So I built a new computer the other day and have been trying to get Vista up and running on it. After I got all my drivers up to date most of the errors cleared up, but it will still just freeze up after being on for a while (need to hold the power button down to force a reboot).

This tended to happen when I was installing applications so I was thinking the CPU might have been overheating (system specs are below). Acording to ASUS Probe, it was at about 44C when it would tend to die. I put on some arctic silver 5 thermal paste and its running cooler now and I thought it might have fixed the issue at first, but now I've seen it freeze up with the CPU around 38C.

So now I'm wondering if the motherboard could be overheating? It was reporting around 47C during the previous freeze. What is an expected temp? And if that temp is fine, any ideas on what else I should look into? I tried updating the BIOS to the latest version, but that didn't fix the issue. I figured I could try installing XP on it this evening to see if thats any different?

System Specs:

* ASUS P5N-E SLI LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard

* Intel Core 2 Duo E6750 Conroe 2.66GHz LGA 775 Processor Model BX80557E6750

* EVGA 512-P2-N773-AR GeForce 8600GTS 512MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card

* COOLMAX CUG-700B ATX 12V( V.2.2) 700W Power Supply

* Creative Sound Blaster X-Fi XtremeGamer 7.1 Channels PCI Interface Sound Card

* Pioneer 18X DVD±R DVD Burner Black E-IDE/ATAPI Model DVR-112D

* Western Digital Caviar SE16 WD5000AAKS 500GB 7200 RPM SATA 3.0Gb/s Hard Drive
(I have two of these setup as a mirrored RAID)

* CORSAIR XMS2 DOMINATOR 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4D
(I've got the speed of these manually set in the BIOS to what is recommended by Corsair and Memtest86 says its all good. The Vista memory test application will ussually freeze up on the second pass though - I assume for the same reason Vista is freezing)


Any help would be appreciated,

Ryan

Ryan, looks like you have the same setup I do. It's your ram. Go in to the settings and select the ratio that makes your ram 666 mhz (or something like that) to guarantee that it's stable. Read the past conversations on the last two pages if you need more help. Best of luck

Looks like that might have stabalized things. Kinda sucks, but I guess that sucks is better than broke... ;) So in the end this is the fault of the motherboard right? In other words, should it have been able to function with the original settings, and would asus take it back because of the fault?

Thanks for the quick reply,
Ryan

You can try that excuse, but I doubt it will work anywhere. The ram is technically working... The difference in speed doesn't seem to be noticeable for me though. I'm thinking about getting some faster ram, but new snowboard gear is higher up on my priorities. I'm guessing you don't have extra money to blow on ram, and judging by your setup, you should be golden in terms of gaming power. Save the money, put it toward a 8900GTX or something after that.

Hey guys, first time poster here, looking for a little help as I'm not too technically savvy these days (last computer I built was when the GeForce 4 was top of the line). I built a new system around this motherboard and have had nothing but problems with it locking up whenever I attempt to do anything more involved than surfing the internet (and sometimes not even that). Here's what I've pieced together:
Intel Core 2 Duo E6850 Processor (stock @ 3.0 GHz / 1333 FSB)
ASUS P5N-E SLI Motherboard
Corsair TWIN2X2048-6400C5DHX (currently placed in the yellow slots)
Western Digital SATA 500GB Hard Drive
EVGA GeForce 8800GTS 320MB Video Card
Creative Sound Blaster Audigy SE Sound Card
Ultra XVS Modular Power Supply (600w)
Antec P182 SE Case

I originally had an Antec power supply which I swapped out today as I heard from a friend about how Antec PSUs seem to have a problem with ASUS motherboards, but that didn't seem to solve the problem. I am running XP Pro (was installed from a pre SP1 disk) and I simply haven't had any luck narrowing down what the problem might be. I read a little about Memory settings, but a lot of those seemed to be with really old BIOS revisions (I flashed mine to 0608 before installing anything). I'd appreciate any help and advice you could offer this newbie! =D

Hello fellow P5N-E SLI mobo users.

