I owned an Abit AN9 32X and the max Vdimm is 2.3 to 2.4V.

I Vmd it to 2.7V max and able to OC my AM2 3800 F3 to 3.7GHz, DDR2 >1200Mhz.

Maybe someone should try Vmod on it

Hi, how many mobo revision do we have for M2N-E?

Vdimm mod to 2.45V

I believe this is the limit of my M2N-E

x2 F3 3800@3.43GHz Vcore 1.5V, Micron D9DMH DDR2@1140MHz Vdimm mod to 2.50V.
The DDR2 timings should be able to tighten slightly better

hard mod it by solder a preset on the mobo
can mod to 2.6V if you want

try goggle for the link in 1st or 2nd page in this thread....got link there.
but keep in mind that if do the mod wrongly it may burn your mobo or DDR2 module (maybe both)!

Yes, the same mod.
Just make sure your MUST adjust the preset to higher ohm side before fire up...
If you start your system with the preset at minimum resistant (about 0 ohm) you gonna fry yr ddr2 as the Vdimm >3V

btw, I believe you may adjust the Vdimm without DDR2 module installed. Safety 1st



p/s:

bro,

sorry coz didn't exchange the mobo with you...
I seriously wanna exchange with you but you took too long time to trade and hardly online

btw, no need to sell it off lah...it is a good mobo, just need Vdimm mod

I can do 3.40GHz stable after Vdimm mod to 2.55V, but you still need a good DDR2 in order to do >1000MHz DDR2 speed. Mine stable at 1100MHz DDR2.
for OC>3.2GHz for sure you need a good proc like AM2 X2 3800 F3.

Recommended speed for 7/24 not >3.2G and temp keep below 50C idle or 60C max load.

Refer screenie for my 7/24 rig with CnQ enable

refer to the pic, actually that one is GROUNG point.
Just solder the wire to the round solder point surrounding the screw hole will do.

You may use ohm meter to check the continuity for the "hole" and fan header (black color pin when plug in fan connector).

I am using 20k but I believe 10k will do better (easier to control).

Well, just remove the DDR2 and measure the Vdimm while turning the preset toward the lower resistance range till the Vdimm you want.
I set the BIOS Vdimm to 1.80 first (before remove your DDR lah) so max Vdimm is the measured voltage +0.15V (1.95V setting in BIOS).

if you got electronic knowledge it is simple.
If not sure better leave to someone who know what he is doing...just my advise

aiyo...bro, after solder just a few steps more lah...still need tutorial huh?

refer to pics, make sure you solder the right points.

1. Before solder set your Vdimm in BIOS to 1.80V.
2. Remove all the DDR2 modules for safety purpose (make sure you get the right Vdimm then only you install the DDR2 modules)
3. After solder, measure the Vdimm measure point for actual Vdimm reading.
4. Turn the preset toward the lower resistance range till the Vdimm you want. (glue the preset with double-sided tape to avoid it from moving)

simple as that....
