Sandy Bridge 2500K/2600K Batch and Serial Numbers - Page 27

Masterchief79 · #**261** 03-23-2011, 16:45

Core i7 2600K
# 2452: 5500 MHz (not maxed)
Batch: # L041C143

only runs barely 5300 on my P8P67 Deluxe, this board is just crappy for OC. CPU is pretested to 55x100 bootup, but there may be headroom, i couldn't test it myself yet.

No issues with the Dlx.. does 5600-5700 here... either you have a bad board or...

Hey hamti, i used asus Turbo V. on motherboard P8P67. BUT IT WONT WORK unless you install the MEI driver... took me long to realize this >_<

Hi,

I took the liberty to convert the list in the first post into a google spreadsheet that anyone can edit.

https://spreadsheets.google.com/ccc?...thkey=CIDij5kG

maybe some one could add some analysis and graphs to it, so its easier to spot the best batches.

cheers

how's the ambient there in the highveldt? Must be one hotbox

Best CPU I've found so far from random untested ones...

Massman; Could you put the batches that are from other factories and do not start with L0 all together in order either before or after the L0 list, instead of mixed up in there? Might be easier to look thorough.

Hi,

sorting the list massman posted in the first post, copy at google docs
https://spreadsheets.google.com/ccc?...thkey=CIDij5kG

by final Mhz, the results are all over the place.

The spreadsheet is editable. so feel free to add your batch # and results!

It seems that A and B batches get better results around 5500 Mhz and above.

Also as the results are all over the place it seems stable results around 5500 could be more depended on the skill of the operator that on the wafer..

what are your thoughts ?

cheers

Hi,

Ive been running my 2600k at 5100 Mhz stable for a couple of days.

L 0 44 B 441 #0681

CPU Voltage 1.5 (vcore in ai suite 1.52)
Multi = 51
BCLK = 100
VRM+ at 75%
PWM = extreme
Phase = Extreme
VRM fixed at 350

its impossible to determine the max 24/7 voltage using the forums. no body has a clue, so I guess we have to find out.
