When I 1st started, I tried 1.3V and 5GHz I think
All that was over 3 days. It was the 3rd day I tried memtest and realized to not mess with the ram. I was also lowering the Vsa and Vio while raising the Vcore.
So this is only really day 4 of OC adventures.
You can leave most things alone. The actual guide is here:
But I'll sum it up plus how to use p95 at least one more time. As I've said, with so many variables it's really hard to say what wasn't right before but if you follow the guide you'll be able to get your maximum core and cache speed pretty quickly.
Since we aren't going for AVX use version 26.6 of prime, I'm fully aware that you can disable AVX but if the PC crashes there's a good chance it will revert the .txt with AVX enabled.
Reset to defaults.
Enable max current on your board, figure out what LLC does. To figure out LLC use manual voltage at 1.25ishv and use whatever setting seems to keep your voltage close to the set value with a tiny bit of droop. If it's adding to it that can be a very bad thing as it's doing it to the entire socket.
Set cache speed and ram speed/voltage to stock, XMP is not stock so use 2133mhz. Cache should be set in manual mode.
Set a core speed you want, try for the highest one and don't lower it unless you can get it stable safely. I'd shoot for at least 5ghz if you have a decent cooler. 1.4v is very safe as long as you're keeping thermals in check, Intel says you can use up to 1.5v lol Use manual voltage.
Apply a vcore that you think will work based on what everyone else is using and go from there. Crashes and errors means you need more voltage obviously.
Stabilize with P95 26.6 either using Small FFT or a custom test with FFTs in place using size 1344K to 1344K. The latter is good for quick and dirty while Small FFT for an hour or two is what you should use to verify that the core is 100% stable. 100% stable is critical before moving on or you'll have to start over again.
Once you have it stable enable XMP but keep your own core speed. To test the ram for stability use a custom test, don't fun the FFTs in place and use sizes 512k to 1024k (running all the sizes will take a long time). Use 70% of your ram for the test. You can let this run for a little as an hour, more is up to you. The beauty of p95 is the speed of it if you know how to use it.
Obviously you can OC more if you want but this is a good way to test it. VCCIO may help you stabilize tighter timings or higher speed, this voltage is fed to the IMC.
Once the ram is 100% stable move on to the cache. Personally I just set a voltage I'm happy with like 1.3v and start higher with the speed and work my way down. As long as the cache is within 3-400mhz of the core, there is little reason to push more voltage because the cache has a lot of bandwidth. Again, test to 100% stability. At this point I'm done overclocking so instead of running a custom test I'll just run blend and let it go for 4ish hours, more if you want.
The other voltages like I/O can be left on auto, set to Intel's specs or even downvolted but if you're going to change them it needs to be one at a time with some sort of validation after so you know what it's doing.
If you don't feel like going in and out of the BIOS you can use XTU but your final configuration needs to be in the BIOS.
Once you're done stressing set your manual voltages as adaptive or offset for the core and cache.
Not related to OCing but still helpful for improving performance and power saving:
Set your Windows performance plan to High Performance to disable core parking and keep your cores in turbo longer. You can set the minimum CPU state to 5% or w/e if you'd like it to downclock when idle so your adaptive voltage will drop.
If you're using W10 make sure you're using O&O ShutUp10 with at least the recommended settings plus the ones for updates so:
The bloatware can be removed and won't reinstall (like 7)
Your network, ram and CPU usage isn't running wild (like 7)
Windows doesn't decide to update at inconvenient times (you can do updates manually like with 7).
You'll have much faster boot times (not like 7 lol)
OneDrive will finally shut up!
I actually use recommended and somewhat recommended settings plus the update ones.
