I've been trying to overclock my AMD 955 Quad Core processor, but I'm unsure how to get the most juice out of it.
My multiplier has been unlocked and I'm at 18x right now (3.6 ghz)
Running prime95 shoots my core temperature up to about 58 C in a few minutes. This would be all fine and dandy but:
- I'm using the coolermaster hyper 212+
- I'm using Arctic Silver 5 thermal paste (and applied well; I've reapplied my thermal paste about 3 times, each time cleaning if off the CPU and heatsink and reapplying too)
- My computer is right next to my window.
Right now my idle temperature is about 40 C.
Does anyone have any expertise or tips on how I can maybe squeeze some juice out of my processor, hopefully getting 4 ghz out of it or more?
58C under prime95 load isn't bad, you're safe to go around 90C.
So that's nothing you should worry about.
My i7 920 @4Ghz goes to 85C-90C with Prime95 and using Noctua NH-U12P SE2 cooler.
I can overclock my 980x to 4.4 Ghz on air.

People in some other forums say that 62 C is the max I should be at for this particular brand.

wow 85-90c?
get a better cooler cause those temps are really bad
62C IS the max safe temperature for a AMD processor. Intel CPU's naturally run hotter better.
I managed to get mine to 3.7GHz on stock voltage with my Corsair H50, temp's we're around 30 idle and 55 in Prime95.
I'd recommend trying to use the lowest voltage possible while keeping a stable overclock, to do this you can overclock the CPU a little bit at stock voltage until it's unstable in prime, then bump the voltage up a little bit. to like 1.390v or something. the MAX voltage you should set unless you're a overclocker looking to break records with a nice big cooler is 1.475v
this info may not be the best, but i did exactly the same thing for my first overclock. but now i'm running at stock :)

Ideally, you don't want to hit over 75C underfull load in Prime95.
Since i unlocked my CPU it doesn't give any temperature read out. :saddowns:

There's not many better coolers tbh and i don't want to change to water cooling.
And that's 1.33Ghz overclock :>

Where does the Freezer Pro 7 fit on to that graph?
I managed to get it to 3.9 ghz. It idles at 47 C and goes up to 56-57 C at load. Am I okay to push for the final .1 ghz? It's been stable for the past hour or so (just from regular tasks and some moderate stress tests)
Hey man, I talked to my mate. He said that it gets pretty unstable after 3.8GHz. I say you just tone it down and sit there.
Hmm. It's at a comfy 3.8 ghz. It's not as much as I would like it to be though.

Good to know when I buy one. Hell, you can get the box I got with it!
Damn, just noticed you rated yourself winner..

85-90c are not ideal temps but they're not 'really bad'.
I think a safe temperature would be around 75c
58c is nothing to worry about. Not even close to.
Urm you really don't want to be higher than 90c
Might wanna stick with 3.8 and call it good. Also if you're going to keep it there under moderate load you might wanna leave it on for most of the time to avoid repetitive thermal shock.
amds get hot, deal with it.

The amount of heat that a CPU puts off isn't limited to brand. There are many variables.
-Room temperature.
-Stock or third party heat sink.
-Thermal paste that is applied (stock or third party.)
-Case's airflow capabilities.
-Amount of dust in the heat sink.
-How many Watts the CPU is.
-What you set your voltages to.
-Etc...

amds generally need higher voltage for overclocks and can sustain higher voltages than intels, but you can definitely expect hardware degradation. in this case he was using a decent aftermarket cooler with AS5 in a relatively cool environment.

By the time a heavy OC actually starts degrading your CPU, it will be time for an upgrade.

that depends on a lot of factors, especially to how well your CPU is cooled. i'd give it 2 years max. also not everyone has mommy buy them a new platform every year or two (i know, this is a very strange concept.)

Hah. You are very ignorant.
With a heavy OC on a CPU you would get at least 3 years on it.
Also, I earned my own money through hard work, and paid for my computer myself. I've also bought my first two cars with my own money, and all my clothes. I bought my first car when I was 13, and none of the money I used was just handed to me for being a good kid. I actually had to sweat for it. So don't just assume that everyone has their parents pay for their computers.
Thats ignorance to the extreme.

are you done making things up? i'll be ready for a discussion when you can admit to your reliance on mommy's credit card.

I would say they're really bad. You should never exceed 80C. Never.

Whatever kid.
Would it be a good idea to try and raise my voltage a bit to try and get to that 4.0 milestone? I've got a stable 3.8 Ghz overclock at 1.4 V (default voltage).

Don't bother. It'll require too much voltage and the H212+ isn't really meant for that. It won't be as stable either.
955 will really struggle to get to 4GHz although it should get to 3.9
