It was really fun overclocking this memory kit and it didnt disappoint me in terms of performance. Although the XMP profile worked out of the box on my X570 prestige creation mobo, it probably wont work on cheaper motherboards with less pcb layers. In the end I managed to overlock it to 14-13-13-26 at 3933 MHz (which was the sweet spot in terms of performance for me). 4000 MHz definitely works even at CL14 for me but I get usb issues on Ryzen (Im running a 1:1 ration of memory bus to infinity. Fabric clock) so I chose 1967 MHz.

This ram set is something I took a gamble on. I know that G.Skill support will instant auto reply to this review saying not on QVL list blah blah blah so you can't hit the advertised XMP profiles. This is mostly true from my own testing, but it seems little shy of being able to hit the advertised XMP speeds. On my AMD system I can get right up to 3933mhz/1933 fclk. I can technically hit 4000mhz on my system IF, and a big IF, if I set the dimm voltage to 1.48. That's rather high for me and it seems like there can be additional bios compatability updates that might be able to address this. For the meantime the ram seems to work fine set to 3800mhz/1600mhz fclk. Don't expect to tighten the timing much, if at all. The memory modules are not great being Hynix ...

The bottom line is that it's a decent value kit for those looking for 64gb with an option to expand up to 128gb if needed. Just don't expect much if even the XMP profile settings on AMD.

I didn't do my homework regarding the RAM situation with the latest hardware. I thought XMP settings were still plug-and-play as long as your motherboard supported the clock speed. I found out it's more complicated now. I'm using this with an ASUS TUF GAMING X570-PRO (WI-FI) and a Ryzen 5800X, and it doesn't seem to be as compatible with the motherboard as I hoped. I can get it stable at the XMP timings at DDR-3866, but can't get any higher even with relaxed timings. I can't get the motherboard to accept a CAS17 setting even at DDR-3600. I was hoping for better, but that's probably my fault. DDR4 is complicated now.

I'd only recommend this RAM if you have a pretty new MoBo and this exact line is on the QVL. I have an ASUS Z370 motherboard that will theoretically run RAM at 4000Mhz, and the QVL contains a similar line of DIMMs from G.Skill with similar specs. Before this I was running 4 DIMMs in this exact Ripjaw line at 3200Mhz, but I needed to upgrade capacity and thought I'd upgrade speed too. My first order of this RAM wouldn't even post at anything faster than 3000Mhz! Auto-tweak in BIOS stopped it at 2800 - much slower than the price demands. So I sent those back as defective and got a replacement pair. The second pair runs rock stable at a max of 3417Mhz, and about 99% stable at 3550. Anything faster won't even post, but I can partly blame the motherboard/QVL for that - ... MoreI'd only recommend this RAM if you have a pretty new MoBo and this exact line is on the QVL.

One star for not being dead on arrival. Another stars for it not being useless. (Hmm, for some reason I can't set this review to two stars... ok one star it is? Newegg, come on...) Tested: CPU: AMD Ryzen 9 3900X MOBO: Gigabyte X570 Aorus Elite Wifi Going through many RAM overclocking guides and how-to videos, it's clear to me this RAM has issues with my setup. I barely got this RAM to run at 3333mhz. Forget 4000mhz. I would be completely happy if it ran at 3600mhz. NOPE, I couldn't even have that! Very frustrating buying experience. Here's important advice when buying RAM: Check your motherboard's RAM compatibility/tested/supported/qvl list and be very cautious buying outside that list.

I really did not need al that memory, but wanted it for bragging rights. I don't even know if the memory is working at full speed, or if motherboard throttled it back, but the extra speed on the sticks did not cost more per GB, so better to have for resale later. I wanted to verify the multi quad channel operation, will need to run memory speed tests sometime to verify the difference. For that matter, I did not need the 18 processors with Hypethreaders on the extreme processor, but looking at 36 processor cores in my device manager, is good for more bragging rights. Then of course, why not get the 980 PRO NvME, more money thrown after more good, I do not know if I will get the advantage of the 7GHz speed as I do not have PCIe 4.0 on my X299 motherboard, but got the ...

It's designed for Intel XMP and doesn't hit 4000mhz with a ryzen setup. I am running 4 sticks and I know that can make OC harder, so I was happy to find out that enabling the XMP profile and down clocking to 3800mhz, it works. If you buy these for an AMD build and feel comfortable messing with the overclock settings to make these sticks work, it's still good price/performance. Otherwise, it's expensive 2133mhz ram. I'm very happy with them at 3800, because due to some research, knew they weren't a direct fit before purchase and was only expecting 3600. -1 star to draw attention to people reading reviews to know the average user isn't aware there's a slight incompatibility and isn't getting more than default 2133mhz from these if they aren't comfortable with playing ...

Check your motherboard Qualified Vendor List and make sure this product is on it. I have an ASUS PRIME Z590M-PLUS with 11600k and can get 4600MHz, though I have to use XMP 2 to get up to 4600, otherwise XMP 1 only goes to 4200. No stability issues yet. UPDATE: Got a few CTD's and one BSOD in the last two days, with debug files suggesting memory issues. I ran memtest86 with the RAM frequency at 4608MHz and got 70+ errors over 3 passes. Slowed it to 4331MHz and got a few errors on the 2nd pass, so I brought it down to 4060 and cleared 4 passes. So for me it's effectively a 4000MHz RAM selling at about the right price range, but had I not done this testing and changed the frequency, I could have corrupted important files.
