*Boggle* Alright I have tried everything and I am just confused, looking for advice

[OldWiseNut]

Alrighty here goes. I am running 2 gigs of CMX512 3200XLPT 400mhz ram, (4 x 512) in my Asus P4P800-E Deluxe Motherboard. I ran mem test with all 4 sticks in and got many errors on tests 4 and 5. So I started the lengthy process of testing every stick in every possible combination. I first tested all 4 sticks individually in all 4 ram slots on my board, no errors. I then proceeded to test 2 x 512 sticks in slots 1-3 no errors, I then ran the other 2 sticks through the same slots 1-3 no errors, then I repeated the processs with slots 2-4, no errors. So im scratching my head like hrrmm so I tried to run all 4 again thinking maybe the ram was just seated badly the first time and sure enough error after error after error poped up on multiple cycles. So I was like ok this is odd but I will try running 3 sticks (which sucks cause i have to run them at single channle) and sure enough no errors no matter what combination I use them in. IE slots 1,3,4 or 1,2,3 or 2,3,4 etc etc.

 

I am in desperate need of advice here, I simply do not know what else to try. I Paid for 2 gigs of rather pricey ram, I would like to be able to use all of it. Any advice would be appreciated.

 

Thanks in Advance

*edit* I also forgot to mention that 2 of the sticks are v1.1 and the other 2 are v 1.2 I also tested them in combination of v 1.1 with a 1.2 in dual channel and I had no errors so I hope thats not the problem I had no idea the sticks i bought were gonna be different versions, I bought them about a month apart from newegg.

I had a very similiar experience over the last two weeks (testing various sticks in various slots overnight).

 

I am finally convinced that its heat. My comp would usually crash during the day... then in memtest+ I would only get errors with all 4 sticks in, never with two or even three, and all sticks worked when individually tested, and in each slot also. Only with 4 sticks would it generate memtest errors, and even then, only on the 2nd pass and up during test 5.

 

When I pulled out the sticks to rearrange, I would notice how damn hot they were, but again, seemed worse when all four were packed in together.

 

By the way, I have the same mobo as you.

 

For me, I think my new "quiet" case is the problem, less airflow (it's a Lian-Li with a strange fan system, the rear case fan points in, and there's this blower fan where the PCI cards are).

 

What I finally did to convince myself: I ran memtest with all four sticks with the case open and a big home fan blowing right into the case... no errors on 3 passes.

Still looking fer help =/

Can you tell me the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set?

CPU speed is 3.0ghz HT, 800 mhz fsb, memory is clocked at the 2-2-2-5 Settings, all bios settings are defualt for the board.

With 4 modules you may need to relax the timings and I would set the Dim Voltage to 2.85 Volts as well. You might try Cass 2.5-3-3-7 and then test the system and tweak the timings from there.
