The Official P45 Asus P5Q Motherboard Thread

How do you control fans when connected to the motherboard? The AI suite doesn't seem to do anything, and I'm not going to sacrifice my 100% stable 3.6GHz overclock in order to run the EPU engine. I can't get speed fan to do anything but monitor. Changing settings does nothing, and they don't yet seem to have a profile for the P5Q series.

Suggestions anyone?

there's a speedfan beta out which he says has P5Q support now, BUT with the current version I can control my chassis fans by knocking one channel down to ~60% = 900rpm

However, i went through all the pain your going through and since then I uninstalled all the asus fan/ai software and just use Qfan in bios - it works great, changing fan rpms - it does not control my 3pin CPU fans, they are on max rpm no matter the temperature, but I have 3pin noctua fans connected in my chassis fan spots on mother board and Qfan actively changed these automatically according to whatever profile is seleceted in bios

note that I had to reboot a couple of times to get this to work after taking off the crap software - when I had it installed I could not get it to control the fans, only thru speedfan but honestly the bios Qfan works fine, and I run an overclock so the cpu fans on max is okay for me (these notcuas are very quiet anyway, most noise from GPU fans)

CPU fan can be controlled only if it is PWM fan. My Nexus 12cm PWM is at ~930 RPM all the time.
 
So why is this board better than the gigabyte EP45? I haven't read into it all that much but a friend of mine recommend this Asus board but I keep seeing alot who are overclocking using the gigabyte board.

I've had exceptional overclocking performance with mine. I'm running 100% stable at 3.6GHz with 1.49v. And temps never get scary, either. I love this board. Stability is excellent and build quality is fantastic for what you pay. A lot more solid caps than the $250 780i board I had. I have the PQ5 Pro.

Okay. I updated BIOS and fan control is working decent now, plus disabling QFan helped, but now with the 1004 BIOS all my temps are whacked. Right now AISuite says I'm idling at 9c. Har har har. CoreTemp still has me right on with mid 30's. What the crap happened to the board's monitoring capability with the new BIOS??
 
Thanks for the feedback guys. That was my main concern with buying this board. Just wanted to make sure I have access to all my SATA ports in case I would want to use em all. You guys help to solidify my decision. Thanks again! :)

One more picture from one of czech reviews :

Went to the 703 BIOS. Fan control still works, my overclock still works fine, but now temps are reported correctly. I called ASUS and they recommended I do that. Nice to talk to someone in plain English without an accent too (unlike when I called Gigabyte for support). Guess the 1004 has a few bugs for some boards. I am insanely loving the P5Q Pro. I have never had a board that's made me this happy, been this stable, while overclocking quad cores like it's an afterthought. Can't wait to throw in a second 4850 for some CF action.

My 780i is happily in my wife's home/office computer now. It's got a nice OC of 2.66 on my old E4500 @ 1.3v, 100% stable. At least it can overclock dual cores okay.
 
Never seen this before on a computer I built. P5Q Pro FTW ... only paid $120 for it with FS. Best mobo purchase ever.

I got similar results with my ep45-ds3r and my p5q-e. They're both good boards. I like the power & reset buttons on the p5q-e, but the gigabyte's BIOS basically never needs a manual cmos reset while the p5q does now and then. The differences are so small I think it really doesn't matter unless you're after something specific. The ep45-ds3r is slow to detect SATA disks in AHCI mode.

Yeah. So is my Gigabyte 780g board. My EVGA finds them fairly quick, but my P5Q pro finds them instantly. It boots up faster than any computer I've ever had. The login sound actually interrupts the start windows sound.
 
Alright, here's one for you guys...

Specs...
Asus P5Q standard, QX6850, 2x2GB Patriot Viper DDR2-1066, 9800 GTX+, 320x2 RAID 0

Alright, so I can install Vista 64, but when I get to the second reboot when you would normally come to the screen with the time/date select, user name select, all that, the system just hangs on the green loading bar. Running a full pc-check diagnostic over night. Any ideas?

