I'm eyeing the Patriot Viper Xtreme 5 DDR5 8200 MHz UDIMM Memory Kit on B&H Photo and noticed some conflicting information regarding the timings. Buying separate kits of "the identical memory" does not guaranty their actual sub-timings or whether or not they are single or double sided. DDR5's memory bandwidth efficiency/utilization improvements might help with that, and even with the loosened timings, the bandwidth will probably be more important for an iGPU than the memory latency anyway. It gets confusing when some timings are slower but some are faster or the clocks are higher but the timings are slower. They aren't worth the extra $15 for most people, because not all boards can run DDR5 7400. For example, ddr5 6000mhz cl30 has an effective speed (first write speed i think its called) of 10ns, which is the same as a ddr4 3200mhz cl16 kit. For a 5600 kit, you might be able to do CL30, otherwise CL32 is your most stable option at 6000. but I don't know how I'm supposed to differentiate between a RAM module with a speed of 6000Mhz at 30-40-40-96 Timings and one with 6200Mhz and 36-39-39-76.
