Athlon 266 not hitting 133FSB

[Solokron]

Hey guys!

I have an Athlon 1.2 GHz 266FSB A1200AMS3C, an Abit KT7A-Raid, and 256MB SDRAM Micron True PC133 w/ECC and SPD - Registered 7.5 NS. The system has not problem @ 12 x 100MHz but when I set my system to 9 x 133MHz and save my monitor goes out. After some reboots I will get back in. It will either reset to 9 x 100Mhz or start the bootup but seems to lock right before loading controller HDA. It is not a solid lock because I can still get into the BIOS. Will simply unlocking the processor correct this? I would think that a 266MHz model would allow both 9 and 12 operation. I have a Mini Super Orb and the heatsink is @ room temp so I do not believe it is any issue with heat dissapation. HELP! 🙂 Also. What would be some suggested optimum configs for the ram with this BIOS?

Thanks!

1.2 gig Tbird should be factory unlocked

I noticed you are using ECC ram...I don't think the KT133A boards support ECC..not sure though.

Like I said. It is completely solid @ 12 x 100Mhz. It has the latest BIOS of 2/2001.

From the KT7A Web Faq.

Does/will the KT7 support ECC RAM?
The KT7 will never support the error checking functionality of ECC SDRAM due to the limitation of the VIA Apollo KT133 chipset, although the RAM will work OK. ECC RAM therefore behaves like non-ECC RAM.

So I can't still figure out what is going on with this.

Make sure in the Soft Menu part of the bios you have "Speed Error Hold" disabled...

Oh yah. That is the first thing I did. 🙂 I think it is the ram. I can hit 130 with it and then it eventually craps out. So much for expensive ecc 133 ram 🙂
