System Temps?

[SparkTheFloof | TTV]

I am using a 6700k @ 4.2Ghz with a H100I GTX Closed Loop Cooler

Motherboard is ROG Ranger Viii it maxed out at Location 1 & 3 72C Location 2 47C other loaction on MB are 30C

CPU
1-4 Cores are around 73C 64C
CPU package has maxed out at 72c

H100I hits around 42c

My GPU is the 1080 ti Strix and it hits 69C

I have not made any changes to my system yet I am Running RealBench Stress, CPU-z and aida64 for the temps.

Just for a base ling currently my CPU has maxed out at 83C and the CPU Voltage is 1.44 on auto. Tests has only run for 12 mins

So I am thinking of 4.4Ghz at 1.30v also would I see the system cooler if the Voltage is lower and stable.

I think that it might even run stable at v1.25. Just try to get it as low as possible.

Two factors affect the CPU temperature - clock speed and voltage with voltage being the biggest factor, so yes 4.4ghz @1.3v would be cooler. Once you go past ~1.4v vcore, temperatures almost exponentially increase in relation to voltag. Since your MB and CPU are over voting so much on auto settings, I recommend you change voltage to manual for all your testing. After you find your best OC, then you can try adaptive voltage settings.

Update

I tried enabeling XMP, I set the Multiplayer to 44 (4.4Ghz) and the voltage to 1.30 This failed to POST, I diabled XMP and raised the voltage to 1.35. Windows has started not stressing

[Kaihekoa]

Test one thing at a time. You should have already set your RAM to XMP, but make sure your RAM works as specified by leaving the multiplier at default and stress testing the RAM. If RAM is fine, then you can experiment with the CPU overclock.

Also, what is your PSU? If its mediocre that will affect your overclock and voltages.

XMP Issue
Before I complete the Overclock I treid to use XMP and it was failing to post.
I think without XMP my RAM would be faster due to the CAS code.
Without XMP 2166mhz 15-15-15-36 With XMP 3200 (Failed) 16-18-18-38

OverClock
Before Overclock
Stock 4.2Ghz at 1.44v Temp after RealBench were 84c Max and 77c Avarage

After Overclock
4.4Ghz seems to be stable at 1.25v
2x 1 hour RealBench test the temp were 72c Max and 66c avarage
6 Hour of Aida64 (CPU, FPU, Cache and Memory) temp Max 73c and Avarage 58c-65c

Completed 4 Game benchmarks and perfomance did increase around 5% on TimeSpy 2x and Firestike 2x

Is Adaptive Voltage set correctly?

Off set Mode +
Additinal Turbo Mode CPU Core Voltage 1.25
Offset Voltage Auto

CPU-Z shows the Voltage Maxed at 1.30v

Raise VCCIO and VCCSA to enable XMP Profile. How much, there's no answer. You have to gradually raise these until they pass memtest. Maximum recommended is 1.25V for VCCIO and 1.35V for VCCSA.

Tried XMP again with voltage changes and still nothing.

Tried a few games today at 4.4Ghz 1.25v and notice a buzzing sound when at high fps then lowing the fps to 30 it would not be there. Setting the CPU back to 4.2Ghz 1.25v the buzzing was gone at high fps.

During game benchmarks at 4.4Ghz the Min FPS would drop down to like 10 to 50 ever few tests but at 4.2Ghz the FPS would stick at 114+

When the test did complete I only saw a 3FPS gain :D

Tests at 4.4Ghz
Rainbow 6 Siege Ultra 1440P (+3 Fps)
Resident Evil 6 Benchmarks 1440P (500+ Score 25300)
Mass Effect Andromida Ultra 1440P (+5 Fps)
3dMark was a 5% gain on CPU tests

Temps for
4.4Ghz, 4.2Ghz at 1.25v were 72c (RealBench and Aida64 2 Hour)
1080Ti Strix OC never hits above 70

VCCIO and VCCSA is not DRAM Voltage. If you changed DRAM Voltage or Core Voltage they are not the same. There's no fix rule to VCCIO and VCCSA voltage, higher does not mean better. You need to gradually raise them until stable.

Probably coil whine from your PSU or GPU.

I have a different motherboard and CPU but I had issues with XMP when I tried it on mine years ago. it booted but for some reason cause my CPUs temps to rise. I suspect the Ram was getting too hot and affecting my CPUs Air cooler that is directly above with a cm or so gap. I disabled XMP and just change my DRAM clock speed to the same that XMP did but without changing any other setting, no issues, temps are fine and 0 crashes in approx 3 years.

Not sure if that will help as your Ram OC using XMP is higher than mine. Mine was 1600 OC to 2133.

If XMP isn't working at the speeds you paid for, I would RMA the memory after making sure it wasn't anything wrong on your end. What power supply do you have? If it's a low quality one, it could cause all manner of issues. Also, alot of the DRR4 3200mhz needs 1.35v on the memory to operate at those speeds. Make sure the VDIMM is set to that when you enable XMP.

[SparkTheFloof | TTV]

I don't thinking it would be my PSU it's a RM850x

I have been reading up about XMP with Z170 motherboard and some stick seem to be hit and miss at 3200mhz. To fix this they was changing the clock and command rate for it to become stable.

Have you tried tweaking VCCIO and VCCSA? They are separate from VDIMM.
