Asus P5N-T Deluxe 780i Motherboard


Input/Output Panel
The I/O panel on the P5N-T has a good range of outputs and caters for modern enthusiasts.
* PS/2 keyboard connector
* PS/2 mouse connector
* 1 x SP/DIF Optical digital audio output
* 1 x SP/DIF Coaxial digital output
* 1 x e-SATA ports
* 1 x Firewire ports
* 4 x USB ports
* 1 x RJ45 LAN Port
* 8 channel analogue sound output
IO panel
Not a bad selection, although again it's just not quite as good as the P5E3 Deluxe's outputs.
As is usual with Asus, the P5N-T Deluxe features a Phoenix BIOS. This is a little changed from the usual Intel Phoenix BIOS but everything you need is basically there ready to go. The BIOS is fairly simple to use and the board can be set up with minimal fuss, changing very little.
However, we're not interested in minimal setup, so let's take a look at what you can tweak.

x6 - x50
LTD Frequency
1x - 8x
FSB Frequency
200-800mhz (Keyable - 1mhz steps)

Asus offer a good range of adjustments with FSB, Multi and RAM options being very full and really nothing to complain about at all here.

A good array of voltage options gives the P5N-T a nice looking set of BIOS adjustments that are far beyond what most overclockers will be willing to put into their components. However, the options are there so Asus can be comended for that.

We check Asus latest 780i board

See how it doesQuote

15-01-2008, 14:32:40

Good review, shame about the board..

What a stupid idea to stick a IDE connector in front of the ATX connector though =/Quote

15-01-2008, 14:44:52

i was thinking that, terrible...

the chipset doesnt seem the best ever either...

Nvidia have failed every time after the Nforce 4 chipset..Quote

15-01-2008, 15:13:49

nForce 4 ftw!

Great review, although lacking board.Quote

15-01-2008, 15:15:42

Asus are writing a new BIOS after reading about the issues in this review so hopefully we can revisit it and perhaps it will show some better potential

Thanks for the comments Quote

15-01-2008, 16:29:36

Very nice review, but the board just under 680i I think, like Kempez said hope the new BIOS help.Quote

I love that... Thats seriously taking customers feedback into consideration!!

Nice one on the review anyway Matt.. Shame ya didn't have more to work with. Hope that 790i will be better.Quote

17-01-2008, 08:09:27

i am only waiting for the new mobo 780i to buy a new pc. Such a shame that asus didn't make it, else i would go and buy it now. Now i have to wait even longer. Hope better ones will come out soonQuote

17-01-2008, 08:12:36

Do you need SLI? The Intel X48's should be starting to make an appearance shortly, and I'm betting they'll provide better performance than the Nvidia 780i. However, it will be interesting to see if ASUS' new BIOS rectifies this board's issues.Quote

Do we have any idea on roughly when the X48's will be about.. Next month or two?Quote

17-01-2008, 09:26:18

Well Gigabyte has officially launched their X48 range (GA-X48T-DQ6, GA-X48-DQ6, GA-X48-DS5) so I can't imagine that it will be very long before ASUS and other manufacturers have them on the shelves.Quote

17-01-2008, 10:21:27

I was thinking about SLI, maybe buy an other 8800 GT when the price drops, so i was thinking about the 780i, or 790i maybe. It's painful to wait an other 15 days or so, to see the new stuff. And to buy a mobo that needs a bios update so soon doesn't seem like a good idea.Quote

17-01-2008, 17:36:26

Try a Striker II?Quote

17-01-2008, 19:11:43

Tbh 790i is becoming to appear more appealing to me. DDR3 is becoming much better value.

Check this out. DDR3, 2x 1gb rated at 1600mhz at "just" £140 is pre-ordered, getting much better value.

Pretty soon it'll be overtaking DDR2 withe the 790i's and X48 releases.Quote

17-01-2008, 20:44:02

only diff between 780i/790i and x38/x48 is the support of DDR3?

Then i would buy now.. No diff between DDR2/3, well not worth the costQuote

18-01-2008, 10:09:00

Well as you said it's one of the most expensive mobos till now. I think it's a bit too much to give for a mobo for me and also i don't see many other mobos in the market, so i think its better to wait maybe 15 more days and then deside...Quote

18-01-2008, 10:25:24

There is also the EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i SLI ATX that is out, and as i can see, users are more satisfied with this mobo. Maybe you will test it out later, but thanks to everyone for your help and thoughts ! Quote

19-01-2008, 10:19:23

Hi Guys, I am a complete newb to overclocking, I have built several systems but never delved into the Dark Art...! (Not with any success anyway!)

I bought this Mobo as I got fed up of waiting for the Striker II Formula to appear at scan despite having pre ordered it ages ago.

I am really struggling to get anywhere with it, I am quite pleased with the stock performance (compared to my ageing AMD FX 55, A8N Sli Deluxe combo) but would appreciate some tips / BOIS settings to help me get going. The best I have done so far is get a 10% increase with Asus' AI overclock setting in the BIOS if I try to adjust things manually it wont POST....


Great Site by the way.....

Cheers, Dave Warry.Quote

19-01-2008, 10:29:14

I'd suggest updating to the latest BIOS before you even try overclocking.

