Remember that this is in CCC, as Rivatuner and ATItool don't support these cards yet.
I have watercooling.

With RivaTuner / ATItool support core should go higher?

ATI allows for voltage control through the BIOS?

LOL I wonder if they'd notice half the heat sink missing.... I really wanna just mod my 4850 with half the VRAM covered by the heatsink like many people are doing, and throw up Accelero on there. But I want to keep my warranty with VisionTek..

You'll still need to cool the MOSFETs on the back of the card, they get roasty like the X1900 series, and also ruin overclocks like the X1900 series.

But yes, there should be voltage support and with that, I bet we'll see 900+ core clocks like on the HD38 series.

Screw the warranty, it's fun hacking it up.

I was looking at getting the ASUS P5Q Pro which can be bundled with the $194.99 ASUS 4850 which gets you a $30 discount as well as a $30 MIR.

I am just really sure if the 4850 is worth getting. I don't really use my 8800GT. The only thing I go crazy on with graphics, gaming video cards can't help.

$285 for a HD4850 and a P45 motherboard sounds like a good deal to me.

Moots:

What Voltage is your card running at? After checking my stock VisionTek BIOS, mine is running at 1.046/1.084v which might explain the poor overclocks many Visiontek cards are getting (I can hit 700 Core, but passing 1050/1060 on the memory starts to artifact).

Where are you reading the voltage from? The card or software?

Did a BIOS dump with GPU-Z and loaded it up with Radeon BIOS Editor to check the stock volts (I know they aren't actual) as they are apparently the lowest of the other ATI vendors.

Newest version of which? Using RBE 1.11, ATIWinFlash 2.0.1.2 and GPU-Z .2.5.

If you were talking about BIOS, I was thinking of adding some more volts to it in RBE (wasn't going to go for 1.2, which is the max for 4850 through soft-mod, but probably 1.1-1.125).
