I have amd 4200 + with Asus m2n m motherboard
But I am not able to get even 2.4 ghz mark.
After rebooting the error message says overclocking failed.
What to do yaar?
ok u did'nt say all the bios settings u tweaked but lemme try....
1st in the bios turn off cool n quiet..
set multiplier to highiest value....
now what i think that when u r oc ing , u r exceeding the ht speed (in bios says probably ldt frequency). u must always keep ldt bus = 1000 mhz.
so go to ldt settings and set it to 800mhz.
now return to the cpu settins page and set fsb to 250.
logic is at default settings, ldt is 1000 and fsb is 200 . so ldt multiplier is 1000/200(fsb)=5
when we set fsb to 250 , ldt at default becomes 250 * 5 = 1250 .we need to strap it to 1000.so change the frequency to 800. then it will b 4*250 =1000.
so if your highiest multiplier is 11,now cpu will run at 250*11=2750. i.e 2.75 ghz!
now go to the ram settings. if you are using 800mhz ram, u may want to set it to manual timing and run it at 667mhz . (if your ram is of reputed brand like corsair/kingston it may support this overclockin and you may run it at default 800mhz.mine is transcend 800mhz and runs fine at 800mhz + extra 100-150 mhz overclock)
note i have not tweaked the cpu voltage settings . this shall stay stable at default voltage.(mine does). run orthos or super pie for stability test.
so lets revise the final specs:
multiplier-- max
cool n quiet -- off
fsb -- 250 mhz
ldt freq--- 800 mhz
ram--- manual-- 667 mhz(in case of a 800 mhz ram)
hope that helps!
re: m2n is not an overtly oc friendly board so you may try gradually tuning the multiplier and fsb settings... if voltage tweakin options are provided ,you'l may try tweakin them at last but be cautious and patient because of the motherboard limitations.
