Overclocking is causing extra disk access. Why?

post #1 of 5
Thread Starter 
Something strange I've noticed since I upgraded from 6 Gig of RAM to 12 Gig's of RAM. When I try and max out my overclock ~4.35 GHz the hard drive thrashes a lot more than when it's not overclocked. It's substantial and since it's on a classic Seagate SATA drive it's loud. Anyone know why this is... and if there's some BIOS options I can change to help alleviate it?

Thanks!

Not to state the obvious, but have you done hard drive tests?

In addition, you should actually be using your hard drive LESS with more memory.

With all that extra speed, your CPU is getting bored. It's just playing checkers with your files. <insert hard drive thrashing noise here> King me!

On-Topic - That is pretty odd... Have you ran any HDD tests as Ryan suggested? What processes are running in the background? Is Indexing on (with iTunes, Indexing will thrash a HDD until the cows come home), what's your pagefile set at?

All things I've done, and yes it is terribly bizarre. Here's more detail:

* Win 7x64 is on SSD Drive and IE is on Seagate drive.
* Swap file is set to a spcific size of 3072 and that is on my C Drive (the SSD with the windows install).
* Seagate 7200 rpm (500 Gig) is for backup data and that's where I have temporary internet files so my SSD isn't thrashed.
* Seagate speeds and health are fine.

Now there is one other I just thought of that really should do it... When I was trying some different OC chemes out I installed the Intel inf and Intel Matrix Storage Drivers. That couldn't cause it, could it? Technically the latest INtel stuff should be better than default Win7 drivers?

There is one other thing. The last BIOS update added:
"ACPI 2.0 mode" - disabled

I use Win7x64 so I enabled it though I don't use and power mangement. Could this be a cause? I think I'd have to re-install to go back on it.
