Hi people,

Got a HP xw9300 machine with 2 X dual core processors that we use for some video editing and graphics work. Up until this week we had been getting by with 2GB of RAM, which is arranged in the slots in 4 x 512MB sticks. The new RAM I have purchased is the correct speed and spec, as recommended by HP, but in 2 x 1GB sticks. No matter what arrangement i try with different pairs in different number slots, I cant get the machine to recognise any more than 2GB RAM. Any ideas why??

The machine has ATI radeon graphics cards and matrox video cards if this helps.

How much RAM does the two graphics cards have? If you are using a 32bit operating system you are limited to 4GB and that includes the RAM on G/cards.

stballs.

forgot about that - think they have about 1.5 GB between them which might explain it.

Really? I'm running 32 bit Vista on my desktop, with a 2GB NVidia graphics card and 4GB RAM. My PC reports 4GB RAM.

32bit systems can only address a max of 4GB of memory, whether thats system ram or graphics cards or anything else. There are ways around this but long and complicated and not worth worrying about. Its hard to say why your system still reports 4GB especially as even with only a 64MB graphics card in it should report only about 3.5GB due to other issue.

Actually, I was wrong, my system has 8GB RAM:

Manufacturer: MESH Computers

Processor Intel(R) Core(TM)2 Quad CPU Q45O @ 2.66GHz 2.67 GHz

One of the updates for 32 bit Vista changed it so that it reports the total RAM in the system but you still have the usual 32 bit addressing limitations.

Yeah, it reports it correctly now, but unless you're running 64-bit you can't adress more than 4GB. With 1.5GB of video RAM you could be well below 3GB addressable.

sucks to find out afterwards

maybe upgrade to 64 bit vista ?

windows index is 5.4, cpu is 5.4 and everything else is 5.9, hindsight is a wonderful thing smile

No reason not to - 64-bit Vista is pretty compatible now, there's only a couple of programs that won't work with it that I can think of.

You probably dont have the patch so are getting an incorrect memory report under 32 bit windows.

Grab a linux 64bit dvd, boot from it and run memtest - that should tell you what you really have and if it works or not.

Posting in this thread as I have a similar problem.

XP Home
ABIT AA8XE Motherboard
2x512 DDR2 Corsair
2x1Gb DDR2 Axus, Aceus... something A-ish...

PC won't recognise the old 2x512 RAM I have put into the slave but does recognise the new2x1Gb I've placed into the slots where the 512 was...

GC is a measly 512 so shouldn't interfere.

You may well have the exact HP spec memory, but unless its HP Memory, then there is a very very good chance that it will not be reconised.
If your new sticks are not seen in Bios, and you have paired correctly that is a very good indication of your identical spec ram sticks not been compatable. Ho-hum banghead

Ex HP Engineer, used to get called out regularly for this, happens on the vast majority of HP Servers.
Some people are lucky and their cheaper non HP branded ram works.

Make sure your running the latest Bios for your machine.
Try borrowing two more HP Sticks to proove.