Set the CPU volts a little higher and al;so set the CPU VTT a little higherQuote

19-01-2008, 12:19:27

Thanks for the quick reply, I have updated to the latest BIOS (0502) and tweaked the voltages slightly but I am worried about frying stuff...! I am unsure what voltages are reasonable for the various settings. Is there a list of the voltages and tweaks that were used in the review of this board?

I will crack it, I just need to get over the initial fears....!

Cheers, D WQuote

Hey guys, Asus have released a new BIOS for the P5N-T Deluxe Nforce 780i. 0602.

I have used Asus, AI overclock option and got it up to 20% overclock with no problems this means a FSB of 320mhz and a core speed of 2.88ghz, I know that this is peanuts but previously the board wouldn't POST with an overclock of 10%...!

I now need to try adjusting the settings manually but could do with some advice on what voltage adjustments should be safe, or do I leave the voltage settings on "Auto"

It would be interesting to see what an expert Overclocker could get from this board with the new BIOS, seeing as the performance was "lacking" during its review...!

ANY advice would be very gratefully received....Cheers Guys

Remember overclocking is based on a chip per chip basis so no one person will get the exact same results

Anyone can become a good overclocker, it just takes patience and research mate and a lot of trying again.

Stay whithin safe CPU voltages (1.55v for air cooling for example) and watch the temps alla round Quote

21-01-2008, 14:30:44

Cheers Mate,

I will try and push the FSB up slowly, my target is 3.0ghz (unless I get hooked and start watercooling etc...!). My RAM is rated at 1000mhz so that shouldn't pose a problem.

You mentioned the CPU VTT voltage in your last reply, what would be a safe limit for this setting?

Cheers, D WQuote

21-01-2008, 15:06:03

Only bump up CPU VTT if you get stuck, do it in small incrementsQuote

24-01-2008, 13:07:25

Now that there is a new bios update for this mobo, did it become any better, and how about the overclocking, can it reach 3.0Ghz with the build in cooler ?Quote

24-01-2008, 15:35:06

I was waiting for the BIOS release to try again but due to review time constraints I've had to take it out.

I may get some time to try again but it won't be for a whileQuote

24-01-2008, 15:38:06

I managed to get it up to 3.375gig (FSB of 1500 in BIOS) and I could run 3Dmark 06 comfortably with a score of 19,448. However when I was playing stalker all maxed out it threw up BSOD's after about half an hour. I didn't try to push it any more than this and this was with my Thermaltake Big Typ 120 air cooler turned right down to silent levels. I am now running at 3.038gig (FSB 1350 in BIOS) with all the fans on Silent and it is Solid as a rock, (No problems playing Crysis last night for 3 hours, wife is at work...!, with all the settings at HIGH inc. AA & AF, Res 1600x1050 on 22" screen) 3Dmark score is still over 1700, So I personally am well impressed with the new BIOS it has helped me overcome my NewB overclocking fears....!

It would be good to see what an expert OC'er could do.....HINT HINT.....!

Cheers, DWQuote

I simply don't have time right now. If I get some (unlikely) I will update the reviewQuote

24-01-2008, 16:41:10

Thanks dood, you can only try :-)Quote

I think the benchmarks would be better, if a Nvidia card was used on a sli board. using an ati card makes no sense to me. very bad review.Quote

The fact that nvidia and ATI cards perform nigh on identically on any chipset not crossed your mind?

Also the ATI card was used on other boards review, so it there as a control. Using an 8800GT vs the X1950 pro and then saying the motherboard is fantastic for gaming isnt exactly a fair test is it.

And intel dont make graphics cards to test with intel chips.Quote

02-02-2008, 09:44:56

That`s the thing. There are a fair few reviewers out there that would switch out cards, cpus or memory, but where is the fairness in the comparison ? Or the consistancy really.

U have to try and keep the playing field for all the boards ur going to compare as even as possible. Components, to an extent don`t matter that much as long as they`re the same. A choice of decent proven stuff in this case I think, don`t want to overcomplicate things either and take ur eye of what ur really reviewing, which is the mobo.Quote

06-02-2008, 15:39:58

Not a bad review, definitely not a "very" bad review. There are many benchmarks that were taken that don't rely on video at all. I do agree to an extent about the video card, but mainly because it wasn't tested with a PCIe 2.0 card, which is what the board is supposed to be for.

I'm sure it's quite hard to keep everything accurate because, for instance, in a lot of benchmarks a 8800 with 256bit memory vs. one with a 345bit (or whatever it is) doesn't look like much now, but once games, etc. utilize it better, there will be a growing difference between the two. Same with the wolfdale vs. conroe, because the wolfdale is using new instructions, and once those are used in apps, there will be more of a difference.

Would really like to see a comparison between PCIe 2.0 and 1.0(1) performance on this site.Quote

17-02-2009, 05:50:39

I bought this board, sadly jumped into it without reading any reviews, i've been planning on overclocking my cpu for ages now, i've read many guides on overclocking (including the ones on here) but i'm still clueless, does anyone know this board well who could help me please?Quote

17-02-2009, 10:58:51

Probably best asking in the overclocking section m8.
