wow your chip requires a ton of vcore to run 5ghz or is your vcore that high to get those mem clocks?

The VID is quite high anyway but some CPU need that much. Under AVX load, with differential sensing on the Formula the voltage is around 1.315v. That's without an AVX offset. It's always better on the CPU and temps to run a higher VID with lower LLC.

Decided to delid today after all the gear arrived. Very nice tool, worked well. Not sure on the solder intel used but it is incredibly soft. Like clay.

Anyhow very happy with the results. Brought all cores to within 5c of each other. Was over 10c before. And maximum temperatures at 5.2ghz of 80c on prime95 small fft's, cpu pulling over 200w. Was at 90-92c before after a prolongued run so 10-12c drop from the delid.

Overall very happy, means i can comfortably run 5.2ghz without issue on any workload.

Actual delid was pretty easy although the quicksilver stuff didnt work as well as i'd hoped. Still gently removed solder with razor blade, couple layers of tape on the pcb and polished copper IHS and die with the flitz polish until mirror finish. Liquid metal on die and marked out a rough rectangle on IHS with lm for the die.

Well worth it then, what vcore are you running for 5.2ghz ?

set to 1.325v, shows 1.315v read from the bios however. Which equates to after droop of around 1.275v load. 5.2ghz on 0 avx offset.

I could push further as i know it will do 5.35ghz at 1.4v but im happy at 5.2ghz for daily use

Hello, Everyone. I am new here.

I have a i9 9900k, asus rog maximus formula xi z390 and g-skill 3200mhz ddr4 ram at 3200mhz via xmp. I am using the corsair h150 360 rad AIO in a phantex evolve evoo case.

I want to get an overclock of 5Ghz or 5.1ghz

What are the "safe" voltages I should put down for this?

moorhen2 · 7 Mar 2019 at 12:15

Yes 7 seems to be the sweet spot, not too much vdroop under load, but just enough to stabalise the required voltage.

Welcome.

You will only find out with trial and error, no two chips will be the same, have a go with the AI Overclock utility, this is pretty good at giving you a baseline to work from, it will generally give a higher vcore than is probably needed, so you can always tweak things.
Have a look at the guide I posted on page 65 of this thread, about hallway down the page.

You basically set your bios to default settings by pressing F5, then reboot and and run a stress test for at least 30 minutes, like Realbench or Aida64, then go into the bios again and set AI overclock and this will give you a core frequency with and without AVX and will set the required vcore for this frequency.

I did that and it went to 5ghz on 4 cores lol I can get it stable at around 1.35v for 5ghz without avx but the temps get to around 80 and I wanna make sure I do adaptive voltage. Is 1.35 for 5ghz "safe" dont want to fry my system

The problem you have is these beasts get hot, and an AIO is going to struggle to keep the temps down, 1.35v is not going to hurt your cpu, and 80c is quite normal, what do you run to stress the chip to get to 80c. ?

Oh I understand that

I was using realbench. I dont mind keeping it at 1.35 as long as I know I am not knackering the system haha it runs idle at around 70ish then goes up to 80 when stress testing or via a frostbite game like anthem/bfv

norwegian_imposter · 7 Mar 2019 at 12:35

Yeah I had llc to 6 or 7. definetly not the highest or the lowest either.

Idling at 70c, that is alarming I must say, what are you using to monitor the temps, HWInfo is very good, or Core Temp.

well it might not be 70 idle. I cant remember as I am in work. I will set it properly tonight. If i remember rightly I am a bit concerned my XMP ddr4 memory profile is causing crashes and not my overclock (I think I can clock it lower than 1.35 but I will need to try it again tonight)

I think its more like 60-65 idle but I probably read it wrong haha

oh and HWINFO or HWMonitor and CPU-Z are the tools I have been using.

XMP can cause lots of problems, better off setting things manually. I would look to see what your SA and IO voltages are being set too as well. If I were you I would just set bios defaults F5, then run RealBench again to see what's what.

Have you tried remounting your block, have a look at the TIM spread if you do, see if you have good coverage on the IHS. You did remember to remove the plastic cover from the water block, seen that many times.

hahah yeah I did I may have to order some more themal paste again. Regarding XMP. I am completely lost when it comes to getting my ram speeds up etc.

How should I interpret the realbench stock settings.
