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:

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:

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 .
http://service.futuremark.com/compare?3dm05=1404611
http://service.futuremark.com/compare?2k3=4377817
http://service.futuremark.com/compare?2k1=8779662
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:

you tested?
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.
-butter
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:
Which G.skill sticks are you running? LE's?Quote:

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:

onto not hijacking a thread...
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?
Tony,
On the RDX200 you have a drive strength range from 1-15 .
WHat's the strongest/weakest value?
I haven't played with all the drive strength settings yet , 7 seems to be a good 'default' for my board/memory (tried TCCD and BH-5)
thanks
some 130's had the cold bug also, its all probably do to memory controllr strength etcQuote:

Oskar is not telling either im afaid :confused:
Pedro are you running that rig 24/7 wit the LS or is that just for benching? I was interested in buying a RDX200 for my 24/7 gaming rig. Going with a FX-57 2x1gb ballistix and 2x74gb raptors raid0. Would like 3ghz atleast on water and maybe 3.4 on modded Vapo LS for 24/7. Will this be compatible or should I just go with the Expert?
I threw my week 32 FX57 on this board using my cascade. It was useless, I used all drive strengths and the CPU just couldn't handle the cold.Quote:

It’s all about the CPU.

It's too bad we have yet to see a good compare with the same cold bugged CPU on NF4/RS480 yet. I'd do it if I had a cascade.
What kind of cooling do you use for testing this broad range of CPUs? :DQuote:

really weird results.
i can't seem to get it identify any IDE HDD i have.
memory OC:
Kingston HyperX pc3200 (old school BH5, benchable @ 270MHz 2x512MB)
Venice 3000+ E6
263 everything runs perfect
264 MHz and i can't even make it to memtest...
no matter what drive strength, no matter what voltage, refresh rates, or any other timming i change
in my DFI ultra-D i could easily memtest up to 269-270.
im definately looking forward to a new BIOS!

I assume you would tweak the memory before the CPU gets cold. That’s what I tried doing anyway, with no success.Quote:

Now I do know some CPU's just won't boot below a certain temp, so the way to test is to boot at say -30, set the ram speed and drive strength, boot to windows and clock higher and reduce the temps while in windows.
For those who chill and have no luck booting probably nothing will help, but for those who can boot but have to run low ram speeds this should help you clock higher.
The new ATI System Manger is a very nice tool to the DFI RDX200 CF-DR motherboard ..here is a screen:
http://pedrorocha.planetaclix.pt/DFI...ATI_SysMan.jpg
They are inclued in the Saphire Grouper ATI Chipset driver set, you can download here - unzip the file, and just install the from the ATI System Manger directory ..
In the ATI System Manger you can control almost everithing ..CPU speed, voltages, and all memory timmings, realy nice tool :D
Enjoy it :toast:
Be very careful with this tool on boards it wasn't designed for like RDX200. The results of doing so are unknown. The clocking stuff and A64 memory stuff should be okay but DO NOT CHANGE THE VOLTAGES on a board it wasn't designed for. The end result of doing so is unknown.

I am happy with this board. But there are some software issues. For example when will there be a cpu-z version showing the correct vcore voltage? Ati tool is not working. Clockgen is still in beta version. Speedfan program just locks the computer when started. Do you people know that among these problems any solved?
As for the drive strengths in bios I think I read somewhere that 1-8 for using two dimm sticks and 9-15 for four sticks.
with the last bios, this board has better results than a dfi nf4?
It's hard to say whether it's better than my old nf4 sli-dr but it's definitely improved by means of overclocking with the latest bios. High htt problem is now history and tccd ram speed has been improved. I can use my Geil One Tccd ram with 300mhz 2.5-4-3-7 timings with this bios. Another cool thing is that this board works cooler than the old nf4.
I have yet to exceed 270mhz stable. I wanted to atleast reach 280-300Mhz on my 3200+
-k0nsl
are there any bios guide for tccds out there for this board?
Guys I'm trying to use 4 dimms at 1T but couldn't suceed in doing it yet. I used all drive strengths from 7-15 but no use. Also data strength 1 and 2. Tref at 3072 and 4708 e.t.c. I also used Tony's exact same timings on the second page of this topic but still it's no use. I paired a couple of Geil One Tccd sticks with a couple of Patriot Pc4800xblk. Do they have to be from the same vendor? Also I tried with 4 bh5 ram and couldn't make it. Can you tell me what the problem could be?
When will DFI release new bios? :cool:
Here's the latest beta BIOS 12/12:

The San Diego seems to be the Fastest/ Best overclocker on this board. The Venice 3800 worked Better on the Asus SLI Deluxe 2.9G stable only 2.8G on the RDX200. Board was the Only Difference.
hI all probly bring this tread out of the dead. but im setting up a RDX200. I like to use OccT for first test and like the read outs.I use mbm5 for Occt on my nf3 250 but it dont work for this board so i tryed speedfan and it dont work for me eather can anyone help me with this so i can get OccT working ?
ok now answer for that last one .
How about can anyone rember witch of tonys last two bios worked the best for tccd ?
