Overclocking FSB for the AMD 8350

So I'm working with overclocking using the FSB rather than the multiplier. In fact, I've been taking the multiplier down to keep everything "within spec."

So right now I'm running at 304 FSB X 16 Multiplier with my RAM sitting at around 1292 and it's all great. I want to increase my FSB even more, but I can't seem to get it much higher. I'm shooting to run 323 X 15.5 so that my cores don't get so hot under all the voltage.

My RAM is designed to run at 1333mhz at 1.65 volts, using 9/9/9/24/31/2T.

So obviously, when I increase my FSB up to the 323 that I'm wanting to shoot for, I have to lower the HT Link and NB frequency to stay around the 2200mhz mark. At that FSB speed, I've got my RAM set to the 2nd to lowest ratio, and it's running somewhere around 1200 if I recall correctly, with the HT Link and NB Frequencies still in the 2000-2200MHz range.

I guess my question is, why can't I push the FSB any higher even though I'm lowering the ratios of everything else to keep it all within target range?

When I try and boot, my board LED is telling me I'm getting DRAM failure!

I tried setting the CPU-NB Voltage to 1.3, which is significantly higher than the 1.19 it's running currently at the 304x16 but that didn't seem to help any...

I have pretty nice case cooling and the H100 for the CPU so I've got all of the Load Line Calibrations set to Extreme/Ultra, although the only voltage I have manually set is the VCore, which is set at 1.43 and loads to 1.5.

What's the purpose of running higher NB Freq and HT Link speeds if my RAM isn't surpassing 1333?

If you are overclocking for performance gain than combination of multiplier and FSB is better. FX processors have MC of 1866MHz and going too far off, either up or down, produces strange results.

Watch out for MC, it has only 2 lines and when you use up all memory slots it can cut down on possible OC.
