The Official P45 Asus P5Q Motherboard Thread

i disabled them both before i installed vista...also disabled express gate..... i am getting this weird thing where my mouse freezes and stutters...which wasnt happening yesterday though. kinda annoying not sure what it is

also disabled LLC (load line calibration) even though it comes set to auto.. disabled it

Okay, then in BIOS set your multiplier to 9 (I assume that is max for your chip) from auto.
 
EPU 6 is the energy saving unit..its job is to save electricity..thats why it downclocks the multiplier. Im still running stock with the e8400 on auto, but when u put AI Overclock tuner to manual in bios..to set memory timings all the EPU functions stop working and the e8400 runs full speed all the time. So it looks like the energy saving feature turns out to be of no use.

The motherboard has worked flawless the entire time ive had it running, good stuff if your not trying to run SLI. Tightened my memory timings up to 5-5-5-12 @ 2.05v Mushkin redline ascents rock and stay nice and cool....mb temps are 40-41 c and the cpu is 45c! just 2 80mm fans
 
Hey guys, I recently got my P5Q-E delivered and I have her up and running right now:)
Couple questions...I just read the post above about the EPU engine and not running if you set AI Tuning to "manual". Is there any way to get around this?
Also, I just felt the Southbridge (the one with the EPU heatsink) and it's really really hot. So mucht hat I cannot hold my finger there for more than 2-3 seconds for fear of getting burned:eek: Is this normal or can I fix it somehow? My P35-DS3P recently had a bad SATA controller and so I upgraded to this. I really don't want to send back ANOTHER motherboard because of a messed up southbridge.

Thanks!

Also i noticed after my install that i should use AHCI mode before installing vista? I didn't just used IDE mode that the board came preset to. I cant figure out what AHCI is and what the difference is ...can someone explain this to me...and if there would be any benefit to reinstall vista with it in AHCI mode? thanks any input is appreciated

I made a post earlier about how to switch without reinstalling windows:
http://www.hardforum.com/showpost.php?p=1032814591&postcount=322

I also updated my bios to 803 since then, and there is no longer any slow-down in my boot-up. It now boots just as fast in AHCI as it did in IDE.
 
can someone recommend me a good 2x2GB set of ram that will let me overclock my E8400 to 4ghz and beyond? I though G-skill , OCZ preform better than corsair with this board. What are you using?

is PC2-8000 enough or do I need PC2- 8500?
 
I would say ocz pc8500 hpc reapers,they clock to 1100+ and are reliable.

Which MB?
 
I have the P5Q-e and only wanted 4GHz out of my e8400. I picked up this 2x2 set of G.skill:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231122

I did 445x9 at first to get to 4GHz and didn't have to mess with any of the ram timings/voltages. I now have my chip at 500x8, so my ram is running at 1000mhz. I have my timings at 5-5-5-16 and vdimm 2.0v, perfectly stable. Can't go wrong for $79.99 I don't think they'll take anything much higher than 500fsb, but how high do you wanna go on your e8400?
 
Either would be fine, but since PC8500 is much more common you will probably have better luck finding a reasonably priced good quality set there. Both will easily handle up to 500+ FSB, running 1:1 of course.

I think you are mistaken. Its speedstep dropping your mux. EPU 6 works great for me. I have it all tuned up and with a simple press of a button, I can OC to 3.2GHz or UC to 1.7GHZ!

Sometimes this sucks for watching movies bc the cpu is a little underpowered even when u put the epu6 to turbo mode.
Click to expand...

I suspect your problem is not with your CPU clocking, I would look into the GFX card or HDD on this one.

Hey I've been trying to use EPU on my computer to run lower clocks when I don't need my OC. However, after I've configured my OC in the bios and I go into the OS, it says that EPU is disabled and I have to turn off the overclocking in the bios in order to use EPU. How did you get around this?

Do you have AI Suite running? The two apps conflict.
 
NewEgg are offering the P5Q Pro for $120 with free shipping! Use $20 promo code EMCAJAHAD at checkout.
 
same thing happens to me camaro...i think its just the way the board is designed..but im also just learning the new features so if somebody has a way around let us know.

I disabled, speedstep, c1e, and LLC (loadline calibration) now that the cpu runs full speed i dont have any problems with full screen video stutter or freezing, and my mouse stutter was just spyware..that i quickly got rid of.

Forgot to mention im also on the original bios, for p5q-e ..and things still work fine. If i do have any crazy problems ill update the bios.

I don't think I do since I've never used it, but I might have installed it. I'll check when I get home, but can you explain the overall setup to have in order for this to work properly?

I'm also having a similar problem. I think you have to have the "AI Overclock" set to "Auto" instead of "Manual" for EPU to run normally.
 
Asking again here since I couldn't get a reply over at xtremesystems.

Can the fan connected to SYS_FAN be controlled through Fan Xpert?
 
According to my manual for my P5Q-E, only the CPU-FAN and CHA-FAN 1-3 can be controlled by the Q-Fan feature.

