The Unofficial ASUS P5N-E SLI 650i Board Thread

[DeadMan3000]

Does anyone know what speed the firewire port is on the P5N-E SLI? It does not say in the manual whether it's 400 or 800.

 

[nefariouscaine]

still trying to find out if anyone here has experience using ECC memory on this board - i know there are a number of boards out there that on paper don't support ECC and do actually run it - i want to find out if this is one of those boards or not

Per Asus website:

Supports 2 IEEE 1394a connector onboard (1 in back + 1 on board)

1394a=Firewire 400
1394b=Firewire 800

Core2, do you have a copy of the beta clockgen that will work with this board? It doesn't appear to be on the cpuid site anymore.

*EDIT*
Nevermind, I found it. It's out of beta now. The new version has support for 650i.

Hello Everyone,
Just had a few questions. First I just got my new computer. I am very excited. Here are my specs. I got these using Everest Ultimate Edition


e6300 1.86 @ 3025.1 MHz, FSB: 1729MHz
ThermalTake Big Typhoon, 4 x Case Fans, 1 Fan on NorthBridge
CPU Idle: 28C
CPU 100% Load: 58C
NorthBridge Idle: 39C, 100% Load: 42.8C
NorthBridge Core Voltage: 1.56v
Core Voltage: 1.325v
Multiplier: 7
CPU FSB: 432 MHz
Memory Bus: 398 MHz
DRAM FSB Ratio: 12:13
Memory Timings: 5-5-5-12 2T
RAM: 2 x Corsair CM2X1024-6400 1 GB DDR2-800 DDR2 SDRAM
RAM in Yellow Slots
BIOS: ASUS P5N-E SLI ACPI BIOS Revision 0307
Video Adapter: EVGA e-GeForce 7600 GT 256mb

OK, here are my questions. I was wondering if my Northbridge Temp. was ok? Also I was wondering if I was getting accurate readings? I have a temp sensor the came with my case. I placed the sensor right on top of the heatsink on the northbridge. I placed it on the "ASUS" letters. It says 39C at idle. Just wondering if that's a good place to place the sensor? Before I put a fan on the NorthBridge it was at 54C at 100% load. I guess the fan thing works! I've been running 2 instances of Prime95 for over an hour, no lockups, no freezing. Everything seems to be running great. If you all can let me know if my temps are good, thank you.

I set the following in the BIOS:

1400/800
Vcore 1.3875
NB 1.39

Running at 2.5ghz

Temperatures in Core Temp:
Core 0 = 45 C
Core 1 = 44 C

SpeedFan Says:
Temp1 = 35 C
Temp2 = 33 C
Core 0 = 45 C
Core 1 = 44 C

Does this seem alright or is it to high of temps?

Specs in Siganature

Set the Vcore at 1.32 NB auto. Temps are good for that much voltage, I don't think you need that much Vcore or NB voltage at that FSB speed. It will bring temps down. 1.28 Vcore will probably work too.

Alright current settings are:

Vcore - 1.32
nb - 1.39
vDIMM - 2.10

Running at 2.4ghz

Temps under Orthos Small FFTs are

Core 0 - 53 C
Core 1 - 52 C


How does that look for temps?

Thanks

Hi all.

Here's my setup:

E4300
P5N-E
ST DDR667 Memory 2x 1GB
7900GT
Thermaltake 470W
2X Optical Drives
1 Sata Western Digital HD
1 ATA Western Digital HD

[edit]

Here?s the deal. I go to overclock this thing. Just for kicks, I did the AI overclocking at 20% and all worked out just fine. I decided to go for the gold and set the overclocking to manual. I set the FSB to 333MHz and at first had the memory unlinked and set to 667Mhz. I set my V core to 1.43. All other settings were set to auto. I ran Orthos for 10 minutes and Asus Probe showed a temperate of 51C. I then got a BSOD.

I tried to bump the FSB down to 311, giving me a clock of 2.8Ghz. I figured it should run stable here without having to up the voltage any further (Something I don?t want to do). For some reason, the computer will not post. It doesn?t matter what I set the FSB to, it just won?t post. All the AI overclocking settings work just fine and post, and 333Mhz FSB works fine and posts but isn?t stable for longer than ten minutes. Anything in between won?t go.

