Does a bad bios flash affect memory speed???

OK....I'm reporting back to you as previously mentioned.

First to correct something on my part. The ram voltage is specified as 1.8v - 2.1v instead of what I said earlier which was 1.9v - 2.1v.

So I set my FSB = 333mhz and my memory timings at 5-5-5-15 with 1.8v and the system boots up and runs fine. My CPU multiplier is set to 9. The DRAM Frequency is set at DDR2-667mhz. Therefore I'm running at 3.0ghz and my ram at 667mhz.

But here's another question?

When I set my FSB = 375, my DRAM Frequency automatically gets set to DDR2-750mhz. Therefore I'm closing in on DDR2-800mhz. However, I have to reduce my CPU multiplier to 8 to maintain the 3.0 ghz. I'm still running at 1.8v.

Either way, there is no chance in hell to run my memory at 800mhz. The machine never boots. I've given up on that option.


So which one is a more optimal setup for me?

Option 1 is:
FSB = 333
CPU Multiplier = 9
DRAM Frequency = DDR2 - 667mhz
CPU Speed = 3.0ghz
DRAM voltage = 1.8v

Option 2 is:
FSB = 375
CPU Multiplier = 8
DRAM Frequency = DDR2 - 750mhz
CPU Speed = 3.0ghz
DRAM voltage = 1.8v


Thanks for the help again. BTW, should I up the DRAM Voltage even though I'm able to boot at 1.8v?

Option 2 is your best bet if you can keep it stable, if you have to you can bump the vcore up a little bit to keep it stable if you have troubles. 1.8v will be fine for your RAM if it's stable, if not bump the voltage up just a notch and see.
