i just got back from mc all they had was same batch left L041C123 and all i had was $200:) 55x 100.1bkl 1.575 ish real max temp was 90c 89c 87c 91c for 3d06 cpu tests even booted at 56x but i had 1.635 in it so i shut it down after it cleared windows.... nowww i have a chip for dice to push :yepp:
i just took a quick ss when i booted the first time at 55x just incase in crashed.
so good luck to you and the rest of you guys may your chips be high clockers :up:

All of this take less than 10 minutes of the cpu life

L051B138 can boot at 55x100 and do Memtest, but it can't boot into Windows. It wil just get stuck at the Windows startup logo.

max multi tested 55x
max mhz tested 5550 ( run everything 3D and 2D )

Does anyone know why I can't boot at anything past 51x (ie: 52x+). It would just get stuck at the Windows startup logo.

Same here, max multi 54X and max mhz 5.5Ghz and a hair above that will freez windows

L050A853 under SS again...a bit more BCLK up then max..

Your cpu max multi is 51X, You can try up BCLK to find max/mhz wall

Guess this chip aint too bad afterall :D Blue-screened at the last iteration of 32M but got the 1M no problem.

Any ideas why I'm able to boot and do a Memtest at 55x100, but wouldn't boot into Windows?

I never really use memtest with SB. Don't know why, but I came across a lot of 51X windows bootable 2600Ks. Some of it can go 51X 102BCLK and hit the wall.
Neither good air or cold can help

The latest Memtest86+ 4.20 is 100% compatible with SB CPUs and able to detect the CPU, speed, cache size and the whole 9-yard. It ran w/o any errors as far as the memory stability is concerned. It cannot, however detect the OCed speed, just the default speed (3.4Ghz) and not 5.5Ghz.

hey thanks
56x np on dice :) 5650ish seems to be all atm.
not that great of score i'll work on it and see if i can get a piece on dice on the card too.:D

To you guys that have gone through many 2600K's - is a 57x so rare that you have only found one? How many of you have found more than one?

Played with some offsets and llc settings. Wonder if this gonna 8hr prime stable also.

56X max. but Mhz wall @ 5.65Ghz, the other chip (same batch) maxed @ 53X

Avoid Costarica early batch 3005A749, mostly maxed @ 52X:(

@Dumo, where did you get BIOS 1303 to play with for the M4E? Mind provide a link?

Thanks for the heads-up. If I will ever see a Costa Rica batch here at the local MC. They still have tons for L* batches in their display case. Seems like none one is buying anything. The same batch and SN# remains day after day.

:clap:

you have great luck, I mean I know it is not a 57x but that chip is nicer than most:up:

shi(f)t I just saw your timings, killing it as usual:shocked:

That is certainly one of the better ones. Nice chip.

Binning Sandy Bridge is extremely easy.

- use HS fan with easy mounting
- set Vcore to 1.55V
- disable HT and 2 cores (to not make it overheat with crappy HSF)
- increase multiplier

You just need to see the windows OS options, not actually boot into windows. If your CPU can show the different OS options, stability will just be function of Vcore and temperature. If it doesn't show the OS options, you will never get it stable anyways, so you might as well ditch the CPU.

Usually, it takes about 5 minutes to see if the CPU is good or not.

With some CPUs, you do have the issue that some multiplier is better than the other for stability. For instance, my current CPU can boot at 51x MAX (~ 5145MHz). When trying to run near this max speed, I have to use 49x instead of 50x multiplier because it's a lot more stable.

But, that's something you don't need to test. With BCLK adjustments, you'll never get 5200MHz going or so. Multiplier binning is the best way."

is this pretty much how everyone is doing it? How do you get the windows option to load up? I dont have windows OS options it just goes straight to windows splash screen
