Are you bending your alder-lake?

There's a thread on Reddit. Not a lot of people have responded, yet. But of the people whom did respond and tried this-----it didn't seem like anyone there found benefit. And a few of them lost function of some RAM slots, until they removed the washers.

My own setup is a Z690I AORUS ULTRA DDR4 ITX board. The backplate for my Corsair 280mm AIO isn't the worst I have seen. But also not close to the most sturdy. However, I happened to recently get EK's LGA 1700 kit for their AIO and it comes with a VERY substantial backplate. A few weeks ago, I happened across the second link you posted, and followed their advice with backplates. I am using EK backplate with my Corsair AIO. And I installed the backplate onto the motherboard----before socketing the CPU (As Igor's recommends). I don't know if my board or socket would have bent without this method. But Igor's lab says it can help prevent it.

After mounting the corsair AIO pump block onto the CPU----I decided it wasn't squared up enough. So removed the block, re-pasted, and re-installed it. When I removed it, I could see that contact was VERY good down the middle of the CPU IHS and into the top and bottom edges. The left and right sides is where the contact wasn't good and the paste was collected in there.

Attached is a rough representation of what it looked like. Red is area of good contact.

This is not good. I've been following this since Igor's Lab posted the original article weeks ago. So far none of the popular YouTube channels have picked up on it, but we need to change that. Once it gets traction, hopefully then we can start to get some answers.

I'd rather not bend a $300+ CPU, and I'd rather not MacGyver my $300+ motherboard.

Meh, it's just adding an extra mm at the base with four washers, not like you're soldering a pot to the RAM controller for more juice.
I just worry about hitting traces. A metal washer with even the slightest surface imperfections could cause issues down the road.

And what about the warranty?

Though it is doable to easily fix this yourself, I do not agree that this is the way to deal with it. It seems to be a fundamental problem with design/manufacturing. That should be solved and the damage it caused should be resolved by the responsible entity.

If this is confirmed, it should be properly dealt with. I will check mine this weekend, but I know when I checked it a week after I built my system, there were no issues. Though when closing the ILM lid, I did find it very hard to close compared to my previous ones, all pre socket 1700. And I have built more than a few hundred, so it does say something.

Big oof, I hope this doesn't bleed over into the laptop CPUs. You're SOL there.

You do know that laptop CPU's are soldered and do not use the ILM that is causing the issue? That means that laptop CPU's do not suffer this issue.

If anyone is worried about the traces you can always put a thin layer of clear nail polish on them for protection. I've seen tons of damaged traces from people over-tightening CPU coolers on just about every intel board gen.

My socket on n MSI Pro Z690A DDR4 was very hard to close too. In fact the Mobo and backplate bowed significantly from closing the socket with no CPU installed. I removed the 4 screws intending to add washers as suggested on Igor's, but I think I found the root cause. The 'hooks' on the south end of the socket were quite tight. As the retainer closes, the frame was binding up on two metal prongs that stick up out of the bracket right against the plastic part of the socket. This held the socket open around 10 degrees. I relaxed the fit by removing the retainer frame from it's base, and slightly bending the two hooks toward the motherboard. (I also bent the finger in the middle a bit toward the motherboard so it could still keep the frame in place on the base when the socket was opened.) The socket still applies the same force to the CPU as it should, but it no longer bends the Mobo when the socket closes since the socket frame does not hit on those two metal prongs until almost totally closed.

Are you talking about the finger as in the circle and the hooks as in the squares here?

The squares in your photo mark the fingers that protrude and are holding up the frame . When seated and locked, the frame was pretty level with the socket and PCB, so I think the fingers (in the square) are the right height. What I bent were the two 'hooks' to the left of those squares (on the same piece with the circled finger). I bent them downward (toward the motherboard) about half a mm. Next I had to tighten the finger in the circle to tighten the frame back to the base so it did not fall off when open.

Now the frame can lie almost flat against the socket (unlatched and with no CPU loaded) before it hits those fingers shown in the squares. Seemed to help a bunch as I don't get the bow on the backplate anymore.

I've noticed on the couple Z690 boards I've used that there seems to be two different manufacturers of the ILM used. Lotes and some other maker (not Foxconn) C/L ?...Lotes has always produced the better ILM's even back to the Sandy Bridge days. It appears to be the case with the new LGA 1700 also. The Lotes is machined better and doesn't have the flex that the C/L latch does. From what I can compare the Lotes also has a slightly higher 'Z Height' than the C/L and contributes less to any bending of the CPU. Also I'm using Noctua coolers with the new LGA 1700 mounting Kit with new spacers that provide the right amount of pressure on the CPU.

IgorsLab will have an updated article soon where they tested different boards and the different socket makes. The Lotes does appear to apply less pressure from what I've read, but that could vary wildly between boards since the tolerances that Intel specify are not that precise.

What a mess! I'm glad I waited to buy a Z690 board until more is known, but it kind of makes me just want to go AM4 in the end. A real shame AM5 isn't here yet.

With my Aorus Elite Ax I don't recall having to apply any more pressure than usual. I'm not too concerned about it as things are working fine, but if I decide to switch coolers or something like that I'll check then.
