Thanks for the replys, the help is much appreciated!
Sorry to be a pain but if we/I don't a ask and we miss a memory problem ..... it can go in very BIG circles .... " Ive confirmed it not the RAM"
..... So you tested each
Dimm with memtest86 for ten passes each in your boards slot 1 ....Right?
Time spent here can save you days smacking your forehead on the screen ..... You may be right about 3_5 and an RMA but let's hit this the right way from the get-go and rule out all the other things it MIGHT
P.S ....Plenty of time.....your boards got 3 yrs of warranty.
I did it by swapping the RAM sticks, any of the 3 will work in the DDR3_1 and DDR3_3 slots.
Im burning memtest86 now, I will follow your advice and post the results.
Please can you give a brief run down of your system hardware.

Are you sure that the full 6GB originally was available ?
If so I think that the next step would be to check the CPU socket for bent/burnt pins.
Take all the usual anti-static precautions.
Very carefully remove the heatsink and fan. Probably a slight twisting motion is best to release the two as the thermal paste can act like a glue.
Once off remove the CPU taking extreme care both physically and electrically(static) and place somewhere safe.
Make sure that the lighting is very good and even.
Now scrutinise the socket for any pins that are out of alignment, even slightly.
If in any doubt whatsoever take a couple of macro (close up) photos of the socket and post them on here for us to check.
Also look at the bottom of the CPU at the lands (little copper circles) and make sure that there is a mark in each somewhere near the centre.
If there are any missing marks or any of the pins are obviously bent then that is your problem.
Before refitting the CPU clean off all residue of the old thermal paste and the same on the heatsink and then apply a small amount (about the size of a grain of rice) to the centre of the CPU once it is inserted in the socket.
Im positive the full 6GB was available, it was showing on both the post screen and in windows.
I will take a look at the CPU but im doubtfull as it was previously working, I havent touched the CPU or the heatsink. Its exactly how overclockers installed it. I will test the memory first then check the CPU. I need to order some themal paste so I might take a day or two to post the results.
