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

got my 2600k its a L045B021 seems new batch will take some weeks to arrive to my country so i cant test

My L041B204 will be here tomorrow, I cant wait to crank it up.

:)

My 2500k is L049A796. So far I've only tested with 1.3v and its happy to do 4.55GHz. Wouldn't be surprised if it can do that with 1.2v.

Now that I know how the B208 OCs, I wonder how the B243 can OC, if it can do it better (or worse) than my two.



The batch # is on your CPU Box. Just type it for us to see.

I'm on my vacation, will post the batch # as soon as I'm home :yepp:

Man, small last three digits usually means should be good. I always look for one with the smallest last three digits, but could never find one. Unlucky me!!!

I have same batch and mine its not good, needs 1,52V for LinX @5G. Max multi is 54x.

I hope you get a better one :up:

Guys, based on what I have had and seen most SB will not bench at 53 - so I would say -so far 54x is very good, not great but still very good.
Most that will not do 51 and 52 will not be reported here.

Im aware of that, this is the best one of 4 L041B204 (53x, 54x, 54x, 54x), my chip is not good for those looking for a low Volt 24/7 machine, but its an OK chip for benching 5400 @ 1.6V. ;)

I'm looking forward to Ivy Bridge. 16nm goodness :yepp: Hopefully those chips will hit 5GHz+ as the norm 24/7 OC :D

Oh yeah Ivy is going to rock. :up:

I think I agree... many average SB won't do x53. I was testing max multi on 3 2600K today and two would boot into windows at x52 but not x53 and my strongest 2600K to date seems only to boot into windows x54 but not x55. :(

Tested 4 2600K, max mp boot windows + bench:

3x L040B165 = 54,54,55
1x L040B690 = 50

Without "Internal PLL" they do:

48,48,50
45

Have used 56 mp on the best one, but only with HT off for now. Hopefully it will do 56 and HT with better cooling.

What does booting into Windows prove? If you'll notice most of the highest overclocks show superpi 1m and 32m runs..period. That's 7 seconds to 6 minutes of stability. Those high overclocks with no stability mean nothing. A chip that will do 5300 and run Linx for an hour and a half means a lot more than 5500 and a super pi run in my opinion.

I used to say the same thing and still think that, but theres a neverending facsanation with insane high CPU clocks.

I think it means something because so many can't do it... besides I haven't seen a SB LinX 20 pass @ x53. You need to get into windows to start testing/benching or you're stuck with the next lower multi and a bclk bump.

Pre AVX but if you give them enough juice they can do it.... on air!! if you can boot it!!!

Most peope trying to boot at 5500mhz or higher would care less about 1.5hrs linx. It all depends on what you are using your rig for. After all this is XtremeSystems, many are benchers.

Ket you mean 22nm :up:

That's right... and your chip is probably one of the few that can do x56 maybe even x57?:up:

I wish I could run my memory at CAS 7 or even 1T. The Ripjaw-X 8GB kit will do 2133+ but 9-11-9-28 isn't the best timing. I'd love to see a 7-7-7-21 4 GB stick. If it exists, it would be very expensive. The ones I have were only 200.00 for 8 GB. You would think it could do at least 1T, but no boot at 2133 at 1T. I have the Corsair 2000 8-8-8-24 4 GB kits, but in each board I have used them in, they have taken out slot 1 on a FTW3 and Classified 3. Coincedence? I don't think so.

Dumo, try 58x. I have heard it kills the CPU immediately. :)

Nono, Ket will get a 16nm edition....
By god, that boy can write useless shift in threads, its amazing, and start fcuked up threads...

LETS talk about upcoming processor generation and post faulty information while we are at it....

and for the "buhu" stability crap.... My chip is as stable 1M as Intel Burn, wprime 1024, vantage, and what ever I throw at it....
I can do that, but why on gods green earth would I waste 20 hours running LinX? It would be absolutely useless if it will do that or not.... :rolleyes:
100 min, max.... I know my cooling solution, it does not increase temperature dramatically...

I read Ivy would be 16nm from one of Intels sheets, they having problems with 16nm or something so switched?

ED- nvm, I'm thinking of Haswell/Rockwell.

AFAIK dont think so mate, I knew they had previous problems with TSMC but that was a whole different ball game, "gpu related"

Check my edit ;) I was thinking of Haswell/Rockwell, Ivy will indeedy be 22nm.
