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 :D.

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 :p

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.

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

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.

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)

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)?

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.

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

Got another chip to play with.:)
