Overclocking 4400+ Brisbane

post #1 of 25
Thread Starter 
First of all, this is my first time overclocking and i do have a general idea of what i am doing. I am not looking to overclock very much but i want to get it very stable. My mobo does not allow me to change my multiplier so i am going on bus speed alone. So far i have overclocked my cpu to 2.4 GHz by increasing the bus by 10 MHz and the HT went up to 1050. My ram freq went up to 840 MHz due to this and it is at 1.95v, 5-5-5-15 timings. I would like to know what i have to do in order to bring my system to a 1:1 ratio and just speed it up overall because i am clueless on the specifics.

Thanks

Well i just read that but i have some problems lol. My mobo doesnt allow me to change my cpu multiplier, change memory freq, or the cpu voltage. Since i can basically only raise my fsb basically, id like to know how much this ram's http://www.newegg.com/Product/Produc...82E16820231098 frequency can go up to and the general area of the maximum HT i can go up to. Thanks

hi, try to read through this thread. it's hard for others to help you w/o knowing what kind of motherboard you're using.

I'm assuming, from the information you gave use, your overclock is most likely barely stable as it is (just an assumption though).

Try googling Orthos and Prime95. They are two very good stability testing programs. I'd keep your overclock where it is for the moment, and run one of those two programs overnight.

Do you know what kind of temperatures you're getting? If not, install Everest Home Edition, or Speedfan. It's quite possible your motherboard also doesn't have sensors, and you won't be able to check. Could you link me where you bought your motherboard, just as verification?

I assume your temps are alright, AMD usually has high quality stock heatsinks.

You also want to get CPU-Z. That's a fantastic program for looking at speeds, etc. Since you can't change the multiplier, your RAM is going to be increasing along with the FSB.

For the moment, you are at a 1:2 ratio. This means that your ram, 400MHz effective, (800MHz total) is increasing by double the amount you increase the FSB/Reference clock by. Since you increased the Reference clock 10MHz, multiply that by two, and you see you have increased your RAM by 20MHz each stick, giving you an 840MHz total.

Your HT leads me to believe that you have a 5x Multiplier, which is usually not great for overclocking. 210x5=1050.

I would not recommend overclocking on that board if you have only one option you can change. Are you positive there's not advanced settings configuration that allows you to change everything?

Jasoncho, to change your CPU Multiplier via BIOS, go into "Performance Booster". I believe the option that you need to look for is called "NPT Fid control". You can also change the memory frequency by going to DRAM Configuration->Memory Clock value or Limit.

All of this is discussed in your manual starting on page 31.

Good luck

Paper, AM2 processors overclock quite well with HT speeds between 1200-1400mhz. This may be something he might want to try

If its any help, im at 228 FSB right now, 2.61 ghz, and the only reason im not going higher is because ive reached the max on my mobo. I think this cpu is capable of a lot more if i had a better mobo. Temps are idle at like 32 right now, 26 with all my fans on.

Welcome to OCN! Regarding your RAM--I'm running that exact RAM in my sig rig. I can run it at up to about 950MHz with 5-5-5-15 timings on 2.1v--seems that above that frequency, despite timings and voltage used, it doesn't want to run. So you have a little bit of headroom available to you if you can increase the voltage going to your RAM.

Regarding maximum HT--that tends to vary from mobo to mobo--and on AM2 boards, it seems like most are tolerant up to about 1200MHz, give or take (from what I've read).

I was wondering what NPT Fid control was lol. Ill look for the mem clock again because i never saw it when i looked but my mobo never came with a manual. It just came with a color sheet for showing what is what on the mobo. Ive run prime95 for 12 hours and its stable at the settings i have now as well.

Edit// Does anyone here have any idea on how to change the cpu voltage on the mobo i have?
