At the moment, there are no advisories listed at https://security-center.intel.com/advisories.aspx newer than April 3, so presumably either the piece is false, or else the firmware fix was released to OEMs but not publicly.

how can this be? Intel has promised me for 15 years now that this would never be an issue! There just has to be some mistake. Oh, right, now I remember. The ME is the mistake. ron On Mon, May 1, 2017 at 8:39 AM Shawn <citypw(a)gmail.com> wrote: > > https://semiaccurate.com/2017/05/01/remote-security-exploit-2008-intel-plat… > > -- > coreboot mailing list: coreboot(a)coreboot.org > https://mail.coreboot.org/mailman/listinfo/coreboot >

Hi Bogdan, I am running my KGPE-D16 with 2x6276 and 16 of these 8GB Samsung RDIMMs: M393B1K70DH0-YK0 They work fine in coreboot. If you want to run them at 1600MHz, you need to raise the voltage to 1.5V even if the vendor bios clocks them at 1600MHz with 1.35V. They work fine in this setting as well, although this is out-of-spec according to Timothy Pearson. I have no idea how to check if they run in quadchannel but appreciate any hints. You can find more info on this thread: https://mail.coreboot.org/pipermail/coreboot/2017-February/083151.html Please be aware that power consumption in idle on the KGPE-D16 is still a major issue with coreboot (~150W with coreboot while ~80W with vendor bios in dual-cpu config): https://mail.coreboot.org/pipermail/coreboot/2017-February/083195.html Also, if running the board populated with DIMMs in all slots the best bootup time for coreboot I could get was around 30s: https://mail.coreboot.org/pipermail/coreboot/2017-March/083595.html On the contrary, with just 2 UDIMMs, it booted up almost instantly. Please consider this as well when making the decision. Yet, I am happy to welcome more KGPE-D16 users and share experience. Cheers, Daniel

Hi BogDan, Your build is going to be really nice :). My comment was simply a generalized curiosity about how the Opterons stacked up against each other. Also as far as I can tell, the G34 motherboards seem to be somewhat easier to source.

Hi, Apart from features such as greater memory bandwidth, more cores, and more CPUS in an MP configuration (2/4), what are the advantages of the G34 vs C32 sockets? The C32s have CPUs with TDPs as low as 35w and more cores with higher clocks in a dual CPU configuration, i.e. the 4340 has 6 cores with a base clock of 3.5GHz. Two of these in configuration and you have 12 cores at 3.5 GHz. By comparison the highest clocked G34 is the 6308 at 3.5 GHz but with four cores, this in a two CPU configuration you get 8 instead of 12 cores at 3.5GHz. Is there a substantial difference in performance between these CPUs in practice (core and clocks being equal)?

Hi Zoran, Is not for gaming only :), it's *also* for gaming. I play games once per week and then I want my games to run ok. I'll usually using it for programming. Regarding why use coreboot instead of (AMI) BIOS, well, I think the question is why to use (AMI) BIOS when I can use coreboot ;-). I also want to *try* to help coreboot folks by testing coreboot and who knows maybe with patches.
