New i9 9900k Rift in VR

[dburne]

Sorry, I forgot to update my mobo in my sig. I have the Asus ROG Strix E-Gaming. I am also surprised at my cooler. I was this close to getting a newer cooler but so far so good. On a stress test I got up to 80 degrees, but it still passed. What's your definition of "way too hot"?

 

When I upped the voltage to try and get to 5.2 my cores were breaking 90c.

However on adaptive it gives more voltage under load than set in bios also, but I like adaptive as my voltage drops when not under load.

At my 5.1 overclock they hardly break 70c.

Good rig, I'd really wouldn't use 1.425V with those chips. If you're one of those people flying every day or every second day after work and hours on the weekend I would not go over 1.3875 or 1.4V if you don't want chip degradation and buy a new one in just a year or so.

Ok, thanks for the tip. I fly a few days a week. I can't spend all day in VR. :) I have Adaptive mode on in my OC settings so that way that voltage isn't always that high. When flying, I put my computer power options to High Performance, however, any other time it's on Power Saver mode that way the clocks and volts aren't constantly high. I just installed it and still testing out the limits though.

I dunno, I've never seen anyone burn out an actual CPU by OCing it...

 

 

Its possible IMO, just not likely.

When this is working as intended you shouldn't have any worries about needing a new chip soon, no degradation.

The heat isn't as much of a problem as the voltage. If the CPU gets too hot it will just throttle and protect itself. If you have a voltage just below the crashing threshold but still high (which is subjective what that means and differ from chip to chip of course) then your chip still is degrading even if it never crashes (stable) or never runs too hot. This is "killing me softly". This of course only happens if you push the chip to its limits in terms of applications, degradation in a case of using paint 24/7 is unlikely.

Not sure if it's the high speed, the newer chip, or both in combination, but the flight I had, although ended too soon, was buttery smooth. Before, I would've had plenty of stutters in that time frame.

Agreed the 9900k is a very sweet chip, I get great performance with it.

I set in Nvidia Control Panel is "Prefer Maximum Performance" for the DCS profile.

 

don’t the nvidia cards run at “maximum performance” speeds when there is a load on them and work to do?

[Tallguy]

After some stress tests, I have it stable @5.2GHz & 1.425v right now

 

Whut? :huh: I have a 9700k running at 5.1 @1,248v. Why is your voltage that high?

[dburne]

There will be more fluctuations in GPU speed with the default setting of "Optimal" as it continually tries to adjust depending on the amount of load on it.

9900K has 16 threads, yours has 8 threads. So "double" the "power".

Not quite, since HT isn't helpfull in DCS to be used, but apart from this: most 9900K OC'ers report running at about 1,35v, even lower!

So...saying dat double the threads require that much more voltage isn't correct.

I used this guide from Asus to help overclock it. Again, I'm still testing, but I haven't tested lower voltage yet.

 

[dburne]

You definitely should. Lower voltage a little at a time stress testing in between for heat/stability. I use Intel Extreme Tuning Utility for the stressing. I kept going until it would not pass a run, then upped the vcore back up a notch or two from there.

But 5.2 is going to require some voltage for sure. More than I was comfortable with on my chip which is why I settled for 5.1.

Did I say this is the only thing pulling more voltage or did you interpret my statement this way? And is saying: "Hyperthreading does not pull any voltage at all" correct? No, it isn't.

Hyperthreading doesn't really count as threads... At least not "double the power"

sure. but if there is no load, there is nothing to do.

 

it would be like driving around town with your throttle foot continuously pressed to the floor. lots of rpm, but no work to do.

GPU still downclocks with no or little load.

It is just more consistent at max clock with "Prefer Maximum Performance".

Remember I set in an Nvidia Profile for the game. And it downclocks there as well, when like at just the hangar.

Yup this... Double check it with MSI afterburner or any other utility, and when you are in desktop mode, you should see the clock/temp/etc go to "normal".

[etherbattx]

fair enough.

 

other than the data stats in AB, do you notice it in game?

 

i haven’t seen any difference in fps rates or stutter.

[pimp]

So I lowered my voltage to 1.35v & kept 5.2 clock speed and ran another stress test and it passed. The max temp was 87C which is weird, because yesterday, when the voltage was higher, the max temp showed 80C. So I'll keep testing. FYI, I used ROG RealBench & Cinebench for testing.

Are you running a fixed voltage or adaptive?

Adaptive.

[dburne]

Adaptive.

 

Better keep an eye on max voltage under load it is applying - but then I have a diff brand MB so that may play into it.

Wilco. Thanks for the tip.

Yes I interpreted it that way.

True, HT is requesting a bit more voltage, but not double.
