TWINX 3200PT issue

[ytsejam02]

Hi All,

 

I have a problem where my MSI K8N Neo4 Platinum SLI motherboard diagnostics tell me the memory detection test has failed.

 

About 2-3 months ago, I bought the TWINX2048-3200PT to go with my TWINX1024-3200PT I already had installed. Initially I got the same error, until I reset my BIOS settings. Everything was running fine until recently...

 

I never turn my PC off, but I did Friday night, until Sunday morning. Sunday morning's boot gave me the same error, and it would not come back up, despite trying all kinds of combinations of the 4 sticks I have. Obviously I also tried resetting the BIOS. Eventually, it started working, though it appeared random. I finally got it running with all 4 sticks again, and I've since performed a couple of restarts with no problems.

 

It's almost as if the memory sticks needed to be a little warmed up before things started working right, though I don't blame the memory.

 

I found the following warning on MSI's webpage for my motherboard:

 

Due to the High Performance Memory design, motherboards or system configurations may or may not operate smoothly at the JEDEC (Joint Electron Device Engineering Council) standard settings (BIOS Default on the motherboard) such as DDR voltage, memory speeds and memory timing. Please confirm and adjust your memory setting in the BIOS accordingly for better system stability.

 

Is anyone aware of a compatibility issue with this memory and my motherboard? What would the recommended voltages/timings be?

 

Thanx in advance for your help!

Jay

What's the version # of each pair?

 

Note: Set your DDR voltage to 2.8 volts, the timings are correct in the SPD chip, so no manual timing changes are needed.

Not sure about the version #, is that on the memory sticks?

Actually, 1GB sticks of memory, for the most part, are not compatible at all with 512MB sticks of memory. You are mixing completely different IC chips altogether, in your case. That's because all of Corsair's XMS/TWINX series of 512MB DDR1 modules are double-sided, resulting in an IC density of 256Mbits -- while 1GB modules require at least 512Mbits of IC density to make a feasible 1GB module. And I have warned some people that mixing different IC chips and different IC densities will lead to major problems down the road, if his/her system even POSTs at all.
