(another update) at this time, im running a 5800x (FINALLY) with the SAME KITS you seen mepraise for doing 4000 c16-16 in those other shots on this review.well im back to not only praise these sticks EVEN MORE! but to state that they indeed will run 3800/1900 c14-14 FLAT at 1.54V (with proper adjustments to secondary timings and proc/drive strengths etc)ive been running these with these timings now for around a week (with a 90mm fan) without the fan blowing over them they do indeed throw errors in TM5 and HCI and y-cruncher wont even pass..(the last 4 pictures are what im running now) and i must give credit where credits due, im using a "daisy chained MSI b550 board" so its nearly IMPOSSIBLE to get something like this running right withoutcatching some grey hair here and there. anyhow, without a doubt these are some truly great sticks(ONLY FOR THOSE WILLING TO PUSH THESE B-DIE STICKS TO THE EXTREME)!now the only complaint i have, is while i have 2x8x2x8 (two sets of the same stuff there not a 4 pack matched kit but again ARE THE SAME MODELS) team switched some timings down in secondarys etc thats not stated on the main product page. so, for 2x8 these will be an easy setup, even 4x8 but when your on the edge of stability like im at now, its well....if your still reading then you already know!!still recommend these to those who wish to overclock their RAM/IMC on ryzen!(UPDATE FEB 14th 2021) (added correct photos for 4x8 config with aida benchmarks for 4x8 (16gb is 2x8, 32gb is obviously 4x8) if your not going to overclock this ram, DONT BUY team has another option for amd instead, there 3600mhz c18 kit is decently priced and will be perfect for RYZEN builds!) had this kit for a while now, and grabbed a second kit from another site ill not mention, same kits, however team switched tRC on the 3200c14 kits from 45 to 97 which isnt much a problem, or you shouldn't believe it to be. considering i was able to get 100% full stability at 4000mhz with fclk at 2000, c16 flat, with super tuned subs. included UPDATED timings and aida benchmarks to show and tell team group NOT to claim that their 3200 c14 dark pro kits wont do 4000mhz at c16. because they actually go farther quite a bit farther actually. but i could not satbilize 4 sticks at that frequency on my b550 gaming edge board. (im not an expert at ram overclocking anyhow. (stabilizing this took over a weeks time.) and i suggest using y-cruncher, OCCT, prime 95 sfft, TM5, and HCI memtest) NOT MEMTEST 86 there is a difference. just google HCI MEMTEST to stress test ram kits when you wanna be sure because HCI will stress it all, memtest will miss etc. anyhow LOVE these kits. kinda sad ive not heard back from teamgroup in my email by now. but i already figured out what my issue was. and i still have no clue what PCB revision R2 is. which from what i can find its A2 layered. anyhow you can use the timings above as a rough guid. 32gb is 4 sticks, and 16gb is 2 sticks. both are stable on my pc.UPDATE 1/7/2021 had this kit for about a month or so now, and as you can see im able to get extremely good timings with this kit on a b550 gaming edge wifi board (updated drivers/bios etc) running my 5600x with 2000fclk at low voltages with the timings im using this kit is simply put COMPARABLE TO NONE!!!! im sure theres room for more improvments and i should have screenshotted TM5, HCI, Y-cruncher stress tests and how they passed (not forgetting p95 small FFT as its a hardcore ram test) but still take my word for it. THIS IS THE KIT YOUR LOOKING FOR OVERCLOCKERS!!! just wished the price would go back down a little so i could snag another kit and run 4 sticks and see what im able to hit there, bc 5000 series love 4 sticks vs 2! (pic without hwinfo is latest timings etc, this is stable @1.4V llc3 just upped it for no reason as i thought i had to but was my cpu overclock crashing desktop. removed the cpu oc and it stopped crashing out.)as of today, ive had this kit used on a 3600xt, and 5600x both to which i overclocked the absolute crap out of this kit using the same timings on both cpus, only the 3600xt had a 3800mhz 1900fclk oc, and the 5600x has a 4000mhz 2000fclk overclock to it. i included zen timings, and my aida scores, L3 cache is low but thats a bios issue with the agesa code from msi not the ram or cpu causing this issue.my kit is the 3200c14 tforce Dark PRO, when i bought this kit i got it new for around 120 total? was at its lowest pricing yet. i cant say ive found ANY of my kits better than these as these are ALWAYS samsung Bdie! not that typhoon burner is accurate by any means telling me i have 3 kits of bdie when i only have one by using the manufactures websites and seeing what experts say i have two other E die kits from corsair LPX which wont boot on none of my CPUs, or boards for that matter. anyhow, if your into overclocking ram and want a good looking kit for your build look no further. im unsure if these will work with all coolers as you can see im using an AIO.but if ya do want a BEAST at overclocking and working on your board reguardless if its QVL certified or not then these will more than likely be what your after. REMEMBER all teamgroups ram have LIFETIME warranty! THANK YOU TEAMGROUP!!! i also have 4 other team kits as well lol!
