Today i spent some time overclocking my Processor. First time doing such and i cant say i understand everything that goes with it, but i am going through a learning process.

System specs are:

AMD Phenom Agena 9500 OC'd to 2465Mhz
Biostar Tforce TA790GX A2+
Powercolor ATI Radeon 4850 512Mb
OCZ 4GB (2x2GB) DDR2 800Mhz/PC2-6400 Memory GOLD DUAL CHANNEL
Arctic Cooling (AC-ALP-64) Alpine 64 CPU Cooler
Antec 300
Arctic Power 600W PSU
Seagate 500GB Hard Drive SATA II 7200rpm
2x Antec Tricool 120mm Intake case fans from the front
Vista 32 bit OS

I used AMD Overdrive at first, unintentionally this looked to work out my max CPU frequency at 224, so i updated the Bios and set the Freq to that amount. Has run Prime 95 and AMD Overdrive Stability tests fine.
Thing is, in CPU-Z i can see the Multiplier jumping between 5.5 and 11 (11 being the recorded setting) and i cannot figure out why. Is this a sign of instability?
Speedfan reports that my CPU isnt going above 35c and AMD Overdrive actually took the processor upto mid 2500's

Its kinda late and i cant think what other info to include. My RAM comes at 6-6-6-18 and is advertised to run at 5-5-5-18 with an Voltage increase so im going to go and sort that out, looks easy enough.

To update, when i reset my system after all of the above it took about 10 attempts to power the system up.
Fans were spinning, there was a red LED up on the 4850. Not sure if the HDD was spinning, i kinda thought to check that after i got a succesful boot :D 
Regardless i set the RAM timings in the Bios



Believe thats right, upped the Voltage to 2.0v as well.

3D Marks @ Default settings. Seems very low.

Sorry, 3d marks here. Toms forums doesnt let me edit or delete messages for whatever bizarre reason....very annoying.

I would say you need to disable the cool and quite feature in your bios as that would be the only cause of the multiplyer jumping around that I know of. I ran mine on 3d mark 06 and my cpu score was 2930, so at load it must be running the right multiplyer.

However my overall score with the 9500 is 10% lower that what it is with my X2 5000+ black edition with similar set up
