Test Results - Stability Testing, Super PI and SiSoft Sandra

Product Acquired: Asus


For the Stability test I ran Orthos which is a dual Prime95 stress test, alongside dual Folding @ Home instances of the console client. To spice this up and really test the board I ran RTHDRIBL alongside this. This is a real test of the boards stability at stock and will show just how well it runs out of the box.

stress test failed
Pre-BIOS flash.

stress test passed
Post BIOS flash.

The Asus P5B-E Plus had a little problems with instability (cold boot) on the BIOS that it came with. After a quick flash and a few days checking it was all fixed so I ran the stability test. After the BIOS flash the P5B-E Plus managed to handle everything I threw at it over and above the call of duty, so it goes to show a little BIOS flash can do you good.

Mixed results in the stability testing..let's move onto some numbers.

Super PI 1 million and 32 million

Super PI is 100% the only choice for a quick bench of your top-end rig. It gives a quick and easy estimate of the relative speed of your CPU. The C2D's are now infamous for the their very fast PI times. The Asus is up against some stiff competition let's see how it goes.

The Super PI time is a little short on the all of the other boards apart from the Intel review sample board that we reviewed when Core2Duo was first out. This is a little surprising as the Abit boards do well here.

Super PI 32million

A longer run of the Super PI benchmark shows stability and speed in a quick convenient test.

Once again the time for the 32million run is slightly lower than the other boards.

SiSoft Sandra

Sisoft Sandra is a synthetic benchmark utility capable of reporting and benchmarking a wide range of system components. We ran the Processor and Memory suite to get some figures.

Processor Multimedia

Processor Arithmetic tests the raw power of the CPU and the processor multemedia tests the CPU in general multimedia tasks. There can be a slight difference shown between boards speedwise. Will the Asus be that little bit slower here?

The Asus keeps up with the other boards in the Arithmatic score and then steps ahead in the Multimedia score. It seems there's more to this board than meets the eye.

Memory Bandwidth

Core architecture has made the Intel platform perform much better than previous generations. SiSoft was always a benchmark that AMD dominated until Core came out. After some already strangely random results it will be interesting to see what happens here.

Here we see that the memory latency is pretty high compared to the other 775 boards and the bandwidth also a bit lower than other boards.

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??

Edit: Looks like a sweet arse board!Quote

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

As usual great review..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 :-)

"Thanks To Asus for the Review Sample"

02-01-2007, 03:38:20

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
