ASUS P5N-E SLI 650i Thread

Got some heatsinks on the way for the MOSFETS and 7600gt ram. All copper too

I´m not new in overclock, but this babe (P5N-E Sli) is getting my nervous.
My config is, beside that motherboard:
- Corsair 6400 44412 2t XMS2 DHX at 2,08v
- E6850 with Thermaltake BigTyphoon
- just resealed the NB HS with Akasa, as instructed on manual.
- Windows Vista x86

With no overclock and not heavy load (room temperature is a litle hot, around 32ºc) the MB temp gets 56º C and the CPU temp gets 52ºc, I read earlier here that this temperature is hot for NB, I don´t agree, my other motherboard with nforce 4 AMD x16 on MSI diamond plus runs around 66º and they say it´s ok, and my 8800GTX just runs at 77º C. Well, just a observation.

And now some questions:

. CPU-Z points 1,4 vcore when the bios vcore is set to auto, unlinked, frequency 1333 mhz, multiplier to 9 (isn´t this too high for auto on stock?).
. The first hole and only one i found was the first at 1600 FSB, didn´t tried more, because clearing CMOS is just too pain, i have to unplug everything, take the battery, switch the jumpers, get the jumper back on, and, finally, put the battery again (isn´t any way easier than that ?).
. what´s the best to overclock: multiplier low and hight frequency our multiplier stock (9) and raise frequency ?
. how high can i go with the E6850 on air (4 Ghz?).

Thanks in advance

Hey there. You should put those system specs in your sig, it'll help us help you Go to 'user cp' and hit 'edit system' over on the left.

Also, you'll be better off asking these questions over in the stickied P5N-E thread, at the top of the page. There's more people who check in there regularly who have experience with the board.

But to answer your questions:

Yes, 1.4V is too much, but it doesn't at all surprise me that that's what the board is giving you. This board seems to overdo everything on auto

Those MB temps seem quite high. How many GFX cards do you have in your rig? How's the case airflow? Make sure all cables are tied back and kept out of the way so air can flow through your case. As you say, the temps probably aren't enough to damage anything, but from seeing lots of people with this board discuss what their MB temp readings are, most people with a setup like yours wouldn't be seeing much more than 40C at stock idle, and some even less.

When I fail a post, here's what I do:
1) hit the reset button once. 99% of the time if my board never posted once, the ASUS CrashFree BIOS will detect that it failed an OC and boot with stock settings, allowing me to get to the BIOS and change the settings
2) if the above doesn't work (which is almost always the case if the board DID post, but it hangs BEFORE starting to boot windows), I mash the reset button 15-20 times, and then cut power to PSU right away. 99% of the time this will reset the CMOS (have to reset system clock, etc etc). On my current board, out of about a hundred failed POSTs, I've had to do the battery+jumper thing exactly once.

As for your OC, i'd go with your stock multi. On high multi, low FSB chips it can be worth running a lower than stock multi because you get extra performance out of your RAM that way, but you've got a (very) high FSB chip, so stick with your stock multi.

And yeah, 4GHz shouldn't be impossible. Even the lowest FSB walls I've seen on this board will allow for a 444FSB, which will put you at 4GHz. However, based on the temps you're seeing already, you'll probably have to upgrade your cooling situation. And if you're aim is to hit 4GHz I'd really recommend some mosfet cooling as well, as you'll probably be pushing some pretty heavy voltages around.

Hope that helps! Hope to see you over in the other P5N-E thread!

how do i get to the vDimm option in my BIOS its pretty hard for me considering im such a newbie to these things, i've been trying to get my 4x1GB ram to work for days i even got it to POST once but then it just freezed as soon as it hit the BIOS screen so i removed it again, i had to make the NB to 1.56v to even get it to post and it wouldnt go past that and i'm running BIOS rev 0608 now so any help?

Try upping your Vcore some...I think someone said that more ram pieces can suck volts from the cpu.

If that doesn't work try the new sticks without your old sticks, maybe you have a faulty stick.

can't wait to hear how the mosfet cooling works out for you

of course you won't see a temp diff with your currently absurdly low vcore but hopefully you can push the q6600 a little farther with more vcore?

how do you get to the vdimm option? well since it seems you're changing the NB voltage, it's...just right next to the vNB, on the same screen.

it says update does not apply to my system

Besides, I'm sure if you turned up the settings, you'd still get 60fps. Or are you already at max? If you are, don't complain. lol

Sorry dude, but in my opinion, I wouldn't buy a new CPU for your rig. You will see increased max fps, but your minimum won't be affected I reckon. For me minimum fps are what counts. It doesn't help your PC can get 200fps at some point in a game, but you get 20fps minimum at other points. That is a graphics bottleneck (it can't take the load).

Just my opinion. Use it, don't use it.

thanks for the advices bro !!!

but should i go quad ?

E6850 vs Q6600 ?? i just worry of Crysis...

If you want to be "more" futureproof and want better frames in crysis I would go with a quad.

Make sure you downloaded the right one. Theres a 32-bit and 64-bit one.

[Asce]

If you get a Quad you will be lucky to hit 3.0Ghz on this board
