a question about clock multipliers...

[locutus12]

i havent had a chip whose multiplier can be changed for a long time now and im wondering if im missing something ???

first i had a 2800XP that i couldnt alter the multiplier on,
then i got an Asrock 939 and an A3000+ Venice core which i couldnt alter the mutiplier on,
now i have an opty 146 but still i cant change the multiplier ??? should i be able to ? is it hit and miss ? or are they normally just locked these days...

The A64, X2s, optys and C2D all have locked multis.

no, they are normally locked these days. The only unlocked ones are the fx and extreme edition cpu's.

edit - arggh, beaten to it.

You should still be able to change the multi downwards though

300ishx10 should be possible on a 146. Mine hits a wall but is perfectly stable at 295x10 at 1.475v.

No they dont, my 3700SD has an 11 multi but i run it at 10 so i can push up the speed of my memory even when using a 333 divider.
260 x 10 = Cpu speed of 2.6 gig on a 333 divider giving mem speed of 217mhz at 2.5/3/3/7.
That is faster than having 236 x 11 on a 333 divider cos the mem would run slower although the Cpu speed is the same.

fine, locked upwards.
