DFI RDX200 CF-DR First look

I have to admit so far the bios is not at all friendly if I change too many settings it wont boot, I am using tccd.
I have to run the tccd at 2.5/4/4/8
And this tccd does 300 at 2.5/4/3/5

Set Drive strength to 7,8, or 9...DATA drive to 100% I think.

OK, doing some 05 benching now using x600xt.
So far so good.
Just using some 2.256 sticks to get going.

Ok quick recap so far.
Using dimm 1 and 3 no go on 2and 4.
Using gskill 2*256mb 4800LA
OCZ 520w
e3 3000+
maxtor 20g
regular cd drive
x600xt


Installation of windows went down without a problem.
I cant seem to tighten the timings on the memory.
(Board would not boot with bh5 seems the mem defaults to 2.6v not enough for bh5.)
Have to use 2.5/4/4/8/11/16
Board runs very fast at stock and currently benching 05 getting some real good scores.
not a single crash so far I have reached 240fsb so far running 1:1.

So use slots 2+4. This can be fixed with a bios Im sure as it was on the dfi nf4 some bios's like 1+3 others 2+4 best :)

deff slots 2=4 1t command is alot faster going from 1t to 2t is like running your ram at 166mhz instead of 200mhz its that big a hit

THANKS

i thougt it had to do with the memory controller?
if you run 2 sticks in dual channel the memory controller is using a 128bit bus and pretty much addresses the memory as if it was one stick, if you use 2 sticks without running dual channel the memory controller is using a 64bit bus for two sticks, if you run dual channel with 4 sticks then its using a 64bit bus for each pair of sticks.

the way tony explained it to me command rate is pretty much the tolerance the chipset has for a reply from the memory. the lower the less tolerance there is and the faster the memory has to reply, with 1t the chipset sends a request and waits (one clockcycle?) for a reply, with 2t it waits another clockcycle for a reply from the memory. and it sends a second request if it didnt get a reply after the first clockcycle is over, but im not sure if i got that one right.

not to bash the anand review but dont you guys think it would be wise to mention that the 4x1t feature that they talk about the whole review doesnt work with bh-5?

IIRC, they mentioned it....

Micron works though, which is nice.

tis is whit samsung tccd chips just for cpu max to morow il do some 300+ ;)

2x512 /2x1024 ya want 1t so use 2-4slots
4x512 /4x1024 ya want 2t for stabilty so since your forced to use slots 1-3 also you should run at 2t command

and yes 2t make the cpu "WAIT" an extra cycle that cycle is like running
2x512 at ddr400 2t
vs
2x512 at ddr333 1t

its a big 'wait state'

---

thx for clearing that up :)
hmmm so is this 128bit 64bit channel thing wrong then?
do you know how the wait cycle is timed? is it always of the same length or does the cpu speed, memory speed or ht speed influence it?

about your cpu ocing worse, does it depend on the vcore?
i mean does it oc the same with 1.4v, slightly less with 1.5v and a lot less with 1.55v? do you have notes of how that cpu oced with les vcore so you could check that out?

Im still having major problems when overclocking. Upgraded the chipset cooling to water cooling today "not that temps where high on chipset" also swapped out my venice 3000+ for a fx-53 Claw and tried my maxtor ata133 drive and its not helping me.

il try my utt bh-5 to , yes i know the timings are crappy ;)

Got some scores coming up in a couple hours.

Use only orange slots with 2 dimms, yellow when you run 4 dimms. you have to set LDT manually, auto does NOT work like the NF4.

TRC is very agressive, set TRFC to 24. Drive strength at 4 5 6 7 8 all work but you have to play with read preamble and max aync. Im running 6 and 9 Rgone is rinning 5 and 8 so try these.

Jason, put TCCD in your board and run the settings I posted, if the board will not do 270+ then you may have to swap it, i have a feeling its just settings though.

PM me your email addy and I will mail a bios i tweaked, i can not share the beta bios files i have but this should get you at 270+ easy with good TCCD.

I noticed I have to run bh5 in slots 2 and 4 they willnot run in 1 and 3.
The tccd likes 1 and 3 but not 2 and 4.
I have hit a wall at 250 for benching, I can get to 270 for regular stuff but not benching.

I have to say this board has really surprised me, their are obvious issues but it is a very strong in the benching category as it just allowed to take the trifecta using an x600xt.
I seem to have hit a wall at 250, dont know why but will work on tonite or tomorrow.

Here are some more screenshots :p:
The funny thing is this was all done on air no vmods nothing, the chipset has promise, a better bios and major improvements will be made :cool:

I have only been using 2 dimms just to see how the board reacts will start using 4 dimms tomorrow.
It games very nicely also.
Aside from teh sata 2 an acceptable board, but for a first board it will be difficult.

Going to try that tonite will see how things go.

I hope i can get mine up and running:(

jason i tried another psu but it didn't change the problem :)

i don't know whether this guy from Germany is a visitor here but his results are looking pretty damn good so far with a nice Opteron CPU and this mobo ;)

Tony......any updates on DFI CF-BT and DFI's Grouper :)

MickeyMouse i have some nice screens running 250mhz 2-2-2-5 512X2 .

now backt to run some more tests
cpu-z reads mij vcore wrong so here a screen withe vcore and stuf , i dont think my cpu temps are right but wen i feel the blok its cold ?

Heres after play with it for a while.....I;m happy that my Zippy 700W can power it up @ 3.6V Vdimm :)

http://img467.imageshack.us/img467/6...shot0041pa.jpg

So, with the right bios setting it will fly with any AMD 64 core and utt/bh5 :)
Too bad we still have to wait for clockgen....Hurry up Frank :)

Somone can help with new bios? I really appreciated it, Thanks :)

Here is my latest result of LN2 cooling :)

SuperPI/mod1.4 1M: 22.531s@3720MHz
SuperPI/mod1.4 8M: 4m07.000s@3703MHz
FX-57 0516WPMW(IHS removed), Vcore=1.795V
Winbond BH-5 UTT(?) 512MB x2, Vdimm=3.689V

owe to a nice copper container, KurinuiteMasu-Pro4,
many thanks to TAM :toast:

With ACPI Multi Processor PC setting,
-115deg(C) is safe, -120deg(C) is risky(=means freeze), in my case.

my cpu fly's on this bort , tis is not tweakt standart os
