The brand new Intel Xeon W-3400 and W-2400 collection of workstation CPUs are each LGA4677 socketed CPUs, however they’re fairly totally different. Because of this, there are literally two totally different retention brackets with totally different keying between the 2 processors. What is probably extra intriguing, is that one can nonetheless use a Xeon W-2400 in a Xeon W-3400 collection motherboard. At this time, we’re going to present the 112L E1A and 64L E1B brackets and how you can inform which one to make use of.
Above is an image of the 2 highest-end CPUs from their respective product strains, the 56-core Intel Xeon w9-3495X and the 24-core Intel Xeon w7-2495X. Under are the 2 brackets for the CPUs.
To many, this will not be apparent to tie a chip to a bracket, so that’s what we wished to point out.
Intel LGA4677 112L E1A Bracket
The Intel Xeon w9-3495X makes use of the LGA4677 112L E1A bracket. 112L is the variety of PCIe Gen5 lanes (112 lanes.)
The E1A is printed on the CPU underneath the mannequin quantity. That ties to the 112L/ E1A bracket that comes with motherboards just like the ASUS Professional WS W790E SAGE SE.
Right here is the reverse facet. We will even see the TIM Breaker lever put in on the bracket.
For many platforms, there might be an E1A bracket for Xeon W-3400 collection CPUs.
Right here is the Intel Xeon w7-2495X. We will see the CPU’s warmth spreader seems fairly a bit totally different.
The CPU nonetheless has the E1B printed on it. That ties to the 64L/ E1B bracket that the motherboard comes with.
Right here is the reverse facet. The keying on the highest and backside of the bracket is totally different from the E1A model.
There are a number of different variations. Whereas they appear comparable, and each use the LGA4677 socket, we now have two totally different brackets.
Closing Phrases
Previous to getting each CPUs and the brackets in hand, we didn’t assume there can be a bracket distinction between the 2 CPUs, but right here we’re. It seems like there ought to solely be one bracket for a similar era of workstation processors. The excellent news is that after one sees the E1 on the LGA4677 socket after which sees the E1A or E1B on every CPU, it’s pretty simple to tie these collectively.
We hope our readers discovered this handy. It might be an article to maintain bookmarked for the long run. It’s a little bit of reference materials that we’ll come again to as we kick off our Xeon W-3400 and W-2400 protection with an enormous piece tomorrow.
