Asus P6T Deluxe X58 OC Palm Edition Motherboard



Skipping past the usual plethora of BIOS options we had straight for the business end of the BIOS, the AI Tweaker section. Those used to Skt775 will notice an option that is no longer present on the P6T Deluxe and that's the FSB (Front Side Bus) feature. That's because this has, in its most basic form, been replaced by what Asus calls Base Clock. Using a large multiplier and small clock may seem like suicide for performance freaks looking to squeeze every last drop of performance out of their rigs but there is a method to Intel's madness as this doesn't seem to have affected the performance as we shall see in the benchmarking section of the review.
AI Tuner CPU Ratio

Notice when the CPU ratio (maximum of 20 on the i7 920) is changed from AUTO to 20, the Speedstep and more importantly, the 'Turbo Mode Tech' options disappear? The Turbomode Tech works by altering the CPU multiplier past its maximum setting of 20 up to 21 when the CPU is put under load, working to the opposite of Speedstep. So in effect when the CPU is under load, the CPU is overclocked by the multi which is great news for those who don't wish to overclock the BCLK (Base Clock) frequency but still desire that extra boost when it is needed most.
Memory Dividers Vclk frequency

QPI Link DRAM Timings 1
Remember how I said that the FSB is no more? Well that's not all, the chipset strap has also died a death and has been replaced by settings unfamiliar to those who have become accustomed to skt775 settings. The UCLK Frequency option controls the speed of the Uncore clock, which in turn controls the bandwidth for the link between the on die memory controller and therefore the DDR3 modules themselves. This link speed is dependent of the DRAM memory dividers (frequency) as shown above. The QPI (Quick Path Interconnect) Link Data are similar in operation to Hyper transport bus found on previous Intel motherboards and are directly linked to the input of the Bclk (Base Clock) setting. Got that, OK let's move on.

Memory Timings are still here thank goodness and the Asus P6T Deluxe has these settings in abundance with every timing you could possibly wish for. For simplicity, only the basic settings were adjusted for this review with the ram modules set at their stock ratings of 8-8-8-24.
Timings 2 Voltage (Crazy)
Above left we see the remainder of the DRAM timings and above right is the scary part of the BIOS. Here you can see the maximum available voltages which anyone would be crazy to use on their shiny new i7 CPU's (no I didn't actually set these!). The Vcore can also be pushed even higher (2.1v!) should you feel the need but this can only be done by switching the on board CPU Over voltage jumper. There are plenty of GTL reference voltages to play around with too once you have found you maximum overclock which may help to help stabilise the overclocked settings. Also in-situ is the Loadline Calibration tool which on testing worked very well with Vdroop suffering only ever so slightly (0.02v).
VoltagesHardware Monitor
Rounding off the BIOS section, we come to the Hardware monitoring section. While this section is useful on most motherboards, I somehow felt it was made redundant by the OC Palm monitoring software, not that either should be trusted 100% anyway and should only really be used as a guide.

So then, a very complete if somewhat different BIOS to what Core2 users will be familiar with. Rest assured though, it is pretty easy to pick up once you get your head around the new settings. It always helps when you have such a well laid out BIOS such as the one Asus have provided with the P6T Deluxe.

Let's take a look at how the board actually performs with a few tweaks of the new settings available..

Nice review mate..

Hopefully now that one is nailed down it'll be easier to review when more boards come.

Was that the maximum stable overclock you could get or were you just happy to get there and call it a day?Quote

Great review, mate!

I was very astonished, that the s775 sometimes can match or even overrun the new socket. Nevertheless the new platform is a great performer, but I don't think that the time has come to upgrade to it, maybe next year . I would love to see how the new i7 performs against the new phenom 2 that are coming, because there are great things you hear about the overclocking performance of the new AMD's. Hope you will get a phenom 2 sample fast and compare these two.

And again, congrats for the great review.

Have a nice day.Quote

It`s doing a decent job. Nothing proud of a new socket tho.

I can see that the areas it does exel in are more than likely down to the tri-channel over dual channel.

I can't recommend them on this showing, but I still see this as part of the 1st round of mobos. The fact that it holds it`s own, with the exception of older graphic benchmarkers which dont mean much, means that whatever is to come should be that much better.

It`s a great review, like to see the Intel 4 Series ICH10R up against it tho as opposed to nVidia.Quote

Cheers for the feedback as ever guys.

The overclock was the max possible at the time of review. For whatever reason it wouldn't budge much over 200 but the rumours are that using a lower multi and higher Bclk helps, sadly this info came too late but rest assured, I will update when I get to test the mobo again as it looks like it could be the base for our new i7 test rigs.

We chose to pitch it against the NVidia chipset as it is the only chipset where we could have DDR3 aswell as having the capability to underclock the DDR3 to 1600mhz to best match the 1600 Corsair so comparisons could be made with dual vs triple channel ram. Intel chipsets would mean messing with the FSB and multi's of the QX9770 which inevitably would result in an unfair stock vs stock comparison of the CPU's.

It's always going to be hard reviewing a product with no legitimate comparative product. I could have copped out and just reviewed the P6T against itself, stock vs overclocked which is the norm but I thought everyone would have appreciated some results people they could relate to. Not many folk have the QX9770 granted, but it makes interesting reading having the top skt775 vs the entry i7, at least I hope it does.

Keep your eyes peeled for the Gigabyte EX58-UD5 review coming very soon .Quote

Cracking review...I'm still holding off for a whilst though...i'm hoping the phenom II's may push the price down...but its very impressive for a new socket utilising new tech...especially when you look at the entry/high end level does show that the price is warranted...but lets hope AMD step in the ring a bit beefier then last time...Quote
