right im runnign my com on the expected faulty stick (1gb) and before when i tried it with just two 1gb it came to a blue screen, i so far have had no blue screen on this attempt, so to sum up this stick is not faulty so i expect i am having an issue with using the two 1gb sticks together?

So running just one or the other 1GB is fine.

It's only when they are in a pair?

[mrdaveyk]

pretty much i can run 1gb and two 512 fine but when i add the other 1gb is when the problems occur such as the big blueee and my computer showing 2.5gb instead of 3gb

Do you know the make and model of your motherboard?

[mrdaveyk]

aye reading off msinfo 32 its winfast 6100M2MA

[Hybr!d]

For reference your motherboard is made by Foxconn.

That RAM should be fine.

It's possible I guess that both are fine separately but one has a fault when running dual channel.

As it is hard to narrow down which one has the fault I'd return both and get them swapped.

appreciate it mate!

You're welcome.

dave, ive had about 3 topics going and you seem to be determind to help me at all costs i have an update, i have now decided to put 1gb in slot 1 slot 2 empty slot 3 empty and slot 4 the other 1gb... and theres no problem......

im going to add one 512 in slot 3 and see what happens .....

[Hybr!d]

Slots should be in pairs.

1 and 2 - Both 1GB
3 and 4 - Both 512MB

Miss matching slots like:

1 and 4 - 1GB
2 and 3 - 512MB

Will cause performance issues, even if it works it isn't working the way it was intended.
