i5-6500 overclocking limits
i5-6500 overclocking limits
We can try to overclock the non-K Skylakes, which should make the entire range more exciting.
I'm just starting out with this and only managed to reach 3840MHz by boosting BCLK to 120MHz using my Corsair Vengeance LPX DDR4 3000 at 2880 14-16-16-36.
I want the CPU to run above 4GHz, but it doesn't boot when BCLK is set to 125MHz.
Do I need to adjust the voltage or something else?
The system performs well with a Noctua cooler, staying at around 65°C during gaming and just over 30°C when idle.
The motherboard is an Asrock Z170M Pro4s with BIOS version 2.23.
Thank you for your time.
not sure, but locked multi usually means it's at full capacity. sometimes you can lower it. it probably depends on your system support. don't overlook uncore either—it uses MMRAM cache. since the base clock is tied to it, tweak the multi if you need to reduce RAM speed a lot. also verify that your RAM frequency doesn't exceed the uncore's speed or the PC won't boot. on my old i7, the uncore was double the RAM speed. I added +2 to the uncore if I was OC-in or pushing RAM beyond spec with the CPU OC. also, I adjusted the uncore voltage by .020v. on newer hardware, voltages might differ but the approach remains similar.
Only 100Mhz, not a lot.
They claim you can push them higher, but it will be tough to reach even 100mhz.
That's why I recommend the 6600k.
It can easily hit up to 4.5ghz.

adjust the ram settings and lower its multiplier back to the default. then test again. the ram also gets clamped when the clock is set, because it's tied to the cpu's multiplier. increasing the bclk means the ram multiplier must decrease to stay within specifications.
@HEXiT you're correct. I faced the same issue before and resolved it by lowering the RAM speed and then raising the base clock until it matched the standard RAM speed, and now my CPU is running at 4.2ghz xD

@HEXiT yea you are right. I had the same problem which I fixed by setting the ram to a lower speed and then increasing the base clock until I reached the normal ram speed and now I have my cpu at 4,2ghz xD
What CPU and motherboard are you using?

They seem to do it in a similar manner to the old neph parts.
You should be able to reduce your cpu multi and boost your bclk if you want to adjust your ram without losing overall clock speed.
I discovered a fascinating video about BCLK Skylake overclocking using an i5 6400. I think the 6500 would perform even better and be more stable, since it's placed higher in the rankings. It reaches above 4.0GHz.
So I reached 4GHz on 125MHz BCLK with a bit slower RAM, and everything works smoothly. Should be able to go even higher.
How can I adjust the CPU multiplier?
My WD Caviar Green HDD, which is usually off and quiet, started making noises (like a water drop), which is really bothersome since the system is normally silent.
Has anyone else experienced issues with peripherals during overclocking?
