Asus P6T non deluxe ?


Aug 5, 2004
I am planning on building myself an i7 system in next couple of weeks. What i found surprising so far is how few mobos currently exist for i7. Is the non-deluxe p6t considered a good mobo for stability and decent overclocking? I've been an asus user for years and dont particularly want to switch to anything else.

Or are there currently better alternatives to asus mobos? I am lookign for a simple board that performs well and doesnt have any of that flashy rubbish all over it.
I just bought a P6T for expressly those reasons. After going with top-of-the-line motherboards for my past 4 rigs, I've come to realize all those extra sata ports, large cooling solutions and expansion slots just end up sitting there, un-used. I'm not a competive OC-er either and will be happy to push my 920 to 3.6Ghz which I'm sure this board will do with ease. This board has everything I need and more and will be a good home for my 4870 X2s. Now if I could just get all that money back I wasted on those "extreme" motherboards...

I find it kind of "funny" that there are hardly any reviews of this board yet; strange how the top-end stuff always makes their way to reviewers first. I'll post a short review as soon as I'm up and running.
Also with the non-deluxe P6T you'll be able to use a S775 HSF on it because it has both sets of holes.

Yep, that was another reason I got the P6T. There's just no way I'm throwing out a perfectly good waterblock. I was looking at the Foxconn Bloodrage - the only other board on the market with LGA775 holes - but again, I didn't want to spend $300+ for stuff I'd never use.
I also chose the P6T. So far it's been solid. One of the cheapest boards that supports 3 way SLI as well. Only issue that started to crop up is that it sometimes won't come out of sleep mode. I haven't figured that issue out yet. Other than that though, it's a great board and solid overclocker.
Only reason I am tempted to go with the deluxe over the regular is I don't own any premium heatsinks yet, more usb port, sas controller can be disabled and allow you to run sata, and 1 extra gigabit lan to dixie chain pcs. Main reason is 8 more capacitors. The regular is not bad by any means and should perform identically to the deluxe.
MunchMouth. I'm not having any issues whatsoever. This thing lives up to my epectations with ASUS. I've had better luck with ASUS than even DFI
well when it fires up the first time and has been easy to overclock, and I was able to retain my waterblock without any mods? its great. I used it with crossfired 4850's with no problems.
I also have the P6T non-deluxe. I went into the BIOS and set Bclk=166 and DDR3-1660 and left everything else alone for now. It's prime95 stable and the hottest core was 73°C after 12 hours of that. (vigor monsoon 3 HSF)

Is that at stock voltage?

Anyone had luck getting to 4ghz on their 920? :)
Im not running HT and I'm getting about 36c idle and at max 65 load. and it's the only thing in my loop.... I think I need a 3x120 rad. the 2x120 I dont think is powerful enough anymore
A little warm for water... thanks for the info.

I'm looking at air cooling, I should have noticed your sig. :eek::)
ignore that it's 1.35v on qpi dram and I'm trying 21x192 and in at 35c idle and loading on prime 95 no more than 60. I think I need a better block and rad still though

The BIOS adjusts the voltage by default when you overclock. I booted at some higher Bclks but temperatures immediately hit the 90°C range in Prime95 b/c the CPU voltage was up around 1.4. I'll start playing with the voltages manually, but right now it's not high on my priority list as I just wanted 3.5GHz and got it easily. :)

Also I can confirm my board came with the 0202 BIOS as well and didn't need a reflash.
your results with your boards sound good...... Hummmm I need to decide what I am going to get...
Update to my earlier post, I set the core to 1.225V at Bclk=166, DRAM=DDR3-1664MHz, 9-8-8-24 timings on OCZ Gold RAM rated for 8-8-8-24 @ 1600MHz.
8-8-8-24 booted at 166 but failed at Bclk=167 so I doubt it'd be stable.

At CPU=1.3V, 9-9-9-24 RAM, Speedstep/Turbo disabled:
4GHz (200 x 20) boots but BSODs on login.
3.8GHz (200 x 19 and 190 x 20) is Prime95 stable for a few minutes until BSOD. Max core temp was around 80C, so I have a bit more voltage headroom.

