What is the difference between CF-DR and CF-BT? :)
i don't think 4x DDR400 1T is possible...Quote:

Anyone have any idea what the stock clocks are on this card? Neither ATI online nor Allstarshop bother to mention this. If they are clocked like XL or even XT I won't bother.Quote:

The X850 Crossfire card is clocked at X850 XT speeds. I have a production one. (Not a non-Qual) I ran it with a X850 XT PE. In Rivatuner the cards show up seperately at their respective clocks. (520,540 and 540,590) The interesting thing was I could OC the cards individually. My X850 CF card I raised the core/mem and scores increased. If you can OC the cards to their optimal speeds indivially that would be a major advantage over SLI. <----it seems you can :DQuote:

Hey Jason,
He's still working on it ?? :confused:Quote:
Wheres Macci's 270mhz fsb runs?
Still a Mystery officially anyway. Current rumours put the blame on old bad yielding core (XL) vs new good yields core (XT).Quote:
If all thats different on the XL vs XT is the 1.4ns ddr vs the 1.2ns and cooler/clocks and the cards can run so high without being a cherry picked cores why is there no XT's on the market yet just XL's?
Google "dfi cf-dr" and you'll find a few sites giving pre-orders...even though they were originally set for release in July/August.Quote:
I see Crossfire x850's, but where are the crossfire mobo's?
Lestat already previewed the cf-dr...here. Also, when's eta on your XL ? :D Answer to other questions below :)

Don't know the reason for that. Imho it was because CPU under dry ice. I even tried with two different PSUs and I just couldn't get it boot. With our custom made 1320W PSU the red lights on mobo were on but the power button didn't react at all. With Antec 550W and Tagan 480W I got the board running but it sure ran really strange.. beeper was making low noise, CPU and PSU fans spinned strange, they kinda couldn't... I really couldn't tell what was wrong.. maybe some water around the socket, which I really doubt because we insulated everything just like before and after I changed to DFI's nF4-SLI-DR we had system running just fine next 5 hours. I fired up the Sapphire's Crossfire board next day and it worked just fine..Quote:

I'll try Sapphire PURE CrossFire motherboard next week again with LN2.
ATI does not plan on 1t 4 banks DDR400+. DFI does (At least that was what I was told.). The 939 controller is limited to DDR400 too but everyone here has accepted that it is can run higher. Before we dismiss the claim how about we wait till the Mobos are in our hands. We all accept the capabilities of the DFI NF4 SLI-DR. Some of the things it can do would be considered "way out of spec". Soon all will be be known.Quote:

I agree, but pls keep in mind that chill pills cost a dollar at walmart...oh srry, i meant...pls keep in mind that Macci must be busy with loads of testing and benchmarks going through scores of drivers and programs on various different types of cooling for the XT launch :)Quote:
but s*%t come on onkly select clockers have the HW they wait to show it off, then do it right.
Perkam
I dont get why you need macci to do all that :confused: Wouldn't asking grayskull, sampsa or AACDirect nicely do the trick? ;)Quote:

If you look at the Crossfire boards, they've had problems from day 1. I'm sorry, but enough IS enough.
As far as I'm concerned, when I see X1800XT's on store shelves, it won't be a paper launch.
About the X1800XT's...The core is the same for the XL...We know that...The only difference is the memory, and the cooling. Now, take into account that the XL runs EASILY available 1.4ns IC's, that's no problem. I have a feeling that yields are very low on 1.2ns Samsung IC's right now, and ATi is either finally getting shipment, or making another paper launch to shut everyone up.
Someone can come flame me if they like, but I'm sorry, ATi dropped the ball this time around...Does anyone remember the FX5800???
PS Perkam...We don't take chill pills...Red Bull works much better ;)

Do you think he told me the board could do 4 X DDR400 1T just so you could fly off the handle? Damn just wait till the facts are known.
Also how many motherboards have you designed and built? I tend to believe Mr. Wu and DFI have a little more knowlege than you and me combined. If they say it is possible why shouldn't we assume that it can be? I am supposed to have a board next week. I will test to see if the board can do it and planned on posting results. Until then drink a Redbull and chill. (BTW If Greyskull would like to post his opinion.....he WOULD know if it is possible.)
As for Macci. After meeting him. One thing is that he is very meticulous. My guess is that he is concentrating on videocard OC. Once he has that figured out then he will look to the MB. Any way Macci is not a trained monkey to do tricks for our amusement. When it gets done I am sure the results will be worth the wait.
One thing I have liked about the forum is the open minds and lack of "BLA BLA you can't do that....ATI sucks...NV sucks....you suck type of posts."

For the record, i think a lot of what you say about people blindly following is true. These XI800 do look great, but until the general public get them, i can't really be that excited.
I remember when 7800gtx was LAUNCHED (and available on the same day) everyone was nuts about them, and a ton of info was known. Even though i didn't have one, it still made my month. These have just gone off with an empty 'poof'. Only macci, sampsa and some others have them, and i guess ATI just announced it now and got a few samples out to keep people entirely going to the green side.
That is not true :nono:Quote:

I think it's true.

fair enough, but it still means another months wait for the ATI high end.Quote:

I didn't try too hard because that wasn't what I was trying to do but I don't see any restriction in the A64 to prevent this from working.
I *do* know it will take special layout considerations and the right settings. If anyone will figure it out, I'd bet DFI will do it first.
Based on what I've seen with my own eyes I'd say it's entirely possible that DDR400 1T could work with 4 sticks.
But let's just wait and see before anyone starts doubting it.

One thing that I do know for sure, motherboard design will affect this.

I'm looking forward to the dfi crossfire solution too, but I can buy an sli board NOW for less than $150 :( ... I'm sure the same cannot be said of crossfire, at least in 2005 I'm sure.

You claim to know more than two company officials from two top multi-million dollar corporations. Pls show us some proof of your statement for us to believe you.Quote:
