My Asus Sabertooth used to be fine with my 3 x1gb kit. However reinstalled windows (Win 7 64bit) and now I only get it to recognise 2 or 1 gb of ram. Any idea how to test to prove if board or memory faulty? This board is a new one as last one was RMAed as GFX socket didnt work.

Hi there, I would suggest installing just one stick at a time in the A1 slot and try and run Memtest. If one stick fails the you have found your problem.
Also, if you are looking to go for more RAM, this kit is a cracking deal today (6GB for £29.99).

You are correct to wonder about overclocking, as with these boards you need to increase the BCLK (which in turn raises the memory fequency as well as CPU frequency) and ideally you want to run the RAM at stock clockspeeds (1333MHz in this case) as that is what its rated to.
However, the memory has a multiplier separate to the CPU multi - so you can set memory speeds independently as you increase the BCLK. This means that even when the CPU is overclocked you can keep the RAM at or below its rated frequency (so long as you are offered a low enough minimum memory multiplier).
I'm not sure what the minimum memory multiplier for the sabertooth X58 board is, but you can check by going into the BIOS and seeing what the lowest "DRAM Frequency" you are able to chose when at the stock 133MHz BCLK (this option can be found in the "AI Tweaker" part of the BIOS).

Ok Current memory is Geil 3gb 3x1gb 1333mhz 9-9-9-24 at 1.5v.
Each stick passes memory test 1 at a time in slot 1.
Take 1 stick and try in each slot and all slots are fine.
Boot into windows with all 3 sticks and I get either 1 or 2gb showing in windows. WTF?
Any ideas? I do only run mem test 4.0 for 10 min which is 1 pass and 0 errors.

2 passes with all 3 gb in and all good so far!
The voltage for ram is rated at 1.5V. However the Sabertooth shows
QPI/DRAM Core Voltage
DRAM Bus Voltage
Do i just change the bus voltage to 1.5v and leave qpi on auto? What is QPI core voltage? Leave on auto forever?
