Hi i just recently got an E6600 but i have been reading up on the coding on the chip. Mine says L630A now this would be week 30 (eg: 24/7 ) but what is the A? I have seen chips with L630B. what is the difference? should i be worried? Im not really planing to o/c it into h.. , but i will try to reach 3ghz. Should i get a new one? Is there even any realworld difference? what about stabillity? And Heat? i think i read somewhere that the A version uses more power, is this correct?
what is the number at the bottom of your chip? mine says L630A and then some numbers i cant figure out. The L6 im unsure about, so far all the Core2duo chips i have seen have the number.L6, then followed by the week number (min is week 30 eg. l630a). The stepping as far as i can figure must be the A orB, but im very unsure. Read my first post.
It is too much of a hassle to pull off my heatsink to check the chip. But apparently my retail box has the details... FPO/BATCH# is listed at L632A163... I have no idea what the A means (or the rest of it), but apparently I'm week 32.
I will wait for JumpingJack or someone more knowledgeable to answer your question thoroughly but I can answer it by saying the difference is very small in regards to heat output, if any is notable. Overclocking is occasionally different when steppings change, but I haven't heard anything about Core 2's changing much so don't worry about it. Definitely not worth exchanging for a new one.
Yea I wouldnt worry to much, there are a few different versions of my chip and most people say that the version I have only gets up to around 2.4 - 2.5ghz and I have had mine to 2.62 stable I just dont like to use voltage above 1.4v, so I lowered it to 2.55ghz and used a pretty low voltage for the OC on this chip and kept my temps lower so I could still use the side panel on my case. I think you will be ok to reach 3ghz!
I don't know your answer, but my chip maxes out at 3400 mhz. I have read alot of other articles, and started forums on getting it up to 3600 mhz. The responses I have been given are that most people can't run it stable over 3500mhz at any voltage levels.
Realistically I think you can expect to get 3400 mhz out of it. Even www.anandtech.com didn't push theirs past 3500mhz.
If you really want to get 4 ghz I have seen x6800s reach it more easily. Although this will probably blow your budget.
The good news is my 3400mhz runs a super pi 1m in just 17 seconds, so that is very good.
