I have confirmed that using only 64 MB instead of 128 MB did not improve Quake, DOOM, 3dbench2, or PCPBench socres with either L2: WB or WT. I left my Matrox G200 installed for these tests. Setting L2 to write-through mode : Quake: no change DOOM: realtics went from 1210 (WB) to 1215 (WT) PCPBench: …

Interesting. I didn't realise at Millennium II was faster than a VirgeDX. I wonder if your VirgeDX is clocked slow? In the past, I did not notice much, if any, DOS speed change when using L2: WB vs. WT. I will run it again to be sure. For using a 66 MHz FSB on the MB-8433UUD, I found that L2-WB was …

PCBONEZ, some response to your comments: I suppose I could have used old motor oil from my diesel, but it still flows too readily. I wanted something that would stick to the surface of my glazed corelle dish. Red bearing grease is a bit gummy, true, but I can visualise it well. If something disloves …

Sorry, when I wrote "inorganic" solvent I meant that it does not dissolve organic material well, not that the solvent does not contain organic constituents. I recall my professors in graduate school always making a point to not use IPA to clean the finger prints or other oils off our gold nano …

I have at last one 386 motherboard which has a small amount of cache built into the chipset for use when no L2 cache is installed. I forgot the a mount of cache it provided, but 1 KB or less.

The Isopropyl flush will remove small amounts of oil. I thought Isopropyl was an inorganic solvent. It is an alcohol = organic. It's one of the few solvents approved for use in piping associated with primary coolant in nuclear plants exactly because it's so effective at removing contaminants and it …

Yes, please do retest with the Virge DX. I think the Virge DX and GX are supposed to be similar in performance. I do not know of any "real world programs" that will definately benefit from the faster RAM read times. I wish more of the 1995-1998 games had some timedemo. Something which moves a lot of …

If you would like to use a 3dfx card on a PCI-based socket 3 platform, the fastest commonly available CPU options are the Am5x86 running at 160 MHz, the Cyrix 5x86 running at 120 MHz, or the Pentium Overdrive at 100 MHz. The Pentium Overdrive 83 MHz is simple enough to modify to get it running at …

You results are most impressive - faster than the UMC-based board in some tests. The memory read speed is the single most result that stands out to me. Otherwise, our L1 and L2 speeds are the same. I noticed that I only scored 9.9 in PCP Bench SVGA mode. I was using a Matrox G200. Is the G200 slower …

That Longbottom guy has written tonnes of benchmarking programs, of which I have only used his DOS whetstone/dhrystone/linpack stuff. Anything of interest in his collection?

Unfortunately, most of those benchmarks are for Windows. For Windows-based benchmarks on a VLB/ISA system, the Diamond Stealth 64 Video VRAM (S3 Vision 968) was the card to have. I wish it was a little faster in DOS. Not that it is slow, but the fact that it is not the fastest in DOS as well bothers …
