Switching to intel port from marvel makes no change...SSD still a bit slow

OK, I know this topic has been done to death on here, and I've done my reading.
Haven't found my exact problem, so I gotta post.
I recently got a Samsung 840 series SSD, 250G.
My board is a P8P67M-PRO. I have an auxiliary HDD also in my system.
My goal was to install install windows fresh on the SSD.
I attached the SSD (to the blue 6GB Marvell port) and installed windows.
I've done everything else...optimized the drive, disabled write caching, etc.
I've also enabled AHCI mode.
Using Samsung Magic's benchmark, I get around 360 read and about 168 write.
The advertised speeds are around 515 read and around 300 write.
So, I came across using the Intel 6GB port instead of the Marvell.
I changed it to the Intell, but speeds haven't changed.
Also worth mentioning in the BIOS, I can find the option to change the Marvell controller to AHCI, but no options for the Intel port.
I REALLY don't want to reinstal windows again. Is there a way to get that Intel port working up to speed?

Thanks...I know this query is a bit redundant, but I swear I've done a lot of reading on these forums and can't quite get a handle on my exact situation.

I'll perhaps try that tonight. I'm Teamviewering from work right now so I can do anything in windows or reboot, can't do anything in the BIOS remotely, or switch cables.
Read that I have to disable the marvell controller in the BIOS in order to force it to load the Intell port AHCI drivers or something like that. Interesting....

I don't have another computer available...except my wife's Mac laptop and I somehow don't think that's an option, heh.

This is driving me crazy.

No need for fresh install... Have you done SSD optimization...Settings to speed up HDD slow down SSD.
Do the optimization to maximize the performance of SSD. Optimization will also reduce the number of I/O
Check this site. There is also optimization specific to the OS you are using...

OK, I've read through the guide you posted and I have one thought. When I installed windows fresh (last week) I installed to my new SSD attached to the 6G Marvell port. Then I attached a secondary HDD for storage. THEN, I read that the Marvell port was a bad idea, so I switched the SSD to one of the 6G intel ports.
I'm hoping that switching to a different port is OK after install, and that the speed of the new port can be utilized without installing windows fresh, again....

Dear Tom's Hardware

I'm an idiot.

followed the cables with my eyes, and yet I managed to allow my HDD into a 6GB/s and my SDD into a 3GB/s.

switched, used Intel rapid storage technology, and getting around 505MB/s read times, which is about advertised speeds.

Again, deepest apologies to anyone who wasted time on this.
