AMD® Athlon™ II Overclocking Thread

I've unlocked my fourth core (435 x3) on an msi 770 c45 with cheap kingston ddr 3 1600.

Windows post fine and I get the L3 cache too. A few seconds after boot aero crashes and as does the ati display driver.

Now if I disable the 4th core manually I still geth the l3 cache on the other 3 cores. It also does like my ram running at 1600 with the 4th core but is fine with just 3 cores active.

I'm running it at stock volts.

Any ideas guys

Hi drogon, I've not had much experience of unlocking but from what I have read in some cases a core/or cache can unlock but not work correctly no matter what you do? . . . . and in other cases the flakey core/ or cache works fine once you boost the relevant voltages! :)

Not much more I can add really apart from have you tried starting off using your AMD® Athlon™ II X3 435 as a triple core and overclocking that before dabbling in ye mystical unlock? :D
 
Well without the 4th core I can get it stable at 3.6Ghz 1.45 volts.

It doesn't matter how much voltage the 4th core just wont play :(

I've disabled cool and quiet, find out what the other thing is lol!!! :D

Thanks guys.
 
I can change my multiplyer in the bios but the maximum is x15.5 which is the default!? So im stuck changing my FSB speed?

MB - Asus M4A785TD-M

I have installed latest bios n have a Phenom II X2 550 BE

Am I missing a BIOS setting?

Hi Guys! . . . thanks for your comments! :D

In case I didn't make it "abundantly" obvious already I'll just state again that I am a slow overclocker . . using affordable equipment (inc quiet air cooling) and I'm only submitting "proven" stable results! . . . anything I post up in this thread will be realistic for 24/7 usage by any other "mortals" at home :)

I can say that MHz numbers can be quite misleading and even running at a "humble" speed of 3.5GHz the Propus quad-core is "computationally" the fastest 24/7 computer I've ever used! :p

There is still more headroom in the chip for extra speed but it's taking me a while to "validate" the stability . . . there will be no ragged-edge suicide results here, just solid, realistic 24/7 clocks that can be reproduced by anyone at home who is also using affordable kit alongside quiet aircooling . . . . . stay tuned! :cool:
 
Haha, well thats good. I appreciate 24/7 clocks a lot more to suicide shots :)

I did however expect this to hit higher levels. Especially when competing chips (i3s) are easily hitting over 4GHz 24/7 shots from what i have seen. Not to mention the bloomfields!

Anyway, keep up the good work. Is there any way for you to measure the power draw as well btw? Would be interesting to measure power efficiency before and after overclocking. Optimal clock perhaps?
 
These are athlons, not Phenoms, and it's stock 2.8ghz, doubt it will go higher than 3.6ghz, he's also OCing on 40quid mobo : ).

And not like there is much difference between 3.6 and 3.8-3.9 anyways, 200-300mhz is not such a big deal anymore now that CPUs have 3ghz stock clocks and heck knows how many cores. Jump from 3.6 to 3.9 will bring 5% real world increase maybe. At this speed it will also beat 4ghz i3 already in multi threaded apps on which it's aimed.

Great chip but then still I'm not sure if I could justify this over 435 at whooping 30-40quid difference.

Hehe Trunks9486! :D . . . I'm so sorry I am the tortoise of the overclocking world! :o . . . I don't know how to whack a new processor in and achieve it's max stable overclock quickly . . . also having been on LGA775 for three years it's taking me a while to get a good feel for AM2+ clocking, three/four months with it and I am still fairly nOObie heh! ;) . . . Apart from the Prime Blending I am using the machine as my workstation and giving it plenty of real-world usage, just in case there are some little "gremlins" that I'm not picking up with the Blending/OCCT/IBT/LinX'ing! . . . . I gotta be sure the clocks/info I share is good and robust! :)

Anyway thanks for the kick up the butt, I'll try and get this testing done as quickly as I can, apart from the stability testing there is also the benching, it's more time consuming than it looks! :D . . . . here's a little Fritz to "nibble" on . . .
