I’ve had this happen so many times it needs to be said.
Intel, I think you make this problem mainstream and you should be smacked in the face.
AMD what in the upside down heaven were you thinking following Intel?
Here’s the beans I’m spilling: you’re both retarded for making cpu chips without pins. the cheap ass metal wears out within 1 or 2 applications and it starts losing functionality and stability.
I’ve had this ONLY happen on Intel and AMD pin-less processors.
Now I can’t even use my iGPU on my 7700x without it freezing every second, actually locks up. You wanna know why? Because the cooler is actually on straight and even and so is the motherboard.
if I loosen the top two mount screws the iGPU is solid. But my cooler is damn near falling off, wtf!?
NEVER MAKE THAT DUMB SHIT AGAIN IF YOU LOVE EARTH.
i have to say ive never had that happen. not trying to discount your experience. but if you use something like thermal grizzly’s contact frame, does the issue resolve? just things to try…
I’ve got Westmere and Cascade Lake generation Xeons with LGA, bought used, that I’ve uninstalled and reinstalled over a dozen times. All retain full functionality.
Unless Zen 4 has faulty LGA pads, this is a non-issue.
I kinda agree. If there’s a valid electrical engineering reason for it, fine (and I’d love for someone to explain it if there is), but I’ve always thought LGA makes less sense than PGA and cynical me believes the change was made in large part to offload the fragile pins and accompanying RMA costs to the motherboard manufacturers.
LGA is necessary after a certain point of technological development to drive down and get consistent pin impedance; also PGA-ZIF has inferior density to LGA. BGA improves over LGA on all of these characteristics.
One interesting thing is that PGA-ZIF sockets often aren’t rated for insertion cycles while LGA sockets always are, but even then the LGA sockets are almost always rated for atleast 20 cycles if not more.
What @twin_savage said. Also harder to drop a motherboard, less likely to bend a pin if you do, and motherboards tend to cost less than CPUs. So the offload’s not entirely one sided.
My remark about shit tier is aimed at A620, which is essentially scraps. And you wouldn’t pair a620 with the tiers listed in the table. For B650 you could make an argument, but it’s not priced that much lower than X670 and I couldn’t find a nice table.
Besides, OP posted about 7700x. Would you put it in a shit-tier motherboard?
Agreed, A620 boards are just not as good as B650 - though, to be fair, they are better than say, the A520 or A320 boards.
A620 tend to have poor cooling capabilities (which is fine if you are going to rock a $100 35W-65W TDP CPU, a lot less fine for a 9800X3D) and lack significant features, though I would still take A620 over Hx10. That said, when a decent B650 board can be had for $30 more, it rarely makes sense to get an A620 board. After all, entry level gaming PC builds start at $700 these days.
Here is a helpful table listing the capabilities of each chipset, but capability wise, the only thing you are missing out on with a higher tier chipset, are the additional PCIe 5.0 lanes and USB 4:
¹ Feature is optional, so most manufacturers will not include it
So A620 / B840 are not quite trash tier, but they are severely limited for sure. You will not really feel it is lacking much except for, maybe, USB ports and your components will run quite a bit hotter than usual.
Again though, for DIY, why settle for a C-tier when you can get A-tier for an extra $30-$50?
