Hey I have a phenom 2 555 Im using the stock cooler which although Ive read there horrible seems to keep it very cool although my case has good flow so Im sure that helps. I wondering if I can just up the multiplier up to X18 and overclock it to 3.6 without having any issues with heat Im not looking to overclock the *** out of it I just want whatevers left that I can get without any major issues.

I've never had any issues getting them up to 3.6GHz on the stock cooler. They're pretty cool running until you start hitting 18.5 and up. The real fun comes when you unlock them to a quad core AND try to OC them. You need good cooling to pull that off most of the time.

I wouldn't hesitate to start off at an 18x multiplier and go from there. With the stock cooler, you shouldn't be any higher than 60'ish...maybe 65.

Ok I up it to 18X and ran a 50min cpu stibility test on amd overdrive and the temp never went past 37.5'c is it ok to use that as a test?

Ok I upped it to 18x and everything seemed fine then I ran a GPU test and now the graphics card is acting up could this be caused by to low of voltage at the cpu should I up it from 1.3v to something higher?

bump I backed it down to 3,2 ghz and now its running fine anyone have any clue why its not stable at 3.6 could it not have enough voltage?

Up the voltage from the 1.4v to about 1.45 or 1.5v and you should be fine. Why the graphics card acted up, though, I don't know. What makes you think it's the graphics card?

Try the voltage increase and let us know what happened. Do NOT go above 1.5v.

The stock cooler is more than enough for the 555 unless your CPU is reaching the 60c mark.

The 555 does not need more than 1.4/1.41v to operate at 3.8Ghz regardless of the board you are using.

I have an x2 550 unlocked to an x4 B50 and it runs fine with 1.42v at 3.7/3.8Ghz. Your CPU should use less since it is running as a dual core and the fact that it is a C3 revision (runs cooler and uses less voltage than the x2 550).

I bumped it to 1.35v and overclocked it to 3.6mhz. I then ran it on Prime95 for 8.5hours and no errors and didnt go over 44'c so Im thinking its all good thx guys

Well I tryd to up the multiplier to X19 to take it to 3.8ghz and I took it up to 1.4v it wasn't stable and crashed when I started prime95 is there and kind of voltage I should have increased besides just the core voltage?

Well did you manually set all the other voltages?

What board do you have?

Just curious - were you able to unlock the cores? I'm wondering if there's a correlation that if the two cores can be unlocked and be stable, if as a dual core you can get a higher overclock or it's vice versa. You can get a quality dual core that can reach a high overclock and run stable and stay cool or you can get a dual core that has two "good" extra cores but sucks at overclocking even as a dual core.

Not really, the 555 can normally achieve at least 4.0/4.1/4.2Ghz and the same or less as a quad (if unlocked). I dont think the OP is interested in unlocking, it seems he just needed some help to achieve a moderate overclock.

Well I have a biostar A770E motherboard Im a noob to this Ive ONLY touched the core voltage and the multiplier at X18 and 1.35 its stable. When I go to X19 and 1.4v its not Im assuming to go any higher I need to adjust some other voltages correct?

Correct, and not only the voltages but other values as well. I am not familiar with your board even though I have a similar 770/SB710 that should have more or less the same Bios. Anyway you can post a screenshot/link to your Bios?

Sweet, ok first off raise the NB vid to 1.2v and leave the NB Fid at 2000Mhz

Also make sure that you give the CPU at least 1.36/1.37v @ 3.6Ghz (varies), leave your HT Link and CPU/NB at 2000Mhz (not shown in the above pics but you should have it hidden)

Let me know if you need help with any other value/values, your Bios is very different than mines (Asrock 770).

Could I push it up anymore without making alot more heat. Right now at full load in prime 95 it hits 44'c.nIs me not adjusting the NB Vid to 1.2v the reason it wouldn't do X19? BTW thank you for the help

I would have to be in front of your monitor to see exactly why it would not do x19 with the previous settings. Do you have CPU-Z installed?

Ya do you need a screen shoot from that BTW I didnt see anything about the HT settings

On the first Bios pic you have "Hyper Transport Configuration" =)

The HT is set to auto should I change it to 2000mhz or just leave it ?
