Single and double sided PC133 RAM

[Pizza Man]

Hi all,
First post here. I tried to search for the information I am looking for, but after reading through a few different threads I couldnt find any thing close to my problem.
I am running a POS (Piont of Sale) system in my shop here and have some older (766mhz) machines that run win2k and work perfectly fine tor the job they are doing.
I picked up 2x2565 ram chips to bump up the speed of one of my machines. It appears that I needed to get double sided ram. Single sided anything doesnt wor, I tried 32, 64, and 128 with the same results. Nothing single sided worked for me.
Is there a way to work around this? I am using the Hitachi Flora 310 DP1 (http://www.hitachi.co.jp/Prod/comp/OSD/pc/flora/prod/oldmodel/desktop/spec310dp1_010302.html
(sorry I couldnt make the link and that it is in Japanese).

Anyone know a way to get this ram to work?

Thanks in advance.

Welcome to the forums Pizza Man. :)

If the system only supports double sided ram there is nothing you can do. The system just can't communicate with high density chips. You will need to pick up some double sided ram. Hopefully you can return the ram, or use it elsewhere.

That thing uses the SiS 630 chipset. You can't run a 66 FSB CPU with PC133 SDRAM. The difference is just too big. You will not only need single-sided sticks of 256MB, but they will also need to be PC100.
