Pcjunkie209 Posted February 5, 2011 Posted February 5, 2011 I have that batch as well and so far it needs 1.50v+ to run at 50x100 (5Ghz) stable. Anything less then 1.50v results in BSOD. To me, 1.50v for 5Ghz is simply too high. i am 1.42v and running fairly cool still. any lower bsod Quote
SteveRo Posted February 8, 2011 Posted February 8, 2011 (edited) Quicky run. My 3rd 2600k, this one - L050A853, serial # 35043265A2642. wprime1024 @ 2min 21sec 594ms with 2600K at 5512.8MHz http://hwbot.org/community/submission/2121548_stevero_wprime_1024m_core_i7_2600k_2min_21sec_594ms Edited February 8, 2011 by SteveRo Quote
Splave Posted February 8, 2011 Posted February 8, 2011 w00t 2 more comming to day, cant be worse then what I have L040B705 *0233 Max cpuz = 5215 Max 32m = 5200 Max boot frequency = 5096 (x52) L045B005 *1138 Max cpuz = 5175 Max 32m = 5150 Max boot frequency = 5036 (x52) Quote
Splave Posted February 8, 2011 Posted February 8, 2011 both new ones are L045a912's 2616 and 2417 Quote
dumo Posted February 9, 2011 Posted February 9, 2011 L042B243 *A2771 = 53X max. L042B243 *A1174 = 58X max. Quote
Massman Posted February 9, 2011 Author Posted February 9, 2011 Updated! List is starting to grow nicely spot a trend between "numbers" and overclockability (if there is some, of course) you should be looking at the highlighted numbers from the ATPO, at least with cedarmills they tell a lot more than the last 4 digits you're asking people here...from what I found locally, "043" means the actual date of silicon production (for example E8600 with "823" are good no matter the batch) Where can you find that serial number on a tray CPU? w00t 2 more comming to day, cant be worse then what I have L040B705 *0233 Max cpuz = 5215 L045B005 *1138 Max cpuz = 5175 Heh, you must have the worst luck imaginable.

Massman Posted February 9, 2011 Author Posted February 9, 2011 Damn ... should not have said the above ... :-/ Quickly tested this new 2600K: 5150MHz seems to be the max L046B632 #0368 Quote
Splave Posted February 9, 2011 Posted February 9, 2011 (edited) ^pwnd L045a912s 2417 = 5600mhz max normal air L045a912's 2616 = 5287 max 32m 5300 max cpuz Edited February 9, 2011 by Splave Quote
SteveRo Posted February 9, 2011 Posted February 9, 2011 Alright Mr. Splave 5600! Mr. Massman - oh well, when do you get the next one? Quote
S_A_V Posted February 9, 2011 Posted February 9, 2011 The same L039B461 #0316 as posted above, but board was changed to Asus Maximus IV Extreme. Max CPUZ on air = 5311 MHz 1.6V Max CPUZ on LN2 = 5362 MHz 1.7V, 5329 MHz wPrime 1024M Clock scaling from temperature: +30C to -80C = +50 MHz! Quote
Splave Posted February 9, 2011 Posted February 9, 2011 massman please edit my last post I swapped serials accidentall. I fixed it in the post (MM) //edit: editing your last post. Okay now? Quote
Linuxfan Posted February 11, 2011 Posted February 11, 2011 Are you guys booting at max freq. on the Asus boards with your 5ghz+ chips or changing in OS with something? I've been booting max freq. Reporting two new chips tested on air: L045A912 #0490: Doesn't boot over 1.5vcore, 50x multi barely stable to boot into windows so 5005mhz max freq. Wasn't stable and doesn't work with more volts or less volts. 51x, 52x, and 53x nope. Booted at 4c8t and 4c4t no difference both unstable. L046B106 #2331 Max multi bootable: 52x Max bclk: 100.5 Max MHZ: 5227 at 1.62v, not lower vcore or doesn't boot. Stableish on air, not Wprime stable though. 4c8t. Quote
Linuxfan Posted February 12, 2011 Posted February 12, 2011 L045A912 #3054 5100mhz max 51X didn't work with 101bclk Quote
hoss331 Posted February 12, 2011 Posted February 12, 2011 L040B705 #2210 max 52x L046B106 #2212 max 51x L045A912 #2239 max 57x L045A912 #0002 max 51x Quote
Massman Posted February 12, 2011 Author Posted February 12, 2011 Thanks for the input guys! Are you guys booting at max freq. on the Asus boards with your 5ghz+ chips or changing in OS with something?I've been booting max freq. 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. Quote
eva2000 Posted February 12, 2011 Posted February 12, 2011 wow with amount of 51x max multi cpus, i have to count myself lucky maxing at 52x but that's it for my 2600K L038A660 - 5ghz 1.38v but 5.2ghz max 32M pi http://i4memory.com/blogs/eva2000/46-intel-core-i7-2600k-l038a660-gigabyte-p67a-ud7.html Quote
MAGARAC Posted February 12, 2011 Posted February 12, 2011 (edited) I tested my 2600k under DICE and same 5290 max like on air. Tryed my luck with another chip and I wasnt lucky at all x51 max. http://hwbot.org/community/submission/2123393_magarac_wprime_1024m_core_i7_2600k_2min_24sec_468ms At least I finished wprime1024 and 2133 finaly works, but not cl8.

For example most of my chips can get to the windows load screen at 55x+ turbo multi but they can't actually get past the windows loading page into the desktop. Testing on SS now and tested high volts, doesn't help me get higher and none of these chips is going to actually finish booting 55x+. Quote

Massman Posted February 14, 2011 Author Posted February 14, 2011 Thanks Oanvoanc! Batch L051B863 looks quite promising. Although this is just one result, that first result being 5.5G is reason enough to try other samples of that batch. Quote
hokiealumnus Posted February 14, 2011 Posted February 14, 2011 (edited) Better late than never I suppose. Retail 2600K, Batch # L042A969 on an ASRock P67 Extreme 6 LinX stable @ 4.6 GHz / 1.256Vcore loaded ...................4.8 GHz / 1.344Vcore loaded CPUZ @ 5519 SP1M @ 5519 - 6.771s WP32M @ 5447 - 4.679s Vantage @ 5418 3DMark06 @ 5418 It also ran 01 & 03 there. 01 result was disappointing of course because Gigabyte seems to have the market on those results. Vcore for all of that was around 1.6'ish loaded. It was 1.584 idle but LLC was on full, so it boosted a hair under load. Cooling was this classy looking water loop (board & RAM changed for the results above): [ATTACH]914[/ATTACH] That was one evening of benching. Couldn't get it to boot at 56x. Yet. Rest assured I'll try when time allows. Haven't even tried BCLK adjustments yet. Lots of toying around to be had, but this should be enough for another batch data point.
