Hello,

 

I saw your post and it seems I got the same batch number as yours. I haven't opened the box yet (brand new), still waiting to get CM N600 in the end of the week. Haven't purchased a CPU cooler yet (I'm going to buy Noctua NH-D15, the best one from this company; review #1 / review #2 / D15 club). Curious if I need to return the CPU to the store (it will take 30 days to receive the money, few hours ago have been delivered to me) and purchashing the same CPU from other store or to unpack it and use this one (with N600 and D15)?

 

tried one shop from germany and got 1 epic fail 4.7@1.2 and a 4.8@1.35v,waiting for the 3rd and last one,then i'm done.

 

It's not clear what was the first batch number, store name/country, temps/clocks and the 2nd batch number. The quoted posted above not clear if the results were for the 1st or for the 2nd.

 

Regards.

what can i tell you(my opinion if ur looking for 5ghz,but most 4790k do 4.8 without problems if interested) is to send back ur cpu,cuz L420B7xx are bad (most of them) i mean bad not reaching 5ghz,but you can be lucky and maybe is a 5 ghz but is a very small % that can be good.

yes,the results above are from my 2nd chip which is L420B765.1st chip was L331C518 and did 4.7@1.2v only, no more scaling.L means malaysia,3 means year which is 2013, 31 means week 31 from 2013.

all bought from the shop that a user posted above.

HV got high price for shipping internationally and less methods. Better choice is meinpaket.de - PP, cards, bank transfer + free shipping (to DE addresses). If you use a 'mail forwarding service' in DE (with DE address that forwards the packets to your country, IT) - then it's the best way and the cheapest. Direct order with direct international shipping from ANY DE/UK site cost sooooooo much money for the shipping.

 

Alright, will think about. The local store have a policy '15 days return in original box, unpacked, no question asked'.

 

Don't forget about this comparison site. Hope it helps and saves ALOT.

already know that site for comparison.12 euro still cheaper than 15 euro here in italy and they need 3/4 days before shipping.on german site bought my mobo at 4 pm and at 9pm my mobo already flying to italy,this thing is priceless.

Batches matters.

 

Which is why batch number matters. Certain batches will be smaller based on demand, and because of that, overall quality will be better. That's why launch chips are usually so good.. the numbers are low, because few people buy chips right on launch day. AS time goes on, chips tend to sell in higher numbers, and overall quality is less, since they have greater demand.

 

… So generally people that are people *no matter from where* are buying "LQ" batches because of the greater demand.
