X58A-UD3R vs X58A-UD5

Last response: in Motherboards
Share

What's the difference? On the gigabyte website looks like the X58A-UD3R has 6 Ram slots unlike the non 'A' version and on spec sheet looks identical to the UD5?

Since they cost difference what's the difference? Heck, what's the difference between these two and the UD7?


Since there already has been some confusion, I am referring to the new X58A boards that have USB3 and SATA 6gb, NOT the EX58 boards that don't.

The same?
The HUGE difference is the 3R has only 4 memory slots while the UD5 has 6. With triple channel memory this difference is a major one.

The UD5 has 3 x16 PCIe slots compared to only 2 for the 3R - although the of the 3 on the UD5 2 are at x8 speed. The 3R does have one more x1 slot though,

The UD5 has 10 SATA connectors compared to only 8 for the 3R.

The UD5 has eSATA connectors (by cable) while the 3R has none.

The UD has copper heat pipes compared to aluminum ones on the 3R.

This information is all reported on the comparative analysis - and I beleive on the individual spec sheets.

How can you say they show no difference?

I am talking about the X58A boards! The ones with USB3 and SATA 6gb. jfreggie links the comparison of the old boards. While the EX58-UD3R only had 4 memory slots, the X58A-UD3R has 6 memory slots!

What difference? I see none except they say the X58A-UD5 has "Dual" GbE LAN and the X58A-UD3R has "2" GbE LAN. So if they are identical except for that I'd rather save the 60 bucks and get 2 LAN instead of dual LAN.

X58A-UD5 also has compared to the UD3R:
Advanced 12+2+2 power phase design with VRD 11.1 support
Onboard Debug LED display simplifies motherboard troubleshooting
2 Gigabit Ethernet LAN with Teaming functionality
Power/reset/Clr CMOS onboard button for easily operation on the workbench

I was wondering the same exact thing. I couldn't really find a difference. The comparison sheet on Gigabyte's website showed all the same specs for both. I ended up going with the UD3R since it was quite a bit cheaper.

I'm stuck between the UD3R and UD5 now as well.

From what I can see..

The UD5 has (much) better northbridge cooling, for better overclocking.
The UD5 has another GbE port.
The UD5 has better power power management (8 phase for UD3R, 12+2+2 for UD5).
The UD5 has a POST Debug LED light.

The UD5 and UD3R both have power/reset/clear cmos buttons (I believe).

But is the UD5 worth $50-60 extra? I don't know...

Any one know how well the dual lan ports performs on the UD5. Are they good quality? I plan on purchasing it and was wondering if it is worth getting the UD3R instead and buying a separate lan controler.
Motherboard Authority

A cursory google will show that pretty much all the RealTek LAN stuff has significant problems when 'teamed' on a wide variety of switches that support it...

the UD3R boards have the LED debug lights as well for the different areas of the board - so that would be the same as the UD5

perhaps the only differences are the power management and extra GbE port (with a side of extra cooling capability)

I just called Gigabyte today and asked them if there is any other difference.

They said (additionally to what we discussed)

The UD5 has another layer in the PCB (is this good or bad?)

and The UD5 has hardware-based 3-way Xfire/SLI and the UD3R has software-based 3-way Xfire/SLI.

2-way SLI/Xfire is the same on both boards.

The question is really:

Is the UD5 really worth $55 more than the UD3R? :\
