MSI K9A2 Platinum running 1066Mhz 2x2GB need help

[Razrback16]

I've had similar issues with mine. I don't have any suggestions to fix, only wanted to mention that mine is not stable using the 1066 setting at any speed, even underclocked. I've read of others having similar issues. You may need to resort back to 800MHz for stability.

Did you try AUTO Ram settings with the recommended Volts with only 2gigs first(1stick. If it runs and doesnt error ..Are both sticks in the correct slots for DOUBLESIDED or SINGLE SIDED DIMMS?


This is a long shot but usually helps alot..Raise the CPU to SB/NB volts or which ever is the NORTHBRIDGE on the Mobo not the CPU..

You may need to set itNBmobov @ 1.28-1.31v for 2x2gig sticks to work with that mobo..and use ganged mode.

SB600's dont have the correct Volts enabled to push 2gigs in each slot..So slightly Higher NBmobo volts in bios to handle 4gigs in two slots should do the trick

Just boot with one stick and set the Volts and NB on MOBO then stut down install Both sticks ,,Have fun..

Once you get them to run stable then you can worry about optimal timings...Also disable any AUTOtweaks for ram and make shure to use MAXRAM speed or high freqency setting when set to 1066. I forget what MSI has in thier bios..They can work ,,the Bios just isnt optimized for 1066 with 2x2gig to just PNP.

Note:
Read your Auto timing with One stick @ 1066..It should read something like 5-7-7-24-2T..If its doing what i think its doing. That should be default fo most bios to boot 1066 for Phenom....Have tested this with 8500 4x1gig which will require the same amount of volts for CPU to sb/nb chipset,, Stis is for stability even with stock CPUcloks...PatriotViper4x1//CrucialBalls4x1//Also2x2 and 4x1DominatorD9's//6400cosairsDHXC54x1//kingstonHypers 4x1.


I was able to get all to boot and run with no errors.. But if i kept the CPU- SB/NB to stock volts it would not run all four sticks 4gigs stable only two..

Ive tried the new 2x2Corsair Dominator kit and it worked the same way..Had to use one stick to set the volts then was able to add the other..

Hope that helps..
