Hi!
@pldelisle:
Or maybe I could only add an Intel Quad port i350 board to my actual « server » for 80$ CAD on eBay? I know these are made in China… are these boards as good as the genuine ones? I saw this one
Some people say that they are, most I believe say that they are not and that the parts and design are of lesser quality.
The card you posted is definitely meant to deceive…
While the main chip is quite likely a real Intel chip (because Intel sells them to third parties), the Delta chips are clearly fake. Delta is supposed to be embossed, not printed like it is on the one you posted.
What I would try to get if I were you would be an HP, IBM or other OEM version of an I340 or I350, preferably new and hopefully from a Canadian (which I assume you are since you used an ebay.ca link) or US seller.
If the card is a real one it should look nearly identical to a real Intel card with some possible substitutions.
I have both a know real Intel I340-T4 bought full price and from a known legit place and its HP version bought off eBay…
They essentially look the same with some subtle differences.
The Delta chips on both are embossed which is a good sign.
A thread on servethehome (https://forums.servethehome.com/index.php?threads/comparison-intel-i350-t4-genuine-vs-fake.6917/) suggested some of the differences between my cards were a sign of a counterfeit card but I do not fully agree with they said. They were of course comparing I350s together and I am comparing I340s but I don't believe it makes much difference.
The clock crystal is different. The known real Intel has a TXC like servethehome said a real Intel card has but my HP version has a branded clock crystal from a known Intel supplier. I believe what is important here is to have a branded clock crystal (not a no name like the counterfeit cards) preferably from a known Intel supplier.
The inductors are also different between both card but this were things get funny…
My known real Intel card has the inductors they say are fake while my HP version of the same card has the ones they say are OK…
I don't think you should say that a card is a counterfeit solely because less important components (like the clock crystal and inductors) are different, Intel uses different suppliers for some of those parts so they are bound to be different sometimes. You should however always expect to have real embossed Delta chips and things such as clock crystals should be branded, not no name parts…
Good luck and have a nice day!
