Does Asus A8N-E support dual channel memory? That`s all.

Supports AMD Socket 939 Athlon 64FX/Athlon 64 X2/Athlon 64

A8N-E supports AMD 939-pin Athlon 64 FX/ Athlon 64 processors with 1MB/512KB L2 cache which is based on 64-bit architecture. It features 2000/1600 MT/s HyperTransport Bus and dual-channel un-buffered DDR400 memory support.

P.S. sometimes Google is the best friend ...

Thank you

hmm can you tell me what that unbuffered means ?

Its not using registered RAM which is basically for servers. The idea behind it is that it takes an extra clock cycle and theres an additional chip on the RAM stick that repeats the signal it gets from the PCB side of the RAM and makes sure that the signals are all correct, and if there is any erroneous transmissions it corrects them.

No need to worry about it in other words

oki doki

Supports unbuffered... but would i be right in saying that you CAN use buffered? (although why anyone would want to..... is beyond me for the price of buffered)

It does support buffered but I think in most cases, for example if you buy an AGP8x card and stick it in a 4x slot, the 4x slot still says "Hey this looks good enough to me" and just runs it at 4x, and ignores the fact that its an 8x card because it doesn't know any better....crappy little analogy but it follows that same sort of process. It will support buffered or registered RAM I believe, but you won't receive any of the benefits. Don't quote me on that though, I'm guessing on this a little bit

well i'm pretty sure the althlon memory controllers support the ECC checks.... but i haven't really looked into it at all or it really doesn't matter to me....

H3X4D3C1M4L · Dec 17, 2005, 12:49 PM

Yeah but the ECC for the system RAMH as to be supported on the motherbridge, the Athlon XP's only support ECC for their L1 and L2 cache, the ECC for RAM has to be in northbridge

Judas · Dec 17, 2005, 09:35 PM

939..... or 754 for that matter or 940s don't have north bridges... the memory controllers are all built in..

939/940s are pretty much identical.. making opterons even for 939's which i'm sure have ECC support....

H3X4D3C1M4L · Dec 18, 2005, 11:02 AM

I know that :P but the memory controllers for A64 CPU's won't support ECC. Socket 940 does, thats what the extra pin is for on that memory controller, but 939 has no ECC. The FX51 was basically a rebadged Opteron and ran on Socket 940 with slower ECC memory.

Judas · Dec 18, 2005, 11:32 PM

....i thought the extra pin was related to something completely different.... and that all x64 cpus are made with the same memory controllers. IMO, i doesn't make any sence not to support ECC at all.. considering that even older boards supported ECC on nearly every chipsets...

I just put the A8N-E in my main computer two days ago. Replacing my love Hate relationship with My ABIT AV8 to one of Pure Love with Asus...

Well that might be laying it on a bit thick. The ASUS is excellent and i built a ASUS A8N-VM CSM two days prior to that. No hitch in either build.

I broke my AV8 down and used some of its components for the little integrated board, (Winchester 3500 and 160Gig Seagate Sata HDD) adding some new 2 x 512 Super Talent PC3200 Cas 2.0, and a new In-Win case

My A8N-E kept the old case and PSU and Ram. (Antec P-160, Seasonic 460W, Corsair 2 x 512 PC3200XL) and I added a Opteron 148, AC Freezer 64 Pro, A WD 250 Sata II HDD.

This really is a improvement over my old Via based board.

I like ABIT's BIOS layout much better, but I don't go there much if all is working well.

ECC requires extra clock cycles and more expensive hardware and to be honest it isn't really needed by the average desktop user... its only of any real use in a heavy duty cycle server where data reliability is prized over speed.

I built a system around an A8N-E not long ago, Ive had to replace the chipset fan already, It absolutely screamed and was visibly off centre. After googling this is apparently a common fault though apart from that it's been spot on.

H3X4D3C1M4L · Dec 23, 2005, 08:09 PM

That's most mobo's though, infact most of the time I just replace the NB cooler before I use it

[Aura]W32Led@mm · Jan 4, 2006, 04:37 AM

Btw what bios ver. is in A8N-E rev.2 ?

REV2.0 fixed this issue.

As for the ECC... i know the average or even above average desktop user isn't in any need of it. I just could have sworn AMD's intergrated memory controller support ECC

H3X4D3C1M4L · Jan 4, 2006, 01:14 PM

That's probably because the intial batch of FX procs were Opteron 940 based and supported ECC
