Even though you have 8 threads, Win only recognizes the 4 cores (at least for the folding clients), in order to do hugeadv WUs (6903/04), you have to have 12 "cores" recognized by the folding client. In Ubuntu you can trick the OS into telling the client that you have more cores than you actually have, thereby allowing you to work bigadv and hugeadve WUs.

I run them through a VM, I've also run them native Ubuntu, and my PPD was about 3-4K PPD different, but if I use the VM I can still use my computer while its folding!

Because stanford develops everything for the linux client first, then ports it over to windows and osx once its stable.

Well, I don't know since I never tried hugeadvs on my vmbox, but regular smp went down 50 seconds per tpf(2:10), using vmbox. Don't know why it would be any different for a hugeadv or bigadv. Just my experience and two cents, I guess.

Your correct. It will increase your PPD. Though it will be less then if you were to run linux natively.

Limited? Cause you can't play games or what? And you probably mean Linux since Ubuntu is a Linux distro and Linux is what's needed.

Nope, Linux FAH client only. No matter how many cores you've got in Windows... (not talking about VM here, native Win client).

If the Windows FAH client only detects 4 cores the i7 wouldn't get bigadv WU, which they do. So the system reports 8 cores (or threads or what you wanna call 'em) and that's what the client is seeing and reporting to the AS.

He's probably referring to Linux in VM vs native Linux. The latter would yield more PPD, but how close they are depends on few things.

I was under the impression that you had to have 12 cores (or at least reporting 12 cores/threads) to fold hugeadv (6903/04) WUs? This is why even 2600ks have to run in Linux to do hugeadv? I also was not aware that you could fold bigadv (non-6903/04) WUs in Win client? Possibly with a i7 990x, but not with a 2600k, or am I wrong about that? I only have a 2500k, so I don't have first hand knowledge of what a 2600k will do, but I hope to find out soon!!

You cant fold hugeadv in windows with any processor. Period. The logic is only build into the linux core. I tested by transferring a 6903 from nix to windows and it would err out because it didnt recognize the core needed for the WU. Linux is the only way to fold 6903/4 right now.
