Memory sticks pass dimm slots pass but I still get a fail using memtest 86+

[fastrider]

Hi,

I have just purchased a HP xw4300 workstation, its in great condition running XP pro 32bit although it is the x64 version.

My problem is It came with 2 gig of ram fitted, 4 x 512MB ( 2 x 1 rank, 4 banks and 2 x 2 rank, 4 banks)

I am getting an intermittent BSOD memory parity error but only with the 4 sticks fitted!

The computer runs fine if I remove one stick and it doesn't matter which slot I remove it from.

ECC is enabled and I have tested the 4 sticks and the 4 slots, individually they all pass memtest 86+

but as soon as I install them all I get a fail on test 5 and the intermittent BSOD.

bios is the latest version 2008 and as I said earlier it runs with no problems with 3 sticks installed.

I'm thinking it maybe easier to get 2 x 1 gig sticks.

anyone?

thanks for all your help.

You may need to bump the voltage slightly on the memory (MCH) controller when using all sticks. Also, not sure what voltage your DIMMS are listed as, but make sure it's set properly in the bios.

Its a pre built so theres nothing in the bios to change, do you think SetFSB would work ?

thanks keefy

I don't think setfsb will work. I'm not familiar with it, but it looks like a clock control for the FSB, not a voltage regulator.

Without access to the bios, specifically the MCH, I'm not sure what else to try. Hopefully someone else will chime in.

Well if you just purchased it, I would return it. This might be a faulty system that got passed their QC dept.

 

[fastrider]

Yes thats what I thought, I might email HP and ask them, specs that I have read state that it will take up to 8 gig of ram although xp 32 bit will only see 4 gig or along that line.

the computers been running for 24hrs on three sticks with no problems.

thanks keefy

I should have said in first post that I purchased it used, tower only.
