Is Ultra ATA/133 supported on intel 810e motherboard. I bought my PC in June 2001. It is a Compaq Presario 5000 series PC. I don't know how to find its model number.The device manager shows a 810e graphics controller. I wanted to upgrade with a Maxtor 80GB Ultra ATA/133 7200 rpm harddrive.That is when this problem came up.
No. The ICH southbridge only supports ATA100. However, you will not notice any increase in speed with a drive on ATA100 that can do ATA133. The spindle speed is going to be the biggest difference. ATA133 is really a marketing gimmick mostly. That's the maximum burst transfer speed, not the sustained transfer speed, which is somewhere around 40MB/s last I checked. If you were getting a hard drive that was larger than 137GB, I'd be concerned (this is due to a hardware limitation but can be bypassed with an add-in controller card), but since it's not, you shouldn't face any compatibility issues. You should be able to configure the jumpers as necessary and put it in.
Ultra ATA/133 Thank you Big B for you prompt reply. Anyway what is this Ultra ATA/133 ? Which all intel motherboards support this?
It offers a theoritical bandwidth of 133mb/s of transfer, but like Big B said, it's only in theory. The actual speed is nowhere near that.
Last I checked, Intel has yet to release any version of ICH (including the ICH5/R with the i865/i875 chipsets) that support past ATA100. Chipsets from Via, SiS, and nVidia (nvidia doesn't have anything for Intel, unless you count the X-Box) do support ATA133, but I'm not sure if they've got anything for the Socket 370 platform.
