Overclocking a Core i5 3570k

[Mussels]

Will it really change anything? I kind of confident in my overclock right now and I don't want to muck things up.

if you can shave 5-10C off your load temps at the same clocks, why not give it a try?

Here's my 3570K non-Vcore voltage settings:

CPU IO
1.0500V

CPU SA
0.9400V

CPU PLL
1.5000V @ up to 4.7 GHz
1.5500V @ 4.8 GHz(highest 100% stable clock)
1.6000V @ 4.9 GHz
1.7000V @ 5.0 GHz(highest semi-stable clock)

Other voltages:

DRAM Voltage
1.6030V

PCH 1.05 Voltage
1.0500V

Notes:

• Base clock @ 100 MHz
• 16GB(2 x 8GB) DDR3 2666 @ 2400 MHz
• Delidded with CLU under the IHS.
• 120mm AIO water cooled.
• Setting the CPU PLL below 1.5000V locks up my system(makes the screen go black and requires a hard shut down). Keeping the CPU PLL as close to as possible, but not below, Vcore seems to work best(most stable).
• Internal PLL Overvoltage: Enabled("Enable Internal PLL Overvoltage for K-SKU CPUs to get better overclocking capability")
• CPU Core Vdroop Offset Control: +100%("Higher offset percentage will be more helpful for extreme overclocking.")
• Digital Compensation Level: High("With option High it provides better performance on current stability while overclocking")
• CPU Core OCP Expander: Enhanced("Expand the limitation of CPU Current Protection. For extreme overclocking purpose. Warning: Expanding the CPU OCP limitation means less protection to the CPU.")
• CPU Core Switching Frequency: 2x("Increase PWM working speed to stabilize CPU Core voltage and minimize ripple range. Warning: MOSFET will be hotter when the value is higher.")
• OverSpeed Protection: Disabled(no clue what it does)
• Enhanced Turbo: Enabled(keeps all 4 cores at the same clocks)
• EIST, C1E, Intel C-states: All disabled
• This is my second 3570K in the same system(the first one I "accidentally" fried with 2.2V Vcore). The second one does need slightly less Vcore and CPU PLL to be stable at the same clocks as the first. But the first one, also delidded with CLU under the IHS, was 100% stable @ 5.0 GHz(until I killed it).

I'll have to think about it. Having a closed-loop water cooling kit kind of negates the whole temperature issue since it can handle the heat output and then some.

I will say one thing, having an extra 1 GHz of clock speed is helping a lot. Even in Windows with general multitasking. Virtual machines no longer bring the system to its knees. Now I understand when people say... Clock speed matters.

And this is why i totally love the 3xx0 series CPU's - every last one of them overclocks to some extent (at least 400mhz, some do more with the right board), and they've only gotten cheaper with time

And with the Asus P8Z77-V motherboard that I have in this thing along with the liquid cooling this chip can really fly. I just kind of wish that I had gotten the i7 instead of the i5 when I built the system for the additional hyperthreading threads.

But overall it's a nice boost in performance, a free upgrade.

Looks great man. As far as i5 vs i7 having had both, not a big deal. For Ivy daily, I usually just aim for the best I can get under 1.3v and 80*C. Sandy and Ivy are easy processors to overclock, just bump the multiplier and offset a tiny bit and you're done. I'd recommend doing offset overclock rather than manual. That way you use less voltage when you are idle in windows. I also don't use any load line callibration I just give it a tiny bit more offset.

Overclocking helps a lot in Starcraft 2 more than any other game I've done.

Voltages are still at 1.275 for the CPU and it's been a week and a half with the processor clocked at 4.4 GHz (vs stock 3.4 GHz). I've been using the system for gaming and several virtual machine sessions and the system is stable, no BSODs. I call this overclock successful.

Getting an additional 1 GHz out of this chip has breathed in life into this system. Who would have imagined that an additional 1 GHz would improve things so much? I imagine that I'll be able to keep this system for another year until perhaps Intel Cannon Lake (whenever the hell that comes out). Now I just need a new GPU but damn the prices are high. Damn miners.

It is a good boost in performance with that extra 1Ghz, this should be enough for another year or so even if you get a new Videocard

just like me, you now have the problem that most new hardware is actually a speed downgrade - short of going ryzen for more cores (but not faster per core), or going extremely expensive with a modern intel K chip :/
