Hey everyone! I’m currently putting together a new build centered around the Intel Core i7-13700K and an ASUS ROG Strix Z790 motherboard. I’ve managed to pick out most of my components, but I’m feeling a bit stuck when it comes to the RAM. I know the 13th gen Raptor Lake chips can really benefit from higher speeds, but I've heard that tightening the timings is just as important for minimizing micro-stutter in gaming and improving overall system snappiness.
I’m specifically looking for a 32GB kit (2x16GB) that hits that 'sweet spot' for performance without being completely overkill on the price. I’ve seen some 6000MHz and 6400MHz kits out there, but the CAS latency varies quite a bit. Is it worth paying the premium for a CL30 or CL32 kit, or is CL36 generally 'good enough' for this specific CPU? Also, I’m curious if anyone has had better stability with specific brands like G.Skill or Corsair when using XMP profiles on the Z790 platform.
Does anyone have a specific low-latency DDR5 kit they’d recommend for the 13700K that offers a great balance of speed and stability?
TIL! Thanks for sharing
Ok so, I've been down this exact rabbit hole with my own 13700K build, and honestly, the RAM situation is kinda frustrating. I initially tried a cheaper CL36 kit and had issues with micro-stuttering in Cyberpunk, which was super disappointing. For your Z790 setup, you basically wanna aim for the 'sweet spot' which is definitely 6000MHz or 6400MHz at CL30.
Here is what I recommend based on my experience:
1. **The Gold Standard:** I eventually swapped to the G.Skill Trident Z5 RGB 32GB (2x16GB) DDR5-6000 CL30-40-40-96. It uses SK Hynix M-die or A-die usually, which is way more stable on XMP than the Samsung chips found in most CL36 kits. It literally fixed my snappiness issues.
2. **The High-End Alternative:** If you want that extra edge, the Corsair Vengeance RGB 32GB (2x16GB) DDR5-6400 CL32-40-40-84 is also solid, though I had some weird iCUE software bugs with it.
Basically, dont settle for CL36 if you can afford the jump. The 13th gen IMC loves low latency, and CL30 is highkey worth the premium for 1% lows. gl with the build!!
Seconded!
Honestly, i went through this exact same headache when i built my rig last year. Spent way too much time chasing those tight numbers and basically lived in my BIOS for the first month.
Respectfully, I'd consider another option before you spend a ton on the lowest latency possible. I've been building rigs for over a decade, and honestly, the 'stutter' people blame on CL36 is often just a bad XMP profile or background tasks messin' with things. Not to disagree with the previous post, but for a value-focused build, CL36 at 6000MHz is actually totally fine for the 13700K. You're talkin' maybe a 1-2% difference in frames, which you wont even feel... like at all.
I do agree that speed is key for Raptor Lake, but don't overpay just for 'prestige' timings. I've had great luck with brands like TeamGroup or even Kingston lately cuz they're usually way cheaper than the flashy stuff. Just check your motherboard QVL list first. Stability is sooo much more important than shaving off 2ns of latency, especially if ur trying to keep the budget under control. GL with the build!
> Regarding what #4 said about "Seconded!" I have spent a lot of time over the years testing different memory modules on the Z790 platform, and in my experience, the brand stability is usually more important than chasing the absolute lowest latency numbers you see on paper. Some kits look great on a spec sheet but end up being a headache to keep stable at high voltages. Before I give you my full thoughts though, I need to know what kind of CPU cooler you are planning to use? Some of the higher performance modules have really tall heatspreaders that might not fit under certain air coolers, so that definitely limits your options. Generally speaking, you basically cant go wrong with anything from TeamGroup these days. I have found their bins to be very consistent with Intel chips. Kingston is also a very solid choice if you want something that is just gonna work without any drama. Just grab a high-speed kit from either of those and you will be in good shape for a 13700K build.
Can vouch for this
