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

[PolRoger]

Batch# L040B307

5ghz 1,344v 8hours prime blend stable

Very nice! same batch as Chri$ch.

Very nice! same batch as Chri$ch.

Just put my 2600k in my UD5 about an hour ago same batch & its running Linx now at 5GHz 4/8 DDR 2133 1.33 bios 1.368 load ET6.... not fully tested & may need a tad more voltage later but for now this batch looks awesome.

damn i want sandy bridge

Stop jerking around with prime,my 2500k needs 1.336 to 5.0GHZ prime,but 1.38 to linx with avx 64-bit.Thats full stability,not prime

[SimpleTECH]

Starting to like this board after all. My only wish is if they could have implemented a divider for 2200MHz memory.

All results updated, keep them coming !!

Collecting thread is up here lads : SB FPO Batch DATA collecting thread

I'll be interested to see your thoughts once you get your SB. A 2600K I assume?

In the meantime, there are others that have noticed this:

Thanks again.

I'm actually considering 2500K, I don't really need HT. I'll be sure to post my results when I get them, but SP1 for Win7 hasn't been released yet so perhaps a lot of the Linpack problems stem from lack of AVX support. Even disregarding that, I'm fairly sure that the speed path is in the decode stage, so I think real world apps may be the best determinant of stability. Cinebench or x264 comes to mind.

Jesus, 140shy Gflops - this is ridiculous

so glad to hear you say that. I've been using cinebench to benchmark, but I'm also using Lightwave 3D 9.6 to test as well. I have a scene that used to take 20 minutes to render, now it's 15. When I'm not stable the renderer will crash my machine. I've given up on prime95, seeing as I can pass Linx using all memory and my worst case render test. I think based on what you've said, I'll add an x264 encode to the resting regimen as well.

I was saying from the beginning that something was fishy with prime95 on the Sandy Bridge.

Thanks for your input on this, I appreciate it.

I'm really starting to wonder where people are getting SP1. I heard if you were an MSDN member that you could get it, but it hasn't been rolled out to my computer yet.

The performance effect of AVX is really quite amazing, but as Anand's SNB Architecture Review says, AVX is able to take advantage of the SIMD INT units for FP ops. This effectively doubles the performance you would've seen with SSE only, as linpack is an FP-heavy load and does not use much integer math. This lines up with a lot of the LinX screenshots we've seen from other members at the same frequency with no SP1.

i7-1600K
Batch: L040B165


Highest overclock
Highest Clock: 5.5Ghz @ 1.55v in Bios with LLC Level 1
Additional info: Stable enough to run Super PI 1M and 32M, crashed on Prime 95 small FFT's after 2 minutes. My guess is it require slightly more Vcore.

24/7 100% stable overclock:
4.5Ghz with 1.265v LLC level 1
Adittional info: 9 hours Prime 95 Small FFT's stable.

i also managed to boot at every multipler from stock to 55. I have not tried to go higher due to the current uncertaintity about maximum voltages ect...

I got mine via a torrent listed on the official download page tho, can't find it right now.

I'm pretty sure I saw a microsoft link for it...I'll see if I can find it again.

That's the one i found, but it says release candidate. I thought the SP was finished?

Or is my understanding of RC wrong? i thought it meant that it was the final candidate to be reviewed before hte final realease...

I don't think it's ready for release until March. I could be wrong of course. You can sometimes have multiple release candidates, but RC says it's out of beta and pretty much done.

[drnip]

It is still RC.

[famish99]

I guess I'll wait for March before I get my SNB then lol (the fact that I get my bonus that month may have a hand in that decision as well.)

playing now with 2600k first impression stock cooler is crap just after loading the windows i have 50c-53c if i wait 10 min the temp fall back to 35 c (room temp) , now 5 pass intelburnin test gives 78c

[PolRoger]

I picked up a C batch 2500K close to Alex-Ro's chip. Mine is L041C123 and it seems to be a decent clocker. Initial testing... WPrime 1024M but I'm also posting a LinX run in the official SB FPO Batch list. TP67XE and Noctua NH-U12P with push/pull.

[OC Nub]

Looks like you got a very good chip, Congrats!!

Thanks OC Nub...

Now if I could only find a 2600K that can run similar clocks with HT.

[klataa]

Hello

My first screnn with my great chip L040B307. I have so many test to run so first linx stable 4500mhz with 1.25vcore in bios.

Nice low voltage! Just waiting till i do anymore benches sorting windows7 SP1 out for 2600k to use AVX!
