How to: Overclock your AMD Phenom II 955

[doggysoftbg]

Dude I'm sorry but you don't have to bump the voltage to go 3.6GHz.

I got as far as 3.9GHz (and 4.2 un) STABLE with NO Voltage increase... ;)

[LRoyz]

Dude I just got this CPU, but why not up the FSB, isn't that like a better performance increase compared to upping the multiplier?

[letalmike]

my 955 makes 3,8 ghz with stock voltage(1,4v) and 4 ghz with 1,45v fully stable in benchmarks and games. i have a gigabyte 890fxa-ud5 mobo...

[Damizano]

I OC my 955 to 3.6 ghz on stock voltage runs stable never crashes., 3.7 crashed only after 4+ hours of Battle Field 3 on max settings. Download AMD OverDrive. Install open go to Clock/Voltage, Go down to Clock make sure select all cores is checked. Increase to 18x apply and boom. You won't fry your chip with multipliers. Your computer will only restart. as well once you reboot it'll go back to stock. 60 Cels is ideal. But, I run mine at 67 C happily. Above 70 is bad news.

[fatgonzo]

Seems the stock cooler can handle 3.6 just fine. It's noisy as hell though. I got the 955BE around the time it came out and it's been awesome value for the money. Now I ran into this video and decided to give it a go, so thanks. =)

[ilikejumpstyle]

i have x2 and originally the motherboard set the cpu voltage to 1.4 v... any ideas? when i lower, bf3 starts crashing...

[Damizano]

@ilikejumpstyle I OC my 955 to 3.6 ghz on stock voltage Download AMD OverDrive. Install go to Clock/Voltage, Go down to Clock make sure select all cores is checked. Increase to 18x apply. Safe and stable. 3.7 crashes after a few hours. 18.5x...80+ Cels will slowly kill your chip. 60's are fine CPUID HWmonitor best for heat.. GoodLuck!

[DACRAPA1]

dude...3.2 to 3.6?....you can do that shit with the stock cooler....amd wants you to..

[Blaze11000]

how i know if the over clocking worked??

[Damizano]

@Blaze11000 I OC my 955 to 3.6 ghz on stock voltage Download AMD OverDrive. Install go to Clock/Voltage, Go down to Clock make sure select all cores is checked. Increase to 18x apply. Safe and stable. 3.7 crashes after a few hours. 18.5x...80+ Cels will slowly kill your chip. 60's are fine CPUID HWmonitor best for heat.. GoodLuck! CPU-Z is a program that tells you your current clocks on all hardware. Don't use your Motherboard for OC its dangerous. As well as upping volts.

[invisible0tom]

its super easy in BIOS, all I had to do was increase the multiplier and the voltage to 1.5 and I had a stable 4Ghz cpu in less time than it took to install the cpu cooler.

which by the was is a Be Quiet! dark rock which keeps it at a cool 27-30C idle and 44-46C under 100% load, while still being super quiet, I can't hear the cpu cooler over the case fans even under 100% load at 4GHz!

if my max 100% load temp is 50C I have a lot of OCing headroom!

[TheMatias2]

Ty for the tut, helped me alot.

I Oc'ed my 955 be to 3.6, I got Mugen 2 rev b.

and I notice that before and after OCing the temp didnt change... Is that normal?

[XCARxPILExUPX]

@TheMatias2 The Mugen 2 is a pretty good CPU cooler. So yes.

[HemiPhenom955]

Just my .02

I bought the 955BE a little more than a year ago,, i used the Stock Cooler for a week,, to break in the CPU,, then i laid the wood to it,, i set the Multiplyer to 20,, the CPU Voltage to 1.55. and got rid of the Stock cooler for a much better one and have been Running VERY stable at 4 GHZ for a bit over a year now.

All settings done in bios. Check my vids out.

[mast3rmgl]

@HemiPhenom955 Nice case lol

[DeadlyPancakes]

are all four cores unlocked when you get the CPU? if not how do you do that?

[TheRoby117]

Why do i need change the CPU voltage?

And what means the CPU voltage? (Im a beginner)

[jeenormus]

all you would have to do is to change the multiplier to x18 thats it

[AToastedPopTart]

@XCARxPILExUPX soooo i shouldn't use the normal fan that most computers come with to overclock my 955?

[XCARxPILExUPX]

@AToastedPopTart Yes

[kushiee1]

i bought a new cooler to :D

[FELIX0123]

max voltage for amd 955 is 1.55v, and it's not called a free clock ratio... lol all 955 or B.E(black edtion) or should i say all B.E CPU has unlocked multiplier...

[idan124]

man if the system are not boot after overclock you dont need to tuach the batary u can use the clr option to reset the bios systen and sorry about my eng ....:)

[kushiee1]

i have a phenom x2 955 and i overclocked it to 3.8 ghz without changing the volt

in full load it runs at 55C and i'm using the stock cooler :D

[Emecepola]

@kushiee1 lucky as

[mangymetal]

@kushiee1

if this it's true, ur a lucky bastard.

BTW full load = linX or playing games?

