Dual K-6 II mb?

[RobRich]

I know the K-6 3D family of processors support multiple CPU setups, but did anyone ever build a dual Super7 motherboard?

It would be nice, but I don't think so....
Anyone??

Only the old HX chipsets.
New ones...time, I guess

Humm... I thought AMD said no SMP support for the K6-2. If it does, though, you may want to try this. Get a dual CPU socket 7 board, and get 2 of the powerleap thingies (found on pricewatch) that change the multiplier and voltage. You may need to get a bios upgrade of some sort too. Good luck

I've seen the same AMD press report that claims K6-2 can not support SMP, but I also saw the early technical specs on the K6-2 CPU core when it first came out. According to them, the K6-2 could supprt SMP, but no m/b has been produced to use this feature. It looks like I'm going to actually have to d/l the whole PDF tech file and resolve this.

I finnaly researched this topic. Both AMD and Cyrix offer SMP through the OpenPic SMP standard. Intel uses the APIC standard, which includes code on both the cpu and the chipset. OpenPic is completely chipset dependent, the cpu doesn't really matter. I currently can't find any Super7 SMP m/b's, but Jeff might have the right idea with the powerleap socket conversion kits. My first attempt will probably be a dual 686 M-II system, due to the cheap price of Cyrix cpu's. My next hurdle is to find a m/b which supports the OpenPic standard.

Via the search function, I found the term "APIC" in this thread. What does that stand for and what is an "APIC module". The specs for my Elpina M-720 requires one for dual processor operation. Where can I get one besides the manufacturer? (See also discussion elsewhere about this board.)

Sorry to interupt.

[RobRich]

Bazango, APIC is an Intel standard for multiple cpu setups. It is additional code added by chipset manufacturers that takes advantage of symetrical multi-processing. APIC is INTEL ONLY. Intel inserts part of the code with the cpu instruction set, and part is liscenced out to chipset companies. A far as an APIC module, that means that your chipset is not built with APIC already installed, it must be executed by an additional chip. This module should be avaible from your m/b manufacturer, as this seems to be the only way I know of to get them. Hope this helps a little!