The P5Q-E is an AWESOME board. I picked one up a couple weeks ago and been testing my OC. On my previous board (Gigabyte P35-DS3P), I needed about 1.456v BIOS vCore (no tool to measure idle/load in Windows) in order to be stable at 400x9. With this board, I'm stable at 1.4v vcore in BIOS (1.38 idle, 1.384 load in Windows XP) which amazed me! This is all with NO GTL tweaks, just vCore. Now, it may have been that my Gigabyte board had horrid vDroop, but I'm not so sure.

Will post updates once I start tweaking it more:)

Try using only one RAM stick and removing unnecessary drives & peripherals.

Go to BIOS and add DRAM voltage, but check first, how much youre RAM can handle.
 
I'm having a silent war with EVGA right now, but I think they will end up winning, and I'll be out 15% restocking fee.
I have a QX6850 (rogan you get yours from retail edge? :))
I HAD/HAVE a 750iFTW from EVGA. I should never have left Asus I guess, but was not having good luck with their A8N and P4P series.
Anyway, I'm thinking of getting back on the boat but would like to know if anyone can confirm that the P5Q series of boards (probably getting the Deluxe) has an unlocked multiplier in the MOBO Bios. I realize it's a dumb question but the 750iFTW, supposed enthusiast board, does not have the ability to push the multiplier past 9. Effectively making my QX6850 useless.
Also, contrary to [H] findings, it's OC'ing like sh*t for me.

Complete spec is:

CPU: Intel Core 2 Quad QX6850

Heat-Sink: Scythe Ninja Revision B. (NCIX doesn't seem to have it listed anymore. I think it's been replaced by the Scythe Ninja 2) + 2 Scythe Slip Stream Kaze Jyuni 120MM

Assembly: Thermalright Bolt-Thru Kit for LGA775 (SKU: 24833) http://www.ncix.com/products/index.php?sku=24833&vpn=BTK-LGA775R&manufacture=THERMALRIGHT

Case: Antec P182 ATX Black Mid Tower Case (SKU: 24122) http://www.ncix.com/products/index.php?sku=24122&vpn=P182&manufacture=ANTEC

All 3 Stock Fans turned to Medium or High and additional Scythe Slip-Stream installed at front of case.

PSU: Corsair TX750W (SKU: 26415) http://www.ncix.com/products/index.php?sku=26415&vpn=CMPSU-750TX&manufacture=CORSAIR

Well there it is. Too be honest I thought it was more than overkill. Where the CPU is positioned is right below and adjacent to the Antec Tri-Cool fans that came preinstalled. I added 2 more Slip Streams basically creating a 4-fan push-pull system. My system is definetly not quiet (even though it is a p182) but I wasn't worried about that immediately.

With the p5q series can I push the QX6850 to 4GHZ or maybe like 3.8GHZ? and have it run stable?

Thanks for the input
 
Just hooking up my exhaust fan (Thermaltake pos) to the board caused some instability issues. Hooked it back up to the psu and all was fine again. I prefer running the fans directly off the psu/controller anyway

EVGA 750i FTW not letting you run unlocked multi on an extreme?? Weird weird weird. And they call it an enthusiast board....

I the Asus BIOS on the P5Q (mine anyways) it goes all the way up to 60x on the multi, so if you have an unlocked processor you should be good to go. As far as hitting 4.0GHz or 3.8, depends on your cooling. The scythe is pretty good from what I've read, but you're going to push some decent volts to get a quad to hit 4.0GHz with any board. I did hit 4.0GHz windows vista stable with my Q6700, but it took insane voltages and put out some temps close to 70, even just running 2 or 3 threads of Prime 95, and I have a TRUE with an insane-good cooljag 120cfm fan.

Right now, though I'm running 3.6GHz 100% stable on only 1.5v, and temps never pass 62c even on full load with 4 cores running 4 threads of small fft's on prime95. My PQ5 pro is a beast, but I also lucked out with a good overclocker of a processor. If you combine a good P5Q board with a nice OC'able processor, 4.0 should be doable. Remember that 1.6v and up can damage your processor permanently.

