P4B266 help, please

[Lioness]

I have crucial PC2100 2x256 sticks ram. This is a 2.5CL. The BIOS "SPD" sets my ram at 2-2-2-5. I don't see the 2.5T setting. However, it can obviously be changed manually. Should I change this to the correct setting of 2.5T? What is the BIOS telling me? If I understand this correctly, does this mean that my pages load faster at 2T than at 2.5T?

Also, I'm not sure if this question belongs in this forum, however it is related to the P4B266 BIOS. My Visiontek Ge3Ti200 is flashing during XPpro bootup. The BIOS is reading this video card as Video memory cache UC; Delayed Transaction "disabled"; I set it to AGP: 4x; and aperture to 64mb. Should I leave everything else alone? My refresh rate on my monitor is 75mhz.

thanks for your help

What 2.5T means is its the latency of the RAM. If it says 2.5 that means it has to wait 2.5 CPU clock cycles before it can do another transfer; 2.0 is a lower latency setting (and therefore faster). So if its running 2-2-2-5 instead of 2.5-2-2-5 then it shoud make the system run a TINY bit faster, like .5-1%. I definately would not worry about this.

I currently have my Crucial PC 2100 2.5T running at PC 2700 speeds using 2-2-2-5 settings (the fastest/best) with zero stability problems whatsoever! This is excellent RAM, and can run 2-2-2-5 at 133 MHz (PC 2100) with zero problems.

I'm not quite sure I understand your video problem (although it does belong here or Video, either one, because it is in the BIOS). The refresh rate should make no difference. The BIOS setting should be fine. Is it a real "problem" (ie does 3d not work for you or something) or is it just some weird check before the motherboard POSTs?
