I have an old soyo 82430VX/P54C PCI motherboard that I'm trying to restore and upgrade to use for some tests, then donate to a museum, but I'm looking at 128MB RAM on ebay, and see that a lot of the memory available has a 60ns access time, but this board says in the manual that it needs 70ns. would the ram still work, but slow the speed down automatically (or manually) or would it just not post?
I don't want to get some RAM from the states and ship it half way around the world just to send it back, and it's not like I can just go back to 1995 and to the Tandy store I bought this thing from any more.
Anyway, would it work? is anyone willing to donate or sell me some working RAM?

One last question, can someone give me a value on this machine?
Pentium 133 ( came with a 75mhz)
32MB RAM (to be upgraded)
1MB ATI RAGE PCI graphics
2 floppy drives
1GB WD hdd
CD ROM drive
windows 95 ver B
 
Faster RAM should work fine in a slower system.

As for the "value" of such an old system, unless you can find someone who desperately needs or wants to run an application or game that does not work on remotely modern systems, it is worth scrap metal value if you separate the metals from everything else first. Recyclers won't offer you any money for it since they need to cover the labor cost of dismantling it.

BTW, you may even have trouble finding a charity that will accept a donation of this PC since it will have a hard time running anything newer than Win98SE.
 
I got 128mb in 2 64mb simms from ebay, but when I installed them i nthe machine, the POST memory test only shows 32mb installed, and running one stick causes the machine to not post so I assume these are paired sticks. If I install my old RAM too the PC sees 64mb installed, so it can't be a mobo limitation to that amount. Why would this be happening? The manual says the board can take up to 128mb, 70ns with no other info given. I think I read somewhere about having to upgrade cache on my motherboards a few years ago, could this be it?
