overclockimg Overclocking help on 7820x

[JERKSON]

About a month and a half ago I completed my second ever build, and shes pretty sweet. I'm using an Asus Strix X299-e with an i7 7820x, being cooled by a Corsair h150i 360mm AIO in push pull, and 32 GB of Corsair Vengence 2666 DDR4. When i got everything up and running my first instinct was to turn on XMP and dial in a modest overclock. I could get to around 4.4 ghz at 1.25 volts with XMP on, but never more than that. After reading on the forums that my CPU should be able to hit 4.7 with that voltage, i began playing around. I even got my voltage north of 1.3 and couldn't make 4.7 stick. Eventually with XMP off I hit 4.9 at 1.25 volts! with peak temps in the 90s but averaging the mid 80s. So I decided to turn XMP back on, and had the same stability issues. I decided to manually enter the XMP numbers with no change in stability. After turning all the timing controls and voltage back to AUTO, and just setting the speed to 2666 mhz I got the stability i desire but temps are hitting the 100's and thermal throttling. I am aware that the memory controller is on the chip, but I don't know what to do from here, do I keep the faster ram? Lower the CPU overclock? Is there some fix that i havent tried? maybe manually set the Dram voltage to 1.2 instead of Auto? Thanks so much for reading, any reply would be helpful.

I know it sounds sketchy, but delidding on x299 is almost required if you want to keep temps down. I would say a more modest overclock would be better for now, maybe something like 4.5 @1.2v. Memory and clock speed are fairly important, but if you can hit that kind of clock speed at only 1.25v then you might have a golden chip. It would be really cool to see it delidded.

can i ask what in the world you need 8 core's at 4.7ghz for?

Need?  I personally prefer my 8 cores at 4.8GHz.

so you are just shorting the lifespan of your hardware, increasing heat output and increasing your electricity bill because you prefer it that way?

Haha...This chip will last longer than I want it, and I think I can spare the change for the electricity required to keep the room cool and the machine running.

look, if you want to do that fine, i'm not going to stop you. but to me overclocking is like, if i don't need it i won't do it.

That's cool.  To me not overclocking is leaving free(cheap) performance on the table.

that is true, but the instability that it can cause as well is not worth it to me. but i almost never turn my machine off, i just leave it in hibernation, so if it were to crash i'd lose a bunch of stuff...

You do you.

 

But, maybe don't jump into a thread with a poster asking about help with their OC and ask them why they are overclocking?

i always ask because tbh i always give the advice of if you don't need it don't do it...

So, are the troubles I'm having with dram normal? And I am planning on deliding I just wanted to see if everything was kinda normal.

I intern at a computer simulation lab, through my school and the extra cores really help with that. But I am a gamer at heart, and since the 7820x can lag 10-20 fps behind something like an 8700k the clock speed also helps to close that gap. Also overclocking is just a cool hobby.

It seems fairly normal, since you're stressing the imc more with the memory oc it will cause the chip to run hotter. See if you can get 5ghz on that puppy after a delid and some conductonaut.

Heck yeah! I'll order a deliding tool tonight, have any recommendations?

This.  This is so true.  Playing the overclocking game is something I do and completely skip the actual games.  Chasing benchmark scores is fun.  I currently hold the highest scores in Fire Strike and Time Spy for a 2700X and single 1070ti configuration.  That means absolutely nothing, but it was hours of fun chasing and achieving.

Rockitcool makes good delid kits for a decent price and it's what the almighty steve from gamers nexus uses so i figure it will work pretty well

Yep, that's me, I feel kinda bad because I really don't even play games that much anymore, I just LOVE looking at how far I can push games and synthetics. I need to get back into gaming, just been way too obsessed with benchmarking as of late.

Someday I really hope to break a record, someday, I will get there.

Well if you haven't seen yet -- Destiny 2 is free on the Blizzard.net app.

Really!? gotta go check that out RN!

Hey! I had the same issue with heat before delid, and I would absolutely recommend replacing the crappy paste Intel have chosen with the Grizzly Conductonaut! I can easily overclock to 4,8 now with max temps under 70-75.

 

I even got 5 GHz and under 75c stable, but that was with Conductonaut LM between AIO and IHS, something I really regret and will not recommend doing  

I use the NZXT Kraken x62 and used the rockit 99 tool and nail polish to seal the micro components on the board. 

 

The reason I ned the extra boost is because of X-plane 11, DCS and P3DV4 VR. The extra MHz helped a lot on the performance!

 

Good luck!  And don't forget to leave a small space when gluing it back on, it's obviously for ventilation. Look at picture
