I've just built a 7600K system and am getting some confusing monitoring information and was wondering if anybody could offer some clarification on some temperature concerns.

First attempt was with a Gigabyte ZA270X-Gaming K5 and Thermalright Le Grand Macho RT. No extensive messing around with settings, just using the built in profiles. Could not reliably get 4.6GHz to work, but stable at 4.4GHz with poor temps at over 80c load in HWInfo (and various other temperature monitoring tools). Second 7600K, second Gaming K5 and Noctua DH-15S, overclock profile of 4.6GHz stable and temps comfortably below 80c load. I was reasonably happy with this speed/temperature balance but for various issues I've had to change from the Gigabyte board.

Now I have an Asus TUF Mark 1. Not played with this much so far, but have tested with auto tuning at 4.5GHz and this appears stable. However, HWInfo is already reporting core temps spiking up to around 80c. In Asus' AI Suite 3 temps are being reported as being approx 15c lower and as such, the fans aren't spinning up as expected - the Gigabyte was aggressively spinning up all the time. Before I attempt to push this further, back to the 4.6GHz I was happy to settle with, which temperature reading should I be trusting or worrying about? I've read that Asus monitors and reports from the socket rather than the cores themselves and HWInfo does have a line that corresponds to the temperature reported in AI Suite, but this is very different to the line(s) that other people seem to be reporting/basing their temperatures on.

Firstly I would suggest ditching the profiles as they in best case only overshoot everything....like msi 1 button 5.0 GHz one putting the CPU at 1.5v.
Secondly go trough @Jpmboy signature overclocking guide (asus website)...
For temps, go with Core Temp or Hwinfo...ai suite is really for automated / beginner stuff.. for anything more you ditch ai suite / key bot and other software like that...
Also if the difference in temps keeps on going try and check your PLL voltage in Bios...A value of 1.1 - 1.2 should be fine...
Report back once you do this and will see where to go from there. What freq is your ram at ? XMP ON ? Try putting XMP off and set freq manually.

Hope it helps..

If you want a 5.1/5.2 (delidded) chip cheaper than Silicon lottery, LMK. smile.gif

Got a potato 7700k L701D055 (VID 1.296) today.
l0KhlOA.jpg

~1.305V for 4.8GHz, VID 1.296. Couldn't scale any further without a delid (probably 1.35x-1.36 for 4.9.

My 6700k L548B994 (VID 1.168) does 4.8 1.412 delidded with some further scaling potential though a core fails anything AVX beyond 4.5GHz
Though I'm running multicore acceleration ratios 50-50-48-48 stable with speedshift as a daily driver.

Feels like a downgrade, and its not exactly rock stable at that voltage yet.

I've delidded my 7700k and placed CLU under the IHS. I'm using Arctic Silver 5 under my water block. I've got 480 worth of rad (2x240) for my CPU and GPU. I'm running at 5GHz @ 1.33 adaptive voltage. I'm using the 3200 XMP profile for my RAM. I set IA AC Load Line and IA DC Load Line to 0.01. Everything else is set to Auto.

When running RealBench I get up to mid to high 80s in temps, and when gaming I've even seen it peak at 90C very infrequently. I tried reapplying the CLU which looked like it was a bit clumpy after I re-removed the IHS and it also seemed a bit light, so next time I applied a little more and this time it came out more liquid. First time I had used some RTV to glue the IHS down but this time it's just held in place by the motherboard bracket. Obviously I replaced the AS5 while doing this as well. Temps are basically the same as the first time. Just to prove that I didn't completely screw up my loop, my GPU maxes out around 45-50-ish (I don't keep much of an eye on it honestly, since it stays so cool) when under load. I also just quickly tried backing down to 4.9GHz 1.28v and the temps barely changed either.

Before delidding I couldn't even last 30 seconds stress testing the CPU at 5GHz 1.3v because it would thermal throttle at 100C almost immediately, so there definitely was an improvement from the delid. I've even managed to get a possibly stable 5.1GHz 1.35v but really didn't like the temps since they got a little over 90C in stress testing.

Some SS of bios and stress test with HWMonitor running:





Well the good news is I might have figured out what my problem is. Based on a random comment elsewhere about making sure that your microchannels are perpendicular to the jet plane, I realized I hadn't considered that to even be something to worry about. So I checked my water block and what do you know, I have it parallel instead of perpendicular. Thankfully I had clear liquid and could tell the problem without pulling things apart.

I feel like a dolt for running it wrong like that for a little over a month now. So looks like I'm dismantling my loop again tonight to fix it. Really hoping this gets my temps more under control.

I'll run it on air to get everything squared away, then delid/water.

Ran first "something", clean install so I don't have any CPU benches loaded. Wanted to see if my vid card was operational before putting the water block on it, so I ran TimeSpy and Fire Strike. CPU boosting to 4.5@ 1.28v, top temp 68C w/NH-D14 and whatever stock fan curve the bios applied, this is all still stock bios settings so Asus auto rules on the voltages. Never thought to look at the reported idle voltage in bios, these readings were HWinfo64 based.

Edit: 1.168v shown on the same bios screen encrypted11 shows in #2045

I believe in that case your Vdroop should be measuring the difference between Vcore and VID?

Anyhow, the reason I ended up not using DVID mode is because I noticed it would give my chip a LOT more volts than necessary. Like easily 0.1v more than needed. Doing an offset of -0.1v can be risky because at lower speeds you could then BSOD. So yes I ended up returning my board just so I could get one with Adaptive mode. I never would've thought that would be an issue given I used offset mode on my Gigabyte X58A board (back before adaptive existed). I think I just got pickier because there are other better options out there.
My Gigabyte does not have Vdroop at the Vcore.

Example with all power saving features off Auto LLC, DVID/Adaptive full load prime95 1.332v, RealBench 1.284v, IDLE ~1.296v. No Vdroop.

Also DIVD at -0.1v is not risky because it only lowers the turbo Voltage, idle voltage is not effected I checked.

Yeah I run 1.3 for 4.8ghz also. It's not great frown.gif

That sucks man!
Love to see the chip in the OC chart though. Could post the required info for it?
