About how overclockable are AQGA and ARGA T-birds?

[Electrode]

I've had these CPUs for a while, and I'm still playing around with them to see how fast they will run. They are 950 MHz CPUs, and I'm running them at 1025 MHz right now. One is AQGA stepping, and has a ceramic package. The other is ARGA stepping and has an organic package.

I'm just wondering if anyone has any experience with these steppings, and can give me an idea of how high they can go? Specificly, with the default voltage and multiplier, since this motherboard (Tyan Tiger MP) only supports FSB adjustments.

i had an ARGA Y stepping 1gig(266bus) t-bird that would run all day at 1.2gigs at 1.75 volts with a goldengate 40 and later an AX-7. i could pump the voltage to 1.85 and it wouldn't get me anything more. i was dissapointed at the time as i was hoping for an AXIA or AVIA stepping but a 20% OC isn't too bad.
