Looks like a fine enblocal.ini to me.. Except you have UseDeferredRendering set to false (and thus UsePatchSpeedhackWithoutGraphics set to true). I think this disables all the graphical modifiers like SSAO DOF Reflection etc, is this on purpose? I'm not sure if it has any negative impact on ENBoost (the memory part) though, probably not. Maybe try fiddling around with ReservedMemorySizeMb (512, 768, 1024? I somehow get the best results at 512) but it seems weird to me that you have so many CTDs.. I have a newer card but also 4Gb VRAM and have set a similar VideoMemorySizeMB which seems to work fine. You could try EnableOcclusionCulling=true for potentially some more FPS but I don't think it will fix any CTDs.
I don't use memory blocks log or SSME and I rarely crash because of memory issues unless I downsample to like 4k resolutions. I have never used a log to confirm if the SKSE.ini memory patch works but I did try tweaking SKSE.ini in the past which led to instability, so I assume it is working properly with its default settings. I have it just in my Skyrim Script Extender -> SKSE folder in MO, so I don't know if moving it directly to the Data->SKSE folder will make any difference.. Btw I don't think you should do anything fancy like 'converting' a text file, you can easily make any .txt file an .ini by just renaming it after unchecking the 'Hide extensions for known file types' option in map options. (that way you won't ever make those obnoxious xxx.ini.txt files again)
As for mods, what options do you check in the ASIS SUM patcher? If you are using things like increased spawns, that could potentially mess things up. If you do use increased spawns and all that stuff with ASIS you should get the 'ASIS Improved INI Files' from the Nexus. And do you use Interesting NPCs? That mod has an Alternate Start patch that you should probably use. Other things I can think of are your regular Skyrim inis.. if you have tweaked them a lot (not counting the SR:LE tweaks) I'd suggest removing those you added or restoring them to default values, especially any Papyrus tweaks. Tweaking SKSE.ini has only caused me trouble so I'd refrain from doing that, but it might work out perfectly fine for others. Another thing to mention would be the recent switch from ELE - Interior Lighting Merged to the new ELE Lite. The SR Conflict Resolution esp changed a lot with that, make sure you have the most recent version of both that esp and the guide.. And rerun the RSPatch, that recently caused me some issues :p
Finally about your GPU usage.. it should be that high! That only means your GPU is doing its work. At times it will drop lower because Skyrim is being an unoptimized piece of **** again :p Try to monitor your GPU in modern well optimized GPU-heavy games, you'll notice that it sits near 99% most of the time. That just means you're getting the most out of your card!
