Also, some games won't install under it, and rarely some 32-bit programs won't run under it, usually firewalls, some antivirus, VOD etc. If all that is OK, then as I said I prefer it to Vista.

Thanks. By the looks of it, Asus provides them, But I'll search around for confirmation. Currently thinking that I might dual boot XP x64 and Vista Ultimate x64 (yeah, I know to install vista first). But I'm also looking at an upgrade at the moment and putting this other machine to server use. Currently looking at the EVGA 680i SLI series, which is heavily OCable. But I still like ASUS. Anyone have any suggestions?

Hey guys I'm ready to start overclocking my system; I looked at the tips on this tread but it doesn't say much about the Q6600s. Is there a good guide out there for a noob at overclocking?

Hi guys this is my first post here.

I read the last 10 pages of this topic but i couldn`t find the problem im having.

ofc i have the p5n-e sli. I was using it bios 0608 with e6420 all at stock, with no problem at all.
Yestarday i bought an e6750, and after reading asus site i upgraded the bios to 0703 and installed the new gpu.

Its rebooting my system all the time. Getting hardware failure after 5 seconds in orthos. Sending me back to desktop after 5 minutes of gaming. Even get a reboot while opening an XLS file!!!

any suggestions?? is it the new gpu that is broken ?, should i go back to 0608 ?? does 0608 bios support 1333 fsb ??

im using everything at stock.
i have 2 gb (2x1gb) OCZ REV2 800 mhz
I dont know nothing about voltages, it is all in automatic.

I did enter the setup for the save and exit thing after installing the new gpu.
Cpu-Z is showing me everything fine. memo and cpu speeds and fsb look fine there.

The temps r also fine 42º CPU, and 40º MB

Thx in advance for any suggestion and sorry for my english :)

No worries for the english.
I'd try resetting the BIOS to see whether that's the prob. pull out the power cord for your computer, then pull out the battery on the motherboard (making sure to ground yourself as to not short the board (see the user guide)). Then cross the jumpers for the CMOS reset, which will be referred to in your manual.
Otherwise:
The OCZ mem might be causing the problems, in that it usually has to be put at a higher voltage than other RAM on the P5N - It's rated up to 2.2V, so I'd take it off auto and bump it up to the 2.1 equivalent (whatever that is). With the CPU (Central Processing Unit (as opposed to a GPU - Graphics Processing unit)) It should be fine at auto voltages as well. Otherwise, probably best bet is to double check with a local reseller.

A few things though.

What is your power supply - and what is it rated
What is your graphics card
what is any other peripherals that you have on the motherboard?
Any other relevant info please include.

If you don't have a power supply that is suitable, it could also give you the errors you are receiving...

Any other worries, please post. Please be careful with changing the voltages on anything, as this could damage your board. Check any reference manuals that are relevant before any manual manipulation of BIOS settings.

Hous,

First, reset the BIOS as described in the manual. Wait 10-15 minutes with the jumper in the "reset" setting, and press the Power button in the meantime to drain the capacitors.

Once you've done that, enter the BIOS and set the following:

CPU Voltage 1.3V (if unstable, try 1.325V, up to 1.35V)
RAM Voltage 2.1V (up to 2.2V)
NB Voltage Auto (if unstable, increase up to 1.56V, but add a fan to NB to cool it better)
CPU "overvoltage" (or whatever it is called) Auto.

Then choose the "Manual Overclocking" (even if you don't overclock), "Unlinked", and set the following:

CPU frequency: 1333MHz
RAM frequency: 800MHz

Set the RAM timings to 4-4-4-15-2T (very important - 2T command rate!).

If you have to update the BIOS, or go back to 0608, use the AWDFLASH procedure as described here:

Good luck!

Thx a lot for your quick replies.

The power supply im using is the one that came with the Vitsuba Master. i think its 550W. Worked perfect with the e6420

Im using a MSI 8600gt oc, HD sata2 320GB WD and a WD 250GB 7200rpm IDE.
dvdr pionner sata2 + floppy.

So u think there is nothing wrong with the cpu ? sorry about my ignorance but instead of resenting the bios why not downgrade it with the ezflash in the bios ?

Al that info about how to reset the bios manually is in the MB manual? or do i have to look arround to find the reset jumper?

Thx again for the info and for the patience :)

You must reset the BIOS after the update, always.

Check for the jumper location and the procedure in the Manual.

After the reset, enter the BIOS, go to the end, "Load setup defaults", "Exit and Save", then re-enter and do the manual settings as described above.

The best method of updating the BIOS is AWDFLASH, but some people are successful with the EZFlash.

Just try the manual settings of the voltages, timings and frequencies...

I just downloaded the manual becouse im at work, the only thing about reseting something with a jumper is a " CLEAR RTC RAM" is that what u guys meant by reseting the bios ?

