View Full Version : BIOS Settings For RAM

12-13-00, 10:09 PM
Besides changing my BIOS between CAS2 and CAS3 for RAM, I also have several options for chip speed. My BIOS is currently set at 8ns. Is the "Turbo" setting any faster?

Also, what affect do the CPU Clock speed +33 or -33 settings have on the RAM speed?

Rarely serious, but always sincere.

+ or - 33Mhz sets the RAM BUS speed either at 100Mhz or 133Mhz

MailmanX, what mobo do you have and is your RAM CAS2 or CAS3? Also, what ns is it rated at and is it PC100 or PC133?

Mobo is AOpen AX64, RAM is Infineon-Siemens 7.5ns CAS2 at PC133 which is what my FSB is currently running. I have a P-3/733 Coppermine. Nothing in my system is overclocked at this time. However, I am starting to learn about it and develop an interest in it.

By default, my BIOS for the RAM is currently set for 8ns, CAS 2, CPU clock speed.

Argh, AOpen Mobos SUCK at overclocking BIG TIME!!!! I have an AOpen AX63Pro and I couldn't even run @ 133Mhz FSB with my P3 550E. I then bought an Abit BX133 RAID 'n now i'm running @ 152Mhz FSB!!
