this is the second one i have had the first one was the same batch code but needed a lot of vcore but was cool running this one needs little vcore but runs warmer

hope you got a good one :)

btw what our the 2500k's max multis topping out at?

I don't know either, but you may want to check for throttling or something else.
I did a quick 1 pass test in XP, with "normal" (700mb) and I got 56 gflops, at 4 ghz at 100x40 and HT off.

You're getting less than half that at 25% higher clocks and HT on...

Pretty sure even my qx9650 was getting higher at 4g...definitely want to check...

Guys, Im up :banana::banana::banana::banana: creek, three local stores only have L051A964 so it seems to be the current batch here so what do I do? Get one? Keep looking for better? What is OCUK shipping atm?

Is that supposed to be 4.5GHz? If so you can probably use a lot less voltage than that. Try 1.25-1.28v.

My 2500k has a max multi of 63x, but getting it 110% rock solid stable above 4.65GHz takes quite a bit of voltage.. not worth the extra heat IMO.

Ket 63x multi is impossible, highest i've seen is 58x and thats on the 2600k with phase change cooling.. If anyone can reach 63x ill dress up as a girl and you can treat me like a rag doll hahaha :)

very nice PolRoger, I love low volt overclocks, it a shame these cpus vary so much within the same batches. Im looking for one now but good looking ones are hard to find.

Bad news, your Biostar is dead now that you found a great chip. :(
Did you manage to fix the 99,7 bug before it die?

I tried the batt. thing like you did, but it was still stuck @ 99.7.
I flashed back to 103.BST and board won't boot. Post code shows 0d.

I had 63x with 1.43A ( or, I think it was 1.43A. Done a lot of flashing last few days) and max multi was indeed 63x. I can show you a screen of the current 1.5 UEFI I'm using and a 60x multi though.

55x WPrime 1024M stable... but I haven't tested 56x yet... (hopefully).

Now I just need to find a matching 2600K to go with it!

How good would it be to work in a computer store right now? Quickly test every K going out - if its good you pocket it and chuck another one in ..... :rofl:

Its not guaranteed though...even with the same batch, but at least I have some base batch to look for:)

It only took a few minutes out of the box, install it and boot @ 54X. If it stuck at blinking cursor then is a no go.....boot up to windows then a good chance it will go higher multies:D

Yep, even my L04B243 S/N XXXA1174 can run 32m @58X, but it was at 99.7 BCLK though. If it can go with >100 BCLK and finished all 3Ds then probly its a real gem

I will find out soon with UD7:D

If its a no go then it will be the same like those 54X with >105 BCLK 2600s. Probly it isn't a multi wall but freq. wall (5800+ @ 100+ BCLK)

I think I'm gonna stop trying to find a golden batch for the moment. It seems like my motherboard is the culprit of not being to OC any of my 2600Ks (L040B305, L042B208 and L042B243) past the 5Ghz ceiling. It seems they all max at that speed. I will check regularly at the local MC and see if any of those golden batches that have been mentioned around here show up there. If one shows up, I might grab it. I actually want to order an Asus Maximus IV Extreme from one of the Candanian stores, but they aren't shipping to the US. I really wish they do. Maybe a Canadian friend can help me obtain one. Otherwise, I will wait until April or May when things are back to full swing again.

Do you think Intel knows which ones are the good ones and which ones arent, so they just sit back and laugh at us until we work it out?

No, I meant I'm sure they do know what batch or other spec is the good ones, and they probably have plenty of those held back too!

This Intel-batch-business is a tricky-one each time, but we are going to crack it, soon or later.
Intel has total control and a strict QA. These variation in OC-headroom is not a random one, either by die-peace or other stuff. Intel decides to tap good chips and they do it for a short while, and they know where to find it, with total control.

They seams to have changed to a new trick in this round, those rare C-batch# seams to be replacing the good B-batch# from last round.

Microcenter in Westbury NY USA...Grabbed a L041C108-1499 on Friday. Just like the L039B214-XXXX I have boots 54 out of the box at 1.48v. Only tinkered but it does the exact same thing on the Asrock Extreme6 as the L039B. 55 multi blinky cursor lol :rofl: It does (C Batch) however run 32m at 5.4 1.425v BIOS set Vdimm and vtt~.5 difference rest AUTO. The B batch takes a bit more voltage. Shame with the recall I'd love to test it on a better board/bios but that will have to wait I suppose...

Everybody who has clung to their P67 like a vice has to wait ATM. Won't see any movement on the UEFI front from any of the manufacturers until after the chinese holiday at least. We may even be left out in the cold completely until the re-launch of P67 boards :down:

At least at my local 3 Micro Centers 2600K and 2500K sale still going strong (even without any P67 mobo on the shelf)

On the week of 1/29 most of their inventory were batches L042BXXX and L050AXXX. Just last night all were L041Cs

Are they the 2600Ks or just the 2500Ks that have the *C* batch? I will be interested to get myself a *C* batch and see how it OCs comparing to the *B* I've got so far. At my location, all are still *B* and *A* batches...so far as of yesterday when I was there.

