March 20, 201114 yr Tried lower voltages? What about temps? tried lower pll, vcore. temps +40C air(bios), -20 SS(with small SS).
March 20, 201114 yr Wierd. I know for contra-efect when going deeper in minus but -20C is sweet spot temp for most sb cpus. Are you using b2 or b3 version of ud4? And the latest bios for it?
March 20, 201114 yr b2, latest bios sux for air. i will try it for ss....i think i need change mobo)))
March 20, 201114 yr b2, latest bios sux for air. i will try it for ss....i think i need change mobo))) That's for sure.. I don't like this board. I've B3 version and it's damn hard to work with it...
March 20, 201114 yr Hard to believe :eekSure you didn't forget to turn PLL overvoltage on or something? Nope, altho I eventually got vcore down to a stable 4.75v with pll set to 1.7v. Ah well, just bought another one, Batch L041B213T, will be back later with the results.

March 22, 201114 yr Crew L051B163 A1924 Lots of volts and 10c water! 5650mhz boot windows. (board cant clock blck in windows..). EDIT: Fixed it... just install MEI driver. 5655mhz pifast done. 56 multi. http://valid.canardpc.com/show_oc.php?id=1722486 Edited March 25, 201114 yr by Vivi
March 23, 201114 yr 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.

March 25, 201114 yr Crew nice vivi. how do you have done it to raise bclk in windows? with which program? 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 >_<
March 25, 201114 yr 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?key=0AomM1OP8WsDUdDd1VjNqU2Z6bW1LX0tqZVVndHBaU2c&hl=en&authkey=CIDij5kG maybe some one could add some analysis and graphs to it, so its easier to spot the best batches. cheers bubba
March 26, 201114 yr CPU #3: i7 2600k Batch# L045A912 #2417 http://valid.canardpc.com/show_oc.php?id=1709100
March 26, 201114 yr 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 >_< how's the ambient there in the highveldt? Must be one hotbox
March 28, 201114 yr Best CPU I've found so far from random untested ones... 3103B332 (Costa Rica) #4469 55x works Gigabyte UD3-B3 board on air http://hwbot.org/community/submission/2147345_linuxfan_3dmark03_geforce_gtx_570_131462_marks?new=true 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.
March 28, 201114 yr Hi, sorting the list massman posted in the first post, copy at google docs https://spreadsheets.google.com/ccc?key=0AomM1OP8WsDUdDd1VjNqU2Z6bW1LX0tqZVVndHBaU2c&hl=en&authkey=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 bubba Edited April 6, 201114 yr by bubbahotep
March 29, 201114 yr 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.
April 1, 201114 yr 2600k 3049A287 Costa Rica 1501 got here today. Will report back later when I fire it up in the UD7.

April 4, 201114 yr Just got: L041C238 #3242 Testing under SingleStage: this cpu really sucks monkeyballs - 53x100 = freeze during windows load, max boot 52x100 ... what a crappy piece ^^ Edited April 4, 201114 yr by SoF
