Does anyone know what "CPU0 to GOLEM0 Tx Speed select" means on a dual opteron motherboard? It's a BIOS setting. -- Anders Norrbring Norrbring Consulting

I have no idea what GOLEM0 means (neither does google), but considering that there's a CPU0 to CPU1 thingy too (have a look at this: http://www.rioworks.com/Download/hdama%20rev.e/manual/HDAMA%20Rev.E.pdf), I would guess it's the hypertransport bridge speed between the CPU and the rest of the machine, as opposed to the HT-bus speed between the two CPUs. Just a guess... Hans

Your guess is as good as my guess, Hans.. It is a HDAMA board I have (plenty, in fact), but I have never dared to touch that setting. I can choose between 600 and 800MHz, but that's hardly a good lead. Oh well, I guess I have to ask Arima support about it. Thanks anyway! -- Anders Norrbring Norrbring Consulting

Got a reply from Arima.. Our guesses was kinda good.. :) "CPU0 to GOLEMO Tx speed is an option to select speed link between CPU0 and Chipset8131." Now I just have to find out if I should set it to 600 or 800MHz.. :) -- Anders Norrbring Norrbring Consulting

I'm suprised you *can* choose 600mhz! As far as I remember the Hyper Transport bus was introduced at 800mhz, and has been bumped to 1ghz since. Hans

Yep, I don't understand that either. But since I didn't know before what that setting was, I left it at default (600). Now I've changed to 800 on all my servers, and everything looks just fine. -- Anders Norrbring Norrbring Consulting

All things considered, I'm not sure how much of a difference that would make, if it is what I understand it to be - link between the CPU and whatever is considered as the "north bridge," because any components haning off it communicate at much less than 600mhz anyway. Except maybe for AGP or 16x PCI-e but you're not likely to find/use those on a server board. Maybe I just don't know enough about the opteron setup - I've never actually had my hands on one.... Hans

I doubt it'll make any difference even if the board was to have PCI-Express or AGP.. The AMD 8131 (GOLEM0) chipset is the AMD-8131 HyperTransport PCI-X Tunnel, as can be seen on http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_4699_7980%5... --- Anders Norrbring Norrbring Consulting
