Hi All,
Well, I got my Phenom 995Z (125W version of the 9950) up to 3.0Ghz, but it was only stable beyond the 1.3V and 61C maximums listed in the processor spec (I had to run it at 1.375V and this produced a core temp around 62 to 63 C under max load.) I used AMD Overdrive, speedfan, and cputemp to get the core voltage and temps. Since then I'm running it at 2.939Ghz and dropped the voltage so I am within spec now. The weird thing is the 9950 has a max limit of 64C, but the 995Z has 61C as its limit. Why? Is it just because of the Wattage decrease?
Does water cooling drop the core temp by any reasonable amount? I know it would drop the motherboard sensor temp, just not sure on the core itself.
Also, I see people saying they got 3.3Ghz @ 1.65V. I know that kills the warranty, but just how much thermal overload and over voltage can I reasonably expect the Phenom architecture to take before I have a puddle of molten silicon on the bottom of the case? Or more directly, I know the warranty is 3 years, which under normal operating conditions (below 1.3V and below 61C) will keep my processor in fine shape. But how far beyond the "limits" that AMD has stipulated can I go safely on the stock cooler? I've seen 1.45V on stock air cooling listed elsewhere but what about thermal limits?
I guess I'm asking is how "extreme" I can go with this processor before I "exterminate" it?
Sorry if I'm rambling a bit here, but I'd like to know how much further I can proceed with my overclocking.

PS I'm running on an ASUS M3A78-T w/ 790GX chipset, if that matters. And 4Gb of Corsair DDR-2 1066 ram.
