" rel="nofollow - hello, I need urgent help. I sent my faulty Asrock X370 K4 to service and they approved to replace me for some other mbo. They don`t have much choice in store, but they have Asrock X470 K4. No money return because I was told that service still can get x370 k4 which became EOL last year in June. On x370 K4 I couldn t achive full speed, even on 2933 it was crashing. Is x470 K4 good, free of any problems? https://asrock.com/MB/AMD/Fatal1ty%20X470%20Gaming%20K4/index.asp I think my memory is listed on memory vql but I am not sure since this memory has couple of versions. Also my CPU is R5 1600...

memory support depends more or less on memory controller which resides in cpu ...to some extent support may improve a bit with different bios version as they apply different sub timings in auto mode, but i wouldnt relly on that too much as for llc..u wont need it, its not good for ryzen anyway ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

why is LLC not important, I found out couple of post that say this is a big drawback for this board?

im not sure with x370 k4 as it has old vrm design as for llc...and its general purpose lets say on idle voltage (vcore) u have 1.375v but once u put load, there should be slight decrease of voltage once u start oveclocking, voltage can drop pretty low during load (1V or less), which may result in unstable PC llc and its Level settings should correct those voltage drops (VDROOP) mine K10 has no issues with missing LLC and even if it will be there i wouldnt use it, voltage under all core load can get pretty high (under cpu controlled mode) ------------- http://valid.x86.fr/diq4l4" rel="nofollow"> http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

One user wrote on overclock forum this: "There doesn't seem to be any LLC options that I can find yet, and when trying to overclock the processor there seems to be quite a large amount of vdroop, like .05 to .075v from 1.45 to 1.4 or under." Even if I get over LLC, memory compatibillity still bother me. When ryzen was released I been told that x370 K4 would probably go over 3200mhz, that I just need to wait for new bios. We all saw how that turn up, worst board for memory on am4. Since my x370 k4 had some bios corruption screen it ended up on service and now is the perfect time to correct memory compatibillity mistake. |

i have the X370 Gaming K4. it Does have LLC, uses the better VRM. some say LLC is not needed i would strongly disagree. you can either set your voltage really high so that after droop their is still enough to stay stable still have to stay in the save zone before droop. Example. 4Ghz with LLC 1.425V LLC 3 will hold around 1.41v under load 4Ghz no LLC and you need over 1.45v to keep it around 1.41v under load in this case we are trying to stabilize 4Ghz oc that will run fine with 1.41v but it cant be done safely without LLC because you are forced to overvolt too much without LLC to compensate for the Vdroop But as already stated its the worst Ram support on AM4 truly is just the worst when it comes to ram. ------------- ASRock Fatal1ty X370 Gaming K4 P3.40 AMD RYZEN 7 1700 @ 4Ghz 1.39v Noctua NH-D15 "blocks top 1x pci-e" 16GB GSkill Ripjaw V F4-3200C16D-16GVRB @ 2933 14-15-15-15 T1 1.365v GTX 1080 x2 Sli |
