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

[aussie-revhead]

Look at the tables and that doesnt seem so, the good ones are spread all over the place with plenty of below average ones filling the gaps, there doesnt seem to be a pattern at all.

[LagunaX]

I guess there are more duds being posted lately...

[dnottis]

4.8 @ 1.34 volts only made 14 passes tho then blue screened more vcore for sure.

Mine passed linx, prime at 1.34 @ 4.8Ghz too. Needs 1.36v to be completely stable and game stable though.

[aussie-revhead]

Are any of these worth trying?

My 2500K: S/N = 2L040507A4526, Batch # L042B291

Quick test of Cinebench 11.5 at core speed 5.3GHz. RAM not tweaked

Your CPU seems to throttle.
@5.3GHz, my score is more 10.20-10.30.
Use Thermal Monitor and check if the frequency doesn't fluctuate.

edit : Sorry amdsempron, I didn't see that's a 2500K. Apologizes

10.20-10.30 are nice scores. Maybe 2600K is my next CPU

Even with batch(s) that people have had some luck and have posted decent results... strong clocking chips appear to be very random. There are some L050Axxx available here locally and I'm now considering an A batch since I've already tried/tested both B and C batch(s). I more or less have resigned myself to expect that most new samples will most likely fall into the average catagory.

A friend of mine has an L050A 2500K it runs a bit hotter than my chip but runs 5G @ 1.404 CPU-Z load & max is 55x 101 = 5555MHz 1.58v

[Sniper]

For most of use that are hunting for the golden one, it costs money. Woldnt it have been better if Intel made a new produkt 2600KX or something with only the highest binned 2600K - with a guaranteed mp of 56 or higher ?

[cstkl1]

still cheaper than what most of us spend looking for E8600

[Quad-Damage]

Whats up Quad. More vcore no doubt. How do you like the P8P67 and what ram are you running?

ADATA 1600mhz DDR 3 works ok it's 8 GB very cool and runs at 1.55 I have it set to 1.56 to boot at 1600mhz

What's the point of using these programs if they are less reliable in testing stability than just running a game?

I'm about to build my system...2600K, Asus P8P67 Deluxe, 8 GB GSkill RipJaws, Noctua DH-14 and Crucial C300 128 GB.

So what should I use to test stability?

Everything!!! I still find value running Prime and IBT but its strange to need more volts for games than stress testing software.

[zoob]

It could be due to the load your GPU places on the PSU/motherboard.

I had an OC 100% stable with a Q9550/P5Q/8800GTS512, but as soon as I plopped in a 4870 I had to bump my vCore up a notch to keep stability.

[Falkentyne]

Depends on temps as well.
Kinda pointless to run prime if the temps get to 90C (and thus crashes and bombs), and black ops doesn't top 65C, and runs 8 hours stable...
But that's for gamers. People who use their system for other things may need prime 8 hours small fft stable.

I only use these cpu abuse programs for extremely short time periods now, just to make sure I can actaully launch something without corrupting the OS. (except Prime Blend, which is VERY useful for making sure the memory or IMC is working properly).

[Peter949]

All my systems are 24/7 stable by 8hrs small fft then 8 hrs blend. I test them roughly by using Linx 25 passes with around 3-4gb of ram test out of 8gb.

water cooled CPU and GPU here, its not temps. Stress tests with real world usage is best indicator of true stability though.

Linx 3500mb HT off 50 runs min
Prime small FFT 12 - 12 3500mb 1 hour
then retest the same vcore with HT off. if it fails ure ht on vcore was fluked

also just test every 1.x2,1.x6,1.x0 vcore

[cstkl1]

lol i already gave up on this batches thingy.. the S/N low thing rubbish also

so far all the proc i tested does 5ghz between 1.5-1.52v

L041B739 SN 1xxx
L042B208 SN 1xxx - 2xxx (3procs)
L042B243 SN 01xx - 1xxx (3 procs)
L047A898 SN 09xx - 1xxx ( 2 Procs) - Very strong IMC on dram clocking. 2133 on way less than stock vccio
L051A7xx SN 0xxx

[Peter949]

Try getting a c batch.

[cstkl1]

Try getting a c batch.

not that easy bro.
whatever the distro gets

unless theres a trusty person here who dont mind sending me one
and i can wire the fund to him .
lol

[aussie-revhead]

Guys, same here, I emailed ocuk to ask what batches they have but he cant tell me, no actual stock on hand I guess. A few guys over here ordered from ocuk when there was no stock here and one got a L040B307 (the same batch as 1day's). Has anyone bought from OCUK lately? Do they have C batches?

i got one from ocuk and that was L040B307 and got one from local pc shop and that was l040b307 as well one needed very high core 1.65ish at 5373 and other same batch only needed 1.5 at 5387 both these went on 54 multi and roughly same max frequency and would not ebven boot at 5mhz higher even though could do all 3d tests pi etc at 5mhz lower

[aussie-revhead]

Isnt it crazy, such variation in a high-ish end (well it is sorta high end) cpu. Imagine the personal cost to experiment like this with 980x's....
