Hi, i jz bought DFI RD200, but i can't use my teamgroup TCCD RAM on it.. izzit i need to upgrade the BIOS? I try to use dual channel cannot boot up, get beeping sound. I try configure as single channel, it is working... i know tat DFI is a picky mobo, so anyone can share his/her solutions?

Haha...

The RDX200 board is the worst board ever manufactured by DFI.Flashing bios is a must for DFI boards.

Har, really, damn lo ... luckily i bought it at cheap price so won't be disappointed...
So anyone know where can i find the Mod-BIOS for the RDX200...?

Thanks bro..

How much you bought?

juz wondering...hv u tried the other ram slots?
coz i've had those prob when
i used my mushkin tccd wit my ultra-d
tried many combination n lastly those
2 orange slots works for me...maybe it could for u

as far as i know TCCD ram need to be in the orange slot and BH-5 chip need to be in yellow slot..

before flashing to new BIOS, try suggestion made by this poster, well, i'm using TCCD but on SLI-DR, at first, i plugged-in to yellow slot, it won't boot after swapped to orange slot, it boot.

wonder rd200 is whether same as sli-dr expert since both boards layout is almost identical.

well, I just want to correct what mnemonic_80 said.

Orange for TCCD, yellow for BH5 only applied to NF4 ultra-d/sli-d/sli-dr, but not to Expert and Venus.

if you put BH5 into yellow slot on Expert and go oc it, even a bit, you'll notice something during loading windows.

Gsan, sorry for my noob question, but why is it so? (i mean the orange and yellow thing)
Nothing was stated in the manuals on this.
Luckily i saw this, if not i would think it's the ram fault.

actually, for nf4 non expert or venus, both yellow or orange slot work fine for tccd & bh5, but bh5 on orange and tccd on yellow can be overclocked better.

but for expert (not sure about venus), you cant overclock well if you put bh5 on yellow slot.

yellow slot = better for BH-5

orange slot = for TCCD

yeah....already make an experiment....

but just like gsan mention (thanx for correcting me ).. it's just for nf4 ultra-d, sli-d n sli-dr... but for expert board if u put bh-5 chip into yellow slot.. something strange will come out on ur screen.. even when u run memtest, i've tested it with my expert board.. but dunno for venus

You ought to have checked up with DFI for compatibility mate...

Hmm...gotta try it out by running my TCCD in the yellow slots.
See if anything happens...
Wierd, wierd...Going to do some googling on this...hehe...

Yellow slot won't work at all for me.

Tried BH5,TCCD and UCCC before,on yellow slot won't boot at all.It will only boot on Orange slot.But it depends la......you guys can't just say Yellow slot = BH5 and Orange slot = TCCD.Only n00b will say like that.Best way is you try which slot works best for you.You don't try,you won't know.

yo bro....not all newbies is noob....
said like that coz already try it ar on my SLi D.....

Just tested booting my Ultra-d for the 1st time.
Used Kingston KVR to test, and it would not even boot on the yellow slot, but on the orange slot, it works.
Btw, i don't know what chips r those kingstons running on as they run on kingston rebranded chips.

not sure that how far you measure "wont boot at all" ? you tried it more than 50 times? or just 10 times?

I cannot say that every dfi nf4 also act weird like what I experienced, but what I noticed was I used ultra-d rev.AD0 and rev.AE1, sli-dr expert, all have the same problem. I owned 4 BH5s and 2 BH6s, when I installed in the same yellow slot, sometime it can boot easily, sometime cannot, even I tried till wanna give up also like that, but at last can booting up (thanks to my patient ).

@@shole!!!!You think I'm stupid like you to boot more 50 Times?Ask your our grandfather to boot more than 50times for you.

For me,I have tried both SLI-DR and SLI-DR eXpert,never in history in my life that I can boot with Yellow slot.It depends on our luck whether the board will boot on yellow slot.

You are completely a N00B!!

come on people....
dont be like this.....not good to say people noob or not...dont judge someone like that...
maybe some DFI boards need to be flashed the bios for the RAM compatibality.....
but for me...when im using HyperX....at the yellow slot can boot and tweak easily....but at the orange slot just can boot but cannot tweak....sometimes it cant boot...
but when using Team XTreem...just the orange slot works for me......the yellow one cant...

maybe not all board have the same prob.....in a 100 unit....maybe just 10 have the same problem....

OKok......Sorry to everyone if my words seems to be harsh.Yup you are right,only some boards like that and it has knowned world-wide that DFI is very picky in ram stuffs.

Haha. sorry for disappear, i bought the mobo below RM400...

Okok i think tis weekend i will test it out, coz X'mas holiday.. lol Merry X'mas

Anyway thanks for sharing your experiences coz i jz new in DFI... hahaha... i jz let my pc to let my sister dl taiwan show... no time to test it, by tis weekend will try out... Thanks

be sure to inform us the result............

woow...you're lucky ya, get a superb mobo with cheap price

Dude, don't simply shoot DFI like that lah.
Have you tested out the RDX200 yet?
Well, tell you something... although the board has some issues, I find this board pretty stable for me as I've been running it at 312HTT for almost a year now. My Opty is clocked to 2.8GHz and I have 2x1GB of Corsair XMS 4400PRO running at 255MHz 1T. All this is in my work rig and it runs 24/7... Heck, I even ran SLI on this CrossFire motherboard. And for the record, the board was not modded whatsoever.

As for the thread starter, I can tell you that this board is a little picky with certian TCCDs. I had some issues trying to get TeamGroup modules to do 250MHz on this board... so it could be the modules. However, my Corsair 2x256MB TCCD works great with this board and I can clock the ram to 291MHz at 2.5-4-4-8-1T... and all this was Prime Stable for a full 20hours.

FYI, I'm on BIOS dated 12/23/2005. Also, try playing with the drive strenghts.

Although the CFX3200 is the ultimate s939 board, the RDX200 is just slightly below the elder brother.

Edit: ncool15, FYI my colleague (MetalZone) has an Ultra-D, which is same as SLI-D or SLI-DR (not Expert), and he could actually boot in Yellow slots. There's even some users having better stability/OC on yellow slots. This is totally depends on the CPU and RAM, as the mem ctrl is on the CPU. So, next time please get your facts right and don't call others with such harsh words. This is a public forum, and seeing you post like that shows who's "the real n00b".
Better edit your post before you get warned by the mods or admin.

dude, do u have any idea how gud an overclocker he's ? mind ya words pls

to claim an gud achiever as a noob really show that u're a noob yaself...

juz got a pair of ddr600 and put it in the yellow slot...
got no problem and still can boot into windows...
but onli can run on 2T timing... 1T cannot boot...
still have to do somemore research on this ram...

for tccd user... on ATI chipset mobo...
use the orange slot and try these setting on your mobo...

you can try to adjust the FSB... but the DRAM setting juz keep it the way it is...

this setting is mainly for CFX3200 user...

juz Oced my x2 to 2.7ghz...
will try to prime later on...

got help from other overseas OCer that use the same spec as me

update....
the setting is still not stable...

so now does the setting is perfect???

erm, the booting is due to a weird proc mem controller problems...
me myself facing problem when using gsan's 3200+ to boot for my 3500LL 2x1gb.
but it have no conflict with all tccd i have tested...
now, issue is not how u cooked ur mobo...
but what ur whole system do...
