1200MHz RAM cannot do 1200MHz?

Hi

I have tried everything from mega voltage tweaks, super lax latency tweaks and various straps to get my 1200MHz RAM to run at 1200MHz but the computer always gives the same boot error = continuous beeps = power failure???

My RAM is OCZ DDR2 PC2-9600 Flex EX 4GB Series http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_9600_flex_ex_4gb_series

Can someone hint at why the computer will NOT boot with the RAM at 1200MHZ.

I have set everything as suggested by the RAM including voltage @ 2.2V ??? Help please

Motherboard = Gigabyte P45-Extreme
PSU = Coolermaster 850W
CPU = Q6600 @ 3.6GHz (400*9)

The reason I want 1200 is because I am currently running 400MHZ FSB so 1200 should be the best setting (not 1066 which I can currently achieve).

I want 500FSB but that is another problem for another post another time (mobo will not even entertain booting at 500FSB:()
 
I was gonna say about the board not being able to handle it but I assume that it is similar to my board (EP45-DS3) which is rated for 1333+ RAM. :/
 
I am running the latest Gigabyte BIOS, the Mobo is rated at 1333MHz RAM like richb93 says.

I haven't tried just 1 stick yet, but that would suck if the Mobo can only run 1200MHZ ram if you only put 1 stick in. I can't remember reading that anywhere on the spec sheets for the board.

I will try 1 stick and report.... :/

I'm an ubernub when it comes to overclocking/clocking, but have you tried raising the NB voltage? Just that that controls the memory. (again apologies for my noobness :p)
 
tried with 1 stick inserted = fail (same beep error as before)

tried with 1 stick and numerous voltage tweaks = fail (same beep error as before)
 
Have you bumped the voltage to the northbridge (memory controller)?... BTW where do you get 1200 as being optimal from...

400FSB (quad pumped 1600), 64bit interface... You'll be bandwidth limited at with DDR2 @ 400mhz (Double data rate 800), 128bit! interface (dual channel). Higher bandwidth is more or less wasted at that FSB speed, and the only gains are slightly lower latency, which can be achieved with tight timing memory @ 800 anyway.

yes as stated in a couple of posts above, I tweaked the voltages.

so are you saying that there is no point to 1200MHz RAM? why even make 1200MHz DDR2 ram in that case?

wow, is it really a difficult question to answer?

(expected atleast a simple yes or no), you guys can't be bothered to even do that


how he fck do you get help here when everyone just cant be arsed to continue the thread.

bye

Wow. :eek:
 
well 1200mhz RAM is 600Mhz (double data rate) so with a 400FSB all you would need is a 2:3 divider giving you 600mhz RAM. Or is that what you are trying?
