Hello. I'm trying to get my CPU and ram to run most effectively. I have a Gigabyte GA-G41M-Combo (Rev.1.3) motherboard, 2 sticks of 2 Gig Crucial DDR3-1333 (CT2KIT25664BA1339) along with a Q8300. My question is, should I run a 2:1 ratio as shown by CPU-Z? I have read where guys set there Memory Multiplier to 4.0D and latch at 266 in the Bios with a similar set-up. With these settings, my system runs quickly. Much better than the optimized settings but I'm not sure if this correct or safe. The system is stable and I have run memtest with no ill results. I fully understand the motherboards lackluster overclocking ability, but again, will a 2:1 ratio create any problems?

Yes, the 2:1 ratio is OK. You are giving up a little performance by not running at 1:1. But by running the memory at half speed, you have removed the memory as a source of problems.

The G31/G41 chipset is an economy, entry level chipset. Unless you get really lucky, you will not be able to push the FSB freq past about 360 MHz. I have a G'byte G41 board. FSB freq of 352 MHz works. 353 MHz doesn't. This makes the G41 chipset a poor candidate for overclocking a CPU with a 333 MHz FSB.

Hey. Thanks for the response. So to be clear, Its okay setting the Mch Frequency to 4.00A and strap it to 266D with my hardware combination?, and, how in the world are you getting a 352 Mhz OC with that Board? I've heard of raising the the Pci Express setting to 104 or so but I haven't the courage to go that high. For my setup, 343 is my max and from what I've read, that's basically the norm. Again, thanks for your response and hope you could enlighten me a bit more.

What's the Frequency, Kenneth?
