That reminds me of 1999, where I threw a party to help my friends modify their Celeron 300A CPUs so they could run dual-socket. My dual 300A running at 450MHz would run Starcraft under WINE faster than Windows could run it because at the time Windows couldn't do multi-core. Under Linux one processor would run the graphics (in X) and the other would run the game mechanics, and it would blaze.

Was that the period of time when you got more bang for your buck building a PC with dual-socket Celerons than one high-end Pentium?

EDIT: An excellent retrospective on it here: https://www.youtube.com/watch?v=UE-k4hYHIDE

    Yes, the dual Celeron 300As, if you could take advantage of multiple cores, were faster than the higher end CPUs, particularly if you overclocked to 450MHz. My box was stable at 450MHz for around a year, then I had to gradually down-clock it, eventually back to 300. Never really did much to track down why that was, just rolled with it and figured I should be grateful for the overclocking I had.

      I also ran a dual Celeron system overclocked to 450mhz - it was great value in 1999. Abit even launched a motherboard that let you run dual Celerons without modifying the processors, the legendary BP6:

      This was first board to let you use unmodified Celerons, the "hack" to let dual CPUs work with those chips was performed at the motherboard level, no CPU pin modifications needed.

        The real problem with this setup was that a vanilla Pentium 3 would run circles around the dual Celerons. I had my Celerons clocked to something ridiculous at one point like 600MHz and still could not beat the Pentium.

      About a year later, I got the P3-550 that overclocked to 733. Not quite as good of an overclock in terms of percentages, but I ran that machine for 5 years with no issues.

      Did you pet you cpus at the end and say something like, “you had a good run boys but we best be putting you out to pasture.”

      iirc those overclocks needed thermal paste to be reapplied, plus dust in case probably crushed airflow

I hate you.

Well, just envy hate and just momentarily. Back then, such hacks were harder to find/discover. I would have loved to do that hack, I yearned for true multicpu.

    That stuff was all over Slashdot at the time, where I heard about it; even got one and ran it for awhile, eventually relegating it to a Linux server.

      For some reason I feel like running home stuff fell out of favour. Or perhaps, I stopped doing it. I would prefer to do it again however I don’t ever have an idea what to do with it since these days I just stream everything from the internet. And I have plenty of cloud compute for whatever I want to do.

        People call it "homelab" or "data hoarding" these days, but yes, the easy access to hours and hours of movies and music was "solved" for the average person by the content streaming sites, so there's not as much a drive as there used to be for it.

        Heheheh, drive.
