PC100/133 question...

I just built a system utilizing the ASUS AV7133C board and the AMD 1.3 gig Thunderbird CPU. Also installed 256megs of PC133 SDRAM memory. Everything works just fine, but I noticed in my BIOS settings that the CPU Frequency and the DRAM Frequency are both set at 100 Mhz. Shouldn't those both be 133 Mhz? If so, how do I make the change? I can change the Operating Frequency Setting from "Standard" to "User Define", and change the settings manually, but I don't want to mess something up. Thanks... Jim

DRAM frequency should be set to 133. As for the CPU frequency, well I think it should be set on 133 for a 1.3GHz CPU but I'm not sure. You can't do any harm by changing it and seeing if that works. -- Damien Smith [email hidden] ICQ: 77028579 F1 2001 rank: +35.325

Is the cpu a 1.33c? Take note of the C. C means it is meant for a 133mhz FSB. The 1.33 came in both 100mhz and 133mhz versions. If it is C, then yes, those bios settings is what controls the FSB frequency. My motherboard uses a dip switch on the mb to change that option, it varies from various manufacturers. But I believe Asus uses the softmenu system (controlled through the bios). Another thing to take note of is the AGP divider. When runnung on a 100mhz FSB it should be set to 2/3 (66mhz), when using a 133MHZ fsb it should be set to 1/2 (again, 66mhz).

Ok...thanks. The CPU is the "C" I guess because it's rated at 133. In the BIOS, I changed the CPU and DRAM Frequencies to 133 Mhz. I noticed a "Voltage" option. It was set to "10" for 100 Mhz.. Does that stay the same for 133? Also...where do I find the AGP Divider setting in my BIOS? I've looked everywhere. Thanks again...

I meant "Clock Multiplier"...not "Voltage". Jim "Jim Tester" <[email hidden]> wrote in message news:a3rnkb$flb$[email hidden]... > > In the BIOS, I changed the CPU and DRAM Frequencies to 133 Mhz. I noticeda > "Voltage" option. It was set to "10" for 100 Mhz.. Does that stay thesame > for 133?
