Yeah pretty sure its an "A", had to take it down to 11.5X162/32 still running @1863 with a FSB of 324 temps=33 idle, 38 with prime95 going, i guess im happy with it i heard other people saying 1.9 is about the wall for these chips and i hit 1863 with no voltage or memory adjustment and im not on an Nforce board, via kt400 a7v8x best post ive gotten was 165/34@1897.5 wish i could hold it without adjusting my voltages but what can i say im a puss with no money to spend so dont wanna risk frying this chip at all. So i guess ill be sated with this one till the barton prices come down some then its time to drop one of those with a 333fsb and the lower .13 micron onto this board and see where itll take me🙂 prices wont drop until May when the 400mhz bartons are released but hell by then ill have some money and itll be time for a new video card by then too so ill be like a kid in a candy store for awhile, those 2 512 meg sticks of DDR2700 crucial i just picked up are kicking my butt, along with all the fans and stuff i just got for this system im out about 400$ 🙁 all that for cooling and ram and a new PS. The g-froce3 ti-500 im sporting is really shiity, snapped a capacitor off of it,it still works though, however runs frigin hot brings my system temp up by about 4 degrees and that is no good, craving a 9700 pro but cost too much🙁
