Asus P5B-E Plus socket 775 Motherboard p965

I/O and BIOS

I/O Options

There's quite a bit on the back panel of the P5B-E Plus, which is a great sign for those with PS2 keyboards and mice and conversely e-SATA for those who want some great external IO options.

As you can see we have a decent list of connectors:

* 1 x PS/2 Mouse Port
* 1 x PS/2 Keyboard Port
* 1 x Digital Coax Out
* 1 x Digital Optical Out
* 1 x Firewire
* 1 x e-SATA
* 5.1 Sound Panel
* 4 x USB 2.0 connectors
* 1 x LAN
* 1 x Serial Port

There could have been an extra LAN port perhaps and maybe a USB port or two, but in all honesty this board isn't a high end board so I can forgive Asus those little misses.

The BIOS on the Asus is the American Megatrends BIOS commonly used in a lot of Asus motherboards.

asus p5b-e plus main bios

I don't find this BIOS as easy to get around as a lot of BIOS, but it certainly has a plethora of options and once you're used to where things are you can get around it nicely.

asus p5b-e plus overclocking

The "Advanced" part of the BIOS enables you to see some of the overclocking options. Just this front page shows how many options you have at your fingertips with adjustments for a plethora of voltage adjustments. Here's a couple:

asus p5b-e plus cpu volts asus p5b-e plus ddr volts

asus p5b-e plus nb volts

With CPU volts adjustable from 1.3v to 1.7v (in 0.0125 increments), DDR voltage from 1.8v to 2.45v, NorthBridge volts going from 1.25v to 1.65v and FSB from 1.2v to 1.45v there's a whole load of voltage regulation you can use. Add to that a good range of ICH and SouthBridge voltage adjustment and I'm pretty impressed at the range that the board lets you adjust.

Moving on to FSB adjustment the P5B-E plus lets you hike it from stock all the way up to a rather ambitious 650 FSB. Memory can be divided as necessary into 4 sections (and it auto-previews what effect the divider will have on the final RAM speed when adjusted with the FSB). Also present is a function for adjusting the CPU multiplier, as well as some quite extensive RAM tweaking.

asus p5b-e plus FSB asus p5b-e plus cpu ratio

asus p5b-e plus ram timings

The RAM menu has more timings than I think is absolutely necessary and I haven't had time to really delve into how each of the other settings will effect the overclock, but having them there is a good thing.

There's a couple of trick little features Asus piles into the BIOS like Asus OC profile and EZ update but these are pretty trivial and the BIOS in general is pretty solid.

All in all the IO options are pretty great for a board in this price bracket and the BIOS has a load of features and tweaks that will be appreciated by those enthusiasts saving a little cash from the high-end, but still wanting a full-featured board.

Let's see how the P5B Deluxe's little brother got on then shall we?

I think the page 5 32million Super Pi test graph is wrong? 19 sec 32mil test??

Good board but I'm glad I didn't purchase it. 2.1v vDimm would have made me sell it the minute I booted it up.

Anyway, extremely thorough review Kemp. Looks great!Quote

2.4vDIMM mate

But ye tis a nice boardQuote

Hey Kemp, I just thought I'd let you know about a couple of typos I think I found under the Introduction section on page 1

Am gonna read the whole review tonight looks like a good read btw!Quote

Oh? I thought you set max. values in BIOS when u took screenies.

Some P5B's (well, some revisions) were known to max out at 2.1v also.

2.4 is still slightly low, but safe for D9. Above 2.4, heck, even 2.4v for D9 will kill it slowly.Quote

29-12-2006, 02:54:22

Ye it's 2.45v which isn't too bad, though very slightly low I spose.

@ spirtd: Changed the they've, but I think have looks fine to me Quote

Nice review... just wanted to add Matthew, that and the bottom of this page, you have included direct link to :-)

Oops, dunno what I was doing there


20-05-2007, 03:55:12

Hey Kemp is this the same as the Asus P5B Plus on their website?

Why the P5B E?Quote

20-05-2007, 11:33:26

That's what the box (and mobo) said mate Quote

20-05-2007, 11:55:48

An amazing read thanks! Quote

Another Good review, and i gotta say i really like my P5B-E, i bought it to save a bit of money on bits of the P5B-deluxe that i didn't need, liek the Wifi and dual LAN etcand im pleased as it's performed great, overclocks well and only cost £75 Quote

Aye it is indeed a good deal mobo Quote

28-08-2007, 14:36:11

I've just realised, mine is just the P5B-E not the P5B-E PLUS. Is there a difference between the two? Quote

28-08-2007, 14:50:03

Not much of a muchness I don't think, is yours black?Quote

28-08-2007, 14:51:33

Yellow Quote

28-08-2007, 14:52:26

Ye this ones black and has a few more SATA ports I think

Did you read the review and look at the pics? lol Quote

29-08-2007, 06:04:00

Yeah i read it lol

I just assumed because the box and board were different colours that i had a later/earlier revision or you hada 'review' sample, only when i checked my box i saw it ha no PLUS. Quote

15-03-2008, 06:20:56

Does anyone know if this board will support the penryns that are out soon?Quote

15-03-2008, 07:48:22

I would imagine so with a BIOS update, but don't expect the longevity to cover Nehalem procs (LGA1366). All you need do is head to the manufacturers website to find the answer, which I have already done for you here
