operating at 3600mhz with reduced performance
Hello, you're considering increasing your RAM speed from 2400MHz to 3200 or 3600MHz. Since your CPU (i3 10100) only supports up to 2666MHz and your motherboard can go up to 2933MHz, running higher speeds now could cause stability issues until you upgrade both components. Running at lower speeds temporarily might help avoid problems while you plan the next steps.
Unless you turn on XMP, performance will likely be around 2666 MT/s by default. Without XMP, RAM will operate at speeds approved by JEDEC standards. Review the ratings of the RAM you're considering, but typical rates are 2666 MT/s. Higher speeds generally need XMP enabled (the fastest officially supported for DDR4 is 3200 CL 20). If you intend to upgrade your CPU and motherboard, it would be better to choose components that support DDR5, as this would prevent reusing the existing RAM. It's usually more practical to purchase all parts together.
Consider 3200MHz CL16 for future upgrades and compare Corsair, G.Skill, and Patriot RAM options.
3600 MT/s CL18 offers comparable theoretical latency to 3200 MT/s CL16, yet performs better. CAS latency is expressed in clock cycles; a larger value at higher frequency doesn't always indicate slower performance. (General guideline: latency ≈ CL × 2000 / speed; 3600×2000/3600 = 1600 / 3200 ≈ 10 ns)
Which motherboard? B560/z490/z590 supports high speeds easily. The rams should generally run smoothly; you might hit issues only with older 9th/10th gen iMs, which usually cap around 4200-4400 DDR4 with stable voltages (~1.45V). That means the CPU speed isn’t a big factor—just make sure it’s compatible. Prefer a 3600 if it matches the price range (+/-5$).
All the heatsinks are mediocre because most 3200C16 and 3600C18/16 models use random ICs, leading to potential failures like Samsung die cases. It doesn’t really matter which brand you pick; as long as you find a cheap one, it works. At least pick the lowest price and get decent ICs—cheap options often offer good performance if you choose wisely.
If you want top performance, consider a Samsung BDie (3200C14, 3600 16-16-16, etc.) or opt for OEM bare PCBs with DDR4 (like M378A1G43EB1, HMA82G6DJR8N, 8GB double-sided E die, 16GB double-sided DDR). These let you select reliable ICs and even get dual-sided modules for extra speed. Manual tuning is required, but gear 1/<4400 OCs are pretty straightforward.
