    EDIT: Solution to slow WinRAR extractions below!

    OK so on my motherboard I pretty much need to leave EIST on if I want to overclock. This isn't something I mind as power and heat saving are good things. However I'm wondering why it hardly ever gets bumped up unless I run something REALLY intensive? I can watch a 720P video and extract a RAR at the same time and I'll only see it go above 6x to 7 or 8 when I'm switching around between windows. Is the system smart enough to push only as fast as it has to in order achieve the required computations? Basically I'm wondering why I'm sitting here watching this RAR take so long to extract, does the system know that the bottleneck is the hard drive and it can't extract any faster so it doesn't boost the CPU while doing this?

    the RAR is bottlenecked by your hard drive.

    RAR's extract to a temp folder on your C: drive, before getting moved to where they're going, heres an example.

    RAR itself is on C: drive, opening somewhere else on the C: drive (or another partition of the same physical drive)

    Open RAR, copy from C: to C: (rar temp), then move to destination C: - its literally copying the file(s) three times, hence the awesome slowness of RAR's on most systems.

    I can watch 1080P movies on a 2.1GHz athlon64, so yeah, its a safe bet to assume your CPU can handle 720P at low Ghz ;)

    Thanks for the quick response. And WOW, I did not know that about RAR... how awesomely efficient!

    i saw someone use a keyboard shortcut once to extract the rar directly to where it had to go and bypass the C: temp part, but i have no idea how the hell he did it, so i cant tell you how either.

    This is for you then. I found out how to not have WinRAR copy to a temp folder. Well, not really, it's always gonna make temp files, BUT, you can leave the temp folder field empty in the options and it will use the folder it is working in to make the temp files. This is good for those of you who extract the data directly into the folder or a subfolder where the RARs are. I did this and noticed that it's kinda like putting a performance camshaft in a car, the RPMs are steady and the power band (extraction rate) is flat because you're working in just that one section/platter of the drive instead of having things copied over to your C drive.

    Cheers.
