AMD sempron 145 unlocking and overclocking help!

post #1 of 13
Thread Starter 
computer specs:
motherboard: MSI 760GM E51
processor: AMD sempron 145 2.8 Ghz
4 gb ram
nvidia geforce 1gb graphic card

so right now i have unlocked the sempron 145 and the computer now tells me its a athlon X2 4450e 2.16 Ghz.
so can i now overclock the athlon from 2.16 to something like 2.5Ghz? or should make it a sempron 145 2.8 Ghz and OC that one to like 3.3Ghz or something? can i both unlock and overclock at the same time?

You can do both unlock and overclock at the same time?

yes you can. I'm running 4.2 Ghz on my sempron 145 unlocked. I wouldn't say mine is 100% safe overclock but I really don't care what happens to this chip.

that is odd, the sempron should retain its clockspeed when unlocked.
If it was 2.8 ghz as a singlecore, it should have been 2.8 ghz as a dualcore too

please check your full load clockspeed by downloading cpu-z
search for it in google, its free

i actually bought this computer used and the old owner said he had unlocked it. so the cpu-z tells me its 2160mhz, bus speed is 240mhz and multiplier is 9x. so perhaps the old owner has underclocked it?? but the question now is that the multiplier can be changed all up to 14x and then it would be 240mhz * 14 = 3360mhz.. do you think my computer can handle that?
post #8 of 13
get the cpu multiplier to 14x, and the bus speed down to 200.

That would be the default clock speed of the unlocked Athlon II 4450e so its perfectly fine.

14 * 200 = 2800 mhz dualcore

when i am in bios i can only change the multiplier not the 240mhz
post #10 of 13
Did you try stressing it to get the multi up?

If you have cool n quiet on it will drop the multi to save power, although it should show the x14 multiplier in the bios.

You should be able to change the 240 unless something is wonky with your mobo/bios. What motherboard are you using?
