RAM issue

[pevergreen]

Hi:

For some reason, when all 6 sticks of ram are in my mobo, windows hangs on the loading screen where the bars go accross the bottom under the logo. 4 sticks work fine.

Windows xp 64 bit.

Are all the sticks of RAM the same speed and type? Are all the slots the same speed and type? (On my motherboard i have 4 slots for 1 type of RAM and 2 slots for another...)

Can you enter the BIOS screen (Setup)? If so, is it registering the correct memory details (size, speed, type...)?

6 identical sticks. Purchased as two 3packs.

Two of these:
G Skill 6G(3x2G) DDR3 PC10666 9-9-9-24

Motherboard:
Gigabyte GA-P55-UD6 P55 DDR3 PCI-Ex16 SATAII RAID 2xGLAN SLI Crossfire.


Recently upon login, it bluescreens, reboots, then it works fine. Happens every time without fail now. No idea what the is causing it.

Checking against mobo manual, two operating lights next to memory are for working indicating, two for alerts (over?power and something. all 4 are on with 4 sticks, but it works, apart from that initial BSOD, go down to 2 sticks and the alerts go.

Couldnt be a power thing could it?

Could be, what PSU do you have?

Also, have you checked the RAM is on this list?

Your board's spec lists the following:

Memory:
6 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory
Dual channel memory architecture
Support for DDR3 2600+/2200/1600/1333/1066/800 MHz memory modules
Support for non-ECC memory modules
Support for Extreme Memory Profile (XMP) memory modules

But nothing jumps out at me from that.

Return the RAM modules. If anything else is viable, I'll cancel my Dragon Age Origins order (which I'd not really believe if I were you)

Really?

There doesnt seem to anything actually wrong with them.

Switching them out and they all work.

[al Roumi]

The following is listed under the P55-UD6 DDR3 1333 mobo

"2GB G.SKILL F3-10666CL8D-4GBHK DS v v"

They both look like a match for your setup.

I don't know much about Antec PSUs, trying to find a review. This one seems to rate it though.

Here are bootable ISO's for MEmtest86+ v4.00. Test your sticks with it. I'm pretty sure you'll end up seeing that you have unfortunately bought malfunctioning modules from manufacture.
