Indeed, but it's still the best for athlons. The biggest difference is the 512 MB/sec PCI bus instead of a 256 MB/sec. They are also cheaper often available without on board video like most of the MP chipset boards. via, ali and sis haven't come up with anything newer? that's kind of hard to believe! None of those companies got into the dual athlon market, they all came out with numerous uniprocessor chipsets. This is changing with opteron, at least nvidia plans to come out with a SMP chipset. i'd like to run dual MP 2800's with barton core. udma 133 or higher. built-in usb2.0 would be nice (although i understand that usb2 cards are dirt cheap). There were usb2 bugs in the earlier MPX boards, most vendors threw in a free pci card for usb-2.0. I believe this was fixed. IMO I wouldn't invest a whole lot on such systems. They tend to be rather heat sensitive, definitely plan on keeping the environment cool, and having lots of fans. Performance is often limited by the shared memory bus. any mobo recommendations? I have 24 tyan MP boards, and 8 MPX boards and they all work quite well. Keep in mind opteron-240s are $190, and the opteron dual motherboards start at $240 ish. The opterons feature (compared to the MP's) Much better perf per watt Double the registers (int, fp, and vector) SSE2 (athlon doesn't have it) Double the register size (larger pointers and ints) On board memory controller (lower latency) Per CPU memory interface (not shared) Dramatically better performance per MHz. Less total power. Few extra security features PCI-X (1GB/sec) Often sata is included in the motherboards. -- Bill Broadley Information Architect Computational Science and Engineering UC Davis ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

Dan hi dan, thanks for the info. that's too bad -- asus has always put out good stuff. it destroyed two IDE drives?!? how did it do that? i've been thinking of the tyan S2466-4M, which seems to be popular with the athlon MP crowd.

Hmm, has it been that long? :-) Yeah I think that's all there is. I know Asus and Tyan have such boards, but their USB is only 1.1 in both cases. Tyan also has some new dual AMD Opteron boards; 64-bit is where all the AMD interest seems to be now. -- Rod http://www.sunsetsystems.com/ ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
