Ryzen infinity fabric for ZEN and ZEN+ (Ryzen 1X00 series and 2X00 series) make memory overclock more useful but complicated. Sometimes, overclock fails even if both memory modules and memory controller works well but infinity fabric fails. There are claims that AIDA64 Cache & Memory Benchmark is useful to see if that happens. If L3 performance significantly lower before overclock, it is fail even if every other test(Testmem5, HCI Memtest, Linpack, etc...) succeed. Because Ryzen (exclude APU) 1X00 and 2X00 series have distributed L3 cache across 2 CCX which connected by infinity fabric, infinity fabric fails affect L3 cache performance. So......how about allow us repeat L3 bench only (N times or time basic) ? Or, maybe adding options to see L3 performance results in already exist cache stress test ?

In past two days I have tried to overclock my laptop MSI GT75VR TITAN PRO and succeed 90 percent only.I started Overclocking in xtu and it worked well and CPU temp were 60c to 70c occasionally it spiked 75c but it's stable and with stand every test I throwed at it "Cinebench, prime 95 , xtu stress, even Aida 64 stress test"And I played CPU intensive games like Gta 5 around 3 hr and also some of Cpu intensive application from my work it still withstand perfectly and temp was too good only around 68 C (Fan speed :Auto).Until it tested with "Aida 64->Benchmark->CPU Hash" and suddenly got crashed. And then it automatically rebooted and tested again with same setting and it crashed again. I thought something not compatible with my system and it took another day to find the solution for my problem and I found two solutions1) Increase the core voltage offset -100mv to -60mv 2) Another leave the core voltage -100mv and increase the ring ration default 3.6 Ghz to 3.9 GHz And I tested with those setting it withstand most of the time,but it still crashed 1 or 2 out of 30 times.What do i do and why my overclock doesn't handle CPU Hash benchmark testing Guys i searched every forum to find solution for this problem nobody can identify the problem.So, I came here you guys are all developed this S/W and let me know what did i miss !!!

How do i undo the overclock? My netbook (asus eepc) base clock was 1000Mhz, i?ve clicked the overclock button and now its 1333Mhz, however I have to send it to repair under the warranty, and don't want to send it overclocked or the warranty is void, how do I un-do it? Thanks in advance
