Is my Conroe a good stepping?

[Pulsedriver]

Hey folks,

So as I am in the process of changing my motherboard etc etc I thought i'd have a look at my E6600 Conroe for the stepping code;

6600 SL958 MALAY
2.4GHZ / 4M / 1 866 /06
L624 A604


Is there such a thing as a good & bad batch of steppings for these Conroes?

L624A sounds familiar, think i did one for a client o'ced at 3.2Ghz 1.45v, mediocre, but not a bad core and mine could just be a bad sample.

Yep same here had a l624a and it could only reach3.33ghz satble @1.45 after that would not be 8 hours Orthos stable however much vcore! Got myself a nice L644g380 now that is happy @3.6 1.45v and much lower temps!

just out of curiocity... mine is L644G278

that any good? not overclocked it yet

 

[Rroff]

Best ones are weeks 26 through to 29 really... 26 are hit and miss some good some bad, 27 has mostly good, 28 is almost all good and 29 are mostly average but theres some stunning week 29 chips I know of one E6600 from that week that does 3.6gig on stock vcore and 4gig at 1.55v.

am i 27?

(i am in age)

 

[Buckster]

nope - bad week I'm afraid

3.3 best I can do with 1.51V ...

currently at 3.25 @ 1.5V (before Vdroop)

i'm a bad week? how can you tell which week?

it's in a shuttle so i probably can't overclock that much anyway

is it very bad?

 

[Buckster]

about the worst I've seen for 6600s .. I've been very frustrated with mine ...

if you want to overclock in your shuttle then I'd sell it and get another ...

you'll get up to about 2.9 gig with not too much of a Vcore rise -but after that if you want higher you'll need a fair amount of Vcore

more Vcore = more heat = not ideal for a shuttle

depends on what you want with it.

I'd change mine if it wasn't for all the faff ...

Sorry if this is a nooby post, but how can the week a CPU is produced effect how much it is overclockable? I guess they make CPU's in batches, but surely each batch is the same as the last?

A different batch might have slightly different material properties that affect their maximum speed. Also as tweaks etc.. are applied to the process, it may have a negative or positive effect on the yield and speeds, for instance when they try a tweak it may actually decrease the average overclockability of the batch until they get it right. Also on the flip side, a new batch might bring about a successful tweak and thus raise the overclockability, Tbred A to Tbred B, DLT3C Tbreds, AXIA Athlon Thunderbirds etc.. are examples of this.

yeah think i'll just go upto whatever it can do with no vcore increase...

take it you have exactly the same one?

cheers

 

[Pulsedriver]

I only want to get a 3ghz overclock, so not a huge ask I guess, I hope mine can do it.

What sort of vcore and multiplier should I look to feed it then? As my BIOS is set to Vcore AUTO at the moment.

week 32a supposed to be good

I have a 32a and I can hit 4ghz and webbo is on 32a and 4ghz stable

 

[getcarter]

yeah but by the details listed on the processor itself, how can u tell what week it was produced?

 

[truebluecfc]

I guess i've got a bad batch/week whatever as mine took a lot of paitence,time and effort to get mine to 3.2GHz on 1.425. At first it didnt even what to know about 3GHz on 1.55, although i have to say my temps are quite low.
