Asrock xfast Ram Utility Info

post #1 of 5
Thread Starter 
Was looking to get some info on Asrock's Xfast Ram Utility, tried looking on the net and couldn't find much, was wondering how it works and what it can do for me? Thanks!

Basically what it does is it makes a virtual ram drive or a ram disk. It allocates however much ram you want to use and turns it into a drive. Ram disk can be used for many thing such as a scratch disk for photoshop users, you could turn it into a temp drive so it doesnt use your SSD or HDD. Now RAM gets deleted or erased after a shutdown/reboot or power interruption but if the information is saved on a harddrive it would be recreated. Pros are if you have excess amount of ram it would be useful, it will take loads off your SSD/HDD, if you're using it as a scratch disk it can save a lot of write/rewrites for those people who do a lot of photo editing and will help extended SSD life though I think SSDs last a long time unless you constantly write/rewrite gigs and gigs of data everyday for the next 5 years lol.

Overall I see the benefits of it if you have excess amount of ram, or even if you only use like 4GB of ram and you want to dedicate 2-4GB for something else it can become useful. ASRock does have a utility for this but you could also use a 3rd party if you wanted to.

Note: Its funny how they advertised it, why would you use 32GB of ram under 32-bit scenario in the first place tongue.gif they make it seem like you can only use 4~GB and you can use the other 28GB for ram disk. Which if you just use 64-bit you can use all of them thumb.gif

From what I know, Xfast RAM is a RAM disk on steroid. So it's aimed at anyone who needs a RAM disk, 32bit or 64bit OS. The extra features of this utility (as per version 2.0.9) are:

1- Can indeed map and make available RAM beyond the 4GB limitation of a 32bit OS, but confined to the RAM disk only. So if you have a 32bit OS with 8GB of RAM, the OS will only "see" 4GB, but Xfast RAM can create a 4GB RAM disk with the unused RAM left.

2- Can emulate a "ready boost" partition mapped to the RAM disk to accelerate your magnetic hard disk drive, just like an SSD would do. If you already have an SSD boot drive or a small SSD acting as a ready boost drive, this option is useless to you.

3- Option to automatically move your memory pagefile to the RAM disk. 1 click in the Xfast RAM interface, reboot and you are done. No messing around with windows config.

4- Option to move temp and cache of Internet explorer and Firefox to the RAM disk. Again, 1 click in Xfast RAM interface, reboot and you are done. No messing with windows config.

5- Option to move both (and independently if you like) the system temporary files and/or the user temporary files to the RAM disk. 1 click in the ... you know the drill.

6- Option to backup the RAM disk when you shut off the PC to keep the content intact and ready to use at next boot. If you use the ready boost option, a UPS is highly recommended to prevent the lost of the RAM disk content.

You can assign any free drive letter you want to the RAM disk. You can choose the size of the RAM disk. Apparently, it can support RAM disk size of 8GB for 64bit OS and 32GB for 32bit OS. I benchmarked the RAM disk with Diskmark and got 9800MB/s sequential read with a i5-2500K OC to 4.7Ghz and 8Gb of RAM @ 1866 10-9-9-28 1T (ASRock Extrem4 GEN3). Got very similar result from another Ram disk utility. Xfast RAM is the most versatile RAM disk utility I've ever tried.

NOTE: Beside the obvious gain in speed (huge gain with Photoshop apparently), this utility is highly recommend to SSD users to limit / reduce write operations that will degrade your SSD.

NOTE2: With 8GB of RAM in my PC, I've created a 1GB RAM disk and it's more than enough for the vast majority of scenarios. I've only encountered limitation with archiving utilities such as Winrar and 7zip. Both app have the option to specify the temp folder of your choice if you need to create archives larger than the maximum capacity of your RAM disk.

So I just got an ASRocks mb and I am reading about this virtual disk. Is there any benefit to saving this data on reboot? I don't really care if my temp files are saved.. or cache files, but maybe I am missing the point.

Hey Folks,
I'm a flight-sim, (FSX), hobbyist and over the years, have invested thousands in high-resolution scenery, aircraft, mesh, etc., etc. The system runs great at max 4096 texture resolutions. However, when I fly over some of the high-resolution add-on airstrips with a high-end/high-resolution aircraft, it doesn't take long before I begin getting the Windows warning tones that I'm about to run out of usable memory; OOM.

I pause the flight and minimize it to the task-bar by the 4th or 5th warning, I can maximize the flight and continue after waiting a minute or two. However, I'll start getting the warnings again within a minute of flight and if I don't repeat the process, the sim will close and the OOM error alert will open.

This is something I've been dealing with for some time now and I've done all the 'common' suggestions that are posted about this issue, (most are Page File assignment variations). I have reason to believe FSX is building up adding the temporary files as it they're generated replacing the ones that were no longer needed with the latest.

I'm not sure, but this may be a typical action of the sim and not a bug. Therefore, I was considering using Asrock's XFAST RAM software which I typically have disabled since I installed the board over a year ago.

I have 2 sticks of 1600Mhz x 8GB ram O/C'd to 1866Mhz. Of course, I have a liquid cooled i7-2600K o/C'd to 5Ghz, (FSX is notoriously "CPU intensive"), and have no trouble maintaining 32FPS in the most demanding scenarios. I just run out of available memory under the circumstances I've mentioned above.

My system info is below but in short, I have four, internally connected drives. One dedicated SSD for the O/S, One dedicated SSD for the FSX sim, and One SSD for other FSX add-ons that require a lot of space, (some of which have been 'moved' there with Steam Mover). Of course, I have a 1TB HDD/7200RPM HDD that supports the O/S software and another 1TB HDD/7200RPM that's connected via an external eSATA port. That drive is where I reassigned as the default location of the O/S Temp. & dmp. files.

I'll probably have enabled, (and likely updated), the Asrock XFast Ram tool before, (and "if"), I get a reply to this post. However, I would still appreciate any thoughts/suggestions someone may have about the use of that XFast Ram tool to try and solve this OOM issue.
Thank you,
Rich
PS: Please note that reducing any of the FSX settings pertinent to Texture or LOD resolution, Shaders, etc., is not an option I'm willing to resort to. I'm very aware of the fact that such changes would likely solve the issue. However IMO, doing that would be like buying an expensive 200mm - 800mm zoom lens but never zooming it beyond 300 or 400mm because it triggers some problem in the camera, (if you can see my point).
