Hi, I just acquired this board, seems pretty good, the only problem is that it lacks good overclocking options, as I expected...

But it seems that VDDQ and VDIMM are hidden and can be unlocked using the right BIOS modding tools. I messed around a bit with modbin6 but I'm pretty sure I'm gonna mess this up and end up with a paper weight... Anyway, if someone more experienced could give me a hand with this, it would be great.

Thanks in advance. The latest BIOS file for the board (F6) can be found here:

You could have checked its ocing capabilities before purchasing it as there is not too much that can be done besides VDIMM and VDDQ so far and I don't think Gigabyte will ever add ocing options to it.

If you really want VDIMM and VDDQ you can go ahead as you shouldn't have any problems flashing your modified BIOS, don't be afraid.

I got to test this board the other day, it wasn't good and oc'ed pretty badly but we're talking about a board that's not overclocking oriented, it should serve more as a HTPC.

Eae brazuca :D

I was aware of its ocing capabilities before buying it, I'm just trying to improve it a little bit, not making it a low cost DFI or something ;) Just a little Vdimm and VDDQ should be fine to run my venice 280x9 or 290x9 1:1.

If your Venice is able to do it at stock voltages then yes, you'll be fine, if not you're in trouble.

I didn't check VDIMM using my DMM but I guesss the board may be already feeding the slots enough voltage for TCCD but I don't think it will handle Winbond stuff pretty well...

VDDQ won't help much unless you want to break the WR for 6100... :D

BTW, you should check FPCs, some people there tested it and said they were having problems with the board in question

Vdimm is awfully low for my GCCC Samsung... They scale well with voltage, stock 2.55v isn't helping much.

I tried to modify the BIOS with modbin6, but I'm not getting anywhere, I keep getting this "Can't open 2MBIOS.BIN" error when I try to save the modified BIOS =/

Have you tried MODBIN6 2.01.01 ?

You can get it from http://bnobtc.pix-art.com/bnobtc-files/award/

I'm off to bed...

That one worked just fine... Wish me luck! :D

Flashed, and no improvement... I didn't measure with a voltimeter, but I'm pretty sure those hidden BIOS options doesn't do any good =/

I'll have to vmod the board if I want to raise it a little bit...

So you raised memory voltage and you realized that your sticks hit a wall and your memory won't go any higher ?

Sorry, as you can see, you really can't oc'it too much, hard modding it might help but I think is just not worth it, the board is just not meant to be oced.

No, the sticks can go higher, I've tested them in another mobo before this one. The problem is that BIOS editing didn't do any good, probably the hardware for vdimm control isn't even present in the board, those settings might be just a left-over or something. I read that in another forum as well...

The sticks are really cool, it's impossible that they are getting 2.80v like I edited the BIOS to be... They're still 2.55v, which is this board's default.

I'm sorry, you have unhidden the memory voltage option, then you selected 2.80V and the board still reports stock voltages according to VDIMM sensor ? How do you know voltages are still the same ? Have you checked VDIMM using a DMM ?

If it didn't change anything you may be right, the board may not even have the appropriate hardware for memory voltage regulation
