KT7RAID only supports UDMA33 with the onboard IDE ports?

[Jugernot]

I was looking at getting the KT7RAID and noticed that it only support UDMA33 with the onboard IDE ports (Non High Point ports)? I thought they supported up to 66?

I have a Western Digital Expert 7200rpm UDMA66 18gig and Seagate Barracuda ATA 7200 UDMA66 20gig. How much faster will they run on the highpoint controller UDMA66 versus the KT133 UDMA66?

Thanks

btw: If I have an existing hard drive with Win2k on it and I put it on the Highpoint controller, what do I have to install to get it automatically boot without getting a "No operating system found" error message?

Where did you get this info. The Southbridge of the KT133 chipset supports ATA66.

Kt133 natively supports udam33/ata66 - Maybe you misread - older slower devices udma devices should be placed on the primary/secondary ide controllers and not the tertiary/quarternary Raid ports

If you have only one hard drive, I would put it on the Non Raid IDE ports and disable those extra ports (hpt370) in the bios to have a faster boot up time. I believe you will only see performance gains if running RAID - striped HD's or if the HD supports ATA100

Nope I didn't misread it. Read about 3/4 of the way down:

I current have two hard drives, a dvdrom, and a cdr. I was planning on each having its own channel, for optimal throughput. The two hard drives on the Highpoint controller and the other drives running on the KT133 chipset channels.

btw: I was asking about the "No operating system found" error because my brother has a Gigabyte board with a Highpoint controller onboard and he had to go through a special procedure when he formatted and reinstalled Win98. What do I need to install to get it to work with an existing hard drive with OS?

Well, technically it should state ATA 33/66. However, I've found that a IBM 75GXP 30GB drive attached to the onboard IDE port of my KT7 (non-RAID) when benched with HDTach 2.61 has a burst speed of 38.6MB/sec consistently. When the 75GXP is attached to a Promise Ultra100 controller in the KT7, the burst rate is off the scale. Maybe they're being honest about practical throughput ?

Juggernot,
I never noticed that at the abit website until you pointed that out.
Anyways - The Kt7-KT&-Raid manual lists under Multi IO finctions
tWO cANNELS OF bUS maSTER ide poRTS sUPPORTING UP TO 4 udma 33/66 DEVICES
tWO cANNELS OF bUS maSTER ide poRTS sUPPORTING UP TO 4 udma ATA-100 DEVICES (raid only)

As far as NO OS error- I have always done fresh installs on my KT7-Raid and Bp-6 so Im not sure but MAke sure you have latest Bios for MB/HPT or install the HD w/OS on the non Hpt ide ports, install the drivers for the Hpt controller, then move the HD over to the Hpt based IDE ports - making sure you set in the MB bios the correct boot sequence for each respective ide port.

When you say &quot;raid only&quot; do you mean a single drive can't be used on each channel seperately? I was under the impression that a raid controller can be used either way, no? I wasn't planning on utilizing the raid feature until I get two identical drives.

No, he ment on the raid version of the board, has nothing to do with RAID itself.

Does anyone know of a thread, web page, or have their own testing comparing a RAID setup vs a Non-RAID setup of identical hardware? I am getting tired of instability of my KT7-RAID (which I am using two IBM 75GXP 15GB drives) on the RAID controller and am considering running without RAID. ANyone have comparisons?

BTW noticed Anand made same(ata33 only) mistake in his KT7 review...

Stuman,
Check out some of JonnyGuru's posts in this forum. Highpoint RAID performance is piss poor.

Yeah, hell, I can only get a little over 44,000 in Sandra....
