Overclocking; Raise cpu ratio OR base clock ?

[Cheeseburger Walrus]

Right now it's at 35 x 100mhz

Should I just raise the multiplier or do I raise the base clock... what's the difference? Should I do both? I'm a huge noob to this.

what cpu?

if its unlocked, raise cpu multi
if its locked, and not intel 1150/1155 raise fsb

only bclk that can be rasied safely is 1156/1366 cpus

What's your specs?
Motherboard, CPU, RAM

It's a i5-4690k
motherboards not anything special just msi z97 pc mate

So if I want 3.9 or 4.5 ghz either way I should only touch the multiplier (I doubt I'll go to 4.5 tho I just need a bit more power while streaming)

Lock in your DRAM mode w/ XMP Profile#1
Raise the Multiplier / Ratio for CPU; leave the rest alone.
If the OS refused to boot, gives BSoD or u encounter errors after reaching desktop; chances are the OC is not stable. Then reboot and lower til stable.

Look up your motherboard for an OC guide.

what cpu cooler?

with 4690k, just raise the cpu multi and core voltage as needed
go in small steps and test

if its unstable and temps stay cool (under 80c) raise the core voltage 1 step

I really hope no one tells me to "google it" but I can;t find a good one for my motherboard so feel free to link me one if theres a good one but thanks I'll try that!

just a hyper 212 evo, I don't plan on oc'ing too high. Why would I need to raise the voltage? sorry im really new to this

If you raise the base clock it overclocks EVERYTHING, including the SATA interface.
Taking the base clock above 105 MHz is likely to cause massive data corruption on SATA HDD's.
It also would overclock your PCI and PCIe bus, which can cause hardware glitches.

So I would say only overclock current systems by raising the CPU multiplier.

thanks will do

Yes, you need to set the voltage to manual and raise it while you boost the multiplier. Also turn off Turbo Boost. Don't overclock with auto voltage, if you push it too far your CPU is not going to like it.

Stress test on Prime95 for at least a couple of hours. If you BSOD or one of the workers fail, raise the voltage. If your CPU gets too hot, lower voltage and multiplier to a stable value. You should be able to get a reasonable OC and still stay under the stock voltages.
You can use this as a guide, http://images.anandtech.com/doci/8227/5%20i5-4690K%20OC_575px.png but your chip may do better or worse, it's all lottery.

raising the core voltages makes the oc more stable but the cpu will run hotter

[Bad 💀 Motha]

Yes leave the Bus speed clocks alone. You don't want to alter the clock rates for SATA, PCIE, or PCI bus. Just the CPU. Turn off Intel Turbo for when you OC, but leave C1E and SpeedStep enabled. If you want faster RAM, buy faster RAM, then again, u lock in those specs with XMP.

If the OC becomes unstable, raising CPU VCore Voltage may help with stability, but then again, this is the last thing u want to mess with.

Read through some good OC guides that cover setups involving Intel 1150 and Z97 chipset. Plenty out there.

So what's wrong with auto voltage? Will it change on it's own or will it stay at 1.24? Just wondering how it works. Also I clicked OC Genie just to see it's settings and it set the multiplier to 40 and it actually dropped voltage down to 1.2 instead of 1.24

Some processors can overclock well with a reduced voltage, but they are far and few between. Depends how they are 'binned' at Intels end.

Auto voltage can push it to uncomfortable values if you raise the multiplier too much. Setting it manually is safer and you can go down further if you take your time to test it properly. 1.2V is way too conservative for 4.0 Ghz.
