UDMA133 on a 5 year old PC?
Hiya,
Just purchased a Maxtor 6Y080L0 drive (80gb 7200rpm UDMA133). Have installed it into a (circa 1999/2000) Dell Precision Workstation 410MT, using a 40 pin / 80 connector cable. It works, but only comes up at UDMA33... ("kernel: hda: 160086528 sectors (81964 MB) w/2048KiB Cache, CHS=65535/16/63, UDMA(33)") Is it theoretically possible that this PC will support faster than UDMA33? I've read the user manual for the PC (http://support.dell.com/support/edoc...t/23205a00.pdf & http://support.dell.com/support/edoc...t/0655cbk7.pdf -- snipet pasted below), but I can't see any mention of UDMA. Is it worth pursuing or is UDMA133 only supported by recent motherboards? Thanks! TC --------------------------------------------- Bus types: PCI, ISA, and AGP Bus speed: PCI: 33.3 MHz ISA: 8.33 MHz AGP: 66.6 MHz (2X-capable) Internally accessible: EIDE drive: two 40-pin connectors on PCI local bus Primary SCSI channel: one 68-pin Ultra2/Wide SCSI connector Secondary SCSI channel: one internal 50-pin Narrow SCSI connector The enhanced dual-interface EIDE subsystem supports two EIDE interfaces (primary and secondary), each of which can support up to two EIDE devices. The EIDE controller resides on the high-speed PCI bus. The primary EIDE interface (IDE1) supports up to two high-performance EIDE devices. The computer's boot drive should be connected to the primary EIDE interface. The secondary EIDE interface (IDE2) also supports up to two high performance EIDE devices, typically EIDE tape drives or CD-ROM drives. |

440BX chipset can support UDMA mode 2 which is ATA66 but I'm not sure if it
was implemented on this motherboard. At least WinXP reports UDMA mode 2. "Tony" wrote in message om... Hiya, Just purchased a Maxtor 6Y080L0 drive (80gb 7200rpm UDMA133).

Yes, you are right. No ATA66 with Precision 410 motherboard IDE. It also has
only one IDE channel. Sorry, I misunderstood the following statement: "In addition, the 440BX AGPset can interface with ATA/66 HDD in UDMA mode 2" from: http://www.intel.com/design/chipsets/440bx/ "Egil Solberg" wrote in message ...

My Dimension XPS-R450 (circa Jan '99) runs UDMA133 fine - with a SIIG PCI Ultra ATA controller card. Check it out at http://siig.com/product.asp?pid=437. About 14 months ago the lowest price that I could find with a Google search was about $35 or $40 from Dell online sales. I use "round" IDE cables with aluminum braid shields for my two Maxtor 6Y060P0 HDs (DiamondMax Plus 9s), and the cables seem to work fine - maybe because they're shorter than the standard ribbon cables. *TimDaniels* |

Since the motherboard isn't equiped to handle such fast data rates,
does it actually make sense to add a modern IDE controller card? Will it result in faster disks/higher throughput, or will it just move the bottleneck to a different place? (Thanks for the help so far everyone!) |

Will it result in faster disks/higher throughput, or will it just move the bottleneck to a different place? Seek time should not better with this new controller, but it will allow for more disk throughput. |

If your PC can handle PCI, it can handle ATA/133 through PCI. Just put in a new controller card. You'll love it. BTW, the SIIG controller has FIFO buffers twice the size of the Promise controller's, and the Diamondmax Plus 9s model nos. ending with "P0" have 8MB caches, while the ones ending with "L0" have 2MB caches. These, of course, are insignificant unless you're in love with numbers. :-) With a 5-yr old machine, you might as well base your choices on price. *TimDaniels* |
