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

[sobol]

Remove IHS and change for liquid pro u will be amazed of temp drops and stabilty

I've seen those suggestions already and I think it's good idea.
I did that several times in past on AMD's Athlon 64 Venice.
Although I think I've seen poll on hardforum that shown few people screwing their new 3770 CPU's.
I think perhaps leaving it as last resort option would be the best.

Any bios tweak suggestions? Perhaps increasing PLL to 1.9v or LLC to 100%?
I'm little bit rusted with my OC skills, since my last CPU was Q6600.

Just picked up a 3770K earlier this week. Batch is 3230B. Does 5.0Ghz at 1.330vcore under load. Going to be testing this thing further this weekend.

How's the testing coming along? Stable at 5Ghz with that vcore?

[IronAge]

Got one 3229A whch should be able to do IMC DDR3-3000 (post Code 55 @ 2933 and 3000) ... 4.5 GHz 1.12 4.8 GHz 1.264 ... under air.

[Ivanlabrie]

That 3229a seems to be really good!
Where did you get it?

[IronAge]

Got it from a guy who bought two from an an etailer called CASEKING in germany.

The other one of the same batch which he kept does 5.4 GHz @ 1.48 vcore with a chiller.

[Ivanlabrie]

Nice!
I got mine from a friend in Texas, I got it to do 5GHz at 1.48v on air and it's now delidded. Not a very good batch: 3223b
My former board sucked with ram and is now dead. We'll see how it does with my new MVG this weekend.

My new 3770k Batch 3229B068
Not delidded ( yet )







Recently instaled i test later...and i cut Ihs soon very soon!

- Edit -
Testing IMC 1400 Done!

[andressergio]

After a day of testing i luv this config


5GHz HT @ 1,472 load / 2666CL10-12-12-26 1T tRFC 128 TSWR 4

I got a 3230B370. So far stable at 4.7 with 1.29. What are you using for stability testing?

[flesheatinvirus]

I just grabbed a 3230B368 this morning but have not tested it yet.

[flesheatinvirus]

I think I might have finally got a good one after the last seven being crap this 3230 looks promising so far. I just finished some quick testing of 32meg Pi and loops of Cinebench R11.5 at 5G at 1.34v rock solid,not one issue and I am sure it can go lower.

[Shiranui Gen-An]

I have a pathetically weak 3770k in terms of IMC, code 23 when trying to boot at 2800. Batch #3228C131, Costa Rica. By contrast, my 3570k batch# L152B659 Malaysia chip can do at least 2800, if not higher.

[LagunaX]

Got the itch to overclock again today after a long hiatus (Diablo 3...).

Microcenter, Tustin, CA.

Batch#: 3231B415 - they had a lot of them.

Not delidded, quick 30 min air testing...

Needless to say, I'm McLovin' it!

More long term testing to follow sooner or later, looks like I might be ordering some Cool Laboratory Liquid Pro!

EDIT: 1 hour prime95 x64 v26.6 (no AVX, LOL I'm still on air) 4.8ghz @ 1.20-1.24v range on air:

Looks like that's my limit for now (load 79c) unless I delid...

[Dumo]

Can you do 5Ghz 4C/8T with 1.25ish 32m Laguna?

It seems like nice lovo cpu

Is SuperPi what you are looking for?
Is this a good result? Granted it's only at DDR3 2133 vs. higher ram speeds.
http://i246.photobucket.com/albums/g...70k5ghz32m.jpg

5GHZ 4C8T offset vcore ranged 1.23-1.25v.

[Dumo]

Awesome chip Laguna

3770K's stock @ local MC here in NY still full of 3228 chips.

[Ivanlabrie]

My 3229b444 cpu was pretty bad...
Needed 1.48v for 5ghz spi 32m stability.

I'm getting a new one from RMA soon, hopefully it'll have a nicer imc as well.

[hersounds]

3229B068

4.9 Ghz - 1.28 Vcore

[Ivanlabrie]

How much vcore to boot at 5ghz and run spi32m hersounds?
Seems like a similar chip to mine batch-wise yet it performs much better.

Also, how's the imc in it?
Thanks!

[hersounds]

5Ghz about 1.35 vcore SP32M...IMC is 1463 Mhz tested

[Viss]

3770K batch 3237B @ test on air. IMC is good on low volt but just a few mhz higher wont even validate, volts dont help

[Ivanlabrie]

Yikes, that's a nice 24/7 delidded chip right there...

[ante_ante]

Got a new 3570K today with batch 3234C264 , anyone seen this before? Just installed on my Asrock Z77 Extreme4 , will test it later and maybe pop ihs.

[hersounds]

Yesterday my friend buy an 3234C326 but not 35k if not 3770k
When he try the chip i tell you buddy
