Help me with my overclock please :)

My system specs are in my signature, although the 4.2 part is no longer true.

I got my bundle from OcUK at 4.2 about a year ago, since putting in my new GPU I had issues with my overclock and now it is back at stock speed. Now I want to manually overclock my i7 but I don't have a clue about overclocking my CPU.

Could someone tell me what I need to change in bios please or a good document about this or someone with a similar set up can you post pictures of your values please?

Many thanks

Ok I found a guide over http://www.clunk.org.uk/forums/overclocking/22106-core-i7-overclocking-guide-beginners.html

one thing which confused me was the ram part.

Next, the DRAM Timings.

You only need to change the top Four settings, these are your main memory timings and it is important that you set these values to whatever it says on the label on the heat spreaders of your modules - The DRAM voltage is equally as important too, see further down for that:

But on the screen shot it says 7-7-7 on the ram but in BIOS he puts 8-8-8-24?

I'm just worried about damaging hardware -.-

And also he put

DRAM Frequency - DDR3 - 1282MHz - If you use memory that is slower than 1600MHz, you can use the next lowest setting here, however, if you use faster memory, such as 1866MHz or even 2000MHz, please stick with this setting for now.

If I'm using 1600mhz why don't I put it to 1600mhz in BIOS why use a lower setting?

Looser timings and slower memory let you push your cpu further. If you try and overclock both at the same time and get an error, it's difficult to know which caused it. Slacking off the memory allows you to find a stable cpu clock before tampering with memory

Also overclocking the CPU via the baseclock will overclock the RAM (and everything else on the motherboard) as well. You have to lower the memory divider before you start in order to avoid the RAM being the limiting factor in your overclock.

I "don't" think messing around with the timings will destroy your hardware. Voltages/too much current/high temps will.

I think you'll end up doing if you have invalid timings is either BSOD, random program crashes etc.

Thank you very much
