System instable since new RAM

[jonnyfgm]

I've had my system running for a long time now on a 960, OC to 4 GHz (200x20)

With this I had 3 x 2GB Kingston Hyper X 1.65V (9-9-9-27 i think)

I bought a while back for a friend 2 x 4GB Mushkin Blackline 9-9-9-24 1.5V for a rig he was planning, in the end he never ended up building it though.

So I was doing some video editing and the 6GB just wasn't cutting it so I popped the 8 GB in instead. It was fine for video editing, and for some gaming after, however after a few mins of folding the system was freezing up.

So what do we think is the cause of this? I havent changed the RAM voltage or timings, but they are set higher and looser than rated so this shouldn't be a problem right?

I think its because its now running in dual channel mode instead of triple as before, thoughts?

i would consider resetting the bios to default to see if it works at default to isolate any timing / voltage issues

if that fails, try one stick at a time to rule out a faulty stick?

 

[tinytomlogan]

Is it running at 1600mhz or 2000?

 

[Pr3d4t0r]

try underclocking i first or overvolt which ever,

if that doesnt work take two dims out to force dual chanell and then stick the other two back in

 

[jonnyfgm]

RAM is running at 1600 MHZ, also I know both sticks are fine as i tested em when i got em.

Might try the BIOS reset, but if it does work doesnt answer whether running in dual channel rather than triple makes OCing less stable

 

[demonking]

isn't the x58 platform supposed to use triple channel memory?

 

[jonnyfgm]

yes it is, but i thought you could run it in dual channel mode without too many problems.

Am i best off just buying another 4gb stick?

well i decided to buy another 4gb stick in the end, hell you can never have too much RAM lying about

 

[jonnyfgm]

so i bought another 4gb stick, fitted it, put the voltage down to 1.5, knocked the CAS timings down to 9-9-9-24, and it froze on me again

I bought the same brand, model, timing and voltage of RAM, just didn't obviously get it as part of a triple channel kit, it should work fine right?

 

[Master&Puppet]

Was it working before you played with the timings?

 

[Rastalovich]

Take your bios back to basics.

 

[jonnyfgm]

i didnt try it before playing with the timings, but i didn't really play with them, just set them to what they're rated to.

And I think I may have to wipe my BIOS and start the whole OC process again

 

[jonnyfgm]

well i've reset my BIOS, and the system is at stock.

I'm now in the process of overclocking again, I have got it linx stable, but not prime95 stable, looks like im going to have to go at least 2-3 voltage notches over what it was before. I know adding more sticks of RAM can decrease overclocking capability but can the same number of more dense sticks also cause this/

 

[jonnyfgm]

so i've got things to a 24/7 stable OC, problem is i need nearly an extra whole 0.1V of VCore to get there, does this seem normal?

Its not that bad so dont worry about it as long as its all fine ;]
