Core i7/X58 Overclocking Thread

[jasonelmore]

I did 4080 MHz with the 920 and Corsair Dominators shown 6 posts above, that was with 1.5V though which may be a bit uncomfortable for most of you.

your were using a 965 man not a 920..

Retail i7 920
Gigabyte EX58-UD5 - F3 bios
Fusion v1 - mounted with only two angled bolts :-D
Corsair 3x1GB kit 1600c9

Vcore - 1.3125 Bios - 1.264 under load - loadline calibration enabled
Qpi/vtt - 1.28v
Vdimm - 1.6v
All other voltages one step above default.

just bought today a 965 @ 3835A538.....
waiting for mem and will start playing..

[dark2099]

Are 3 sticks of RAM needed for a setup to work, I am waiting on my other set of G.Skills to come in the mail today hopefully. So when I pick up my setup later I will only have a 2x1GB set to work with.

[giorgos th.]

you can also work dual channel..

What's the setting called in the P6T bios that turns off TDP Protection?

[ap4lifetn]

It downclocks the CPU when it overheats

[zlojack]

It downclocks the CPU when it overheats

I know what it does.

I want to know what setting turns it off

[ap4lifetn]

oh my bad, its CPU TM Function, cpu configuration > cpu tm function

although i left it on, and i haven't seen it downclock my cpu yet, then again, i only let it run at 4.3 for like 5 minutes lol

[zlojack]

Thanks!

....big snip....Note the most important thing: While Asus and Intel (rightly) scare everyone (read: uneducated) into thinking that 1.65V on the DRAM voltage should be the absolute limit before you reach for the fire-blanket, all that's really needed it to obey this: keep the CPU uncore voltage within 0.5V difference of the DRAM voltage and there's no problem. Over this potential difference and you’ll greatly increase the chance of CPU death, but it certainly won't happen instantly in a big ball of fail fire if you make a mistake.....little snip....

Can anyone confirm or deny this?

[herderien]

i think it was dr who on another thread ...with the exact term "wont go in a great ball of fire"

I'm talking about a 920, not the 965 on the screenshot. I did test more than one CPU you know

[roller11]

Every reviewer says the Core I7 920 has locked CPU multi, so 19 multi isn't possible, only 20 plus turbo is possible. How are people getting 19 multi?

[Chri$ch]

No, multiplier from 12 to 20 is unlocked. only above 20 is locked (or max 22 with turbo on one core or 21 on all cores)

[roller11]

Oh, right...kinda like the E6600, I forgot about that. So that makes the AC characteristics of the mobo all that more
important (regarding the Bclk).
Another question...are all the various clocks/multis adjustable independently? For example memory clock, unclk, QPI etc.?
I'm wondering if there are going to be other bootlenecks that will keep a 920 from achieving it's full
CPU OC .

[DeanZ]

anyone tell me how hot these are getting under a true...btw I'm hoping to join you but I have to wait for a little more funding before

[chuckbam]

Anyone know where I can buy a i7 CPU cooler in the US?

[Chewbenator]

You can get this adaptor: http://www.jab-tech.com/Thermalright...X-pr-4323.html

Only works for certain Thermalright coolers though. Anyone know if there will be converters for watercooling blocks? Specifically the d-tek Fuzion rev.1.

[Gligy]

Here is a pic of mounted Fusion v1
I didn't tighten the bolts on the motherboard left them loose so they can go through fusions plate holes than thighten the block down - the resulting pressure is very good - of course not so good as proper retention kit but until one is released I'm pleased.



P.S. Should change my hoses as they are two years old already!

[X.T.R.E.M.E_ICE]

No, multiplier from 12 to 20 is unlocked. only above 20 is locked (or max 22 with turbo on one core or 21 on all cores)

Does not matter what i try after enableing turbo boost i canot select 21x or 22x, computer boots into windows at 21x but as soon as i use ET6 to up the speed the turbo turns off.

There must be something wrong. It would be good if Setfsb worked with Gigabyte EX58 Extreme.

[ap4lifetn]

U can't select it, the chip does it automatically. If u have turbo mode on, do something demanding, the multi will jump to 21. If you disable 3 cores, and do something demanding, that 1 core will have a multi of 22x
