can i underclock a 1.4tbird to 1.2???

[Lithium381]

It's just that right now my board only goes up to 1.2, and i'm going to keep it for a little while longer, then i want to not have to buy another CPU, so if i get a 1.4 now, can i underclock it to run at 1.2 for the time being? would i have to unlock it to do that?

If it's unlocked, you should be able to set the multiplier. If I remember correctly, the L7 bridges (the hard-coded multiplier) on the 1.4GHz B part are all connected, which is the same as the 1.1GHz B, which should give you a default multiplier of 11 if you put it into a board that only supports up to 1.2GHz. If it's unlocked, you can then change it to 12.

what's the B suffix mean?

 

[jchu14]

B means the CPU is 100fsb. (C means it's 133fsb)

and A is the original athlon?

B is the suffix for the Thunderbirds that run @ 100FSB (200MHz effectively)
C is the suffix for the Thunderbirds that run @ 133FSB (266MHz effectively)

Although even though your board says it only goes up to 1.2GHz, it should be able to support the 1.4GHz @ 1.4GHz. Like my BH6 ... doesn't officially support my CPU, and doesn't support 133FSB, but it can do it.

well my fsb is locked at 100/200, whatever you want to call it and i've only got a multiplyer up to 12.5.......but a 1.4 266 WILL run on it right?

yeah...it should run fine.

make sure that you have the latest bois update for your motherboard, as a new flash might give you faster processor support.

Try to update ur mobo bios. Most new bios had a higher multiplier setting.

All the post are correct. U can run at 1400 Mhz even ur mobo only have a 12.5X multiplier.

Just go to the bios, load the "default settings". Save & then reboot.
