" rel="nofollow - Hey guys! I tried to OC my R7 to 3750 MHz at 1,35 V, but when I log in to Windows, Task Manager > Performance shows only 1,35 GHz. I tried to reset BIOS to default (both in BIOS and with a jumper), but it did not help. I would expect that it won't boot or something, but not that 1,35 GHz suprise. https://imgur.com/a/IeiGc Funny thing, when I go with 3700 MHz, even with the lower voltage, it is OC'd and Windows shows ~3,7 GHz. Do you have any idea what is going on? I would appreciate any feedback. Thanks, KLU -------------

" rel="nofollow - Are you sure you are not just seeing your idle frequencies there? Your screen shot shows only 7% CPU usage which will typically mean you are in a power saving mode. When your CPU usage is low the system will lower voltage and frequency to save power while providing enough performance for the tasks currently running. As the usage goes up so will the frequency then voltage up to it's full speed when needed. If however you are locked at that frequency even under high loads then there is something wrong. If that is the case then clear CMOS with the jumper on the board and pull the battery for an hour or so. Remember to disconnect the power cord while the battery is out or it won't work. -------------

I've heard of 1,5GHz and 2,2GHz bugs but 1,35GHz is a new one to me. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

" rel="nofollow - Now peeked through your screenshot. Holly cow, is that 329Mbps Internet speed? If you're clocking with P-states you can put your idle speeds wherever you want them. I think for regular idle you should get 2,2GHz, though. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

Looks like you're idling. Put a load on the CPU (Maybe CPU-Z stress test button) and see where it goes from there. If clock speeds increases, then you're fine. ------------- MB: X399 Taichi, UEFI L3.32 VGA: EVGA 1080 Ti FTW3 PSU: Seasonic PRIME 1300 W PLATINUM CPU: AMD Ryzen Threadripper 2950X MEM: 4x16GB, 3600MHz G.Skill Trident Z F4-3600C17Q-64GTZKW |

Hey guys! Thanks a lot for your posts. However, I reset the BIOS by removing the battery (for about 40 minutes) and changing the jumper. Then I set 3750 MHz with 1.35V and nothing changed. I do not use P-states or anything, I'm just changing the CPU freq, fixed voltage and that's it. Everything else is on Auto (-after clearing CMOS). I tried to change CPU Load-line calibration and VDDCR_SOC to Level 2, but it makes no difference. Note: The speed does not increase (I ran prime95). Here's how it looks like under load: https://imgur.com/a/dpyZs" rel="nofollow - https://imgur.com/a/dpyZs Note 2: When I set it to 3700 MHz at any reasonable voltage, it is OK (it works with 1.35V and 1.30V too...). It looks like this: https://imgur.com/a/wvJvO" rel="nofollow - https://imgur.com/a/wvJvO Everything above 3700 MHz does NOT work (boots with 1.35GHz). 3725MHz or higher does not work (on 1.35V, but I expect it won't work on any higher voltage either). It is strange, because it was working before (I could OC to 3,79GHz, as you even have it confirmed on the CPU-Z validation link below). I even thought for a second that it could be related to recently discovered CPU flaws (Meltdown & Spectre) and maybe Windows released an update or something, but yeah, I know.. it would be strange. Any further thoughts will be much appreciated. PS. zlobster, yeah... I have symmetrical 1Gbps :) I must have been downloading something  KLU -------------

overclock on p-states, its much stable and it always works the way u put it there |

Not before we see your complete system configuration, PC components and peripherals, software & firmware versions, etc. P.S. effin nice Internet speed there!  ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

" rel="nofollow - Did you update the UEFI recently? There have been bugs with some of the newer AGESA revisions that caused issues with overclocking on certain configs. I am still on v3.0 on my Taichi because it's stable for me and 3.2 was not able to OC my CPU as high as 3.0. I may try the latest update at some point but my system is stable at 3.9ghz at 1.3v so I don't feel the need. -------------

" rel="nofollow - I'm currently on P3.30. That 3,79 GHz OC was done on it too, I think. I'm not 100% sure, tho. Maybe I could flash it again, to P3.20 version for example? What do you think? Here's HWInfo report: https://justpaste.it/1fj4x Thanks! -------------

That CPU usage graph looks strange. It says 1.35GHz but your CPUs are loading only about 35%. 1.35 / 3.75 =0.36, so I feel I'm onto something. Try using a different CPU monitoring program like HWINFO64 to see what your CPU is really doing. I wouldn't trust task manager from that picture, at all. A full CPU load like P95 should not only load each core to 35%. Use HWINFO64 with sensors window open and the previous "bugged" 1.35GHz settings and report back.

So, I set it again to 3750MHz and 1.35V and here are the screenshots: Idle: https://imgur.com/a/QTBT5" rel="nofollow - https://imgur.com/a/QTBT5 Stress (P95): https://imgur.com/a/58BpS" rel="nofollow - https://imgur.com/a/58BpS -------------

Holy sh*t, man! You're a hero! I'm leaving the settings for future reference. I bet I won't be the only one facing this bug: 1. The settings in OC Tweaker are set to Auto, except I only changed CPU LLC and VDDCR_SOC LLC to Level 3. 2. I disabled C6 Mode, Cool 'n' Quiet, C-State Control, Core Performance Boost. 3. I set P-State 0 (FID=96 - 3750 MHz, DID=8 and VID=20 - 1,35 V). Voaila! https://www.imgur.com/a/Fg7Rt THANK YOU ALL! -------------

I had the same problem, solved by overcloking with offsets instead of fixed voltage. Try setting your processor to default voltage (1.18750) and then add via core voltage (offset).

This is definitely the solution. Ran into this with my new X370 Killer SLI and R5 1600 setup for an HTPC. Didn't have this problem on my X370 Fatality K4 board and R7 1700 setup though. Also, anyone else notice in Windows task manager the CPU clockspeed does not stay constant at whatever you set even with variable options turned off? I have my 1700 set to 3.85GHz and it varies up and down from 3.5ish to the set 3.85GHz. Same with the 1600 chip. There's no fixed clockspeed setting. I have windows set to High Performance mode not balanced, and also in the BIOS have all states turned off. |
