Yes, OCing can help your gaming experience, and keep your system capable for a bit longer.
That board does have some OC features. I'd start with updating the BIOS. http://support.asus.com/download/download.aspx?SLanguag...
BIOS updates sometimes open up new features and sometimes increase OC stabilities.
Make sure that it is the correct P5B version, they have a deluxe and wifi versions.
If you have money, invest in a aftermarket cooler. The stock cooler can only take you so far.
I searched for an easyer way to overclock my system, so I asked my favorite shoko bair (he wants me to call him so in this post -.-) and he adviced me to go onto the Asustec site and look for programs matching my demand.
So I did, and found the program: asus Al suite
The proggram has automatic overclocking functions wich didn't work at all.
The good thing about it is, that I could change The Fsb of the cpu the Voltage of the ram and the ram frequency(with the intergratad tool al booster).
Because I read pretty much about the connection between Fsb and Ram, I increased the Fsb to 330 and lowered the ram frequency to 667 (thoght it would give a Ratio of ap. 1:1).
Without complicated Bios changes for me to do, the pc restarted and is now overclocked.
Info by core temp: Core 0 and 1 46*C after a short time of testing (before 36)
I think these numbers are to low, the Bios was telling some higher number however I don't think the temperature is dangerous.
info by Cpu-z:
Core speed 2329.xx Mhz
Bus speed: 332.8
Memory: Dram Frequency 416.0 mhz
Fsb ram 4:5
command rate: 2t
didn't test the system for a long time but gave it a short stress test in a game and the performance was good.
did I do the right thing? are there any dangers (to high voltages or so)
Download your OS version. When you start Prime95, cancel the inital torture test, go to Advanced and make sure "Round off checking" is checked. This will tell Prime to stop and tell you it found an error.
Run Small FTT to test CPU. Run Blend to test overall system.
I've reckognized that my ram still were at ddr2-667
put them to the normal ddr2-800 and core Voltage increased to 1.288 Volt.
I'm very confused now because I don't see why the core increases voltage when I increse ram frequency.
and something I forgot to ask:
was it intelligent to put the ram frequency down to ddr2-667 when I first tried overclocking?
If I increase Fsb to 400, what ram frequency should I put in?
Yes, lowering your RAM to 667mhz is the smart thing to do. 60-70% of the posts about overclocking problems is because folks forget to lower they memory frequency and end up overclocking their memory to the point where it crashes.
Using speedfan to meausure temps is trickier then say something like Real Temp or Core Temp. You have to calibrate Speedfan so it doesn't give you the flame. I'm not an expert at Speedfan, I've only tried it briefly and found that Real Temp worked better for my cpu.
