Need help overclocking Phenom X4 955 BE!

Schytheron · May 13, 2013

I have a Phenom X4 955 BE and i just sucessfully overclocked it to 3,6 ghz on stock cooler (its running 55-56 celsius on load) but my voltage bumped itself up to 1.45. Thats probobly a little high. So how much should i lower voltage and how much should i increase multiplier. I want to overclock it to 3,8 ghz but its not gonna work on this voltage. I will probobly get to much heat.

Buy an aftermarket cooler to continue past this point, I'm extremely surprised you achieved such a high overclock with such low temps @ 1.45V. You seem to have a pretty sweet chip.
I recommend buying a cooler master tx-4 leaving the voltage as is and then up the frequency from there.
I would bet that this chip hits 4Ghz on that voltage no problem.

55-56C is actually not that high; 70C is where things starting getting really hairy. You can certainly up the clock and voltage a bit.

Though running 24/7 at 70C isnt an ideal situation. An aftermarket cooler is ideal, or atleast, try tweaking it. Maybe you can get 3.7 on that voltage or 3.8 if you try; maybe you can disable a core if you don't need it depending on your uses for reduced heat; there are lots of possible solutions.

Phenom X4 955 BE gets damaged past the 62c point...

Im really confused about this voltage thing. I have my voltage set to offset at 1.4 yet it runs 1.45 while idle and 1.4 at load... that doesnt seem to make any sense and when i set my voltage to manual my PC start freaking out.

Btw when i was running stability test today the temps were around 58-59c. Now im afraid to bump up frequency. What voltage works for most people at 3,8 ghz? I want to lower voltage first but i dont know by how much....

Put a negative offset on it. I run stable 3.8 @1.385 at a max temp of 48C

Schytheron · May 13, 2013

rex4235 :

How do i do that and what does a negative offset do?

rex4235 · May 13, 2013

Offsets do not equal the exact voltage that they appear to be first off. So setting an offset of +.25 will not increase your vcore to 0.25 volts. Secondly, all you have to do is (as it was in my case anyway) instead of using the "+" to increase the offset, use "-" to go below 0.0 and its trial and error from there. It will basically lower your idle vcore and lower the max voltage achieved under load.

How come my voltage is being the other way around? I get 1.45 idle and 1.4 at load... doesnt make any sense.
If i set it at 1.4 manual then my PC starts freaking out... my CPU chip is fucking retarded -_-

rex4235 · May 13, 2013

Try turning off Cool'n'Quiet -- and its not going to be your CPU thats "retarded" its your MB/ BIOS; your CPU only receives what the MB gives it

rex4235 :

I have turned of cool n quiet a long time ago...
Btw in BIOS it said that my voltage was 1.450 so i did as you said and i put a negative offset and i tried to bring it down to 1.385. soo as negative offset i set 0.065 and when i restarted my PC and opened CPU-Z it said my voltage was 1.344.... NOW HOW THE FUCK IS 1.450 - 0.065 = 1.344?? My pc cant do simple math

rex4235 · May 13, 2013

Listen, as I said before, when dealing with offsets the value isnt equal to the voltage. An offset of -.25 DOES NOT EQUAL .25 volts. Its a ratio, you have to use trial and error to reach the target voltage.

Schytheron · May 13, 2013

rex4235 :

Its a ratio? So .25 = 25% or am I just being retarded right now?

Btw I cant seem to figure out why my Voltage is doing the complete opposite of what it is supposed to do. Running 1.45 at idle and 1.4 on load. It doesnt make any sense why my PC cant handle manual voltage but offset is fine.... WTF....

Schytheron · May 13, 2013

NVM i have reset bios completely and will try to do this from the beggining... the proper way. Anyways im running a High performance energy profile in windows and while im running it Cool and quiet is greyed out in BIOS. The greyed out zone says [ENABLED] but im guessing its disabled since im running a high performance profile and its greyed out... right?

Schytheron · May 13, 2013

My overclocking progress is going way better. The reason behind the voltage dropping at load was because load line calibration was disabled. I sucessfully ran 3,6 Ghz at 1,32v but 1,32v is below stock volt and i thought i might damage something (because sucessfully overclocking under stock voltage isnt normal i assume) so i upped it to 1,35v. Its getting pretty late now so i will continue on my overclocking tomorrow... cya later

rex4235 · May 13, 2013

Overclocking at stock voltage isnt abnormal... I only needed to bump mine up to get past 3.6

And no, you cant hurt anything undervolting. The only issue would be stability -- the PC would just "restart" randomly. Your goal IS to get the OC you want at the lowest Vcore while staying stable

Schytheron · May 14, 2013

rex4235 :

But i didnt overclock to 3,6 ghz AT stock voltage... i did it UNDER stock voltage and it worked... that is pretty unnormal

rex4235 · May 14, 2013

No its not -- not all chips run at the same stock voltage, some are higher at stock then the actually need to be. The higher the vcore, the higher the temp but it takes away any stability issues that may occur
