memory voltage issue

[oldtony]

Hi, I'm having a problem, have tried to find a solution myself (am sure it's out there) but I'm a bit confused now...

I'm experienced in computers but have never tried to overclock etc.

I've just built a new computer -

Motherboard: gigabyte ga-870
CPU: AMD Phenom II X6 1090T
Memory: Mushkin 4GB (2x2GB) DDR3 PC3-12800 6-8-6-24 Radioactive 1.65v
Radeon 4870

My motherboard said it supported 1866(OC) / 1333 / 1066 MHz memory.

I ended up buying the memory above as I read that it would work fine at 1333mhz, also that I had the ability to overclock if I ever wanted to. In the past I've just bought the best memory that the mobo supports, this is the 1st time it's been a bit confusing (with the 1866(OC) being why I didn't just buy 1333 memory). I didn't think about the voltages etc...

Weirdly, the system will crash, randomly, a couple of times each morning (bsod - bad pool header) then it will run the rest of the day perfectly - it seems after it's warmed up?

I looked at my bios and the memory is running at 1333mhz and at 1.5v

Could this be why the system is unstable?

Should I raise the voltage to 1.65v as that's what the memory is designed to be run at? (to be exact I can only set 1.64 or 1.66) If I do, should I also run the memory at 1600mhz?

Also if I do either of these things (raise voltage and/or memory clock speed) do I have to change any other settings (ie with cpu or memory timings)? or can I leave them on "auto"?

Any help would be greatly appreciated.

Thanks in advance.

Tony.

Set the memory to it's rated voltage. 1.66v will be fine. The memory is designed to be run at 1600mhz so I cannt see any reason to underclock it to 1333mhz. Just set it up like it says on the specs and this should eradicate your BSOD problems.

Setup the the ram as recommended, you should not need to adjust the cpu speed or voltage.

Try the memory with 1.64v.

Thanks for your help. I'll change the memory settings and see how I get on.
