Well, I found something that might qualify...hehehe.

The bulk Sapphire Atlantis 9600XT's at zipzoomfly.com are shipping with 2.8ns samsung. The memory label is as follows:

Samsung 337
K4D263238E-6C2A

2A meaning 2.86ns or 350MHz. This memory I believe also comes on the 9800Pro cards. From the datasheet:
K4D263238E-GC25 400MHz 800Mbps/pin SSTL_2 (VDD/VDDQ=2.8V) 144-Ball FBGA

K4D263238E-GC2A 350MHz 700Mbps/pin SSTL_2 (VDD/VDDQ=2.5V)

K4D263238E-GC33 300MHz 600Mbps/pin SSTL_2 (VDD/VDDQ=2.5V)

K4D263238E-GC36 275MHz 550Mbps/pin SSTL_2 (VDD/VDDQ=2.5V)

K4D263238E-GC40 250MHz 500Mbps/pin SSTL_2 (VDD/VDDQ=2.5V)

K4D263238E-GC45 222MHz 444Mbps/pin SSTL_2 (VDD/VDDQ=2.5V)

We can see that 2A is indeed 2.86ns at 2.5v. To me this means that if we volt-modded to 2.8v, we have a chance of going to or over 400MHz DDR. That is really cool. Some of this ram goes to that speed anyway without volt mods, so this is stacking up to be a pretty decent card at this point! When I get my heatsinks in order, I'll let you know what I did with this card without mods. :)

Hell yeah. Looks like that's where I'm headed. I'm holding off another day until I hear back from New Egg, Sapphire and Zipzoomfly. That's a killer deal you got dude. Isn't the memory running at 340mhz stock anyway?

There are two different versions of the XT from Sapphire.

They have ones running 300MHz DDR and 325Mhz DDR.

If you can get these to 400MHz then that is pretty nice.

For mine the stock is 500/325. That's 25MHz under it's rated speed....hehehe. I'll grab some sinks and around the 26th I'll get to work on the card and see what it's capable of. I'm almost positive I can hit 375, and maybe 400, with stock voltage. If you have a choice, the 500/325 are what you want, they'll have the 2.86ns RAM I'm sure. The cool thing was this card was being sold as 500/600, but I got 500/650, sweet.

Are you sure it isn't 532MHz? I have only seen 500/600 and the 532/650s


You say you bought one that runs at 500/650?
