" rel="nofollow - Hi everyone. New here. Please be kind. I am having trouble with my x370 Killer SLI. RAM is Corsair Vengeance LPX 3000mhz. It seems I can overclock the CPU ( 1600) no problem IF I leave RAM at default ( 2133mhz). But I hit a wall of 3.7ghz with RAM at 2800mhz. I can get 3.9 with modest (fixed) voltage with RAM at 2133. But if I try for such overclocks and so much as touch the ram it won't get into Windows and just continually reboots. I have newest BIOS and Windows is updated. Can anyone assist with this RAM issue? How do you even adjust timings? On the OCtweaking page of bios, it will only "load xmp" profiles, and ignores changes in timing value. On the other page called "ram overclocking" or something similar, I'm not sure what to make of it. What would a value of 1400mhz represent? How do I change timings if this is the issue? How do I overclock the CPU and use faster memory speed? Thank you.

Ok scratch my comment about the ram overclocking page. It's speaking in double data rate language. 1500mhz is 3000 mhz. This is the page to tweak timings. Not that this helps me. The same behaviour is displayed. In fact my PC jsut failed to boot at 2800mhz ram...loaded into Windows, looked at CPUZ and it's 2133! This platform is not ready man. It's so immature and flaky. I am getting absolutely astonishingly awful Realbench scores and overclocking is really tricky. I need to learn how to do Pstate overclocking and I don't understand why cpu clock speed and ram speed interfere with each other.

Try 2933 or 3066. 3000 gives Ryzen heartburn. |

I understand that. In fact 2933 is the only closest speed available. But it just boot loops if I select 2933 and save. I had 2800 but lost it being stable somehow ( every attempt at 2800 is a boot loop now). The weirdest part for me is I cant over clock the CPU and have Ram anywhere near it's rated speed. It's like as soon as I try overclocking, the flaky ass memory controller throws a fit.

I still haven't seen a request for the mem Kit P/N. Please go to the below link and install the Freeware version of Thaiphoon Burner. Then post here the capture generated from the Read function. http://www.softnology.biz/files.html" rel="nofollow - http://www.softnology.biz/files.html |

Got it!! At least the RAM instability /clock speed issue. I changed procODT to 48. With this change I got 2933! Now I need to learn how to do Pstate overclocking. I really don't understand it but all I know is I dont want to run my CPU at a fixed voltage.

Now change to my recommended procODT of 53.3 if you haven't yet. Going "lower' on the procODT value is defeating what you are attempting to do there. Lover values entered there only serve to further limit the mem. ie: akin to lowering CAS/CL |

Clarification As in lowering CL will lower your odds at attaining to obtain their rated speed. |

way ahead of ya XD. Learned 53.3 is default and AMD recommends 50-60 so I had already gone ahead and did that. Thank you very much for commenting. Now...are you able to lend a hand with overclocking? I know my 1600 can do 3.8 at 1.35v. I would like to use Pstate overclocking. What is the process? Do I use off set vcore? if so, do I take default vcore ( something like 1.24v) and enter a offset that would make it 1.35v total? What about the Pstates page? My tries at overclocking left me wondering why clock speed stays at max and never goes down at idle ( which I believe is where Pstates come in? Thank you Wardog.

" rel="nofollow - DB Have you tried bumping SoC just a pinch to 1.1 or 1.175, DRAM Voltage up an additional +0.025 to 1.375, procODT to 53.3, and surely MEM_VTT to 0.690 or maybe even 0.700 yet? That advice there of mine has helped many Users. That knowledge is gleaned from days and days of mem testing here the 6 Kits of DDR4 I have. Also, consider that a "starting point". You may very well want to lower those v's as testing there shows/allows for.. |

" rel="nofollow - Yes, I have come across that info. SOC is at 1.1. As far as Dram voltage, I (believe?) my RAM instability /unwillingness to clock at 2933 was due to procODT as 1.35 seems to be fine.
VTT is half of Dram voltage automatically. Not sure what benefit raising that offers? I know NOTHING about VTT though.

p=state OC'ing is hampered in BIOSes containing AGESA 1.0.0.6. It's not th AGESA yet rather the internals of BIOSes that have .6. That's the reference point I'm using. Tonight ASRock is beginning to release new BIOSes with AGESA 1.0.0.6a. When 3.00 is released ror your board, remember FIRST to Reset to UEFI Deaults, Save and Exit, THEN and ONLY then flash as this is major BIOS re-write/update. |

" rel="nofollow - Ugh. Why is it sitting at 1500mhz? I have 1.36v atm with level 3 LLC ( 1.35vcore in bios), and 3800mhz is set in bios.... Coolnquiet is off, global cstates are off. What the heck causes this?

