Re: Q: EDO vs. FPM - how to tell which is which

Its easier & faster to just try it on some 486 board that only supports FPM's.

I've done some testing with P-233MMX on Gigabyte GA-5AX oc'ed to 250, 300, 315 and 330MHz. 330 is only 3dbench stable, Quake crashes almost immediately after starting demo1. Results for Pentium-MMX and K6-3 are added to the spreadsheet.

My motherboard supports max FSB 83MHz so I can get it up to 292MHz at 2.8V - but this isn't fully tested, just for the benchmarks. From what I read so far, it usually needs around 3.4V to ran at that speed - but this is different from CPU to CPU, some are better some are worse.

I agree. So I took a 12cm fan, cranked it up to about 2700RPM and mounted it over the cpu for the purpose of this testing 😉

I think 1.06 is the latest shareware. I guess 3Dbench is more of a gaming benchmark then just a CPU one. In the past I never tested it with different video cards and it can make quite a difference.

Now it does explain 😉 Your results are missing from the spreadsheet - so with the ones in it, it looked like Ali5 is slow. What Quake version did you use? With v1.06 I get 53.5 fps (233MHz and Voodoo 3 3000 PCI - didn't test it with TNT2 M64).

Explains what? Comparing P-233MMX @ 233MHz VX : Ali5 - my system has higher score with older VX chipset and a PCI card. I wanted to get a Ali5 board to get higher FSB for OC, but I guess in the end its not much difference for Pentiums.

I'm interested in undervolting because I think I don't have good enough cooling for the cpu. I'd like to do some OC with it as it seems I might have a nice sample. I don't have a multimeter. But I'm thinking on getting one - to salvage a 386DX board that had a battery leakage - now the cache doesn't …

It gets so hot you can barely keep a finger on a cooler (its a really small cooler without a fan). Anyways... I dig the computer up to try and do some overclocking, checked the settings and this 233MMX was set to 2.1V and ran Win98 just fine. Changed the FSB to 75MHz == 266MHz and I had to raise the …
Pentium MMX SL27S undervolting
Posted on 2013-09-01, 00:02
I'm wondering if anyone has done any undervolting and what are the experiences? I've tried with 166MMX and 233MMX and they both go down to 2.0V and run stable. The 166MMX even overclocks to 208MHz at that voltage. And this gets me guessing if this is normal or the jumpers on my QDI Explorer IV board …

Before MSCDEX you need to load some device driver from config.sys - you can use any "generic" driver for ATAPI CD-ROMs (Mitsumi, Oak, ...). You can get this one as it has the smallest memory footprint (5kb) - VIDE-CDD.ZIP I have an ISA ATA controller from 1993 that loads CD-ROM just fine. For those …

Depends what you want. For DOS almost all VLB video cards should be OK. For Windows acceleration ET4000AX is not good. CirrusLogic and S3 were quite popular on VLB as they were quite fast and had quite good Windows acceleration. ET4000 W32 & revisions were on ISA, VLB and PCI buses... good for DOS & …

When I commit, then I go ALL in 😉 But seriously... I'm still on the hunt for 486slc, that I used to have back then. It was 33MHz and from my memory, it's speed was between a 386DX-40 and 486DLC-40.

What do you guys recommend... I currently use Voodoo3 AGP and PCI versions - AGP on P-3 833 and PCI on P-1 233MMX. I was thinking on getting a Voodoo2 or maybe Voodoo Banshee. What is more compatible with glide titles: V2 8MB, V2 8MB SLI, V2 12MB, V2 12MB SLI, Banshee 16MB? Can someone rate these …

But I hope, that in some, not too distant future, I'll have a room dedicated to …
