help me in overclocking amd athlon x2 4800+

[ankit_arya]

hello guys!!!!
my system has following config:-
amd athlon 64 x2 4800+
asus m2a-vm motherboard
amd 690g northbridge
ati sb600 southbridge
2x1gb ddr2 800 transcend jetram modules
ocz vendetta 2 cpu cooler

the default speed of my cpu is 2500mhz. 12.5 multiplier, 200 mhz bus speed & 1000mhz ht link.

now, i've overclocked it. now speed is 2937mhz, multiplier at 12.5, bus speed at 235mhz & ht link at 1175mhz.
i've dropped memory speed at 667mhz and increased voltage to 2.0v from default 1.8v, my current fsb:dram is cpu/8
i've also increased vcore voltage to 1.475v from 1.375v
this is the maximum i could get at this vcore voltage, now if i increase the bus speed from 235mhz; i've to increase vcore voltage too.

plz help me in further overclocking. i want to reach 3000mhz min with my cpu. i've got that speed but i've to increase vcore voltage to ~1.6v
and i've heard that vcore voltage of more than 1.45v can burn cpu.

my current config is stable with prime95 stress test. and my current full load temperature is ~63c. highest safe temperature for 4800+ is 72c according to amd's website.
is increasing bus speed & vcore voltage also increase southbridge & northbridge temperature?

try asking here: http://forums.amd.com/forum/index.cfm?nocookies=yes

they're much more knowledgeable than me about K8 overclocking.

you'll fry the damn thing!!!! I am impressed with what you have done thus far, you'll still fry the cpu the way you have it now, but it will just take you a little longer. How do i know? Because I have done something similar to my 4400 X2 and now i have an AMD dual core Opteron 180, much better for overclocking. good luck.

Hi ankit_arya,

I've got the exact same CPU AMD 64 X2 4800+
Motherboard ASUS M3A32-MVP Deluxe

Why is your voltage so High???
I'm running my system on 3Ghz now for about 2 months and stable according to Prime 95.. But My Vcore on 1.35V @ 3Ghz and temp under max load is 57C..
My system is stable even on 3.115Ghz but then gettin a bit hot to my liking..
I know it differs from system to system but.. I'm sure your Vcore is too high.

Hi ankit_arya,

Sorry, I got confused with my diffrent rigs! Sorry!! I apologise!
My AMD 64 X2 4800+ Brisbane is Running On 3Ghz stable with Vcore of 1.33V
Temp under max load is 51C

My system is stable even on 3.115Ghz but then gettin a bit hot to my liking..
I know it differs from system to system but.. I'm sure your Vcore is too high.

thanx 4 ur kind replies....
i'll check for vcore voltage now....
