Hard time OC'ing on a 955?

See the thing is that i have a Phenom II x4 955 and i currently run it at 3.81 Ghz and it idles at 56 degrees Celsius. when im playing a game like MW2 it gets up to around 63 degrees Celsius. And under Prime 95.......well it goes for two minutes and then it crashes...:( 

but im okay with this "semi-unstable" OC since prime 95 and stress programs seem to be the only thing that can tear this clock speed up into little pieces...lol

but what im wondering is that to get to 3.81 Ghz for me, i would have to put it at 1.6V for my cpu, the maximum the BIOS would let me without giving me a warning.....any help?

I have a 630W power supply and my CPU cooler is the Zalman CNPS 9700

So your considered about the heat? Or the voltage....I have a hard time trying to get the point your making

im just concerned about the voltage to overclock ratio

I am running at 3.6 and using 1.350v so It seems high to me and ya temps seem warm to me do you self a favor and get your self a Coolermaster Hyper 212 it will blow the CNPS9700 out of the water and it's cheaper

i was actually thinking about the TRUE or the V10 or something by cooler master, but i dont know if it will fit in the Aztec case by Raidmax w/o taking out a fan

the main reason that i chose the 9700 is because i KNOW for sure that it would fit in my case

oh yea will the V8 fit in my case also?

First of all, if you are getting over 60c at 3.8Ghz and you have re-seated and re-pasted correctly then that normally means that it is time to upgrade your cooler...You do not use 1.6v regardless.... On AIR the 955 will max out at 1.58/1.59v due to its heat threshold unless it is snowing in your room ;) 

Get a REAL cooler, something like the 212+/dark knight/CCF etc.... No need to spend 100.00 on a TRUE unless you absoulutely need it....

I get 27c idle / 43c LOAD at 3.8Ghz w/ Titan Fenir LE :

Idle @ 56C? That's hot. Clearly, that Zalman cooler fails to do its job.

Plus, you don't need to jack up to 1.6v just to get to 3.8ghz. Get a better cooler and you might be able to do it.

oh yea, i lowered the voltage down to around 1.5 volts and now the idle is 45 degrees and the load is around 56

You should not have any issues, I have an Antec 300 and the V8 fits just fine considering the 300 is among the smallest mid-towers.... just make sure you do not have a fan on the side panel ;) 
February 6, 2010 11:13:42 PM

well, that could be arranged.....as soon as i take out the side fan that i "conveniently" have.

I took a look at the fan and it's attatched to the plexiglass in a funny way....there are no screws or anything....is it really necessary to take it out?

how much taller is the V8 than the 9700?

it looks like i've got around half an inch to work with

First install and check clearance. if it interferes remove the fan...

The V8 should be a few mm's taller ;) 
February 6, 2010 11:25:08 PM

one more thing: does the V8 have an AM3 bracket? or does AM2+ work as well...........and it may be stupid for me to ask this but do i need to take out my motherboard for installing the backplate for it.....if it even has one?

Yea the V8 comes with the AM3 bracket, if your mobo tray does not have a hole for the bracket then YES you will have to remove the board...
February 7, 2010 1:29:53 AM

yea, meaning that i first have to remove the standard clip-on thingy?

Probably raising the N/B voltage will allow lower vcore, but I'm curious as to how you reached 1.6v in the first place, basically the idea is to creep up the vcore until the voltage is sufficient to handle a higher multiplier, you CPU is a BE? Unlocked multiplier Right?
February 7, 2010 7:08:51 PM

yea...i'm afraid i'm gonna screw up something.....i know that when i set the "ratio" as they called it for the CPU/NB at 3200 Mhz, then i would have to clear the CMOS and it wont work. What should be the standard NB voltage anyway? and what's the Maximun NB voltage? i don't really know how to clock a multiplier either

Yes, its just 4 screws, you remove it, install the new bracket and your done... Then when it is time to install the cooler, paste the CPU slap the cooler on the CPU (patiently), screw the downplate little by little, one side at a time (1/2 twist) and once it starts to tighten up you are done...

also i don't know what should be most of the settings in my BIOS. i know that advanced clock calibration doesn't work no matter what. Is it just me, or do intel's overclock better and easier?
