@7.5x100MHz the "Tualeron" looks awfully similar to the Coppermine Pentium III. Are there any timing differences or anything else that would explain why they score so similarly IF [/u] the "Tualeron" has Data Prefetch Logic? Or does this benchmark support my hypothesis of the "Tualeron" actually …

You may well be right, I don't know. There is an article online that attempts to prove that the 13 micron Celeron does not support DPL but the way how the benchmarks are set up does not convince me. https://www.realworldtech.com/data-prefetching/ What I would for example like to see for this …

is it possible to tell if this slocket is 133MHz capable and fcpga? it doesnt seem to be in that guide but does look similar to the one marked as "AA370P (marketed as Matrix & Evercool) 370CPU rev 1.0 FCPGA Coppermine / 133 / auto voltage / no voltage clamp " - however a few others look similar too …

Yes, the date is likely a safe indication.

This mindset completely disregards the improved drivers and the fillrates. I don't think any enthusiast in 1999 held off and waited for the P3 867+ to come out so they can max out the now-2-gens-old 3d hardware they just upgraded to. I'd throw a V3 in the P2 300 myself. With your mindset he could …

A Pentium II at 300 Mhz is not powerful enough to get the best out of either a Voodoo 3 or a fast TNT2 as far as I have seen. Not worth to 'upgrade' imo.

We -have- to know, right ? :-) Btw, RTM-520-39D is a frequency generator. Unless it has a PLL on board it is not the chip that 'produces' the multipliers. Is there a smaller chip with 4/8/10 legs in that region ? ps SL356 is a later fsb 100MHz Deschutes. An older 66MHz version is probably needed for …

I'm not worried, just curious if a board with 1.5 multi boots with an unlocked Deschutes. It does not seem a common combination and I don't think I have ever read about somebody trying it.

The table above also has a double listing for 2x (all low & all high) which is the same as in the Intel specsheet for Pentium Pro. The clock multiplier on your board is maybe a different design. Can you see what marking is on the chip ? The datasheet may provide answers. Filename Pentpro.JPG File …
