K7S5A FSB/Divider

[clicknext]

It seems to me that some people here have the ECS K7S5A and are able to change the FSB in small increments (like 5 mhz or something). This is not the case with me; the only thing I can select is 133 or 100. I have the latest bios. Is there something I'm missing out on? How are people doing this?

Also, does this board have a 1/5 divider at 166mhz?

you need overclocker's bios
ecs doesn't come with overclocking feature in bios

You can get overclocking BIOS for the K7S5A at this site. link= http://www.ocworkbench.com/ocwbcgi/ultimatebb.cgi?ubb=forum;f=35;hardset=;start_point=;DaysPrune=
I am using them for the faster ram timing only and have had no problems. I picked up 7 to 8% with them.

why, why did they have to tempt me like that?!!!! I got the K7S5A so that I wouldn't, so I couldn't try to overclock my processor.

Does the overclockers bios have a 1/5 divider at 166? I don't want to kill my HDD or anything...

No divider on this mobo period.

Going above 133 will o/c the pci and agp cards, etc.

The good news is , you won't get much past 138 or so!

oh that's just great lol.. no point to getting the overclockers bios if you cant overclock much anyway... maybe I'll get a better motherboard with some of my spare money... or maybe I'll just leave that old tbird to rot.

I'm not so sure about that...have a look.
at fsb 133, divider is 4 (pci 33). at fsb 150, divider changes to 5 (pci 30).

movinslow...good info.

Actually the "no divider" isn't totally wrong. This mobo has its FSB limited to the PLL that specifies the speeds. This means that while there isn't a "divider" that you can change, there are "effective dividers" depending on the PLL. That all said, when you're running at 166/166 like I am, both the PCI and the AGP bus are running at spec speeds.

In addition to the OC BIOS, some people use Speedfan to reset the FSB.

Are they or aren't they running in spec?
