quick oc question

[phill1978]

hey,

i have 1055T amd 6 core. I also have 890gx board from gigabyte UD3.

so far all i have done is raise the multiplier value from 200 to 230 etc.. i cant get it to boot at 4.0ghz properly, but always when i choose 3.8 - 3.9 it always boots seems totally stable and never rises above 43deg in all tests.

what else is required to get a stable 4.0ghz, any voltage? and what amount

cheers

have you ran any stability test to test this overclock?

yes prime 95

3.8 and even 3.9 seems fine

I ran out of stability at 276fsb equating to 3.86MHz on this board and although sure it was some voltage tweak required, did not pursue it further. All volts were on auto. My memory was at 5.33 x 276 = 1471MHz, it is running now though at 6.66 x 250 = 1667MHz quite stable.

Am happy to run at 3.5MHz though as a 24/7 OC

thanks nkata,

makes sense, seems like the same as iam getting. what multi did you set? mine was auto or 16.5, i suppose you lowered the multi and increased the fsb?

how do you untie the mem from cpu or is this not poss? at i do get some obscure memory speeds when playing with fsb like 1846mhz it runs ok on this and its only cheap ddr3 dual chan 1333mhz mem

i think im gonna stick with stock cpu for now with 1600mhz mem on x8.00 multi and my Gpu is quite well overclocked

it plays everything very fast so why push any further just yet

 

[Hagar]

I use 14x multi on the CPU and just up the fsb to 250 for day to day use.

This means.

CPU 14x 250 = 3500MHz (25% OC)
HT 8x 250 = 2000MHz (as standard frequency)
NB 8x 250 = 2000MHz (as standard frequency)
Memory 6.66x 250 = 1665MHz on 1600MHz ram
Cool and quiet on
All volts on auto

runs very well at these settings, andy.

do you use amd c1e ?

i have this disabled as my last power supply (corsair 850w) had buzzing caps and i read that amd c1e will effect this more due to the power fluctuation and i don't want it to happen on my new power supply


cheers m8 will give this a go


edit on x14 the cpu fan was modulating, on 14.5 it mirrors your values and is fine but displays 3.6ghz so i will stick with this for a while
