66MHz 64bits 2 slots system is very common design. Nothing special. 66MHz 4 slots will be difficult. -----Original Message----- From: James Tidman [mailto:jtidman@xxxxxxxxxxxxxx] Sent: Friday, August 31, 2001 7:11 AM To: SI Subject: [SI-LIST] Re: PCI at 66 Mhz Dell sells many machines with two 66 mhz, 64 bit slots........... -----Original Message----- From: david_instone@xxxxxxxxxxxxxx [mailto:david_instone@xxxxxxxxxxxxxx] Sent: Friday, August 31, 2001 3:14 AM To: SI Subject: [SI-LIST] Re: PCI at 66 Mhz This is somewhat of the original topic, but if I have a PCI ultra160 SCSI adapter card and plug it into a 33MHz 32 bit PCI bus I think the max throughput would be 4 * 33 = 132 MBytes per sec, so I'm never going to be able to get 160 MB/s continuous out of the drive. It would appear that I would need to use a 66MHz PCI bus to achieve this, which limits me to only one other card in the PC.
