Windows V CPUz Memory Report

Can anyone figure out this problem.

My PC whilst older dose the job for me but does show a funny glitch with the RAM.

Currently I have 2 GB Ram in machine (1 x 1GB 2 x 512 MB) yet Windows declares on 1.5 GB anbd CPUz shows 2 GB any idea why. THis happens no matter what order I have the sticks in. I am planning upgrade next week and will be getting new board etc but would like this machine to continue as a media server and want to sort the ram out.

CPUz screenshots

Slot 2 & 3 are identical.

Sorry for long post and I'm a bit of noob when it comes to this side of things.

Cheers

BIOS Reports 1.5 GB

Perhaps there is a setting I have wrong?

Possibly. Have you tried one stick at a time? Maybe youy have a dodgy stick. Don't see why CPU-z picks it up though!

Have you got dual-channel enabled?

If it is the memory controler might be looking for RAM in slot 4, and ignoring slot 2 (dual-channel is normally slots 1+3, 2+4)???

Only 3 slots on machine, so i dont think its anything todo with dual channel

It sounds like a double sided stick issue to me. Which sticks are single sided and which are double? and in what dimm slots are they in?

I think you need
Slot 1 - Double Sided
Slot 2 - Single Sided
Slot 3 - Single Sided

Or at least a double and two single stick when filling all slots on that chipset. Could be wrong mind.

EDIT - I'm guessing they're all double sided DIMMS after reading that Slots #2&3 are identical.

Also, I can assure you that you only have 1.5Gb available, It looks cpu-z reads DIMM bank information individually

All stciks double sided, yet if i take one of the 512 sticks out windows still reports 1.5 GB

EDIT : I'm a noob - only the 1GB is doulbe sided

Yeah, it would do, making the third slot unusable. Should have explained it a bit better in my first response:

The board basically can only address two channels of double sided RAM;

Channel 1 - Slot 1
Channel 2 - Slots 2&3

So, putting in two single sided DIMMs in 2&3 would work.
