Actually all the screens ive posted have HT on, I turned it off to see if it made any difference while testing yesterday. All Ive noticed is that with HT on it runs a tiny bit hotter.

I also find it kinda weird that the GFLOPS in Intel Burn Test are actually about 15% higher with HT off vs On.

I've noticed around the forums some gamers turn HT off but other ppl with video tasks use HT all the time. Can't pin down any links but over at OCN there are some.

Just an observation

I'd understand that if you got the i7 at MC compared to an i5 on newegg. They're roughly the same price. Still I do like my hyperthreading

Rysandro · Feb 27, 2013

Yah I mainly opted for the i7 because I figure more and more game engines will start being coded with 8 or more threads in mind, especially now with these 8 (not sure if 8 or 16 threads) Core processors in next gen consoles.

Good point about consoles. They drive the market I suppose.

Can elaborate on PPL voltage and if it is safe to under-volt it. The reason why I ask is if I go 4.5 GHz using offset on 1.8 PPL (normal) , I set vcore normal and DVID to ATLEAST +0.025, HOWEVER, when I set PPL to 1.7 I can run 4.5 with normal vcore and -0.05. Is this odd, or am I not getting something?

EDIT: Screen

Sandy bridge needs PLL 1.8v.

Ivy Bridge only PLL 1.6v for stock and up to 1.7v for overclock.

fans set on low on the rad

You guys always seem to get good chips, or do you just bin a lot?

Says 1.8 in bios.

LagunaX · Mar 1, 2013

That is the default since 1155 runs Sandy Bridge as well.
Ivy needs less and just generates more heat and gets less efficient with higher PLL.

I use the lowest my board goes, which is 1.57v or something close to that iirc. Never ran into problems with instability because of it.

guitarfreaknation · Mar 1, 2013

Had some time to tweak today. This is what I got so far, and seems like the lowest possible vcore for 4.4 on this chip. (vcore norm, dvid -0.020, PPL 1.65)

Ze · Mar 3, 2013

Got my new chip, same batch as before (#3227C383)

Will be delliding tomorrow

LagunaX · Mar 3, 2013

Hope u bought the $29 warranty.

Razor blade at the corners first.

Dude can't believe you got the same batch!

Ze · Mar 4, 2013

I'm surprised

Before Delidding

And after

I didn't think it was going to be so much

LagunaX · Mar 4, 2013

Waiting for your 4.7 or 4.8ghz screenshots.

How did the delidding process go?

Ze · Mar 4, 2013

Went pretty smooth, was a pain getting all the gunk off. I'm testing 4,8 atm

Frogger · Mar 4, 2013

Got the external rad hooked up 5Ghz@1.28. Ran IBT@ maximum.. 83c top temp after 5 runs.

With GELID extreme. Going to have to order some Liquid Pro & see if Ican shave off some more C's

LagunaX · Mar 4, 2013

That is the best 3770k I've seen.

would of been good to test on ln2

Ze · Mar 6, 2013

Needed a bit more vcore than expected but everything is stable so far.

LagunaX · Mar 6, 2013

Well u knew it was a poorer batch but not too bad after delidding.

Are you gonna run 4.7 or 4.8ghz for 24/7 (knowing that you have he waranty)?

Ze · Mar 6, 2013

It's still better than both of my older chips, and I'll stick with 4.8 since temps aren't even high. It can bench at 4.9 no problem but requires a decent bump to get it stable.

DOM · Mar 8, 2013

Anyone have a 3236b806 ?

I keep my 24/7 rig with the chip from Laguna at 4.8 as well..........but.............

Got another chip to play with.
