MVE memory compatible?

[WiLd_FyeR]

Is the MVE motherboard limited on what kind of ram sticks to use? Just wondering because I'm having trouble going past 4.3ghz overclock on the 3770K.

I have the Corsair Dominator 2X8 16GB 1600hz. model CMD16GX3M2A1600C9

Did memtest and passed 10 passes on default settings and XMP settings

You memory clocks are independent of your CPU clocks.

How are you trying to OC? and list all your hardware.

Based on the model number, that's a Dominator Platinum kit - it should be OK for the MVE + 3770k... actually it is as it passed the memtest 86+...

When you XMP from Ai Tuner, just start pushing the CPU multiplier... leave the Vcore at auto for the beginning, but do watch the temps... - when you reached the desired frequency, you can work on lowering the Vcore...

Make sure that both power plugs for the CPU are connected...

Thank you Zka17 for chiming in REP+

I've been overclocking using the BIOS and used the guideline on OCN.

For overclocking 4.5ghz. I've been changing the CPU PLL from 1.5 through 1.8 and can't get it to be stable. I've went throught vCore from 1.20 to 1.35 with no stability. The best voltage I've run into is at 1.23vCore that will do Prime95 for 7 hours but it has WHEA errors at 4 hours.

I also tried manual ram settings and XMP but to no avail. Will connecting the extra 4 pin power to the mobo help with stability???

MotherBoard = Maximus V Extreme
CPU = 3770k
PSU = Corsair 860i
DRAM = Corsair Dominator 2X8 16gb 1600hz

Well, the problem with those guides is that they're not made on your particular rig... every piece of hardware is different, even if the sticker on them is the same...

I've been there too... it's a big mess... Just an example: "I've been changing the CPU PLL from 1.5 through 1.8" - I don't like to touch CPU PLL until I don't have a stable OC... it's just complicating things...

So, again, your motto is K.I.S.S. (keep it stupid simple) - set back your BIOS to defaults (via F5, just double-check your SATA configuration), set XMP in Ai Tuner and start pushing your CPU multi while you're monitoring the temps... DO NOT HAVE TO CHANGE ANYTHING ELSE AT THIS PROCESS!!!

When you reached the speed you want, write down the values from the BIOS and introduce them manually... then you can start playing with the voltages... - start with the Vcore lowering by one notch and doing stability stress, then again until you find the lowest voltage for your frequency... then you can try the CPU-PLL too... and then VCCSA and VCCIO too...

One thing you have to keep in mind: the temps will define how high you can push the Vcore... do not let your CPU over 70-75C for long times!!!

And by long times, I mean "Prime95 for 7 hour" too... it's absolutely useless to force your system through that torture - unless, of course, that's your main goal, to run Prime95 for long hours... I would suggest you the ROG Real Bench, which is much faster and if your system can pass 3 times one after another it's most likely stable for everyday use... - and it's much faster too...

I see.. So everything in auto except for memory frequency and multicore? So changing other BIOS settings are just to lower the temps or stabilitiy?

I've run my 4.5ghz settings in intelburntest that passed 10 passes with 90% memory used. Not sure if that counts. I'm a bit confused with overclocking stability, some people say 12 hours of Prime95, some say 10 passes of IBT. uhhm..

If you want to do high performance overclocking, then you need to change more things in BIOS... - for your desired 4.5GHz with the memory at 1600MHz you don't need to over-complicate things...

Again, only things you need to modify at the first step are:

Ai Tuner to XMP
CPU multi to 45

Then go into OS and double-check the core temps and post them here, please.

It is like a max 5 minute process, I don't know what are you hesitating for so long... 😛

DO NOT FORGET TO RESET YOUR BIOS TO STOCK BEFORE YOU APPLY MY SUGGESTIONS!!!

Well the last couple of weeks, I've been running IntelBurntest and did the 10 passes at 4.5ghz. I don't know, I don't feel like passing Intelburntest is a legit stable overclock. I've been trying to get the golden 12 hour Prime95 stability.

I have no idea why anyone would want to cook their CPU for 10 hours or more. It simply defies logic, no normal usage of a system requires 100% on all cores for countless hours. That is not how a CPU is designed to work nor reflects day to day usage patterns.

Those kinds of tests, prime and others, have a place. I will use them for 10 minutes at a time to check the heat generation of the CPU at a particular voltage and frequency. Nothing more. Stability is not a system that has sat cooking for 10 hours, all you demonstrate is the ability to pass the test at that given moment. There are heaps of instances of folks passing 24 hours of Prime and then failing within minutes of playing WOW or watch youtube.

Stability is the capacity to do your day to day things, the purpose your PC was bought, be it gaming, movie rendering or what ever without your system failing.

Right now a very good test of real world stability is the ROG RealBench. It uses actual in use applications that we are likely to use, in a way we are likely to use - and if you can pass the benchmark then you are pretty much as stable as you need to be.

Man, the Intel Burn Test and Prime95 are just burning your CPU!

Passing even 48 hours of those tests will not mean anything regarding your system's stability! You will know that your system can do it... and now you will also know that your CPU is degrading during those tests...

Of course, if you competing in how long your system can run those stress tests at a certain clock, then it's OK...

ROG RealBench, however is much faster and gives you more real-life infos about your system... but it's your choice, which one you want to use...
