new system - recommend chip sets / motherboards
I would like to put a new AMD64 4.9 system together. My current computer is 4-5 years old. I figure should replace it before it dies. Normally, I just buy a motherboard and assemble the system myself.
I am wondering what the best approach is to getting hardware that is compatible. I saw the ' hardware support' thread by rgb_cn. It said to avoid newer chip sets, on board graphics and nvidia vieo. My guess is that a lot of the motherboards that are in the stores are probably not supported because the chip sets are within the last 6 months. Does one need to buy motherboard now and tuck away for a year or so? I am looking at AMD motherboards because I remember seeing various threads about how intel did not implement W^X correctly. I also have the impression that AMD is open source friendly as they donated hardware a ways back. Several of the motherboards that I looked at have AMD 850 or 880 chipsets. I see the following mentioned in the change log for 4.9: ChangeLog.34:PCI id is shared between the SB600, SB700 and SB800 chipsets. ChangeLog.34:mention the AMD SB700 and SB800 chipsets. ChangeLog.34:- rename some SATA entries which are shared between the ATI SB700 and SB800 chipsets ChangeLog.34:- add some new SATA entries for the ATI SB700 and SB800 chipsets I tried: 1. man -k on several terms, it did not find anything usefull for various terms that I put in for chip sets. (On 4.9) 2. I also looked at the 'Your OpenBSD Hardware', but there is not a lot there that is recent. 3. Various searches on the web. I am not looking for super fast video or latest hardware. My current system dual core AMD 64 3800. I certain do not need a video card with fan because that is just a waste for me as my current embedded (hate to say it) nvidia had enough performance for me. I am looking for a system that works reliably and does not have issues. For example, I saw a thread about some hardware that had a very high interrupt rate that causes a bit of a performance issue because it was a bit too new. Would intel motherboard be better than AMD? Anyway, just looking for some guidance to get to some specific. If I am not reading something that I should have read, feel free to flame me. |

If you're in the states NewEgg has a nice feature allowing you to "drill down" by chipsets.
The amd motherboards in this link with 740G and 760G northbridges should work (ATI Radeon 2100 and 3000). Newegg AMD motherboards as of 1Aug2011 I also asked and got a reply in this forum that Intel NM10 chipset has OpenBSD intel video support (but not FreeBSD). I have not tried an NM10 to verify but I have an older Atom 330 board that runs well. If you want a fan less low power solution this page has some options - The Atom 525 is dual core and 64bit.

Thanks for pointer and the suggestion of the 7xx chip sets.
I found a local store that that had one last gigabyte GA-MA78LMT-S2. I just installed 4.9 amd64. Seem to be working well; this includes the onboard video at 1920x1080. The only issue that I have noticed so far is that it only sees about 3/8GB of memory as displayed in top and vmstat. I thought that large memory was solved/fixed. I will do some searching around to see whether I can get it to be able to access the rest of the memory. Anyway, thanks for the help. Last edited by jsmith6134; 8th August 2011 at 05:42 AM. |

http://undeadly.org/cgi?action=artic...20110413140750 OpenBSD 4.9-release was tagged in CVS mid-February, so the results you are seeing with 4.9-release are correct. If you need to access all available memory, you can do so by installing -current (only for amd64). |

That is the message I remember seeing. I don't need it now, just wanted to make sure that nothing was wrong. I can wait for 5.0 to be released. I will run memory testing for a day or two to ensure all 8GB is OK.

While waiting is your prerogative, installing a snapshot now has one potential benefit: if issues need to be addressed, there is a possibility that the underlying problem can be resolved before the 5.0 code base is frozen in a few weeks. If you wait until the release of 5.0 in November, any unforeseen problem may not be corrected before 5.1 -- which would be formally released in May 2012.