I went back and looked at my settings and tried to run my memory linked in since mode. Still no go. I left all the settings at auto and I really don?t know what I would have to change as far as voltages to get a stable 2.8Ghz.

I have no idea why the computer will boot just fine at 333 and run for ten minutes, but will not boot at a lower FSB with all the same settings as before. Is there something in the BIOS I?m missing, or that is causing a problem for me? I am using the newest version, 401 of the bios and everything else is running at stock speeds. I?m also on stock cooling but I didn?t see my temps go above 51C with a load from Orthos when I had it set at 333Mhz.

Any guidance you can offer me would be greatly helpful and appreciated. Thanks in advance.

Hi,

I'm having a boot problem. 95% of the time it doesn't get to POST, the video card will throttle up full speed and it'll just sit there with the lights flashing. I've seen people mention this issue, but I haven't seen them find a fix for it, or even the problem.

Sometimes it will end up posting and booting after sitting there like that for a little while.

Sometimes it takes 5 seconds to boot to POST, sometimes 10, usually never, on a very rare occasion it will do it immediatly. It makes no difference if it's a cold boot after being off for hours, or a reboot after being on for hours.

When it does boot, it is rock solide. There's never been any kind of error, blue screen, etc.

I've managed to install XP, update the bios (through windows no less), run multiple instances of memtest error free for at least three passes, and cooked it with multiple instances of prime 95 for an hour, no errors or stability issues. BTW I have the ram installed in the yellow slots. I had tried them in the black slots and it made no difference, so I left them in the yellow slots, seeing as it ran very stable like that.

I therefore deem the ram, though unapproved, to be compatible and good, and the power supply sufficient.

It also makes no difference in boot behavior if I unplug all the periphrials to lighten the load during boot. I know the power supply isn't the biggest, but it is sufficient and I won't be spending the additional money to upgrade it "just to see" and because it "can't hurt", I'm sure it's not the problem.

When it hangs during boot if I let it sit long enough, it will end up giving me a beep code, one long and three short, which indicates bad video ram or no video card. The card has been reseated half a dozen times. That never made any difference. All wires are connected properly and cleanly run.

Sometimes while it hangs I can get it to boot by moving this or that around, tapping the video card or tugging on it a little, moving or just touching a wire ever so slightly.. you do weird things after trying to boot it 100X over the course of a few hours.

Anyway while that seems to work at times nothing has been consistant in that area so I must discount those "results", partially.

Bios is optimized such that everything I don't need is turned off. I set the RAM timming manually to 5 5 5 12 according to specs, and upped the voltage on it to 2.01 something as it seemed that has solved stability problems for alot of people, and seems recommended for this ram. I tested the ram both before and after I did this.. never any problem, but left it at 2.01 volts. Still, it ran stable with everything set to auto.

I have raised the voltage on the NorthBridge to the second one up from the lowest setting, even though I'm not at all attempting overclocking. That appeared to speed up boot/rebooting initially, but it still hangs or boots when it wants to, and usually it doesn't want to. Set that back to auto.

I often get the onboard Lan disabled/frozen after rebooting. I found cycling the router its' connected to will wake it up and allow it to connect every time without fail. I would assume that's a bug in the bios, and so not worth an RMA in itself. With bootrom disabled it seems to help somewhat, but not every time.

I recently benchmarked the video card with 3dmark06. With a few settings like AA and such cranked up it got 2600 or so initially, and with default settings in the program only something like 3200. Is that low, for XP 32 bit, and not overclocked, I don't know what I should get, there wasn't much to compare to.

Anyway something is going to get RMA'd but I'm not sure if it should be the board, or the video card. I dont' have the means to swap out for a known good card to test with, and it is my only PC so I dont' want to wait a month or pay for shipping/restocking fee's especially if it's the wrong component.

One thing to note, the SLI selector card wasn't in the default position asus claimed it should be in. The box for the board had been opened by the store I ordered it from, and I suspected they played with it. Supposedly they use gloves to handle it, and only to check for a warranty sticker on the back of it. Supposedly they would not have touched the SLI selector card, and I've read a few others got their boards with the card set to SLI mode by default anyway.

