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

[andressergio]

These Ivy chips are crazy!! There's got to be something missing right? Internal PLL overvoltage or something.

4.5GHz IBT Stable @ 1.14v
5.0GHz 32M Stable @ 1.32v
5.2GHz 32M Stable @ 1.525v
5.3GHz needs 1.65v just to run!!!!

grats C-N great chip you got there !!!

[rge]

My 3770k is instant bsod at 5.2ghz, but 5.1 can bench all day at 1.48.
ram is 2000mhz, 9,9,9 27, had to crop out cpuz memory shot, so pics readable.

And 24/7, 4.7ghz with 1.308 load vcore, 12hrs prime

[C-N]

Bet the temps were off the chart at those voltages.????

That 5.2 screenshot was on a TRUE 120 with a slow fan & as you see she hit 70oC at 1.65v it was 92oC!!!!

grats C-N great chip you got there !!!

I have no idea really just want it to go faster lol

So far, is there any trending with the 3570Ks yielding slower OCs than 3770Ks? Not quite enough samples in this thread to tell one way or the other.

Hi
3570k

good temps at 4.4
seem to raise at 4.6

Is HT really all that useful in gaming and stuff? I'm trying to decide between the 3570 and 3770. I mean when each core is running 4.5ghz+ is it not fast enough to chew through tasks?

[Endgame]

HT isn't really useful with gaming, but it is on some scientific processing, video editing, etc. The binning may be better on the 3770s, though, meaning you may be able to get a better overclock on the 3770s. I understand this was the case with the 2700Ks, but I don't think there is enough data out there yet to tell one way or another with the 3770s...

[situman]

Really does wonder if it is worth the huge premium, relatively speaking.

I think this is the first chip I'm going to pass on Hyperthreading with -- considering that virtualization support has been removed from the K series, I don't see much reason to have Hyperthreading for my usage patterns (I game with my primary PC and turn old hardware into servers). I don't think the extra cache on the I7 is really going to make much difference gaming, and I'll just put the saved cash toward a second or third vid card.

[Budwise]

I went from a 920 to a 3570K and personally I havent missed the hyperthreading. But i would miss my $100

[situman]

Budwise, how's that cpu/mobo combo treating you?

[zoob]

After adding various expansion cards, I've had to increase voltage to keep stability on my 3770K

45 x 100
2 x 4GB Samsung HCH9 DDR3-2133

From no expansion cards with a bios offset of +0.005V, using IGP.

Then adding:
+ X-Fi Titanium HD PCI-E, increase by 0.020V, for a BIOS Offset @ +0.025V
+ Radeon 7770 PCI-E, increase by another 0.025V, for a BIOS Offset @ +0.050V

I am wondering what I will need to increase to move up to 4 x 4 GB.

[PolRoger]

I've been testing two 3570K from batch# L204B450. They both seem to o.c. in a similar manner... 44x with ~ 1.15v (load), 45x with ~1.20v (load) and 46x with ~1.25v load

11+ hrs. Folding at 46x:

[Cecil]

Will be leaving in a bit to get a 3570K. Is there a certain batch to look for yet? Or are A/B/C better for daily water?

[Budwise]

Budwise, how's that cpu/mobo combo treating you?

Quite well thus far. No problems aside from the motherboard not liking my 6950 flashed to 6970.

[Cecil]

Didn't know what batch to go for, so I picked a c batch close to center wafer since Bs seem pretty hot. Got a 3205C109.

[LagunaX]

Good call Cecil.
B's have not been super impressive for most.
How did u get to pick?

How can you tell if the sample you've picked up is close to center wafer?

Is it a low or high vid chip?, yes center should be better.

At MicroCenter, had someone look around through a few of them.

Last couple digits, lower the number, closer to the center. 15 and less is center.

Is it a low or high vid chip?, yes center should be better.

Just got home, have a lot to tear down and work on tonight. Will probably throw it up on a rack with a Hyper 212 Evo to get a baseline.

[trans am]

grats that is on air? 3570k 5.3? that could be a golden chip. are you pulling my leg? that chip needs to be on ln2.

[Dumo]

I'm looking for s/n 2Vxxxxxxx4000~4099. Lol
