The CPU was @ 5.0Ghz CPU/NB and HT Link @ 2600Mhz ( I never run the HT Link higher than the CPU it can cause instability) The CPU/NB voltage was 1.4v with the LLC on regular.
So, the basic thing here to get CPU/NB to 2600 MHz is give CPU/NB even more voltage - like you wrote 1.4 V (regular? and what about CPU/NB current capability? Did you set it higher to let's say 110 % ? )
I'm currently running tests on the tridents so far it's @ 2218Mhz 9-11-11-31-2T @ 1.65v CPU/NB and HT are @ 2704Ghz. I'm using Win 8 Pro O/S. That kit should work fine I'm basically running the Tridents the same at the moment with slightly different timings.
I'll have to test your settings (maybe I will lower down CR from 1T to 2T. It shouldn't have much impact at performance - I guess).
Right! Thanks for your help
Now it's time to get through this "painfull" OC process

I haven't changed anything in the bios before so please can someone help me.
Do I just change the 9-9-9 to 8-8-8 ?
So, it is not so easy as it looks like, but you'll have to check this guide AMD FX Processors Unleashed | a Guide to Performance Tuning with AMD OverDrive and the new AMD FX Processors
. Read it carefully and if you are not sure just ask a question here and I am sure someone will answer you. But first - read the guide. Very usefull in my opinion.

Hmm. First of all if you want to overclock your ram without touching HTRefClock (or CPU Bus/Peg Frequency) you'll have to select proper divider in BIOS menu. It also depends what kind of CPU you have. For instance Deneb and Thuban CPU doesn't see a divider for 1866 in BIOS. It changes only when you have FX (Bulldozer / Piledriver) CPU.
Remember. Higher speed needs higher voltage. Tighter timings also. I just don't know what are your correct timings for your MemSticks. And if you start to overclock your processor using HTRefClck it is natural that you will have to rise your memory voltage (probably to 1.65 V - check your manual) and CPU/NB Voltage but that depends (as I said) on the kind of CPU you have (Deneb, Thuban or FX). That's all. Before you make any changes it's good to ask because you could damage your CPU or MOBO.