More tweaking is in order, but I'll be a bit slow. I haven't OC'd anything since the Tbird days... and before that, the Celeron 300A's. :eek:
195 x 20 = 3.9 GHz

CPU = 1.35V
Uncore = 1.40V (this is listed as "QPI/DRAM Voltage" in the P6T BIOS)
DRAM Bus Voltage = 1.64V

Prime95 stable for 30 minutes so far. Core median temperature is 88C, hottest core is 92C .

My RAM seems to be real picky about CAS latency. It'll do 8-8-8-24 at 1600MHz (which is what it's rated to do), and not 1MHz more. At 1601+, 9-8-8-24 is necessary.

At Bclk=195, my DDR clock is 1540-ish so I stick with 8-8-8-24 for now.

I'm having trouble getting my uncore (QPI link) running fast. It's usually ~4GHz at modest overclocks but the AI overclocker drops it significantly at this speed. My attempts to bump it up (so far) won't POST.
I hit a brick wall at 4GHz. Can't get it stable @ spec voltages & temperatures. Tried a few different things... meh, temperatures were too high anyway and I want something 24x7 stable.

3.9GHz was mostly stable. (Prime95 did BSOD after about 3 hours, but a little more voltage would fix that).

Right now I'm looking for the lowest voltages needed for 3.8. Prime95 has been running in the background for over an hour now with these settings:

1.60Vdram (DDR3-1520MHz, 8-8-8-24)
CPU differential signaling voltage = 900mV
Spread Spectrum options = disabled

All the cores are in the 70°C range. Potential long-term 24x7 overclock?
The next thing I'll try is lowering voltages until it crashes. If I can get the temps even lower that'd be great.

Another P6T user here.

Been running at 4Ghz @ 1.4v for two weeks now with this board and absolutely no trouble.

191 x 21 and 211 x 19 both work perfectly. 200 x 20 required a bit more vcore.

Didn't have to set any voltages too high (VTT and vQPI both within Intel specs)

It's a very solid board, and it allows 3-way SLI which even the Deluxe doesn't. (not that i'd ever use it)

My only complaint is the slow release of new bios, but apart from the S3 sleep issue (also present in other Asus, EVGA and Gigabytes board) there is no problem at all.

Easiest overclock ever.
i hit 4.0ghz stabel 200x20 with 1.35v 1.96 PLL and 1.66 dram and 800mv.

I also have a regular P6T and I love it. Great board for the price

I tried 211x19 and it was unstable, couldnt even do superPI

I can run Prime 95 8 thread, and it will go into the 80's, but thats it. I figure its stable, and nothing I do will ever get temps that high. While playing games i never see over 60c.
1.35v only gets me to 3.9GHz 195x20 on my proc. :\ Temps are around 90c w/ steady Prime95 (x8 threads)

3.48GHz 166x21 (turbostep) runs fine at 1.2v core w/ Vqpi=1.4. (DDR1666 puts QPI link near 4GHz) Core temps in the 60's.

Right now I'm testing 3.8GHz, 190x20 @ 1.275 core, 1.35 QPI, 2.0 PLL, 1.62 DDR (1520MHz 8-8-8-24), All core temps are in the 70's and Prime95 has been running for a while. Hope it sticks, that'd be one nice overclock for games... as you said, nothing you ever do will approach the temps of an 8-threaded stability test.

FWIW... my processor is from batch 3839A.
The most efficient 3.8GHz settings I've found to be stable (so far?):

screenshot - bios pics: speeds/voltages - extra settings - dram timings (i put dots next to the changed settings)

The hottest core went over 80c because the case ambient rose to 30c (normally 25c) as the room warmed up. :D

The hottest core is in the low/mid 50's in Crysis. Idling right now at 40/38/42/36c, case ambient=24c.

In conclusion.....3.8GHz on air, 24x7 stable for life? It's more likely than I thought!