I had the bad luck of getting this mobo along with 2x1GB OcZ Gold PC6400 rev 2 ram with factory timings of 4-5-5-15. I had bios version 0505 and when I had the modules in dual channel (yellow or black slots) the PC froze at least twice a day and I had to reboot. I tried each of the modules separately on their own and they worked fine completing 2 hours of memtest with no freezes or errors. I put them in dual channel again and raise the voltage from 1.8 to 2.08Volts with freezes again. I changed the timings from 5-5-5-31 to 4-5-5-15 but still I get the freezes. I even updated the bios to the 0703 version with no success.

In order to make it run stable I had to put the memory modules in single channel in slots 1 and 2 (yellow and black). The machine has been stable since but I have half the bandwidth of a dual channel memory and I can sense that when the PC is working.

I am considering trying dual channel again by raising the mem voltage to 2.2, changing the timings to 5-5-5-15, unlink the FSB:memory and set memory freq to 860MHz. Would that help things in your experience or does it only work when the frequency is decreased to 667MHz for example?

Also would buying ram in the QVC list of the P5N-E help?

Thanks

I tried to take it up to 860MHz by setting the FSB to Memory to Manual but it wouldn't boot so I did the following:

Changed the memory speed to 667MHz, set the timings to 4-4-4-12 1T, set the memory voltage to 2.17Volts and rebooted.

I did memtest, orthos test and everything checked out fine with great stability. Only strange thing is that the Core voltage increased from 1.36 to 1.46 which I believe is pretty high. What do you think?

It seems that this chipset has a problem running 1333MHz CPU's.

Always run your memory at 2T command rate. That's the first step towards stability.

Set all the values, including voltages, manually. That includes VCore and memory Voltage.

If still unstable, set the Northbridge voltage to 1.56V.

And set the overclock to Manual (even if you are not overclocking!), e.g. 1333/800.

Pay attention to the actual RAM speed below the "set" window in BIOS. Make sure it is 800, or 667, not anything like 811.7MHz or so.

Good luck!

Hi and thanks for the reply :)

I managed to stabilize it in dual channel at 667MHz with 4-4-4-12 timings, 1T and 2.08Volts. You think it would be stabilized even if I had 800MHz and 2T instead of 667MHz and 1T?

Also what's a good voltage for Vcore at these settings?

Thanks!

If you are stable with 1T, I guess you can leave it. It is very rare with 1T, and the possible bandwidth gains are minimal on Intel platform.

If you see any signs of instability, change the command rate to 2T first.

My VCore is 1.3V, and I believe that you shouldn't need more than that. The maximum rated for my CPU is 1.35V, so as long as you don't go beyond that you should be fine.

Try 1.3V, and increase to 1.3125V if unstable.

I just realized that my board only goes totally stable in sync mode. even modes such as 1333/800 and 1400/800 are never totally stable in my system. I've recently been running 1500/750 stable for weeks now, although 1500/800 is pretty unstable. I'm also letting the bios decide all memory timings now, except the 2T. This means that my ram is running a bit slower (4-4-5-18 instead of 4-4-4-12), though I think it's worth it, as it seems to make things more stable..

Bat,
I might be having a similar problem, though after reading through yours I'm not quite sure. I have Vista Home Premium installed, and my network connection is listed, but *something* is wrong (bear with me here, I don't know the actual words/phrases to use). The little network icon in the lower-right tells me I'm connected but with limited connectivity, which translates into not having access to the internet.

I just upgraded to this board, and have it with a Core 2 Duo e6750. Everything is stable and being reported properly, this is the only issue I have (I'm at work, which is why I have internet access).

After reading a few posts, I will try uninstalling the drivers, but I have a problem there too, as even when you "uninstall" the drivers, upon the next reboot Vista automatically detects your 'new' hardware and reinstalls the drivers! Any ideas there?

