Fsb:dram ?

[vaus]

specs:

e7300

msi p7n platinum

ocz ddr2 800mhz

 

I have my FSB at 350mhz(rated1400) with 10x multiplier, 3.5ghz cpu, and my RAM at 800mhz; FSB:DRAM = 7:8

I thought I needed to keep my rated FSB ≥ 800mhz to get the full use from my RAM, but a friend said I need to keep my FSB at 400+ to get the full use of my RAM.

Is this true?

Would it be better if i raised my FSB and lowered my multiplier?

 

FSB 400mhz (rated 1600) multiplier 8.5x or 9x would be 1:1

What kind of FSB limit should I expect to see with the 750i chipset?

Best performance is a low multiplier with a high fsb, but most chips don't like that. If you get your ram 1:1 with your fsb, then you should be fine. You won't really notice a huge performance boost though.

The main thing is to have a stable system. If your ram can take it push on the FSB to attain faster ram speeds. This, however, might require extra voltages to have your ram stable if you decide to push above 800.

Good Luck.

my computer won't boot at 400mhz x 8 using the same vcore that made it stable at 3.5ghz, not even to the bios ̚̚>.>

 

so if i have my FSB at 350mhz will i be losing out on some of my RAMs performance?

What Vcore are you using at 400X8?

What Vcore are you using at 400X8?

 

I can't see it in my bios cause it onlt shows how far from stock volatge I am, but it's 1.248 idle in os.

i think u can see ur cpu voltage by looking in the pc health in the bios......

Did you remember to change your RAM divider?

I don't have that in my bios

I have a strange bios, I can't set the fsb:ram ratio. I just choose the rated fsb speed and ram speed.

 

The main reason I made this thread was to find out if I need my fsb to be at 400+ to get the full potential from my ram. Do I?

Yes and no. If you have a ram multiplier of 2, then yes, your 800MHz ram will only run at 700MHz. However, that loss of performance is on the order of 1x10^-6 seconds. The whole issue of the need to run your memory at the same speed as your FSB is debatable, but in real world applications (gaming, editing, virus scanning, whatever) theres really no evidence to say that a 1:1 ratio matters more than the pure speed of the components. I mean.. there cant be. In order to get anything else, you have to change the speeds, so its impossible to really know past what people think should happen. So do not worry about getting a proper ratio, instead worry about getting your CPU to run as fast as you can, thats where any and all noticable difference in performance will be found.
