How high are those of you with P3 650s able to go?

It seems like I'm the only one here able to clock one of these past 1GHz. I've got my 650 at 1021MHz with 1.8V on an MSI i815E Pro and HSDRAM at 157MHz 3-2-2. I'm using the all copper HedgeHog heatsink. The system is completly stable. I've been running software loops for the past couple days without a hitch. So, has anyone else been able to clock a 650 this high, or higher?
 
I am running my 650 @ 975 on an Asus P3B-F. 150MHz on a BX. Not to bad!!!
Any day now I will be trying my chip on a CUSL2 to see if it will go higher.

been runnin'my 650 at 936/1.75 for a couple months, Alpha PAL 6035, I haven't gone higher, at 936 it flys!
 
They were doing some test with fuse talk version 2 beta 1. They only had that beta running for an hour before they decided to take it down. During the time that the beta was running, I made that text hyperlink.

The CPU is still at 1026MHz. The pic up there shows Unreal at cycle 882 with each cycle taking 51.5 seconds to complete (882x51.5=45423, 45423/(60^2)=12.6175). It's about 12 and 1/2 hours. Prime95 was run to take any of the unused clock cycles, so thats why it's only at #9 in the pic. I also ran the nVidia demo Dagoth Moor during the night last night for about 10 hours and it's still running. This CPU is stable.
 
AdamK37, if that 650 is stable at 1026, that's great! I brought mine up to 866. Gonna leave it there, too. No software I own truly pushes an 866 right now, so why risk harming the chip by taking extreme measures? And even if I did, I'd likely be stuck in the low 900s...not much of a gain. But if I could reach 1026, I might do it. 😀
 
My 650E is at 866@1.85v. I'd crank it higher if only i got better cooling. Right now it is pretty close to melting.

But even with extra cooling, I doubt my it'd get far past 900.
