I would like to know if anyone have tried the asus A7M266 with pulsar and logic audio.
I currently have a asus A7V with 256MB cas3 ram and a Duron 950 Mhz Processor. Ihave problems using sts4000 with logic and audio.
I wonder if upgrading to A7M266 would solve the "PCI Limit reached" problem ?

Subject: Check the Chipset

I you want to stay with AMD CPU, go for motherboard with VIA KT133A or AMD 750, 760 or 761 chipsets.
They all are much better about PCI performances.

Subject: interesting...

well, an interesting question - if the people of creamware could tell us about the importance of a fast memory interface versus the importance of a pci-bus freed of ide, usb etc., it would be easier to elect a board for pulsar.

rainer hain (dr.pc from KEYBOARDS) told me that a fast memory interface is far more important (i don´t believe that completely), but one of the people posting here has bought a board with a serverworks chipset (which has an incredible fast memory interface compared to the usual desktop chipsets) and he has still pci-overflows, even more than those people with via-boards.

the chipset used on the a7m266 has the same structure (southbridge connected as an pci-device to the northbridge) as the chipset @ a7v.
so it´s just the memory bandwidth that improves (not that much one could think... but ca. 10% more performance in 3d applications like games might be one or two reverbs more in pulsar - if it would be the memory interface...), not the pci-performance, like on the boards with intel chipsets (i810, i815, i820, i840, i850), where a new hub structure is used. the pci-controller is now placed in the southbridge (called I/O-Controller-Hub, 'ICH'), and freed from all the things formerly connected via pci.
also, the connection between GMCH (northbridge) and ICH now has double the bandwidth (266mb/s instead of the former 133mb/s), so pci overflows 'should not' occur that much...

however... my advice to you: get yourself into the technique of the various chipsets to get out what´s best for pulsar.

Mo


p.s. creamware themselves recommend boards with the i815 solano chipset from intel (but couldn´t explain why, when i questioned... strange...) - but i could understand, if you want to stay with amd, just for the better (and cheaper) processors.

Subject: 815 has ICH2 hub

which means IDE and the onboard (not expansion) USB ports NO LONGER TRAVEL THROUGH PCI BUS

which is great for pulsar!

Subject: i know. that makes no difference for pulsar.

that´s what i wrote. the difference between ICH1 and ICH2 is just u/dma100 instead of 66, and a slightly differing firmware.

the hub structure, which frees the pci-bus of usb and ide, is among both versions, ICH1 and ICH2.
(of course, the newer ICH2 is more to recommend)
