Worst that can happen is be told no

ATI gave me the figures although they are peak i feel. I can tell you under 100% memory load im only seeing 35C max on any component around the vdimm section.

Peak maybe... or maybe that inductor is taller than it looks

/curious cat mode on

100% load being what? 4 double-sided DIMMs @ Vmem? Mem Type? FSB? running?

/curious cat mode off <--- almost impossible

so you can only go .05 V over stock??!?! or am I having a stupidity attack?

i think it kinda depends on the stick, but i hope what you're saying is wrong.
also, it would help to know what voltage that 40A rating is at. for all we know, it could be 40A at 3v, which should be enough

Digital enhancement

No PNs on the semi's tho

**Zebo** · 05-31-2005, 08:22 PM

So does ATI have better mem performance read/write like you said it would in an earlier preview?

I guess taste is personel but that cream color looks like snot, no thanks.

Here is where it's at

Seeing that DFI's board will do Xfire without mastercard, do you think Sapphire's grouper version of Xfire can do it also ?
If the boards hit the street before the mastercards then all will rush to get the one that can do it without mastercard.
When mastercards comes to Sweden you guys in US is already running dual r520 or something.
I think..

I really like the adition of a MOSFET cooler with standard mounting pins.

**Squid_Spit** · 06-01-2005, 02:11 AM

Looks fully packed with all the necessary options, but imo physically it looks pretty darn ugly.

**LoKi2k** · 06-01-2005, 02:16 AM

omg! gimme more!

what is about the vcore? where is the max?

**Tony** · 06-01-2005, 02:45 AM

max Vcore is +0.3V over max VID..its in the pics

board color can change, the RD480 was black and red so Sapphire could end up using the same for this also.

**babyelf** · 06-01-2005, 02:51 AM

lol bitoe.. the vcore +0.3V is not linked properly.. ..

i'm with him.. white is sexehhh

**eva2000** · 06-01-2005, 03:27 AM

very nice Tony... getting moving on some ram overclocking ASAP

Attached is a little chart from my previous power allocation calcs for four 512MB DIMMs.

With a 90% efficient switcher circuit, worst case from the 5V rail would be ~19 Amps.

I think..

Without a Compositing Engine chip (this chip synchronizes the frames) on either of the graphic cards you will only be able to see half of the rendered images. In other words, the screen would just fllcker although benchmarks would still report a higher score or average FPS.

You will need a Master card for Crossfire to function properly.

4v VDIMM ON THIS CONFIRMED !!!!!!!!!!!

**Tony** · 06-01-2005, 06:48 AM

Whats with these venice CPU's, its real hard to clock TCCD with the one i have here?

2901T and over 300 2T both with good bandwidth, are peeps still having to run 2T with venice or was it just a bad week code etc?

**WeStSiDePLaYa** · 06-01-2005, 06:51 AM

im tottally in love with the sink on the mosfets idea being the same as a NB. would be sooo easy to switch to better TIM, or even put a better hsu on there, or maybe even watercooling?!?!

Around six months ago ATI approached me for input with regard to what i would like to see on a motherboard. i suggested many of the features you see that are on this board. These included:

The ability to water cool the mosfets etc.
Well engineered Vdimm power regulation
VTT tweaks
Multiple voltage options
totally seperate clocks for PCIE, sata etc etc
and a host of other enhancements to create a "pure" enthusiast board

. Now, its a board you have to tweak, but its really worth while seeing how you can dial in stability etc.

**FireDragon** · 06-01-2005, 07:09 AM

THIS IS GREAT now just waiting for the DFI board!!!! This is going to be crazy and if you ask me drive NF4 into the ground!!!
