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

[Dumo]

What's your best BCLK with the 2500K \ 2600K that will boot to OS & post?

I can boot up high >105 BCLK (with UD7) sometimes after restarted from oc bench, but most of the time it will reset back to 34X and C1 @ boot up.

Imo, its not worth the headache of corrupted bios or os, just use easy tune 6...same result anyway

The point was/is where it can boot from set in bios. I'm sure if I wanted to use ASRock eXtreme Tuner from within the OS it might do even more, but that wasn't the question.

my new #L050A853 vid 1,2450

boots x49 no internal PLL and prime stable on that





x50 prime stable



x52+







cheers to all

Yep, 105.00 maxed from bios with UD7 C1 reboots...sometimes 2X or more...

Bios clock 53X105 BCLK enabled
PLL Enabled, other settings disabled
Ram performance Extreme, 7-10-7-25, CL1, I/O lat.1, all subs auto
LLC Level 2, Vcore 1.575V, Dram 1.72V
Use Easy Tune 6 in Windows




But, BCLK 100.00 bios guaranteed boot up to windows

Has anyone proven or disproven, that the best way to get to 5 ghz is to get a low vid (default 34x100 like 1.21-1.23 VID) CPU? And/or, that a low vid high temp CPU possibly responds better to voltage than a low temp CPU? (thus making it a screamer on water?). And all high VID chips (1.25+ VID @ stock speeds) should be avoided?

very nice dumo LLC2 ~ 1,6

some preliminary results from my newly built rig, havent tried higher till now, but saw a tangible effect of reducing PLL in cpu stability. (CPU PLL in this ss 1.709 in bios -from 1.832 default), with default pll had bsods in this vcore.

Anyone know if Newegg is shipping the "C" batches yet of either the 2600k or 2500k?
If not which batches are comming from the egg at this point?

thanks in advance

[Falkentyne]

Why do you want a "C" batch? They're not really any better.
What you want is a "3" series costa rica cpu
Haven't seen many results so far, but mine was doing 5 ghz at 1.404v load.

Lucky u. But i dont think that all Costa Rica are good.
Ive seen some of us tested CPU from 3 countries but still couldnt fine a good one. Again, it is pure luck.

[Falkentyne]

Kevin, I wish I could help, but I dont even know what to do
Even if I bought the CPU for you and had you pay me later, you might wind up getting the malay one instead cuz newegg will NEVER let you choose the batch I buy from newegg cuz I get my things next day from UPS ground, since I only live about 20 miles from their warehouse....

And didn't Tankguys turn sour and go under? I remember back during the core 2 days, tankguys was all the rage...

And Mwave...I could catch a bus to Mwave (When I lived in Walnut, which is actually 1 city away from here, I could walk to Mwave in 10 minutes or bike there in 2 minutes), but I'm afraid of the dirty look they will give me if I say "i want to buy a costa rica i7-2600k. And me being black doesn't help one bit, if you're in an asian owned store...

[l0ud_sil3nc3]

really the only way to get a batch is to go to b&m store and pick through them yourself, or buy a known good clocker from online that has been tested. Sure you usually pay a bit more for a 5.5+ but usually the chances of finding one that good or better require quite a bit of binning.

[Dumo]

@ Falkentyne...Its pure luck Fal, even peeps that have an access to bin 100s of 2600K will be lucky to find a single 57X chip.

I try to avoid being near local Micro Center, because I can't resist to gamble and buy another 2600K.......Then look stupid watching it stuck at cursor at 56X

man I know the feeling I haven't even sampled nearly as many as you and I realize how hard it is to even find one that does 56x I bet the odds of winning the lottery are better than the possibility of finding a chip that benches at >59x

Yep, Its like buying a book of $5 scratch ticket...From 250 tickets theres a lot of $1 and $2 winning, but rarely a Jackpot $25000 ticket

I'm sorry, but those curves and that bun are more enticing than that screenshot.

what's the best batch for an i7 2600k? I kinda want to upgrade to an i7 lol

it is a problem no doubt, the closest one to me is about 3 hours away and I still run out there with a few friends when ever I sell a so so chip and grab as many as I can hoping for the one.

Anyone have luck with offset mode? Even though I got the vcore where I wanted to it would occasionally lock up when changing speeds. I get insane idle wattage off of that. Even with a decent video card it clocked about 75W 4.2Ghz 1.25v on my killowatt. After testing with static vcore though its stable at this

P8P67
2600K @ 4.4Ghz 1.25v
Hyper 212+
maxes out at about 75C under prime
L050A853

This will idle at about 100W. Still pretty good It will go higher but then the temps get close to or over 80C.

[jeremyshaw]

yay, I now have an ASUS P8P67-M Pro with an i7 2600k and a Gigabyte P67 UD3 with an i5 2500k :p

[cory1234]

Don't place all your chips on the C batch. I picked up my 4th i5 2500k on vacation near a Microcenter and grabbed the only C batch they had.

Unfortunately it is just average at best. 12 hours Prime95 stable for 4.6ghz is 1.36v.
