i7 3820 CPU stopping/major lag spikes, low settings in BF3 with GTX 690.

Hey guys,

Got a problem here.





Getting serious lag spikes or stuttering with the CPU, have no idea what's causing it but the game literally stops and then stars again it's that bad. Not a slow down, it stops. Doesn't happen always but every 3-4 seconds it does and usally happens in rapid succession.

CPU was set at deafault settings, I have it now OCed slightly to 4.3ghz, no change. GPU usage is low, around the 50% mark and CPU usage is high but not over 80%. Hyperthreading is off, this didn't effect it at all. Windows core parking is off, this didn't help. All my settings are currently on low. Ultra makes no difference, AA makes no difference. CPU ain't too hot, it's never above 55-60deg, GPUs are never above 50-60deg because as I said they aren't being used more than 50%.

I'm really confused. It isn't the GPU, it worked fine in quad SLI with my i7 2700k system I recently sold and quad SLI was smooth as butter, not to mention this happens regardless of settings, low, high, ultra etc. Limiting the FPS produces horrible results and it's better not limiting it.

My specs are:

Windows 7 64bit

i7 3820 HT off with default settings
ASUS X79 Sabertooth
Corsair Vengeance RAM 8GB @ 1600mhz
EVGA GTX 690 @ default
Corsair 60GB Force 3 SSD
Silverstone Strider Gold 1000w

What could cause a CPU to behave like this? Couldn't be the video drivers, in the graph the GPU is uneffected, yet the CPU is just stopping for some reason. Could it be the RAM? I did have issues with the RAM when building/installing Windows 7. Will try changing DIMM slots which was the problem but I'm doubtful it will work.

Please help

EDIT: Have tried different motherboards, different CPUs all with the same problem. What could be causing this kind of CPU behavior? Because on low settings in BF3 an i7 3930k with a GTX 690 doesn't have any performance issues, alos have very low and bad 3DMark 11 scores around P12000 which is also bad.

It stutters every few seconds. GPU usage drops to 10% when it happens and then suddenly increases again to 50-60%.

I have sitting next to me:

x2 X79 Sabertooth Motherboards
i7 3820
i7 3930k
Corsair Vengenace 16GB RAM 1866mhz
Corsair 8GB RAM 1600mhz
x2 EVGA GTX 690s
Corsair 60GB Force 3 SSD

Have tried both CPUs in both motherboards, with both sets of RAM and still have the same issue. Used the same SSD and GTX 690. So I'm really confused what's causing it. 3DMark 11 gives really low scores/bad performance but the stuttering isn't as bad P11000-13000. And this is on a clean install of WIndows 7 64bit.

The GTX 690 is fine and so is it's drivers, it worked beautifully in my P8P67 i7 2700k set-up P17000. The SSD worked fine before I formatted it. Can not correctly formatting an SSD cause these problems? Outside of that the only think I can think of is software/drivers but what on earth would cause my CPU to act like this? Both of them. Low or ultra settings happens just as bad.

Same motherboard just have 2 of them and tried both of them. Both X79 Sabertooths and bought them both yesterday.

Tried 2 sets of chipset drivers but was about to wipe and re-install both of them next to see if it helps. Tried the last 2 sets of Nvidia drivers and the latest beta drivers.

SSD driver, ran a benchmark with the it 3930k which is having the exact same issues and scored higher than my i7 2700k system which was done a week ago so it isn't the SSD.

Also both sets of RAM are good.

Guess it has to be driver or software related. Which is just weird!

This has happened 28 times in the last 24 hours in event viewer but no critical and no warnings, found this in errors. Everything else is errors was pretty insignificant.
