AMD® Phenom™ II Overclocking Thread
- Thread starter Big.Wayne
- Start date
I've just changed my Arctic Freezer 7 rev 2 for a Scythe Mugen 2 - I really wish I had bought this in the first place!!
I'm currently running my 965 at 3.825 GHz, 2400Mhz HT and NB. 1600MHz Ram at 8-8-8-24-40-1T.
The Scythe is absolutely massive, but easy enough to fit and really quiet.
It idles under 30 degrees, Intel Burn test brings it to around 48 degrees. So much better than the 70 degrees it was seeing before that!!
I might try and push the clocks up in the future, but at the moment there is no point and would rather have it nice and stable.

The Arctic Cooling Freezer 64 / 7 Pro are really no better for temps than the stock Phenom x4 coolers. They're only rated up to 130w, which is less than a few AMD chips. They're a lot quieter maxed out than the stock cooler though.

Scythe Kama Angle is in. @ 3.3GHz, 1800NB Pime Blends are running about 50 - 51 rather than 57 to 58 (with old Freezer Pro). S&M MMX still pushes it to 55 though. The case airflow was carefully optimised for my old cooler though. I may be able to push temps down further with a little tweaking.
Having said that - I've got a clocking improvement already. S&M CPU (FPU) test used to fail (freeze PC) with NB @ 2100. It's just passed with NB @ 2400. Just going for a longer test and then maybe some Intel Burn...
Unfortunately I very much doubt I can push overall CPU speed higher. Either my RAM, Board or the Memory Controller causes intermittent POSTs at above 300 CPU / Ht frequency.

Are all the stock Phenom coolers the same?
I have a dual-core which I can unlock (tested briefly) but if I unlock, should I change the cooler if I do not OC?

Does the dual core phenom cooler have heatpipes? There are two AMD stock coolers. The one with heatpipes actually isn't that bad.
If you unlock, maybe run Prime Blend and set threads to 3 and see what temperatures it gets to (you can't read individual core temperatures when unlocked but you should be able to monitor overall CPU temperature). If that runs OK and your temps aren't too high then run with 4 threads.
I would say if you go over 55°C you should consider upgrading the cooler. If you hit 62°C or over it's definitely not adequate (and you should stop the test before it gets any higher). The stock cooler can get pretty noisy. I would say that's reason enough to upgrade it.
No reason to spend much over £20 (£30 max) on an air cooler. Xigmatek HDT S1283 or Titan Fenrir are about as good as it gets. The former can be found under £20.
Anyway - whish me luck. S&M is just getting to the test where everything would go pear shaped with my freezer pro...
Edit: sweet. It passed. First time in ages I've been relaxed running S&M. It sat at 54°C most of the way through. Some recent runs had involved me watching the temps gradually rise in speedfan with one finger on the mouse for the stop button and one finger on reset for when the inevitable freeze came. Let's see what's next... 3DMark06 wouldn't run with the northbridge at this speed before. I'll try that soon.

My X2 550BE didn't. Small lump of aluminium with a poxy little fan on top. My Arctic Freezer 64 (first version) is much better, and can handle 3 cores properly.

Right - seems like it's been a good evening. NB overclocked to 2400MHz. Stable in S&M (100% load, medium length test) and 3DMark06 - which wasn't happening before I got the Kama Angle. Plus got my best ever 3DMark06 score with a stock Radeon HD 4850. Good times 
Edit: Bah! The above settings BSODed after about 4 hours of Prime95. Back something stable until I get the time to test again.

For starters mysetup is shown below:
CPU : Phenom II X2 550BE @ X4 (unlocked) 3.5GHz 0926MPMW
Mobo : Gigabyte MA770T-UD3P
RAM : Patriot PC10600 4GB kit
Cooler: Arctic Cooling Freezer 7 Pro rev 2
I need some help here guys, am not sure whats going on here, one of my temp seems not to be correct because its hasnt changed except by 1 degree when i was running intelburn test as well as the prime95 test which I ran for 3 hours. the one in the middle however increased up to 55 degrees. Both testing software are reporting the same info.
I havent actually run the processor with factory settings at all (2 cores and stock speed).

Ok got this B55 unlocked and running @ 3950 - 1.55v. Super pi time of 17.5 secs (probable a bit low due to not having played with the mem yet).
Now I haven't touched any voltages except the cpu v core, what the heck to they all do. Nb is obvious, but cpu to nb voltage =
And pci e overvoltage seems a bit random, there are other random ones too, anyone know what these voltages do and what they can be maxed at?
Will post some screens once I have a prime stable 4G.

Those are the bus voltages and best left alone unless you get the reference clock from 200 mhz towards 300 levels.
There is CPUNB and NB btw, the motherboard NB can be left alone, but to get the CPU northbridge to clock up you have to give it some more juice usually.
Sal, your temp sensors dont like the unlock by the looks of things, have you tried you MB manufacturers program?

I tried the ones that came withe MB but it crashes whan I try to run it. Not sure what I should Do, I was able to run prime test for about 3 bours yesterday and the temp went up from 79 to 80, so am not exactly sure its reporting the correct temp.

I have the same mobo. The only way to get temps is to run prime/occt etc for a good hour or so, then imediately reboot and check the temp in the bios.
Haven't tried everest yet that might work.
Soldato
No ones temp sensors like the unlock. If you hadn't noticed you can no longer see the individual core temperatures at all after unlocking.
I have everest installed but it dosent seem to be reading temps at all.
I ll just run another hour of prime95 and reboot as yo suggested.
I still wonder why its showing 3 temps instead of for 4 cores..
Soldato
The other two temps are things like the motherboard northbridge etc. They're not all CPU related.
Look on your BIOS screen for CPU temperature and see if it matches any of the software options.
Have you tried CPUID HWMonitor as an option?
Soldato
What he said ^
My TMPIN0 is overal cpu temp and the TMPIN1 i dont know, but its always low.

When I went into the Bios, immediately after running an hour of prime95 the cpu temp was about 40 dropping down to aroung 37 later.
Now I have actually disable the unlocked extra 2 cores and I have staock speed and 2 cores and the TMPIN2 is still coming up as 79 Degree, so its either the monitor is not doing something right or what.
I have just ran CoreTemp now and its idle @ 27 but when I unlocked the 2 extra cores Coretemp wasnt getting any reading.
