im sure you arent allowed to answer this but i had to ask.
Hello
I just got my board this weekend and I started testing with my old bh5 sticks as soon as I placed it in my case. My first impressions are that it's a quality Dfi board which also have some downsides. First of all I couldn't overclock 1mhz with my sticks in the yellow ram slots. When I put them in the orange slots I managed to increase the ht frequency to 270 mhz and nothing above it would boot. I would have to increase the ht frequency from within windows with clockgen. One of my friends bought it too and he told me the same thing about his max. ht frequency which is 270mhz. I think this board definitely needs a good bios update because it has the potential to reach higher frequency levels. Also programs like clokgen, speedfan, ati tool e.t.c should be updated for this mobo. Anyway my second concern was how much would it overclock with my Geil One tccd sticks and my old sli-dr's tweaks didn't work in here and the rams fail to boot above 250 mhz. I knew that it would be hard to achieve 300+ mhz levels but at least I was hoping that it would boot in 270-280 mhz levels. These are my initial observations. Now I'd also like to share with you my final attempt to overclock with my bh5 ram.
By the way.Quote:

Nice experience ..just install windows, drivers and OC - no complications at all :)
I like the layout specially for phase, mosfets don't seems as hot as the SLI-DR, and is jumperless even for using 2 vid cards with Crossfire..
Regarding the OC capacity seems good for the 1st bios ..there is a clear improvement at least with BH5 sticks, need less voltage - with my good old Corsair 3500 I need at least 3.5v to run at 260Mhz 2-5-2-2 in the NForce SLI-DR, in DFI RDX200 only 3.3v is needed. :D
http://pedrorocha.planetaclix.pt/DFI_ATT_2800Stock.jpg
I strongly recomend running the sticks on the orange slots ..
Well not a bad first impression, let's see how it goes when I receive my MasterCard :D
that works for me, i dont really have interest in tccd personally...
New Review:
http://www.vr-zone.com.sg/?i=2893&s=1
i think that review may have sold it for me.
I want it but how long will it take to come up with a new bios. Hoping to see something within the next 1-2 weeks or else I have to buy a SLI-DR.
im personally waiting for it to drop below $200, cant afford it yet, im just a few dollars over budget :(
kyosen did some nice stuff with this board.
http://210.163.215.167/c-board/c-boa...ne;no=3927;id=
Although attempts were made to run at the same memory timings, there are obvious discrepancies. From here: http://www.vr-zone.com.sg/?i=2893&s=9 you can see that the Sandra bandwidth numbers are over 200 MB/s lower on RDX200. Everyone here knows that the chipset has nothing to do with this on the AMD K8 architecture and it's strictly a matter of setting up the memory controller in the cpu. Secondly the fact that the CPU scores are slightly higher on the NF4 board means that the reference clock on the nvidia board is slightly higher or something is different in bios. If everything is set up exactly the same, the system benchmarks come out exactly the same within benchmark error (atleast in Sandra).
The 4% deficit in memory bandwidth and the slightly higher CPU scores on the NF4 board explains why the RDX200 is always slightly slower.

so the new bios from amdfreak's link is help i think ;)
http://valid.x86-secret.com/show_oc.php?id=47659
after 350mhz htt i get lockup :( but ist the first bios update , so lets keep hoping it wil only get beter ;) .
can some wanne els try the new bios to ? then we can see if it dos or not
I like Chipset location better. can lose NB fan unlike NF4 which sits under card.
Need to be cheaper though. $200 is crazy for mobo in this day and age.
Hi,
I also did little testing with DFI Lanparty RDX200 CF-DR and compared the performance to DFI Lanparty nF4 SLI-DR. I used Mushkin Redline XP 4000 memory and the EXACTLY same settings with both boards.
Here are SuperPi 8M results:
DFI Lanparty nF4 SLI-DR
DFI Lanparty UT RDX200 CF-DR
Atleast in my tests CrossFire motherboard performed little better than nF4 board. I'll be doing some more research but my first impression is that this motherboard seems is very good for overclocking. I'll try 4 x 512 MB @ 1T next.
too expensive.
Having big problems with 3D-apps. The computer crashes when I try to run 3D with clocks over 220-230 (depends on app) on the memory. I can run prime and memtest all day long with 10x260 1:1.
Tried both bioses
Specs:
7800GT (tried 81.85 and 81.87, tested 77.72 but when I tried to install it says that it couldn't find any compatible hardware?)
OCZ gold pc3200 (rev3, bh-5 i think)
Settings in bios:
wil test soon for max 3d stabel withe tis bord ;) .
nice test sampsa :slobber:
I am trying the new bios now.
Feel free to post results soon :toast:Quote:

