Can I use more than 2 Sticks with the new A64 rev E A.K.A venice?

Did anyone try to use 4 sticks at 400fsb with the new Venice?

You can. I believe 2T is needed though.

agree.

In short no, they didnt upgrade the controller as speculated. All in all Venice is identical to Winchester (venice has sse3 and other minor tweeks)

Link?

Tweaks which include better memory handling at DDR400 speeds.

I'm curious about this as well. Since I plan on running 4gigs of ram using 4x 1gig modules. I also think more of the testing web sites should test the motherboards at their maximum capacity, since if it can do that, it can probably do lesser capacities that everyone uses as well or better. But if it can't, then that's as good as false advertising.

And all the motherboards in recent memory have supposedly supported 4gigs of ram, but no one has tested them using 4 gigs.

I agree, the results of such a test would be a major factor in deciding on my next board.

OK, to clear up the discussion here, you CAN run 4 sticks of memory at 400 MHZ on a venice... You can also do this on a Winchester (I should know, since I am doing it right now). The caveat is that it imposes a 2T command rate, which is somewhat of a performance hit (how much of a hit is still being debated in other threads here on anandtech). Venice will NOT run 4 sticks of RAM any differently than Winchester does. With either Venice or Winchester, when you run 4 sticks of 400 MHZ DDR at once, the board initially clocks them at 2T at 333MHZ. You can easily bump the speed back to 400MHZ in BIOS without problems, but you will NOT be able to run 4 Sticks of DDR400 at full speed at 1T. You MAY be able to get your RAM to 1T on 4 sticks if you drop the speed a LOT, but it is generally not worth it.

There is an A64 chip that WILL run 4 sticks of DDR400 at 1T, and it is the San Diego core. This is the core that is supposed to be able to run all 4 dimms at max. If you need this feature, then this is the only CPU that will do it for you (Supposedly, since I have not seen real benchmarks of this).

san diego won't run 4 dimms at 1t either, unless they are single sided (at least mine won't)

Afaik Venice works with 4 single-sided Modules at T1 but with 4 dual-sided only at T2. But this was also possible with certain mainboards plus Winchester.

Ahh, hence the reason that I said "Supposedly"... I am loathe to really believe claims such as this until they have been confirmed in the real world and tested. Otherwise, they are just PR waiting to be verefied. Thanks Xed, you saved me the trouble of wondering if I should move up to San Diego -- I think I will stay put with my 3000+ Winchester that does 2.7 GHZ on aircooling... It works just fine for me!

Well My MSI k8t-fisr wouldn't let me use the 4 sticks at 400mhz no matter what. I was using a winchester.
