It would be really nice if they bumped up to DDR500+ without relying on OCing. A lot better than switching to DDR2 at similar speeds for performance and price IMHO.

I hope they go for it.
That would be really slick with Dual channel memory as well.

My next new rig will be a FX53 with 1000mhz bus. Most likely watercooled. I can't wait for it. Hopefully a really great solid nforce3 type board. I don't like the sounds of DDR2 and if AMD will refuse to use it till it becomes good enough for them, then i will back them with my purchase.

Opteron adoption of newer memory devices will be slower... but Xeon adoption of faster front side bus is no diffrent in that respect.

Its a nice architectural pay-off that AMD can increse Hypertransport speeds and improve its coherency protocol with no change to the boards... there is no complimentry logic on the board connecting the processors to each other.

Xeon opteron wait for DDR-2 they are stuck with PC2100 for a very long time.DDR-2 400 will be good there.So i expect opteron to have DDR-2 support in 2004.The faster HTT link on desktop wont give much if anything.On 2 way and bigger it will and should give a good 5 to 12 % increase in performance

i need to change useur name.<P ID="edit"><FONT SIZE=-1><EM>Edited by juin on 03/27/04 12:37 PM.</EM></FONT></P>

actually the opteron 246 and 248 support pc3200. i doubt youll see ddr2 there before the desktop version. If amd doenst think its needed in desktops, it wont be needed in servers for just as long.

i dont know why you think ddr2 will be adopted in opterons before ddr pc3200 is. i dont see advatanges to ddr2 at this point for servers over the ddr solutions today. Amd seems to agree with that. And maybe you cant find one form newsys, but you surely can find them with pc3200, for example tyan does in thier rack solutions. ddr2 may on paper have advantages but at ddr2 400, there is no reason to use it over pc3200 ddr1.

Opteron allready support DDR400.Reg buffered ECC stick that can get to 2 gig at 200 mghz does not happen often if never.Opteron itself decrease the speed of ram if there over 4 dimm use to 133mghz.If they want to go out of the DP DDR-2 will be useful.

i need to change useur name.

Thats true, although you can find 1gb pc3200 sticks taht are registered/ecc capable. i guess what your saying is wiht ddr2 it might be easier to scale clocking above pc3200. i just dont see the great need for it on the opteron and i think amd can afford to wait for faster ddr2 or ddr3. remember, opterons arent as starved for bandwidth in the fsb like xeons are in mp set ups.

1GB that not a big stick there some 4GB of Pc2100.Opteron need to take about 4GB of ram per cpu.Many 4 way come with 64GB of ram so the speed drop to 4.2GB/S per cpu lantency increase from HTT link.Have 33% less bandwith twice the latency.Add cluster interconnect lantency.

Fell refreshing

well the max any baord i have seen can support is 32gbs of ram for a dual baord, which, for the tyan baord, is 8gb per cpu. Now oyu can get some 2gb pc3200 but frankly, 16gb is plenty for most applications. really, if oyu need 64gbs of ram, you might as well go for quad opterons, or cluster dual systems. As far as ddr2 goes, I think its a safe bet you wont see ddr2 ram on opterons for at least a year untill ddr2 667 or ddr2 800 is out and at a reasonable price. I know oyu may not htink price means much , but in the places these types of htings iwll be used, i bet you they wont adopt ddr2 even if its supported if it commands double or triple the cost of ddr1 while not showing any huge performance advantages. You wont see anyhting big until ddr2 leaves ddr1 behind and they arent matched in speed.
