I can set fclk but uclk will be dropped. it says if I leave fclk auto it will be = to uclk but still drops to 2:1 above 3600mhz mem freq.

KaRtA Posted January 6, 2020 Share Posted January 6, 2020 It should work if you set fclk = to mem clock , so 1600fclk to 3200mem alternatively, there is a setting in the AMD menus to fix FCLK/UCLK 1:1. I think if training isn’t correct it will reduce UCLK to aid. 1 Quote Link to comment Share on other sites More sharing options...

Will try this fclk to mem thing. amd cbs menu nbio settings, xfr enchancement fix is done. but its ineffective Quote Link to comment Share on other sites More sharing options...

flanker Posted January 6, 2020 Share Posted January 6, 2020 (edited) depends on luck, still 1833 something like cl12 is fine for tests Last time, I tested effectivity on daily cooling, I beat my previosu record and I had -100 MHz on CPU than before. https://hwbot.org/submission/4306628_flanker_cinebench___r15_ryzen_9_3900x_3492_cb Edited January 6, 2020 by flanker Quote Link to comment Share on other sites More sharing options...

flanker Posted January 7, 2020 Share Posted January 7, 2020 yes, it helps me in Cinebench. Of course, Im a little lazzy last months to test more :D. But I believe, next week I could test more with RAMs, some SUperpi and imporve my results in Cinebenchs and Geekbench. Quote Link to comment Share on other sites More sharing options...
SparkysAdventure Posted January 8, 2020 Share Posted January 8, 2020 Apparently someone got 1933 ratio fclk working on their chip. Can anybody else get it working? Quote Link to comment Share on other sites More sharing options...

Its heavily cpu dependant, I think. I did not even reach 1866 to boot on this 3800x. tried vddg up to 1.175- soc 1.2 - but cldo vddp was auto. aida benches are not that strong, with a good eff I think read should be well over 60k, as well as copy. 1 Quote Link to comment Share on other sites More sharing options...
SparkysAdventure Posted January 8, 2020 Share Posted January 8, 2020 I thought that 2:1 was forced above 1900. Did something change in a recent bios revision? Or was the 1900 limit never the case? Quote Link to comment Share on other sites More sharing options...

But I can't get it booting above 1900 fclk set in bios. Quote Link to comment Share on other sites More sharing options...
mahaudi Posted February 28, 2020 Share Posted February 28, 2020 (edited) This is always referred to as VDDG Voltage, but which VDDG Valtage now? In my Impact Bios there are two VDDG voltages VDDG CCD Voltage and VDDG IOD Voltage What is CLDO VDDP Voltage ?

Before they were linked, now you can try to lower iod and keep ccd at same voltage as before and see if you can run higher fclk cb free.

mahaudi Posted February 28, 2020 Share Posted February 28, 2020 Every time under LN2 after a reboot I have to heat the pot to -88 ° c so that the system can boot up again. Is there a setting that circumvents this ? Some can boot again at -170 ° c Quote Link to comment Share on other sites More sharing options...

Is there a setting that circumvents this ? Some can boot again at -170 ° c I'm unsure as I've never used x570 on Asus but in my testing if a cpu can full pot, it should be able to reboot at full pot and not cbb if your settings are correct, crash or not. The only time I see a cbb is when I try to change fuclk when full pot, and on some cpu's changing memory clock, albeit rarely.

mahaudi Posted February 28, 2020 Share Posted February 28, 2020 So does VDDG 1.15v in the LN2 Guide mean the VDDG CCD Voltage? My CPU does full pot but every time must be heat @ -88°c get reset/reboot Quote Link to comment Share on other sites More sharing options...

Broken APEX49 Posted April 23, 2020 Share Posted April 23, 2020 (edited) Buy Impact and Ryzen 5 3500 Cooling is AIO air conditioner. Set to LN2 mode for memory lockup. I want to prevent the CPU temperature from rising extremely. Which part of voltage should be adjusted? Which is the best BIOS? Please professor.

IvanCupa Posted June 13, 2020 Share Posted June 13, 2020 (edited) Hi, I just have time to mess with this Zen2 & C8I & C7H again when my TridentZ Neo arrived. But I have strange issue, have 2 CPUs that can run FCLK 1900 (one at just 1.1vSOC) validated on X570 Godlike & low end board MSI B450 VDH+, passed memtest flawlessly (DDR4-3800 at 1900 FCLK 1:1 UCLK). Back in Asus board I happen 1866 FCLK wall. At best I boot & see Windows logo start up and then keep rebooting. The other CPU just not pass POST at all (with IF issue POST code appear). And I have like DDR4-4600+ish suicide dual channel. When in the Godlike I hit DDR4-4800 fairly easy. I've messing with vSOC, VDDG, PCIe Gen, disable enable onboard device, trade NVMe to SATA, Timing, VRM settings, changing DRAM, reflash the BIOS (Tried BIOS flashback & EZ flash). So far no go. BIOS is official 1302, didn't really want to downgrade the version, as I see the other didn't have the issue, and for try to make the write up of this G.Skill Neo as a Ryzen kit, using the latest BIOS, software that officially available. ? First I've seen that different board can alter the FCLK speed achieved. ? Any ideas? Thanks. ? Edited June 13, 2020 by IvanCupa Quote Link to comment Share on other sites More sharing options...

Thank you Have try 3900X, 3950X & 3500X. The 3500X turned out have the best FCLK capability based on MSI. (Just need 1.1v for 1900 FCLK there), the other two need around 1.15v+. ? G.Skill Neo 3800c14 1.5v kit BDie. The setting is just to attempt / replicate XMP setting with 1900 FCLK up & running, all auto. Then, passed the memtest, just like I pass with MSI Board. At C8I vSOC Auto is at 1.1v when running at 1900 FCLK. But I've try up to 1.35v vSOC & messing with VDDG, like I said before. Just have the workaround few days ago, Load XMP (DOCP) -> set FCLK 1900 -> minimize BCLK 1 step. BOOT, enter OS. Set back the BCLK to 100MHz. All voltage are auto with this setting, vDIMM is 1.5v set by XMP. Memtest passed. With another way, I can't POST / enter the OS like previously. It's works somehow, but must have workaround for this simple requirement & can't just load XMP & set FCLK 1900, that passed flawlessly in the other board, on this WR maker board just bumped me out. ?? Or just the silicon angel not at my side this time.. LoL Thanks for the response. ? Edited June 19, 2020 by IvanCupa 1 Quote Link to comment Share on other sites More sharing options...
speed.fastest Posted June 29, 2020 Share Posted June 29, 2020 (edited) Just tryed 2101 bios from front page, actually that bios is really good, have much better consistency than retail 1302 & 2010 BIOS. Cant pass memtest with other bios, but with 2101 BIOS it works great! https://hwbot.org/submission/4485452_speed.fastest_geekbench3___multi_core_ryzen_5_3600_36586_points Edited June 29, 2020 by speed.fastest Quote Link to comment Share on other sites More sharing options...
