Failing to boot with new memory

[garypants]

Bought new memory as I just upgraded to vista 64, took out the old memory and put in the new modules in the slots recommened by the motherboard manual. Pressed the power button and it booted for 3~5seconds before restarting. Basically it will keep going On/Off/On/Off etc etc.

Tried different slots on the board still didnt work. Someone said about me needing to change settings in the BIOS like volts/timmings but im not 100%.

Hoping one of you guys here can help me out.

Any help on this would be greatly appreciated.

Thanks

Motherboard: Gigabyte GA-P35-DS3L
New Memory: OCZ 4GB (2x2GB) PC2-6400C5 Dual Channel Vista Gold Series
Old Memory: Corsair 2GB DDR2 XMS2-6400C5 TwinX (4x512MB)

Does it boot with the old ram?

 

[garypants]

Yup, Im using it now

Three things to try.

1) If your new memory is rated for 2.0/2.1V: using old memory, go into BIOS and set memory voltage higher (default is typically 1.8V). Some high performance memory won't boot if the voltage isn't set to its specified voltage. OCZ memory is (in)famous for this kind of behavior (I had one pair of DDR2-667 Gold sticks from them that only booted properly in two motherboards out of nine tested).

2) Flash your motherboard BIOS to the latest version available from the manufacturer. This will often fix memory headaches (improved compatibility).

3) Try booting with just one stick of the new memory installed.

Thanks Denithor, will try those tonight or tomorrow and get back to you.

Edit; On the screenshot I linked in the OP. It would be "DDR2 OverVoltage Control" which I would be using to increase the 1.8v to 2.0v?

Yep. Let us know how it turns out.

Been busy, but tested it last night. Anyways, boots fine with one of the modules, as soon as I put in the second module it starts the boot-cycle(constantly rebooting) no signal from the monitor. Is this what normally happens with dead modules? or could it be something else?

Probably but get the memtest86+ iso image, burn to CD (if you have system to do this) and run test on the suspected bad one. It seems you have a bad DIMM in there.

yep, one bad stick. Return both (if in a kit).

I wouldn't even bother with memtest, if you cannot boot with both sticks installed you've got a bad stick, get it RMAd before your time period runs out.
