PC not accepting higher memory

[ViperZS]

Hi all,

For a while now my PC has refused to accept anything more than 4GB RAM. I am using Kingston HyperX DDR2 8500 CL5 in 2gb sticks.

Everything is fine with 4GB in but as soon as I try to use 8GB the PC just won't turn on. It doesn't seem to be any particular stick as they all work fine on their own!

Motherboard is a gigabyte P35 DS3R which can support 8GB and I use W7 64

Can anyone help me get the 8gb working?

The last time I tried to update the BIOS it said it wasn't compatible with W7 64. I'll check again though.

EDIT: Just downloaded the latest BIOS and it still says it's not compatible with 64bit

Don't update the BIOS through Windows, do it via Q-Flash. Stick the BIOS file on a pendrive, then reboot and press the "End" button on your keyboard during post (see page 68 of your motherboard manual). This will enter Q-Flash, and is a much safer way to update the BIOS.

Thank you, I'll try that!!

dodgy slot?

Nope, I've tried single sticks in all the slots

All sorted now, thank you to Orcvader for the help with how to get the BIOS update done!!!
