G3258 overclocking advice
G3258 overclocking advice
Hi, i have read many threads regarding the overclocking of the G3258 anniversary edition CPU, I am new to overclocking and managed to get 4.5ghz after reading other posts on here but the voltage is maxing at 1.317V is this something i need to be worried about as it is used 24/7? I left the voltage on auto mode so i havent changed anything voltage related.
Temps:
29 Degrees idle
62 degrees full load using Prime95
My pc specs:
Phanteks Enthoo luxe case
Antec 1250 h20 CPU cooler with push pull fans
MSI Z97 Gaming-G45 motherboard
16gb ram 1600mhz
G3258 Anniversary
AMD Radeon XFX 280x 3GB
CX750M Power supply
Thanks in advance
1.317V is OK for 24/7. I'd prefer under 1.3V. 4.5Ghz is decent (but not great) for that voltage.
So all you have done is increase the multiplier from 35 to 45?
There's a lot of fine-tuning you might be able to do to get the voltage down (or the multiplier to 46)
I tried 4.6 ghz and it crashed BSOD instantly when running prime95
Seems there is a massive jump from 4.3Ghz at 1.280v and max temp of 57 degrees , up to 4.5Ghz at 1.328v at max 64 degrees ( Double checked now using CPU-Z ) (stock 3.2Ghz was 1.08v max bench temp 44 degrees)
Yes all i changed was the multiplier, im worried about fiddling with the voltages as i know very little and just using google and forums to try and get some knowledge on the area as i go. Any suggestions are more than welcome !
I dedicated a significant portion of the summer to overclocking my G3258s. One achieved 4.5Ghz, while the other reached 4.2Ghz. As you increase the voltage, you'll observe a noticeable rise in required multipliers, and then the process typically ends there. It's possible to extract another multiplier, but it's unlikely.
Running at around 1.4V for brief periods and maintaining temperatures below 80°C won't cause serious harm to the CPU. I often aim to determine the maximum achievable performance.
My approach differs; I manually set the voltage to a safe level (1.300V) for continuous operation, then incrementally raise the multiplier to identify its limits. Once a stable multiplier is found, I adjust the voltage upward step by step.
4.5Ghz at 1.328v appears promising. Consider entering manual mode and setting the voltage to 1.325V to check stability. If stable, gradually lower the voltage until you reach the next threshold.
The extent of fine-tuning is up to you. We can explore a stable Adaptive Overclock and adjust other parameters accordingly.
Thank you for your message. I attempted to adjust the voltage manually in the BIOS, but when I entered a value it displayed red. If I used 1.299 it remained white. I tried 1.310 and 1.299 as well, but after booting and checking during operation they switched to auto voltage. It seems I might be missing a setting somewhere. Should there be an override option for a description in the BIOS? I deselected auto and entered the voltage without success. However, I haven’t experienced any BSOD or issues with this auto voltage at 4.5Ghz, but I’d like to try lowering it if possible! Thanks.
I don't understand either. I'm not well versed in MSI's BIOS for that motherboard. Each manufacturer's BIOS varies slightly. One of the settings now labeled Auto should offer options such as Offset, Override or Adaptive. Perhaps choose what fits and dedicate a bit of time each day to experiment.
I found a solution to my issue by using the MSI Intel Extreme Tuning program. I adjusted the voltage down to 1.295V, but under full load it reads 1.320V in CPU-Z. It’s unclear which reading is accurate. Either way, it’s running Prime95 smoothly for about half an hour without any problems at 4.5 GHz. Perhaps I should accept this result since lowering the voltage would likely cause a BSOD after a short test period. It seems the turbo boost settings are adding extra voltage—trying to tweak them might help.
