Haswell Irregularities

[jfrech14]

Ok so.. I am running my 4770k at 4.4 GHz just as a stable OC nothing extreme and have it and both of my 770s watercooled. After extended periods of gaming like today 7 hours in BF3 ultra settings windows 8.1 just decides to crash a few times even though CPU temps never broke 55C and GPU temps never broke 45C.. Is it possibly windows 8.1 compatibility or is there a temperature threshold setting I need to change in my maximus 6 extreme's bios? I know it is a stable overclock. My ram is at 2600MHz which is stock and my GPUs are overclocked 100MHz in both core and memory clock and I did stability tests with cinebench and realbench (RB was 1.5hrs). I just find it odd because my CPU settled at 42C so it wasn't even 50. It just spiked in the 50s every now and then. Just really puzzling. It really only gets unstable in BF3 from what I have experienced so let me know your thoughts and hopefully it's just Win8.1 ,,,, guess I should try BF4 .. you know.. just to check compatibility haha 😉 Cheers friends

Hello

Test at stock settings with the ram speed set to 1600MHz or 1866MHz. This will rule out any overclocking instability. You mention several times that the system is stable but obviously it is not otherwise it wouldn't be crashing. Also 2600MHz memory speed is overclocked not stock.

I bought 2600 MHz ram so for this ram it is the stock speed. Also I meant stable as in the overclock is stable in all of my stress tests. Even I have been having trouble with BF3 on win8.1 with every clock that I have used. I will give it a go with the cpu and gpus not overclocked. That's a good scientific method to rule out some things. Thanks 🙂

2600 running with your CPU is not stock speed. The Maximus VI Extreme supports a stock speed up to 1600MHZ, every single speed above that is Overclock speeds. Your CPU also supports up to 1600MHz as a stock speed...all other speeds above are Overclocks.

Ok technically yes I see where you're coming from and understand that. I just meant it as a ram kit it's rated speed is 2600 and this motherboard is built to handle it but with the cpu the supported speed is 1600 so la te da haha. Thanks intel for making the better cpus with so many restrictions haha. I am playing right now so I will give clocking down a try later. I don't like seeing my cpu go over 55C so I take a break once it gets around there. I know it can do more but it isn't delidded and i want to be careful. Thanks you guys and ill see how it goes

BF3 was designed to run on Win 7 x64, have they patched it to run on 8.1?
Have you tried running other games?
Give BF4 a whirl, it runs very well on 8.1 btw.

Yeap, those values on the stickers on the RAM modules are the XMP settings... - the tested highest OC they can run... but in order to run the RAM at those settings, you don't have any guarantee... specially not for those high speeds, because it also depends on the CPU's IMC... - which in turn was certified for 1600MHz...
