Overclocking impossible and booting issues.

[Cheerscake]

Hey guys,

 

I'm having some issues with my system but I can not tell which part causes the issues.

Basically there are two problems. The first one is the fact that it is not able to maintain its overclock (Even only 100Mhz). No matter wether I do the canges in the BIOS or through AMD Overdrive or the ASUS AI Suite, after turning the computer of it requires multiple attempts to turn it back on again which already introduces the second problem. It turns on for a few seconds, the fans spin, nothing appears on screen, and it turns itself right back off. After multiple attempts then it works but the following message is displayed: "Overclocking failed... Press F1 to enter setup". So then I enter the setup, set the BIOS back to default and now at least I don't get the overclocking failed message anymore. However I still have issues booting into Windows - at least on the first booting process after reseting the bios. It turns on for a couple of seconds, then turns itself off again. After that however it boots in a stable way and the issue doesn't occur anymore.

For my understanding there can be multiple parts causing the issue. The CPU, the motherboard and the PSU. Here's a list of the parts I use:

 

CPU - FX-8350 (maybe a year old), cooled by a Corsair H100i

Motherboard - ASUS Sabertooth 990FX R2.0 (pretty new)

PSU - Corsair TX750 (a couple of years old - the power should theoretically be enough but maybe it's broken or... something)

Gigabyte Windforce GTX 780Ti

16Gb of Corsair Vengeance 1600Mhz DDR3 RAM

1 Samsung 840Evo 250Gb

2 1TB HDDs

 

Unfortuantely I don't have a spare powersupply that is powerfull enought to put in there and even though I have an old AM3+ 6Core somewhere if possible I would like to avoid switching CPUs...

 

Does anyone of you have any idea towards what kind of failiure those sympthoms could point? I'm relatively desperate on this right now to be honest....

 

Really appreciate any kind of idea thx in advance guys!

You might have gotten the worst overclocker of the century. It can happen, with overclock it's pretty much luck of the draw. You could attempt to heavily underclock the 780ti to see if the power this frees up makes any difference but I doubt it. If everything works fine with no oc the motherboard is almost certainly not the issue.

Damn that's an unbalanced build.

 

I have nothing else to contribute. I am sorry that you are experiencing problems and I hope you get it resolved.

You might want to run memtest86. I had similar issues with my FX 8350 a little while ago where my overclocks wouldn't stick anymore and things just generally weren't working correctly. Turns out one of my ram sticks died on me. Just might be worth checking to be safe.

Thx for all those quick replies!

On the first point... I know that one can have extremly bad luck with processors but I kinda have a hard time believing that no stable overclock is possible at all... or rather I can believe it but I don't want to.

So now I'm indeed running memtest86+ let's see what it's gonna tell. 

 

UPDATE: First pass of Memtest done. No errors reported. However it says RAM: 652Mhz (DDR3-1305). Considering that all the sticks actually support frequencies of up to 1600Mhz I am not sure if there is something suspicious going on with that.