I'm leaning towards some problem with the seating of that selector card right now. Next move will be to take it right out, clean the contacts with alcohol, and reseat it. It seems to be a fairly flimsy type of connection, but I have also poked and wiggled it around ... results of that were no more consistent than for any other wire or area of the board. I have been unable to find people having similar symptoms due to the SLI selector card.

So I guess my big question here is:

I noticed in CPU-Z that the link width is reported as being 1X, max available 16X. I also noticed from CPU-z reports posted by someone else that their link width is reported as 16X, so I'm thinking this could be indicative of the issue. That's in 2D though while looking at the desktop, so I don't know if that's normal or not. Can anyone give me some input on that? Should it not be 16X, and what could possibly have it set to 1X?

Would that be indicative of an issue with the motherboard, or the video card?

Is there any definitive test I can do to narrow it down to one or the other that does not include swapping it out for a known good card, which I don't have access to?

Usually, when it does eventually snap out of a hanging + beep code fit, the card's control panel will pop up after it boots with a warning saying the video settings are "very low" and I can fix it by clicking on the control panel. When I check the settings, they haven't changed from what I had them set to previously. The card's bios is stock, and it hasnt' been messed with.

Also, after the beep code it will load XP, with no video.

I'd really appreciate any help on the matter.

Also sorry if I didn't include all the right specs.. Here's a few portions of the CPU-Z report:

To my opinion your memory is the problem. linked or unlinked, in fact the memory frequency follows the FSB frequency till (if unlinked) the divider founds a better solution to keep it near needed one. there is a big chance that at 332 MHz FSB in fact the memory is higher frequency that at 333 when divider switched to 1:1 gives you exactly 333 (so 667 as your memory is stated). 311 could be the oveclock limit with your settings.

Check if I am right with (CPU-Z or else), and if so relax timings.

Welcome Aboard cyatic
Your NB temps are accurate and are fine at 39c - 41c. Without a fan on the NB it will heat up quickly. I have my senor in center of the heatsink between the fins on the bottom. Where you have yours should be fine. You might want to get a reading at the base to see if there is and big difference.

Why did you drop down from 2.5 to 2.4?? Try Auto for the voltage on the NB. Keep decreasing your Vcore to see what you actually need and record that info. There is no need to add extra volts. Volts make heat. At 2.4 you could drop down to 1.28

Thanks for the reply. Isn't the point of a divider to allow you to overclock the processor without touching the memory? When I run the FSB at 333 and the memory is at 667 I'm at a 1:1 ratio. So if I leave it unlocked and leave the memory at 667 and adjust the FSB higher or lower, my ratio is not 1:1, but I shouldn't be limited by my ram. If I run my FSB at 333 then my ram is at stock speeds.

I tried linking the FSB with the ram, and lowering the FSB and underclocking my ram using since mode. I don't get how my ram could be causing me problems when I'm underclocking it?

Welcome hardtimes101
Where did you buy this board from? Sounds like someone already had troubles with this board and sent it back and the retailer shipped it out again. Sorry to say it but, there are to many problems that point to a bad board. Is the video card in the blue slot and the SLI selector card in Single mode ??

Thermaltake 470W
2X Optical Drives
1 Sata Western Digital HD
1 ATA Western Digital HD

[edit]

Here?s the deal. I go to overclock this thing. Just for kicks, I did the AI overclocking at 20% and all worked out just fine. I decided to go for the gold and set the overclocking to manual. I set the FSB to 333MHz and at first had the memory unlinked and set to 667Mhz. I set my V core to 1.43. All other settings were set to auto. I ran Orthos for 10 minutes and Asus Probe showed a temperate of 51C. I then got a BSOD.

I tried to bump the FSB down to 311, giving me a clock of 2.8Ghz. I figured it should run stable here without having to up the voltage any further (Something I don?t want to do). For some reason, the computer will not post. It doesn?t matter what I set the FSB to, it just won?t post. All the AI overclocking settings work just fine and post, and 333Mhz FSB works fine and posts but isn?t stable for longer than ten minutes. Anything in between won?t go.

I went back and looked at my settings and tried to run my memory linked in since mode. Still no go. I left all the settings at auto and I really don?t know what I would have to change as far as voltages to get a stable 2.8Ghz.

