Lanparty UT SLI Expert and memory problem

[obiwan05]

Hoping someone can help me. Been happy with the lanparty mb with my 1gb dimm. Converting the system into my home server and tried to add 3*512 sticks of ram. All sticks at ddr400, but I cannot get the system to post!

It will post with my 1gb dim (kingston value)
It will post with my 512mb (ultra value)
It will post with my 2 512mb (no name)

Any combination of the above and it will not post

The 3*512mb (have not tried with the 1gb) all work fine together in my ASUS mb with a 3200+.

I have tried setting the DRAM freq to 166mhz (ddr333) as all of the dims are double sided, but same.

Any suggestions?

Hello obiwan05, and welcome to nForcersHQ.

Boy, I wish ya all the luck. What you're attempting will most likely prove to be a no go, but let's give 'er a shot ......



What is the SPD(default timings) programmed for on each of your 1Gb, KVR, Ultra Value, and no name?

Thanks!

I will get all that info when I get home tonight and post.

I am assuming that the LanParty UTs are very picky with memory then?

My ASUS doesnt appear to be picky....only chip I didnt try in there was the 1gb, but the 3*512s all played nicely together

Okay, finally was able to play:

1GB timings are 3-3-8-3
512 Ultra timings are 2.5-3-8-3
512 generics are 3-4-8-4

I did try to disable CPC (goes to 2T from 1T) but same problem... any suggestions?

[wardog]

With four sticks the Command Rate will need to be set at 2T.

Try setting your mem timings in the BIOS manually to : 3 - 3 - 8 - 3. Your 1Gb and Ultra should boot at this. It's the two generics that may offer a problem.

Give it a go at 3-3-8-3 and ...............

Hold on here a sec. Let me think if you can populate 1x1Gb and 3x512Mb?

... .. .

Ok, try this. Setting 2T and 3-3-8-3 put the 1Gb in DDR1(Channel A) and your two generics in DDR3(Channel B) and DDR4(Channel B).

Edit: To those that might be reading this. Yes, I know 2T isn't needed for three sticks. I'm hoping 2T will accomodate for the differences in timings between the sticks and at least allow it to boot.

Okay, thanks, I will give that a try when I get home tonight.

For the record, I was able to boot my 64-3200+ Asus A8N-VM SCM system without problem.

Well thanks for the help guys but I have finally given up

Following all the suggestions here and other places I've read, the best I could do was 1.5GB total out of the ram I have.

1GB in A + Ultra 512MB or one of the generics in Bworked.

1GB in A + any of the 512s in the other A did not work, it would not post.

Also any combination of 3 dimms would not post apparently by design.

So I have swapped the DFI out for my cheap ASUS mobo and it is happely posting with 2.5GB of ram.
