sys: AMD 2000+, Abit KRA7-133r with onboard highpoint 133-RAID, Creative Audergy, 2x Seagate Barracuda V 80GB, 1056MB DDR ram pc2100 (266mhz), winXP etc I recently bought two Seagate Barracuda V 80GB and used the onboard RAID function highpoint hpt372 with the lastest bios available from ABIT (hpt-driver 2.32 I think) to make a stripe (raid-0). I installed windows and a bunch of programs. Anyways when I watched movies, played music, games etc I noticed clicking sound from the speaker whenever the harddrive was working. I suspect the power spikes from the two drives working at once causes spikes in the soundcard. After reinstalling windows without raid the problem disapeared. my question is this: does the problem lie in (a) The Powersuply, a chieftech 340W that came with the case, a Chieftech Dragon (b) The motherboard. I heard 2-phase power on the mboard sucks and new ones use 3phase or even 4phase in some places. (c) The RAID-chip. Does highpoint suck or not? Thankful for comments. /Mikael PS. tested the speed of the disks with and without raid in Nero. With RAID the transferrate was 35-46MB/s. without RAID it was 35. Doesnt seem worth the trouble in retrospect. Nice to be able to have additional 4 ide drives though ;) PS2. sorry about misspellings & dataerrors, I´m too tired to correct myself
