yrelbirb Hi people, i've yet again made some changes on my 2700x overclock

i was 1.32v 4.1 ghz and tried some undervolting

currently i'm down to 1.265v at 4.1 ghz

https://prnt.sc/rpacxu

currently im at a 7 hours of blend test and its still going strong (i know vrm temps are toasty, in gaming its tend to hover around 50 55 degrees though)

can it be expected to hit 4.1 ghz at this voltage?

also i saw that it my vcore drops to 1.248 and sometimes jumped to 1.32. is this an acceptable vdroop? sadly gigabyte board doesn't have any llc option

here's my cpu temps as well;

https://prnt.sc/rpaei6

also; is blend test can be consired a good stability along with my RAM?

my timings goes like this; https://prnt.sc/rpagzr

(not sure about tRAS. some say it should be tCL+tRCD+tRP. some say tCL+tRCD+2. im stable at both values but latency is same. some say it can hurt performance in some cases when tRAS is set to low. no idea on that

deankenny Memory is on 3400mhz now and tighter timings, and seems to be stable so far, 48 hours system uptime with gaming use.



As for case, yes rad is on intake. Bearing in mind I've done all the same testing with side panel off etc with no drastic change.





Those are older pics, i have new exhaust fans and new cables for gpu, but pretty much remains the same.

So for example running 1 quick cinebench yields around 120-150 cpu package power on all the videos or screenshots that I have seen with similar scores to mine whereas my package power hits 186w. I see PE level 2 is one of the most popular options to choose, whereas when I choose this option, even with undervolting, I am 75c+ in temps and using hell alot of power/watts compared to other Level 2 users.

I'm not sure what your system specs are as you don't have a rig sig filled out yet.
I understand your on a Kraken x62 (meh) but what about the rest such as case, fans etc.
Reason I ask is even with my custom loop with a EK monoblock I still run a 120mm (2000 rpm chocked down to 850 rpm normal running) behind the CPU socket.
It will make a difference in which multiplier system chooses during boot, and will also lower CPU temp.


Is Rad setup as intake? I run all three of my rads as intake (2 x 360s plus a 140mm).
How about case interior air flow? Anything to cool VRMs? When not running a tower cooler you remove any/all direct air flow to cool VRMs.
When I ran a FX9590 I HAD to have active cooling on both sides of socket to tame that animal (remember those days @Minotaurtoo hahaha).


I always had real good luck running PE3 with Auto Vcore (Offset + mode) and Auto CPU LLC which always ended up at 42x (4200MHz) @ 1.250v SV12 TFN under load running ITB AVX version.
Imho sounds like you need to work on thermals/airflow.
As for that negative offset to lower temps, it might not be the case here but I have found that sometimes lowering voltage can add heat/strain to system.
For me sometimes adding voltage actually lowered temps, I know it sounds crazy, but you won't know till you've tested it.


What memory kit are you running? Those are way less than optimum timings for 3200MHz. Not able to make suggestions without system info.

Thinking your board may be a bit to aggressive with the boost voltage when using the performance enhancer at that level.

reason for edit: forgot important conditions aka I'm an idiot.
I'm scoring 1902 on R15 now when putting it as real time priority. Reaching 73-74c. Actually think im happy with that even if package power is crazy. Real time scenarios most likely will not be like that of course.

have you tried an all core overclock? With my 2700x I was able to get an all core OC of 4.25ghz at around 1.4v, many could do it for less (vdroop was bad on my board for this chip)... since switching to the 3900x it's been a different world for me, I run out of "safe" voltage room way before power consumption or temps become an issue... I can't even get this chip to pull the same wattage my 2700x did staying within anything reasonable for voltages.

Minotaurtoo not sure what you are expecting out of the chip really... when I had one, I could easily see over 200w power draw to achieve mid 1900's cinebench R15 scores... I'm on a custom loop cooler and I even saw temps hitting in the 70's at that point... I usually ran mine with PBO enabled and a small undervolt then just let it do it's thing. With that I achieved a score of around 1850 and I usually saw power draw around 150w or so and temps in the low 60's then.. I'd be surprised if you could score 1900+ on one of them without having temps hitting at least near 70C... unless you were running an unstable overclock with voltage too low... that being said, I could run benches at significantly lower volts than what was actually stable and make my temps look better than they actually were.

deankenny Having such a hard time with this chip, i've had it since not long after it's release paired with an Asus x470-f gaming board. After early problems, 100% constant fan speed and many other issues I slowly trickled them down, but 1 problem always bugs me and that's my temps and cpu package power vs other peoples 2700x.

On PE level 2, even with an undervolt of -0.1 running a cinebench r15 results in temps of 75c+ and even more worringly cpu package power exceeds 185w, which would explain the high temperature, I'm also running an AIO cooler in the kraken x62, which just makes all this even more frustrating. If I add more undervolt, I don't post, if I default the vcore then the temps are even higher of course. If I set PE level 1 I get some good looking temps of 60c under a cinebench run, but my score goes down to 1700 just under, cpu package power is much lower too at 120-140w. Whenever I see others results, their temps are usually below 70c scoring close to 1900 and cpu package power of around 150w seems to be everyone elses norm. I've been through many bios's and it's always the same.

This video is old now, but still applies today. I'm begging anyone for some help on this, as it's really got to me now.
