OC 1.6A, go for faster CPU or faster memory setting?

[WhiteMouse]

Here's my set up:
P4 1.6A + PC133 SDRAM. Mobo does not lock memory based on FSB, but let me select CL timing and PC100/133.

So at 133 FSB, while chose PC133, my memory was running @177@CL3. It passed Sandra memory burn-in test (12 hours), but failed on Prime95.

Now I have two options:
1. Keep 133FSB, set memory as PC100 and CL2, so it will run @133@CL2. CPU@2.13G, VCore 1.55V
2. Lower FSB to 125, leave memory as is, so it will run @166@CL3. CPU@2G, default VCore

Which way should I go? The first option will give me faster CPU (may set even faster), but slower memory. The second option does not use full power of my CPU, but provides better memory bandwidth, which is the weakest point of that P4 NW+SDRAM set up. PCI will be slower too. But it can be done in default VCore (on my mobo, the reading is 1.4V?), so I will be able to run my CPU cooler.

Any suggestions? Thanks.

go the cas3 route. keep the mhz.

cas2 on a i845 sdram system barely makes a diff at all.

<EDIT> thx for the GATOR link in your sig too - shall i kill you now...?

uh wait, i read that 1st part wrong. (musta been your excellent explaination) 😉

tough choice - keep the 3:4 memory ratio and do the best ya can.
with some luck they may some day give you a 4:5 ratio @ 133fsb. (=166)
can you adjust memory voltage? (3.3v)
bump it upto 3.4v or 3.5v.

what board are you running anyways?

*still :| about that gator link

Thanks. And sorry about the gator. The sig was left for a family member. I had not visited that site for long time until today. Got the gator warning too. I've seen that before, it is an ad ware, isn't it?

The mobo I am using is Shuttle AB30, no memory voltage adjust.
