Asus A8N32-SLI initial impression....WOW!

This mobo also only uses 1VTT regulator when the datasheet even shows there should be two. (Luckily I happen to have a few of them on hand, I'll try installing a second one)

Also, I'm really lost as to a Vdimm mod. I havn't been able to find the regulator chip, or if the Vdimm is driven off of the 3.3 or the 5V rail. (If it's 3.3 I'll just do a Vdimm = 3.3 mod)

Someone help me


Vcore is setup really weirdly on this board too. The regulator they chose is only capable of handling 4 phase power, where are the other 4 phases coming from? You can probably guess, that extra .2V option. There's an analog switch and 2 little controllers for those extra fets.

I'm pretty sure it runs off 3.3v else it would support a lot more than 3.2v. Vdimm is rock solid when I measured, so I don't think you need to really worry about it. I only see one missing mosfet soldering pad underneath the dimms, is that the missing VTT circuit?

I think the warm boot issues I've been having is due to vcore. During a normal reboot, the vcore drops down to 1.42v, then back up to 1.61v or whatever I set it to. But above 2.7Ghz, it just stays at 1.42v, no post, no beeps - as if there was no CPU present.

most of the people who have this board are using single core CPUs, so their vcore options aren't as limited.

Argh

How about a vcore mod, craig?
Thanks

The vcore regulator is ing nasty. There's a 1MB PDF on it, and it's something I'm not looking forward to modding. It's more complex than I like.

I'll send the PDF to anyone who contacts me on AIM or MSN. (There's a 200KB file uploading limit here)

Edit: Just for you I started looking into it. It's more plausible than it first looked. Someone tell me the resistance between pin 8 and ground. My chips legs are covered with nail polish right now. It's the ADP3168 very near the CPU.
