POD = Pentium Overdrive. It is a Pentium CPU which fits into a 486 motherboard's socket 3. 83 = 83 MHz, 100 = 100 MHz.

I decided to measure and include results for the situation whereby the Am5x86-160 is run with a 26.7 MHz PCI bus instead of a 40 MHz FSB. This might be done deliberately by the user for expansion card compatibility, or by absolute insistence of the BIOS. Concerning the latter case, the PC Chips M919 …

Ok, forget about digikey. They only want to sell you 3.5 KM worth of the 32 AWG stuff for $130. The colour is agreeable though. https://www.digikey.ca/product-detail/en/cnc-tech/610232/1175-1715-ND/4924061 Anyone have an online source for this stuff in smaller rolls? I was thinking like $10 worth. …

The IHS definitely felt a lot heavier than solid aluminum. While waiting for my fan, I've ordered some MX-4. I read several reviews on the different pastes and this seems to be decent. Plus, I needed to add something small to my cart to get free shipping on amazon.ca. Will use this on the IHS and …

Recent Voodoo-based gaming results shed a new light on the Cyrix 5x86-133 stacked up against the Am5x86-160. https://www.vogons.org/viewtopic.php?t=61639 Bang for buck, go with an Am5x86-133 and run it at 160 MHz. Only in GLQuake and GLHexen2 did the Cyrix 5x86-133/4x come ahead of the Am5x86-160. …

Heh, makes me wonder if Quake could be optimised for the Cyrix 5x86 such that it out performs the Pentium. If you look at the chart for Descent 2, the POD83 is third from the bottom, yet in Quake, the POD83 is at the top. Also makes me wonder if any software was optimised for the cx5x86. This CPU …

To make out-of-order execution more efficient, these x86 instructions are translated to an internal representation. This can be seen as another type of machine code. You could say that modern x86 CPUs are 'emulating' an x86 instruction set by translating the code on-the-fly. These internal …

I'm impressed you could even get 7FPS in Unreal with a 486. The frame rate feels a lot faster when playing the game walking through that crashed space ship, if that is what it is. It would be nice to see how other systems perform. I have run things pretty well optimised and suspect not all other …

Thanks for the additional explanation. Any idea how many opcodes fit into this buffer on a cx5x86? Is the ordering alogrythm rather simple then, that is, if it is only looking at availability of resources? So are the instructions to be executed based on what hardware has just freed up, e.g. a shift …

RTV, yes... I have some of that for when I perform a differential service on my car and need to pop the cap off (though I've recently been using resealable gaskets with great results). Differential RTV is good at high temps. I also have a bunch of thin thermal tape I've been waiting to use. Perhaps …

I put the heatsink fan back on, but boy was the IHS moving all over the place. Took a few tries before I had the IHS on relatively centred. …

That is pretty intersting. What I don't really understand is how the logic works to re-order the instructions. This logic is presumably hardware-based and on the CPU itself. I would imagine it is quite complex, but what's the crux of the alogrythm? Is it like a little ASIC in the CPU dye? Also, to …

I have removed the heat spreader on my Opteron 185 and have a few questions. 1) Has anyone performed a delidding and left the heat spreader off, thereby placing the heatsink/fan in direct contact with the surface below? What was the outcome? Wouldn't this be better for cooling, that is, to remove …

How is it possible that a motherboard can support up to only 4 GB The answer is simple: unbuffered DDR stopped at 1gb. Wouldn't the BIOS and the ULi M1695 northbridge need to support 8 GB of RAM? Does the northbridge on the 939dual-SATA2 or 939dual-VSTA support 8 GB? there are 4GB "High density" …

Enclosed above are the gaming results for select high-end socket 3 CPUs, tested in 3dfx glide mode with a Voodoo2 in Windows95. The Voodoo2 was selected over the Voodoo1 because it was about 12% faster on this platform. For all but one minor exception, the Pentium Overdrive clocked at 100 MHz came …
