i5-2500K/2600K batch number and o/c results

[Dumo]

Yep, even my L04B243 S/N XXXA1174 can run 32m @58X, but it was at 99.7 BCLK though. If it can go with >100 BCLK and finished all 3Ds then probly its a real gem

[EagleRock]

I have heard that L042B076 is one of the best, Is that true? If so then i'm very lucky

Imo, we can't tell by the same batch#.

It probly goes down to "same batch #" and the last 4 digits of S/N#
SB is totally a different animal

Wouldnt there be no difference though? like .3 ?

[Dumo]

I will find out soon with UD7

If its a no go then it will be the same like those 54X with >105 BCLK 2600s. Probly it isn't a multi wall but freq. wall (5800+ @ 100+ BCLK)

I think I'm gonna stop trying to find a golden batch for the moment. It seems like my motherboard is the culprit of not being to OC any of my 2600Ks (L040B305, L042B208 and L042B243) past the 5Ghz ceiling. It seems they all max at that speed. I will check regularly at the local MC and see if any of those golden batches that have been mentioned around here show up there. If one shows up, I might grab it. I actually want to order an Asus Maximus IV Extreme from one of the Candanian stores, but they aren't shipping to the US. I really wish they do. Maybe a Canadian friend can help me obtain one. Otherwise, I will wait until April or May when things are back to full swing again.

Yeah, Intel is having so much fun watching us chasing pheasants in the field.

[EagleRock]

I think they are more busy trying to make us new motherboards

Yes, but that's the Motherboard Department, the CPU Department is just watching us playing the game they put in the field.

[aussie-revhead]

Do you think Intel knows which ones are the good ones and which ones arent, so they just sit back and laugh at us until we work it out?

[Lsdmeasap]

You know they do, Dr.Who is trying his best to not stop in here and give us any hints

[aussie-revhead]

So you reckon they have no idea which ones will be good and which ones wont? Just send them out and see what happens?

...

[Lsdmeasap]

No, I meant I'm sure they do know what batch or other spec is the good ones, and they probably have plenty of those held back too!

[aussie-revhead]

... hmmmm maybe saving them for 2700K? Same thing but twice the price ?

[Ket]

Nah. Intel probably hold the real golden chips back as their cherry picked samples and ship out "all the rest".

[Sam_oslo]

This Intel-batch-business is a tricky-one each time, but we are going to crack it, soon or later.
Intel has total control and a strict QA. These variation in OC-headroom is not a random one, either by die-peace or other stuff. Intel decides to tap good chips and they do it for a short while, and they know where to find it, with total control.

They seams to have changed to a new trick in this round, those rare C-batch# seams to be replacing the good B-batch# from last round.

[aussie-revhead]

Has anyone seen C chips in their local store?

Microcenter in Westbury NY USA...Grabbed a L041C108-1499 on Friday. Just like the L039B214-XXXX I have boots 54 out of the box at 1.48v. Only tinkered but it does the exact same thing on the Asrock Extreme6 as the L039B. 55 multi blinky cursor lol It does (C Batch) however run 32m at 5.4 1.425v BIOS set Vdimm and vtt~.5 difference rest AUTO. The B batch takes a bit more voltage. Shame with the recall I'd love to test it on a better board/bios but that will have to wait I suppose...

[Ket]

Everybody who has clung to their P67 like a vice has to wait ATM. Won't see any movement on the UEFI front from any of the manufacturers until after the chinese holiday at least. We may even be left out in the cold completely until the re-launch of P67 boards

[Alex-Ro]

When does that Chinese new-year holiday ends?

[Sam_oslo]

When does that Chinese new-year holiday ends?

Those guys work 24/7 and 356 anyways, LOL,

But I think we are going to see some slow-down, if not a total stop, in BIOS development for some MBs. Some companies may put everything on hold until new chipset arrives.

[Dumo]

At least at my local 3 Micro Centers 2600K and 2500K sale still going strong (even without any P67 mobo on the shelf)

On the week of 1/29 most of their inventory were batches L042BXXX and L050AXXX. Just last night all were L041Cs

Are they the 2600Ks or just the 2500Ks that have the *C* batch? I will be interested to get myself a *C* batch and see how it OCs comparing to the *B* I've got so far. At my location, all are still *B* and *A* batches...so far as of yesterday when I was there.

[Elloquin]

Woops...It was a 2600K.

[nijel]

My 2600K L041C108 from MC won't go >52. 52 boots to windows @1.4V, but 53 and up is a no go. Got 53 up to 1.62V and it froze in bios. 54 can't even boot. Is it the chip, is it the board (UD7), is it me...?
Hope it's the board.
24/7 LinX AVX stable 4.7@1.32V.

And BTW this batch already have seen 58xx GHz with x59 @1.6xV somwhere else.
