Hi all

 

Whilst working on an ageing Xp unit (HP Pavillion a.115.uk), I noticed that it only had 256mb plus 128mb of DDR ram so I removed the 128mb, hunted around and found some old 256mb sticks and bumped up the total to 512mb (the max is 1gb).

 

I noticed the pc doing odd things so I ran memtest86+, using one stick at a time (same slot each time).

 

The original 256mb Infineon failed, as did the three other Infineon 256 sticks I had. The fails were on the random number sequence test (#7).

 

Only the 128mb sticks passed.

 

Is this little more than a coincidence? Or is there possibly something else going on?

 

I hope to order two 512mb sticks but just wanted to double check first

 

Tnx

Ahhhh... seconds after posting I discovered that there is a bug in the version of Memtest that I am using that occurs above 129mb.

 

I was using the one bundled in with the Ubuntu distro.

I guess I should download the ISO from memtest and test again (I think the floppy drive is dead).
