new ram works with 2 sticks in and not 4 ??

James Manns · 22 Dec 2011 at 17:49

hi there,
just bought a set of kingston 16gb hyperx from this weeks only and when i put all 4 in i get blue screen of death after about 5 minutes or when i do anything taxing, i took 2 out from slot 2 and 4 and everything works fine, so ive just done memtest and it passed with no errors..???

can anyone help me sort this out ??

thanks in advance, James

Motherboard? Overclocking anything etc?

SeraphX · 22 Dec 2011 at 18:25

what are your system specs? is your processor running overclocked at all? what was the old ram you used,

James Manns · 22 Dec 2011 at 18:57

nothings overclocked,

my system specs:
mobo: gigabyte p55a-ud3
cpu: i3 2.93ghz
new ram: Kingston HyperX Genesis 16GB (4x4GB) DDR3 PC3-12800C9 1600MHz Dual/Quad Channel Kit
gfx: ati radeon HD 4850
old ram: corsair xms3 1333mhz

ive change the frequency profile to "profile1" which is 1600mhz to match the new ram but that hasnt worked, not sure if theres something i need to do to enable dual or quad channel ??
thanks for the help

you can't get quad channel on 1556 and it would allready be running in dual channel so it wouldn't be that.

ooh ok, any ideas why it won't work with 4, tried so many combinations and settings

Mr Gimp · 22 Dec 2011 at 19:16

Is this the first time you've populated all four slots?
I know this sounds retarded, but it might be worth checking if you have a pin misaligned on your motherboard in the CPU socket, as I had that problem earlier this year with a new build I was doing, and this was the culprit!

To clarify, it works with just the two sticks, but does it work with the other two as well?

James Manns · 22 Dec 2011 at 19:24

ill check that if nothing else works as i would have to take the mobo out,

and yes it all works fine with 2 but with for it either gets bsod after about 5 minutes or fails to boot os

try 1 stick at at time mate. could be the slots on the board, but more than likely the ram, 1 of my sticks has gone faulty this week and i sent a set back to corsair in holland. To find out which it was for me i tried 1 set and then the other, was easy to find the bad set.

Set your voltages for the memory a tad higher, maybe one or two notches up.

+1
Vcore and vmem up a notch or two, it may be the memory controller on the CPU

James Manns · 23 Dec 2011 at 11:51

ill try and see if its just one,

the voltages are set at the ones given in the item description ??

Test Voltage: 1.50-1.65V

It varies. Also, each board is different and may require some tweaking, especially when all slots are occupied with big modules. Whatever it set it self to, try slightly higher.

James Manns · 23 Dec 2011 at 13:02

ok thanks, ill give it a go,
also will one stick work in any slot so i can see if one of the slots or ram is faulty ??

James Manns · 23 Dec 2011 at 13:14

what should system memory multiplier SPD be set at ??

and there is no option to change vmem voltage but there is DRAM which is at 1.500v ??

thanks

Leeroy123 · 23 Dec 2011 at 14:36

dram is the memory voltage, if its at 1.5 try 1.55 or something, but also try each stick on there own.

James Manns · 23 Dec 2011 at 18:58

right, tried all of the voltage changes, didnt help, so ive taken the two out which i think one is faulty and tried the two working ones in slots 2 and 4 to see if it was the sockets but it seems to be all ok so ill work out now which of the two sticks i took out is faulty

James Manns · 23 Dec 2011 at 19:25

turns out all sticks work ok, its just when i put 4 in it wont work..?
any ideas why it wont work with all 16gb ??

thanks

Have you over tightened your cooler? That can cause ram issues.

Failing that, try updating your BIOS to the newest version and/or continue to tinker with suggested volts.
