Is there a good i7 3770K batch number? - Page 19

Any idea on which should I be looking for?
I have the same chip as you, got it from MC Tustin, CA. I haven't really started messing with it yet....it just booted into Window @ 4.8, 1.35v.

I will report back later after I install and OCed PCB in my Auria lol

They did not. But he pulled one out... I looked at it... then pulled another... and looked at it. The first two were the same as the one I had before that were exactly the same... and then this one came up and I took it. Since it was said it was a rare batch, so it worked out for me.


Paterson is the only one in Jersey.

OMG... mine did not boot until I was into 1.4v for 4.8. Guess maybe batches don't matter much? I am testing 4.5 at 1.23 right now and it seems like it's running fine. Been going on for 15 min... Once it hits 30 I'm gonna try 4.6.

4.8 stable at 1.44v. Temps are super high... mid 90s, but while just normal gaming and doing normal stuff, never above 61C. So I think I'm happy. I was not able to do 4.7 at 1.46v before with the other two chips. So this one is WAAAYYY better. biggrin.gif

Batches can be all over the place, people have bought several at a time of the exact same batch numbers & end with with no two overclocking alike.
Sometimes particular batches can have a better than average chance at getting a good chip, but the same batch can also have terrible chips.

Someone posted something interesting either in this thread or another 3770k batch thread a while back, specifically regarding not the batch number, but the serial numbers:

Decent One was 0234.
Awesome was 1122 or something like that.

Theory is that the ones that suck are less than 200 as they probably are the edges of the wafer, and the sweet spot is around 1000 on the serial number (saw another batch 3232a610 chip serial 2522 4.8ghz 1.32v). 2000's seem good.

Good luck!

Well it looks that without changing other settings or voltages (like vtt) and with my current temps, 1.224v is where it's staying. I tried 1.200v and 1.212v and neither are Prime stable for 4.7GHz. But that's fine, I'm very happy to run my chip at 4.7Ghz @1.224v 24/7. biggrin.gif

Seller said the same thing where i bought my cpu. He gave me 1152 serial. But according to list my batch 3223A is not something to write home about. But I have not tried really ocing smile.gif.

[edit] running 4.0 with auto voltage (1.2V I think). At 4.5 with auto voltage temperature was crazy like 95C but I don't remember what voltage chip was running at

Hoping for a good cpu!

Well my luck with the IB setup went from bad luck to s*** out of luck today when the electrics shorted in my room socket resulting in most of my build being dead. I am not sure what I can get RMA but the CPU is in the process of return at least so when the build is back up and running ill have another batch to add to the list. I am praying for a good one this time but in the meantime time to get an electrician to find the problem since this is the second time in a matter of a few months.mad.gif
