If you have a look at the various steps in the guide, it will tell you what you RAM is running at for each of the steps.

The point here is that when overclocking, it's not always possible to run your memory at its rated speed, but what's important to remember is that the CPU overclock will give you better performance over all.

At certain speeds, it is possible to run your memory at 1600MHz using the different memory dividers. Using the current divider, you would need to be running the CPU at 200 BCLK to run the memory at 1600MHz though. Also keep in mind that you may also need more QPI voltage and this can lead to higher over all temps, so you need to decide if your cooling is up to the job and if you are happy to have the extra heat.

About the overclock recovery, there's a troubleshooting section at the end of the guide.

I haven't had chance to add this part of the guide yet, but it's pretty simple to figure out.

As I've mentioned in the post above this one, to run the memory at tighter timings may require some more QPI voltage, or the modules may not run at tighter timings so it's just a case of experimenting until you find a balance that you are happy with.

Try running 8-8-8-24 @ 1765MHz, if that's not stable, try 9-9-9-24 @ 1765MHz. To be honest though, memory speeds and timings over 1600MHz don't really make all that much difference to noticeable system performance.

I was about to start doing what it said on the Getting Started And Overclocking to 3360MHz (3.36GHz) guide.

After I put Ai overclock tuner - Manual... it did not let me change BCLK. I hit enter and it wont do anything. it stays at 133.

I am using a P6t deluxe v2

Strange, try a CMOS clear?

After it is on Manual it should let me change BCLK?

Also i checked the asus p6t deluxe v2 motherboard guide but did not find nothing about CMOS

Do you need to enter the BCLK value manually?

I want to enter 160 like it says on the guide. Right now it is set at 133.

Thanks for this, but it doesn't seem to work for me. I use the mobo from gigabyte: X58-UD5 with bios version F7. This guide, works: images.tweaktown.com/imagebank/Core%20i7%20920%20oc%204G%202008.12.12_(ENG).pdf. But it doesn't go in detail how to get the voltage low etc., because I know it can go lower. But this is my first over-clock, so I really don't know where to look precisely. If some one can make a step-by-step guide for gigabyte

. Or at least can help me so that these setting can help me of this guide (clunk.org.uk).

Btw I have the D0 batch.
