Hi all, i have bought 512mb ram, (PC100) but my machine is reading just 320???

This is also with my old stick of 64mb attached as well. I have a tiny pc, motherboard PAG-2130.

Any help will be appreciated......

I think your board only supports 256MB Ram chips. Is the 512MB 1x512MB or 2x256MB?

Hi Zaxifone, they are both 256 chips. I checked the m/board site to make sure i could use 512, and it says it can. Bear in mind that without the old 64meg chip that was in there, it was only reading about 290mb????

You could try the chips in one at a time and see what they register. Sounds like one of them could be faulty. Also, try moving them around in the memory banks, one may be needing cleaned...

i will try cleaning them etc, but even when i put them in one at a time they are reading about half....hmmmm, do you think they could be branded incorrectly, that is something i hadn't thought of......

Does the 64MB one have chips up both sides, but the others only have chips up one side by any chance?

all up both sides.....

And the 64mb one reports correctly? Hmmm....strange one...I suppose it is possible that they could be branded incorrectly. Can you try them in another computer?

Alamost ceratinly it is because older motherboards only recognise ceratin data organisations in the chips - particularly the difference may be that they only recognise 32 bit data chips. For instance a 512 Mbit chip may be 8x64 bits - or 16x32 bits. On older m/boards the first would work, the second would show as half the true. capacity.

So your 512Mbyte chip would show as 256Mb - plus your original 64Mb = 320Mb.

Thanks for your suggestions, i'll try the chips in another PC, if they work, i guess i'll live with it!

Thanks again
