ASUS 990FX R3.0 AM3+ Sabertooth Preview

Introduction and Technical Specifications

ASUS 990FX R3.0 Sabertooth Preview


We have big love for AMD here at OC3D. For some of us the Thunderbird was our first CPU beyond 1GHz, and the Barton core range gets us moist with memories of blistering overclocks on DFI motherboards. So we're always a little disappointed in how long it is taking AMD to match up to the Intel range of CPUs.

However, we know that many of you are running an AMD CPU and it seems annoying that sticking with an affordable foundation for a gaming PC robs you of some of the very latest features and technologies that have been appearing on the Intel offerings. ASUS must have felt similarly upset as the have just released the third revision of their 990FX Sabertooth motherboard, now equipped with all the high bandwidth goodness that you would expect to find on a new motherboard.

Let's give you a quick overview of what you can expect to find.

Technical Specifications

Considering that the AM3 socket, and indeed the 990FX chipset, are long in the tooth now we'd resigned ourselves to the possibility that it would take a wholesale revision of the AMD range before many of the features that are included on the Sabertooth found their way to the AMD platform. Even a cursory glance through the specifications shows how hard ASUS have worked to bring it bang up to date though.

Okay so the Memory is still DDR3, and not exactly fast, but that's a limitation of the chipset. Equally we're only at PCI Express 2.0, again, 990FX limitations. Anywhere that ASUS could make a difference though, they have done.

So we have the AURA lighting. Not some cut-down version just good enough to make an appearance on the box without inciting lawsuits though. This is "ASUS Safeslot PCI slots with LED inserts" AURA lighting. That isn't the only appearance of LEDs though as you can see from the top image, and we'll look at in more detail on the next page, the vital LED indicators are also included in the TUF Armor, so you have an 'at a glance' idea of what's going on with your boot stage.

Storage is catered to well also, with the Sabertooth supporting M.2 drives alongside four USB 3.1 sockets. Just because you've chosen to go with AMD doesn't mean that you're forced to put up with slow devices.

It would be great if you could do some OCs with the 8320e

Some of those CPUs behave better than an 8350 when clocked higher (they require less volts)Quote

I would love you to get the FX-9590 8-Core beasts at 4.7 GHz stock. 10 power phases for 220w beast - Go man!

Good looking mainboard, but it's hard to get worked up about a 990FX chipset board when AMD's new stuff is just around the corner. Maybe it's a little late to the party?

I was using an FX-9590 CPU and Gigabyte 990FX Gaming G1 board recently. It was an extremely solid choice as I'm sure that this ASUS board is. It was very stable.
I gave the system to my son to use, and he loves it.Quote

Friend of mine would love this board as his older gen AMD Sabertooth board seems to have developed some very weird bugs.Quote
