Older motherboard, an MSI K7T266Pro2-RU with Athlon 1600+. Onboard Promise Raid controller. I'm putting on two WD 120gb 8mb ATA100 drives in Raid-0. I've never overclocked this board and it doesn't have a PCI lock. I'm concerned about raising FSB and blowing up the raid, which would be bad since it's Raid-0.

The FSB is at 133. Is it safe to move it up or should I just jump the multiplier and be happy with that? Funny, it wouldn't have been such a worry before boards had PCI locks but now I'm concerned.
 
AFAIK, you were running the same risk overclocking without having your HDDs in a RAID setup. The PCI bus is overclocked, which can potentially lead to storage problems. I run my HDDs out of spec on my dually @ 150 FSB and I've never had a problem (these are WD800JBs), but if you're conerned, don't overclock as high.
 
I figured that the Raid controller might be more sensitive since it's also running faster and has to juggle between two drive controllers. But I know squat about how the internals of Raid-0 actually work so maybe it is less likely to crap out at higher FSBs.
 
The chips implimented on the motherboards are the same ones implimented on the pci cards, so i believe it is safe to say that the same variance should be ok, 38mhz with, check ur divider options and see what you can do. i personally ran an Abit KX7 with the highpoint controller in raid 0 at 181 FSB and hard drive corruption was never an issue. I believe that was at 1/3/5. As far as the southbridge goes, the kt266 is pretty solid, I had a KR7a Raid before the KX7, i believe it had a highpoint as well, but my 8k3a had a promise one and i ran that up to 173 I believe, hehehehe. Point being, try and settle for 166FSB and than pick on ur multiplyer, CPU speed enhances performance much more then bandwidth anyways.
 
I belive(and could be wrong) that promise has an onboard clockgen, so although you may have problems with the card and array, your drives should be fine.
 
OCing means risks will occur. If you are OCing and something starts acting strange, back the OC off and find out why its doing it. Most hard drives can take some OCing without a problem. Just listen for strange noises, data corruption or things like that and you should be fine. If you have important data on it, I would back it up before you do anything, just to be safe.
