Newer batches of Conroe OCing poorly?

**CedricFP** · 03-21-2007, 09:48 PM

I recently saw a few threads where people have mentioned this observation...

But I can't see any reasoning for it. Are Intel binning their chips higher, so E6600's no longer have that much OC potential? Is that being saved for E6700 or X6800's?

Or are they simply using cheaper (or worse) materials (silicon?) because of the huge headroom in the first 30 or so weeks?

I ordered a Xeon 3070 it'll be here friday so we'll find out.

edit: as a side note I had to use 1.55000 volts to get 3.3Ghz with my week 42A.

ur talking about E6600 right?

Generally speaking Conroe has had a huge scaling potential above the rated speeds. Intel ofcourse doesn't get paid for huge OCs but the amount of sold chips. They could've tweaked the fab process to favor yields instead of scaling.

yes the one in my sig "6600 L642A289".

I posted it in the oc database if anyone cares.

WOW 1.55? I was thinking of selling my E6400 that will do 3.2ghz @ 1.35-1.375 now im reconsider keeping it.

**CedricFP** · 03-22-2007, 12:16 AM

I just bought a E6600 week 27B than can do 3.8 @ 1.42 orthos stable on Air... it's a much earlier week than the ones that can be bought now, and seems to overclock better as well.

The yield idea makes sense. It's a real shame for OCers, though.

**Rickster_64** · 03-22-2007, 06:13 AM

I also debated on buying a 6600, but if this is true I will hold onto what I have.

**Stelios** · 03-22-2007, 06:38 AM

I saw an E6600 L707Axxx here in Hellas ... I'll try to test it .

**Skyline GT-R** · 03-22-2007, 06:50 AM

I think the answer is pretty simple, Q6600. They need the better chips for there quad core's.

and i thought me having to go to 1.475v for 3.3 was bad....

voltage needed seem to increase exponentionally as i increase fsb...

**ahmad** · 03-22-2007, 07:03 AM

And we don't have anything that can OC quads properly...

**fhpchris** · 03-22-2007, 07:29 AM

uh, the EVGA 680i and the P5B Dlx work perfectly with the quads

**Rickster_64** · 03-22-2007, 07:55 AM

I need to dig out my exact batch but its week 32 from what I remember, and I am stable @ 3300 with 1.3V. Factory Intel cooling. Sounds cheesey but sometimes I read reviews on newegg.com as people post results from recent purchases you have another source for how the newer cores are clocking.

**uOpt** · 03-22-2007, 08:20 AM

I believe that they reserve the best dies for the quad-cores.

Since they have to put two dies into one CPU case it is very important for them to do so at the lowest voltage and heat, which basically means the best clocking dies.

Now, if you would buy a QX6700 and made two Conroes from it...

**NaeKuh** · 03-22-2007, 10:43 AM

fry's has a few more 31B batches at the burbank store CA. The manager was nice enough to let me hand pick mine out of his supply after a quick non flat ihs proof.

As of friday, when i went, i saw a total of 8 oem 31B batches.

Mine DID (b4 bios flash) 3.6ghz on 1.387 Its having problems at stock after the bios flash.

But if anyone is interested, id hurry and pick one up if your still looking and in the area.

Should warn you guys tho, she runs a bit hot compared to all the other C2D's ive seen. Definitely a lot hotter then the A batch, and even some anandales.

**Barnsley-Bill** · 03-22-2007, 11:32 AM

I.ll have to dig my box out and see what my e6600 is ive got it runing at 3.7~ 1.56v my QX6700 should come sometime this week then i.ll try that

.

**ownage** · 03-22-2007, 11:39 AM

newer batches are b!tches, :P
They just dont clock, i've seen xtreme users who only could hit 3,2ghz with xeon 30**, and way to much volts.
I'm glad my week25 clocks good :P
i believe they last good batches are week 31, maybe 32.

**EZClock** · 03-22-2007, 12:03 PM

My E6700 only does 3.7ghz @ 1.54v orthos. It's week 29

.

**oqvist** · 03-22-2007, 12:37 PM

What week would you estimate an E6600 I am buying that is sixth month old is?

**mag|c** · 03-22-2007, 02:02 PM

I found out my DELL has a 629B E6400 (witch is suppose to be quite ok) - and the P965 board inside has ZERO oc options, gee that suck bigtime!

**ziddey** · 03-22-2007, 02:29 PM

hmm if there's a bios revision for the board that gains support for 1333fsb e0 conroes, then you could try modding your chip to run at 2.66ghz

& the QuadGT with the B06 "R" modded BIOS.

Try to sell that to someone, the B's are nice

or buy a new computer, swap in a crappier processor, and sell the pile of lard that goes by the name of "Dell"
