Change Log:

Magician version 4.5 features a number of improvements over version 4.4:

• New model support : 850 EVO
• Improved RAPID v2.1
• Reduce the CPU Utilization during Magician launch
• Enhanced SATA Interface view and Over Provisioning
• Update Magician GUI and Help file

 

Cheers, have just updated to latest version, improved RAPID v2.1 hey, I wonder how improved it is, will see if I can find more detailed release notes.

EDIT: nope, no more release notes other than the info you posted.

 

What is your experience of the update?

 

No changes that I can see papusan, except the number switching from a 4 to a 5! Decided to run RAPID for the last couple of days, no detriment to performance, but no noticeable gains either - to be fair I don't push the system with the way I use it anyway (internet, gaming, simple office applications). Will leave RAPID enabled though just for the theoretical benefits!

 

Deleted you previous version or overwrote you with the new? It is probably best and delete the old and clean before installing the new one.

 

still too early to judge, plus I don't use RAPID mode even though I have 32 GB of RAM

why? Read meh = A closer look at RAPID DRAM caching on the Samsung 840 EVO SSD - The Tech Report - Page 8

 

all RAPID mode does is cheat the benchmarks to make them benchmark the RAM instead of the actual SSD.

Lemme ask you this bro..... caching is supposed to place the most used data or programs in the RAM CACHE for faster access right?

But......wait a second.....

1) I don't see how Magician will be able to figure out what to place in the RAM

2) Windows SUPERFETCH already does that

3) test this.....

Copy a huge 10GB + video file or whatever large file you want from your C: partition to another partition on another disk......

you will notice that the Windows file copy progress finishes insanely fast.....the moment it finishes the copy, I want you to restart your system

then check that file you copied, it would be corrupt, reason is, yes the file copy progress finished fast, but it didn't finish really, all it was doing is copying the file from your RAM cache (RAPID) onto the real disk.

so it's just cheating + placebo effect

 

Deleted you previous version or overwrote you with the New ? I've also heard that Rapic Crap can create some trouble if you have a juicy overclocking of the processor and memory. I also have 32 gb ram so instead of using Rapid Crap is better and create a RAM disk ..

 

Or simply let Windows do its thing with SUPERFETCH and forget it. SSDs will launch stuff faster than you would blink your eye anyway so caching is pointless to me

 

I decided to install over the top, but I waited to see the "old version detected, would you like to install new version" message before going ahead with the update - I did it this way because I wanted my settings to be saved from the previous version (and perhaps to retain any learning that RAPID had done previously). I checked the files where the program is installed and they're updated to the latest version, so I think it's updated ok.

Thanks for the link, looks like RAPID didn't do so well in the trace based testing, although other sites I've read have shown RAPID to improve trace based testing & other workloads, so there's some inconsistencies somewhere (or maybe just with RAPID!). I don't think they say what version of RAPID they're using at that link, it should be 2.0 based on the date of the article, but possible it's an older version, and they're only using 8GB RAM which means they're limited to a 1GB cache as opposed to a 4GB cache when using 16GB RAM (my setup). At the following link with a 4GB RAM cache there are some small improvements:

(Yep, I know about the data loss risk, not really a risk if you have a stable system and laptops have their battery as a UPS).

 

True, but Superfetch is deactivated when you put in an SSD (or at least it is advised to leave it disabled); Windows will still cache previously accessed data in RAM anyway, but it doesn't remain from boot to boot, and also only possible for certain data to be retained in the Windows Cache, whereas RAPID can accelerate other types of data (I'm not clear on the details of distinction). Also, I've found that most of the time RAPID only uses about 1.3GB of RAM for RAPID on a consistent basis, which then jumps up to 4GB sometimes (temporarily) when doing disk intensive loads, all the other remaining RAM can be dedicated to the standard Windows Cache (I normally end up with about 10-11GB of cached data in the Windows Cache by the end of a day - an amount that has not been reduced since starting to use RAPID).

 

Yes, I can imagine that if the RAM & CPU are not 100% stable then there's even more scope for data loss/corruption, always good to have thoroughly tested RAM & CPU overclocks.

 

Using a ram disk is somewhat more stable than Crapid simultaneously is a Ram Disk more widespread and tested than Rapid. If one has 32gb ram it is a waste to use Crapid. It's overkill with 32gb ram but then you can cut out most of the virtual memory on ssd and use the space for something reasonable. For example overprovision and simultaneously create a large ram disk.

 

Yes, no point in a Page File for me (don't have that nor a hibernation file). I don't want or need a RAM Disk, and RAPID is easy to implement & doesn't use much RAM (and uses it dynamically) - I'll stick with RAPID for now!

 

I am getting some weird problems with Magician 4.5

When I clicked on the Over Provisioning section the little spinning circular arrow started moving and hung like that a bunch of times

Then when I got to enable RAPID it is greyed out?

 

Does your system meet the minimum requirements for using RAPID? In Magician it says what the minimum requirements are on the same page where your enable it. For your over provisioning, you don't need to use Magican to do that; you can use Disk Management in Windows & shrink your last volume on your disk to leave yourself with Unallocated Space, which is the over provisioning area (that's all Magician does anyway).

 

Oh you're right there is a requirement problem


OS : windows 7 and above : "Error in Obtaining I..."

I'm using windows 10, damn, magician 4.4 works in windows 10 wth going backwards lel

 

That could be the problem then, although strange that the previous version worked, maybe just downgrade to version 4.4 until the next version is released.

 

Yeh I think i'll downgrade. That or I go back to windows 8. Though there wasn't anything wrong with the last magician!

 

They updated Magician to support the new 850 Evo, but they also updated the RAPID version from 2.0 to 2.1 and they said they've improved the RAPID function in version 2.1.

 

This experienced one member of a Norwegian forum with Crapid (I have only translated with Google translate) It is not always new software works as it should ..: Wow. I have a Samsung Evo 840, and have installed Samsung Magician well. When I turned on the computer today I got a popup with the message that there was an update to the Magician, from 4.4 to 4.5, and yes / no installation. I chose yes, update happened, I turned on the Rapid mode again (it had to be turned off during the update), the machine clicked off and ... would not start again.

Windows logo barely had to prove on the screen before it got a Blue that lasted a quarter of a second. Then straight into something diagnostic tools in Windows. A scan which found no solution, I was told to disconnect any USB gadgets (none were connected) and try again. Jadda ...

On the third attempt with the tools I got opened system restore and rolled back to before Magicianoppdateringen and the machine works again.
Magician nag again about updating. Not quite sure if it's such a good idea ...

Anybody know how I turn off Magician's automatic search for updates? I find it not in the program.

 

Yes, so RAPID has caused problems for some people, it's hard to say what is the cause - like you said before if you're overclocking your CPU & RAM and it's not proven stable then it can cause corruptions with RAPID enabled, maybe he was one of those people, or maybe there's a risk involved anyway. I don't know, but I'm ok using RAPID for a while, I have backup images I can use if my system becomes corrupted, but I'm confident that I won't need to use them.
