Update - I apparently have a bad board, or the board simply doesn't like my high quality 1GB Corsair RAM. Installed the same RAM, including all 4 sticks, into a Gigabyte P35-DS3R without a single issue or hiccup. The ASUS goes back to NewEgg via RMA. I've used ASUS boards in the past without issue but this board caused me umpteen hours of grief and frustration. I even tried to phone ASUS but gave up after 45+ minute hold for tier2 support.
Hi m8. Havent read all the posts since you started with your problems.
It sounds like you are running your Ram at 1T. Your 2GB are double sided so its highly unlikely they will be stable at 1T. Your 512 is maybe single sided so maybe they can do 1T.
Yes, they are maybe reported by SLI or EPP or whatever do 1T, but have you tried 2T?
Think it says on Page 92. Use black slots. Set timings manually and use 2T. Set Volts.
Your prolly already tried all this, just wanted to make sure.
how much of a performance drop can be expected from running the ram at less than sync speed?
My 800MHz Corsair CL4 ram won't do 850MHz even at 5-5-5-18, so I'm being forced to leave my memory running at less than sync speed to be able to achieve the FSB I want (2100 or 2200FSB would probably be ideal for my E6300. 1600FSB is at least far too little!)

btw, I made a simple calculator in excel for this MB. all you have to input is FSB, desired FSB/RAM ratio, multiplier and stock multiplier, and it will tell you all speeds, including the speed of the NB which might prove useful when stuck at a certain OC.

I am working on a new build. As many have tried 4 sticks of RAM in this board and failed to get it to work, I am now one of them. I started with one stick and added one at a time. It never failed to boot. The only setting I changed were the timings and DIMM voltage. Set to 4-4-4-12 2T @ 2.178v. I could not ever pass Memtest86 #5. I now have 2.5GB (2 x1G +1 x512MB). I have passed #5 6 times and the full default tests 2 times. I consider it to be stable in this configuration. I am not a gamer and will do no overclocking. I realize that with 3 sticks I am not running in dual channel. Since I probably would do just fine with 2GB but since I have the 512MB stick I may as well use it. My question is: Will the system run better with 2GB in dual channel or 2.5GB non dual channel? i.e which gives better performance or does it make any difference?
I believe 2GB dual channel in most cases will outperform 2.5GB single channel, as the bandwidth will be doubled. though I have to evidence to back up my opinion. You may want to consider getting a matched pair of 512 chips for a total of 3GB, although be prepared to spend time tweaking your system to make this work
If you haven't done it yet, raise the Northbridge voltage to 1.56V, but add a fan to help cooling.
If that doesn't work, reduce the RAM frequency to "Unlinked" 667MHz, setting the CPU frequency manually, too. (1333MHz, correct? - am not familiar with E8400 multipliers).
Good luck!
Was speed was all of this done at?
If you read previous posts you'd realize that there is a FSB hole between high 700's and low 800's, so you should just overshoot and clock your ram at 850MHz, see if that does anything, and also update your bios to 0803 if you haven't done so already.
Then post back, because a lot of people have 4GB running on this board, me included.
You just have to know the right settings.
When you raise your ram speeds to 850, you're going to want to loosen your timings to 5-5-5-15, 2T, unless you know your ram can do those latencies at those speeds.
Mine can.
Hi Everyone,
I have a question. I have our motherboard. Everything runs fine. Here are my specs:
BIOS: ASUS P5N-E SLI ACPI BIOS Revision 0608
e6300 1.86 @ 3150.0 MHz, FSB: 1800MHz
ThermalTake Big Typhoon, 4 x Case Fans, 1 Fan on NorthBridge
CPU Idle: 33C
CPU 100% Load: 48C
NorthBridge Idle: 35C, 100% Load: 42.8C
NorthBridge Core Voltage: 1.56v
Core Voltage: 1.440v
Multiplier: 7
CPU FSB: 450 MHz
Memory Bus: 400 MHz
DRAM FSB Ratio: 8:9
Memory Timings: 5-5-5-12 2T
RAM: 2 x Corsair CM2X1024-6400 1 GB DDR2-800 DDR2 SDRAM
RAM in Yellow Slots
Video Adapter: EVGA e-GeForce 7600 GT 256mb 46C
Here's my problem. I can play video games fine, no lock ups, resets, nothing bad. Everything is a o.k. Everything I do with this computer is good no problems. Ran Orthos, Prime95 for a day, no problem. Ran Memtest, same results. Here is my problem. When I play any type of video file, my computer locks up/freezes. Video in video games play fine, it's only when I play a video file in windows that my computer crashes. When my computer is at "normal" speed (no overclocking), I can play video fine no crashes.
I've tried moving the hardware acceleration tab to the left on the video card settings. same thing. Anyone have any advice? I e-mailed EVGA, and they said run the card with the default windows video driver. HUH!? I tried that and it works fine. Is there any other fix fellas? I would like to be able to use my video card the way it was supposed to be used. If anyone can help I would appreciate it. Thank you.

the problem might be with your ram/fsb ratio. try 1:1.
also, make sure to disable any CPU power management settings (speedstep in particular).