Couse i thought that reset the bios was about downgrading it to the original bios.

If this CLRTC is correct, in the manual say something about 15 seconds in the reset position. is that correct or should i wait 15 minutes like u told me ?

Thx again!

Correct - CLRTC, page 1-26 of the manual. (Actually, clear CMOS, not BIOS, but CLRTC is it).

It has been suggested by some other AT members that 15 minute (not second) wait is better. It allows enough time to completely "drain" all the capacitors.

Press the Power button a few times, too, during that 15 minute period.

Its working perfect now. I just reset the cmos, set the voltages and freq and it start working great.

Thx a lot for your help guys!

What's the latest stable OC'ing BIOS for this board?

I bought an E2140 for my parents' system since I had a bunch of DDR2 and this board lying around still. With existing 0401 BIOS it had no problems running at my previous 3.0GHz. Read somewhere that I needed to update the BIOS or run into problems with the M0 E2140 and found the 08XX and 07XX BIOS do not OC at all. Like 400MHz max. Really quite annoying.

Looks like Tuvoc and some others are using 0608, while others are sticking to 0401. Just curious as to what people are running, but I'm so glad to be done with this board. Looks like things are getting worst rather than better, and there's certainly a reason these boards are selling for $50-60 now.

Anyone looking to get this board....run, do not walk.....get something else.

A bit radical approach, Chizow, but I have to admit that any change of configuration on this MB might create potential problems.

I have had problems with 0608 - the board would freeze during POST and would require a Reset, to boot (hopefully) on the 2nd or 3rd attempt.

If you can, stick to 0401. As you can see, I have added the 8800GT, and have not had any issues.

Hehe well, I don't think its quite that radical considering this board killed 3 1/2 kits of RAM. After the 3rd kit died (might have killed 1 stick in another, not totally sure) I figured it was time to give up on the board. Asus RMA was pretty useless and I would've needed to get a 2nd board anyways, plus I had the TT Big Typhoon backplate melded to the P5N-E so I was basically stuck with it. Only reason I'm taking a chance with this board this time around is because I have 2x1GB sticks that I no longer use and I'm only going to be running 2GB max.

You know, funny thing, but I have not had ANY issues, besides the mentioned 0608 fiasco.

It had been rock solid since early January until the end of June on 0202, when I decided to "update" the BIOS to 0608.

After struggling with it for about a month, I "downgraded" the BIOS to 0401, and again, the board has been solid.

I do not think that I would like to install the CPU that 0401 does not support though... LOL.

Good luck with the E2140 - please let us know how it works.

It seems like it is an awesome CPU for ~70 bucks, easily overclockable to 3.0GHz and beyond!

I'm on BIOS 0801 running an E6600 at 3GHz quite happily. that's 333Mhz x 9 Multiplier. I haven't even tried to get above that, as it isn't stable (obviously the BIOS rev.) What are the advantages of the BIOSs above 401? Can it run all my system and at what level do you guys think I could get...

hello all,

im just wondering if anyone has pc8500 memory running at the rate 1066mhz speed on this board.

i have some crucial ballistix and as soon as i go over 1000mhz the system is unstable, crashes, freezes you know the drill lol.

i have timings manually 5-5-5-15-2t vdimm 2.25 but it didnt help.

so its running @ 928 @ 4-4-4-10-2t at the moment.

if someone can help me out i would appreciate it.

bios is 0608 but have tried others.

Hi, I'm having trouble booting up with the P5N-E SLI mobo. I just bought all new parts and built it today and I can't seem to find out what's wrong. :brokenheart:

Mobo: P5N-E SLI
CPU: Q6600
GFX: 8800gt
PSU: Silencer 610w
1 IDE HDD
3 120mm case fans + 1 120mm cpu fan/ thermalrite extreme heatsink
2gb (2x1gb) corsair ddr2 twin2x ram

I disconnected all my cd/dvd drives, sata drives, and anything else I could to try and pinpoint the problem. The bios settings are at default as are all the jumpers on the motherboard. When I boot up, it shows the mobo logo screen then it flashes this blue screen for about half a sec then the system reboots. There's text, but it reboots too fast to see anything. Other times, it says "detecting array" then nothing happens and it reboots.

I'm not using the fan connectors on the mobo. I'm connecting the fans to my power supply's 4 pin connectors.

Anyone able to help me? :(

Try to connect the CPU 4-pin fan to the header on the MB - and then enter the BIOS and disable the CPU Fan monitoring (one of the last screens in BIOS).

Only then connect the Thermalrite CPU fan to the PSU.

And review the last few pages of this thread to set all the Voltages/frequencies/timings manually - it is very important to do it (almost) all manually on this board.

Good luck!

And welcome to the forums!
