Title: 4 x Radeon 7950 Spec - Advice Needed Post by: elliotp on April 22, 2013, 03:00:44 PM Hi,
I need some solid advice on a few items in my spec, as i'm getting mixed opinions on several factors, so i need someone with a similar setup to comment if possible. **** This is for LTC mining. Motherboard: Gigabyte 990FXA-UD3 CPU: AMD Bulldozer FX-4 Quad Core 4100 Black Edition 3.60Ghz Memory: 8GB DDR3 GPU: 4 x Gigabyte ATi Radeon HD 7950 PSU: OCZ ZX Series 1250W '80 Plus Gold' Modular Power Supply Case: DIY Open frame design with some extra fans. 1) I've been told the cpu is too much, and i can get away with a Sempron - the last thing i want to do is limit the system due to lack of cpu power. 2) Do i need active PCIe risers? The board is a 5 slot pcie 16x, i'm only going to be using 4. Can i get away with just cheap standard riser cables? Thanks, Title: Re: 4 x Radeon 7950 Spec - Advice Needed Post by: middlemarkal on April 22, 2013, 04:01:39 PM the rule is more then 3 you need power riser ;D

Is the powered riser help in case I wish to overclock ? |
