Hello.

I just setup a new system. The system specs are:
Intel Core 2 Duo E6750
2x1gb OCZ PC2 6400 OCZ2P800R22GK
ASUS P5K AiLifestyle Series iP35
Sapphire HD 2600XT 256MB GDDR3
Coolermaster IGreen 500W PSU

I first noticed a problem with the setup when I began installing Vista, kept getting a blue screen. I removed one memory module to test if it would work... No problems, worked perfect and installed fine.

I then thought I would test the memory...

Windows Memory Diagnostics:

Individually each stick passes again and again and again.
Together it hangs at different places each time... usually on Stride6 test. However has also failed on WINVC test and INVC test.

One time I got the following error message come up:

TRAP 0000006 EXCEPTION tr=0028 cr0=

I cannot work out why it works with one module but not both... I have tested both idividually and both together individually both seem to work... together they hang on memory diagnostics every single time.

Thanks for any help and assistance on this matter!

If the motherboard is setup for dual channel mode for the memory and the sticks aren't matched it will cause a problem. Check your memory settings in the bios.

The memory sticks are exactly the same and were bought as paired modules.

The motherboard has 4 memory slots.

a1, a2, b1, b2

It recommends using either a1 or b1 for a single memory stick
a1 and b1 for two memory sticks <- this is the setup I am using. Both with identical memory sticks.

Dachew may have some other suggestions on this one. He seems to be the memory expert here on the forums. Have you tried Memtest ?

If both sticks work individually, but cause problems when used in pairs, you might have a bad memory slot.

Wow I totally missed that option :thumbsup: . Have you tried the ram in different slots? I am assuming when you use only one stick they work in slot 1 try different slot combinations, and if the board is new exchange it for a new one.


Edit: sometimes it just takes a fresh pair of eyes.

Just wanted your opinion on the following. I have ran Memtest86 again. This time with both memory sticks individually in Slot 1.

Memory Stick 1:
Computer Froze at 4:20 on Test 5 (Block Move) every single time (about 10 times) Three of those times it displayed an error message: "Unexpected Interup Halting, Type: INV_Op" Also came up with about 400,000 errors before I rebooted the system.

Memory Stick 2:
Test has passed twice in a row been running for an hour now with no errors or anything

--

Would it be fair to say that Memory Stick 1 is "Faulty", should I ask for a replacement just yet?

It would be a fair assumption that the stick is bad I would ask for a replacement.

If the memory test freezes on one stick and not on the other - I'd say it was safe to assume that that stick was bad.

I'd return it for new RAM, citing the failed MemTest as evidence that it's defective.

Just wanted to thank you for your help. eBuyer tested the memory modules and found them to be faulty. I recieved the replacement pair yesterday and ran Memtest-86 with both of them in for 8 hours and no problems what so ever. Seems it definately was faulty ram and now my pc is all up and running brilliantly.

Thanks for all your help!! :D
