Underclock cpu and gpu?

Hi, i'm having some problems with my new rig. When my build was new, in september, i played League of Legends and Battlefield 4 my computer froze with audio loop. None of the keys worked so i was forced to shut it down manually. This happened 2-3 times and with random BSOD's over two or three days. Then it shut down and wouldn't turn on again. I sent the motherboard and got a new one, still didn't work. Tried with new CPU and the computer started up again.

This was yesterday, and now i just had the SAME problem when playing League of legends today. The game froze and audio loop. Had to shut it down. Got "Overclocking failed!"-error message on boot.

I read that underclocking cpu and/or gpu could fix this issue(?) How exactly do i do that, what software to use? I'm new to all this, so i really appreciate all help :)

MOBO: ASUS X99-DELUXE LGA2011-v3
CPU: Intel Core i7-5820k
CPU COOLER: Phanteks PH-TC14PE
RAM: Crucial DDR4 2133MHz 16GB
GPU: ZOTAC GeForce GTX 980
PSU: SuperNOVA 750 G2
HDD: Desktop HDD 2TB 7200RPM
SSD: 840 EVO Basic 250GB
 
From BIOS (at boot press DEL) or have you installed ASUS AI Suite 3 (http://dlcdnet.asus.com/pub/ASUS/misc/utils/AISuite3_Win7-8-8-1_X99-Series_V10090.zip)

With AI Suite it should be quite simple to change clock speeds...
 
This is a very weird issue. Have you overclocked your CPU at all? This should NOT be happening @ stock and does not justify an underclock. Have you tried new sticks of RAM?

Regardless, if you still insist on underclock (Which, I repeat, should NOT be the solution - hardware is made to work well at stock speeds) you could do so by lowering the multiplier of the CPU at the BIOS. You could also try lowering the BCLK (Base Clock), but that needs a little bit more know-how since it often equals a change in memory frequency or even the CAS latency itself.

GPU is easier. Just download some sort of GPU-tweaking software (Each manufacturer has it's own - I personally use MSI Afterburner, you do NOT need to use your GPU's manufacturer software. They all work the same for all manufacturers and models) and lower the core and memory values. Do so until you find something that's stable.
 




Thank you, I found some options in AI Suite but I'm not sure what to adjust and I really don't want to make things worse.. Never overclocked before and i just got my system up and running after two months of trouble, so I'm a bit afraid 😛

I checked my BIOS version and it needed an update so i did it just now. Hope it helps..



I have never overclocked or underclocked, haven't changed any settings. I don't know if the cpu is the problem here but i've googled a bit and some people said that underclocking helped. I'm desperate here, i just want it to be stable. Not sure what to do :\ My RAM sticks are brand new, forgot to mention in the specs that i just bought Corsair Vengeance DDR4 2666MHz 16GB, which i got yesterday.

I will try to take a look in BIOS, i'm just afraid i will make this worse 😛
I downloaded MSI Afterburner, is it Core clock or Memory clock i should lower? How much should i try to lower it? Sorry about all the questions, i'm really newbie at this :\
 


I'd first try to lower just the CPU clock. Go to the BIOS and lower each of the cores multiplier value. Go slowly, until you find a value that is stable. Let's hope your BIOS update fixes it and no underclocking is needed.

Regarding the GPU underclocking (which should be done as a second option - it's far more likely the CPU is causing this issue), you may want to lower both. Make slow 5 MHz jumps backwards, until, like in the CPU, you find a value that works.

And there's no secret going into the BIOS. Take a look at a few guides or videos of your motherboard if you're uncertain where the over/underclocking options are. The problem is that several bad components can cause this kind of BSOD issue, from bad HDDs to CPUs or faulty motherboards. Don't panic if nothing I said works - you should ask the support from wherever you got your rig (or the hardware from it) for a RMA. This could even be a PSU issue.

 


From AI Suite go to TPU and drop ratio to eg. 40 (then your CPU runs max 4000MHz) you can also change graphics card clocks etc. from TPU too (Graphics cards tab from top)
 


Thank you :) Stupid question - how do i know if the value is stable, do i just have to wait and see? I will look at some guides on how to over/underclock, hopefully it will help. My motherboard and ram are new, so i have no idea how to fix this. It's a custom build rig so it's not easy to know what parts to send back :\



I saw that the ratio is at 34 and 36, I don't know what default is? Should i lower it more? Took a screenshot so you can see.

Thank you both for the help so far :)

Yep. Do your underclocking, then play a game or run your PC normally until it's stable. If it is, well, nothing will happen - meaning the computer will work as it should.

Bear in mind that it may not be a CPU-oriented problem, though. Perhaps it's even your HDD or SSD fault. Often, a problem is being caused by something that shouldn't even be considered at a first moment - such as your PSU or HDD.
 
Just a little update: Tried to set ratio to 50 (4000MHz) on the cores just to test, but computer froze and i had to shut it down. Every core is on 34 now, is it possible to lower it even more?
 


My bad, it was for my CPU... Your CPU's default clock is 3300MHz
