Sometimes it is, sometimes it isn't..... Also, all of the boards I have had this problem with were using only one CM9 at a time. I have also run dual SR5s in RB5xx turned all the way up, with no problems.... I have one board now that started behaving exactly as this topic's title states, but has gotten worse to the extent that the top slot no longer works at all.... I now use the board on my test bench, and have the CM9 in the bottom slot. I noticed that the newer RB511s used a black Mini-PCI socket instead of the white one I was used to, so maybe there was a problem with a batch of Mini-PCI sockets???if you plug off the power and plug it back - is everything fine then?
John:You should set the CPU to 266MHz (the RB532 model). This works for us with two SR5 cards.
I would think that at 333mhz, supplied 24v 1.25A that it would be able to run one card fine. Im not totally convinced this is an overclocking issue....Is this whole problem a 333MHz "overclocking" issue ?
Does sound a bit like could be PCI bus timing stability at that speed.
Am about to order some of these cards for testing, would like to know also ...
Test what exactly?!? My process of elimination, we have all eliminated a lot of things. We confirmed this issue isn't specific to the SR2/5 cards as some expierenced this with CM-9 cards. We also confirmed this issue took place on both 513 boards and 532's. We also confirmed that overclocking is not an issue, and I have confirmed it has nothing to do with running two cards at the same time. Some one else also mentioned this happened on an intel board. The only thing left is the OS, and MT support pretty much just tells me the mini PCI card is broken and thats it...piss poor help in my regard.You should first test and then we can try to check something else.
So the 513's don't support the SR2/5 cards? No I did not confirm that I set the speed to 266, but others had mentioned they had this problem using the boards at 266mhz. It is something I will certainly try, but I am not positive it will help as it has not helped others. Not to mention others had problems with CM-9 cards in these boards as well!?!?The first 500 boards shipped do not support more than 9W of power. You can tell this by looking at the board. It does not have a connector on the pads that are marked 'Daughterboard.' They may have problems with the non-standard mpci SR cards.
Also, you have not confirmed that you have set the CPU speed to 266MHz. You should be clear in your response. I asked you to try that, and you said you didn't think it was needed. Then I said you must try this. Now you say 'piss poor,' but don't confirm whether you have tried 266MHz or not. If you do not write clear responses, then I can't help you.
