6 year and 2 months ago – 3х moltiplier is possible for mmx 166?

TAGG says:

6 year and 2 months ago – Worked fine for me, also for HAVLI: http://hwbot.org/submission/3804103 Heven't tried 3.5x since i don't need it :)

Some MMX have unlocked multiplier up to 3.5x. I believe the PPGA models are unlocked, while CPGA are locked.

GRIFF says:

6 year and 2 months ago – I'm checked one or two of my 166 but not work with 3x. need of check another cpu's...

Gumanoid says:

6 year and 2 months ago – It's impossible. 166 has a maximum multiplier 2.5x. Go confirming video. I have 5 166MMX and no can mo 2.5x multiplier. I do not see any problems making the result at 233mmх and show on the photo that I used 166!

TAGG says:

6 year and 2 months ago – @GRIFF try some chips made before week 40 of 1997, around that time it seems that the multi has been locked :)

@gumanoid Here you go: https://youtu.be/evxXzNIdlMU  (will be fully uploaded in about 1:30h) you can clearly see the week 35 chip does 200MHz whith the same settings as the 44 does 166. Just so that you know: if you upload a better result with a 166 i'll also ask for video proof... There are a couple of old threads where you can find clues that not all MMX 166 are locked just google "pentium mmx 166 multiplier" and do some digging there have been several people who managed to get these chips to 3x... Please do some reserach before accusing people of cheating

Gumanoid says:

6 year and 2 months ago – and what should I see on this video? I did not say that the board does not start with jumper set to the position of the multiplier of 3x. it starts but the multiplier is still 2.5x. You can set 83MHz FSB and 2.5x multiplier and giga will show 200MHz speed. I would like to see the launching of windows and cpu-z with DMI=0

TAGG says:

6 year and 2 months ago –

You can see the difference in multiplier... as you can see FSB is 66MHz for both, I even show the jumper settings, with the old MMX it shows 200MHz (66x3) and with the new one 166 (multi is set to 3 but stays at 2,5)...

3.5 multi works with my 166

6 year and 2 months ago – no more questions

GRIFF says:

6 year and 2 months ago – Thanks Tagg. I'm find two cpu's with unlocked multiplier one is the week 36 of 1997 and another week 40 of 1997. very very nice)))
