Thuban compatibility with AM2+ Motherboards
I would like to ask subscribers to report in this thread links to
attempts to use AMD Phenom X6 (Thuban Core) in AM2+ motherboards with the following chipsets: 790FX + SB600, 790FX + SB750 and 790GX + SB750. Are there any AMD people here who can provide insight into real backwards compatibility to AM2+. I need to know if I can upgrade 20+ AM2+ motherboards from various Athlon II / Phenom II to Thubans. So far, the motherboard makers have been silent. I am kinda stuck with high-end AM2+ motherboards with loads of ECC DDR2 and it would be golden if I could upgrade all these to six cores. I am not interested in TurboCore feature so if that only works with newer 890* chipsets it is not a loss at all. |

Thuban compatibility with AM2+ Motherboards
I just looked he
http://www.cpu-world.com/CPUs/K10/AM...BGRBOX%29.html and I don't know if they got it wrong or these new chipsets lack the DDR2 controller. On the other hand, AMD's own Key Arch Features for the Phenom II line lists support for both DDR2 and DDR3: http://www.amd.com/us/products/deskt...-features.aspx Is it true that they only work with DDR3? :/ |

The X6 is 125W, while many MB's only officially support 95W or less. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

The X6 is 125W, while many MB's only officially support 95W or less. Oh, no worries there. It ran 125W X2 6000+ then a 125W Phenom X4. Well, I sent an email to Gigabyte and maybe they'll sort this out. |

Thuban compatibility with AM2+ Motherboards
Sadly, the flagship AM2+ motherboard from Gigabyte ( the DQ6 with 790FX
+SB600) is listed as NOT SUPPORTED. It seems all motherboards with SB600 are plagued by this... I guess upgrades will have to be limited to quad core Phenom variants : ( So much for backwards compatibility... |

I guess upgrades will have to be limited to quad core Phenom variants : It may still work, but just be limited in some way. Same as with early versions of the K7 Athlon socket A (462). All newer K7 CPU's would work in them even though they weren't officially supported. Here's what I got with an Athlon XP 2100+ (rated at 1733MHz) in my old KT133 MB not rated for XP's using a 24x multiplier. processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 8 model name : Unknown CPU Type stepping : 1 cpu MHz : 2400.188 cache size : 256 KB -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

Thuban compatibility with AM2+ Motherboards
Well, I'll give it a try anyway.
The thing is I need to put it into multiple systems that are acting as a ' poor man's cluster ' and I value stability. As soon as I get my hands on an X6 I'll test it in the AM2+ motherboards I have and post results. Still, this is a disappointment. I was expecting more from a 220E motherboard. |

Thuban compatibility with AM2+ Motherboards
Well, I got one and tested it and it doesn't work with SB600-based
AM2+ motherboards. I tried 3 mobos ( 2 Gigabyte + 1 ASUS) and it won't POST with a X6... As a rule of thumb, users with AM2+/SB600 should limit themselves to X4 Phenom II CPUs or switch to a AM3 motherboard or AM2+ with SB700 or better. |
