FSB report on POST accurate?

[new2overclocking]

I'm trying to overclock my Duron 800 to basically anything higher that's rock stable. I've been able to get 8x110 (880) just fine, but if I go to anything like 7.5x120 (900), it gets funny in Windows ME. I've tried bumping up the voltage, too. At 8x110, I get (as expected, I guess), a 10% increase in my Sandra memory scores.

I think it might be a problem with the POST reporting the memory bus speed: I've got it set to "Host+33" in the BIOS, which may be why my setting of 120 for the FSB doesn't workn (i.e. 153). That's fine, but why does it report "900 MHz CPU" with "DRAM at 133MHz" on power-up?
I'm running 256MB Crucial CAS2 PC133 memory.

Should I just reset it to "Hostclk" without the "+33" and try it again? I wasn't able to get any Sandra benchmarks with the higher FSB settings.

Why not try it and see what happens and then tell us.

I ran my Duron 600 at 10x100, 1.85 Vcore, with Hst Clk + PCI. I have two different PC133 CAS3 sticks I was running at CAS2. My Sandra 2001 results equalled or exceeded the example Tbird 1000 listed below my results. I was very satisfied.

I understand your comment, except that my connection at home to the internet is marginal at best, and often I can't connect at all. Rather than wait until I can connect, I typically search around for information at work before I go home and try different things. Sometimes this results in my trying to get suggestions before I try to implement it.

I'd rather not try things willy-nilly just in case there's a real problem. I'm not super-serious about overclocking, just want to see if I can squeak a little extra performance out of my system.

You never try stuff willy-nilly. Or should never try stuff willy-nilly. Adjust one item at a time, that way if it works, you know to leave well alone, and if it don't then you know what to set back!

I would seriously try it. Everybit of kit is like a person. All different. Your kit might be able to hack it, whilst others aren't.

I try not to believe what it tell me on POST.

If I believed everything I read, then my RAM would be running at PC100 CAS2 and not PC133 CAS 3.

SiSoft Sandra is usually preferable to what it says after POSTing. Chances are it is because your RAM's trying to run at 153.

I would reset mine to Ram speed to HOSTCLK if I was taking my PC100 over 100 FSB, MY PC has POSTed with the RAM set for a ridiculous speed (168, or somesuch), before I realised the mistake I'd made, and went into the BIOS to reset it to something proper like 126Mhz, CAS2.
