Will ECC work with FX4100?

[tangoseal]

I just need to build a low cost server for FTP/Web (low volume), and some other very minor services that will sit at a business I have permission to use bandwidth at for testing stuff out.

I was looking at the Atom D525, E-350, but then I came across the FX4100, low end AMD but does it support unbuffered ECC? I know some of the basic AMD mobo's will allow it but I think the CPU has to support it also.

Can anyone confirm this? And also what do you guys feel about it's performance/price ratio?

I do not necessarily care about power usage as it will NEVER hit 100% with the lights loads I will give it.

Thanks!

I was under the impression anything from AM2 onwards, with the right motherboard chipset/bios would support ECC, FX-4100 included.

saw an earlier post of yours on intel subforum discussing the advantages of AMD CPU over cheap intel chips b/c of ECC support. found it pretty funny you started a thread here to 'double-check'.

anyway, this is from anand's review of the Asus CHV
http://www.anandtech.com/show/4955/the-bulldozer-review-amd-fx8150-tested

AMD does offer six 6Gbps SATA ports on its 990FX chipset, a significant upgrade from the two 6Gbps ports on Intel's 6-series chipsets. Unbuffered ECC memory is also supported for those who desire the added security, once again a feature not supported on Intel's consumer grade 6-series chipsets.

tho i recon this PDF is of more value as it's from AMD...

• Integrated Memory Controller
• AMD Memory Controller PowerCap
• Low-latency, high-bandwidth
• DRAM Prefetcher:
• Adaptive prefetching support
• 32-entry DRAM prefetch table
• Differentiate between core prefetch requests and core demand requests
• ECC checking with double-bit detect and single-bit correct
• 144-bit DDR3 SDRAM controller operating at frequencies up to 1866 MT/s (933 MHz)
• Package AM3r2
• Supports up to four (4) unbuffered DIMMs

i guess the only limitation is whether or not the MB supports it. i'm guessing most do?

regarding whether or not it's worth it (to sacrifice performance -per clock/per watt), is kinda irrelevant considering intel doesn't even offer ECC support outside xeon/enterprise stuff.

Actually I don't think most amd boards support it, although many asus boards do...

Thanks! I was not sure. I am NOT up to speed on AMD for the last 2 years (Other than server - which I am very up to speed on). And actually my other thread was discussing ATOM not AMD.Read the thread more before you assume something. I have learned since starting that thread that AMD mostly offers ECC on all their desktop products. I wasnt sure about the 4100 though.

In that other thread why would I end up getting a celeron with no ECC only one or two cores for more money over all than a Microcenter special priced $109 for motherboard and FX4100 quad core. It would make no sense. Especially after I learned this stuff after making that thread.

So what is funny?

I do appreciate the links and information you provided as it was very helpful.

I run ECC RAM on a Crosshair V with FX-8150. Kingston low voltage 1333 overclocked to 1866 at 1.45V.
All Bulldozer CPUs support ECC but the BIOS has to turn it on.

depends on how cheap the board is.. heck even my pos biostar board that i have supports ECC and that was a 60 dollar motherboard brand new.

true you were discussing atom tho you did mention AMD bobcat cpu/system in the next sentence as an alternative for your requirements.

what's was so funny, nothing really. i usually see a few of your posts every time i check H forums. generally (from my subjective view of course) you seem to favour intel gear. with that in mind, found it amusing that you'd be looking at AMD gear for your little project. that and you have a fairly full-on intel system in your sig.

anyway it makes perfect sense to me why you'd want to pick up a 990FX/990X/970 chipset MB with a 4 core FX CPU. as you've stated, a low end intel system just fails to meet your needs (no ECC, more expensive, etc). you have no argument from me on this. besides, an argument conducted over a forum is a fairly fruitless excise.

happy to provide info you needed to make a decision.

not sure if this is the case with all Asus AMD chipset MB's but the CHV has the ECC option 'enabled' by default. kinda silly as most would be using non-ECC RAM on their CHV's, myself included.

depends on how cheap the board is.. heck even my pos biostar board that i have supports ECC and that was a 60 dollar motherboard brand new.

this i what i thought. believe AMD has supported ECC via CPU/chipset for quite awhile now, perhaps since they incorporated the memory controller on die?
