Re: Does anyone have experience with a SuperMicro X9SBAA-F y

the biggest argument against this particular MB is the memory: ECC SO-DIMM. Approximately, the unbuffered DDR3 ECC SO-DIMM cost double compared to the standard UB DDR3 DIMM. Support for ECC memory is one of the biggest advantages of the Centerton Atom, cost is not the issue, for a server data integ...

Re: Does anyone have experience with a SuperMicro X9SBAA-F y

Thanks for your reply. Yes, it's for a home file server and will be running Linux. I'm not fixated on any specific mobo brand, I'm just looking for any mobo with the Intel Atom Centerton cpu, the brand of the mobo is secondary, what I care more about is the features (as I said I would prefer 6 SATA ...

Does anyone have experience with a SuperMicro X9SBAA-F yet?

I'm quite interested in a mobo with the new Intel Centerton Server Atoms (they support up to 8GB ECC RAM and virtualisation in addition to EIST), so far the only board I could find is the SuperMicro X9SBAA-F which seems interesting but I would have liked 6 SATA ports rather than just four, or at lea...

I received the following email from a reader of my DN2800MT review , I thought since it contains useful info I might post it here. Please be aware I have not tried what suggested in the email since my DN2800MT is currently in use as a headless server, so I don't know if it works as described! Great ...

Re: Intel DN2800MT hands on...Single digit world?

P.S. Linuxman - in my first post, you are correct, I meant that the display has a native 1920x1080 resolution, but when attached to the dn2800mt with lubuntu (and others except MeeGo) mostly only gives me 1280x1024 (except for the one time I got 1600x1200, which still isn't native resolution).

Hi! I would really appreciate any help on getting the dn2800mt to work under Linux (preferably ubuntu, not MeeGo). My email is phil@philtroy.com. I have a 1920x1080 driver and it only displays 1280x1024 (which is the only fix I need right now). What do you mean by "I have a 1920x1080 driver", did y...

I noticed s2ram -f disabled my video output. Do you get the same thing and does that lower the power consumption (I don't have any decent power meter)? In that case, I guess one should suspend and resume after rebooting. There was a BIOS update in the meantime by the way. The documentation mention ...

Re: Intel DN2800MT hands on...Single digit world?

You know, I always wondered about that. And what you say confirms my suspicions and makes sense: in the case of an IC, "real work" and "making heat" are effectively synonymous, right?

Re: Intel DN2800MT hands on...Single digit world?

Not all power draw is wasted as heat; depending on the efficiency of the device, some or most of the power will be doing "real work" (as opposed to just making heat). Actually that's a common misunderstanding. Electrical energy can only be transformed into heat (to be more precise radiation of some...

Re: Intel DN2800MT hands on...Single digit world?

I have a DN2800MT being tested in the lab right now, but my power measurements differ from yours. The main difference in the gear is 4GB RAM instead of 1GB in yours, and the use of a "level V" efficiency 12VDC power brick. The latter, at full load (60W), is supposed to reach 87%, compared to 85% fo...

I have now repeated all tests I did with Win7 using exactly the same setup with Centos 6.2.

The difference varies between 1.5 and 2.4 Watts depending on the specific test, which I...

Yeah, your measurements are the best we got. But if you compare them to other people's readings, you take their errors on board.
