AMD® Athlon™ II Overclocking Thread

[slagsmal]

Got my x3 450 today

wasnt quite stable so dialed it back to 3.7ghz, its looking good so far.

Very Nice!
I've got to stop checking this thread i'm getting the overclocking itch again.

Just out of interest what Stepping is your 450?

I didnt think to check, it turned up a week late with a bent pin so I spent some time stressing out with a lamp and a knife. It was an OEM one from a well known auction site.

Its a bit annoying as I know I could get more out of it but my motherboard is balls and wont let me overvolt it. It says in the manual that it doesnt support overvolting phenoms, I had a athlon 64 x2 brisbane a while back just to bench and I could overvolt that but not this. Time to get a decent motherboard I think, but mabye I should wait to see what happens with am3+

Im confused as to temps that i'm seeing under load. Where should i be looking

HW monitor reports CPU at 60 but core temp is 51.

Coretemp reports it at 51

OCCT reports it at 51.

If im being optimistic and believe the lower temps i could push for a slightly higher OC.

thanks guys![/QUOTE]

It will be 60°c.

My sympathies are with you, Hex. I have a late Athlon II x3 445 which is the same stepping as most 450's (i.e. NADHC AD) and its a PIG.

Mine's VID is 1.4v and it needs 1.475v to be stable at 3.5Ghz. I decided to stick with 3.4Ghz at 1.45v just so my fans don't ramp. Temps not really problem but I hate even the slightest fan noise if it can be avoided. TBH the difference 'tween 3.4 and 3.5 will never be noticeable outside of b'marks. Shame though as all my past AMD cpu's were gem oc'ers.

Pretty sure mine was the same stepping code. Same 1.400V VID as well (yet it was stable at stock on 1.3V).

Wouldn't clock for toffee however, took 1.425V to get 3.5GHz stable, but only with the memory running 1333 with slack timings. Any movement on the HT, CPU-NB, or ram timings and you could kiss stabilty goodbye no matter the voltage you threw at it.

Anywho it's going back for a refund today as I'm sick of it, and i've snagged a Phenom II 720BE for beans to replace it.

@slagsmal - Any chance of running LinX, 2048MB, 20 loops. Should take under an hour to do.

Bear in mind this is on stock volts, will be trying it on a board that will let me adjust the vcore and unlock cores next week.

 

[HeX]

Excellent, looks like you got a good one there

CACAC

I got the 4th core and l3 cache unlocked, passed 20 loops of linX. I would clock it up a bit but with it unlocked coretemp and hwmonitor both show temp as 0.
Don't suppose anyone knows of any other alternatives?

 

[Uriel]

Unlocking always stops core temp readings. You can still see the overall CPU temperature in Speedfan and HWMonitor.

For me it's Temp1 in Speedfan and TMPIN0 in HWMonitor.

 

[slagsmal]

Ah thanks I see it now, I have one called CPUTIN on hwmonitor.

Heres a screeny of it unlocked

do I need to take this to the phenom thread now?

 

[Uriel]

I think that's where Big Wayne (where is he BTW?) wanted my Athlon X2 once I'd got the other cores and cache unlocked.

It's like the playoffs...

Hi, can I ask how you managed to get the HT Link at 2160MHz while having the FSB at 240? Because I have the X4 640 too, and I've got the FSB at 240 like you, except my HT Link is at 2400MHz..

Would it be more stable at nearer to 2000MHz like you have it?

I'm putting 1.4375v into it at the moment, but not sure if I should have some more in there, also considering you have yours at around 1.47~ and the same FSB as me :/

Help!

drop your ht mutiplier down to x9 then you will get 2160

In terms of stability, people tend to find 2000 is the safest bet but a lot of people manage 2500 with the right voltages set

Being trying to overclock my X4 640 after I got my new Hyper 212+ cooler.

Can't seem to get it any higher than 3.6GHz on 1.525v. Temps are fine, don't go higher than 45c load. Is this the max I can go do you think? Tried various combos of voltages etc, but nothing

 

[sunlitsix]

3.6Ghz is all that I can get stable with my X4 640 too, thats at 1.4v.
The best I've managed though is 3.9Ghz which was bootable to windows but it crashed as soon as any tests begun!

 

[azazin]

i can only manage 3.5ghz, if i so much as change the frenquency by 1+ it will crash on boot, however, at 3.5ghz its stable.

can someone tell me what to change so i could possibly hit around 3.7ghz or 3.8ghz?

Thanks!

Yea after a bit of reading it seems the X4 640's top out at around 3.6Ghz with 1.4-1.5v. Most of them anyway.

Still a 20% increase anyway, and the hyper212+ keeps it nice and cool anyway!

 

[sunlitsix]

Have you attempted to unlock your X4 640 at all? Might be worth giving it ago!

 

[Nymins]

I noticed it was possible to unlock the L3 cache or something. I tried going into the ACC or whatever and setting it from "Disabled" to "Auto", but it doesn't do anything.
