Maybe? Try different settings and see what works. In my experience +150 works best though.

And there are some other tweaks I have read which are lowering the MD and DQS Drive strength down to 0.75x and Lowering the CS and MA Drive Strength to 1.25x and the MEMCLK Drive Strength to 1.00x. Would that help and is that correct?
I do not have much experience with drive strength so I would not really know.

I am surprised that they worked with 1T. Try 2T instead.
The different BIOSes much be choosing different memory profiles for some reason.

Hi DrSwizz. Long time.

I've never dealt with this particular parameter. When overclocking the board, are you saying it's possible squeeze a little bit more out of the RAM but advancing both memory banks by 150? My memory isn't all that good (pun intended) but runs around 850MHz and I'm wondering how much further I can go if I move that particular setting.

Hello there!

Probably, it depends on your memory.
About two years ago I spent quite allot of time trying to figure out the optimal memory configurations using the M2N32 SLI Deluxe and various DDR2 memory modules. Using +150 clock skew on both channels seemed to help on most (all?) memory modules that I tried. With with my best memory sticks (1GB Crucial Ballistix) that gain was quite significant: I was able to lower the voltage 0.2V to about 1.9-1.95V and still have the memory running at 4-4-4-12 at around 500MHz. On other modules the clock skew only helped a little bit.

How did you go about procedure?

What I'm mostly wondering is if I can use the skew to get the memory to run stable at a higher frequency. I'm running the HT bus at 254MHz right now, but would love to push this higher if possible. I'm thinking the system response time will be better this way rather than lowering the timings, which are presently fixed at 5-5-5-18-24 to allow the board to be overclocked. But as I said initially, I'm not well versed at tweaking memory, so hence the noobish questions.

First of all the automatic "reset feature" for incorrect overclocking does not work very well with memory overclocking. You better have your computer with the case open on a desk next to you so that you easily can reset the BIOS.

When overclocking & testing the memory I use a floppy disk with memtest on it & have the BIOS boot the floppy drive first. Then I start by overclocking the memory a little bit past where it is stable, that is I get some memtest errors, but not too many. Then I start altering the settings in the BIOS one at the time and reboot & test the settings o see how many memory errors I get. Sometimes it is hard to tell whether the changes you made in the BIOS settings made any difference so you might want to run memtest 1-2 minutes & then reboot a few times with each setting. When you have reached a plateau for the memory frequency & settings you can start to run memtest for longer periods of time.

Try different clock skew settings to see if +150 works best for you too. You might want to try different DRAM termination voltage & resistance too, those settings helped me when I overclocked a set of Corsair Dominator sticks.
I also suggest that you try both high memory frequences & relaxed timing and lower frequencies & tighter memory timing to see what settings that are possible.
Don't push the memory frequencies too far with the memtest testing without booting into your OS every now and then and and do some ordinary stability testing to make sure that the NB/IMC still is stable.

Has anyone else experienced these Motherboards reporting incorrect temperatures?

I've got 3 of these motherboards all running 9850BE's. All with slightly different setups, all have same case, 2 are utilizing the same cooler while one is using an H50 setup.

3x 120mm Slipstream Case fans 1x80mm fan, Artic Freezer 64 Pro idles 55 degrees c, I've re-seated the the heatsink three times, zero difference

3x 120mm Slipstream Case Fans 1x80mm fan Artic Freezer 64 Pro idles 50 degrees c

2x 120mm Slipstream Case Fans + Corsair 120mm Fan, Corsair H50 watercooling, idles 50 degrees c.

They all climb to 71 degrees c according to logs I've taken, and about 60 percent load.

All these readings come from PC Probe II.

Here's what the readings look in HWMonitor, It shows the cores at 39 degrees c though...............

pcprobe sucks IMO. i would suggest useing your hardware monitor and or core temp. they seem to always be close to what the bios reads.

The only cpu that showed the right temps for me was an x2 5000 windsor,my x3 720 would show correct cpu temp but core temps where 10-15c under.

Arctic freezer's aren't much good for x4 125w cpu's,as for the H50 it could be airflow or the lack of.The core temps are OK in your pic.

What is the case they are in?

As The Fryer said use HW monitor or everest.


Good luck

Just successfully ran Vantage with my 955 overclocked to 4.255. MY H80 is keeping it nice and cool. Couldn't even load Vantage at that clock with my Zalman 9700.

I'm still disappointed with my results:



My buddy is running the same processor but in an AM3 board. I'm sure he is capable of overclocking his NB (which I have not figured out/not sure if the M2N-Sli supports). He is hitting ~14k with his CPU score which I'm sure has to do with his motherboard and plethora of features that are not available to me.
Can you squeeze a little more ref clock and with a lower cpu multi for the same clock?
The faster you can get the NB the better performance you'll see.
If you can get a 250 ref clock that will give you 2000mhz NB(stock AM3 NB speed)(stock NB speed on your MB is 1600mhz.8x200)

Good luck