...anyone using 2Gb memory kit (2x1Gb) with this motherboard? Does it like it?
withe the new bios http://us.dfi.com.tw/Support/Downloa...FLAG=B&SITE=US i can do 350htt so low htt i dont think soQuote:

This new bios also seems to help tccd ram do better. I was struggling to go above 280mhz with the initial bios and now I made 300mhz fsb with my Geil One tccd ram sticks.
Anyone has Ballistix results?
cool, sold.
OK, after the release of this new bios and seeing as it apparently fixes some issues, I went ahead and ordered one of these coupled with a X1800XL -- while waiting for sweeter things ;)
The board should be here by tomorrow or monday. The X1800XL has already arrived.
-k0nsl
Im testing the bios, results and thoughts soon. I also opened up all the dram options from 2.38V to 4.15V with the missing steps inbetween.
As soon as i am happy its ok I will post it.
i have some results over at dfi-streets.
Basically, my 2 x 1GB Ballistix are doing 270HTT 1:1 at 2.8v (2.73 smartguardian readings) dual channel with 3-3-3-7-1T timings (everything is on auto, except the timings are set manually). But the everest and sandra readings are quite low. Reads are only at around 5600 MB/s. Remember, that's at 270HTT. At stock, i get about 4200. Don't know what's going on.
As far as the new BIOS goes, it didn't seem to fix much. The board still won't post after exiting the BIOS (saving changes or not) when the system is overclcoked. When it's at stock seetings, the board posts fine with the new BIOS.
And it does occasionally hang for no apparent reasons. At 100% prime95 stable settings, the board will hang at post like 2 out of 10 times. At anything over 270HTT, it becomes unstable during POST. It will hang half the time at post, but once it gets into windows, it's prime95 stable.
even with dividers you get the stability issue?
yeah, it's not ram related. It's not really a stability issue, it's just it won't post half the time. I tried 300HTT x 9 with a 3/2 mem CPU/MEM divier, and the board would not post half the time, but once it did, it was prime95 stable.
So it can do high HTT, it just hangs at POST a lot. I have no idea why.
sounds like youve got a dud maxt
I'll RMA it if that's the case, but it just seems like a BIOS issue, which is obviously in the very beginning stages. I am running rock solid stable at 270HTT right now. It hangs during post maybe 1 or 2 times out of every 10 reboots. But i haven't had a lockup yet gaming, or priming.
The board is definitely not worth 200$ though, not in its current state anyway.
The board really improved with the new 1102 Bios,
Now, booting at 300HTT is not a problem and is superpi stable a 345HTT, as you can see:D
http://pedrorocha.planetaclix.pt/DFI_ATT_345HTT.jpg
This old FX-55 is nothing special in terms of very high HTT, if I remember does not give more on the SLI-DR ..
That was a big improvement just for the 1st bios update, so this motherboard really have a lot of potential :cool:
No problems on exit on bios at all or any other freezing ..
I will try the board with some Opterons and also in phase maybe this weekend :)
Here is a quick test DFI RDX200 CF new Bios + Opteron 144 OEM (CABGE0536) air cooled by an Zalman 7000u
http://pedrorocha.planetaclix.pt/Opt...4_steeping.jpg
SuperPI benchable at this speed :
http://pedrorocha.planetaclix.pt/DFI...on144_3000.jpg
Not bad for a $140 CPU :D
Really big improvement with new Bios, I think it is time to put this moterboard on phase :)
OK, as promised here they are the first benchs with this board on phase ..
Not a prob to mount it on the Vapo LS
http://pedrorocha.planetaclix.pt/DFI_ATI_onVapoLS.jpg
I used this CPU - an CABGE not exactly the best stteping in term of overclocking ..
http://pedrorocha.planetaclix.pt/CPU_stepping.jpg
And I imediatly get this SuperPI benchable..with only 1.64v on the cpu core ..s
http://pedrorocha.planetaclix.pt/DFI...on150_3450.jpg
:nuts: :nuts:
I'm really amazed, becuase with this CPU on this Vapo on the DFI SLI DR (Nforce4) I need at least 1.75v on the core to get this speed SuperPI benchable, as you can see..
http://pedrorocha.planetaclix.pt/Opteron150_3451.jpg
This means that DFI RDX200 CF with the new Bios needs a lot less voltage on the CPU core to get the same speed Superpi benchable
This motherboard really have great OC potential ..an this as just the 1st Bios upgrade :D
Bravo DFI ..good work :cool:
That makes these boards look much more appealing now Pedro. Thanks for sharing. :toast:
Well lets see how things go as time goes on
didt some 3dmarking today :D .

