Bests & Worsts Reviews from Amazon

I received my 3733mhz kit today and sadly it is not Samsung B-die (Hynix for me) nor stable at the advertised speed on my Ryzen 3700x/x570 motherboard which is a disappointed fail on both ends. I tried getting it to the rated speed and the board listed the correct timings but it would just instantly crash on boot no attempt given and default to 2133. I set the timings really loss and tried, same result than turned to Ryzen Dram Calculator and they do not support my kit about 3400mhz so I can't even really tighten the timings much let alone hit the advertised speed. I've kinda given up for now after trying 3600, than 3400 and just used one of the generic speeds MSI recommended (3200 16-18-18-36) which is sad but has been stable the few hours I've been using it but still disappointed I spent near $100 for this and while that's not crazy money that's certainly B-die money area and yeah.. For what I'm getting out of it could have just went with G.Skill 3600 and saved $30. I don't wanna be overly harsh on it but I had 3000mhz ram which worked fine I just wanted the bump in speed =/ I paid $40 less for my previous ram over this so it really hasn't offered me anything I've had except for a $97 lighter wallet. 500mhz off isn't massive but it's the difference between $50 ram and $100 ram I just expected better from it, I really only went with this as I have a Patriot M.2 and it has been solid for me so I felt I would give them another purchase but next time I'm going G.Skill/Corsair =/ --update-- Been using this ram for a few days now and PC has crashed 3-5 times. Every time my motherboard informs me my memory overclock has failed. Not even stable at 3200 16-18-18-36 with 1.37v --UPDATE-- Amazon sent me an exchange kit of ram since I was having issues and not reaching rated clock, was happy thought problem solved I booted down the PC, let it cool cleared CMOS than replaced the ram. Put system back beside desk and hooked it up, loaded into BIOS and enabled AMP (AMDs equivalent to XMP) saved settings than clicked reboot. PC turned on loaded into started to load into Windows and BSOD... Odd but rebooted system went into repair mode, couldn't repair. Shut system down, cleared CMOS and went into BIOS to make sure everything was set to default and tried again. Same message, couldn't boot into Windows, unplugged system put old ram in and ... Same message. Spent 4 straight hours trying to get into Windows and nothing tried troubleshooting and nothing. Tried Safe Mode and nothing, went into troubleshoot, click Command Prompt checked disk no issues, drive appears (drive hasn't failed) so after everything thing the replacement ram for the ram which wasn't stable at -500mhz below advertised speed corrupted my install of Windows... Lost everything across 4 drives ... 3.6TB's of data.. I'm furious to put it mildly... All this after working for 12 hours... Faulty ram replaced with more faulty ram which corrupts windows install and takes everything on all my drives... I regret buying the original faulty ram, I regret the replacement to the faulty ram, I regret everything related to this product. I now get to spend the better part of the next week restalling everything on my system. In the 15 years I've been building PC's this is the safest excuse for a high quality product I've ever seen and I will personally make it my mission to discourage everyone from using this product. My poor experience was simply made worse ...thanks I will have to deal with this another time as I have work in 6 hours...
