I wrote this in the Ask 8 Pack section. But realised it should probably be here instead.

So I finally set up the new PC yesterday. Here are the specs:

Mobo: MSI X99A SLI Plus
CPU: Intel Core i7 5820K
Cooler: Corsair H100i GTX 240mm
RAM: Team Group 16GB DDR4 2400MHz (4x4 sticks)
GPU: Sapphire R9 295x2
Storage: 3x SSDs (120GB, 500GB and 1TB)
Sound: Creative SB Z
Case: Zalman H1 Full Tower Case
PSU: OCZ ZX Series 1250W Fully modular PSU

At the moment it's all running on stock. I did try to do some quick basic overclock (not using the turbo feature) and each time the system wouldn't boot or would crash before getting into Windows.

I just need someone to give me some step-by-step guide on how to overclock this badboy. What settings do I use, what not to touch, etc. I have had a look online and while no one uses this particular board, there's no clear cut explanation (that I can understand anyway) on how to overclock the CPU. Visual guides would be handy so I can see exactly what needs to be done!

Bear in mind, it has been a good 6 and a half years since I last did any proper overclocking. Given that I was on an Intel Core i7 920 D0 for that long!

Thanks for the help peeps! :)

PS. I am currently at work so won't be able to do some testing until later this evening!
 
good luck!, been trying for 3days to get my 5820k 4.4ghz stable on msi x99a mpower. this has to be the most difficult platform i've tried to get stable :/

What settings did you use? I just need to know what to use in order to kick things off.
 
im 2 hours in to prime95 testing vcore, im using 100 x 44, 1.29vcore, 1.2v cache(vring), 1.95v input voltage, 1.2v SA voltage, 1.35 dram voltage ram is running at 2666mhz everything else is left on auto.

i've also left cache at 3000mhz until i get the vcore/input voltage stable.

this thing gets toasty in prime95 you need a serious cooling setup to keep it in check!

I won't be using prim95. Lol. I will give AIda64 a try. Just upped it to 4GHz on 1.25v leaving everything else on auto. Will see how it goes.

im old skool, to me a system isnt stable if it doesnt run prime95 for days :P, im starting to get some where now tho this is the most stable the machine has been, i was previously trying for 4.5ghz but was finding it difficult to pin down what voltage was causing bsod

I will give prim95 a shot then. See if it really is stable even on 4GHz. Lol.
 
i wouldnt recommend using small ffts, it makes the cpu way to hot. im using these custom instruction to test certain voltages... you might find them useful

1344K = Vcore . -> at least 30min selectively, with some chips is to test the Vcore after 60-90min
448K = Vrin / Input -> once passed ranges Custom, provided the cache Voltage is true. 512 u.
576k cache = / Uncore -> at least 30min selectively, usually ranging max. 60min 576k.
672-720K = VTT -> at least 30min selectively, longer for deeper knowledge, max. 90min. =
768K Agent / IMC -> at least 30min selectively, longer for deeper knowledge, max. 90min.
VDIMM = 800K / timing -> at least 30min selectively, longer for deeper knowledge, max. 60min. = 864K play here all the components inside . -> at least 60-90min selectively During selective testing, the relevant FFTs / K values ??individually before you take that then in the loop run every 15 minutes passed until one breaks or errors occur . The custom-Run will start with the default settings of 8-4096K Run FFTs in-place in order, as further set forth in

What was the bsod code vonex. Ill keep an eye on this thread as im hopefully soon moving to a very similair setup.

Awesome. Many thanks! :)
 
Mmm, i know that 101 is vcore, but 124 can either be vcore or sa/io. Going by my experience on standard haswell.

i've just passed 2hours20 on testing vcore, testing SA now.. it crashed with in 5minutes so ive just set SA voltage to 1.25 from 1.2v.... retesting now

EDIT - been running prime95(768K Agent / IMC) for 32mins since upping the SA voltage to 1.25

Got mine upto 4.5GHz. Just changed the Vcore to 1.29 and the CPU Ratio to 45. While I haven't exactly ran prim95 or Aida64, so far, no blue screens. Temps are at a rather warm mid 40s. But I am putting that down to my room being rather toasty. Even my other PC (which I am typing from) is showing roughly the same temps.
 
running at 4.4ghz ram is set to XMP 3000mhz, cache is default(3000mhz) and its passing all tests im chucking at it

125 x 35
vccin @ 1.95
vcore 1.3
SA - auto (memory xmp)
VCCIO - auto
everything else on auto
 
Good to know others have this board too. I've got the same CPU and board (and H100i GTX) and haven't yet got round to playing with the overclocking side so I'll be keeping tabs on this thread :)

Very good. I will have a bit more of a tweak with mine later this week and see if I can achieve the same. I have since dropped it down to 4.2GHz and dropped the VCore to 1.1v. Would you mind posting screenshots from the BIOS as well please? It would definitely help. If you don't mind. :)
