Nice board! It'd be good for a PCI Voodoo build too. Re CPU multiplier - is there no jumpers on the board itself? My 440BX Supermicro board needs physical jumpers changing as per each CPU supported.

So I got hold of another Pentium II 450 - works fine first time after changing the jumpers! One question though - it looks to have a third party heatsink/fan with an additional 2 pin connector - does anyone know what it's for?

However, I've swapped it over today and it's causing all sorts of errors - memory problems, graphics distortions, system hangs, CMOS errors, etc. Try to clean the contacts. Few Pentium II/III in my collection required cleaning to just work. Did this today, and also attached a fan to the heatsink, …

I don't have a fan to install though. You can see in the pics above that the heatsink isn't designed for a fan to be attached and there seem to be an awful lot of slot 1 Pentium 2s and 3s with those style heatsinks without fans, I can't imagine they all need fans somehow attaching to work. A quick …

Hi You havent by mistake got one of the first P3 450MHz chips? if so they are a bit different and the bios may be upset. I had this issue when going from a P2 400 to P3 550. Board had issues like this until i found a BIOS update. (HP oem version of an ASUS board). After the BIOS it took an 800MHz …

It's got a 120mm fan above it pulling air out. My 350MHz has a fan on top of the heatsink but it's not very big/strong. Can't imagine it makes that much difference. Install the fan to push air. And that small fan on the PII 350 does make * a lot* of difference, trust me. Play some game with the fan …

Does your case have enough airflow to properly cool the passive heatsink? Have you tried putting a fan pointing right on the heat sink to see if anything changes It's got a 120mm fan above it pulling air out.

Try to format the HDD, it shouldn't have any sense, but in this way you could start to discard options. Won't get that far, it crashes in the BIOS trying to check the CPU temperature (39 degrees). Do it only crashes when you check the temperature?, What more options in the bios causes crashes?. No, …

Also, can anyone say anything good about the Astec PSU brand in general? I'm keeping an eye on a SA202-3545-2288A. The 200W power output seems ideal for a Pentium (1), but I can't find any reliable info about it. They're pretty decent. Lots of OEMs used them back in the 90s (I've had a few Gateways …

Spent all day trying to decide whether to buy new graphics cards for my Pentium II machine, reading old reviews, watching YouTube videos. Currently has a Voodoo 3 3000, but I've found a cheap 3D Prophet 4000XT on eBay. 3D Prophet was the first card I ever bought back when I was 12, but I think my …

Wow, thanks for all the replies! Lots to think about... You don't play games with them, you don't fiddle with their innards - what do you (intend to) do with them? The answer to that question will probably go a long way towards telling you which to keep. Without that, others will just say what *they …
