Congrats mate for those low volts 5GHz i guess if you up mem to 2400 or more you will need at least 1,4 but great chip :)Quote:

General speaking. Batch i don't think i could choose very much..
Or it is a lottery. :(
It´s a lottery. Even Chips with the same batch are different. Costa Rica and Malaysia have good Chips and bad Chips.
I bought now a 3770K Batch 3214C557 (still in the mail) where the 3 = Costa Rica and the C give me hope for a good Chip, but there is no warranty.
Absolutely, binning is the only way.
Finally, found a decent costa:D

Not so extreme like many of you, but this is what i got till now. Still testing with stock hsf. Atm my cpu runs at 4ghz with offset set to -0.080 (0.80v idle - 1.088v load), LLC standard, VTT 1.60v, Ram 1.60v @ 2133 9-11-9-28 1T. Room temp 26C, 29-36-29-32 idle and 90C max with linx/prime. Lowering VTT from default 1.80v to 1.60v didnt drop temp even 1C at load like some say.
A5G gives a red number if you set offset more than .065v. Is there any real problem with this because I am going to give a try with offset set to -0.090/-0.10v. I ll also try to oc ram at 2200.
congraaaaaats friend it was about time !!!Quote:

The three that I tried were all pretty similar (though the two 3770Ks were identical batches).
4Ghz 1V, 4.2Ghz 1.1V, 4.4Ghz 1.2V, 4.5Ghz 1.25V all LinX AVX stable.
What volt did that take on ram RoyQuote:

3770K 5Ghz @ 1.30V prime stable for 20 minutes just to see what the temps are: http://i404.photobucket.com/albums/p...304_20mins.jpg. It passed the hot 8K FFT test.
3770k 4.9Ghz @ 1.256v prime stable for 2 hours: http://i404.photobucket.com/albums/p..._1256_2hrs.jpg. Am using this setting now 24/7. So far so good.
3770k 4.8Ghz @ 1.216v 21 hrs prime stable completing all 70 FFT lengths: http://i404.photobucket.com/albums/p..._P95_21hrs.jpg
might try to run 4.9Ghz with the full prime test this weekend. 5.0Ghz might be too hot for full prime test even at 1.30v unless I take the IHS lid off (was thinking about it before I knew how it clocked --- not thinking about it anymore :D)
Ithink this is a golden one :)

You think? :lol: :up:

Great score, Roger!
Go grap some LN2 and smack that :banana::banana::banana::banana::banana:! :D
That is a solid chip though phase makes a huge difference with Ivy, it brings it back to Sandy levels.
i5 3570K
batch : 3218C290
it's a costa rica C chip? i think i read people being excited about these ones right? lol glad i got a good one, least it seems good so far.
4ghz 1.065v (1.072 load)
I'm on the stock cooler at the moment, as i wait patiently for my new true 120 bracket. So for the moment I'm just shooting for the 4ghz and seeing how low i cant take the voltage. no long stability test yet, as i've been wary of temps.
realtemp has been reporting nearly 80*C for any voltage i set to 1.075 or higher, i think one core hit 82* at one point. but 1.065 seems to be keeping me closer to the 75*C range at the moment.

@LN2 on the Giga UD3 :)

Next run with the Asus MVG :)
Goes to show batch means nothing with Ivy. Picked up a L204B450, and its the worst one of 4 that Ive had. 1.33V 4.6 fails LinX, and thats hitting 85C with an H100 push/pull on an open rack.Quote:

Tried to go as low on possible on cpu voltage while remaining at decent overclock..

You are not using AVX on linx, so I'm sorry to say your results are nothing but irrelevant :(
what is AVX? :) Well whatever been stable in LinX, been stable elsewhere without a single bsod/crash, so I would say "irrelevant" is too harsh of a word :DQuote:

You must have Windows 7 with SP1 and latest linpack to run linx with AVX.