I've NEVER seen mem on Ryzen post at an actual 1500. |

I meant CPU clock speed. was a 1500mhz. Solved by using offset vcore ( a reply on reddit told me there is a bug with using fixed vcore and offset fixes it. I scored like....420 in Cinebench CPU test with this "bug". Even with out this "bug" I havnt solved miserable benchmark scores. at 3.8ghz and 2900mhz ram I'm scoring 90,000 system score in Realbench. 1255 Cinebench CPU score. I just don't get it lol.

Also, totally incorrect sensor readings. example: Realbench shows 20. some odd for "CPU usage" and zero for temperature. HWinfo64 shows 0.994 for VID, etc. A lot of incorrect numbers on a lot of software. I still say Ryzen wasn't ready.

Make damn sure you are using the latest versions available of monitoring apps. Many had issue with proper reporting concerning Ryzen in previous revisions. Too. ONLY use one monitoring app at a time. The chip responsible does NOT at all like more than one app accessing it. Been that way for decades now. |

" rel="nofollow - Well, 3.9ghz "stable" ( can't 100% confirm yet but appears so) @ 1.375v. I am watching https://www.youtube.com/watch?v=52Tw-wcT7o4 For Pstate overclocking as well as trying to understand https://hardforum.com/threads/ryzen-pstate-overclocking-method-calculation-and-calculator.1928648/ 's spread sheet. The Hardcopy guide is easy to follow but then loses me at Vcore. "Change your offset voltage by adding or subtracting" adding or subtracting....what? Also, this article contradicts the video. In the video he says put it all on auto, and then you go input numbers for Pstate which will controll Vcore I presume. The article says to " change your offset" ( in a very vague manner I might add) and shows pictures doing it. So, A little confused. My default vcore is 1.2375. so offset would be + 0.14. But do I leave vcore on auto...or use offset? Contradicting info dang it. I tried following the video. at idle, CPU is at 1500mhz, doesnt change under load ( this is bthe bug again with using fixed vcore)and vcore is at a static 1.375...so much for Pstates. Also there is no option for minimum proc frequency in the AMD balanced power plan. Edit: I learn AMD disables Pstates when you overclock. WTF is this? No really....WTF is this? That's absurd. |

OK scratch that, all is well, sorted it out. 1.375v, 3900mhz for load, dropping to between 1.225 and 1.237 and 1500mhz to 2400mhz-ish across the cores now as I type this. I followed https://linustechtips.com/main/topic/769094-guide-to-p-state-variable-frequency-overclocking-on-the-crosshair-vi-hero/" rel="nofollow - https://linustechtips.com/main/topic/769094-guide-to-p-state-variable-frequency-overclocking-on-the-crosshair-vi-hero/ and ONLY set Psate zero., went back to OCTweak page and set my offset vcore. Booted back into windows and AMD power plan had the option to set min proc frequency. I've now done everything I wanted to do with this chip and board! Naturally I wonder if it can do 4ghz but I don't see a point. It will bring with it a need for a lot more vcore and heat. Thank you again Wardog.

Same here. I cant get stable 3.9 because mbo has big v drop. If i start playing with load line calibration multiplier get stuck at 15.5 (1547MHz). Asrock fix this please. I found a lot of buggs on this MBO.

LLC should not be causing any sort of multiplier bug... I have a killer SLI and don't experience this. I use level 1 for SOC and 2 for CPU. The only reason I havnt gone for 3.9ghz is I hesitate as it needs 1.37v or more ( not 100% sure) and only 1.3v for 3.8ghz. I don't think it matters and 3.8 is so easy to attain.
What does cause a multiplier bug is using fixed Vcore.