This Asus board is leaps and bounds better than any nVidia chipset I've ever had. Way more stable, cooler northbridge and far less vdroop. That matter a lot when overclocking quads these days.

Not a big fan of this board's fan control.... Abit by far has the best ever in their uGuru. EPU is supposed to be good for fan control, but it won't even start if you have the slightest overclock. Ghey.
 
does any one have a link for P5Q-Pro BIOS settings / descriptions / explanations? also is the BIOS settings for the different versions of the P5Q (pro, deluxe, premium ect...) the same?

sorry never been on an intel before been on the socket 754 for years lol.. Q6600 G0 / P5Q-Pro coming in 2 days

edit: oh and whats the best BIOS version for the P5Q-Pro for oc'ing? and i see it comes with alot of software (express gate....AI tweakers..Probe...ect) are any of them worth installing?
 
express gate is awesome, can boot to internet to goto asus for files etc

I dont use any off the AI software or probe myself, use Qfan in bios and bios overclock

I'm giving drive expert "backup" raid1 a try just now. Running IDE mode as had problems with intel raid1
(it crapped out)

Asus keep updating the bios, check that forum for current information. I'm using 1201 now, 803 was good too.
That thread has "templates" for different CPUs; its easy to get 3.6 on q9450 and q6600 and there's settings to get you overclocked right away
 
Got my P5Q-E up and running with an Ultima 90 and a Q6600. 4GB Powerchip DDR2-800.
Bloody fast! Great board, CPU is now at 300*9 = 2.7GHz. No voltage tweaks.. yet :D

What kinda temps you seeing with the Ultima-90 and Q6600? And under what weather conditions... :p
 
One neat thing I just found out, when the power goes out and back on, the computer starts itself automatically. Used to be annoying to have the power go out quickly and right back on and I'd have to reboot it manually.

Using speedfan, does it not work if you have a profile selected in bios? I set it up and it seems to show my fans but when I back one down or up it doesn't do anything.
 
Just thought I'd post here and say that I have my e8400 stable at 4.0Ghz, was a piece of cake to get it stable. Once I've primed overnight I'm going to shoot for more :D

I found Qfan bios overrides speedfan and when switching Qfan off had to reboot twice to get speedfan to get control
 
Had bios glitch today, on restart system started recovering default bios saying it was corrupted. Only thing I had done different was use the drive expert as backup which was working, made a backup and it verfified it okay

Had to use the reset jumper when powered off, and reflashed to 1201

Dumped drive expert again. I only went back to it as although acronis was working for making backups it could not restore. I now think maybe express gate was stalling it when it tried to reboot. I've it (express gate) switched off now and will try again with acronis

I am still running in IDE mode, will try switching

Man I'm having some f-ups trying to get a 2 drive system working. First intel raid then drive expert crapping out. Anyone out there running either Raid1 or drive expert backup okay on SATA drives? and if so what bios?

thanks

What settings did you change? I want to OC mine but I dont know where to start (I have read thru the OC guide)
 
After being screwed over with my last mobo purchase I want to make sure this one is solid.
Anyone have any gripes or complaints?

I hear RAID (specifically RAID 10) is difficult with these boards?

I don't plan on using RAID 10, just RAID-0. I wasn't too impressed as the 750iFTW would have seek times of 13ms on my RAID-0 setup (WD640AAKS)

The only other thing I can think of, besides probably loosing some SATA ports due to GFX cards, is the location of capacitors near the CPU.

Has anyone had issues seating a large HSF on this board. Specifically a Scythe Ninja with 2-4 fans on it? I know one person on Newegg had a complaint about the capacitors location.

I'm so frustrated with my 750iFTW, that I'll probably just buy another HSF if necessary.

@SirKronan: Thanks for the info. Ideally all I should need to change to get 3.6GHZ will be the multiplier. If I change it from stock 9 to 11 that would give me 3.6Ghz without any other tweaks, besides Vcore, I think. Did you need to install the optional chipset fan onto this motherboard? The one on the 750iFTW is incredibly loud and annoying so I was hoping to avoid needing one.

