I have an ASUS A8N-SLI Premium mobo running XP. Adding in a Highpoint RocketRAID 454 RAID card is killing my system. Benchmark performance results show that my system (CPU and video) have been reduced to 20% of the original performance. I can yank the card out and my performance goes back to where it was.
Now, I know all about using the system CPU performance by using this RAID card, but that really isn't the issue since no processing or disk read/write is going on. It is an idle system, just running benchmark utils.
I started with a fresh system, new XP, etc. I have all of the correct drivers and BIOS as per Highpoint. I have poken with Highpoint, and they are stumped. Do any of you experts have an idea or what else to examine?
