn't cause the system to fail as it's only that 1 set of instructions that only WOW...

maybe its a ram overclock that is causing the issue, Very High only is set to use 4gb of ram make sure it stresses all ur ram or run a synthetic benchmark that will stress the cpu, gpu, ram. Or just lower ur ram freq at 4.5ghz.

Also IBT only stresses the cpu and how much ram u tell it too so could be a system stability issue when gaming and not when running IBT or Prime 95.

Final thoughts Bad ram, too high of a ram OC or complete system instability at 4.5Ghz

PS: do you get a BSOD or just a WOW closing without error , freeze all times ?? Please list your error if you have one and also, does your GPU is OC too ?? Do you OC by the Base clock or only by CPU ratio and did you disable all power saving features + Turbo Boost and EIST ??

Sometimes reducing ram ratio will help the internal memory controller (some chip have really bad controller and can't stand 1866mhz at OC speed, in fact i had a 3570k at 4.6ghz with 2133mhz, can reach 4.8ghz but can't go higher than 1333 on ram at 4.8ghz while 2133 at 4.6 is ok... My 3770k also do that, can reach 5.1Ghz but with 1600ram speed, can't reach 4.8Ghz with 2133 except if i go 46 ratio and 105 baseclock for 4.83ghz and 2240mhz ram...

I overclocked by means of baseclock. I didn't change the ratio. I also didn't change my vcore. CPU-Z reported a max of 1.144 as my vcore. Since it appeared stable, i enabled all of the power saving features and speed step/turbo boost.

Well that's your problem, revert the base clock to 100, disable all power features to find your max CPU ratio and you'll never be stable at 4.5ghz with 1.15V Vcore, impossible even if you have the best I5, you'll need more than that... 1.15V (about stock Vcore) is enough for 4.2 in general, maybe 4.3ghz (unless you're on AUTO, the Vcore won't raise with the OC...)

Once your max CPU ratio is found. I expect 4.5 to 4.8ghz depending on how much voltage you put in) then you can revert power saving and turbo boost while downclocking your overclock (as turbo boost still do 400 mhz more even once OC so 4.5ghz is in reality 4.9ghz so likely to crash)

For 4.6ghz (for the 3 3570k i've been working on) you'll need about 1.32V of Vcore without any other tweaking, setting only the Ratio to 46 and 1.3250V worked for me on the three

4.5Ghz was working at 45 ratio and 1.2750V Vcore on the 3 3570k

depending on your experience you can go higher or don't play the last details as pass 4.5-4.6ghz is more than just ratio and Vcore in general, you'll need specific IMC voltage, PLL Overvoltage and maybe low or high PLL depending on your chip (undervolting my PLL to 1.7V work fine with my 3770k and 1 of the 3 3570k, the 2 others like high PLL so set to 1.85V) and maybe more settings as i passed about 1 week setting all details for my overclock...

PS: make sure Spread Spectrum is also disabled and never touch the base clock if you're not experienced as it's only 5-10% gain in performance but can corrupt data and burn GPUs, HDDs, etc as it's raising all the PCI-e lane, the SATA controller, ram controller and any goodies that are linked to a clock (so any card in a PCI-e slot like network cards...)

Pardon my ignorance, but I seem to have incorrectly stated my method of overclocking. I did not change my base clock. It remains at 100. I merely changed my multiplyer to 45. That is how I achieved 4.5Ghz.

No. After reading that large post, I realized I had incorrectly explained how I achieved my overclock. And, apparently according to that big post, changing the base clock can be a bad choice. I didn't want my mistake to be the basis of an incorrect solution to why my system was unstable.
