I found 1 store, selling 8000UL for € 270,- ( sold out :( )
Corsair 8500 for: € 241,-

UPDATE: My weekend-long qual test on 4x512 MB @ 1066 failed after 6 hours, meaning that some part of the test bench was not able to run at that speed, my guess would be that it's a load issue on the memory controller.

Hardware:
P5WD2-E w 0402 BIOS
955X processor
4x CM2X512-8500 (2.2V @ 1066 @ 5-5-5-15)
Fan on northbridge & mosfets, fan on RAM, Nautilus 500 on CPU
Silverstone Zeus 650W PSU


Both sets of modules pass just fine when there's only 2 modules, but up it to 4 and the system is less than 100% stable. Since 1066 isn't an official JEDEC spec and isn't supported by Intel yet officially, I am not surprised. I'd imagine that we'll see a 1066 in Q3/Q4 this year if I had to guess, and probably 1200 next year sometime, but anything after 1200 would probably be DDR3.

This is all hypothesis by me, though, I am not privy to the actual plans of Intel and Jedec and now, I guess, AMD's determination on what they're launching AM2 at, speed wise.

Maybe you could try a little higher chipset voltage (if you didn't already do that)

Chipset voltage was maxed. Some boards might be able to do it, maybe if we had watercooling on it...

yeah,the 8000UL are pretty good. I found a pair that could do 400 3-2-2 in Pi stable. ANd i dont know if the old Corsai 5400 can do that.

How much voltage for 400 3-2-2 stable?

2.55
but stable only in pi 1mb and Lobby High

This My 8000UL stable spi 16m with vdim 2,2volt.
