Has my brand new, boxed 10900k been binned?

Hi All,

I finally got my hands on I9 10900k from a reputable European retailer (Proshop). Unfortunately, one of the seals on the box is detached. Also, there are only two seals on the outer box, nothing inside like there used to be on 9900k.

Also, there are rectangular marks on the heat spreader - please see the attached photos. In reality they are darker and more prominent. Initially, I thought it was a thermal compound but they can't easily be removed.

Do you think this CPU was binned and tested without locking the socket with just a heat sink placed on top of it? Does anyone with a 10900k remember what their cpu looked like?

I would have said 'yes, it had been used before it was sold to me' BUT:

1. I recall the seals on my 9900k and 9900ks were really poor and came off easily.
2. Both 9900k and 9900ks had similar light, rectangular marks on the heat spreader. I believe I have read somewhere that this is the result of a manufacturing process - marks left by a kind of a suction cup that transports CPUs on the assembly line.

Yet, on this particular CPU, the marks are really visible, so I have doubts.

I also took a photo of the pin pads, I believe you can also tell from these if the CPU has been tampered with, though I don't know what I should be looking at.

Can someone please help and share their thoughts? I do not fancy returning the CPU and then waiting weeks or months for another one.

Thanks a lot in advance!

Marks are from the chip/IHS being tested by Intel before being packaged. Been discussed for years.
Now if you had thermal paste residue on it....that's a different story.

Hi Falkentyne,

Thank you for the quick reply, as always. I must have remembered the reasons for the marks on the ihs incorrectly then. It seems the CPU is ok since my 9th gen cpus had flimsy seals too...

Thanks!

The seals are pretty bad. I ordered two 10900k's the day the 2nd batch came to Sweden and both had loose seals. Same markings too. Pictures of loose seals:

Thank you for confirming! Exactly. It defeats the whole purpose of using these seals when they come off by themselves.

I've had 2 10900K from Newegg and neither had the flimsy seal nor any markings on the CPU. My 3rd 10900K came from OC UK before the price hike and it had the exact same marking on the CPU that could not be removed even with Isopropyl and the seal was flimsy on both sides with one actually detached when I pulled it out of the shipment box. OC UK is a very reputable company, but it still left me with a feeling that the CPU could have been possibly opened, tested without clamping and then repackaging. While this likely didn't happen, it would be nice if Intel would do a better job packaging their products to ensure tamper proof factory seals.

This is even more of a concern with Asus new SP # being somewhat accurate indicator of overall silicon quality. You could easily open it, put the CPU into the bracket and just enough pressure ontop from a heastink to check the SP to bin it and then either keep or repackage it.

If Intel is testing CPUs before packaging, I wonder why some have the marks on the IHS and others don't. Different QC lines?

Also, I am now pretty sure that my CPU has been used, so probably binned. I looked at the photos I took before putting the CPU in the socket and now I can see that there are small indentations on the pin pads where the pins made contact with them - see attached.

I assume this means it must have been used? Or could these be from the Intel factory testing and can be present on a brand new CPU?

Yes they can be present on a new CPU. They have to be tested somehow to make sure all voltages, ground, DDR and PCIE are in spec. How else would you test them?
I'm almost 100% sure either my 2600k or QX9650 had marks like this.

testing is partially done by hand no? probably variation on how someone mounts

@Falkentyne and TK421.
Thank you for the replies. This makes sense.
