Hello, everyone.
Firstly, my apologies for posting something completely off topic, but this list has always been a good place to turn for just about any problem in the past. Please feel free to mail any replies directly to me so that everyone else on the list doesn't have to be bothered by them.
So, what's my problem ? I am trying out a little experiment, and it is not going as smoothly as expected. I am attempting to run a Tyan Tiger 100 rev. F (S1832DL) motherboard with a pair of PIII-667EB CPUs. This is a BX based mobo, and as such, it is only intended to run at 100MHz FSB. The EB CPUs run at 133MHz FSB. The board has been running for a few months now with a pair of PII-333s, and has proven to be rock solid. In addition to the two new CPUs, I invested in a 256MB PC133 DIMM from Crucial (does anyone believe how cheap memory has gone in the last month ?) and a Gainward GeForce 2 MX video card as they are supposed to handle the overclocked AGP port better than my old Viper V770. The Tyan BIOS is at 2.0.02, and has supported up to 133 FSB since about v 1.18, at least as far as the "CPU Speed" list in the BIOS itself says.
But does the system actually support 133? Just because it's in the bios doesn't mean it's actually being used. Some companies make more or less generic bioses. The other thing is does the bios have support for your cpus? When you have the system working with the other cpus can you get into the bios and set the bus speed or is it only auto? I'd bet the problem the bios looks at your cpus and gets totally confused. It doesn't know what FSB or how much power to supply them. I thought Tyan was pretty conservite about things like overclocking. Even Asus now seems to include overclocking info on thier website. Nick
