I have the MSI 890FXA-GD70 on it's way since I got it for $59.90 after rebate. It has 6 PCIe slots. This MB has been discontinued so you will have a hard time finding it. I was lucky to find one.

If I had to choose something else I would look at:

MSI Z77A-G45   LGA 1155    7 PCIe***   $114.99  after  $10.00  rebate card at newegg

Searching the forum didn't find much on the Z77A-G45 though so I don't know how well it works for mining.

Don't know of any MBs at a reasonable price with 8 PCIe slots

I looked at using the Gigabyte GA-990FXA-UD7 myself but I believe it has a supplementary SATA power connector on the motherboard to adequately power 4 way SLI.

Cablesaurus states on their powered extenders:

"For use only with traditional motherboards using only a CPU/ATX motherboard power connector, and no supplementary SATA power connector on the motherboard"

Ouch! Hadn't factored in the cost of the CPU 

Argh!

Guess I'm back to the Gigabyte GA-990FXA-UD7.

After spending the last two days trying to select a motherboard I have finally decided on the Gigabyte GA-X79-UP4.

Was initially going to use the Gigabyte GA-990FXA-UD7 but read that Intel CPUs use less power when idle. I also have a personal preference to Intel.

Here are my reasons for selecting the Gigabyte GA-X79-UP4

• The Gigabyte GA-X79-UP4 allows me to use up to 4 GPUs without risers in a HAF XM.
• If I decide to later use a custom cage it will let me go up to 6 GPUs with risers.
• I bought into Gigabytes "Ultra Durable 5" marketing.
• Only a little more than the GA-X79-UD3 with "Ultra Durable 3".
• 5 year warrantee.
• Availability

I think I'll be ok in regard to cooling as this will be placed in a data center with an ambient temperature of 61 degrees.

Having searched the forum it doesn't appear that this motherboard has been used much. I read that the MSI 890FXA-GD70 is the one to get but it is hard to come by. The MSI Big Bang-Marshal would be nice but twice the price for two more slots.

Any feedback would be appreciated!

Was online for about 2 hours yesterday and about 6 hours today but the board says I'm still under 4 hours....Hmmm

Have spent the last two days lurking and even purchase the following equipment:

Corsair AX1200i
Cooler Master HAF XM
MSI R7950 Twin Frozr 3GD5/OC       (delivery next week)

Now I just need opinions on the motherboard. Thinking of using a Gigabyte GA-990FXA-UD7 since it supports 4 GPUs but am not sure...

Thanks for the whitelist!

I can attest to that. Only thing is I didn't know about the 4 hour rule so I hadn't bothered to register for an account until I was ready to post :/

I just got my first payout on give-me-ltc.com. Is it common to not get the full 1 LTC? I only got 0.99246693 LTC.

Started mining a few days ago. Glad to find this forum as a resource!
