I've bought my new pc 3 months ago and i desided to overclock it like the ones before. Now i have an serius issue. People say they easly OC i5-750 on 4ghz. I oc it on 3.80ghz and i'm getting temps at crysis warhead at 65-66°C. with prime about 67°C.
Now i tried to Downclock it on 9x multipler (190mhz bus speed) so 1700 mhz and 1.088v voltage. temps dont fall below 45. at my previus cpu Q9400 at oc 3.52ghz i had 40°C iddle and 62°C full load. Now 50 iddle (at 3.8ghz) and 68°C full load. is that ok or not?
I'm using ZALMAN CNPS9700 cooler.
I have an Gigabyte P55-UD5 mobo, geil rams 1600mhz DDR3 4gb, HD5830, Lc power supply 750W and chasis with 7x 120mm fans.
i see that your cooler has 6 heat pipes total......mine has 6 on each side.....this may be a sign to upgrade the CPU cooler....once you break the 4GHz barrier its kid of hard to keep the temps in check...
clean your HSF with detergent let Drying, clean fan insert thermal, install again
let your chasing open up don't closed, we know how drop temperature.if temperature not DROP it mean your HSF not Suitable for OC processor, keep it & buy New HSF for OverClocking sutable Intel etc, Noctua, Sunbeam, Shynte probably your money
yeh i've done that already first time that i installed the cooler. I actualy have 1200 RPM limited FAN speed becouse it gets VERY laud at 2800 RPM. anyway now i've OCed to 4ghz and i'm getting at full load up to 70°C thats alittle too much i belive so i'm thinking to lower on 3.8ghz wich is okey too.
My settings for 4ghz:
CPU vcore: 1.375
cpu advanced control: 700mv
somthing else control : 800mv
bus ofc 200mhz speed
ram 1600mhz atm
all other settings for voltages on auto
almost all cpu features turned off. C3 state and those aswell
good to hear that you got you temps under control!!!! haha anything under 70*C under full load is nice and dandy.
always start with the foundation when you are trouble shooting heat issues with your CPU and GPU.
If you think its not worth the extra nios then dont disable the smart fan.....anyway with it active if your temps go up the RPMs of the fan will as well to cool better but if you want comfort then go for it
i guess I am a lil biast to Coolermaster cause they have never let me down. I have the V6GT and it works wonders and im at 4GHz + on my 1156 based i5 but generally you should look for a cooler that has a large heat sink and the more heat pipes coming from the base plate the better heat transfer you will get so it will cool better. also look for high flowing fans on the cooler.....the more air flow the better it will dissipate the heat from the fins to the ambient air..
if you feel Ok, test again your OC with Intelburtest20X, OCCT Linkpack 1hour, Prime95 2hours, if one software test say Fully Stable your OC... yes all right!
for your overclock to be truly stable Prime95 should be run for 24hrs but i say 6 without crashing is stable enough! if you can carry out CPU intense applications and not have it crash then you will be ok.....
i have seen OCs that last 4-5hours stable and then crash due to starving the CPU of voltage just by a little bit.
