I just bought a 2nd hand Abit NF7 v2.0 mobo. I am using a 1800+ HSF for my 2200+. I managed to overclock my 2200+ to 2100Mhz with 200FSB*10.5 at Vcore 1.575v. Temperature is at 42-43degree celcius at normal and around 50degree at high load. Just want to have some comments and ideas here. :) Abit NF7 ver2.0 Athlon XP 2200+ 200Mhz10.5 = 2100Mhz DDR512 PC2700 333Mhz Galaxy GeForce FX 5200 270/443 128MB Windows XP SP2

"I managed to overclock my 2200+ to 2100Mhz with 200FSB*10.5 at Vcore 1.575v" Apparently the multi is unlocked, but I question your vcore claim...it's lower than the default. Your temps are good, but is your RAM also running at 200MHz? If not, you should either get some PC3200 RAM, or compromise the FSB speed to something that both the CPU & RAM can run at...185MHz for instance. Then you can set the multi at 11x, maybe 11.5x. You'll get better performance with the CPU & RAM running in SYNC (both at same bus speed)...I'm guessing you're currently running ASYNC (CPU at 200MHz, RAM at 166MHz?)

When i set the vcore voltage to auto, it automatically runs at 1.50v stable at stock. but the actual vcore is 1.65v. i run it at 200fsb without using 1.65v vcore and it runs stable. i plan to upgrade my ram to ddr400 dual channel 1gb. :) Abit NF7 ver2.0 Athlon XP 2200+ 200Mhz10.5 = 2100Mhz DDR512 PC2700 333Mhz Galaxy GeForce FX 5200 270/443 128MB Windows XP SP2

Get a new video card while you're at it too....

yea...ths video card actually suck. play GTA San Andreas will lag like hell if i set to 32bit colour. but i get this card for free just a month ago. so is it okay for me to run my cpu at lower voltage? btw, i have another qeustion here, i see from the 'Hardware Doctor' and there is a "-12" voltage always not stable and will get negative more than -13v. actually what is the usage of this negative voltage?

Yeah running your CPU undervolted is fine, probably better than running it at stock if it is stable enough. It should also run cooler at lower voltages. I've been wanting to undervolt my my CPU but my mobo wont let me : ( Ussually you just ignore the negative voltages, as long as the rest are within 10% but ussually I wouldent be happy with more than 0.8 volts over.. But I am fussy, and my PSU seems to undervolt most things by 0.3V.

ok... ic... Thanks for replying me. :) Btw, my voltage for vcore and vdimm will mostly overvolt around 0.03 to 0.04. Abit NF7 ver2.0 Athlon XP 2200+ 200Mhz10.5 = 2100Mhz DDR512 PC2700 333Mhz Galaxy GeForce FX 5200 270/443 128MB Windows XP SP2
