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

[jcniest5]

I never had one that could not hit 5ghz all of them have booted 50x and higher. . .

It's funny that some people never get anything that can't do 5Ghz or above while others only get those that only do 4.9Ghz and under.

[Dumo]

On air, PLL enabled and Vcore+ most will do 5Ghz windows bootable...when added those stressful tests then stability needs more tweaking for some

When I say 5Ghz or 4.9Ghz, I'm hoping it's not just "bootable," but also "stable." Bootable doesn't mean much to me.

Is there a 2500/2600K that cant do 4.5Ghz, it seems that everyone is hitting 4.5Ghz as a minimum from what I've seen jumping around the previous pages.

my 2600k cant do 4.5ghz without voltage past 1.378 and i'm not going to do it . the chip isnt the best and i am done with it. if i see someone list a better one for sale i will i will buy it and resale this one

Or just give him a decent death and RMA it for good

I see, since ill be getting 2x 2600K's I might as well really test out both which does 4.5Ghz at the lowest possible voltage.

I'll be learning SB overclocking at the same time, can anyone give me some quick tips so I can sort out which chip to keep ?

Intel has a way of telling if the voltage was extreme before it pops, so doing that isn't good. Just sell it and say it's not a good OCer, but runs perfect at stock. Most people don't really OC, so if the price is right, someone will buy it.

lol that's good stuff, I have seen so many deaths/degradation/etc. . . and intel always RMA's as long as there is no physical damage, i.e. heat spreader removed

that is how i would sell it , if i find a better one or someone offers one for sale i will then sell this one.

Be honest about why you are selling it, price it $20.00 - $30.00 under retail along with free shipping and you can sell them as fast as you can list them. I have moved more 2600K processors like this then I care to admit. LOL.

Intel never refused my RMA's... E8600 with burned contacts due to condensation on xtreme cooling, Q6600 , i940, i920 , x6800 all dead by condesation. All the RMA's went well and within 15days, so I don't know where did you got that idea...

I earned an i5 2500K these days and played a little but with it.
Unfortunately my chip were extremly hot.
At 4,5GHz under prime load CoreTemp showed me 72°C with all voltages untouched just raised the multiplier.
72°C was pretty hot i thought cause i used a Prolimatech Super Mega to cool that thing down.

I heard some rumors that maybe some of the heatspreaders on Sandy are not properly attached to the die. Can you confirm anything like that?
Anyway i wanna buy a new one cause i would like to go for 4,5GHz with good temperatures which shouldn`t be such a big deal.

Are there any specific batches which you guys can recommend or it it just totally random what you get?

[C-N]

SB heatspreader ihs is soldered onto core

[KingZer0]

So you would say the rumors are not true about some rather hot sandys due to not properly soldered heatspreader?

I compared my results to many other guys out there on air cooling but something seemed just wrong. Thermal paste was Prolimatech PK-1.

Batch# 3049A423 Costa Rica 2600K
5.0GHz @ 1.44v set in bios 75% LLC

Finally very happy after 6 cpus...

[Asmola]

I tried to find lowest voltage for 5GHz which will pass 5 rounds Linx with AVX..
Damn that stresses CPU a lot, stress voltage is 1.42v. Without AVX temps would be about 10c lower! :O

What's your vcore at stress load at 4.5 ghz?

What's the BIOS default "VID", back at 3.4 ghz? (What does the BIOS report the target voltage as?) The VID is not the voltage you set it at OR the voltage in health monitoring (that's the currently set vcore after vdroop)--it's the voltage the BIOS would set if you had it at auto.

When I say 5Ghz or 4.9Ghz, I'm hoping it's not just "bootable," but also "stable." Bootable doesn't mean much to me.

Then the better the cooling, the stable it will

I did not test for 5ghz stability on every chip but most can do it with around 1.42-1.48 cpuz volts, so probably 1.45-1.50 in the bios, unless you have a really bad one, and your cooling is not up to par.

my worst 2500k did 4.7 prime/linx stable at 1.36 and it was just a very hot chip for air

Ain't bad Mine can do 21 runs with 1.376v load :p

There are really bad chips out there :s

Cooling?

Edit: I already find that you have water cooling.. i wish i could try this one with water also!

We also have almost same batch#, i have L042B074. This one works well with x56, max is somewhere near 5,65 with aircooling.

[st0ned]

Verry nice indeed, I can boot with 56x without blinking but it always crashes when entering windows... even with LN2

Need significantly more Vcore than Costarica in general

Rest in Auto.
