4770K	L317B756 0575	4500 1,175VSuperPi32m pass	5000 Load OS 1.4 fail

I haven't had a luck with 4770K yet.

I have access to these 3 i7 4770k chips. If I had to pick one what's my best bet? They're sealed so I'd really like to pick the best without opening the others. They're are all Costa Rica, and there doesn't seem to be much data in the op's spreadsheet on these style batch numbers.

Come on, opening a box it's simple )

From what I have seen with my Costa batches, it's not really gonna matter a lot.

 

Just pick one with your eyes closed. If you are lucky, you get a good one, if your luck is as bad as mine, all three are average and it won't matter :P

Hi.

 

First post here, so hello everyone ^^

 

I got two new 4670k from amazon today.

 

As weird as it is, i got two totally different batches, and of course plan to try them out and see what oc i can squeeze from them.

 

- Costa Rica batch: 3315B355

- Malay batch: L316B421

 

I tried a quick search to see if anyone got the same batch to compare my future results but got nothing out of it.

 

Do you have any informations about these batches?

 

Also, I'm quite paranoïd about getting DOA product so I don't open it and usually ask for an exchange when an item box is damaged. Among the two processors i got, one box has a cut from a cutter on the box, and said box also has a damaged corner as if somebody made it fall on the ground (the costa rica processor box is 100% clean in comparison). If that happened, could it have damaged the processor in it???

 

Here's two pictures:

What do you think about it? Should i ask for a new one? It doesn't cost me anything where i live because Amazon just swap items without question when a customer finds that an item box is damaged.

 

Thank you in advance! ^_^

k,i had some time to test the cpu,all the test were made with 2 vents ,one of 3000 rpm and the other one of 1200 on prolimatech Genesis at 25 degrees room temperature..

Ring/cache needs 1.165v for 4900 .

The cpu works like this on Gene VI :

 

Boot :

4.5 at 1.05 v

5.0 at 1.21 v

5.1 at 1.27 v

5.2 at 1.35 v

 

3d :

4.5 at 1.07 v

5.0 at 1.24 v

 

 

Tested under dice and it works 3d at :

 

5.9 Ghz @ 1.58v (boot at 1.55,maybe lower) Vccin @2.120v and Ring at 5400 @ 1.4v

5.7 Ghz @ 1.45v Vccin @ 2.050v

5.5 Ghz @ 1.35v

 

I will try to push it further in the next session. :) I don't want to fry it ...yet.

 

Batch L309B384 .

 

Under Ln2 it acts differently ?

Congrats, that's a really really good chip :)

It might be golden CPU if it scales and has CB -120C and lower
