What’s the point of installing a DX4/586 processor without L2 cache? I have a cyrix 5x86 without L2. After many test, i checked the L2 cache did not make almost any positive difference, in fact, oposite That’s odd.. Btw, I’ve pondered how a pod would do against a 120gp in a all out OC competition …

Bodge board, I’ve made a few of those, can’t say what this one does though. There are some processors with flexible pcbs that have stuff similar to this, but this seems to have more attachment points. Probably fixing something that was messed up, omitted, or to improve compatibility with a cpu.

Greetings! The PC I bought from ebay arrived today and is tested to function. I also bought a modded K6-2+ that has the extra cache enabled and is now a k6-III+ and the seller said that under the right circumstances, can get up to 600-633MHz. The idea is to have a system that can run as fast as I …

Ugh, may have to do this the hard way. Look up the IO chip and find pinout, continuity check to the connector, then check those relays for their singals for the vga switching, check sound card, find pins, not going to be easy.

Since multiple motherboards are talked about in this thread let it be known, 486 you need one 72 pin simm or 4 30 pin simms to complete the bus width With pentium eg socket 4, 5, 7, ss7 You need 1 dimm, two 72 pin simm, or 8 30 pin simm to populate the bus width Note: If I recall correctly, there …

Those graphs very unusual I kind of suspect that you might have damaged your North Bridge. I believe you said you tried other CPUs, and had the same result I hate to say it, but my hunch is that you have damaged silicone on that board. You can of course continue testing. I may be incorrect, but at …
