@GMart84 @tarfeef101 @Zando Bob @Falkentyne @alatron978 guys sorry to bother you guys, just want to understand one thing, The VRM on my MoBo get's really hot and its actually impossible to touch, you can actually feel the heat... any suggestions on this..

 

PS: currently my MoBo is still not inside a case but on an open bench without any direct airflow towards the VRM. Also I have changed my CPU Core/Cache voltage to 1.255 and it's really stable..

 

Tks & Regards

Just lean a fan on top of them . BTW its fine for vrms to run at 90C for 24/7 use.

Tks Man, Appreciate your quick response. & Big thanks to you..

@Sajeev VRMs tend to get hot when OCing.  If they get too hot they will fail as well.  Are you using manual or offset voltage for the CPU? Or any of the auto settings.  1.255 is high but not out of the world high.  I would get a fan and have it blowing on those VRMs.  I hcurrently have fans blowing on the RAM and the VRM even with the cooling fins on the Gugabyte board.

I am using Manual voltage for CPU Settings, the only thing that is on auto for overclocking is the max cpu capacity (I wanted it to set to 140% but then thought setting it on auto would be ok). My CPU Core/Cache voltage had to be set to 1.29 again as 1.255-1.285 the games were just crashing all the time (Battlefield V, Assassins Creed Origin, Rise of Tomb Raider, GTA V). At 1.29 they seem to work without crashing(Includes BOSD upon launch).

Open HWMonitor and see what your mobo sensors are saying. If any of them are hitting over 80-85C then you should look into better cooling for the VRMs. If not, you should be fine. 75C is usually pretty darn safe (I don't know of any computer components that can't handle that) and that's 167 degrees Fahrenheit, very noticeably hot but still fine for the PC.

1) Many VRM components are rated to 125 degrees and higher. So that's not necessarily a problem. 

But, if you want to cool stuff anyways:
1) Get watercooling and blocks for the VRM. This is basically always not necessary. Don't really recommend unless you have time and money to waste.

2) Just stick it in a case with airflow. 

3) Use a downdraft CPU cooler (one where the fan points down). That helps a lot (but hard to do with powerful CPUs since they don't typically have a lot of thermal dissipation capability)

4) Lower your switching frequency for the VRM. This helps with efficiency, but also means the power is less clean, which can hurt stability. But if you're really concerned you can do that.

 

 

I'd recommend option 2

Tks guys, all problems solved just by pointing a fan towards the VRM's. Temps now pretty neat, Ran Aida64, Prime 95 for over an hour and  and OCCT for over 4 hours and found out that temps were extremely stable on both VRM's (40-45) and CPU Core (65-75). So happy now, couldn't have done it without your support and advises. Tks again a ton. You guys rock.. Getting a Thermaltake View 71 case for this build, and yes I am going to swipe the Graphic card for 2 2080Ti's FE on Custom water loop from my threadripper 2950X build which I have running on stock. I'll put my Radeon VII in threadripper build. Some pics from my last build attached here.

Nice! And yeah, the ASUS VRMs this gen have been pretty meh on the Intel side, AFAIK they'd overheat more since it's a 4 Phase or something (whereas Gigabyte's budget boards are an 11+1, the higher ends are a 12+3 or something crazy IIRC). Also cool to see a fellow RVII owner, how's it treating you? I just got back to using mine, finished the X99 rig I meant to put it in and it's been running like a champ since. It'll OC pretty damn well too if I'm willing to have a jet engine simulator in my case, but I've undervolted it a good bit to lower temps, need to tweak it a bit more when I have the time.

Radeon VII is performing like a charm, has an excellent performance, my friend has a 2080 and it beats it I some games, though temps are a case for this card though, I have undervalued mine to 1.08 (stock was about 1.138 V) to run at 1930MHz with a 1175MHz on Ram, I did a small adjustment on the fan curve to make it run at higher rpm's on temps over 50 degrees, it is working like a charm. I have not tried going above 1930 or 1175 in both cases as it is getting the job done for me. I am waiting for the water block from EK or Alphacool to come out to completely remove the fan noise and push it a little bit higher as it would run lot cooler with custom water looping. I did have some reservation while buying this card but I am happy I bought it. My seller has told me that running this card on a an AMD chipset makes this card perform better(strange).. Waiting for the water block and then will try and see how it performs on an all AMD system.

 

Do let me know how yours perform after all the tweaking.

I've got mine at stock speeds on the core, 1200Mhz RAM, undervolted to .98-1v most of the time, need to tweak it a bit more. Hot Spot doesn't hit over 95C or so though so that's good (it can go to 115C before it throttles, the hot spot is what throttling and the fan speed go off of). I'm only at 1080p though, if I get a higher res monitor in the future I'll OC it a good bit for sure.

[GMart84]

@Sajeev I am happy it is working out for you.  Enjoy the OC and the rig.

Yeah they basically just double the MOSFETs in each stage to give each one a massive amount of power instead of more, weaker phases. 

They claim this helps reduce transient response spikes/dips, but it comes at the cost of worse output ripple. 


They also could still use more phases... Voltage controllers on these boards normally can do up to 8 phases. If they spend a shitton they can get 10 phases too. But even still, say, a 6+2 would be better. And still not sacrifice on transient response because that doesn't need doublers. But they don't seem to care much.

Aha, thanks. I just kinda know they were eh, but not why. What's the transient response? Ripple I assume is just unstable power.

Transient response refers to how a system reacts to change in the desire output (i.e. a VRM being told to change from delivering 150A to 30A).

When people talk about issues with transient response on CPU/GPU VRMs, they usually are talking about overshoot or undershoot of voltage. So, what happens is that when the power being requested drops (such as when a benchmark finishes), the transient response might be a voltage spike (overshoot) or dip (undershoot) while the load change occurs.

Ripple is just how much the voltage fluctuates during normal operation.