Sorry, when I read your post the first time I didn't notice the BIOS OC, I was thinking we were talking about the Six Engine application. If you OC in BIOS, Six Engine won't work, that is true.

You basically have three OC options (that I know of) -
1) OC in BIOS (most options, highest OC possible, but locked - can't change on the fly)
2) OC in AI Suite (common OC options - FSB, Mux, memory voltage and freq, and PCI-e freq) and
3) in Six Engine (only FSB adjustments supported in turbo mode but you can also underclock in max power savings mode. Performance changes with the click of a mouse)

IF OC in BIOS or AI Suite, then no Six Engine.

I set up my rig originally to OC in BIOS and I messed around with that for a week or so. I was able to OC to 3.7GHz with fairly reasonable Vcore. But I've really gotten to like the Six Engine app. In turbo I moved the slider over to a 20% OC. That made for a 400MHz FSB and 3.2 GHz at stock vCore and stable. I keep SpeedStep enabled so at idle it drops to a 6x 400MHz - 2.4GHz.

Then in the max savings mode, I underclocked it way down - slider bar again. 291MHz FSB, locked to 6x, 1.74GHz - 0.94 Vcore. Perfect for web surfing.

On my P5Q Pro, it can control a 4 pin CPU fan and three 3 pin fans. Is that your question?

Eh I would love to use EPU 6 but I'm not willing to sacrafice my 3.1GHz for it. Thats lame. :(

Well you could have two BIOS profiles I suppose, one being stock. But you probably don't want to go through the reboot. Did you ever try to OC the FSB in EPU 6 turbo mode? If so, how far did you get?
 
I did, but it wasn't very effective for my setup because the EPU turbo mode is limited, and my cpu being 1.8GHz stock, it doesn't even come close to my current 3.1GHz because it needs voltage adjustments.

What about AI Nap? It's no EPU Engine, but how do the power savings compare?
 
i noticed that turbo mode is preset to like 3% increase...seemed rather pointless. I didnt know u could change turbo to whatever overclock you wanted....thanks for the heads up!
I'll have to reset AI overclock tuner back to auto so all my Memory timings will be reset back too.

I suggest you walk it up 1% at a time to make sure your rig remains stable. If you go too far you will crash. You may want to download and run wPrime. It is a quick and dirty benchmark/stress test (few minutes) Keep raising the the OC bar in 1% increments and stress testing until it fails. Then back off from that point 2% or 3% for your permanent turbo mode setting.

You may then want to run Prime95 over a long period to ensure that your new turbo settings are stable. An interesting side note is that you have just learned what the highest OC, at stock Vcore, your system can sustain. Have CPU-Z running so you can see what the FSB was. Then should you ever want to OC in BIOS you have a good starting point.

AI Nap is a power savings mode when you are in an idle state for a specific period. EPU 6 and AI Nap work together. You can change the AI Nap wait time in the EPU 6 configuration settings.

Yes I do you AI Nap frequently when I'm away from the computer, but I was still looking for a way to downclock when I am just browsing the internet. As I am now lol :p.

How about using AI Booster to lower the FSB?

Wait...Can you explain that more? I'm not sure I completely understand. AI Nap is similar to the "Stand By" mode in Windows XP whereas EPU cimply changes your voltages/clocks right?
 
Well I got my setup done today. I still haven't had time to play around with it. Only thoughts so far is that I should have bought a HSF with a 4 pin on it for the cpu fan control. My Zalman HSF just has a 3 pin so I have to use the Fanmate 2 to control it.

Besides that so far so good.

I suppose that would work, I've not tried it. The max power savings mode in EPU 6 works for me and I can enter that state with a single mouse click.

Generically AI Nap is kinda like "Stand By" in Windows. Technically it is very different. Standby s a nickname for suspend to RAM (S3) which is a defined power state in the Advanced Configuration and Power Interface (ACPI) specification.

AI Nap is simply an Asus application which provides power savings when you are in S0, normal operating state. AI Nap turns off your display, spins down your hard drives, and underclocks your CPU. The power saving are not as great as Standby or Hibernate, but returning to S0 operating state is immediate. In EPU 6 application, for each profile (turbo, etc) you can configure when AI Nap is initiated or your can set it to "never".

Ya I found it, the only problem is I could use it to downclock, however the voltage never changed so it didn't really help much because voltage is what eats most of the power.

So does EPU 6 work in S0 also? And EPU 6 also lowers voltages/fan speeds whereas AI Nap does not? Just trying to find out the main power differences here:)

EPU 6 works in S0 state, I can't name an application which doesn't. Would be kinda hard to work if you were asleep. :) The EPU 6 manages your entire system while you are doing actual tasks - CPU, GFX card, chipset, HDD, memory, fan.

so people got EPU to work? installed it and did the calibration and set it to auto and it makes some of my games freeze up. It also didn't display probably with my screen DPI at 120. I pretty much uninstalled all the asus software except for PC Probe.
