Re: 11. [New] Lower System RAM

72.199.1.251

I actually found matching the RAM clock speed to the FSB yielded the best results. And also reducing latency timings yielded even better results.

For example, the computer I'm building is actually intended to be the workhorse (for my graphic design work), but I'm testing different parameters to see what would be optimal if/when I build a dedicated computer audio transport. So, I have the 2.4GHz Core 2 Duo and DDR2 800 RAM. (With the RAM latency timings at 4-4-4-12 and Memory voltage at 2.0) If I change the RAM to DDR2 533 to match the FSB clock of 266 MHz, it is an audible improvement. But the best configuration so far is when I reduce the FSB to 200 MHz (giving my CPU a 1.8GHz speed and lower voltage) and then changing the RAM to DDR2 400 (which allows me to have latency timings of 3-2-2-6 and voltage of 1.8)

I should also mention I play my music from a RAMDisk (so the HDD is not used at all during music play) and I have all buffer settings in foobar at 0 (I feel foobar's buffering messes up the timing/jitter) including 0 buffer in the ASIO settings. And in my soundcard control panel (M-Audio USB Audiophile) I am able to reduce latency all the way down to 512. (I used to listen to it maxed out at 4096 and 512 is much better) If I eliminate the use of SRC in foobar I can drop the latency even lower (with even better results). But I like the sound of 24/96, so I'm experimenting with offline processing by Voxengo r8brain Pro to create 24/96 WAVs (which allows me to eliminate the SRC DSP in foobar and keep lower latency with my M-Audio). Sounds great. Really 3D.
