KT133A - 140MHz/140MHz or 120MHz/160MHz?

I've been playing with the overclocking capabilities of my Asus A7V133 and have been unable to run the board reliably at 150MHz system bus. At first I thought this was due to the memory being unstable at this speed. I tried out a stick of 128MB EMS HSDRAM that I've been able to run at 157MHz in an i815 with no problems for months. The HSDRAM even failed at 150MHz, so I began to think it was the chipset that was unable to run reliably at 150MHz. I tried out 115MHz bus and 153MHz memory and was suprised to see it run flawlessly. I then tried 120MHz bus and 160MHz memory and it is still running flawlessly. This is even with Micron PC133 memory that I thought would never run stable at high memory speeds, but I guess I was wrong. The memory is still at 160MHz even as I type this with Prime95 crunching in the background. Previously, I've been running the system with a 140MHz bus and 140MHz memory and have been happy with it. Finding out that I can run at 120MHz bus and 160MHz memory has me wondering if a 140MHz bus would be better having than a 160MHz memory speed. What would you pick?
 
Yep. Thats the one I'm using now. All that BIOS does is change the default system performance settings from normal to optimal when using a bus speed greater than 3% over default bus speeds.
 
Tough call between the two.....
Try some benches with each and see what you get.
I would really have a tough time choosing between the two.
 
FSB is where you get the performance boosts from the Durons and Thunderbirds. I'm betting that the 140fsb is more valuable as a setting than 160mHz memory.
 
I have a KT7a-raid running @ 9 X 146. Does kt7a-raid have the capability to have different FSB and memory speed? If yes where is it?. I looked in the bios but could not figure it out, new to it.
