Raid array and overclocking

Mint_Sauce · 7 Nov 2007 at 11:41

I want to overclock my rig but I wasn't sure how raid would react compared to a single disk. As I'm new to Raid I just wanted to check to make sure there's nothing I have to be careful of just in case I lost all my data!

I'm still running Raid 0, going to order another drive for Raid 5 soon - should I wait till then or is it not going to really matter?

The RAID array shouldn't react any differently to a single disk when overclocking although be careful if you start getting close to the limit and the PC starts crashing on you. RAID0 can give you problems if the PC crashes in the middle of a disk operation.

Ok, thanks - think i'll order up another drive today and then overclock when it's Raid 5 or maybe use the new drive to install XP and testing tools then when it's stable format it, re-plug in all the drives and change to Raid 5.

I've been running RAID 0 for about 15 months and never had an issue with overclocking. Think it depends on if the drives that are used are any good or not.

Well it would also depend on whether the controller the drives are connected to are on a bus that's also being overclocked or whether the controller clock is being kept static. If the controller's bus clock is being overclocked as well, then the controller chipset is therefore also being overclocked and it thus becomes possible for it to start making mistakes during transfers etc., which may cause data corruption issues (whether RAID'ed or not.) On motherboards where the PCE/PCI-E bus clocks are seperate from the FSB/system bus clocks, and the controller is on one of these static clock rate buses, overclocking the rest of the system would then obviously not be a concern, but on systems where the PCI/PCI-e bus is linked to the basic FSB clock rate and/or where the controller is in any event effect also overclocked (e.g. when integrated on the NorthBridge), you would have to keep an eye on the controller integrity as well. Hope that makes sense.

I see what you're saying, any idea if it's linked on the IP35 PRO mobo?

I think you might have to make sure that PCI-E is locked to 100mhz in the bios, there may be an option saying something like "PCI-E locks" that you need to look out for, I can't tell you exactly since I don't have that motherboard but on my Asus it is named something like that (doesn't work but that is another story anyway).