Your problem my friend is an unstable system. No really.
I had similar problems before. Everything was fine, but only video would do strange things to my system.
Also if you are using any codec packages, uninstall that and only install codecs that you require, so you don't run into any codec conflicts.
Make sure your video player is also configured to use only certain codecs you have installed.
It could also be a corrupt video driver installation, but I doubt it.
If you're using hardware acceleration in the form of Nvidia's PureVideo decoder, you should make sure you've installed that properly as well.
Otherwise I would say it's your system. It's not stable.
This whole time I was running 3.5GHz on my system 1750 FSB (437.5 * 8) on my E6420 and I thought I was stable, because I could game and leave my system on for hours at a time, but as soon as I left videos on overnight, I would wake to a frozen system.
So yes, you should back it off a bit with the overclock or try to find a stable voltage setting.
I see you're at 1.56, sooooooo it couldn't be a voltage issue. I"d say turn it down a notch my friend.
Cheers,
Mike
You know, I think his CPU should be fine running at 3.15GHz. I have the same CPU running stable at 3.5, and I still have headroom so to speak.
The NB voltage isn't a problem. Should be able to run 1800FSB at 1.3V, and the CPU voltage isn't a problem since that would cause errors in prime 95.
Now here's my current settings:
2000FSB
7x multiplier
666.67MHz RAM
CPU voltage 1.45V
NB voltage 1,5V
This gives a 2/3 memory ratio, and a CPU speed of 3.5GHz
this is completely stable, or at least so it seems. have been running this configuration for about a week now. The only thing is, it doesn't seem that much faster than running 1600FSB/800RAM, as (I believe) most of the performance gain is lost due to the RAM running at less than sync speed.
Anyway, I believe the problem lies in the FSB/memory ratio.
Would you like to share your settings (voltages, timings, frequencies), with the rest of the class...?
I just got myself a 2GB set of crucial PC8500 ram, so that I can run my ram in sync mode with my 2GHz FSB.
The weird thing is that it was unstable at first. I turned all my fans up, and this stabilized the system.
I don't understand why. Does a higher RAM speed put a heavier load on the NB, or was there some other component in the system that needed the additional cooling?

When I booted the first time it said something like "UNKNOWN CPU....PLEASE UPDATE TO THE NEWEST BIOS TO UNLEASH THE FULL POWER OF THE CPU". I updated the Bios to 803 and the message went away. I wanted to run stock so I changed very few settings. Here's what I did:
1) Set AI tuning to Manual
2) Set Memory timings to 4-4-4-12-2T
3) Set Memory Voltage to 2.178
It never failed to boot with those settings but it wasn't stable when tested with Memtest86. I tried various Memory Voltage and NB Voltage settings but just couldn't get it stable. The last thing I did was set the FSB-Memory Clock to Linked and then I was able to get it stable according to Memtest86. I ran test number 5 five times without any errors and two complete tests without any errors.
CPU-Z 1.43 reports the following:
Core Voltage 1.344v
Core Speed 3000.3 MHz
Multiplier x9
Bus Speed 333.4 MHz
Rated FSB 1333.5 Mhz
Dual Channel
DRAM Frequency 400.0 MHz
FSB : DRAM 5:6
what drivers do you guys use? i recently installed the newest drivers from the nVidia webpage, and it's making the mouse and audio glitch twice a second.. Are the ones on the Asus site the best available? They are pretty old..
I've been using the NVidia latest (August 2007) drivers.
But I've had a bad conflict with Logitech mouse drivers, so I uninstalled (and never installed in Vista) the SetPoint.
It would show errors in the Event Viewer about a failing Hard Drive!!!

HELP!!! i updating to the newest beta bios to see if the memory hole is gone like some users say but its not stable for me and i cant downgrade bios gives me an error message when it checks the bios to see if it works or not. What can i do???
"Downgraded ROM file was not suitable for the system." is the exact messag.
