FWIW, after vdimm, VTT, and vcore mods, my Ultra-D is a dream to work with. takes a long time to get it tweaked right where u want it, but when yo finally do, it screams.
I must admit tho, the newer versions for the ultra-d are alot better at VTT tracking, and with a suitable fan on the MOSFET I'm running 3.77volts stable on this board. It's a joy to work with and running BH-5 stable at 281MHz :D
If you all look at the eXpert PCB from around the middle of the board up it is exactly the same as the RDX200, now venus deviated from this and you will see the new RD580 board shares the same design tweaks + a little more, so you could say it was built up off the same PCb as the Venus.
I have a feeling we may see a cheaper NF4 board built off the Venus PCB...something like an eXpert Rev2 or rev B maybe, only time will tell.
My whole point here was to educate the guys who b1tch and moan about the various boards not doing what they want, fact is you have to buy carefully as specific boards do specific things. I am lucky in that i have all the boards here, so it really is my duty to point end users in the right direction and to try and show that boards are designed to do specific things...it is REAL hard to make a board real good at everything, something always has to be compromised.
Some compromise solutions you can still tweak as the end user - if the user is willing to resolder half of the mainboard, hehe :p: :D
The catch is, that you can't change the layout, so, unless it is really good, it have a little sense exchange the components to higher quality ones in order to get higher ;)
From this point of view I favor the Grouper for the caps, since I have older nF2 DFI mobos and they all had issues with the bad caps brands like Teapo, OST and so. Also using Chemi-con KZG caps in the PWM circuits is, IMHO, a bit cheating on the users, when MUCH more quality Rubycons MCZ (not MBZ, MCZ!) or Nichicon HZ caps do there MUCH better job (read - higher OC, since they give higher stability at higher voltages...) ...
DFI certainly know about this issue, that is why the Venus feature all solid polymer caps, like better server mobos do already ;)
might depend on ram and cpu too as to how well it handles 4GB ram... old 4x 1GB Ballistixs @11x274mhz 3-3-3-8 2T at 2.85v on DFI NF4 UT SLI-DR R.AB0 623-3 bios http://i4memory.com/showthread.php?p=19690#post19690Quote:

1T with all 4 dimms full? :confused:
Isn't it solely CPU dependant? And as far as I know all current Socket 939 CPU's can't do 4 dimms at 1T.
Welcome to 6 months ago.
with right board tweaks and board design DFI has been able to pull off 4x dimm 1T at 200-205mhz ish IIRCQuote:

Mem controller is the most important part in the equation of running cmd rate 1T but signal tracing and EM shielding also have some relevance.Quote:

wow i was just doing a search for an old expert thread to refesh my memory about it then this comes up. nice toejob
OMG before read this, I never thhought that my expert can run 4 dimms at 1T
I will try if my bh-5 (4x512MB) can run 2-2-2-5 1T 242MHz 3.14v
Not at 1T. You shouldn't have too much trouble with 1T @ 200mhz though. But 2T @ 242mhz is a little faster anyway.Quote:

nice post.. thanks
So thats why I had such problems with my OCZ VX memory. I thought it was the memory so I RMA it but I loved the tight timings. My SuperPi dropped from 26mins to 33min with my new 2 gig memory. Still, my gaming is better so I am happy :-)Quote:

I dont understand yet, is expert can run 4 dimms 1T only @200MHz?Quote:

It's not the Expert. It's the CPU memory controller. The Expert just gives you a good chance to get 4x512 1T at 200mhz, unlike many other boards. I couldn't get my 4x512mb BH5 stable at any higher than 204mhz with 1T, no matter how much vdimm. Heck, give 240+mhz a try, maybe you'll get luckier than me and others.Quote:

How can I expect my micron -5b D chips to run on my eXpert?
my experts wont boot using bh5 on yellow dimm, help ....
(with ultra-d it doesnt matter)
just use the orange for 2 dimm overclockingQuote:
