AMD PHENOM II X2 555 AM3 BLACK EDITION

nope speedfan just comes up with a not responding error.
Everest seems to pick up temps though.

EDIT : now even everest isnt showing temps. although prime95 wont run core 3, and WIE keeps crashing, so disabled the core and see how stability is.

cores 0,1,2 are all enabled and its run prime95 for 15mins and temps seem to level out at 59C (if everest is right) will give it 30mins if thats ok then will do some benchmarking, it did pass WIE (which i know isnt acurate scores but find its one of the best tests for stability as the slightest flaw seems to crash it) and scores all jumped up.
 
it now seems to be running stable as a tri-core 3.8GHz phenom :) all i have done is unlocked the extra core and upped multi to x19, i did try to go for 4GHz before i unlocked any cores and that wasnt stable at all. the lack of ability to monitor temps well scare me from doing an overnight prime95 run though, normally i use OCCT as that will stop when it gets to a preset temp, but that refuses to load once the chip is unlocked.
the vcore is on auto, it goes from 1.408 to 1.424 underload, i believe this is the max safe voltage for this chip? if so, is there any way of getting to 4GHz if just upping the multi to x20 doesnt prove stable?
 
ok, sorry for the amount of pics, but i dont really understand all the scores so thought you might be able to give advice as to whether the gains seem about right.

Cant seem to get it stable at 4GHz though

temps aint the issue, its running at 55-57c in prime now and even lower with everests stability test, so not sure why it wont hit 4GHz, but 3.9GHz Tri seems to be very stable :)

Just luck of the draw probably.

Mine will do 4GHz quite easily yet I imagine 4.2GHz will be much harder to reach.

Given the price though a 3.9GHz Tri core Phenom II is certainly good value for money.
 
Had mine at 4.2ghz on water since christmas solid as a rock, the CPU northbridge seems a bit crappy though perhaps that's why it was sold as a dual.
 
For most AMD CPUs you will be given a range for maximum operativg temperature. It usually starts at 55°C and goes up to 62° for Phenom II X4s and 70°C for X3s and X2s.

The lower figure seems to be an instability theshold and in my experience it's really hard to fully stabilise Denebs over 55°C. I believe that the second figure is a safety limit.

Phenom IIs love the cold. Seen some published results for a C3 Deneb on LN2 of 6GHz+ on only 1.4v.

Example of an X3 spec with the limits shown: http://www.cpu-world.com/CPUs/K10/A... Edition - HDZ740WFK3DGI (HDZ740WFGIBOX).html

well its been running fine for a few days now @3.9GHz Tri-Core, and on the games i thought were running nicely on my old cpu, seem to be a lot responsive, im not sure if this is actually real or just me thinking it, but i seem to be getting better scores and doing better since upgrading the chip so maybe it does make a difference. very pleased with it overall, will look at getting a nice cooler for it so i can get the temps down if you think it should be running nearer the 55C

If you're over 55 celcius, temps may be an issue. Get the temps lower and it might clock higher without increasing voltage.

i think you might be right, prime95 was getting it close to but not to the 70, but IBT pushed it over the 70, and this was when i dropped the clock to Tri-Core 3.4GHz, so i fear temps might be part of my issues, although i dont think my particular chip will go to 4GHz on this board with this ram :( but the high temps could offer an explanation as to why i was getting issues in some games.
 
sorry to reserect this again, but when it says 1.4v is the max, does this mean it is the max, or would going over it a little be ok?
thing is, like i said im stuck at 3.9GHz and wondered if maybe it just needs a little vcore bump, but i have gone up to 1.4v already.

I have read that the general consensus is:

1.4v max on stock cooler (+0.02v should be fine though)
1.5v max on decent aftermarket air cooler
1.55-1.6v absolute max on water.

There may be more room at the top end but with the stock cooler I wouldn't want to push anymore than 1.4v for long term use.
