Purchased two intel i7 4790k Processor

[BonzaiDuck]

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.

The only counterfeiting episode I'm aware of took place back at turn of last decade, with Pentium 2 (266, 300, . . . 400) models. Intel, like any industrialist, wanted "product differentiation" without extra production costs. So they rolled them off the same assembly-line, after building in a feature that would allow disabling operation at a higher speed.

Then somebody in the Philippines figured out how to re-enable the "lesser processor" and make it a "greater one." But it still originated in an Intel factory.

If the Chinese could replicate the production process for a complete Intel chip, figure they've got enough information to create a "third market player" and design their own CPU. The myth that the Chinese are only successful "duplicators" of "Western technology" isn't accurate.

They're only more unscrupulous about patents and intellectual property. And even that is changing.

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

You need to keep the box and stock heatsink and warranty paperwork for an RMA, as I understand it. You can't just RMA a bare CPU.

Hmm..How many Intel RMAs have you done?

You read the number off of the PCB.

That's what I did. They only wanted the batch and ATPO/serial from me iirc. Granted it was a 3930k, but I asked and they didn't care about the box and paperwork. Pretty sure you still need the stock heatsink for the non-E chips though.

You can still get the serial off the markings of the (LGA 1150) chip itself. Just combine the 5th line printed on the IHS and the digits printed on the substrate.

Interesting, thanks for the reference.

Looks like two different chips to me.

Both chips have the same batch number. Perfectly normal. One has serial number L427C637-3397, and the other has serial number L427C637-2637 (refer to the link I posted above).

2637 looks like a used chip though, not sure if you bought it new.

EDIT: didn't see the pics with the boxes and labels, whoops. This thread needs a 56k warning or similar

Your chips appear to have been sold as "Intel China Boxed Processors" (no idea those existed nor why). That might explain why your chips have different serial numbers printed on the box stickers compared to what I posted above.

I can't find anything in the warranty pages about those having different warranties from any other retail boxed processor, so you should still have warranties for your chips. I plugged in the serial numbers printed on the box stickers, and it says (according to Google Translate)

Congratulations! You buy this processor for Intel boxed processors authentic. <Boxed genuine look and feel true core Care>

In other words, you're good to go.

Why don't you just pop the chip into a mobo and test it? Unless you bought them to resell them then surely you've got a system or two that they're going into.
