There's an update to this coming soon. Should be out next week. We'll let you know. Great improvements to an already quality guide.

Thanks for the feedback...glad it helped!Thanks, Very nice guide, , I spent the afternoon playing around with this. It works very well on the P55 board. Max bclk on my P55A UD6 without going crazy on the VTT was 220. I did short LinX runs to test for stability, 10 passes to save time.

Thant was the idea Please post in the forums if you have questions that the guide does not address. We're here to help...great job so far, keep it upAwesome guide mia...
I was able to get 4Ghz (8hrs stable) without ht, and only 3.8ghz with ht only somewhat stable prior to this. Using this guide as a reference I'm now working towards 4.3Ghz HT stable. Breaking it up into sections like that is the key, you cant change a ton of settings at once because then you dont know why its failing.
Breaking it into sections allows for much easier trouble shooting. Keep up the good work man
Great feedback! Thanks!First of all I'd like to thank Miahallen for putting together this extensive guide, I think it's a step in the right direction for a lot of people like me who have absolutely 0 experience with overclocking.
One piece of feedback that I wanted to leave is that as an owner of an i5-750 running on a GIGABYTE GA-P55M-UD2 I found some of the variables mentioned in the guide to be missing or new ones to be present. If you're completely green like I am, it's be very helpful to know how those additional (or missing) variables relate to what's in the guide. Here's a couple of points that were unclear to me:
- The "Bclock voltages" section talk about an IOH voltage. On my p55 gigabyte there's no such thing, instead I have a CPU Vcore, a Dynamic VCore (DVID) and a QPI/VTT Voltage. The Vcore is mentioned at the end of the guide in step 3. Given that IOH appears not to exist in P55, do I just ignore the suggestion to raise it to 1.3-1.35?
- In the same section, and in the rest of the guide, you measure tweaks to the VTT in terms of +0.xV (where x is a number). What does that actually mean? Are you saying we should take the default value of the BIOS and increase that by +0.xV? I guess the confusing part is that in my menu there's the DVID variable which actually does have + and - 0.xV settings, so to me it's not clear whether you're asking to keep the VTT default and tweak the DVID, or if I should ignore the DVID and only increase the VTT.
Thanks!
A huge shout-out to Senior Member "Brolloks" for his invaluable input on this update....I couldn't have done it without you man!
Innacurate:
Quad core i5 CPUs (Lynnfield) are identical to the low end i7 CPUs, the only exception being the lack of Intel® Hyper-Threading Technology. All i5 CPUs work only in LGA1156 based motherboards.
I5 750 being the only quad core out right now, you can add to that blanket statement "and vt-d, which allows virtual machines direct access to the hardware."
See the following:

It's basically the stuff required for using real 3D hardware in VM's. I say give it 2 more years and somebody will come up with some type of shell operating system that lats us run Linux and Windows in parallel. A super lightweight and flexible hyper-visor...
With appropriate linkage of course.Quad core i5 CPUs (Lynnfield) are identical to the low end i7 CPUs, the only exceptions being their lack of Intel® Hyper-Threading Technology, Intel® Virtualization Technology for Directed I/O (Intel® VT-d) and Intel® Trusted Execution Technology (Intel® TXT).

I'd love to be able to utilize all my hardware natively and be able to swap between os's at will. A man can dream, right?
