Hey guys, well I picked up a 5930K, a MSI X99A Krait Edition motherboard and 16GB of Corsair Dominator 3200Mhz RAM the other day and I need some help overclocking it as the OC Genie 2 is crap, with it set to Gear 2 as it's known it only does 4Ghz, My 2600K on a Asus motherboard did 4.4Ghz with it's auto overclocking system.

I would really really like to get at least the same from this chip if I can, according to a article I've seen pretty much all 5930K's should be able to do 4.3Ghz to 4.5Ghz.

I've tried doing it myself but not getting anywhere, I put in 44 multiplier and put the voltage to 1.3 but after 5-15 minutes of Prime 95 it blue screened with some sort of Watchdog error, it was running around 30c idle but it was getting up to 86c at some points in the test, then it would go down to about 67c and then back up, this is with a Corsair H100i GTX cooling it, with the same cooler on the 2600K at 4.4Ghz I was getting around 30c idle and 50-55c at load, so what the heck, 30c more for this and it's not even stable? eesh.

Please can someone help.
 
set everything to auto, then change the voltage to fixed 1.3V, set the strap to 125 and the multi to 34 (125*34 = 4.25ghz), test for stability and work your way up
you'll also need to check what the uncore is set to (cache multiplier) with 125 strap you can start at say 24

also don't use Prime95, these 5th gen's don't like it, use Asus RealBench

for memory you will start to need more tweaking with voltages (system agent, VIN)

Don't want to be using 1.25 for 3200. 3200 is perfectly happy on 100 strap, 1.25 may require tuning.

VCCSA (system agent) 1.05

Vcore 1.2v > 4.2 then work up or down increasing vcore / frequency.


As Angrybird says, Prime is a big no on these chips. Have seen a few users degrade them this way. This is due to the AVX 2.0 routines present in Prime, which call on more voltage. The current this test can pull can result in damaging the CPU over time, it is actually < GIMPS test > the soul reason AVX 2.0 requests more voltage. The test is barbaric and no AVX 2.0 application uses the same algorithms as Prime.

Also I've no experience with the MSI X99A Krait Edition so am unsure if this motherboard has an OC socket, if it doesn't, you'll likely struggle with those memory frequencies. (2800+)

Thanks guys going to give it a go now I'm back from work, one thing though I can't see the word strap anywhere(base clock?), same goes for cache multiplier and VCCSA.
 
Ok I've done a just over two hour stability test with AIDA64 trial version on 4.2Ghz with VCCIN Voltage at 1.9, CPU Core Voltage at 1.3, CPU Ring Voltage at 1.25, no errors or throttling detected, temps at between 50c and 60c on some of the cores with two of them between 60-70c.

Going to try 4.4Ghz on same see how it goes.

Can I assume Cache OS/Bus Ring is what is called CPU Ring Voltage on this motherboard? Or something else? I don't have a system agent setting that I can see either, I do have CPU SA Voltage Mode and CPU SA Voltage options.

OK, 2 hours of AIDA64 at 4.4Ghz fine, same temps, 1 hour of Firestrike custom maxed at 2560x1440, failed right at the end with:


Unexpected error running tests.
Workload Single init returned error message: DXGI call IDXGISwapChain::SetFullscreenState failed [-2005270494]:

The requested functionality is not supported by the device or the driver.

DXGI_ERROR_NOT_CURRENTLY_AVAILABLE



Don't know if that's a CPU OC issue or GPU Driver on Windows 10 issue, my two 980's are stock.
 
Don't run GPU tests to test CPU, but if it passed aida then the next best thing will be to run games

That error can pop up on firestrike if you have anything like GPU-Z or MSI Afterburner running and ot polls the GPU at the same time it wants to do something

Got MSI X99A Krait Edition can happily report it does 3200mhz and 4.5ghz 1.260 on a 5820k and I'm pretty sure it doesn't have OC socket.

Well looks like 4.6 isn't stable, tried 1.3 and 1.31 volts and after a few moments on the desktop I get a blue screen, tried the 125 base clock way and multiplier at 37 I think it was and that won't even get to windows, it came up saying the OC failed. Strange thing though when I put it back to the 4.5Ghz settings that worked last night it still came up saying it failed which makes no sense, I had to change it a few times till it worked again. I'm now going to let it run the AIDA64 test at 4.5Ghz again but for much longer, about 7-8 hours while I'm in work, see if that fails or not.

I would say 'fine' and 1.35v System Agent might be a bit of a white lie considering those frequencies on OC socket boards work within stock voltages (depending on the density of the kit) and 1.15v.

I only need 1.04v for 3200 C16 1T
 
Well it managed to do 8 hours just fine at 4.5Ghz, but it doesn't matter as the damn motherboard is now complaining at boot that the OC failed, even when I put the settings back to default manually it still said that at stock, reloaded in my saved 4.4Ghz and it loaded windows then, what the heck is going on.:mad:

On krait it had a setting for pre setting on different memory types, samsung, hynix etc. I just selected Hynix 3200 16 and it bumped that SA voltage automatically of course I tried to lower it but wouldn't get stable so left it at that. Ram voltages are left at stock 1.35v though.
