Regarding the MSI BigBang Marshal B3

[likuidxd]

I have seen a bunch of post in hardware asking if this board works with no replies to them, that I have seen. I am new, 1st post, so I can not answer these guys.

Yes 8 PCIe ports populated and mining with HD 5870's.

I know it doesn't matter much for mining purposes but if you'll use the board later on for gaming or something else,
4 slots - 8x
2 slots - 4x
2 slots - 1x

No hiccups running LinuxCoin, will be trying BAMT later today. Had to install and use ATITweak instead of ATIconfig and AMDOverdriveCtrl. I don't consider this an issue though as ATITweak if far better IMO.

Only issue with having 8 PCIe ports populated with GPUs is power. I am running off a 120v outlet and the wire gets hot! If this is a rig you're going to look into, use 5830's or use a 240v outlet to power it.

~3.2GHs @ 1550W

What works

Motherboard:
MSI Big Bang Marshal B3

CPU:
Intel i7 2600K

Memory:

PSU:
Antec High Current Pro 1200
Antec TruePower 750

I will post a screenshot up later when I get a chance for proof of operation and stability

Don't waste money on new with this board either. I purchased an open box from newegg for $279, saved a hundred bucks and it came perfect.

Happy Mining!

Nice build! What settings do you have changed with atitweak?

atitweak -e 900 -P 2 -A all
atitweak -m 600 -P 2 -A all
atitweak -f 65 -A all

OC'ed the core a bit and took down the memory otherwise I'd blow the circuit at well over 15 Amps and more than 125 Volts

I can't seem to stabilize under 600MHz on the memory though

That board is bamf... Putting it on my want list!  ^_^

Can't fit into a full tower, it requires E-ATX casing or you may want to run it as open rig.

There are a few cases that support XL-ATX, but you'll only be able to run 4 cards sandwiched together. The board does support 7 case fans though. Open air is the only way to go for dedicated mining rigs.

Open rigs are the best no doubt, but a lot of datacenters refused that.   We have to pay extra for the electricity and also ensure "closed" rigs.

Hi mate, how could you run 8 vga's in the marshal? i was running 8 vga too (2xHD7970 / 3xHD7850 / 3xHD6670) and in the device administrator just 4 are visible and 4 got the yellow question icon and the cgminer don't see those 4 vgas.... why? can you help me on this? Sorry about my English but im from Argentina.

I really need you help likuidxd, i got two Marshal's already and only work whit 4 each one...
