DFI boards and what they do

**Tony** · 03-29-2006, 04:30 PM

Guys it seems some of you are a little confused by the various DFI motherboards and what they were designed to do. I will briefly try and explain here what Oskar has done so that you will all see not all boards are made to do the same things.

NF4, ultra D, SLI D. etc.

Boards tuned purely with TCCD, so much so the first sample boards had issues with Hynix and Micron not booting, they were slightly reworked but did remain TCCD monsters. If you want a good board to clock TCCX dimms this is the board to use.

NF4 eXpert

Market was moving away from TCCD, Oskar designs a board to run 2 gig kits well and 4 dimms at 1T, boards also clock 4 dimms 2t real well and are monsters with UTT, BH5 etc etc. if you like 3d benching then the eXpert will break your records.

RDX200

Same design as eXpert although ATI RD480 chipset. Board is also good with 4dimms 1T etc but is lacking bios support, this due to RD580 board development. If you are looking for reasonable Xfire then the RDX200 may suit you.

Venus

DFI decide to treat the overclockers to something a little special, High quality caps, reworked VRM's and reworked memory traces and drive give us the best of all worlds on the NF4, DDR600+ support with TCCD and 4dimm 1t capabilities. Price was high and all boards sold real fast, in all for me this was the best NF4 board ever made, Rgone from DFI believes this also.

CFX3200

Im guessing here as my board is still on its way to me. Built off the Venus platform with even further tweaks, DDR clock skew, LDT drive tweaks etc. Should be the finest 939 we have seen from Oskar, it brings together all he has learn't over the past 2 yrs into a final 939 board. It should be good with TCCD, BH5, Micron as well as 2gig and 4gig setups 1 and 2T.

Remember though the old NF4 was tuned for TCCD so you will not probably see higher clocks as the dimms will only go as fast as the dimms will go, the DFI boards have been maxing memory now for a long time...so remain level headed about what the board will do.

I hope this helps you all understand where DFI have been going over the past 2 yrs.

Good post Tony

Is that the reason why theres so many issues running the 5v jumper or 3.3v jumper trick on the ultra-d?

**~~cronic~~** · 03-29-2006, 04:40 PM

good info tony, thanks

**ozzimark** · 03-29-2006, 04:42 PM

might just be my luck, but i'd like to point out that i've had pretty nice results with micron chips on my ultra-d thus far, anything from 5b C to 5b F... though i don't have an expert or venus to compare it to..

**GSKILL TECH** · 03-29-2006, 04:43 PM

for the TCCD part
venus is better than expert but still not good enough as ultra-d base dfi nf4mobo

for CFX3200
it still have a little problem with ram but Oskar is trying to improve it.

next board from Oskar is Intel mobo

Excellent recap Tony

The ins and outs of the issue with the 5V jumper are not for me to go into, I know i do NOT use the 5v mode and i mod the older NF4 boards for fine tuning the Vdimm and VTT.

With eXpert etc Oskar actually moved to the power design ATI used on the Grouper board, i was quite pleased with this as i actually advised ATI how i would like the Vdimm on the grouper and to have oskar copy it somewhat was an honour..LOL...i will say vdimm on eXpert, venus, RDX200 etc is real nice, fine tuning for me is just awesome and the amount of power the board can deliver is huge.

Is there something you know that you are not telling us

Will HZ work with rd 580

Ah ok. My expert runs BH5 like a monster but with my ultra-d's even when I'm at 2.8v I get cold boot issues big time with the 5v jumper or 3.3 trick.

Next board = yonah?

HZ is running perfect in DFI RD580.

Conroe is where its at bud, wait a while

Thanks for clearly this up for us, Tony.

From the horse's mouth to your ears.... I'l be waiting with baited breath

**Mussels** · 03-29-2006, 06:20 PM

nice info tony. very helpful. to be honest i've never even heard of venus before.

**racinjimy** · 03-29-2006, 09:00 PM

now lets see if AG lets you post this at dfi-street..........

i say sticky!

Agreed. A lot of people will find this useful.

**Lastviking** · 03-29-2006, 10:14 PM

My cents is thats ultra-d is realy the most pang for the bucks + its still king of bh5 clocks.

Yes Venus is very very good board and its clocks much beter with 4x512 than ultra-d. I dont realy know why someone buy the Expert board..yes if some one need room for 2 gfx the Expert board is good before rd580 are in the stores but if someone not need the room the ultra-d is the best way to go before rd580.

Tony maybe add gfx room to the Expert info + also crossfire + venus on "+ cons".

The CFX3200 is ATI Chipset. How is that Built off the Venus Platform?

**afireinside** · 03-29-2006, 10:42 PM

Venus power circuits and pcb/components I guess...

**Freebo** · 03-29-2006, 10:47 PM

I got an sli-d but almost got a venus for my bday, bought a graphics card insted..

What do you want, a door prize

**MaxxxRacer** · 03-30-2006, 12:48 AM

CFX3200..

I havnt been following mobos lately, but thats the first ive heard of it.. guess DFI is really trying to milk the 939 systems to the end.

**Crankster** · 03-30-2006, 12:51 AM

I've used ultra-D, but that sucker is all issues when running 4 gigs.

**REBEL900** · 03-30-2006, 12:56 AM

Nice post Tony..
