The last time I made a post regarding PSUs was a while back, but I now have a refreshed fear of the ones I've been using due to my new motherboard having set me back ~US$65 and the fact that I can't get another one for a very long time if this one goes. They are Dell power supplies, ca. 2003. I use …

An update on the build: Not much has changed except that fact that I took it apart, cleaned it, and replaced the old noisy front panel fan with a new, slightly quieter one. I also "improved," cable management- I had to stress the IDE cables, but if I don't, with the way the case is designed (no …

@retardware I cannot find a K6-III 500/AHX on ebay. I found a K6-III+ 400/ATZ (1.6v reaches 600 MHz at 2.1V) model. But it is very expensive. 135.00 € asks the seller. What the Hell? Who is going to spend that much money on a friggin K6-III (no offense to the K6-III, but seriously)? You could build …

If you're really paranoid, one way to ensure you aren't overheating is to buy a big 'ol Socket 370 heatsink, and stick it on Socket 7. It's essentially a perfect match, and the TDP's of the 1GHz+ Pentium III's are much higher than SS7 CPUs at stock voltage, but even with the 2.6v I doubt it will …

Later Pmmx chips were multiplier locked. Your PCI bus overclocking at 41mgz might be causing more trouble along with not upping the voltage. Past experience is that the P200mmx does not over clock well, even after upping the voltage. Best performance for me was 100mhz x 2x for 200mhz on a pc100 …

So the BIOS does not report accurate speeds above 233mhz, sort of common. That particular CPU may not be able to handle any more, sort of the lottery with Intel cpu and OC speeds. Also SIS TX series chips are not well known for being OC friendly unlike the VIA MVP3. There is also the cache and …

I got bored while waiting for parts to show up for my PII 400 machine, so I started pushing the P200 in my SS7 build to see if it could do anything. Spoiler: it can't. This is the worst overclocker I've ever seen. This CPU can do only four things: underclock, stay the same, overclock slightly, or …

The Gateway Tabor (and other Gateway motherboards round that era) are actually made by Intel which is why they are such high quality :) I've always thought that my Tabor III looked freakishly similar to my old SE440BX-2, I guess that's why. An odd thing to note is that there are some 440BX …

Eh, my Slot 1 build isn't working. Throws a code 00C1 (bad RAM), but all of the RAM sticks work in my Socket 370 build, which means the caps on the board are probably shot. ASUS P2B-F is the board and it has a Celeron 400/66 Slot 1 installed. Going to build another Socket 7 system or upgrade my …

This is likely going to be a semi-long list, but here's a few computers I've wanted to build/buy for a while: A full-tower ATX dual Pentium Pro 200MHz server with 256MB of SDRAM and a few 4 or 8GB SCSI drives in RAID, with a tape backup drive, running Windows NT 4.0 server. This would be a main …

I agree. The PIII / Athlon era was a circus of broken CPU dies and gouged motherboards near the CPU fan clip. I worked for a computer store during the tail of that period, leading into the P4. Mmm, and I bet once those P4's and P3's with heat spreaders started appearing, the screwed up dies went …

I did something I consider stupid, and took the heatsink off of my Coppermine and put it on the PII 400. A) I wish my PII 400 did not have an exposed die. I f*cking hate exposed dies. To whatever horrid, demented engineers working for Intel when this CPU was produced, who hurt you? B) I hate all of …

OK, you make a compelling argument -- that little guy OC's like a champ. (I would still go with a PII just 'cause, but I never really have cared much about benchmarks, so take that with a grain of salt.) :-) I don't personally care very much for benchmarks either, except when it pertains to a …

I would go with the PII-400. My first ATX build (and it was in 1999, I think) was an Asus P2B with a PII-350 in an Enlight case running Win 95. Perfection. I had never had a computer that stable and consistent before, and I ran it hard straight into the ground over the next few years. (Still have …

486's are cool and all but this is a much nicer dos SVGA build :) It took a while to get it to do anything at all, including getting the ESS sound card to synthesize MIDI, but once I got it all working, all the DOS games I play that use MIDI sound great. This is important because the MIDI on my SB …

Things have changed slightly since I made this post. First, I got very lucky to be given US$100 as a present, and once I got home I immediately began searching online for Slot 1 motherboards. I came upon an EPoX EP-61BXA-M, a 440BX based motherboard that is old enough to see PIII 450MHz CPUs as PII …

What about GLQuake, does that run? :happy: It changes the screen resolution down to 640x480, while remaining on a zoomed in upper left hand corner of the desktop, and gets into a loop of making 15-bit inverse pallets, over and over, and once that loop ends, it will just sit with the top upper left- …

Well, ever since I got a new AGP card, an 8MB ATi Rage 128, it's changed... nothing. That's right. Nothing. The same exact problems are still present. It refuses to do anything above 640x480x16. This is a problem, because if this is an AGP issue, the only PCI card I have is a very dodgy Trident TGUI …
