Anybody overclocked the 550 be to 4 ghz

[huntsman]

just wondering if anybody got the amd phenom 2 x2 550 black edition to 4ghz running stable if so what voltage, multiplier and fsb settings you got on. Also what are the temps of it and what cpu cooler you using. im thinking on overclocking mine to 4ghz its currently at 3.5ghz and on load the temp is 54, using stock cooler. Gonna pick up a aftermarket one prolly the core contact freezer sounds like its a good one and give it a shot.

core contact would be a wise choice overclcker has gotten close but not on the stock cooler ...... A dark knight I believe

 

[huntsman]

what you think of scythe mugen 2 ? sounds like its one of the top coolers out there.

 

[xtc28]

CCF
I havent been impressed with the mugen 2 very much

hmmm ok and i just got back from micro center and i got the titan ttc nk85tz for 43 buck with tax. I have also seen that its rated number 1 on frosty tech so i went for it. Normaly its would of been 55 so good thing i got it, didint even know it was on sale until i got to the cash register it sure made my day. And i also looked at the mugen 2 which was 45 with out tax and the hdt s1283 which was 43 with out tax.

I think it should be a good cooler, What do u think bout the titan its almost like the core contact freezer.

Itll be just as good if not better

you guys might be interested in this site. and yes people have hit the 4ghz

I hit 3.945Ghz for about 5 min and crashed.. @ 3.904Ghz it is stable for about an hour (playing CoD4) and then it crashes again.... So ATM my most stable clock is 3.855Ghz @ 1.45v (52c load) ambient @ 30c / (46c load) ambient @ 26c......

All of these tests were done with an AC Freezer Pro 64, so with a better cooler(120mm) I should get lower temps.....

With an SB750 I can get past 4Ghz.......Soon....Screenies comming soon.....

@ 3.6Ghz it doesn't even break a sweat :

well wit my titan i get 21-24 idle and 31 load. dont know my room temp but its the same as always. and if i would want to hit 4ghz i would have to put my voltage up alot right? Now is it bad to have high voltage or is it fine if the cooler can keep the cpu cool.

 

[OvrClkr]

I thought you were using the stock cooler and was thinking of getting the Core-Contact? Im confused here......

 

[huntsman]

yes but my store had titan and was number 1 on frosty tech so i decided to go for it and it was on salw. And now im using the titan cooler. Now by how much should i increase my voltage cuz at 1.35 the max i can get to is 3.6ghz running stable . I ran prime 95 blend test for 1 hour and no problems. Will run it again tomorrow for longer to make sure. And will slowly go up.

As you should already know, I reached 4Ghz!
Here's another thread where I posted this

My post for the 4Ghz is somewhere in the middle...
As for the voltage, add by .025V increments until it get's stable...

@ 3.6Ghz it doesn't even break a sweat :

I have mine oc'd to 3.8 on default voltage of 1.32 . Not sure why yours requires so much more voltage.

3.8 at default voltage? Never seen that but if you say so......

Here is a pic of my most stable overclock :

 

[dkev]

Default voltage dude.

 

[OvrClkr]

1.392 is not default voltage, if you left in on AUTO that does not mean that the voltage will stay stock. 1.300v is stock voltage / 1.392 is almost 1.4v ........

 

[videl]

Yeah, mine on default is 1.325...not sure if it's default or not but I know that it was 1.325 on auto settings...

 

[OvrClkr]

Well when you have your CPU volts on AUTO, that does not mean that it will stay constantly at 1.300/1.325v.... As they will fluctuate between those numbers @ 3.1Ghz, once you raise the CPU multiplier and North-Bridge volts the CPU volts will increase as well... That's why it is called AUTO...

 

[dkev]

I hit 4ghz stable using Overdrive. Unfortunately I can't duplicate it with the Bios.

 

[OvrClkr]

Nice!!!

What temps do you get?
