AMD® Athlon™ II Overclocking Thread

If your looking at Hwmonitor then TMPIN1 should be CPU temp, TMPIN2 is a "dead" sensor and doesnt report a correct temperature, I've included a screenshot of Open Hardware Monitor on my system @ 100% load

Adjusted the Load Line Calibration to 19%, lots of sources on google seem to have luck with that as their LLC value as well. vCore at 1.4 and the large high fluctuations have stopped - now getting between 1.375 and 1.42 at load.

Also bumped my NB to 2250mhz at stock volts.

I'm reasonably happy with this as it has stopped failing prime within the first minute - might try for a lower vcore now and do some long stability tests.
 
I'd give it an overnight run of prime before you go any further to be sure instability doesn't rear its ugly head.

Then you have two options, improve temperatures by trying lower vcore or working towards a higher clock. I'm a clock it until it begs for mercy myself.
 
It seems to be 9h prime stable:

CPU: 3500mhz
Vcore: 1.4v
LLC: 19%

NB: 2250mhz

RAM: 1333mhz
Vdimm: 1.5v

I've just had a thought though: my NB voltage is still on auto and so is my HTT voltage (and chipset voltage if that is seperate). Do those need to be taken off of auto as well?

My HTT is stock at 2000mhz, but my FSB is up to 250. What are the default voltages for these things? I can't seem to view their values in HWMonitor.
 
Ive had a re-arrange of the fans in my case, basically switched all the fans around so air travels from back to the front now instead of front to the back. The CPU is now idling at 28ºc, load at 46ºc. Compared with 29ºc and load at 54ºc.
There is a vent at the top of the case which hot air is coming out of, don't think i've got a fan that will fit the screw holes though.

Also bumped the vcore up to 1.45v to see if it lasts and longer than an hour in Prime95, although again I was playing games and video editing with no problems!
 
Well after tweaking my RAM voltages i'm now running stable at 3.5ghz. Have yet to manage to get the CPU frequency above 3.5ghz without getting a crash.

Will i be able to do that now?

Sleevedaddy: Can you post up screenshots of your SPD and Memory tabs for CPU-Z and a list of what motherboard and memory your using.

Well there's been a bit of an update. Have a read of my other thread please. Really struggling to keep stable.

I've just refered to Wayne's screenshot earlier in the thread as he has the same bios. I've put everything to auto except CPU Frequency @ 250 and Vcore @ 1.425

Running Prime95 now so fingers crossed.

and my SPD tab is blank

I'm using Asus M4A78LT-M 760G mobo and OCZ Gold Ram 2x2gb

Had another mess around with the fans in my case, reduced the temps even further (Albeit only by 3 - 4ºc but every little helps right? :p) and I'm going to leave it as it is for now. Might try and push it further at some point but I've got a 600Mhz OC and the memory is running at its rated speed. :)

Oh and I also get a wonderful cool breeze around my legs now from my PC, the H70 is shifting some serious air! :D
 
Update;

Managed to run @ 3.75 for over 2 hours on Prime Blend, temperatures didn't rise over 45c which im pretty happy with.

Any pointers to get more, or should i just stick at this?

FSB:DRAM depends on your ram, is it rated at 1600mhz or 1333mhz, your better off leaving it as its set for now. I'd give it an 8hr run on prime95 now to ensure full stability before you go any further.

1333 RAM

From my above screenshot does everything look as it should? Is that a decent overclock for a first timer? :confused:
 
Everything looks as it should and its a fairly good OC, mine was an Athlon II 240 @ 3.6ghz.

With your ram overclocking past that point will get a little complicated as you will have to begin overclocking the memory as well which makes isolating a weak point harder.
 
If you wish to push past 250 fsb then yes. This will tell you the limit of your ram. Manually set the timings in the bios along with the DIMM voltage, drop to a 4x multi and push your FSB till you get errors in prime. Increase DIMM voltage until you hit 1.9v and that will be your limit.
 
I think I've managed to stabilise my 3.5ghz Athlon x4 630. Seems that the 2250mhz NB without extra volts possibly caused the BSOD.

I've dropped the NB back to 2000mhz since froz says it doesn't make much of a real world difference. I've also tightened up the vcore on the CPU to 1.375v (which is stock I believe) and it has passed 1 hour of Prime blend, 10 passes of IBT on high, an hour or so on BC2 and an hour on AOD.

Gonna give it an over night run now and then I'll post up some screens - pretty chuffed if it is stable at 1.375v - it hasn't really shaved anything off the 50c load temps though, but I may try higher clocks up to 1.425v.

One question - what is better to do long stress tests on IBT or P95, I've read IBT is better and it certainly gets my CPU a little hotter than P95.
