r/overclocking - for those who like to push their chips a little harder

Hello,

I currently have a 7800x3d and wanted to upgrade to better looking ram.

I found these two kits and was wondering if its possible to underclock a 7200MHz cl34 kit to 6400MHz cl26 or an even lower cl timing (26 is the lowest cl timing I see being sold so I am also curious if it can go lower).

My current ram kit is TEAMGROUP T-FORCE DELTA RGB 32GB (2x16GB) DDR5 6400MHz CL32. I am able to get it to run stable at 6400mhz and cl30.

The two ram kits im looking at; I live in canada so its a canadian link to a canadian store.

I know alot of people will just tell me to buy the lower costing one and the preformance difference is marginal. But personally I feel like I can feel the diffence after increasing the speed from 6000 to 6400 and lowering the cl timing. Even if it is placebo I would still appreciate if people could tell me what kit would preform better between the two and if it was possible to underclock the 7200mhz cl34 kit to a 6400MHz cl26 or lower cl timing kit and would it preform the same compared to buying a stock 6400MHz cl26 or lower cl timing kit. So I can base my decision off of that information and factor in price to preformance in there. Thank You.
