I have a laptop with a 8GB SSD drive for cache, but I have it disabled because it eats 1GB of memory. As far as I know it's supposed that ExpressCache should return that memory to the system when its needed, but that's not happening.

I just made a test by reducing my pagefile to 16MB and opening too many tabs on my Opera browser. I've also been checking the amount of memory used by ExpressCache with ECCmd.exe -info. After that, Opera just died and ExpressCache was using 1GB of memory all the time.

Windows complaining about low memory while ExpressCache is using 1GB

In the image you can see how Windows shows a low memory error while ExpressCache is using 1GB.

  • Model of laptop? Version of ExpressCache? Might be helpful, depending on your version.

  • The laptop is a Samsung NP700Z3C, and you can see the ExpressCache version on the image: 1.0.94. I'm seeing now a new version, I'm going to see if I can update it, but the Samsung utility doesn't show it: more crappy software :P

Yes, it's normal for Condusiv Technologies ExpressCache to use that much system memory.

In most cases, I'd recommend using Intel Smart Response Technology instead, but it requires a minimum of a 16GB SSD.

Another alternative is moving your hibernation file (hiberfil.sys) location to the SSD. This requires no software, and allows your laptop to go in and out of hibernation (aka "suspend to disk") very quickly. This is how a lot of Sandy Bridge-based Ultrabooks were configured by the manufacturer.

  • According to your link my ExpressCaché is not working properly: "Once the system requires additional memory for other tasks, the memory that ExpressCache is utilizing will be returned to the system pool for reallocation."

  • @JotaGe Yes, well obviously it's not working as advertised. I don't think Condusiv distributes updates, so it's up to your laptop manufacturer.

  • God I'm sick of crappy software :P And using the SSD as hiberfil is not useful to me: I don't care a lot about shutdown time or startup time, and if I care, I suspend my computer. Also the key is combine HDD and SSD to achieve the best performance, the 8GB SSD is just 100MB/S, is not much faster than the HDD on secuencial reading. I wonder if ReadyBoost would be useful. BTW: Sorry about my English.

  • @JotaGe Just to clarify, hiberfil.sys is for hibernation (aka "suspend to disk"), not startup or shutdown. If you're only using sleep (aka "suspend to ram"), your battery life will suffer considerably.

Well it's been almost two years with no solution, I don't know if there is one but all this time I've been using the 8Gb SSD as pagefile (without ExpressCache) with no problem.

It makes the laptop faster and I think is the best use for the SSD if you don't turn off or reboot frecuently. I now have a full SSD and I still using the small one as pagefile.

I think it also helps with hibernation times too.
