Win8.1 rebooting after ram upgrade.

Hi guys

A long time ago I purchased the ocuk argon i3 overclocked bundle.This has been working very well so I decided to upgrade the memory from 4gb to 8gb.

It was fitted with Corsair XMS 4GB DDR3 PC3-12800C9 1600Mhz dual channel kit,so I ordered exactly the same memory apart from 2x4GB instead of 2x2GB.

The machine starts up no problem the bios shows the memory fine but win 8.1 just keeps rebooting,I have put the old ram back in and it starts up no problem.

ocuk pre overclocked the bundle from 3.2 upto 4.2 which it runs fine with no problems at all so I am not too sure what settings will be needed to be changed for this ram to work.

Any ideas what I need to do please ?

what motherboard? latest bios?

EDIT: don't update the bios yet as it will lose your oc settings

Hi mate it is a Gigabyte GA-H55M-UD2H

I have checked and no it is not the latest bios,if I update the bios will I lose the overclock ?

Many thanks for your help.

yes you'll lose it,unless you take pics of every bios page/setting

cant you get into bios at all? with working ram boot into bios and look to see howmuch qpi/vtt voltage is set

you might need more idk

can also try booting with just one ram stick of the new ram installed,see if it boots

Yes I can get into the bios no problem but when you exit out and and start windows you get to the first win 8 loading screen,it says there your PC ran into a problem and restarts.

I tried installing 1 stick which caused the bios to go wobbly and now I have lost the overclock,so I may try and update the bios and see if that cures it.

When ocuk overclocked it they saved it to the CMOS which I have loaded back in and it seems to be working with my old memory again.

ahh ok,try this first try with 1.35v qpi/vtt

idk how much is being used atm?

I have a 540 @4.2ghz with 8gb ram and that's what im using

shaddy666 · 1 May 2014 at 18:36

I have checked in the bios and the QPI/Vtt voltage is set to auto.

Many thanks for helping

wazza300 · 1 May 2014 at 18:37

try with manual of 1.35v it might be applying too much or not enough

more ram and faster speed needs more qpi/vtt voltage usually

shaddy666 · 1 May 2014 at 18:41

I have tried 1.35 and it still keeps rebooting.

wazza300 · 1 May 2014 at 18:47

ahh ok,you might need 1.36-1.38v

if its still rebooting then id try latest bios,but copy all your bios settings and each bios page first,so that you can re enter tham after updating the bios

shaddy666 · 1 May 2014 at 18:49

Okay mate thank you will try the voltages first and then at some point will try updating the bios and see if that works.

shaddy666 · 1 May 2014 at 19:29

Just an update I have tried setting 1.370v and 1.390v and it still reboots so will have to try a BIOS update at some point.
