I was sure that 256 was the limit, but I decided to try for myself. Starting with a 256 PC133 in one slot that I've been using for some time, trying any of the other 256 meg sticks of SDRAM I have in slot 2 would just cause it to beep without posting. But there were a couple of different 128s that …

The board very likely has jumpers on it which dictate the set voltage. On socket 7, it's anywhere from 2.5v to 3.5v. Look up details for your motherboard to see info on how the jumpers should be set for the voltage, or maybe you have a diagram silkscreened somewhere on the board. I’m going to be …

What’s the easiest way to verify cpu voltage? Can I set the voltage wothout a cpu installed, power it up and check it or should I install a higher voltage cpu and test it then install the lower voltage one? Also how do I check voltage with a volt meter on socket 7? Do I have to test at the back of …

Looks like an AMI bios and that gives this: "94 Memory size set" Any idea what it means and why specific pci cards would have anything to do with memory I may have found an explanation to that code. With UEFI, status codes are still written to port 0x80, but in a different way (see page 13): …

I was thinking of ordering some 128mb simms for this also maybe some 64mb ones. Anything I should look for? Anything that would stand a better chance of working? Are we pretty much consigned to “using simms and dimms together” as not being a tool for cramming more ram in there?

[...] Thank you. The reason I mentioned BIOS is because of I know that at least some 440BX boards, for example, required BIOS updates to recognize 256MB DIMMs at full capacity (I am referring only to DIMMs that should be compatible, according to https://web.archive.org/web/20180103032407/ht … ram_ …

So does this bios patch apply to my board? How can I find out? I’ve been able to get 256mb in it before but no more than that. Question is, is that because I didn’t try the correct parts? Depends on the parts... Indeed. I don’t have any of those ram sticks any more but at least I know I have one …

Have you been able to locate the datasheet for the motherboard's onboard PLL (PII52c62-01xc)? Most boards use generic PLL clock generator chips which normally have a 83 MHz setting. On some 430TX boards, you will need to disable the onboard L2 cache for the system to work at 83 MHz. On my board, I …

A faster P3 compatible CPU would be cool so you could have a faster system with an isa bus (barring some exotic p4 boards), but the tualatin is already strangled by the low memory bandwidth of the P3 bus so there's little point. Another approach would be a motherboard that somehow offers retro …

The middle two are registered, they're not going to work on a non-server board. Desktop chipsets only eat unbuffered DIMMs. ECC or not is irrelevant. Bottom one is iffy, for starters it's 128MB, and looking at the datasheets of those HYB39S64800CT-8 chips shows they can be configured either as 8Mx8 …

Hello :-) So I have a p55xb2 socket 7 motherboard with two sd ram slots and four simm ram slots. I’ve previously been able to get 256mb into it and that’s about it.

Well there's tons of new stuff for the Amiga aficionados. Tho that's mostly because the "real" old upgrade hardware is so expensive almost no one can afford it. On the other hand there's tons of old PC gear floating around (unless you wanna tinker with really "weird" stuff). Also if you want more …
