Hi all im new here, and ive just built my new PC, the specs are below;

Processor:
AMD Phenom(tm) II X4 920 Processor (4 CPUs), ~2.8GHz

Memory:
3072MB RAM (DDR2 800MHz)

Hard Drive:
1 TB

Video Card:
NVIDIA GeForce 9800 GT

Monitor:
26 Inch TFT Monitor

Sound Card:
Speakers (SoundMAX Integrated Digital HD Audio)

Keyboard:
USB Root Hub

Mouse:
USB Root Hub

Mouse Surface:
My Bed, Lolz

Operating System:
Windows 7 Ultimate 32-bit (6.1, Build 7100) (7100.winmain_win7rc.090421-1700)

Motherboard:
Crosshair II

Computer Case:
Antec Nine Hundred

I was wondering if the Antec 900 had enough cooling for a minor overclock, without any added fans apart from the ones that come with the case, and the components already?

Also i was wondering if with just the stock fans for cooling, if i could potentially get 4.0GHz out of my CPU?

Im gonna follow that neat little beginners guide on overclocking to see what that brings, thanx for your help in advance :)
 
I'm not an AMD expert but I can definitely answer two questions for you :D.


The Antec 900 pushes a lot of air, so you will have no problems getting hot air out of the case.

However, the stock cooler is not enough for 4Ghz, I'll leave an AMD specialist to recommend a cooler.
 
The 900 has great airflow, what you need is an aftermarket CPU cooler though, if youre not too bothered about noise, the titan fenrir is excellent
I wouldnt worry too much about RAM as it has little real world effect, in fact whilst OCing your CPU its best to UC your RAM, that way you know youre not going to run into difficulties
the GPU is totally separate
 
AMD overclocking is a little difference to Intel, a lot of the performance is also based on the HT/NB speed and it is often worth sacrificing 100 - 200mhz CPU speed for a similar boost in HT/NB speed.

I have found when overclocking a few 955BE that the most difficult part of any AMD overclock is ensuring the memory and NB are stable.. you don't have to overclock these and just do the normal multi/fsb increase but you wont gain 100% of the benefit doing it that way..

I would suggest you run your overclock in three steps this is going to take a while, probably a couple of weeks but it will get you the best and most stable overclock.

I suggest you design yourself a spreadsheet of speeds / voltages as this will make reference a lot easier.

First stage is to clock your RAM or get you machine stable with the RAM frequency / timings that you want, quickest way I have found to do this is by running 5 loops of IBT a 4gb memory (or the most you have).

Stage two is to clock you NB/HT sweet spot is around 2.4 - 2.6ghz, stability is gained from NB voltage and NB-CPU voltage... keep an eye on NB temps as NB-CPU voltage especially will send those through the roof! I try to keep my NB below 55/60c I find above that I lose stability... again stability tested via IBT 5 passes at 4gb

stage three is CPU overclocking.. this is done through FSB and Multi.. be aware FSB will also increase your memory and NB/HT and therefore refer back to stage 1 & 2 for appropriate settings..
 
I kinda understand all that you said dude,but is there like a more in depth guide on how to carry out them three steps? If I only wanted an over to say 3.4ghz could I not use the beginners guide,or is your way better for an Amd setup?
