Dfi Northbridge Voltages & Mosfet Sinks

The mobile I have has seen 2400mhz on an Asus A7n8x 2. D but would like to see 2600-2700 on a DFI, if I don't burn it.

 

I was wondering what NB voltage is default to start with on the DFI? Also what should I look for in raising the voltages on the NB? I understand the ram and cpu but haven't used NB voltages yet, and I'm not sure what kind of crap out to look for? :unsure:

I also was wondering if anyone has found a proven bios version or ubber bios that help in stablity?

One more question, I have covered all my chips on the board with sinks but only temp for now. I wanted to make sure they would fit in all the right places after it was together before using Arctic Alumina Thermal Adesive. But I found that the Mosfet around the AGP are to close to the card so I used the smaller chip sinks, and they don't cover all of the mosfet. I was wondering if it would be a better idea to just cut the mosfet size chip sinks and mount them, or if some one has found a better way to do those if it matters?

 

Links or anything at this point would be great! :P

i'm here to revive your poor, unanswered thread!!! :)

 

 

nto quite sure of default voltages...just set bios settings to default, and it should show up. also, maybe the lowest setting. does the NB have active cooling? if not, i wouldn't recommend on upping the vchip until then.

 

for the mosfet sinks....as long as it gets good coverage, and has good conduction...you'll be fine. but remember, the bigger the better.

I beleive NB is 1.5, but I have never needed to take it off of auto...as mentioned,,,

 

many people have found that raising it actually hurts performance

 

as for the BIOS....

too many variables..... the new 6/19 works very well for me, but seems different bios versions work better for different people...

 

get a Bios Saviour and start testing

 

and on the mosfet, I left my slightly off center... I think it is actually just barely touching my AGP card...

 

 

and here is a pic of a mosfet...ed mobo...

 

not mine, but a nice example with a touch of overkill!

Yes the Northbridge has active cooling. I'm using a MCX159-A cooler and Ceramique so I figured I should be fine with some extra voltage. I'm just not sure yet what is the best norm for raising voltages on the Northbridge. If auto works better I will give it a try.

 

The chip sinks around the agp are a pain because I'm running a Gainward 5950 and the heatsink on that things is big. I had to use some really small heat sinks on the mosfets around the agp until I can find a better fit. I was just wondering how much coverage you really need to worry about on the mosfets and any sugestions on moding for ovclocking. I live in the sticks so little bits help... :lol:

 

 

exeter_acres : where can you get a bios saviour? And the I just flashed it to the bios off of DFI's web site. I think their driver and bios support sucks!!!!!!! I couldn't find bios or driver revisions page and they didn't have enough thinks marked with release dates on their so called updates.. <_< Not happy with DFI support check me down one...! Nice board so far though!

 

New toys are fun until your wife asks why you need a new one!
