How do I overclock an AMD x2 4400+?

[4400_Overclocker]

I have never overclocked a CPU, but I want to go up from 2.2 GHZ. I have liquid cooling on my CPU and I'm not worried about overheating. How high should I go and how should I do it?

My system:

AMD x2 4400+ at 2.2 GHZ
2GB Corsair XMS Pro (1024MB each)
EVGA Nforce-4 SLI AMD 939PIN
WD Raptor 36.7GB 10,000 RPM
EVGA Geforce 7900GT 256MB PCIE
Antec 550 Watt PSU
Cooler Master Liquid Cooling Kit
Windows XP Professional (soon to be Windows Vista)

It's actually very easy. Go in to the BIOS and find the Advanced Settings tab. Then locate the HyperTransport speed. It s usually set to 200MHz and a 5 multiplier.

Leave the multiplier alone and turn the HT bus up to 220MHz That will take you to 2.4GHz. I have mne running at 210Mz with no added voltage and no heat problems with retail HSF.
For 220MHz, you may need to up the CPU voltage to about 1.37V.

Adding onto Baron's post, it also depends on how far your motherboard will go. I know my M2N-SLI Deluxe will stall at anything above 219. If you have a liquid cooling set up, you probably didn't skimp on the board. Listen to the Baron.

Well, first, I would not listen to Baron .... he achieved a whopping 10 MHz over stock system clock.... I bet it's stable....

:lol: :lol: animal!

 

[sirheck]

anyway. you should(depending on the rest of your sys,)
get a good oc. 2.4, 2.6, maybe higher?

you mentioned you have w/c so i would imagine you have good
quality mobo,ram,psu=etc.

i aswell as b.m. and i think jack has the 4400 too.
i have had mine at 2.6 for the last couple of months.
just had too reinstall everything. some windows/sys32/config error
missing file thing?
so its all stock now.

edit;actually about 6 months, i think?

But if you are really wanting to push it.... there are 4 primary things to consider. HT multiplier, system clock, memory clock and Vcore.

1. The HT multiplier is not something to leave alone, in many OC set ups the HT link/failure beyond 1000 MHz is what limits the OC. Most overclockers lower the HT multiplier to 4x before they start with the system clock/OC run.

2. Increment the system clock up, pay attention to memory speed as you work your way up to the most stable clock. Don't panic if it locks up, simply restart, go into the bios and drop the clock down 10 or 15 MHz to get stable.

3. If you want to go higher, then increase the Vcore 0.05 volts, and then step the clock up in small increments again and check for stability.

ALWAYS monitor your system temperatures while OCing, you do not want to run extra hot -- no worry though, the CPU will shut off before any damage. Without adequate cooling it is not unlikely you will run into a thermal limit very quickly.

Poof, begone. Turing up the HT bus to 210 makes my system run at 11x210MHz or for the multiplication-impaired 2310MHz.

11x200 gets you > 2400MHz.

what is the rest of your system?

Whooohoooo, overclocker extraordinaire.... the Baron speaks.

It is still only 10 MHz over system clock. Which is 200 MHz.

Also, in case you are unaware --- the system clock (which again is 200 Mhz) is what times everyting, there is only one clock for the entire MB... the HT bus is normally 5x the system clock, the CPU multiplier, in this case 11, is 11x the system clock, and so forth and so on..... you misnomer the 'HT BUS' when it is nothing more than a simple quartz crystal driven clock generator.

Well, at least you only needed two edits to get your BS straight. I have always said I dont OC much.

2310MHz from 2200MHz is abotu all I will do. If I want a faster chip I buy a new one. They actually come wth a warranty.


I believe everyone with an AMD knows that the CPU clock is a multiple of the HT clock. That's why you need .5 multipliers for the odd number clocks of Brisbane.
