Candyman, did you do this mod?

How much improvement did you get?

If so how do you make sure the pot is not at full bore when you power up.

I wonder, can you use a smd grabber instead of soldering?
And can you use a resistor instead of the pot, like we did the 8rda's..

LOL Y do that just make sure you can undo the mod without it being notice that it was modded. I use SMD grabber's I got from a friend here @ these forum's I believe his user name is OnDborder and that way you dont have to solder on the board

So can you use just a resistor or do you have to use a pot? Like we did on the 8rda's..

Pot work's best. I took a chance and used 2 x 10K vr's for the vcore and 1 x 10K vr for the vddim the vddim I had to turn down the vcore I was @ 1.72 when set to 1.65 in bios.

I just plan on doing the vdimm. So how do you avoid frying your ram with that pot?

I forget what I set bios @ but as of right now I'am running 3.3 and I had to turn it down to get there with the 10Kvr. Just set the bios to lowiest vddim and you should be ok make sure pot is @ 10K also . A64's dont like really high vddim with there onboard mem controller so it is not recommended to go over 3.3 for long period's.

Nope sure didn't. I even tried the bios 5\16 or whatever along with a unplug power and wait 10 min's and still have vcore flux issue I just wish they would come out with some beta bios or something hell it's been over a month sence the last bios release.

jon, have you seen this?

Edit: Link seems to be dead in that thread for the bios, but I have a copy of it. I haven't used it because I haven't experienced the problem (stock voltages), but I'd be happy to host it somewhere if there's interest.

The modded BIOS only has the 1.75v and 1.8v options available for Vcore. It still only has a max of 2.8vdimm...you would need the vdimm mod if you want more than that.

BTW Here is a copy of the modded BIOS if anyone wants it.
