Hi,

The chip information is as follows:

Highpoint
HPT374
0330 T020

I have been speaking to Highpoint tech support about this and they
have confirmed that the problems I am having is a driver issue when
using RAID 5.

They are currently developing a new driver which will get around the
problem of the card using high CPU utilization and causing the sound
card and freezing problems.

Regards,
Gerlad.

One thing you might want to do is shift how your cards are placed in the
system, if that's at all possible. You may also want to check with your mobo
manual and move the Audigy to the PCI slot which does not share resources
with any other device in the system. If the problem still occurs, change the
1640 to the "lone slot" and see if that helps.

One other thing which might help is to check the BIOS of your mobo and see
if there is a PCI Delayed Transaction selection, and if so, set it to
enabled.

P.S. On an slightly different note, I have the 1540. If you get a chance,
could you write down the numbers on the big Highpoint chip on the board. I
just want to see if they changed the revision of the chip with the 1640. I
also had some of the problems you speak of, it's all together common with
Creative cards. Eventually it comes down to learning to ignore it - although
things hopefully will change for the better once the next generation of PCI
slots come out.

Hi,

I've just purchased a RocketRaid 1640 controller but have run into a
problem with my sound card.

I have 4 x 80GB SATA hard drives attached to the 1640 in a RAID 5 set.
My sound card is a Creative Sound Blaster Audigy.

Other specs:
OS: Windows XP Pro
CPU: P4 3.2GHz (800FSB)
RAM: 1GB (DDR400)
SM: ABit IC7 MAX

Sound: Creative Sound Blaster Audigy

The problem is whenever the hard drives are reading/writing data the
music playing via the sound card becomes very crackly and distorted
making it impossible to listen to.

I have installed the latest sound card drivers but this has made no
difference. The 1640 Controller driver and BIOS version is 2.0.3.0
(latest).

I've tried increasing the AGP/PCI MHz ratio, tried using the onboard
sound card instead, even tried configuring the hard drivers as ATA66
instead of ATA150. None of which made any difference

Is there anything I can do to stop the RAID controller interfering
with the sound card?

Any help will be most appreciated!

Thank you,
Gerald
