How mucg voltage is safe for a .18 micron thunderbird?

[aka1nas]

Hi all,
I managed to salvage enough PC-133 and parts to put together a htpc. I have a 1.33Ghz T-bird with 1.25GB of SD-RAM. This is all on an abit- kt7a raid motherboard. For cooling I have a thermalright SLK-800U with a decent 80mm fan. Currently Temps are around 46C once the rig has been on for a while. I wasn't into overclocking back in the t-bird days so I am not too familiar with the specifics of what this chip can take.

1) Whats temperature range should I be looking at? I know it will prob run a bit hotter than a thouroughbred or barton, but how hot is ok?

2) What is the recommended max voltage on air for this chip?

3) What is a reasonable OC on good air cooling for this setup?

4) For SD-RAM based Athlon rigs, what settings do the most good? Are mem timings that big of a deal? Would OC'ing the FSB(and hoping the PCI cards can take it) be worth it?

stock is 1.7 i think. it should hit 1.8v with no problem except massive heat output. These things were so hot and they were the ones that primarily ushered in the massive coolers.

The t-birds were known to oc fairly well even when undervolted. I have my old 1ghz@1.378ghz (154X9). The stock Vcore was 1.7v and i had mine at 1.55v with the pencil mod to unlock the multipliers.

I checked and the stock on this one is 1.75 as it's one of the higher end speeds. I got it to boot into windows at 1533Mhz at stocks volts but it fails prime immediately. Is 1.8v the maximum safe voltage for this chip?

.18 could probably go up to 2.1V if you can cool it

I'd be comfortable running 1.85V, 1.9 if you can cool it.
