Intel Pentium G3258 Performance and Owners Club NOW with GTX 970 - Page 120

First time trying to OC on a gigabyte board. I even tried the "EasyTune" software and even the light lama OC to 4.0 ghz was unstable. Should I just chalk this chip up as a loss? Might just buy another g3258 and try my luck again. I could always put this one in my parents computer and run it at stock with the stock cooler and all.


What's the stock voltage? Have you tried using Static voltages in the BIOS, instead of Adaptive? It seems like incredibly bad luck to get such a bad chip, there's got to be something wrong in the settings somewhere.

I'm desperate because i cannot reach 5.0ghz. Can reach 4956 but 5.0 no. Damn. And I use tons of voltage.
I have asrock anniversary z97M (MATX) mobo, and i cannot find input voltage control in bios settings... can someone plese help me with that?
Another thing: Is it normal i cannot choose which core i want on and which i want off?

nicefinly: I do not have experience with Gigabyte z97 but they are great mobo with tons of OC settings, all of them. 4.0 is a ****ty results, and i have a chip that does 4.5@1.41v which i consider rubbish. Before throwing it away try a harder OC and change some auto settings to manual values, maybe there is some power efficency option turned on or some other values to adjust. Did you OC 40core and 40cache ratio?? Leave the ratio to 32 insted of pumping it up and try to go up!

You could try delidding to see if the reduction in temps offers that little extra bit of stability to reach 5.0


Working on fine tuning my OC:

I have tried with a 230W peltier but same results.

What were the temps like with the peltier?

How to Overclock Pentium G3258

Step 1 - Set the CPU uncore ratio (aka CPU cache ratio) to 32
Step 2 - Leave the DRAM ratio, timings, and voltage to Auto.
Step 3 - Set the VccIN (aka VRIN) to 1.900 V and set LLC to highest setting
Step 4 - Tweak the CPU core ratio and CPU core voltage
Step 5 - As you reach higher CPU speeds requiring more than 1.3 Vcore, you might need to increase VccIN (aka VRIN)

1.325 Vcore for 4.3 GHz seems like it wouldn't be worth it. How much voltage is needed for 4.0 with your chip?
post #1198 of 4581
Currently running my CPU on 4.7Ghz @ 1.4V.
Prime95 28.5 is busy and running for over 2 hours now.
Will let it run for couple of hours to make shure it's stable.

Think I'm going to use this processor in my upcomming mediacenter.
Nice overclock to be capable of running games smooth as well!

The cpu is delidded and the top ihs is lapped, liquid ultrabetween the two.
Peltier cooling is awesome for this chip because you can easily go from -14C to -5C (depending of the voltage) in idle and stay around 0C to 10C under load and this is achieved with a good air cooler (i use an EVGA ACX).
The cost is reasonable and if you use the pc PSU with max 15euro you can go subzero but keep in mind the water condensation problem (electrical tape and paper napkins solve the problem in short time, than you must insulate the MB like using phase change).
I used a 230w pelt but within reasonable voltages a 136w pelt does same job.
post #1200 of 4581
Answering the question of peltier cooling, i post some picture.
Temps are from my 4670k, because my ****ty z97 asrock "millenium falcon 20th aniiversary M edition" temp sensor does not go under 0°C.

Quick and dirty Pelt job on 4670k

Delidded 3258K

3258K on DIMASTECH bench, asrock z97M anniversary, 4gb vengeance 1600 and hd5850

Temp results IDLE@stock speed with 4670K.