Thanks
 
just got the P5Q-Pro

in order to run the memory in dual channel do they have to be in the memory slots closest to the cpu? (the yellow and black one)

I'm assuming you're referring to the P45 board, not the 750 board. I found that the absolute heaven of sweet spots for my Asus P5Q Pro is 450 with the 8x multi. It works slick. I know that's not really taking advantage of the extreme's higher multi, but it really flies for me with good voltages and good temps. Stability is top notch. I would suggest trying that. I think any of the Asus P5Q boards can handle 450 FSB in their sleep. With a few exceptions most reviews and user experiences I've read through (and I've read through a LOT of them before I bought my own P5Q) have been overwhelmingly positive. I can't think of a better board to push your extreme. I was able to get my Q6700 4.0GHz Vista stable thanks to the 10x multi. Worth every penny to me to finally have hit 4.0GHz in my lifetime on air cooling only, even though I don't run it 24/7. This board has been wonderful.

Which P5Q are you getting? I had a spare small SATA laptop hard drive on hand, so I use it for express gate. The P5Q pro hits the sweet spot for me performance/features/price wise. Still has E-Sata and firewire. Won't base my primary workstation on a system without those two features. has plenty of USB and SATA ports on board too.

Luckily for me NCIX is offering me a full refund for the 750iFTL :)
I decided to go with the P5Q Deluxe. I know it's a bit more expensive but it's similar to the cost of the 750i, and I'd feel bad about taking money from these guys (NCIX) after they completely waived the restocking fee, due to EVGA's stupidity

I'd love to run 4.0GHZ stable 24/7 but I'd be happy with 3.6-3.8 which shouldn't be too hard. Do you think I'll have problems seating the Scythe Ninja? (it has 2 fans on it) [close proximity to capacitors]?

Some of the reviews I've read stated that the P5Q-E and P5Q Deluxe have slightly better layouts for cooling the north and southbridge. Hopefully I won't need to use the included chipset fan. I'm really happy about the extra Sata ports (750i had 4!) and I may actually use the Dual Gigabit connection through a cross wired connection to my old pc.

I should have everything bought and installed by tomorrow, will post in when I do.

Thanks Kronan and everyone else.

The Ninja should work fine. All three of the P5Q revisions I studied looked to have good room for a decent sized CPU cooler without bumping into anything. I have the TRUE with one huge fan on one side, and when I put in my second 4850 for CF I'm going to reseat my CPU (I think I bumped it a tad, as temps have gone up slightly higher than normal on full load of late) and put a pull fan on the opposite side. I already have my second set of brackets.I'm just wondering what to connect it to since Asus fan control sux sooooo bad.

The extra SATA ports come in handy! I am using six of mine, and will use a 7th for E-Sata later when I add some external storage.

The cooling is better on the Deluxe and E versions of the PQ5 pro. It was almost enough to make me spend the extra $30, but I spent it on an extra SATA drive instead, so all my drives are now SATA. Well worth it to me. I'm sure the airflow improvements gained by going SATA instead of parallel will likely almost make up for the better cooling in my situation, based on fan layout of my case.

You're in great shape though. You will likely love the P5Q Deluxe. It even has the SSD Express gate, I believe. SUPER convenient. 3.6-3.8 should be no problem. What are you using for your thermal compound?
 
What kinda temps you seeing with the Ultima-90 and Q6600? And under what weather conditions... :p

~35 at idle, ~50 at load, with a 3-4 degree delta across cores. Open side panel, 92mm Panaflo, and ~28-30 degree ambients.
Too high?
 
guys my P5Q-Pro came with this weird transparent water marks/stain all over the entire back of the mobo (i don't know if its water or some chemical). you know when water dries up on something it leaves leaves a bubble like pattern stain. but it is not any where on the front of the mobo. any one know what it could be?

does anyone else have this on the back of there P5Q-Pro....should i RMA it? i'm afraid if i turn it on it might be bridging all those solder points on the back :|

That is weird. Mine came clean as a whistle. Was it in a bag? Did you buy it open box, maybe? If not, then it shouldn't have anything on it.
