hey guys, sorry this is my first post on here, but i've been following the science of this forum for many years now.. i feel its one of the best spots for pc knowledge around. many thanks and cheers....


here is my dilema:

i have pc 2700 ram DDR @ 333mhz. 2pcs 512mb each. I just bought an asrock 775 dual-vsta for this and many other reasons. The anandtech article on this motherboard states that it is capable of running DDR 266 on the system while still using an e6300 at the 1066mhz FSB - presumably using a mem divider.

1. Will i be okay or successful at running this mobo/cpu with my DDR?

and

2. will i be able to raise the FSB to approx 300mhz for an overclock?

im hoping for approx 296mhz on the FSB for the asrock and keeping the 9x multiplier on my e4300 while still using my DDR ram.

this may be a pipe dream, but to go to ~2650mhz (290x9) when coming from my athlon xp 2000 while only spending 161$ (cpu) + 55$ (mobo) will be a nice & inexpensive treat.

Thank you,

jared

You shouldn't have any problems whatsoever with your memory. 290MHz FSB is easily attainable on that board - most hit 300MHz, but that's it. Anything beyond that is very, very rare - but since you're shooting for 290 you should be good to go.

hey thanks... i was just reading another post that had me worrying because it said that the boards supporting ddr required 400mhz pc 3200 minimum.. i sure am glad. do you think it will be possible to get 300 x X9 multiplier? 2700mhz would be nice. i cant belive i can outperform an fx 70 athlon or a p4 3.8ghz EE with a 150$ cpu!

I think you already know and understand this, but just wanted to remind you to think about your RAM ratio when using a front side bus as high as 290 with your 333MHz RAM.

Your RAM is rated at 166MHz (166 times two equals 333 for double data rate, DDR).

A front side bus of 290 is much higher than what your RAM can do which is 166. Your RAM would be running at 580MHz (290 times two) at a 1:1 ratio which it could never do.

Use a divider to keep your RAM near 166MHz and you should be fine without a RAM upgrade. You may have to use 2:1 ratio which would under clock your RAM to 145MHz (290 divided by two) instead of 166MHz, but keep you stable.
