Well presented with simple yet explicite detail.
I have "pushed" this to a few people to read before they start on Overclocking .
As has beeen said before Great job!

Sticky!!! I've been wondering if anyone was going to do us the favor of writing a guide like this. Good timing too because I just switched back to Intel and this is my first c2d.
I really appreciate your hard work!

Very well done. Thorough and well written. Covers most of what you need to know and then some. Good links within it, too.

First off, Great thread man. I was away for a few days and noticed this sticky, HIGH FIVE!

I do have a question that was something you touched on but was brief.

I have been trying to find out how you can determin the output memory ratio value. You listed the following but say im not running 333MHz and I want to see what frequency will come out for each ratio? I know I cann use my motherboard to determin this but how can I do it with a calculator?

FSB : DRAM
1:1 = 333 MHz : 667 MHz
4:5 = 333 MHz : 883 MHz
2:3 = 333 MHz : 1,000 MHz
3:5 = 333 MHz : 1,111 MHz
1:2 = 333 MHz : 1,333 MHz

graysky,

I have a question on lapping a heatsink. (The thread on your Ultra-120eX is closed, so I'll post here.)
I have a Tuniq Tower. Its so top heavy that I don't dare try to lap the base by moving the entire unit. I assume you smoothed out the base on your Ultra-120 by setting it upside-down and moving the glass and sandpaper. Could you clarify?

Thank you, thank you for writing this very clear and concise guide! I've got an Intel QX6850 and you answered all of my questions, raised some new questions and then answered those!

I'll definitely pass this guide on to others I know who are just starting to think about OCing their computers.

FSB : DRAM
1:1 = 333 MHz : 667 MHz
4:5 = 333 MHz : 883 MHz
2:3 = 333 MHz : 1,000 MHz
3:5 = 333 MHz : 1,111 MHz
1:2 = 333 MHz : 1,333 MHz
You can do it with a calculator or spreadsheet using the ratios.

1:1 = 1/1 = 1.0
4:5 = 4/5 = 0.8
2:3 = 2/3 = 0.66667
3:5 - 3/5 = 0.6
1:2 = 1/2 = 0.5

To get your base frequency "FSB" in my table for the standard 1,066 MHz quad pumped, you divide that by 4 to get 266 MHz. To get your RAM's frequency "DRAM" in my table, you double that since we're talking DDR2 here to arrive at 533 MHz. The rest is just using the multipliers. Thus:

DRAM = (2 x FSB) / ratio

FSB : DRAM
1:1 = 266 MHz : 533 MHz
4:5 = 266 MHz : 667 MHz
2:3 = 266 MHz : 800 MHz
3:5 = 266 MHz : 889 MHz
1:2 = 266 MHz : 1,067 MHz

If you wanna start at 400 they become:

FSB : DRAM
1:1 = 400 MHz : 800 MHz
4:5 = 400 MHz : 1,000 MHz
2:3 = 400 MHz : 1,200 MHz
3:5 = 400 MHz : 1,333 MHz
1:2 = 400 MHz : 1,600 MHz

Get it?

No, I actually did it by moving the whole thing on the paper as described. You have to take you time to avoid it hopping around. You can read a full blown article based on my posts here and elsewhere at techarp at this url that might clear things up for you.

The TT should be no different than the U-120 Ex as they are both pretty oversized, massive HS's.

Just clarification

Ok, which would be better for performance:

To clock the CPU at presumably 333, PCI-E to be kept at 100.

Or to leave the CPU at 266 and to increase the PCI-E more than 100?

Just FYI, my video is 8800 GTS 640 (g80).

PCIe has little to do with system performance. Only stability.

Just put the PCIe to 110Mhz and start overclocking!

The settings should work independent to O/S. I can't comment on Vista beyond the usual knock against m$ for releasing it too early. Maybe it'll be fixed by sp2
