Hi i overclocked my phenom II x2 550 into a x4 b50 and am trying to overclock it a little bit with the stock heatsync and fan. I set the clock ratio up to raise my clock speed to 3.4 Ghz up from 3.1 stock. Also i should add that i was only able to unlock 3 cores out of the 4 in order for my PC to boot up. so i have 3 cores at 3.4 Ghz.
I did not raise any voltages on the cpu in the bios however my system seems to be running stable regardless at 3.4 Ghz. What is considered a stable temperature considering im running the stock cooling system. also when i ran the prime95 stress test my system shut off I saw temperatures for the cpu get up to 63. should I increase voltage or not try and do this slight overclock with stock cooling system?

The hyper212 is a good match for you. The bonus with decent aircoolers is a thing called bleed. While a good portion of the exhaust is directed at the rear by the fans airflow, there is still some that 'bleeds' out the sides of the cooler. So this will put airflow across the Northbridge chipset without need of further cooling. It's not as effective as a downward facing cooler such as a Noctua NH-C12/14 but still does much better than any AIO.

How much OC you'll be able to get will be determined by your temps on the mobo, and the voltages you run. The lower you can keep the voltages, the better. You'll hit voltage, stability limits on that mobo long before you hit cpu limits.

Max core temp is 70C for the Phenom II X2 550 BE (rev. C2).
But enabling a disabled core will raise the temps more. And if the core was disabled due to excessive heat, even more. I would not try to take the vcore any higher unless you have a very good motherboard with adequate heat sinks on the VRMs and use an aftermarket cooler.

in regards to the adequate heat syncs on the VRMs how do I check the quality of these? I have a gigabyte ga-ma770t-ud3p

this is what is says on motherboard specs: Advanced 8+2 phase CPU VRM power design for AMD high-TDP 140W CPU support

If this (or one of the other revisions listed) is your board, it has NO heat sinks on the VRMs.

However, if you were to add some after-market heat sinks, the rest of the board's specs look pretty good.

The voltage regulatory circuitry is mainly that line of little caps and the small black cubes on the left hand side of the socket. On good OC motherboards, not only will these be covered in a considerably large heatsink, but they'll also be a much better heatsink on the Northbridge (that weak aluminum square under the socket) and another large heatsink on more circuitry above the socket, and all usually linked with heatpipes. Your board has no heatsinking other than the Northbridge, so any OC will leave all those components at the mercy of the cpu cooler.

ok so I mentioned that i recently upgraded to the phenom II X4 1060T that i unlocked an additional core on . so im running 5 cores at default clock speed. I ordered a EVO 212 aftermarket cooler for the CPU which is on the way. will I be okay to overclock my CPU on this current motherboard with that setup? or do i need to get a cooler for the northbridge as well? i didnt even know something like that existed. thanks for the help. obviously I am doing all of this because I have an older system and wanted to upgrade as far as possible without replacing a motherboard.
