This, or something similar has probably been asked a bunch! Topic is solved

But I'm going to ask anyway! Because everyone has different systems and setups, right?!

My current disks are:
-Samsung 970 Evo Plus 500gb (OS, Main Games)
-Intel 750 PCIe 400gb (Storage, Games)
-Samsung 840 Evo 500gb (Storage, Games)
-Some unknown(forgotten) 4tb Mechanical Drive that's super slow (Storage, Selfies, kid pics, etc, as you do! )


I don't intend on using L1 caches. I have 16 GB of ram and I'm bad at leaving tabs open and stuff in browsers and just assume I'll slow down my whole system trying to find a sweet spot. So, would the 970 Evo benefit from getting L2 Cached to the Intel 750 or Samsung 840? Or should I just leave it be?

Thanks for any advice!

The golden rule with Primocache: don't cache a SSD with a SSD.

The one exception is if you had a super-slow old-gen SSD that you wanted to cache (via L2) with something like a new NVMe. It's doubtful your motherboard has newer NVMe capacity, but if it does you might think about a single super-fast NVMe as a L2 cache against all of your drives.

However, having said all of that: if you setup a 2-4GB L1 (RAM) read-only cache task, you'd see some benefit with your most-used apps/games. You can probably afford to lose that small bit of RAM for what it gives you, but I'd apply it to your most-used volume (probably C:) only.

Thank you, Jaga!

Hi hi!

Following up! I managed to get some ram on sale and use an L1 Cache now. Here are my settings:

Any info on changes for better results would be greatly appreciated! My drives are still the same as listed above in the OP and I mostly play World of Warcraft if that helps.

Have a fantastic weekend!

The config looks good. Check your cache hit rate while being in the game. I have similar settings with 32 GB total RAM and 12 GB cache. While playing Halo games I am getting around 70% hit rate. I guess this is on the top (or rather bottom) of the Windows file cache and the total percentage of content loaded from RAM is even bigger.

Yep, looks like a much better hardware config for optimum performance with that extra RAM. The only way to fill up the cache is to repeatedly load/play the game. Over time your hitrate will increase as data from the game is re-read as needed, and it's performance will improve. Provided you have low-latency network communications with the server you are on, the drive will help with things like area loading and eliminating pop-in/jitter.

As a side-note.. I use a utility that does checksum computations on folders (and subfolders) which seems to help reinforce those files with the cache. You can try it yourself - there are free checksum tools available on the web.
