755348 2009-03-10 23:45:00 HP Pavilion a1350a
RC410-M Mobo
Rev 1.01

Have just upgraded this from 512 to 2x1024MB memory.
It will only recognise 1 bank.
Both sticks will work in either bank but not in both.
Have got the correct DDR2 533 memory.
Specs say it should work.
Anyone come accross this?

755350 2009-03-11 00:04:00 This sort of picky memory problem is rife, I am afraid. It is a real PITA. Have just experienced a similar problem with two 256MB boards in an older mobo. The probable cause is bus loadings. One board OK, two presents an overload. Another two from a different manufacturer may be fine! linw (53)
755351 2009-03-11 00:04:00 Update the BIOS (h10025.www1.hp.com)

It its got XP on it, and if this applies to your system (it says RC410-M )

Is this happening at the mo??

RC410-M Motherboard BIOS update resolves issue with the system freezing when selecting Power saver mode in Control Panel Power Options

If it is, the above will fix it

755352 2009-03-11 00:12:00 Thanks Speedy.
Yes its XP sp2
Reluctant to update Bios unless absolutely neccessary as this is a business system.
This is the only issue it has.

755356 2009-03-11 05:21:00 Why?

Sorry, I wasn't reading your post carefully:p

Didn't see "Both sticks will work in either bank but not in both."

Anyways, in that case, have you tried flashing your bios to the latest version?

755357 2009-03-11 06:02:00 No as in post #5.
It's not my PC & the owner is not comfortable with a bios update.
In any case it should handle 2GB acording to the original spec.
I even tried it with 1 x 1024 & the original 512 in the other bank, still no go.
I have posted a question on the HP help line, so if I live long enough they may come up with something.
