OK, I got a new XP 1900 from Newegg yesterday. Here is the stepping.

AX1900DMT3C
AGKGA0142MPMW
K0100XXXXXX

A week 42 'K'.

Its been cranking on Prime 95 at 1.84 ghz (153 FSB X 12) -- which I should be satisfied with, but I am not. Its currently running at 2.15 Vcore (but under the load of Prime it drops to 2.06 Vcore). Temps are good -- 44c under full load (28c on NB, and 23c ambient). I water cool -- so I am not really worried about the temps at these high voltages. At 1.84 ghz -- it breezed through 3dMark2k1. Here is the score --8341 -- vid card at default speed (http://gamershq.madonion.com/compare2k1.shtml?1983437).

It boots into windows at 154 and 155 -- but hangs when I try to run 3dMark2k1 -- maybe after a little burn in it will perform better.

Well the good news is that 1.84 ghz seems rock stable -- it has been running prime for over 10 hours now and no rounding errors or lock-ups. I left it running and am at work now -- we will see if it can go a whole day.

I really think the chip has more in it -- Like I said it loaded windows at 1.85 (154 FSB) and 1.86 (155 FSB) -- but locked up when I tried to load strenuous apps. To me, that is a classic sign of the chip saying "Hey I'll do this work but you gotta feed me -- more juice!!"

Unfortunately, my 8K7A+ is not able to keep the juice at a constant 2.15 (at idle its fine -- but it drops to 2.05 or less under stress). JCViggen had the same problem with his 8K7A+ and found that the KG7 w/ Vcore mod performed far better (probably due to the three-phase power supply on the board). My 5v rail is fine -- never drops lower thant 5.05v -- I did the 5v pot mod.

Anyway -- I think I will probably keep this chip, and maybe see about investing in a KT266a board (I hear good things -- and some bad things -- about the Epox 8KHA+, but I really want to see what the Abit KR7 will do before I decide anything).

I am hoping to eventually get this guy stablized at 1.9 ghz. Any input you can offer will be appreciated
