Hi I have a PQ5 PRO asus mobo with 4gb of
OCZ... I have a quick question the BIOS
detects my E6600 cpu at 266*6 which i would
have to downclock my ram for to run at 1:1. I
was wondering what is the difference between
400*6 = 2.4ghz and 266*9=2.4ghz. But the
first one would enable me to run my ram at
800 at 1:1. am I overclocking it massivily if
i adjust the FSB that way? I keep getting
random crashes and my bios reverts to
defaults on start up :(HELP -- I just built this and have been out
of the computer loop for a bit
On Intel systems, the faster you can run the FSB, the better the performance. It's good to see you understand about running 1:1, that will save a lot of explaining.
The reason your CPU is running at 6 x 266MHz is most likely because you have SpeedStep enabled. Go into the BIOS, find SpeedStep & disable it. Set AI Overclocking to Manual, then change your CPU clock settings to 6 x 400MHz & do what you gotta do to get the RAM to run at 400MHz (DDR2-800). Also lock the PCIe at 100MHz & disable any/all Spread Spectrum settings.

Right on so just to be clear 400*6 and 233*9
are the exact same thing in terms of heat? Im
not seriously overclocking it by doing this?
Also about the ram since I have a 2x2gb in it
now. if I made it 233*9 and added two more
sticks dual channel of 2*1gb to equal 6gb
running at 667 would that be better than just
4gb running at 800mhz?

1st of all, it's 9 x 266MHz, not 233MHz. And 2.4GHz is 2.4GHz. There *may* be some added heat due to the faster FSB setting, but it won't be significant. The motherboard chipset would be affected more than the CPU.
On an Intel system, it's best to maintain a 1:1 ratio. That means:
800MHz FSB w/DDR400
1066MHz FSB w/DDR533
1333MHz FSB w/DDR667
1600MHz FSB w/DDR800If you hvae faster RAM (which you do), simply underclock it to match the FSB. Remember that Intel quad pumps & RAM is double pumped so you need to divide the FSB by 4 to get the true frequency, divide the RAM by 2.
For example:
1066MHz FSB / 4 = 266MHz
DDR533 / 2 = 266MHz

Ok so to clarify my question furthur. Whats
better to have.9 x 266Mhz with 6GB of Ram at 533FSB
OR
6 x 400Mhz with 4GB of Ram at 800FSB

I'm not familar with Win7 so if that's what you're asking about, I don't know the requirements. But if you're running a 32-bit version of ANY OS, 4GB is the limit. In fact, only about 3GB will be available due to the way the address space is mapped.

Even if you're running a 64-bit OS, what do you do that would require 6GB RAM? Are you familiar with "the law of diminishing returns"?

I dont know if my ram maxes at any given
point its hitting 100% and that stalls new
instructions from being sent until the old
ones are delt and processed. So with this
said I keep my computer one for months at a
time. I use it as a basic server so
considering most servers have +16gb this
shouldn't be a big of a suprise. But ill take
it that you think the 4gb @ 800mhz is the
better of the two. Thanks for your help

Oh and yes I am familiar with that law, but
the solution to too many workers forming
lineups at the machines is get more machines
or build another factory...

You didn't answer about the OS?
If you're running a 32-bit OS, it doesn't matter how much RAM the board supports. 4GB is the limit, with between 3.0-3.5GB being available. Adding more won't do a thing.

i have 64 bit vista, used for internet, music, movies, modern 3D gaming, etc.
to the best of my knowledge, i have never been bottlenecked by having only 4GB of RAM.
