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

[bro20000]

Shows how unlucky I am. I've had the chance to grab that B243 and a B208, chose the latter, and I'm not sure, it's either the chip sucks at OCing or my board sucks at OCing. Both of my chips max out at 5Ghz with 1.50V. Could just be the board, really don't know the real answer at this time since I only have one board to test the two CPUs.

Nice all we need now is one that hits 60x!

This L042B243 XXXXA1174 is a monster when freezed. My single stage calm and cool. Too bad Biostar board somehow stuck @ bclk 99.7

58X - 1.57Vcore bios - LLC disabled

You're the first person I see with 58x multi! Awesome batch, everyone get this one!

Jcniest5, heres..

L042B208 53X(2 pcs)
L042B291 52X
L045A998 52X (2 pcs)
L037B224 52X
L042B243 53X (1 can run 58X)
LO50A853 53X

Now I believed that its the cpu, most walled @ 53X and a few out there that can go >54X easy. Batch # not a factor. For me is 1 out of 9 2600Ks
Problem is...no good mobo on sale

I agree ... but still congrats on finding that special chip! and your other sample with the same batch walls at 53x?... Batch hunting isn't easy. I've tested six 2600K to date and would like to find one that will do 55x (or better).

What does it do without freezing and where can I get one? I havent seen one very good one yet here in Aus, on our forum our best cpu does 52x....

Has anyone tried L051A954 and L051A964 yet?

Looking at HWbot, batch L042B074 has 7 entries with the lowest clock being 5188. Bet I won't find one of those at my local store today.

really nice CPU

this is actually the max clock of my CPU (boot from bios)

1.625v 75% LLC in Bios (idle 1.632 / load ~1.61v)

[Sam_oslo]

x58 is a really good one

Maybe these CPUs are unlocked after all

Where does hwbot show the batches?

Hey guys, I have an L040B208 that hasn't been opened yet and I p[lan to build the system this weekend. I can still exchange it at a local TigerDirect store, but I'm not sure what other batches they have in stock.

I'm a bit nervous that it's apparantly one of the older first shipping batches, but the results on this thread seem pretty good, although the volts needed are perhaps a bit highjer than some of the newer batches.

Would you stick with this L040B208 or try to find a newer batch? If so, which one(s) should I look for?

Stick with it mate! I have a L040B307 and that clocks like crazy up to a 55x now! Even if you get a newer batch it isnt certain to clock well luck of the draw!

My core 1 temperature is way lower than the rest, or better put, the rest are higher than core 1. I already tried a little more thermal paste, but it doesn't help. Any ideas?
Measured with RealTemp, running IntelBurnTest 20x max.

I always see the same thing till I lap it. I lap all my CPUs. More than likely the IHS isn't flat. Thats the only way to fix something like that.

B208 is considered a very good batch ,you won't know till you try

I too have a L040B208 and mine can do 56 multi. Do not trade that one with out testing it as you might be lucky.

I went thuogh all pages i may have missed it but anyone see 044A892 before?

1 week to play using this batch was ok
x54 np up to 101 bkl,x55 boot not 3d stable thuogh
1.55 real ok 54x 5400 was pushing 1.60 here but it died soon after

[flesheatinvirus]

That is a killer 260 score right there,nice work.

A mate of mine has this BEAST- batch L041C124

Good one.
I've been looking for these rare C-batches. This is the second one I've seen, and both has been doing really good.
Just after the resale I said: C-batch seams the way to go in tis round, and now this beast proves it.

[jcniest5]

Okay, so I went and got the L042B243 and I'm testing it now. So far it's doing worse than my first two CPUs. Can't even pass 5Ghz with 1.50V (LLC Overvoltage Enabled). Is my board the culprit?

The problem with SB batch hunting is there can be a big difference between chips within the same batch. I had three samples from the same batch and there was an easy 300Mhz difference amongst them with the same BIOS settings. That sample probably has a higher VID.

[crossg]

Wanted to see if my chip (a bit of an odd batch L038A660) would boot to 53x and 54x. 53x yes, 54X no. Requires more than 1.55vcore and bios says cpu overvolt (F1) and wont let me go any higher. In windows it'll go to 54. Really just to see if it would or wouldn't boot. Looks pretty average to the newer chips. I can bench at 5200 with this so I'm happy with that.

Very nice vcore. Looks like C batch has some winners also. Nice work.

[Ket]

Batch is L049A796. Haven't quite pushed to 5GHz yet but this chip is starting to look good.. 4.7GHz @ 1.3v

[flesheatinvirus]

That could be a killa chip.
