New retention mechanism

1207 pins
AMD's new LGA-1207 is ready for quad-core Opterons

Although at this time, details are scarce, we are able to reveal some images of AMD's next-generation Opteron socket, called Socket F. AMD's Socket F will be a LGA-type socket with 1207 pins, and is an entirely new design from current Opteron sockets. We've read that the new socket will be used for upcoming dual-core Opterons as well as quad-core Opterons. The new socket comes with an updated retention mechanism.

Intel adopted the LGA socket design with Prescott to reduce cost and also to reduce the defect rate on processors.  After all, would you rather scrap a $600 CPU for a bent pin, or a $100 motherboard for a bent land grid?  A few days ago, we got some pictures of the upcoming Intel 771 LGA socket for Xeon motherboards.

I'd rather bend cpu pin

Am I the only one who hates the LGA Socket - from the article - "Intel adopted the LGA socket design with Prescott to reduce cost and also to reduce the defect rate on processors. After all, would you rather scrap a $600 CPU for a bent pin, or a $100 motherboard for a bent land grid?"

Umm, ok first of all, where are you buying a $100 quad-core opteron board from? These boards are going to be in servers. Let's say you go to upgrade the cpu and you bend a pin on the motherboard - then what?? That board is probably discontinued by now - so have to get a different one. You replace the board and you'll screw up Windows and if you're lucky, maybe you can rebuild. Maybe not - maybe have to format - hope this isn't an important server. Versus, you bend pin on new cpu, you just put the old back in and back up and running until you get a replacement cpu. You'll always be able to get a cpu, not a motherboard. Not to mention, how long is it going to take for you to unplug everything and rip out the old board and put in a new one?

Well, the motherboard is pretty much fixed whenever you install a CPU, so having it fall over and the like just doesn't happen. I've lost count of how many CPUs have been ripped from their ZIF socket because the thermal compound hardened, and this almost always leads to lots of bent pins, as does dropping the CPU. People handle CPUs rather roughly and having 1207 pins to bend would be pretty bad. With an LGA setup the socket itself protects the pins to a major extent.

How does hardened termal compound rip a cpu from its zif socket?! I guess I should check to see if my compound is hardened, I wouldnt want the CPU to get riped out!!

The hardened thermal compount rips the CPU out of the socket when you try to remove the heatsink, that's why people recommend "warming up" the CPU and giving the heatsink a little twist when removing it. Do you understand or do I need to draw it for you?

ive pulled my 754 newcastle out of its place several times, still works like a pretty penny.

Where are you buying a $600 quad-core opteron CPU from?

I don't see any reason why these Socket-F boards should be significantly more expensive than existing Socket-940 boards with the same amount of sockets. Fast Socket-F CPUs will still be several times more expensive than Socket-F boards.

You guys are missing the actual reason Intel switched to the LGA socket. They wanted to decrease the thermals, although I have no idea how the difference in socket could possibly keep the temperature lower, not to lessen the hazard of bending a pin. Think about it in a capitalistic way. It makes no sense for a company to decrease the risk of a costumer having to buy another of its products. Intel and AMD would love for you to accidentally break a pin on your Extreme Edition or FX that you just blew a grand on.

No, I think the article has it dead on. read what this guy wrote from the other article thread
