Love my explanations today!

Another great explanation for the novice user! +Rep

So, I returned the 3570K to MC today, and they still have the $229 deal going on for the 3770K's today and even had three left! Good thing I went before lunch as they were going fast!
I also picked up some new memory to play with - Kingston Hyper X Predator 2133 - hope they OC good, my Crucial Ballistic Tactical 1866 went up to 2133 before I stopped trying.... Warning: Spoiler! (Click to show)
3rd 3770K & 8GB of Hyper X Predator 2133 to play with!
3rd 3770K & 8GB of Hyper X Predator 2133 to play with!
I will see if this 3770K is delid worthy once I get a chance to install and test it out! Hope I finally get a decent chip, but sadly it has the 322... batch numbers that have not been very good chips so far for me...and I went through all three they had left and they were all the same... frown.gif
Please - wait for a razor blade - we do not want you to lose your chip! No need to rush.....
I am so sad for you. Maybe it is just the IHS touching the nick, or some other small adjustment...hope so.
Look it over to see if you can get it running again and let us know what you find and how it goes....

does MC return (for a refund) policy include an open box?

I just tested my new 3770K and it was batch 3226C (26th week, lot C) and it's same crap, max clock with voltage below 1.52V is still 4.8GHz (1.400v under load), while 4.9GHz calls already for something like 1.56V ... I think I will return it and take my chances again LOL!

ehh, so far 4 chips tried in recent months (all costa rican, batches 3219B, 3224B, 3226C and 3228B), none was really good... only one among them (3224B) could do 5GHz fully stable at something like 1.56V (which is still crap in my book), but that one was ran on a faulty MB ... so it could have been degraded already when I got there, crap crap crap. so annoyed.

***.

wondering what batches other people received from MC recently ... so far production weeks 26 and 28 are stinky ones. not sure what to do ... perhaps I should start selling chips I dislike on ebay as delided ones and make some money while looking for a better batch LOL! I'm pissed off...

Sorry to hear about your bad luck today. Yes, MC does take back opened IB's if returned within 15 days. I returned my 3570K today for a full refund. thumb.gif

I then bought a new 3770K for $229 - another 322xxxxx batch (all they had), which was as good as all the other 322xxxxx batch I have bought from MC. That's not too good.... frown.gif

Interesting though is that the IMC on this new 3770K is much better then the IMC on my older delidded 3770K. Even the 3570K I returned today had a better IMC, yet my delidded 3770K can OC to 5.2GHz while the other 3770K and 3570K were only 5-5.1GHz chips.

Found this when bringing my 1866 mem to 2133 on the 3570K, while it will only do 1866 on the delidded 3770K. And then my new 2133 mem can also only do 1866 on my old delidded 3770K while doing the full 2133 on my new 3770K.

So now I have to decide if I want to stay with the delidded 3770K that OC's a bit better, but has a IMC that will not allow mem to go beyond 1866, or delid the newer 3770K so that I can use my 2133 mem sticks, but have lower OC's (and no return of the $229).

I really wanted to have both - higher OC with new 2133 mem - but have to decide - I gues smartest thing would be to return the new 3770K and the new 2133 mem and just stay with the delidded 3770K and the 1866 mem......bummed.......

thanks PCW,

I am still thinking on the plan of action for myself ...

could you be more specific about your batches? like first 5 letters? 322x means pretty much "Costa Rica - Year 2012 and production weeks between 20 and 29" - that's a lot of possibilities and at least 1 golden batch in those numbers wink.gif
also the lot number (usually B or C - 5th digit/letter) also have meaning as they differ, sometimes vastly hehe biggrin.gif

anyways, I think I will return my current chip (3226C) to MC in a week, nothing good of it despite promising results at first, can't get stable 4.9GHz <1.52v vcore, even though it's fully stable at 4.8Ghz at 1.40v under load (Cine, IBT) and it can boot 5GHz with 1.40v+

The one I received from Intel (3228B) I could either send back under another overclockers warranty or sell it as is.

Kinda sucks to have two brand new 3770K chips of different batches and none of them can do even 4.9GHz ... sad.

I personally never had a problem with weak IMC, but it could be my memory operating it differently. among all 4 of my 3770K chips I had, I can always run 4 sticks at 2200MHz or 2 sticks at 2400Mhz. my memories were rated at 2000Mhz @ 1.65v though, it's an older type (Mushkin 996990). I am still waiting for some decent memory to show up on the market, preferably something like 2x8GB @ 2400MHz @ 1.50V ... at a decent price wink.gif

@PCW Its hard to believe a 3770K can't run 2133 mem. These have strong IMCs and usually are good up to 2200. Maybe a wrong setting or something? Have you tryed to up VCCSA/VCCIO a little to see if it helps? If i had to choose between higher cpu oc or mem speed, i would go for cpu speed ofc thumb.gif

@Feniks, if you go for speed i would get some 2x4gb 2800+C8 sticks biggrin.gif 2400 is too mainstream tongue.gif

A bit off topic but looks like Haswell will be difficult to delid if they come with TIM instead of solder, those little square resistors that are gathered on the bottom middle are now under the IHS! Definitely take a lot more skill to delid if Intel uses the cheap TIM again, they got zero competition so I'm guess they will.

only pic i could find so far, you mean like this right?

o, it wasnt only the tim intel used, it isnt a bad tim , but also the distance between ihs and die,
that makes the temps go up that high..
