Purchased two intel i7 4790k Processor

[rsp]

Hi ,

i have purchased two intel i7 4790k processor 1 month back but i just found that they both have the same S/N: and Batch#: and everything is same to same , is it original product ?

sorry for asking silly questions like this but i'am really worried if it is original or not , i hope you understand , thanks !

 

[Yuriman]

I'm not sure I understand. Who else could make a 4790k? They both work, right?

 

[rsp]

yes , they both working fine , but i need to know does intel make like this , they both have the same warranty period

Looks like you have got a cheap Chinese copy, I would be very cautious about using them in a production box. You never know, what kind of backdoor they may have put in place there :awe:

See.

:hmm:
i have purchased from local store and i got the bill also but in that bill they did not entered serial #
it make sense now , is there any way to claim original product

I've never heard of a fake and functional i7. OP, why do you think it is a fake?

 

[VirtualLarry]

"overruns" from a "factory lot" in China? Of course, one would think Intel would have controls over these things.

Maybe they were packaging defective dice after-hours, and selling them on the grey market? (Edit: This happens with NAND and DRAM, so I hear. CPUs wouldn't be totally unheard of.)

:'(

because i have the same serial # and batch #

 

[videogames101]

if they work, i don't see the issue, no one else has the fabs/designs to make one except intel so it pretty much can't be fake if it works

How about some pics of the fake cpus.

 

[lyssword]

run it thru cpu benchmark or something. I mean it's not like you can just "copy" a cpu like you can a watch or a purse, if it runs like i7/same cores and threads it can only be i7. Unless it was replaced with lower level intel cpu.
Only possible reasons for fake serial numbers:
1. Cpus were stolen from some computer shops or pulled from computers (used?)
2.replaced with cheaper dual core version (but same socket)

 

[Elixer]

They could be real intel chips, but, not what they say they are.
Use CPU-Z or something along those lines, and see if it really is really a i7, and not a i3 or i5.
I would also request some pics to see what you are seeing...

Where do you see serial#? Is it on the box itself?

Well, if it passes CPU stability tests w/ AVX2 workloads (Prime95/LinX/IBT), I wouldn't worry about it. Also, you could give Intel a call for further clarifications. Can't comment on packaging.

 

[ShintaiDK]

Same batch number is perfectly fine.

Can you make a picture of both?

 

[Burpo]

Exactly, serial numbers are on the box. Batch numbers are on the CPU. Same batch isn't uncommon.

 

[hawtdawg]

engineering samples?

 

[schmuckley]

pics or close thread

Serial number is printed on the CPU also, right? Does that matches with that on the box?

I don't believe that the serial number is laser-etched onto the CPU's heatspreader, only the batch number. I believe that Intel has internal tools to read the CPU's serial number out of the CPU's PI-ROM area using debug tools.

There are 2 serial numbers,one on IHS,one on PCB.Usually there's a qr-code as well.
See right side of this one

 

[StinkyPinky]

I'm pretty sure some grubby Chinese factory doesn't have the skill and expertise to do knock off i7 cpu's. If they do, someone hire them pronto. Clearly they are geniuses.

 

[ShintaiDK]

The IHS one is a batch number. And the one on the side is an UPC number.

Interesting. Don't you need that for warranty purposes?

Correct, neither are serial numbers..
