my phenom 965 c3 clocking

uscool said:
it just crashed :mad: its CPU clock on default 3.4ghz, auto cpu voltage, i set NB freq to 2.6 and changed CPU-NB voltage to 1.26 and it crashed why is that ? ram running at 1600mhz

mine needs 1.275v but each chip isn't the same.. each chip need more or less voltage.

what your temps at that?

Everythings on auto cpu clock, voltage, only changed the CPU-NB voltage now to 1.275 and NB frequency 2600MHZ, rams at 1600mhz, the motherboard temp is 25c idle, the cpu cooler is not very good at all, its a arctic extreme, i ordered the scythe mugen 2, look at this review comparing the arctic to mugen 2 like 20c difference on load :rolleyes:

im gonna start trying to overclock it when i get the new cooler,i will be happy to get it running at 3.8 ghz i would settle for that,

so do i only change CPU multi + cpu voltage, CPU-NB voltage in trying to overclock it ? right ?, will be happy and gratefull if you could help me, going to sleep now so tired

Thanks

yes

start of just uping the CPU multi then when you've found the limit on stock voltage, start to up the voltage by +0.025v then try uping the CPU multi again then when you've found the limit go back to the voltage and add another +0.025v . just keep doing that. remember to watch the temps and don't go over 1.5-1.55v.. test the clock using prime95 on blend setting for a good 5-8hours & use LinX or IBT on maximum/all for 20-25 runs just to doublely make should its fully stable.

after the clock is stable u can start doing the NB clock

The new bread AM3 CPU have a built in memory controller so NB Clock Frequency and CPU-NB voltage are actually areas of the CPU. The only thing you need to be slightly wary of therefore is that an increase in CPU-NB voltage is going to affect your standard CPU temperatures and vice versa.
 
Its set at default clock 3.4ghz with 1.4 voltage, i noticed when its on load looking at CPU-Z, the Core Voltage drops to 1.375v, on idle its on 1.411, is that normal ?

yes its normal.

mine does it the other way round. e.g if i set 1.425v in the bios it idles at 1.408v but under load it goes to 1.424v.

for your motherboard just remember if u want let say 1.425v just set 1.450v in the bios then when it's under load it'll goes to 1.425v.

Thanks , i think i know what to do now, just gotta wait for new cooler to arrive to start doing it, im thinking this is gonna take a week or so of constant tweaking to get it running good, id be happy and satisfied to get it running at 3.8ghz on minimal cpu voltage, with a 2.6 ghz NB, would i not need to change the NB voltage ? only the CPU-NB voltage, lets say i get it to 3.8ghz only changing the cpu voltage and cpu multiplyer, could it reach that, even if you dont increase the NB freq ?

Thanks

yes..

keep the nb clock at stock untll u finished with clocking the core clock.

HI, yes still waiting for cpu cooler, sent 2nd class, taking ages :confused:, just wondering what settings have you got your working at 3.8ghz stable , voltages ? Speed ? (Cpu-Nb voltage, NB voltage, what are your temps

thanks
 
well whats safe normal v for northbridge

got 3.7 stable but 3.8 aint having it and wondering if its the northbridge which wa at stock. what would it need do you think without going overboard
