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 :daisy: 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 (http://www.gigabyte.com.tw/FileList/MemorySupport/mb_memory_ga-p55-ud6.pdf)?

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.

Antec ATX TruePower 750W Blue


apart from that, I'm running:

Western Digital 500G SATAII 7200rpm HDD 32M Green Power (times 2)
Pioneer SATA DVR218L 22X DVD Black & Cyberlink

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.

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 (http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=140) seems to rate it though.

Here (http://www.memtest.org/#downiso) 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.
