Intel Core2Duo E6700 L626B092 = 4440MHz validation on water

Intel Core2Duo E6700 L626B092 = 4440MHz validation on water >> 5.4GHz Cascade

hey guys

we always have these discussions with Chainy that good batch# don't mean anything. Here is why i disagree

Hardware Used:
Intel Core2Duo E6700 (Batch#L626B092)
Asus P5B Deluxe WIFI (1101 bios)
2GB PC10000 Corsair Dominators
Corsair Nautilus 500 Watercooler
ATi X800 GFX Card
535W Enermax PSU

Ambients around 22-23C


I am putting it on my phase change cooler soon....just waiting for MSI P35 mobo and some DDR3 sticks to show


yeap that's right 4.3GHz ~1.57Vcore

3.6GHz 1.31VCORE REAL
1 Hour Orthos Blend Priority=8 Stable



3.9GHz 1.49VCORE REAL
PCMARK05 Stable (i did a 4GHz run with 1.53v but it crashed around the 85% mark >> need better ambients or cooling heh)





4GHz 1.47VCORE REAL

HERE IS ANOTHER 4GHz 32M SuperPI run with only 1.47VCORE with 4:5 RAM RATIO

That's good, but don't you need another CPU from the same batch to test before you can say the batch has anything to do with it

 

hahahah you sure do

you need 100x of results

thank God for XS hehhehe



update here


UPDATE!!!!

ok so i had some lower ambients ~9C lower in fact ~13-14C ambient


4440MHz Validation with 1.63v

4GHz SuperPI Testing with 600MHz 4-4-4-x 2.4v on Corsair PC10000 Dominators

1M - 12.516s





32M time no tweaks




32M time and slightly tighter timings




THERE IS A LOT OF GAIN FROM TWEAKING THE RAM.............i didn't even use wazza or any of the tweaks yet and just from RAM tweaking i feel i could go sub 12m but i need more vdimm


4150MHz 32M SuperPI >>> no RAM dividers to make it quick yet





4210MHz 1M SuperPI




4224MHz 1M SuperPI





4021MHz wPrime 1024M




4107MHz wPrime 32M




I REALISED AT THE END OF THE BENCHING SESSION THAT I HAD A MASSIVE KINK IN THE TUBING

FARK >>>

HERE IS WHAT IT LOOKED LIKE AFTER i STRAIGHTENED IT UP

 

so does that mean all L6's are good or just the E6600's?

got a L6 E6320 sitting here that's all

Its going to get the crap clocked out of it when my dam VC arrives

edit, though i'm being sarcastic, i also do not beleive in the hole this batch is better then the other thing. But still, maybe i will be proving wrong...

 

L626B

week 26
B

that normally tells part of the story and gives you an indication

week 28 B were very good also L628B121 steppings were similar to mine but finding a good E6700 is extremely difficult

 

My X6800 is L626A......clocks like craaaaaaap

 

outch
guess As and Bs are different beasts

but i've seen some nice ones with extreme cooling

Rodneys E6600 is nice which is L626A

 

my E6320 is: L636F... i shall see what she does soon

 

i don't know about L636F but i have an E6600 L629F122 which i also benchmarked at 4Ghz 32M SuperPI with 1.62v

 

Anyone had any experiences with L629B079 ? Thats what my 6700 is but it doesn't seem to want to go over 3gig... I think its the mobo tho (P5W-DH Deluxe) as its doing very weird things like loosing my sata drives and I physically have to unplug and plug them in again to work

 

I just got a L649G976 E6700 today, wonder how thats going to fare

 

4.3G Core 2 Duo processor is just CRAZY!

very impressive.

 

eva2000 has a similar one

 

Very nice chip there Dinos

Finally all that hunting has paid off

 

sure has
best one i tested to date

 

finally a gem dinos! get cracking at some hwbot benchmarks

yeah got a E6700 L629B079 tops out at 3900mhz for super pi 32m http://i4memory.com/showthread.php?t=3938

 

Right, it means nothing. He would need a few hundred samples form one batch and then he would need to calculate the standard deviation of the oc headroom.

I stay with my long standing statement which is based on more than 10 years of testing CPUs. The random differences within a batch or a lot can be bigger or as big as between batches. I have never denied though that there are differences between batches as such. My point is: You have massive differences even within a batch and nobody should waste too much time to look for a "certain" batch that few "enthusiasts" are talking up based on their "experience" with 1, 2, or maybe 4 samples.

It's a totally different story though, if we know by the manifcaturer's documentation that "errata" have been fixed or a new stepping is implemented with a new "batch".

Nice E6700 by the way.

 

if that is your opinion than we think the same pretty much

 

While there are differences even in the same batch.. wouldn't you still choose based on batch if there's a probability that on average it will be better than another batch ?

i.e. if 50 people got E6600 L629Fxxx and 50 people got E6600 L628Bxxx

And the L629Fxxx folks on average reported 3400-3600mhz needing 1.6+ vcore but some did 3900+mhz at 1.7+ vcore.

And the L628Bxxx folks on average reported 3600mhz at 1.3-1.35v vcore will some doing 4050-4100mhz at 1.6v vcore.

Yes there are more than 50 folks worldwide for these 2 batches reporting similar trends

Chainy, if you walked into a shop and had a choice of L629Fxxx and L628Bxxx which would you choose ? Now be honest

What if those 100 people all bought from the same distributor source in their area/country as well ? which batch would you choose ?

 

But didn't you come to your consensus earlier with your Q647A E4400's based on just two samples from the same batch?
