TPU's Core i7 Overclocking and Feedback

Hey guys I'm back after a ban (:nutkick:)

Have been reading all your post. Amazing results guys. i7 just rocks:rockout:
 
welcome back :D Stay fresh Mudkip.
 
w00t booted @ 4.3 and got into windows, but alas with no voltage adjustments she blue screened after about 10 minutes of L4D

205x21 - and 1.3625v on Vcore/QPI

back down to 4.2 for now which is rock stable, I want to see what she can do but im not interested in too much more voltage really.

coming from a Q6600 its an AMAZING difference to have a chip do 4.2ghz @ ~1.35v
 
The past month i've been fine tuning my overclocks.
I tried overclocks till 4,2 Ghz. Haven't finished overclocks with the 21x multiplier yet but that will come later.
Hopefully these overclocks are helpful in any way for you guys.

the voltages posted are BIOS voltages and not CPU-Z voltages, also every overclock is with HT on.


21x multiplier:

4.2 Ghz @ 1.285v

3,8Ghz with 21 x181 @ 1.13125v / mem @ 1810Mhz

20x multiplier:

3,8Ghz with 20x190 @ 1.16875v

3,6Ghz with 1.10v

3,6 ghz with 1.10000v @ 1800Mhz

3,4 Ghz @ 1.03125v

3,2Ghz @ 0,98750v

3,0Ghz @ 0,94375v

2,6 Ghz @ 0.89375v

summary voltage list:

20x multiplier:

3,8 Ghz @ 1.16875v
3,6 Ghz @ 1.10v
3,4 Ghz @ 1.03125v
3,2 Ghz @ 0,98750v
3,0 Ghz @ 0,94375v
2,6 Ghz @ 0.89375v (multiplier 12x due EIST and C1E on)

21x multiplier:

4.2 Ghz @ 1.285v
3,8 Ghz @ 1.13125v

System used:

Gigabyte X58 UD5
Core i7 920 D0
OCZ 3GB 1600Mhz low voltage
Scythe Mugen 2 with MX-2 TIM

Software:

OCCT
LinX x64
Realtemp
Gigabyte EasyTune 6
CPU-Z

Conclusion so far:

overclocking with the 21x takes LESS voltage.
The voltage difference between the 20x en the 21x multiplier depends on the overclock.

how higher the overclock ,the bigger the difference between the 20x / 21 x overclock voltage will be.

PS. this took me a lot time to test LOL

nice to see you back man. kinda missed you in a non gay way

LOL!

Yea nice to see you back :p wonder what you were banned for :wtf: probably because of the i7 being discountinued or not mess lol...

nice results btw :D 3.8 on 21x with 1.13xx V seems nice to me :p
 
I am happy that the UD5 does not throttle down the cpu multiplier when it is under load, so now it can run at x21 at all times :)
 
Some quick overclocking results with my new UD5, I am loving this board :)

4.2 (200 x21).png


Been able to get it up to 4.3 with 1.39 volts, although I have not taken the time to really stress test the clocks yet. So many BIOS options, especially for the RAM.
 
:laugh:

Don't forget to give me heatware.
 
Hey guys. I picked up a i7 920 D0 batch# 3910A313.
I have not found any info on this batch BUT WOW
does it clock VERY well. This thing can do 4.5Ghz
easily. Unfortunately i do not have the cooling
setup to handle it. Anywho here is a little screenshot.

so its been awhile boys how are the D0's stacking against the C0's? should i grab the stepping upgrade?
 
They are C0s that require less voltage. Some do or don't OC as high as the high end C0s. Most D0 put off more heat than C0. It's not the craziest improvement, but if you have cash to burn then go for it.

C0 is a piece of shit compared to a D0.

im surprised you couldnt tell by our results in this thread

you wouldnt even have to have read anything... just look at the screenshots

Someone's just grouchy that he never got a good C0. ;)
 
I purchased my 920 in march of 09' at frys electronics when they had the sale. I have the bios cpu configurations all disabled except for HT and speed/turbo stuff disabled. I am able to reach 3.4ghz at 1.45v. Anything over that its unstable and I wont dare to go higher. Temps are 40c degrees idle and at 70c max at 100% at these settings. I dont know why it takes so much volts, but I think I got a shitty core i7. I am able to hit 24,000 in 3Dmark vantage.
 
4.5 volts!? you mean 1.45 I hope, and even then it's high as hell!
have you ever tried just going AUTO settings and raising bclk?
 
See? not that's a C0 :p
 
For 1.45 volts those temps are reasonable, but seriously, I could take my C0 up to 3.8 on auto settings by just raising the BCLK. And that's the same chip I never got pas 4Ghz stable.

Do you mean only the voltage settings on auto or everything including the cpu settings and turbomode enabled?