[kushiee1]

@mangymetal i dont know if i already replied or not bc youtube is weird... but i test it with prime 95 and now i have oced it to 4.3 ghz and it runs at 64 C :D

[mangymetal]

@kushiee1

check it out in linx, it will explode xDD

[kushiee1]

@mangymetal i dont see why it would explode since it cant go over 100% load right ?:D prime makes all of the cores go to 100%

[auazn]

im able to get 3.6 mhz with stock voltage. idle:39C. full load 48C.

the fan im using is CL 212+. :)

[tibian8989]

HOLY SHIT !!! I crashed my processor !!! :(

[gambaownsus]

What do you mean in small step, you mean by increasing the voltage carefully right?

Well, I have on CPU-Z 1.344 volt. So basically what Ill need to do is change the clock ratio to x18 and then add how much on the cpu voltage. I am not sure how much should I add to my current voltage. What do you suggest me. ( I am a big newbie ) Thanks.

[gambaownsus]

So after that i OVERCLOCK , should I run a stress run ? if yes, with what program and what is the right temp, or a stable overclock? thanks

[XCARxPILExUPX]

@gambaownsus Try "Prime95". Just choose "In place large FFTs" after running prime95. You can download it for free. Your CPU (955) shouldn't reacht 65°. Best Temp ist between 50 - 60° in load. OC your CPU in small steps when you are unsure.

[Littlestokesey]

@XCARxPILExUPX Why is my cpu on idle 53c and on my old one it was 36c when i game it goes to 65c theres no dust i only bought it yesterday my case has good airflow

[Tyris1013]

@XCARxPILExUPX You're kidding me? My idle temp while overclocked is 43-45 and max 55 on load, but underclocked is about 35-40

And with max temp hit 62, I'm freaking out :s

My clock is 3.8GHz atm with NB 2.6 (1.4 Vcore and 0.5 NB core)

And I use Zalman CNPS7500 CU LED CPU Cooler :( is it a bad cooler?

[gambaownsus]

1.475 isnt too much for it? Can I lower it?

[XCARxPILExUPX]

@gambaownsus You can try it. Every CPU is different.

[pty1717]

I'm new to overclocking. If I just increase the multiplier and voltage some will I have to adjust all the other stuff if I just want to overclock my CPU and not my RAM or anything else?

[crimson177]

i got my 955 to 3.7ghz on stock voltage

[crimson177]

i prefer gigabyte bios 

[FELIX0123]

im pretty sure this board to get uip to 4.0ghz with 1.40 voltage

[MattiDaimen]

so can i do this in amd overdrive? cuz then you don't need to restart your computer:) please answer

[XCARxPILExUPX]

@MattiDaimen Yes you can do this in amd overdrive too. But I don't use it because it let's my computer crash.

[ki55eLL]

This 'Auto clock' is called Cool'n Quiet by the way :)

[zakoe07]

I should have 3.2GHz but I have 800MHz. Why the fuck is that?

[XCARxPILExUPX]

@zakoe07 Then you have auto clock on. This underclocks your Frequenz when you don't need power, but overclocks to 3,4ghz when you play something or video rendering.

[zakoe07]

@XCARxPILExUPX How do I put auto-clock off?

[XCARxPILExUPX]

@zakoe07 You can set it in your BIOS. Just go to CPU Clock Ratio and set it from "auto" to x16 for 3,2Ghz

[zakoe07]

@XCARxPILExUPX But one problem: I can't do that. The screen has no signal. I sthat because of my graphic card?

[67CopperHead]

sorry to say but every one dont get volt 100% right that why there is prime 95 to get it right pluse the only time you will fry your CPu on volt is if it goes over 1.55v on the Phenom II x4

[projundertax]

@67CopperHead nigga u stupid :D

[67CopperHead]

you over volted if i am coreect yoru volt is 1.35 pluse 0.125 = 1.55V wich is over volte with is very bad

[XCARxPILExUPX]

@67CopperHead Lol... 1.35V + 0.125V = 1.475. Are you bad at math?

[killer4uman]

@XCARxPILExUPX yep, he is, and spelling since he spelled "plus" wrong, he also misspelled correct, volt, and your, hes just dumb

[SterbendDSBM]

@67CopperHead FAIL xD

[67CopperHead]

@SterbendDSBM Nope no Fail becuse im a better overclocker then u kid's i overclocked my Phenom II x4 955 at 3.7GHz with only 1.40V

[SterbendDSBM]

@67CopperHead hey retarded, i said you fail at math hahahah, and its obvious you do !

And 1.55 is not overvolting, 1,55 is just the maximum limit for these CPU.

I overclocked it to 4GHZ with a low voltage but i didnt come here to praise myself.... fuck you, end of disscussion!

[zfkdaniel]

hello, i can overclock my amd sempron from 1.6 ghz to 1.9 ghz?

[TOBIjenster]

danke :)

[bustsomewax]

Great to the point video. I'm currently OC'ing my 955 to 3.8 and staying around 38c(idle)-56c (full load).

[MacuiareNipples]

@bustsomewax Hey what cooler are you using?

[bustsomewax]

@MacuiareNipples

Asetek low cost liquid cooling.

[MacuiareNipples]

@bustsomewax Thank you very much

[xXDavePCTutorialXx]

@bustsomewax got the same temp @ 3. Ghz by using the blue orb cooler .. :)
