TWINX1024-3200XL+MSI Neo2+3200+ (Winchester) = OC problem, please read!

[CuPrid]

Hello everybody!

 

This is my first post, and I hope you are able to solve my problem(s)!

 

First off, my rig:

MSI K8N Neo2-Platinum

AMD64 3200+ 90nm s939

2x512MB Corsair 3200XL (2-2-2-5)

Zalman 7000B-Cu

Tagan 480W

And all my hard drives are IDE

 

Second, my problem:

 

I can't get my system stable at 1:1 no matter what I do, but I can get it stable at 5:6 with these settings;

HTT: x4

Multiplier: 10x

FSB: 250MHz

Vcore: 1,525V + 5%

Vdimm: AUTO

Max mem clock: 166 (5:6)

Timings: 2-2-2-5 1T

Aggresive timings: disable

AGP: 67MHz

 

And this is stable!

 

When I try to run the system at 1:1, I uses the following settings;

Vdimm: from 2,60V to 2,85V

Max mem clock: 200 (1:1)

And tried the following timings: 2,5-3-3-6/7/8/9/10 1T

 

I ran Memtest86 with the memories at 2,85V 250MHz 2,5-3-3-10 1T, and with this I didn't get any errors! Memtest86 says that my memories are okey at 2,85V 250MHz 2,5-3-3-10 1T and I know that my CPU are stable at 1,525V + 5% 10x250MHz. Why isn't it stable in 1:1 then?

 

I've also tried to move the dimms from dimm 1&2 to dimm 3&4, this resulted in more "stable" in Prime95, but the system rebooted sometimes(?).

 

I've also tried with the following settings;

HTT:x4

Multiplier: 8x

FSB: 220 - 250MHz

Vcore: default

Vdimm: 2,85V

Max mem clock: 200 (1:1)

And tried the following timings: 2,5-3-3-6/7/8/9/10 1T

 

Same **** here, it's unstable. I know many people who has got the same system as me and they can run it at 1:1 stable!

 

Come on now, please help me! What should I do to get the system stable?
