DFI Nforce 4 and VX Performance.

[ryanpgroovy]

Just to note , that while DFI is making some adjustments to their NF4 motherboard and bios we have found that swaping slots with 2 good units
may increase your performance greatly when using slots 2 and 4 when using any winbond based product.

If you are already over 250 Mhz this may not work as well , or slot swaping could decrease your performance.


Due to the non-standard trace routing and termination resistance on the DIMM slots as well as drive strength settings in the bios , you may need to swap dram slots to provide error free results with winbond die based products.

If your having trouble with any winbond die product, just swap slots and see how it runs , slot swaping under certain circumstances will provide up to a 50Mhz diference in overclocking


In addition something to note ,when switching from one set of memory to another we have found you may need to hard reset the cmos to allow booting.

what does this mean??

move ram from orange to yellow slots?

or take stick #1 from slot 2 and move to slot 4 and take stick #2 from slot 4 and move to slot 2?

thanks

swap 2 to 4 and 4 to 2...same slots, just switch the dimms about.

[sandybeach]

yeah Ive been telling guys to do this for a few weeks at the shop

Hm, I use the orange slots, is it 2 + 4 ? Working fine as shown here:

Have three different kits of RAM - no reset required after switching from one to another.

Its not always an issue , just with winbond based memory products and even then its not often

If your not having trouble , then dont bother

This has worked for me in my personal system. This DFI NF4 is the pickiest board I have ever seen. That ain't no lie!

[AlterBridge86]

THanks for the info guys - i agree andy, as much as i hate the pickiness of the DFI board though, when its properly tuned the thing is a beast and an amazing piece...i love it

[ryanpgroovy]

it is a great board when tuned properly :-)

also for us XS guys.

take some 800-1500 grip paper and lap the chips down to remove some of the ceramic film/top covering on the chips..

these chips are "So" sensitive to just the slightest heat change that Its helps you still need good air flow, but this and fans without spreaders is the way to go IMO..

and yes this viods your warrenty, lol

Not really a good idea that!! But I can suggest we get the laser out again and see if it helps.

[mrlobber]

Up to 50 Mhz difference just by switching dimms around? Talk about not owning the board but being BY the board

I assume, this applies also to VX memory?

[jiff]

Not just NF4, NF3 the same, also needed to do it with my BH5 chips wierd