I also saw mention of installing the drivers one-at-a-time. And what about the nForce Network Access Manager? Should that be installed, or does it just complicate things?

It should be noted that this is pretty ridiculous to NOT have work out of the box, and to have to go through this trial-and-error junk. But maybe I'm the exception. At any rate, ALL suggestions are very welcome.

I have the latest BIOS, and yes the network adapter is enable in there. Does the 1394 affect anything?

Hi Swartzybaby,

Good timing on the post because I figured out my problem today. And I do mean today, about 30 mins ago. That's after searching the web for answers for months. The good part is, what I found looks to concern all 650i owners, not just Asus. Since the nic is supporrted by the chipset, there is an onboard nic on every 650i board regardless of manufacturer. Furthermore, you will all be happy to know this little issue gets worse over time; have you seen svchost.exe start using up more and more CPU until it is hogging 90%? It will happen eventually because it appears that changes to network settings (only big changes, like uninstalling/reinstalling drivers) will cause this issue to get worse by adding additional invalid registry entries which XP cannot interpret. Instead of giving up, it keeps applying CPU to the problem, but it will never find a solution on its own, you have to help it out.

The problem is that either Microsoft or NVidia has added entries to the Network settings in the registry which are invalid. The Name type in the Connection folder should only be type REG_SZ. However for 650i boards, instead of being that specific type, it has a hex number as the Type. That is invalid. The good thing is, the solution is simple. You only have to delete the bad values to make the good ones show up. Have a look at my post in the nvidia forum for the complete solution :

http://forums.nvidia.com/index...?showtopic=44038&st=20

Sorry, look for the big posting under my screen name on page 3.

BM.

Thanks for the reply. I looked in my registry, and all of the "Name" values/types were the correct REG_SZ entry. So, I'm still confused. I ended up going to Staples or Office Max (they're so similar, I can't even remember which one it was!) and picking up a $15 NIC card, and all is now well. I would, of course, like to know what's up though.

I remember having this exact same problem before with a different nForce board (years ago), but I assumed they would have gotten this taken care of.

I've tried uninstalling, reinstalling, unplugging, turning on/off in BIOS, different BIOS versions (608, 703), "resetting" the nVidia adapter through Vista's troubleshooting steps, all to no avail.

One thing I did notice in the registry is that not all of the entries had the:

"PnpInstanceID" name at all, but not knowing enough about it decided to NOT delete those entries.

I may play around with it some more sometime.

ransom18:

if your system is totally stable, you have nothing to worry about.

With my board however, I get a crash every once a week or so if I'm not running in sync mode.

You achieve sync mode by selecting it in the bios. it's in the same page where you select ram speeds and fsb speeds.

it will cause your ram speed to be proportional to your CPU speed, which means that you might have to overclock (or underclock) your ram to achieve your desired cpu speed.

Hello everyone at Anandtech!

I've had this topic bookmarked as it's been extremely useful to browse and keep up to date with the board, and the wonderful section on Overclocking by Core2 helped me complete my first overclock.

However, that is where my problem lies. On XP, I reached this overclock which was steady for 10+ Hours on Orthos:

3.2Ghz
400MHz x 8
VCore: 1.40v
NB Core: 1.563v
VCore Offset: Auto

However, upon upgrading to Vista, the overclock was rock steady during gaming, but I would receive various BSOD's 90% of the time when shutting down or putting into sleep mode.

My first action was to remove the overclock and reinstall Vista and all the drivers. It worked, everything was rock steady, no BSOD's when shutting down or putting to sleep. However, when I overclocked back to the above values, the problem started again.

Looking in Windows Event Viewer I've noticed these errors appear everytime I start my Machine (at stock and overclock):

IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 7, function 0. Please contact your system vendor for technical assistance.

There are 3 more of these errors, one for PCI slot 3, 5 and 6..

According to Microsoft Support (link) These errors are not a problem and can be safely ignored. That IS the case for when my system is on stock, but when overclocked, I get the BSOD at shutdown and sleep.

