Our Score:


Getting onto PCI slots we have two 16x PCIe slots with plenty of breathing space between them, three 1x PCIe slots and two of the old PCI variety for those who want to install older cards. That's certainly plenty for most users, though a single dual-slot graphics card will cover one of the 1x PCIe slots while a second would cover one of the PCI slots. Just as with the clever memory retention mechanism, another nice touch here is that the latches for holding in the graphics card(s) have been modified to be easier to reach with a card installed.

It should be noted that despite offering both CrossFire and SLI compatibility, as with other P55-based motherboards the Sabertooth 55i only supports eight lanes per channel when using dual graphics cards, so if you want every last drop of performance out of your dual video cards you're still better off with an X58-based system.

Getting onto the Sabertooth's rear I/O connectivity, we have PS2 connectors for mouse and keyboard. While the latter arguably still makes sense for BIOS problems, there is simply no reason to still have PS2 mouse compatibility on a modern enthusiast motherboard. Eight USB2 ports should be plenty though, especially since a bracket is included with a further two ports, still leaving two USB headers (for four ports) free on the motherboard. There's one eSATA connection on the backplate (just above a FireWire port) and another on the bracket.

For audio we have a single optical digital output (a bit stingy considering most motherboards in this class offer both optical and co-axial) plus six analogue jacks that can output DTS or up to 9.1(!) surround sound from the board's VIA VT2020 10-channel audio chipset - definitely a step up from most. Finally a single Gigabit Ethernet port takes care of networking.

As one would expect from a manufacturer who's been in the game as long as Asus, the BIOS offers more options than you can shake a stick at yet is logically laid out (one slight exception being that the Hardware Monitor is found under Power).

The two most interesting menus aside from the usual suspects are A.i. Tweaker and Tools. As the name implies, A.i. Tweaker includes 'intelligent' overclocking options, though you're better off using manual settings for the best overclock. Under Tools you'll find up to eight fully-configurable overclocking profiles, which can be saved to or loaded from either the BIOS or external storage.

It would help if you actually mentioned the warranty in these articles. That's the one thing missing from your otherwise enjoyable site.

...motherboards tend to last to survive far beyond their useful lifespan. Not in my experience with Asus they don't. I had 2 same boards fail on me with the same fault and because you can't RMA direct to Asus, I was stuck with the retailers refusal to do anything about it. I haven't bought Scan or Asus since. Get an EVGA board, 10 year warranty and direct RMA. You know it's worth it :)

I've been working in a big electronics store for the last 7 years and I've seen faulty Asus motherboards only couple of times. And there was absolutely no problem to get a replacement from the distributor. And you can get direct RMA here in Poland - all you need is to fill in the form on the Asus website. My current PC is based on an Asus MB, as 2 previous PC's before it.

Indeed, kind of forgot to mention that, apologies. Unfortunately it's just the standard 3years as far as I'm aware.

I must admit that I've used an Asus board in one of my previous PCs and like with S_p_i_d_e_r it lasted as long as the rest of the machine did.

BTW, we usually mention warranties on, for example, laptops in the feature table.

Our current warranty is 3 years, with an estimated 5 days turnaround time if you purchase from an ASUS authorised reseller.

I'm sorry for the problems you've experienced in the past. Our RMA service has been changed quite radically in the last 3 months to help improve the consumers experience of ASUS.

well intel has managed to confuse me, so you can use the i7 and i5 in the P55 but only the i7 in the X58? I thought the i7 and i5 were going to be seperate lines that you choose one and if you wanted the other you had to buy a new motherboard aswell

That's nice to read ASUS UK, but it's once bitten twice shy for me. Unless you're saying there IS now a direct RMA procedure? I bought Asus for at least 10 years prior to this experience. (back when the pcchips website had a wooden veneer background image and you had to try your best to find drivers for various chipsets using FCC codes and Acer was still ALi :D)

I felt at the time, that had I been able to convince the retailer to ask Asus on my behalf, that Asus would have seen straight away that it was a legitimate claim. The retailer refused to do that. As I had no direct recourse with Asus, I decided to take my money elsewhere.

PS: thanks Ardjuna; warranty details are right up there on my list when looking for new hardware.

I am not an Asus fan but it makes decent products. I give a big thumbs up for this motherboard and Asus. Good and different kind of effort.
