Title: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: CrazyGuy on September 06, 2011, 03:47:33 AM Looking to buy AMD motherboards with 5 to 7 PCIe slots. Any combo of 1x to 16x slots, just as long as there are 5 to 7 total.

Only thing I've been able to find that's close that you can use all at x16 or x8, is this http://www.fullcompass.com/product/393427.html expensive I know, but it's all I've been able to find. I know MSI released a board last month that has 8 slots on it, only 4 can be used a x16 and 4 at x8.
Hope this helps. -Matt Title: Re: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: CrazyGuy on September 06, 2011, 04:30:32 AM heh.. you and I are looking for the same thing.

I know MSI released a board last month that has 8 slots on it, only 4 can be used a x16 and 4 at x8. Woah! I like how they throw "cost effective" in there. Seriously though, there's no reason to run your cards at 8x or 16x, unless you're gaming. I've got a cheap ud3 with 2 16x, 2 4x and 2 1x slots. I'm currently using 5 out of 6 slots with all hashing at full speed (Waiting on a 6th extender.) UD5 has 7 total slots and it's $179 brand new. I was hoping someone may be selling their used MBs with at least 5 slots, 1x to 16x, doesn't matter. 8 would be great but I don't think there are many out there.Hope this helps. -Matt Title: Re: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: logansryche on September 06, 2011, 04:37:42 AM Not that i'm aware of.
Title: Re: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: mb300sd on September 06, 2011, 04:45:01 AM Theres always the PCI to PCIe converters, I'm considering getting 3 to fully utilize my motherboard... Their a bit expensive, but its a lot cheaper than a new board, new ram, and a new CPU. Not sure about power draw, but I solder SMT chips every day, so cutting some power traces and adding a molex to a board isn't a big deal.

Great board Not bad, UD3s going for $149 with free ship on new egg at the moment. Anyone want to get rid of some used Motherboards? I've got some BTC burning a hole in my digital pocket.https://bitporium.com/components/mother-boards/msi-890fxa-gd65-890-am3 ~$159 Title: Re: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: CrazyGuy on September 06, 2011, 05:03:10 AM Theres always the PCI to PCIe converters, I'm considering getting 3 to fully utilize my motherboard...

Not sure about power draw, but I solder SMT chips every day, so cutting some power traces and adding a molex to a board isn't a big deal. Do those work pretty well? Require any special drivers? How much do the converters usually go for? These will be for brand new mining rigs but if I can get a motherboard with 2 PCIe and 3 pci for 50 bucks, and converters aren't that expensive, might not be a bad idea.Title: Re: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: logansryche on September 06, 2011, 05:05:23 AM I'd be interested in those as well.. beats the alternative I laid out lol.

That's 90 dollars (last ones I saw where 30 each) just in extenders. You can get a complete second board, cpu and ram for 90 dollars.(albeit not new). Or just sell your main and get a better with more slots.

These will be for brand new mining rigs but if I can get a motherboard with 2 PCIe and 3 pci for 50 bucks, and converters aren't that expensive, might not be a bad idea.I haven't tried it yet, haven't used up my PCIe slots and with the current BTC price drops, I don't think I ever will. I'm using a board I had sitting around, with 4x PCIe and 3x PCI. I think their completely worth it when you can get really cheap or free board to support 7 cards. I'm not sure if they'll work with a no-PCIe motherboard, but I'll test it on my old Pentium 3 when it shows up. I'll make it my primary mining rig just for laughs if it works :D http://www.ebay.com/itm/PCI-E-Expresscard-X1-X4-X8-X16-PCI-Card-Adapter-New-/180645720134?pt=LH_DefaultDomain_2&hash=item2a0f52f046#ht_2781wt_952 Title: Re: [WTB] - AMD Motherboards - 5 to 7 PCIe slots Post by: xurious on September 06, 2011, 05:27:03 AM Theres always the PCI to PCIe converters, I'm considering getting 3 to fully utilize my motherboard...

Isn't the reason because the PCI slot cannot supply enough power? I have no problems modifying the converter to supply the GPU power from a molex, and/or using an extender with a molex.

For some reason when running two of these card adapters while mining, it will just fry out the whole slot. I have this confirmed from 2 others as well. One was trying to run 4 at once, the other was running 2 like my self.
