extra ram causing system instability

iToke · 15 Sep 2011 at 08:44

Hi guys,
I have an overclocked i5 750 PC (running @ 3.36ghz) with 4GB (2x2GB) of corsair XMS CMX4GX3M2A1600C9 memory running at 1600mhz instead of 1333mhz.

I just bought another 4GB corsair kit (exactly the same) to give me 8GB total ram. When I added the extra ram my system became very unstable, BSOD's, failed boot attempts etc.

Not sure what I have to do to make my system stable. I have a great power supply (800w OCZ extreme), a corsair H50 water cooling kit on a Gigabyte P55 UD4 motherboard. I've updated the BIOS to the latest version and I'm using Win7 64bit SP 1

any thoughts?

thanks

try backing off your overclock / increasing ram volts (not over the maximim)

or maybe slacken the ram a notch or two

Thanks for the quick reply, I'm new to overclocking (my first attempt) how do I know what the max ram volts are?

Thanks again SupermotoMX.
I've uploaded an Everest report of my overclock & memory details here

If the only way of having 8GB of ram instead of 4 means I have to return all my BIOS settings to standard i.e not overclocked, what would be better - an overclocked PC with 4GB of ram or not overclocked but with 8GB of ram?

I mainly use my PC for web development, so I often have Dreamweaver, Photoshop, Illustrator & web server software open at the same time and I also use it for gaming & watching HD movies.

If I get things wrong, can I cause serious damage?

Cheers

Just checked my BIOS, the ram voltage is set to auto (1.5) will have a go a tweaking it later when I've got time.
Thanks for all your help.

Thanks Plec, just downloaded Memtest.
Will post my results later.

Great forum by the way, nice to have quick, knowledgeable replies!
