The Cyrix it shall be then! I realy like the fact is has a lower 150MHz clock for older games, but at the same time a higher FSB than a Pentium 166MMX or 200MMX, otoh no MMX and poor FPU Did somebody say CYRIX? How does a Cyrix MediaGX sound for this project? The GXm's had MMX and my preliminary …

These sell new for $15.99 + $18.99 shipping. http://www.ebay.ca/itm/221058801591 The case has a very clean appeal to me. The only thing I don't really care for is the offset grill on the side panel. Apparently, the ones that eBayer is selling are all like that. I don't know why his photo shows …

That Matrox asking price is just silly. I don't believe any Matrox G200 PCI cards had SGRAM, so you would actually be looking for an SDRAM upgrade module. The AGP G200's came in SGRAM and SDRAM.

Usually it is OK to simply disable USB and network cards in Windows Device Manager. For slow CPU's, like 486's, I noticed that when USB (and network?) cards were installed, they slowed down the benchmark scores, but the scores bumped back up when they were disabled in Windows. I believe the main …

Thank you for interest in this project; please send me a PM when you have time and if you are still interested in testing. It takes about 3 hours per CPU and requires about 100 numbers to tally per CPU. You will need a Matrox G200 PCI w/16 MB RAM.

Hello Neon_WA and welcome to the forum! Your avatar is certainly recognisable from other PC-related forums. I was keeping a list at one point, but it kept growing and changing, so I stopped updating it. I'll re-update a list near completion. A very outdated list can be found here, http://www.vogons. …

I checked vspeed with the Klamath 133 on the VIA board, here is what it gets. Vspeed results without FastVid - banked=26.54 MB/s & lfb=29.49 MB/s Vspeed results after FastVid - banked=72.62 MB/s & lfb=94.74 MB/s

5 FPS in Quake 1 is a big jump! I decided to try Fastvid on my VIA slot 1 board with the Celeron 400. I had originally thought it was only for Intel 450/440 boards, but the VIA FastVid results jumped 3-fold. Before FastVid: DRAM to banked VGA: 36.86 million bytes/sec DRAM to linear framebuffer: 38. …

133 MHz? Those vspeed test results that I posted were with a Celeron 400A at 400 MHz, which is where I am in the testing right now. I didn't bother putting the PII-133 back in. For comparison, a Geforce 6200 on a 440BX board w/PIII-850 gets, 37.6 million bytes/sec 49.77 million bytes/sec for those …

I have Fastvid bundled with 3dbench. I ran it, but I don't know how to determine if the results are due to a bottleneck.

The third item down in that photo is what you want, that is, refering to the link Jolaes76 posted. It can be -10, -12, or -15. The chips shown in that photo are all 10 ns, not 100 ns. $5 per module is very pricey, almost 3x what I paid from independent Chinese IC sources. Long before I found my 10 …

I've plotted out the PII Klamath at 133, 166, 200, 233, 266, and 300 MHz. 133 - 266 MHz are with a 66 MHz FSB, whereas 300 MHz was with a 100 MHz FSB. If the 133/5x CPU is running with a 66 MHz FSB, the memory read speed would, presumably, be linear with other CPU frequencies at 66 MHz FSB. And it …

I have a 6600GT... I am still not sure about 3.3v AGP compatibility because I can't seem to find any reports either way in web searches. I suspect that the NVIDIA HSI / BR02 bridge may be 0.8/1.5v only though. I ended up testing a 6600GT in a 440BX board, which is of course 2x/3.3v only, and it …

Mine also has those odd bugs, my M919 board will only POST if the CPU is configured as an AMD DX4. It also identifies at 160MHz at 50x3, weird stuff eh? I assume the misconfigured CPU type is why the L1 cache mode is grayed out in the BIOS as well. Is your L1 cache mode grayed out in the BIOS when …

What happens if you try running the 440LX board and PII-266 at 5.0 x 66? Prior to wrapping up Klamath testing, I discovered that running the PII-266 on a VIA Apollo Pro 133 (VIA 694/596) with a 5.0 x 66 setting allows for 133 MHz with L2 cache enabled. Chkcpu claims it is running at 5.0 x 26.7, …

Interesting. I wonder what mechanism the 440FX board places over the PII-133 which the other motherboards cannot. It is surprising that 3 chipsets, other than the 440FX, were unable to properly enable the L2 cache of the PII at 2x/66. I suppose such a CPU configuration would not have been a priority …
