Corsair CMK8GX4M2B3200C16R Vengeance LPX 8 GB (2 x 4 GB) DDR4 3200 MHz C16 XMP 2.0 High Performance Desktop Memory Kit, Red

Perfect upgraded my 16gb kit to 32gb

They have worked so well, I have now bought a second pair to give me 32Gb...... over doing it? Nah

Review: 26.10.20.I have two sets of the 8x2 kits . I've read some reviews and they state they can't get 3200 Mhz XMP that is probably because they haven't enabled dual channel mode.This is why you should always read the manual.As I'm using a R7 2700X on a Aorus Elite X570 (Rev 1.0).The following step is for AM4 boards only:Ram MUST be added in this order: A2 (always first), B2, A1, B1 (see uploaded image).I bought the first kit last year (6th October 2019) and the second kit this year (3rd Jun 2020) along with 2 other kits - 1 has been used in a B450 Mortar Max Build for a relative. The other I have kept as both a spare and upgrade kit for aforesaid relative - All 4 kits are the exact same.I have run the RAM on XMP at 3200 Mhz on a single set of 8x2 without any issues hence 3 more subsequent purchases of the exact same kit and version number. XMP always set the ram 1.35 volts and with the +0.030 it ends up at 1.380 volts... much too higher for my liking. The kits I've got - the two sets I've used have the same behaviour - perfectly happy at 1.280 volts.But using the XMP profile puts the ram at 1.35 volts and the motherboard adds a plus offset of 0.030 volts. So the ram ends up fluctuating between 1.38 volts and 1.35 volts, 99.9% of the time stuck 1.38 volts.. a tad too high for my liking as I plan to keep these RAM kits for a loooong time.Given that the memory controller is on the CPU and the infinity fabric is tied to the memory controller on Zen + (Plus Zen + CPUs are poor overclockers compared to Zen 2) I had to settle for 2733 Mhz with 4 x 8 (with a little loose timings) and any higher I will have to reduce the overclock the CPU or increase the voltage on the CPU and RAM to avoid memory errors. Additionally, any higher than 2933 Mhz on 4 sticks the latency penalty is quite noticeable, on 2 sticks is there is hardly any which is why it's always recommended to use XMP on two sticks.Additionally the RAM is also currently undervolted to 1.290 volts with a motherboard offset of +0.030 volts / -0.054 (this cannot be adjusted). On reduced loads motherboard drops it down to 1.236 volts (lowest I've seen).The R7 2700X is overclocked to 4050 All Core with a drastic undervolt, this gives both thermal headroom for sustained loads and very low idle temps with the Artic Freezer 34 Esports (single fan) - see hwinfo (current ambient temp 24.7 degrees celsius). Additionally, my room becomes too hot with stock or higher voltage and given last summer was extremely hot...You may wondering why is CPU VDDP18 is at 1.6 - that is the lowest I can set it in the BIOS and PM_1V8 at 1.6 volts, that is the lowest I can set without needing to clear the BIOS (default for both settings is 1.8 volts and that's perfectly normal apparently from what I found looking for the information I've come across on the web).I can overclock it higher but the ultimately the performance difference is not all that and there are stability issues albeit very few and far in between crashes but they are crashes never the less (see Cinebench results).During the past year of getting my PC to a point in terms of stability and peformance I have seen some bizzare things lol... See the last two screenshots.The motherboard automagically overclocked the CPU to 4261.89 and the ram to 3253 roflmao... I've seen this happen several times and I only had a usb stick plugged on two occassions hence only two screenshots.Yes, I'm aware I could have saved some money by getting slower sticks than 3200 and sticking them at 2733 and gotten tighter timings. For me that would be a waste of money as I plan to upgrade to Zen 2 or Zen 3 in the future and when I did I'd have have 32 gigs of ram lying around without much use as by then DDR5 will be out and there would be effectively zero demand for low speed DDR4s. So I'd be better off getting decent kits that can overclock decently and last me two or three CPU generations.All in all, these are decent kits - highly recommended.

Good quality ram can’t go wrong with Corsair

all supplied quickly and worked out of the box and on Sunday too keeps the wife happy and now me too

Amazing ram for the price

I've had no issues with this product and it's unlikely I'll have any problems pop up for at least a decade.

Installed mostly easily, and for someone with 0 pc hardware skills. Hopefully they last a few years.
