NO! Pardon my shout, but PCIX ain't PCIE!! PCI-X is PCI Extended, is aimed at servers, and is effectively an extension of PCI, only wider (64-bit) and a factor faster than PCI's 33MHz (66 or 133MHz, for instance). Sockets are usually white, like PCI's, but longer. PCI-E or PCI Express is more recent, sockets are typically black, and size depends on the number of lanes potentially available, eg x1, x4, x16. Though sometimes a larger socket has fewer lanes functional. PCI, PCI-X and PCI-E are mutually incompatible plug-and-socket-wise, so cannot be mixed up, even intentionally. Here's a motherboard with all three: http://www.supermicro.com/products/motherboard/Xeon3000/3210/X7SBA.cfm 'Express' is not 'Extended', and though both names begin with 'ex', one is 'E' and the other is 'X'. Do not confuse!

The new connectors with 1,4,8 or 16 "serial" data paths to the card. My RAID card uses a PCIE with 8x channels. Everyone was saying that you have to be careful what motherboard, it has to be "compatible" etc. I have used it in two different MBs, neither of which was on their "compatible" list. John W.

And last year I was going to buy a card to hook up SATA drives on one MB that doesnt have SATA connectors. Had to search PCI card - most cards are PCIE, which this MB doesnt have. Each time I turn around, I find I cannot upgrade or replace this or that, but that's the trick in PC business: You have to buy a new Computer every 3 to 4 years. Lembit BTW, what's PCIX? is it 'extended'? I know extended as PCIE. ----- Original Message ----- From: "jwcolby" <jwcolby at colbyconsulting.com> To: "'Discussion of Hardware and Software issues'" <dba-tech at databaseadvisors.com> Sent: Monday, January 28, 2008 7:38 PM Subject: Re: [dba-Tech] Performance in disc partitions > ROTFL.
