EPP Question

[Krebs]

Im looking to build a new computer in the upcoming weeks, and ive run into a problem with mobo and memory compatibility.

Im looking to use Corsair TWIN2X2048-6400 4-4-4-12 on a ECS KA3 MVP board.

i've found out that the two are compatible however Corsair says that the memory can only run at those settings on a EPP enabled board.

So, can anyone explain to me what EPP is, how it is different than JEDEC, and is it only compatible with some chipsets, or are most mobos EPP enabled

Don't worry about it, either Corsair was wrong or you misunderstood them. EPP is just an improved version of SPD. In order to use it, both the memory modules and the MB need to support it. Currently only certain Nvidia chipset MBs support EPP. However, you can manually adjust the memory speed, timings, and voltage to the proper values. This post should help explain things:
