XMS 3200 C2PT and Asus A7N8X-E Delux PRoblems

Guys,

Newbie, with a bit of a problem.

 

I have a Asus A7N8X-E Delux Mobo running a 3200 XP processor and Win XP PRO.

I originally had 1 X 512 MB module of XMS 3200 C2PT (3202V1.2) which was rock solid and performed fantastically.

 

So of course I wanted more and bought a Twin-X pack which was 1024 C2PT (3202V3.1) and sold the 512mb stick.

 

Now, running in dual channel mode ( with the modules occupying slots 2&3 on the MObo)the system has become unreliable and gaming is just not an option as the system crashes after only a few minutes,....am I doomed never to complete Doom 3 ? :[pouts:

 

What is the difference between these two chip versions (3202V1.2 & 3202V3.1)?

Why the dramatic change in performance?

Should other sticks of C2 3202V1.2 be ok with my set up? or was I just lucky?

 

I have spotted two sticks of 512Mb XMS 3200 C2 on ebay and I am thinking of buying these and ditching my Twin-X modules.

 

Anyone help ?

 

Please !

Please test your modules one at a time and I would try these settings and test with http://www.memtest.org and lets make sure one is not failing.

CPU Freq: 200 MHz

System Performance: User Define

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Spread Spectrum: Disabled

Resulting Frequency: 200 MHz

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

Then please test with http://www.memtest.org one at a time.

Rev 1.2 was based on Winbond IC's and Revision can be made with Mosel or Promos IC's

You went from single channel to dual channel for one thing; second there are a few threads about this MB at http://www.asusforums.org under the AMD section that will help you. And when using more than one module they would or should all be the exact same part# and revision for best performance.