I have no idea why the computer will boot just fine at 333 and run for ten minutes, but will not boot at a lower FSB with all the same settings as before. Is there something in the BIOS I?m missing, or that is causing a problem for me? I am using the newest version, 401 of the bios and everything else is running at stock speeds. I?m also on stock cooling but I didn?t see my temps go above 51C with a load from Orthos when I had it set at 333Mhz.

Any guidance you can offer me would be greatly helpful and appreciated. Thanks in advance.

Run CPU-z and save the HTML Dump on the About Tab and post the info here. Read Page 92 I have posted a Basic Overclocking Guide there and Bios settings and a lot more info.

I've been using CPU-Z to monitor my speeds so when I get home (at school now) I'll boot up the computer at 333Mhz FSB and save the dump and then post it. I'll read over your overclocking guide as well. Thanks for the reply.

Post what cooling you have. The NB and SB get hot when you overclock

Stock cooling on the CPU, regular heat sink on the NB, and the SB is bare. I have a heat sink / fan combo that I can add to the SB, and if I can add a 40cm fan to NB I will.

I understand that heat could be a problem on the motherboard. The NB never got above 40C with PC Probe when I ran it at a 333Mhz FSB. So I'm just baffled as to why a lower clock won't allow me to boot.

Try setting the FSB/Mem option to linked and Sync.

There are no NB temps sensors What you are reading are maybe MB temps totally different and are only available by putting your own senors on it. All that info is on page 92

I tried the linked and synced option. When I lowered the FSB my ram was actually underclocked but still wouldn't boot.

I get what your saying about the MB temps. The temperature I'm referring to was the motherboard temp, which is probably the ambient temp around the board? I'll have to check it out when I get back home. Thanks for the help.

What FSB setting are you using 1200/667 1300/667?? Try using jumps of 50 1250, 1300,1350 and so on. If you hit a tough spot jump over it. Try 1500/800 or 1500/667 Vcore 1.45 - 150 NB auto. What voltage are you using on your ram and what are your timings? See if your ram will run at 800MHz at the Default FSB of 800MHz 800/800 or 1:1

When I had it unlinked I tried 1000/667, 1100/667, 1200/667, 1245/667 and 1333/667.

Then I linked it, and put it in sinc mode and tried it at all those FSB speeds again and the ram was underclocked except for at 1333 when it was at a 1:1 at 667.

I had Vcore at 1.45 and 1333 FSB ran fine for ten minutes and then BSOD. All over voltages were set to auto and timings were set to auto. I didn't think I had to change any of that since my goal wasn't to overclock the ram right now. The ram runs stock at a 1333FSB, so I didn't think any modifications in timings and voltage were nessicary.

[edit] Additional Information:

I set the FSB:Memory ratio to linked, with a 1:1. The FSB was at 800Mhz default, and the bios automatically put the Memory at 800. The computer posts. All voltages set to auto.
----------CPUZ shows 1.8Ghz clock, 200Mhz bus, and 800Mhz FSB. Under the memory tab, the frequency shows up as 400Mhz at 1:2, 5-6-6-2?

I ran it again, except this time, I unlinked the FSB and Ram. FSB was set to 800Mhz, and the ram was set to 800Mhz, all other settings and voltages were set to stock.
----------CPUZ showed exactly the same thing. Mem frequency at 400Mhz, at a 1:2 ratio with the FSB.

Does anyone know where the sensor for the motherboard temperature is located? By this I mean is it at the top of the mobo near the memory or cpu area or near the video cards or near the bottom.

 

[xen0dude]

my fsb seem to max out around 410. Perfectly stable at 400fsb but I want more....plus I want to find out what is the max OC for my E6400 L633A985 from Newegg (anyone has this stepping?)


I tried upping the nb voltage to 1.7 with a desk fan blowing at it and then lowering the cpu multiplier to 7x (E6400) . The ram is unlinked at ddr800. Did all the things pointed out on page 92 including "Set the VCore Offset Voltage to {Auto] Set to +100mV".

I also tried jumping from 1600mhz to 1650, 1700, 1710, 1717, 1725, and 1750mhz FSB in BIOS but not stable under 1.5v or 1.7v NB with CPU multiplier at 7x

Any more suggestions? Or that is just the limit of my board? x[

At a glance I would say your temp sensor is the little miniature silver bullet lookin thing with a wire strap around it placed to the right of the southbridge IC.
