Hi, i have been a silent reader of Tom's Hardware, it has been an amazing forum.

I have an issue with my laptop and was wonder if someone here can help.
Laptop: Asus S550CM
CPU: Intel i5 3317U
RAM: 4GB
Storage 750GB + 24 GB SSD
Windows 8

So last week i upgraded my laptop with 8 GB Kingston RAM & 120GB Kingston V300 SSD. I did not clone the old hard drive instead i just saved its image.
Everything on the 120 GB SSD was fresh installed, there are no missing drivers from what i can see.

Now the 24GB SSD is a waste as its not being used. i Guess i can use it for downloading & stuff but I want to try to setup SSD Caching on it as it was before with 750GB Hard drive. So the 120GB SSD would be the Main one with OS on it & the 24GB would be the Caching SSD.

But i cannot seem to get it to configure, Accelerate tab on Intel Rapid Storage Technology is missing even though i have installed the drivers multiple times.
It shows both the ssd's but would not let me configure it.

Before when it was the 750GB + 24GB windows would boot up in 3.5 Seconds. now that its all on 120GB ssd it takes 5 seconds. but i want to make that quicker.

Is it even possible to setup a SSD to Cache to an SSD? I have seen other posts some say to enable RAID in BIOS but my BIOS only has AHCI / IDE nothing else.

In computer management the 24GB SSD has a 40 mb OEM partition i guess that contains the serial for windows 8 etc. and the rest is unformatted / unallocated space. Should i Delete the OEM partition & see if it works? or am i Missing something?

I'm not sure if it is possible to cache an SSD (Intel may disable this option), but even if it were, it would be a downright horrible idea.

Furthermore, Intel's specification sheet for the HM76 Express chipset lists Intel Smart Response Technology as being unavailable on that platform, so I'm not sure how it was working in the first place.

Why would it be a horrible idea? It would work the same way it works when its HDD + SSD?

The whole purpose of using an SSD to cache an HDD is to reduce the access time of frequently accessed blocks. Whereas hard drives have a random access time of between 10 and 20 milliseconds, SSDs have a random access time of <1ms. Since caching by definition takes advantage of some disparity in performance, there would be no more benefit in using an SSD to cache an SSD than there would be in using an HDD to cache an HDD.

does the 24gb ssd still have the previous cache partition still on it? try deleting that partition and see if you can enable it then.

No partitions on it except for the partition called OEM which is about 40mb. the other space is unallocated
