I am trying to get my RAM stable but having a few issues.

I am a bit unsure about the GTL refs etc which I am sure is my issue..however not knowing too much about them I am unsure what to change to try to get stable.

I have been able to run memtest no worries at these settings @ 1350Mhz.

As this ram is rated at 1800 i would have thought I would be stable at 1441Mhz but fail memtest within 10 mins everytime. Again in need of more tweaking which it where yu guys come in


I have the CPU running at stock as I have dropped the multi to keep that out of the picture -and have run Intel Burn test and Prime and the CPU is stable.


Where should I start?
I have a theory, those Corsair are probably Samsung IC and RE donīt like Samsung at all, I have similary problem with my 2x2 Trencend, I having a hard time to get them to work with my Q9650 @ FSB 450, ram @ 1800MHz CAS 8 2N but with FSB 400, ram @ 1600MHz CAS 7 1N (even though they are dubble sided 1N seems to work) they seems to work alright.

I work with 1104 right know and I have not tried 1201 yet.

But try this setup and see if it works.
