I just got mine to unlock to a 3 core! Off a tip from a member here in another thread I went back into my BIOS and found "CPU Active Core Control" that mustve popped up when I update my BIOS last week. It had the option for Core0 either enabled or disabled. So I left it on and hit ACC and left the BIOS. When it posted I went back into the BIOS and it showed the unlock like before but when I checked Active Core Control, it now showed Core 0-Core3 each with an option to disable or enable. I tried booting into Windows but it wouldnt just like before but I went back into the BIOS and turned Core3 off and tried again. Works like a charm! Running at 4.014 GHz and seems stable. Bumped my Windows Experience up from 6.9 to 7.1 and I picked up a half frame on my Crysis benchmark.

Cool thing is, Core Temp shows its a Phenom II X3 755!

The only negative is I cant get a temp reading from anything. Speedfan, Hardware Monitor or Core Temp. Im not too worried cause in dual core mode it never got over 34 during Prime95 so an extra core shouldnt heat it up too much more although I did bump the voltage up one click just to be safe.

Hey dude, glad you got that unlocked, and still at 4Ghz, nice!

For your temperature monitor, you can still use those programs, just use the CPU temperature, not the individual Core temps (Best to download Everest Ultimate Edition, and the CPU temperature in the sensors section, will match up with one of the TEMPIN0/1/2/3/temp1/2/3, you can then change the name in Speedfan to -CPU- so you can future reference it). There'll be a slight difference between the the Core temp and the CPU temp (up to 10c), that you can ascertain if you re-lock it then compare the differences, unlock again and you have a 'rough' guideline, or just as a general rule of thumb, don't let that CPU temp go higher than 50c, and if it's below then you've got no worries. 8)

Brilliant OC you've kept there though man.

Thanks bro! It was your post that tipped me off. Not sure why I thought it was in another thread though.

Im keeping an eye on it with CPU-Z's Hardware Monitor but I dont think there will be a problem. Gaming is the heaviest thing I do with this rig so if it maxes at only 34 after hours of Prime95, 1 extra core and 1 extra tick of voltage shouldnt be a problem. Im still under 1.5 Vcore so I think Ill be ok.

Im really surprised I kept this overclock to be honest. I had a lot of trouble hitting 3.5 with my old Athlon II X3 and finally gave up and settled on 3.4 while everybody else was up around 3.7. I figured this ASRock just wasnt up to the task. I think ACC might be doing the extra work for me. Since I was able to get 4.0 stable with it disabled using dual cores, the extra help it gives is just enough to keep it stable with a third core along with the slight bump in voltage.

And I think utilizing the FSB as much as possible and not relying strictly on the multiplier might be giving me a little extra head room as well as does my 800 speed RAM.

I tried different HT link settings but found "Auto" to work best.

I just like the "X3 755" thing for some reason.
Not sure why it only shows up like that in Core Temp.



**Edit

Just played Borderlands for over an hour and my CPU temp was showing 39C so I figure the actual core temp would be around 29C. Thats about what I thought. Granted Borderlands isnt a very CPU intensive game but it still should be a good measure.

Thought I was in this club many moons ago but must of been mistaken

We'll here's my 550BE as B50 which is now sittting in my media/folding rig as only a 3.6Ghz quad folding 24/7. Sitting in a ga-ma785g-ud3h and under a 212+ stopping it from melting.

Here's the highest I've had it and only to do a couple of benchies before I melting it. Being an unlocked chip I had to guestimate the temps

http://valid.canardpc.com/show_oc.php?id=1212120

P.S. Tator if your watching, vnv727's been inactive for a couple of month's. Did ya want to transfer to a new owner to maintain/update/refresh the thread. Seams with a bit of work could be a decent thread again.
post #4168 of 4289
I have my B55 stable at 3.8 but I have my vcore is at 1.56 load and 1.524 idle. The highest my temps go after 20 passes of Linx is 54 and running p95 it only goes up to 51. I'm worried about the high voltage though. I'm used to seeing vdroop but this vbumo is scaring me. I have both LLC options enabled in bios because without it my overclock fails quickly.

Should I be worried about having the vcore so high? Would a better mobo let me drop the vcore and maintain a stable OC? I'm itching to get a better mobo because this voltage fluctuation scares me some. Would also like the possibility to sli/crossfire down the line. I wont be a BD early adopter.
post #4169 of 4289
Well it depends on how long you want your chip to last..

I ran my B50 @ 1.55 for 6-9 months straight and at time ran 1.65 for suicide runs and 12 months later its still running fine folding @ 3.6 with 1.45 volts and never misses a beat but there's less chances of lasting longer than 2-3 years after such volts
post #4170 of 4289
It is harder on your gear, both CPU and motherboard but guys like us will be on our 3rd or 4th upgrade by the time it finally dies. Im on my 3rd CPU in a little over a year. Its a sickness.
