Want to run 266 MHz FSB on Athlon 1.2

[Doominess]

How's it goin?

Here's the plot, I have an AMD Athlon 1.2 GHz (Normal, not an XP) and it's in an Elitegroup ECS K7VZA motherboard (

http://www.ecsusa.com)

Now, according to the site, the manual, and the manual you can download from the site, this motherboard will do 266 MHz for an FSB, though, I can't find ANYWHERE how to set it to do that...

I don't know much about Athlons at all, I believe they set their multiplir either automatically, or it's locked, but the point is, I figure I'd get a nice speed increase if the FSB was jacked up to 266 MHz... I'm hoping the multiplir will tick itself back, as I don't really want to run the thing at 2.3 GHz...

But anyway, if anyone could shed some light on the issue of HOW I go about this, I'd be more than pleased

The only jumper settings on the motherboard to do with speed are the JP9 and JP10 which do the frontside bus, but only in 100 and 133 MHz...

So I'm completely baffled, if anyone could help, that'd be fantastic... Because me and two other friends have the same motherboard, and we'd all like to get it crankin' at 266... So yeah, if you know anything that'd help, get in touch

Depends which Athlon you have. I'm fairly sure that all the 1.2Ghz are double-pumped (anyone know different?), but some are 200Mhz FSB, and some are 266.

You cannot set the North Bridge to run double-pumped, it won't do it unless it's already DDR. The BIOS settings will only let you set the real-time speed (generally 100-133, with some variation either side, eg 66 - 166).

In plain words, if you set the BIOS to 133, and your processor has a 266 FSB (this is where the "double-pumped" bit comes in), then the processor will talk to the North Bridge at 266Mhz.

If your motherboard is not DDR (Double Data Rate), then your processor will only effectively communicate at 133Mhz. If your RAM is 100Mhz, then the whole shooting match is slowed down to 100Mhz.

If your board is capable of 266Mhz FSB, then it is DDR. I checked your link, and the site lists it as a Via KT133 chipset - which is not DDR, to the best of my knowledge! There is a pair of jumpers, JP9 and 10, which need to be set to run the board at either 100 or 133Mhz.

Whatever, if your board is capable of it, then setting the FSB to 133 will make it run at 266 IF it is DDR. The only thing that will show this is diagnostic software like SiSoft Sandra.

I hope this makes sense - the issue itself is quite simple, but explaining it is a bit like explaining the off-side rule in English Football CitrixEngineer@yahoo.co.uk

1.2 Thunderbird Athlons came in two flavours: 200fsb and 266fsb.
Most of the earlier ones were only 200fsb and as your motherboard does not support DDR memory anyway, you definately won't get the processor running at 266fsb even if it could.
Even boards that support DDR memory only have this 100 & 133 setting, it is the DDR (double data rate) memory that effectively doubles the 133 to 266fsb. Martin Just trying to help, sometimes falling short, I am only human after all.
