the power this chip draws is too much.. sked the mosfets cant take it. if thuban/deneb i dont really care... 1.55v for daily usage FTW

the turbo core for 1core how high eh? i also donno  laugh.gif

[attachmentid=2560367]
manage to get this speed with "still safe vcore"
but it wont last survive any benchmark i think. no time to oc now  sweat.gif  sweat.gif

i guess my 8120 is the limit. increasing more vcore also wont help. yours also the same i think. just you luckier then me. got 300Mhz faster

I have got a 990FX board running Phenom II 1055T (3.5GHz) with it. I guess I'll wait till Piledriver for the next upgrade.

it will delay a year later.... tongue.gif

about the oc.. i think it is cause by the mobo... need more phase power to boot higher clock... just guess only...

yup bro, unless ur a die hard amd fans. not much improvement still ok, but thuban/deneb pwns fx clock to clock in most tests.  sweat.gif

but still, fx are fun chips to play with... only concern is power draw & one need a mobo with strong pwm.  wink.gif

Noob here.

GA-M55S-S3, AMD 64 X2 4200+, Kingston DDR2 2G.

There plenty of advice on what to do with multipliers and dividers on CPU, HT etc, but on my mobo, there's only the "CPU clock ratio" (x11) - and no other options.

All the other adjustable BIOS options are to do with voltages, ranging from +0.025V to +0.37V.

I've increased the "CPU frequency" to 218Mhz, but any higher it will not post.

What can I look at next?

lower your memory and lower the hypertransport as well... search google read more oc guide

There are no options to lower the memory multiplier or ratio.

So what exactly do you mean by "lower your memory".  As I said, there are no other multipliers to change on this mobo BIOS.

These are all the options I have:

cpu frequency mhz: 200 - 500
pcie clock mhz: 100 - 200
cpu clock ratio: 5 - 11
ddr2 voltage control: +0.025V - +0.275 white +0.300V - +0.475V red
chipset/pcie voltage: +0.025V - +0.375V
ht link voltage: +0.025V - +0.375V
cpu ht-link voltage: +0.025V - +0.375V
cpu voltage control: 1.5500V - 0.8000V
*
No options means your board doesn't support overclocking.....