the x800GTO² @ 16pipes is good card but i have a bad oc core :( ,
but soon some x1800xt benches ;) .
noting tweakt . my cpu fly's on this bord :banana: , idd nice work dfi
OK. I'm convinced with this board - 3.500Mhz SuperPI bench with this Opteron 150 on the Vapo.. :)
http://pedrorocha.planetaclix.pt/DFI...on150_3500.jpg
No way I can do this with same cpu and cooling with the SLI D, the maximum was around 3.460 with much more voltage - clear advantage for the DFI RDX200 :cool:
excellent results Pedro, Does more volts help you at all? Can you show a ram timings shot or is it the same as the previous screenie? Looks like Oskar has really outdone himself. I think you just sold me on this board. With the delay of the Expert and Grouper's performance not beating DFI's flavor so far, I'll just say, screw it, I can't wait forever, ordering now, hehe. Not like I can't just sell it later anyway if one of those other ones proves to be better. This round of ATI based boards, very exciting times indeed, props to ati too.
there's a noticeable difference between SG and cpuz looking at the cpu voltage
4 phase power = me like.
Yes, CPU-z does not read the core voltage correctly with this board - even with new 1.3.1 version always read 1.450V, this need to be fixed :(Quote:

So i was bored (i mean really bored) after getting this thing going. I made a few little tweaks for SmartGuardian.
http://home.comcast.net/~butterfry/RDX.ITESG.jpg
Could someone with a proper multimeter calibrate the 12 and 5v rails for me? If you guys want this .exe and ini file let me know.

You guys might also wanna check out how Grouper is doin...... :D
Nice.
Now if only they sold them in the US... :rolleyes:

There was some rumors that the mobo can minimize or even cure the problem, I never beliave it.
I have serious doubts that any board can resolve the issue, it is a problem inherent to CPU, not motherboard / chipset related..
I wish I was wrong ..spend a lot of money in a FX-57 that give me disastrous results in the cascade at -100ºc or even less .. :mad:
Anyway I will test this mobo on Ricky's cascade in the next days, I will let know the results :cool:

As you chill a cpu the drive strength from the memory controller increases, so you start overdriving the memory.
So, you have to weaken the drive, you can ONLY do this on the motherboard. You have to switch in resistors that alter the drive weaker or stronger depending on the resistance used. This is also one of the ways you tune a motherboard to clock ram well or a specific type of ram..IE...TCCD etc.
Now its not a full on cure to the cpu overdriving the ram, but if tweaked correctly it will allow a higher fsb to be reached.
So...Cold bug is not a serious issue, its just because the cpu's are not designed to run -50 from the onset, but to say nothing can be done on the motherboard is not true....the only way to even half fix the issue is with tweaks on the motherboard or design the cpu to run at -50 or lower.
Testing at ATI of Gruper and halibut proved this theory correct, if it didn't work we would not have designed it into the board. It won't work for everyone as every cpu is different, but it will help.
just out of curiousity,
howcome do some cpu cores, like clawhammer, and not like San diego, work at lower temperatures?
thats a question for amd bud, no one here will have the absloute answer for that oneQuote:

will the RDX200 be able to clock TCCD as good as UTT with new bios updates, or is there someway to hardware design the mobo the be more efficient (if thats the word) with certain types of memory?
