My P3C-E has only worked with PC600 RAM. Probably not the real cause, but might be worth a try.

Okay, I am dumb. The ports were switched... I guess what threw me off, was that even the USB keyboard did not work, or that they were not labeled. Aaanyways, on a related note, is it possible to flash an original Intel BIOS? I assume I will have to do some soldering though, since I noticed that the …

Hi, I recently bought a Intel OR840 motherboard from an IBM Intellistation M type 6889 workstation, however, I am having some issues with the built-in Security system (probably). Right after POST splash screen, I get a message, that the keyboard is locked, followed by Intel boot agent and followed …

Thanks for the photos. As it turned out, I just bought some more SP750 components from the same seller, probably from the same machines. Before I finalize the order, is there anything else I'd need to get at least one working?

The originally came out of a Compaq/HP SP750 workstation. Dual Slot 2 + RIMM RAM + AGP + Intel chipset. Pretty cool. DSC_7287.JPG It's essentially identical to what is shown on this listing . I have the memory boards too, but not at hand at the moment. Also, the board doesn't have any ISA slots.

I have recently bought three bare motherboards with the memory boards, but unfortunately, but unfortunately, they have proprietary power supply connectors. Custom 10 pin and a 20pin, that fits a standard ATX PSU. I kinda hope, that I might be able to splice something from an standard ATX PSU, but I …

There is very little in terms of a performance increase with dual socket boards. Although, you probably go and fiddle with the CPU affinity, but the improvements will still be marginal at best. The real reason why people (or at least myself) build with dual socket boards, is simply 2 > 1. And that …

I am at 184 motherboards at the moment. Most of them work, some require some work. WOW, That is a lot of boards ! I only list those that will successfully fully boot and pass a few tests, have a stack that does not pass so never include them in my "working board list". You have like 2X what I have …

I am at 184 motherboards at the moment. Most of them work, some require some work. Only three cases though. Here is the list: https://docs.google.com/spreadsheets/d/1LAq-0 … dit?usp=sharing

Hi, I have an opportunity to purchase a pair of 900MHz/2MB Intel Pentium 3 Xeon CPUs, which are in theory, the best CPUs to put into my Supermicro S2DG2. The issue is, that they have the 5/12V Core voltage, which to my knowledge, the board doesn't support. But I can't find any evidence to prove it. …

My personal favorite is probably the T23, but from what I heard, it does have sound card compatibility issues in DOS. The earlier T20 to T22 are fine though. I am also not sure about compatibility with the super early DOS games. For later games, it's either A31p or something from the T4* series with …

From what I understand, your best chance is to cut the necessary length out of a threaded rod and then use a few nuts to secure the card in. There is no set standard for anything like this, so that is your best chance tbh.

The connector on the fans looks to be pretty much the same as a CPU 4pin (P4) on more modern power supplies, just with a different pinout. What you could do, is to crimp molex connector on the end of a P4 extension cable, like this one. While what PC Hoarder Patrol said is most likely the easiest …

Obligatory "this is not that recent, but it happened, I swear!" So, a couple of years back, I found a MSI K7D Master -L motherboard for sale for a decent price, including a pair of decent Arctic coolers and most importantly, a pair of Athlon MP 2800+, with Barton core, running at 1.6V of VCore (this …