My 2600K L041C108 from MC won't go >52. 52 boots to windows @1.4V, but 53 and up is a no go. Got 53 up to 1.62V and it froze in bios. 54 can't even boot. Is it the chip, is it the board (UD7), is it me...?:brick:
Hope it's the board.
24/7 LinX AVX stable 4.7@1.32V.

And BTW this batch already have seen 58xx GHz with x59 @1.6xV somwhere else.

Interesting, so they are suddenly bringing out many C-batches out of the magic hat now?

If I may speculate a bit, Intel tend to bring out good batches whenever they want to push the marked for more sales. They did it with w3565 (If I remember the model# eight) last round. They kept some good week-48-batch# in storage for over 1 year and used it in w3565 to push new sales, in last round.
Based on these speculative logic, Intel may be trying to regain some marked that has been shattered by failing MBs. Anyways, I hope we can see more of these C-batches in action soon.

Hey guys... I just picked up a L041C108 as well... Waiting on a few parts then I'm throwing it together tomorrow night. I'll let ya know what kind of O/C results I get.

Anyone else with a L041C108?

Tried it for a couple days. Was good for 24/7 low Vcore, good temps, but x53 wall. Returned it today and got...

Returning Used Chips?

Where are you guys buying these chips where you can try them and then return them?

Yeah how does that work? No way we could do that here....

Dumo - man how the heck are you supposed to choose a good batch cpu when that happens? Keep buying/testing/selling until you bump into a good one?

:shrug:

I started to doubt that same batch of SB will perform similiar...after testing a few of them.
Then again my goal is to find one that can go high in multi and freq.....stricly for benching and not for 24/7 stability, low Vcore on air

For now all we can do is keep looking until we found one that fit our specific needs....either for raw high mhz benching power or smooth low power efficiency 24/7 kinda rig

FWIW the 2500k I bought ~3 weeks ago is C-batch, L041C119. Takes 1.54V Vcore to hit 5.2GHz (not stable).

Someone earlier posted 4.5GHz with 1.2V, this one seems nearer 4.1GHz at that Vcore. :(

At 1.2V seems okay for Linx @4.2GHz

But Prime with same settings above using less power and lower temp fails @4.1GHz.

Yes I was aware that v26.x was more stressful than the old one. I hadn't gotten around to downloading it yet on that particular setup. I'm testing 2600K but I'll put the 2500K back in and test 48x with 26.5 as a possible (lower voltage) daily o.c.

not true
it just finds small tweak errors here and there

very good for 2nd set subtimings

I thought they said last 4 of the Serial mean more than batch?
02-08-2011, 09:14 AM
emertX

Just the combination of Batch and Serial is saying a bit...
02-08-2011, 09:44 AM
Lsdmeasap

What's the key with Serial then? I see low serial give low max multi/bclk and higher serial giving low bclk/multi too within any given batch, so either way still seems like a crapshoot?

And then trying to find best batch and serial, no way without knowing what's what :cussing: And that's if there really is any what's what to it all :shrug: :hitself:

I wish Dr.Who would at least be kind enough to give us a few hints, couldn't hurt him or Intel any I wouldn't think. Anyone chat with him via PM, ask him if he'll stop by and give us some pointers :D

Many of the good chips i have seen so far have a s/n with last 4 digits in ~ 1000-1200 range. Not saying this means anything, i just noticed it.

Some German stores replied but none will post overseas, do you guys know any that will? Im trying to find a C batch since we dont seem to have them here, or not yet anyway.

I agree, any two chips can be very different in peak and manners within the same batch.
02-08-2011, 03:15 PM
PolRoger

I've made note of serial numbers when looking at different batch(s) and even for chips within the same batch it still seems to me that the o.c. results are quite random.

There has always been variation within each batch#s, but I don't think s/n plays a big role, or if it does, I don't think we can crack the code without having a big amount of data.

Absolutely, it is really not a great indicator as a batch produced from any area within the wafer can display drastically different ability. I have had same batch chips that acted very different at high speeds not to mention major load temp differences, hot and cold chips and non consistent voltage requirements at a set speed. The search for the golden chip continues.

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

Flesh,
I wonder if "hot and cold" chips have to do with the quality/solder of the IHS? (But no one has been brave enough to try removing one ever since the failures with core i7's...)

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

I've had 2x B and 2x C and C is much better for 24/7 clock needs about .05V less for same clock.

Why are most of these new batches such duds compared to the earlier batches?
This seems like Core 2 Duo and Penryn all over again...
