current WR for just a ramclock aka just a cpuid is like 2250+, was done on ch4f with gtx 1 ram with loose timing by cpt planet. I'm not big on just suicide shots though, I like to find usuable fast and performance oriented speeds that i can bench with.
as far as 32 m goes I have done a bunch of 1m/32m on ch4f.......not sure if you would call them ram records but no one has matched them yet.
Here's a few of them. All of this done on ch4f
Unganged is alot harder and packs way more performance.
