Hi, I have such CPU installed on my Gigabyte GA-MA770T-UD3P motherboard.
I've unlocked two more cores without any problem but I'm not satisfied with my OC result. I can only get x19 multiplier (3.8GHz) at vcore 1.425V. I'm overclocking only by multiplier.
It doesn't boot on any higher frequency with that voltage, also it doesn't boot on that frequency on lower voltage.
I tried to increase CPU-NB voltage but it doesn't help. Is there anything I can do or is this CPU just weak one?

You can up the CPU voltage. Try 1.435v and see if it boots.

You will need 1.45v for 4Ghz. Have you checked to see if your 2 unlocked cores are stable?

I would say "You need 1.45v for 4.0ghz". I have seen Phenom II x2/x4/x6 need 1.55v for 4.0ghz.

You can increase the Vcore more. My personal safety limit is 1.55v on those chips. Just make sure your temperatures don't exceed 70c (62c is the safer limit to adhere to).

Since I've unlocked cores, CPU cores sensors doesn't works... It always shows 0°C. So I can only see the whole CPU temperature, and now it's about 59°C in stress, so I'm a little bit afraid of increasing voltage. I have CoolerMaster Hyper TX3 cooler and I will apply some better thermal paste soon.

Yes, all four cores are fully stable. I'm using this CPU unlocked since 3 years and I started to overclock yesterday.
Now overclocked to 3.8GHz, I've played 20 hours BF3 on 64 slots servers, ran IntelBurnTest many times and it was stable. But when running OCCT I get BSOD after 40 seconds... But I really don't care because it's stable in games.

You might want to pick up a coolermaster 212 plus or evo. The tx3 is a pretty weak cooler. It couldn't keep my athlon ii x2 cool enough when overclocking either

It's me again. I have replaced thermal paste to Arctic MX-4. Now I have really nice temps (about 52°C in stress), so I increased vcore to 1.5V and CPU-NB voltage to 1.325V and that didn't give me stable 4GHz (BSOD on IntelBurnTest).
I don't want to set higher voltages so I must stay with my 3.8GHz. My max stable is 3.9GHz but I noticed that on that frequency my OS (Win8) boots about one minute longer. That's weird.

how about, if you try something like these setting i did one's?

but, try lower those corevoltage's...

Holy cow man! A 6 core @ 1.536v's on a MSI 760 mobo......

Be very,very careful of those VRM's!

dont scary about that

*i did one's*
i had asrock 970 extreme 4 with one 80mm fan one VRM and one 40mm on NB
then i sended my mobo to warranty (1394 chip melted, almost immediadly when i was bought it (i sav that on june 2012)
i bought msi 760 to my second mobo
and now, i have my asrock back (3.8Ghz 1.45V x4)
and msi is gouing with phenom II 545 x2@x4 when i get graphics card.
Byt hey,thanks you remembered me, i have to chance my motherboard information

For a reference my 910 needs almost 1.4V for 3.3 GHz.
Although That may be stymied by the fact that I am overclocking on one of the worst MBs you can oc on.

i know your feel, but my friend reached 3.8Ghz with that motherboard non-FX version (CPU was if i remember right, phenom II 945)
but, it's that 40€'s asrock what you can use with athlon 64 and latest 95W fx-prosessor
asrock, it make's so weard mobo's that you are so impressed that

I used an 880G ASRock before my current Asus motherboard.I ran it up to 4.2GHz X6 @1.5v for 2 years before a fly landed on a transistor under full-load and shorted it in a puff of smoke and smell of frying insect.

Was a good board. Definitely had to have air on the VRM heatsink though.