UPDATE: I bumped the DRAM voltage back up to 1.66V and got my 1600@CAS8 RAM running 1540 @ 7-7-7-20! It's still Prime95 stable so far. :D

Good old ASUS, bro. Remember when we first installed the P5B deluxe wifi in the basement rig? Turned the thing on, set the FSB to 515, and watched that little e6550 come to life at 3.6GHz. And to think the damn thing is still going strong.
yeah one of the reasons I picked ASUS on this build. the DFI was a good experiment, but ASUS is fire and forget mostly.
I have my rig on order should be here this week. It'll be a real improvement. I've been putting off upgrading for sometime due to buying a house and having a kid. I'l be going from a Athlon64 4000+ to this 920 and asus p6t board. As I was planning my upgrade, I originally was going to go with the gigabyte ud3 board. but then I thought about all the old pcs I've seen as a computer tech (14yrs), and 95% of the time someone brings me something all caked in dust and hasn't been open since it was built, it has an Asus board in it. They seem to really exude quality and ruggedness. This will be my first Asus board and it's good to hear so many good reviews. Really excited for it to arrive.
Have been up and running for a day now. This board is quality.

A couple hiccups on the install:

My Gigabyte waterblock fit perfectly in the LGA775 holes (775-compatibility = awesome) Only problem was the bacl mounting plate was raised a little by the board's silver plate on the back of the socket. This made judging pressure when tightening the blocks spring-screws a difficult. I must have gotten a little overzealous and tightened too much - the board wouldn't post. This threw me for a loop because the board lights would appear and the fans would go full-blast, but no beeps or video signal. Apparently there is a fail-safe on i7's that won't allow the CPU to work if too much pressure (+800g/inch) is applied to the heatpad. Luckily, no harm done and the board posted once I loosened the screws a bit. Waterblock is working great now.

Prior to putting everything together, I was concerned about RAM compatibility since I read this board was picky and the Super Talent DDR3 1600 I had wasn't listed as approved for the P6T. No problems here though and have even been able to get it up to 1805. Bios is laid out nicely extremly easy to find the essential settings. Even better, the board recognized my RAID 0 array from my old Abit board and booted right to Windows! Just have to call to (re)activate now... Over all, the easiest Mobo/CPU/RAM install I've encountered.

One negative point on the layout (at least for me): the two x16 PCI-E slots are right next to each other with very little room between them. This means if you are running 2x dual-slot cards like I am, they are sandwiched right next to each other. I think a better design would have been to have the x4 PCI-E between the two x16 slots (x16-x4-x16), or place the one PCI slot between the two x16 slots. Not a biggie in any case (my cards seem just as cool as in my old board), and will be a non-issue if you're not running Crossfire or SLI.

Another annoying design choice is the lack of a CMOS clear button. Unless I'm missing something, you need to switch a jumper to clear CMOS. I haven't had to toy with jumpers since my old A8N :)

Now for the fun stuff... I'm running at 3.9ghz (195x20) all stable with 5 hours of Orthos, 2 hours Prime, several hours of Crysis and FO3 so far. Temps are 38c idle, 64c load - well within reason for Nehalem. All I did was increase the BCLK - easiest OC ever! Going to go for 4ghz then see how far I can back off on vcore.

Update: I'm at 4ghz (200x20; DDR31603) now, all stable. 3 hours of Orthos, 10 runs of SuperPi. Temps at 45c idle/69c load. Should I go higher...?:confused:
Now that I've had the board a while, I've noticed a few minor glitches. Is it just me, or do other boards have these problems?:

Adjusting the QPI link speed in the BIOS has no effect. As Bclk is increased, QPI will keep increasing to 4GHz before the multiplier is adjusted down a notch.

The orange DriveXpert (JMicron-controlled) SATA ports don't return correct S.M.A.R.T. data from the drives. So HDs should be plugged into the red (Intel-controlled) ports and not the orange ones. FWIW, I was able to move my C: drive cable from the JMicron controller to Intel controller and it didn't affect booting at all in Win7.

Can any other P6T owners confirm these issues?
