Asus A7V | Duron 650@900 | SiSoft Sandra 2000 Professional

[Jaraxal]

I have a question or 2. I have an Asus A7V rev1.02 Bios 1004 with a Duron 650@900. The bus is set to 100MHz. The memory is set to "optimal" in the bios.

When I run SiSoft Sandra it says that my CPU speed is 909MHz, by memory speed is 152MHz, my CPU Core is 1.92v, my AGP bus is 102MHz (4X =408MHz), and my PCI bus is 51MHz (1/2 multiplier.

Now these things can't be right, can they? I have all my settings to default other than the voltage (which is JUMPERED at 1.85v) and my CPU (which is DIP SWITCHED to 9X100MHz).

Can someone explain why the other value don't match up. Perhaps this is the reason I can't get over 900?

^ Anyone?

try some other programs like wcpuid and those utilites from h-oda, and see what do those programs say.

 

[Jaraxal]

Well WCPUID v2.8 is showing 908.09MHz (201.80MHz bus). WCPUCLK v1.3 shows the same.

So I guess my machine is automatically overclocking it's bus speed....

Now to figure out why!

The "funny" thing is I have 2 identical machines doing the same thing. I have confirmed jumper and dip switch settings in the manual ...

^^BUMP^^

I know the forums are busier during the day so ... has anyone any ideas? Or perhaps have seen similar problems?

mind also reports 908. I think Asus did this intentional so their board seems to bench faster when compare to other.

The default bus speed of A7V is 201.76<hz as shown in wcpuid, *maybe* that's the reason why A7V is faster than KT7.

 

[Jaraxal]

It would seem strange that the default would be higher than what it is &quot;supposed&quot; to be. Perhaps ASUS is guilty of a little &quot;tweaking&quot; ???

I am pretty happy with my stable 900(or 908)@1.85v(1.92 sometimes depending on what you messure the voltage with) ...

Perhaps I should have gotten the Abit KT7...

That's exactly what abit has done three years ago, at the ages of Pentium 200mmx, they set the default bus speed at 68Mhz but display the setting as 66Mhz, so that they lead in many benchmarks and get some reputation. But later, they was caught cheating.

I get the same results in Sandra regarding the too high PCI, AGP and BUS. I just figured it was a detection error by sandra. My system used to occasionally reboot and then if I went into bios it would report that the PCI bus exceeded the RAM bus error and it is in 100/33 safe mode. Weird, because I never touched the FSB when it would do it. What is even stranger is how my system is 100 times more stable with my memory set at 142mhz 7ns and 2,2,2 !!! This vc133 stuff is pretty awesome. I have mine set at &quot;optimal&quot; 4x AGP, and fast writes enabled whereas many guys are saying it is a source of conflict. I am just lucky I guess.

Did you try slowing your memory down to pc100 and setting it at 3,2,2 or 3,3,3 then trying for a 9.5 multiplier? I'd rather have the 900mhz and pc100 at 133 myself though. You should be happy with what you've got.

Maybe try going back to bios 1003 if you are not using win2K or don't have ata100 issues. I get a lot better results with 1003 myself.

Read the readme and FAQ in Sandra. They've stated explictly that the latest version has problems with the KT133 chipset, especially Asus A7V. KA7 (is it?), the version from Asus using the KX133 chipset works fine but KT133 had some changes that messed up their code.

I guess turbo mode is enabled automatically. Maybe this has something to do with the optimal/normal setting in the bios.

As i know, there's a 1% difference. Cause when i have 7x multiplier, 100Mhz FSB, i get 707Mhz. At 8x, i get 807.1Mhz, at 9x, i get 909Mhz. At 10X, i get 1009 or 1010Mhz (can't remember exactly)
