hi folks.
got this:
http://valid.x86-secret.com/show_oc.php?id=319846
my rams show here as
PC2-6400 (800 MHz)
(could it be, that it shows the RAM data wrong???)
but are actually
2 x KINGSTON HYPERX 1GB 1066MHz DDR2 Non-ECC CL5 (5-5-5-15) DIMM KHX8500D2/1G

have I been fooled by the RAM dealer?? or do i need to update the bios of the mobo, so it can see 1066 instead of 800 MHz?? (I remember reading something like that, but couldn't find it afterwards...)

please help!!! I'm on the brinck of getting into a fight with the dealer..!!


 


PC28500 1066Mhz. is PC6400 guaranteed by the Mfg. to run at PC8500 1066 MHz. speeds. Simple enough. You will have to enter BIOS and set the memory voltage, timings and speed to achieve Kingston's PC8500 guaranteed rating. The default settings BIOS picks up won't get you to PC8500 speeds, the default is PC6400. The dealer is right. You must manually set up the RAM to run PC8500 1066 MHz.

do I need to upgrade the biod itself?? or will setting the ram alone do??
actually, I tries to select the 1066 MHz from the bios, and it didn't boot, then I selected the "crazy" overclock of the asus maximus formula, and got 3,5 instead of the 2,4 GHz cpu speed. but in this option there is no option to upgrade the ram.

how could I upgrade to "crazy" overclock AND set rams to 1066?? (is this possible?? recommendable?? which would be better for games, which for normal works)
 
In BIOS, you will have to find the entry points to set up your RAM voltage, timings and Speed in order for the DIMMs to perform at PC28500 speeds.

Set the following values. Forget about that 'crazy' mode stuff. Do these settings manually. Those presets you are talking about overvolt the bejesus out of your system.

RAM voltage = 2.0-2.1v
RAM timings = 5-5-5-15RAM speed = 1066 Mhz.


I don't know if this will help, but scroll down the page and look at the screen shots showing how to set the BIOS.
