    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 :D

    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

    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 :D

    hahahah you sure do

    you need 100x of results

    thank God for XS hehhehe



    update here


    UPDATE!!!!

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

    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

    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

    guess As and Bs are different beasts

    but i've seen some nice ones with extreme cooling :)

    Rodneys E6600 is nice which is L626A

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

    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 :(

    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. :D

    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 :D

    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?