So after doing my research I'm diagnosing that it's something wrong with the ACPI, but is there any way that this can be fixed? Is it not getting enough juice?

Thanks for getting this far! Any help would be extremely welcome

Kyle

I believe there is a setting in the BIOS determining if Windows or the bios sets the IRQs. It's called PNP OS or something like that, and it should be left off even if you're using a PNP OS like windows XP or Vista.

Check that setting. Also check that you have sufficient cooling on the south bridge. I believe the south bridge chip is responsible for the PCI bus.

Thanks for the reply AMelbye.

I forgot to mention that under PCIPnP in the BIOS, "Plug and Play O/S" is set to "No" (although when set to yes the problem still persists) and "Primary Display Adapter" is set to "PCI-E"

I don't have any cooling on the SB, apart from the air bought in by the case. It's an Antec Nine Hundred so the air flow is good, but I doubt it's enough to cool the SB if it is in fact getting a bit toasty.

How would I go about checking the temps of the SB?

Thanks

@ kscd

I don't think there is a way to check S/B temp apart from a handheld temp probe or similar. you could add a small heatsink to it and that should help its temp.
I think you irq problem is the slot you have your x-fi card in, try moving it to the second or third slot, I prefer the third slot for creative cards.
Which bios have you got 0401 or 0608, I haven't heard of 0408 ;)
If moving the card doesn't help maybe reflash with the bios your using and then resetting bios with the jumper.

Plug and Play O/S is set to No, its the best setting so leave it.

Hope this helps
Rob

Edit: Also disable anything that is not need in bios

Hi Robohl, thanks for the reply.

I forgot to mention that I tried removing everything from the PCI slots, drivers and all ( which is jus the X-Fi and my Belkin Wireless card, unfortunately as the board doesn't have on-board graphics I had to leave the graphics card in) and all the errors persisted.

I think the only option is to flash the BIOS I suppose. I've done this once before no trouble, to get to 0401 from the original BIOS. But I have a couple of questions:

1. Is it be best to remove the non-vital components during hte flash (the X-Fi and the Wireless card) and add them back in later, after the flash?

2. Which is the best BIOS to upgrade to? I've heard that the latest, 0703, is pretty lame of overclocking.

I'm really not keen on flashing the BIOS, its a final resort, so if I do I only want to do it once.

You're right, my bad! Was a typo, meant to be 0401 ;)

Thanks!

EDIT: On hind-sight, I could have removed the graphics card as well, booted up windows etc, restarted and putting the card back in, check if the errors are in the Event Viewer when I boot up again.

Hi

If your using 0401 and try to upgrade to 0608, it can only be done by floppy as 0401 seems to think 0608 is a downgrade bios "Asus stuffed up" and yes I've tried 0703 and it's a nightmare for a lot of reasons.
0401 or 0608 are the best but as above you need to floppy.

Now for a simple reflash of 0401, just place a fresh copy of bios file on to a USB stick thats formatted to fat and then use EZflash ie: Leave USB stick in port reboot computer and enter bios (DEL) and go to profiles select EZflash or reboot computer and hit ALT + F2 instead of delete to open EZflash.
In EZflash your USB stick will be scanned and then select bios file and reflash, after flash reboot and enter bios (DEL) and select LOAD BIOS DEFAULTS then SAVE AND EXIT, reboot and shut down power and pull out the power cord and use jumper to clear CMOS, place jumper in normal position, plug in power cord and start up computer and enter bios (DEL) and set up your bios to your spec's.

Leaving the cards in or out shouldn't make a differents, but since you have irq issuse's leave them out during reflash and put one of them back in, with a boot to windoze to let it get configured and then the other card.
Put the X-FI in the bottom pci slot and the wifi card in the top one.

I don't think you can boot to windoze if there is no graphics card. Its seems more like you bios is somewhat courupt.

Hope this explains enough, just let me know if theres anything i missed or dont understand.
