How stable is the unofficial overclocking bios for K7S5A?

[Kung Lau]

Although I went the cheap route and got the K7S5A thinking I would not be overclocking again, it's been a year and I'm itching to boost CPU performance up a little. I'm going to be getting an ATI 9500 pro or GF4-4600 soon, and don't want my AMD 1.4 becoming the bottleneck. I have crucial pc 2100 ram, and was hoping I could overclock the FSB a bit. I'm pretty sure I can muddle my way to flashing my board with the overclocking bios but was wondering how stable the patched bios was.

My board has been extremely stable unlike some other horror stories when the board launched, and wouldn't want to jepoardize stability for speed at this moment.

What's the best cpu at the moment for performance gain, the 1800xp B, 2100xp B?

Oh, and I have an older SK-6 with 80mm panaflow and don't want to raise noise levels any further.

Thanks

I've not had any problems going from the standard BIOS to the Cheepo BIOSes

Me neither, running my HTPC on CheeboBIOS at 143MHz FSB 24/7...granted I'm not doing much on the system all day long except watch DVDs, listen to mp3s, watch some TV with the TV tuner card...etc...

As an alternative the the Cheepobios, you might want to look at the HoneyX bios at this site. I've not tried either, but just wanted to give you an alternative. Good luck.

Have there been any bios that allows for multiplyer adjustments on the K7S5A?

The board has no software control over multipliers. To adjust multiplers you have to modify the motherboard.

According to the description, the BIOS is not rewritten. What Cheapo does is show the bus setting selections that have been hidden. He also very slightly altered some of the clock speeds. IAC it works OK on mine.

You will still have the problem that you will often need higher voltages to OC higher. You can mod the voltage bridges on the CPU.

BTW 166MHz FSB does not work in any BIOS so far, the last time I checked.

No. There is no hardware on the mobo to do it. Mobos which set the multiplier have circuitry going to certain CPU pins in order to do so.

Mine was very stable at @147fsb, my 266's Nanya's maximium. T-bird 1.4@1.54.
Intiailly used Motherboard Monitor to adjust FSB at start of windows, then switched to CheapoBios, very stable and fine.

The system still runs now Just not at 1.54, 1.4 as the family wont be able to make that much use of it, and its INCREDIBLY stable, gaven to family months ago, not one problem

cheepobios is fine check my sig.

oh yeah I should change the ram, i have 1gig of it now

also , multiplier isnt changable in bios but you can fool around with bridges on cpu itself
