Ivy Bridge i5 3570K/i7 3770K batch and o/c results

[andressergio]

Decided to disable HT on my L206B351 and I'm glad I did.
I might just keep it this way
Little bit toasty but it was a hot day.

Attachment 127122

nice McDown what are your mem speeds ? chip seems very nice, does it makes a lot of dif on vcore to use HT ?

[andressergio]

Right! As long as temps are good, give it as many volts as it takes to be stable. Unless you plan on keeping a chip for 10-15 years

Looks like I may grab some LN2 tonight

any results NoGuru ?

I usually run my Mushkin 994008 @2133 (I got it just for looks ).
With Ivy any voltage bump is a BIG BUMP and you need quite a bit. It's all about temps now.
With removed IHS I'm at 4.9ghz with HT at 1.39v Prime AVX stable

The original TIM under the IHS is replaced with NT-H1
23 degrees ambient

Higher frequencies even 5MHz more, cause BSOD under Prime95 AVX - In-place large FFTs, regardless of the voltage.

why u are using OFFSET vcore dont u have manual ? its better more idle than load of course

in case you wanna do offset here the best guide i found for asus but will do as well

good luck

Thanks for the link. But I don't think you read my post.
Anyway, I'm using offset mode because it results in lower idle volt.

[NoGuru]

any results NoGuru ?

No, place I get it from was sold out and everyone else wanted like $4 a liter.
Will try again for this Friday.

sorry but its no problem to use no offset at all, i tried lots of times offset and gave me some stutter on games

cheers

yeah i noticed that from 4.9 to 5 needs lots of food

cool you removed the IHS thats very nice but a task i cant risk to do

cheers

Upon my further googling, I've found close answers to my questions. Let me share and I hope this helps you with better understanding, too.

Please read 2 quotes below.

Offset voltage is a value added to the base voltage of your CPU. If at stock you have 1.1V, and you set +0.2 to the offset voltage, you are stating that the maximum voltage is going to be 1.3

Load Line Calibration forces the voltage you set in the BIOS through the chip, and gets rid of Vdroop. Vdroop is a drop on voltage which follows Intel specifications to avoid damaging the CPU. WITHOUT LLC, when you set 1.35V on the BIOS, while you stress test the chip, voltage might drop to 1.3 - 1.25 V. When the test stops it will go back up. So Vdroop only is enabled while your CPU is under stress. This means you will have a larger voltage when idle than while doing work.

Therefore you need a method of having a lower voltage when you CPU is idling. Enter C1E. With this feature, the CPU lowers it's multiplier when it`s idling, but also lowers the voltage! This is why Offset voltage is useful. It dynamically adjusts the clock AND voltage to what the chip needs.

Without Offset you CPU doesn't know what maximum and minimum voltage you want. It will just stay at the same voltage the whole time, while idling and while doing work. If the voltage is not very high, the degradation shouldn't be substantial, but it's always nice having lower voltage when you don't need alot of power. Why would you want to use 1.45V when browsing the web when you could do the same at 1.1?

Also, this inderectly lowers the temps a bit. With lower voltages the chip is less hot, but when it idles it also underclocks and the temperature difference is very noticable.

Offset mode gives you more stability at lower maximum voltages. When settings the voltage change it from fixed to offset. You will often get lower stable voltages than with fixed, that alone is a great reason to do it. The other reason offset is sweet is that it doesn't keep your processor at a set voltage. This allows you to save power, heat, and add longer life to your processor. Just start at +0.005V and work your way up. I was able to get it working at -0.010V (which when under full load was 1.23V) but it wasn't stable enough.

For my setup +0.005V = 1.28V under full load.

And a good post on Vdroop.

well finally i found my gamming config it needs a nice bump on vcore from 4.9 to 5GHz but im happy quad rad setup keep it cool

5GHz with PATRIOTS 2000 9-11-9-27 1T @ 2400 11-12-12-31 1T

very nice andressergio

very nice andressergio

thanks bud i wonder if on a Z77 results will vary too much for now i very happy that runs this way on a P67 board

[andressergio]

guys a question

on IB 102.1 x 49 = 5GHz consumes same more or less vcore than doing 100 x 50 ???

thanks in advance
Sergio

Did you manage to run CPU test of 3DMark Vantage on this speed without throttling?

next try is on liquid cooling and ht enabled, but i'm afraid of how many degrees i'll get ...

[Andrea deluxe]

able to do 4500mhz @ 1.16v

air cooling.

PS: i have lost a screen...

[p3gaz_001]

make some linx/ibt screen dude...

well i use it for gamming BF3, MOH, METRO, BATMAN, DIRT3 , DIRT SHOWDOWN and lots of games more for hours, CPU gets max 74C on BF3 on the hardest maps and my screen is a 2560x1400 wich pushes more VGA and CPU

i will try it for you maybe it does that

cheers

In my daily rig this cpu runs very stable at 5.3Ghz using 1.520 vcore. However, it needs a lot of juice to reach 5.6Ghz unfortunately. This 1M run was just for testing purposes, daily OS, no tweaks.

andressergio; Is that the patriots or the samsungs in the screenshot 5G2400?
