E8400 multiplier stuck at 6

hello all,
i recently purchased an e8400 to install in an old build to hopefully add some speed. well, the multiplier is stuck at 6 so it won't go above 2Ghz, even when using prime95 to get it to step up.
Things i have tried:
i cleared the cmos after installing, all i changed in the bios after that was turning AHCI like it was before. then figured out it wasn't going full throttle.
i set windows power management to high performance.
i went in to the very basic bios and, using google, disabled everything i could relating to power management.

the motherboard is an ECS GF7100PVT-M3. my roommate has a slightly newer build with and e8400 that i could borrow, if i asked real nice, to see if i got a dud cpu. but before i do all that work i hoped i could get some help from this great community.

has anyone else ever been able to resolve this?

thanks in advance,
RegGuy290

What version of BIOS are you running? Also is Intel Virtualization Technolgy enabled in the BIOS.

i just disabled virtualization and it still is stuck at 6. is there a list of everything i should disable?

i tried updating the bios but AFUWIN won't work with win7 64-bit. and i don't know how to use AFUDOS. and the bios update i think only adds support for e8600. e8400 is on the list for compatible processors from the first stock bios.

better in a dos environment anyway. always get nervous doing updates in the GUI, never actually had an issue thou.

all i got to work with is win7 64bit. no true dos environment. it can't believe theres no way to do it from the bios itself.

turns out i don't have REAL ami bios. no ami bios version numbers on the POST screen and no printed ami logo on the board. so their utilities won't work even if i could from a 64bit environment. sad day. at least newegg carries a few more 775 boards now if i get real desperate for the speed. right now it is faster than the e4600 that i pulled out so that's not bad.
