Anther way to overclock your NB Frequency it to increase your FSB but this is a little more difficult as you will also have to adjust your ram dividor and NB multi not the CPU to NB multi. Are we confused yet? I don't have any CPU to NB multi adjustments in my bios and not all mobo's will have that option. So I have to overclock my NB Frequency w/my FSB.

Good Luck
I know how to overclock my HT frequency by increasing my FSB thats how we used to do it! How does the HT frequency add up like for a cpu 15 x 200 gives me 3Ghz. How much voltage can a NorthBridge take? I don't want to fry my board.
Decent I guess?

The setting to control your northbridge is called Northbridge frequency or something similar depending on your BIOS. The voltage for it is called CPU-NB. For now all you need to focus on are those two settings: Northbridge Frequency and CPU-NB. Ignore everything else.

Step 1: Increase the Northbridge Frequency multiplier by 1. For example, if it is set to 10x increase it to 11x.

Step 2: Boot into Windows and run a stress test like Prime 95 for a little while. For now 30 minutes should be good enough. If your computer crashes go into your BIOS and increase your CPU-NB voltage by 1 setting and repeat the stress test. Do this until your computer doesn't crash.

When it doesn't crash go back to step 1 and begin the process again. When you finally hit the sweet spot of 2400Mhz-2600MHz without your computer crashing you can do the final stress test to ensure that it is stable. Run Prime 95's blend test for at least 4 hours, preferably 8-12. If it passes congratulations, if it crashes increase your CPU-NB voltage by 1 setting and try again.

Don't go higher than 1.4v for your CPU-NB until you are confident in your ability to overclock the northbridge. You shouldn't need more than that anyway. 1.25v-1.3v seems to be the sweet spot for 2400MHz-2600MHz.

For now keep your HTT frequency at 200. You have a black edition processor so you don't have to make it hard for yourself. Overclock with the multipliers and worry about the HTT frequency after your overclock is stable.

My overclock is stable if you read the first post. HT frequency and the FSB are different things. Not sure if it's called FSB any more but that is the 200 you are talking about. I have it at 203 for the extra .054 Mhz and it is stable. Thank you for your guide looks very helpful. This is a picture that looks kinda like my bios (not my settings) http://images.bit-tech.net/content_i...view/bios1.jpg

Every time I chang HT link frequency my screen just stays black. I haven't tried changing the northbridge multiplier. I did raise my voltage also.

whoops forgot a T. I meant HTT frequency. I read your first post and know that you have it set to 203 but I don't see why. If you want to overclock your northbridge you should set it to 200 and use the multipliers, then increase your HTT frequency after you have a stable multiplier overclock.

I changed my HTT clock back to 200Mhz I changed my CPU NB clock ratio to x10and it changed my NB frequency to 2200mhz because I did this can I change my HT frquency to 2.2Ghz?

As you can see from the last graph you don't want to overclock your HT frequency with these processors. Most people suggest keeping it between 1800Mhz-2000Mhz.

Oh thank you very much for the info but right now my NB frequency is overclocked. Just wondering does NB frequency help get a stable overclock? I seem to be able to push my CPU to 3.8 and it doesn't crash with prime95

Can you post some pics of your BIOS? It would be easier to explain if I knew what it looked like.

For the most part higher HT NB Frequencies not only offer better stability but also help in overall cpu/ram/Total system speed. I totally forgot until a few minutes ago after reading Itseggrolltimes post but here is a link that I consider a 101 class for Ph II overclocking. You at the least will enjoy the read at most will know several things beyond what you may or may not already know about overclocking Ph II CPU's
