AMD Athlon 64 3000+ Voltage Confusion

[saurabhvarma]

Hi All!
I am new to the world of overclocking. I somehow goggled and managed to overclock my pc. I have a few questions.
My PC was running stable with a voltage of 1.39 - 1.52 (i have not tried beyond 1.52). So is it necessary to increase the V-Core Voltage to 1.52 or more even though it runs stable at 1.392?
Should I try overclocking the chip further, if I am able to maintain the temperature between 48-52 C (I mean my motherboard allows a max of 400 MHz FSB)?
Also is it necessary to increase the voltage for RAM even if it is running stable at default voltage?

Lastly are the settings below appropriate (I don't wanna kill my chip )
V-Core Voltage: 1.52 volts (Default: 1.4 volts)
External Frequency: 250 MHz (Default: 200 MHz)
Multiplier: 9
HTT Multiplier: 4 (Default:: 5)
CPU Temp on Full Load (using prime95): 49-52 C (Normal: 46-48)
FSB: 1000 MHz
Memory Voltage: 2.6 volts
Room Temperature: 30-33 C
CPU Clock: 2250 MHz (Default: 1800 MHz)
State: Stable (used prime95 for 6 hours and 1 hours of Memtest)
RAM Timings: 2.5, 3, 3, 7 (Default: 3.0, 3, 3, 8)
Motherboard: ASUS A8N-E
RAM: Simmtronics 512 MB DDR 400 (PC3200)
Display Card: Gigabyte PCI Express ATI Radeon X300SE (128 MB; Core Speed: 325; Memory Speed: 200 MHz)

you can't go any higher or give it any more voltage until you get better cooling

50C load is really the limit of where you should be at full load

imho, I would drop $50 on a nice air cooler and case fans, which will give you some more headroom to OC

one thing I noticed is that you'll need to drop your HTT Multi to 3x if you raise the FSB even 1 more mhz. FSB (aka HTT) is what you have listed as "external frequency">> what you have listed as FSB is technically the HTT. so 250mhz FSB x 4 (htt multi)= 1000 HTT. but you can't exceed 1000 htt or bad things can happen, like scrambling your hard drives.

if I were you, I would read Zebo's Quick and Dirty A64 clocking guide just to be sure
