Need helping overclocking my i7 920

[Shallowmist]

Ok so i decided to push my i7 abit cause i am getting a new pc in a few months and now i am not afraid to blow this one up. Any way

I7 920 D0 with Corsair H55 as cooling in the Haf 922

Motherboard is Gigabyte UD5 rev 1

RAM is OCZ gold 1600MHZ certified + Dominator DDR3 1600MHZ certified i know different brands but what are you gonna do they removed the OCZ by the time i wanted to buy another stack it's 12GB in total

So any way i have a Vcore of 1.25 right now
the QPI VTT are set on 1.180 i believe
CPU PLL is 1.84
With these settings it runs without problems
I am pretty sure i can reduce some of those to something first time i am overclocking so help me not blow this up.
QPI link is at 2800
RAM is running at 1500 BTW i
Runing at 3.4 with turbo mode enabled.

on
1.25 V core
QPI/VTT at 1.34
CPU PLL at 1.88V


and Dram at 1.62

I fail misirable to reach 3.8

i just sold hardware on ebay way older than that and got a decent amount of cash. you really shouldn't blow it up, not only because of the money you can get, but because there are a lot of people who would love to have that setup. the first thing you should do is remove the memory that doesn't match, because it creates a variable which is hard to make an account for.

Thanks that's a great remark butwould you still help with overclocking it ?

Look i don't "WANT" to blow it up i just want to overclock it abit i am not even aiming for 4.2 K which i know these cores reach because 2 of my friends have them and both have em on 4.2 for the last 2 years. I just wanna hit about 3.6K i know it's completely doable i just don't know exactly the correct voltages i need so i am asking for help, as opposed to blowing it up by randomly in puting voltage.

You're confusing qpi link speed with uncore frequency I'm guess. A couple things to keep in mind.

1)Uncore frequency should be double that of ram frequency. So you set uncore to 3200 if your ram is running at 1600, or 1500 and 3000 for your current settings.

2)you want to set the lowest qpi link speed if it isn't already.

3)Set ram voltage and timings to as close to factory specs as possible. You have 1.62, not should what ram needs that voltage. Seems more likely you need 1.65 if it's older 1600mhz ram

4)At 1.25v on the cpu with a DO stepping, your good for 3.8 all day long if not higher. Other settings are likely the culprit and you can probably lower it, but you'll have to test.

5)I went through this guide and board to help me a little http://www.overclock.net/t/538439/guide-to-overclocking-the-core-i7-920-or-930-to-4-0ghz

Thanks will try that next.
