OK can you read this and see if it makes sense.

Took delivery on Friday of a new Ultima OC 9800GTX SLI 4 Gig and I have to say what a NICE bit of kit.

Unpacked it and started to install Vista Business 64 bit, which kept falling over at the end of the installation. So I re flashed the Bios on the EVGA nForce 790 Ultra to version P4 and set the mother board to it’s defaults. Vista then installed but was plagued by occasional blue screens and error messages such as super fetch and IE stopping. It also refused to upgrade to SP1 and I had a digital locker upgrade to Vista Ultimate that also refused to install.

Memory, I decided it just has to be . So I ran the basic vista memory checker that said no problems found. I re ran it and it said there were problems. Hmmmmmm :confused:

Removed all but one stick and with that I could install SP1. Ok so one of the 3 left has to be dud so I ran MemTest86 on each of the sticks and all passed :) Reinstalled all the sticks and Vista ran better but still not 100% as it still had the occasional blue screen and errors but now the crysis benchmarks would run with only one crash.

It’s now been left running at home doing 5 passes of the extended Vista memory check. So I am trying to narrow it down to one stick or a maybe a faulty MB.

Can anybody suggest anything else to try? I would much rather RMA 1 stick of DDR3 than the whole system.

Cheers
 
Could it be that my problem is caused by the memory needing 1.8V and the MB only supplying 1.5 V as that's the stock voltage?
 
How much memory do you have in your system? And how many sticks is it on? Will Vista run fine with only one or two sticks installed? There is a patch that I had to install when running 4x1GB sticks on Vista because it kept on crashing. The link for that is below:

If that doesn't work, try altering the RAM voltage. If it says it requires between 1.8-1.9v, for example, set the voltage at that amount.
 
Thanks nicktay that's good advice about the patch. I have 4 x 1 Gig and it's all getting a bit hit and miss with the errors. As I put in my original post I have set the MB back to defaults and i seem to think that that sets the memory voltage to 1.5v and i have just read that memory should be set to 1.8V so i am guessing that could be a factor.

More investigation needed me thinks.
