66x1.5 vCore 4.49 V (4.2 was too low). Double peltier (TEC). HR-02 Macho on TECs. 2x512 double sided SDRAM gave me maximum amount of visible RAM: 128 MB. CL2 in bios and turbo settings. SYS,PAGEFILE and SPI discs. Don't know real temp while benching, but it should be <25 *C.

Added a YOUTUBE video :D

copywaza could have probably saved you an hour :D

Poland ludek says:

haha :) when I use copywaza at SPI 32 MB, I'm having "Not exact in round" error. (when using OCX SPI Tweaker and set size in MB eg. 256 MB and single file size 1024 kB = guaranteed failure) i'm doing this wrong for shure. At these settings a SPI 1 MB test works.

BTW. I'm going to SPI 32 @ 486 DX and DX2. I Have Socket 3 motherboard with EDO rams. It'll take... maybe a week :D

More, much more :D

 

Nice old school benching, kepp pushing!

Prepare for 2-3 months, UPS needed 140%.

Russian Federation Antinomy says:

Maybe less than 2-3 months but definitely over a week for DX/DX2.

In all fairness he didn't mention which DX, might be the 25 or 100Mhz, but remember Karl's 50 days W1024? It's gonna take even more for SPi32.

Russian Federation frag_ says:

I think ~3 days is possible for DX2, and ~5 days for DX =)

Poland ludek says:

UPS is actually not bad idea, I was thinking about it :) I bought a two special high-performance, hi-end, TOP motherboards with EDO. Slow SIMM memories would make it two times longer. I have DX33, DX2 50, DX2 66, cyrix 66, AMD DX4 100. Don't know if are all of those on hwb database. Should be interesting BTW, which is faster DX2-66 or Cyrix 66, hmm... I'm counting on less than a week @ DX2-66. i386 - this one should count SPI32 3 months or more, sadly I don't have proper motherboard... but i still have a i286-25 :D Will be interesting for shure :D

Russian Federation Antinomy says:

GENiEBEN, Karl used an SX - no FPU. ;) that's a huge difference.

frag_, don't forget that socket 3 bus width is twice less than socket 5/7. Big difference for Pi32. And he should build a specific config to achieve best results.

ludek111, Cyrix 486 CPUs are weaker than Intel/AMD. Except the 5x86 series which are a whole different story (they could be called 6x86 beta).

 

I see an interesting competition - make Pi32M in less than 4/3/2/1 weeks. And categories for SX/DX/DX2/DX4 and a separate one for Intel ODP/AMD X5/Cyrix 5x86. Due to conditions, there shouldn't be a month limitation, more like an ongoing. And CPU photo required to verify the category was chosen right.

And there is a thread about SPI 32@i486. LINK
