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

[flesheatinvirus]

I agree, its hit or miss without a ton of chips.

[Dumo]

Got 2 2600Ks from Micro Center..

Not bother with air, put both under SS


L038A660 (probly their old inventory) LLC2 Vcore 1.575 Bios

Max... It can boot up @ 54X 100BCLK with VPLL @ 1.9, but can't go >100BCLK






L041C108 LLC2 Vcore 1.54 Bios

Max...

Which MC did you get that C batch from? I could never find a C batch at the Twin Cities location.

[Falkentyne]

Dumo,
Can you do me a favor and tell me the default VID (at x34) for both cpu's?
I want to see if the VID relates to the voltages you are using at the max overclocks...

And another random question:
Does the lower VID chip run hotter than the higher VID chip (if the voltages are the same fixed voltage)?
(you can just test that right in the bios with both chips at 1.25v fixed).

Both 1.25V, the C needs less voltage to boot @ 56X comparo to other 56X chip. Dunno if any difference in temp. I run with ss @ -20ish C. evaporator temp.

[Falkentyne]

Ok thank you Dumo.

[little_scrapper]

I notice that everyone elses batch number starts with L040 or a similar L0 number.

The batch number on my 2500K is 3101A127

Seems weird.

[nijel]

Nothing weird. It's Costa Rica plant. Not common yet.

COSTA RICA!! HOLY JEBUS!!!

JK. Yea its from CR. I just got in all my camponents but Im so swampeded with schol I wont build for at least a weekbecause I is about to gradeate colege. I ar smrt now.

[Phaseshift]

wait which batch # is the costa rica plant?

[nijel]

3XXX instead of LXXX

[Dumo]

L045B021 53X max

L050A853 54X max

[Nugz]

See the "c" batches are better :/ hahah and the "d" will even be better whahaha

[Phaseshift]

so should we be looking for the costa rica ones?

Same batch L038A660 Here. boots to 56x. Haven't really played with the block. Just goes to confirm what you said earlier, it's random and theres no way to tell by batch.

Worst costa rica one I saw so far did 1.44 at 5 ghz.

[Phaseshift]

for those of you with the 2600k do you guys leave HT on?

[Trolle]

my HT is always on,no reason to disable it imho
my batch is L101B624
havent oc'ed yet but will do so shortly

I have 2 questions.

Would you consider 1.45-1.46 safe 24/7 volts on a H50?

and

What is a max safe PLL voltage? 1.85? is that safe?

[Leeghoofd]

Lower PLL voltage mate, I don't think you need it that high unless you are doing +5Ghze... Voltages for the CPU IF temps are good are no worry... Only thing you have to keep in back of the mind is : will the CPU and board keep up with the required power delivery ?

Seems like an overkill for the 24/7..

I keep mine at 4.5GHz, with max volt at 1.34. It peaks down and idles between 25-30C respectively. Hits under 20C during the night. Power saving features are amazing, though.

I can do 4.6GHz easily, but need tons of more voltage and seems like 100mhz isn't going to benefit anything.

[zaraza]

The reason I ask is I think my 2500k can do 5.1ghz with 1.45 - 1.46 volts. And that was with pll at 1.85, what is the pll voltage? My temps remained great. Lol I can do 4.8 at 1.38 but I want 5ghz.

[papatsonis]

Some of the L041Cxxx batch(s) have produced some nice clocking chips (even though there can be both strong and weak in each batch). Yours is the first I've seen ending with ...236 so I look forward to seeing your results.

finally the tests seem to end.. as i have multi limit 47x with PLL overvoltage disable



4000-> 1.140 5hrs 12k fft prime 26.5 all ram
4200-> 1.199 13hrs 12k fft prime 26.5 all ram
4400-> 1.248 15hrs 12k fft prime 26.5 all ram
4600-> 1.309 16hrs 12k fft prime 26.5 all ram
4700-> 1.341 3hrs and counting.. (hope to be stable at this setting)

(average voltage values taken from aida64 log file, during prime session)

the bad is i have to forget 5ghz.. with a 24/7 voltage setting
the good is as can be seen from the chart, has super linear scaling (in fact from 4200->4400 should need more vcore bump, maybe some component in core, needed a "headstart" in vcore to function properly? dunno), so hope will be bench-stable for short sessions on 5ghz (assuming it will keep linear, should need about 1.43-1.44 from the chart)

It seems I'm the unluckiest person on the OCing community. I have gone through 4 2600Ks and none of them goes past the 5Ghz stable. I can get suicidal screenshots, but that's it. It seems like almost everyone (except me) can get CPU that goes past the 5Ghz w/o even trying. That's how it goes, I'm probably the unluckiest person in the world, nothing goes right for me, including in real life, not just PC stuffs.

Lol. Same here. Seems like my chip cannot do 5Ghz.
