OCZ ram and a P55A-UD3 motherboard only see's 4gb not 8gb

If you have it set to 32 then try changing that to auto first.

[scoutermike]

for that setting the choices are auto, x32 and x36 only.

[Dark Mantis]

Yes that's why I said change it to auto

[scoutermike]

it is on auto.

I am not sure what is going on in this BIOS but we don't seem to be winning here so the next step is to check the CPU socket.

This is a very delicate operation so extreme care is needed.

Remove the CPU/heatsink/fan and have a close look at the lands(pads) underneath the processor. Each one should have a mark in the centre (maybe more than one if it has been refitted before). If there are any without marks or the marks are far off centre then it could be a problem with bent pins in the socket.

Hi, I checked the socket and there was one bent bin in the upper right hand area of the cpu socket, I unbent it and put the computer back together and it is still the same.

[Dark Mantis]

Not doubting you but are you sure:
A) That there was only one bent pin? They are quite difficult to spot.
B) That when you "unbent" it the pin was as good as new?

If you are in any doubt please just take a couple of closeup (Macro) photos for us to check.

[scoutermike]

I just took it apart again and the pin is as good as new but I noticed on the bottom of the chip that not all the pads on the processor have a mark on them from the pins is this normal? I don't know how I bent one pin anyway, I only placed the processor in the socket and locked it down.

Have a look at the proceesor where the pads have no mark and then check the corresponding pin in the socket and see that it is actually in line and not bent. Also don't over tighten the heatsink down too hard on the cpu. see if that helps.

Pics of the CPU socket  please, using macro, no flash, and good lighting.

That is precisely why I asked yop to check the pads on the CPU first, but you jumped ahaed and went straight to the socket
As I said before if you take some photos we can check the socket out for you.

Hi, thank you guys for all your help, this forum is great. I had a feeling the board was doa so I took it back and got another today and everything works
it show's 8gb of ram. Problem solved.

[Dark Mantis]

Thanks for the update. At least you have a board that works now.

[Lsdmeasap]

Great to hear you got this sorted with a new board, that's always an easy fix
