Readyboost Vs Pagefile Vs RAM
Aug 2, 2009
I'm running Windows 7 x64 with a Quad Core and 4GB of RAM. I've enabled Readyboost on two USB devices of 2GB each I had laying around: a SanDisk Cruzer Micro, random read speed is 5341 KB/sec, random write speed is 3068 KB/sec. And a Kingston FCR-HS219, random read speed is 3412 KB/sec, random write speed is 3739 KB/sec. Not much, but should suffice to give it a try.
While booting, I saw and improvement. But the thing is I have my computer on 24/7 so I don't care that much about boot time. And I don't see a lot of activity of these devices once is turned on. Specially over the pendrive.
Is it because I have > 2GB RAM? Or is it because they are too small?
Would I benefit if I create a pagefile over one of these devices instead of Readyboost?
How can I "measure" this?
Is there a guide regarding Readyboost and USB devices?

The flyer that came with this month's PCA included a tip to utilise a blank USB flash drive for virtual memory. When I go to Properties/ReadyBoost on the USB drive, it says "This device cannot be used by ReadyBoost"Then it says "ReadyBoost is not enabled because the service responsible for ReadyBoost (Sysmain) has been turned off on this computer. An administrator can turn the Sysmain service back on"When I searched, including Microsoft website, there is no recognition of the term Sysmain.

I have a new Notebook, an LG X140, with Windows 7 Home Premium ... activated as Genuine.It only came with 512 MB of RAM so I decided to use ReadyBoost and a 4 GB USB Drive to add more RAM.I selected "Dedicate this device to ReadyBoost" which selected 3851 MB. It only actually created an extra 2 GB of RAM. I believe I understand why there was only 3851 MB available and why it only could create 2 GB of RAM from that. so that isn't so much of an issue for me.I then used a 1 GB SD Chip which is ReadyBoost Compatible and added that to ReadyBoost the same way, hoping that I could push it to 4 GB of RAM ... however my computer still only shows 2 GB of RAM. I have tried swapping different USB Drives and SD Cards but with no success, I can't seem to get my computer to recognize any more than 2 GB of RAM.

I know memory can help save some battery life since it decreases the load on your CPU, and I know Readyboost acts like memory, but I also know USB drives can drain your battery. So my question is, would Readyboost help with battery life or drain it since its a USB?
Aka when I'm running off battery and I want the battery to last as long as possible, should I plug in my USB to use Readyboost or just keep it out?

I have been running build 7260 for awhile on my Asus notebook (see system spec) and so far have not had too many issues with it. Since I have done several succesive upgrades: Vista Business > Windows 7 build 7227 > Windows 7 build 7260 I have noticed some bugs creeping in (apps and games are crashing periodically or not loading correctly, gaming performance could be better). I attribute this to the string of successive upgrades.
I am going to wipe the drive and do a clean install of either the 32 or 64 bit RTM build in the next few days as it becomes available. One of the main goals is to increase performance with both applications and games. I use this laptop for work doing web development and heavy photoshop and graphics intensive work. I typically have many applications open at once using quite allot of system resources.
For this project I am going to:
A: Add another 2gb of ram to bring the total from 3gb to 4gb, or
B: Add a fast 16gb sd card to the system for the ReadyBoost feature, probably using around 6 to 9gb for this feature
For me to add the extra gig of ram it becomes more necessary to install the 64 bit build. If I use the 16gb sd card for ReadBoost, I can probably stick with 32 bit. None of my apps are currently 64 bit anyhow so I am not sure 64bit is the way to go right now.
I would like to hear people's thoughts on this and what others experiences have been especially using ReadyBoost on systems with over 2gb of memory..

I just came upon the concept of using readyboost with my computer since I usually run quite a few programs in the background while I'm gaming. I know it wont help much but just a little increase in performance is better than nothing.
I was just curious how much memory can be used on 1 flash drive?
I just bought a 16 GB Sandisk from Best Buy and when I used Readyboost with it the cap was 4 GB. I wasn't sure if the drive I bought wasn't designed to go higher or my USB port couldnt handle it. Then I wondered if the file format the drive was in was capping it so I can confused and thinking of buying a better one possibly designed for the readyboost.

Readyboost is NOT virtual RAM from a flash drive.Readyboost is NOT RAM at all.Readyboost is a cache used by your hard drive.Basically it copies stuff you normally use to the speedy Readyboost cache, where it can be used faster.Readyboost give an all round performance boost, and is more noticeable with older, slower hard drives. The more you have, and the faster it is means more boost.Readyboost yields the most with small file browsing, boot up time, windows operations, and some programs you use.I have 20GB of readyboost, I got that instead of upgrading my HDD to a SSD or hybrid.

Why does Windows 7 say my 32gb sandisk SDHC 4 is not suitable or does not have the caracteristics for readyboost. Is there anything I can do to change the cards caracteristics so that it will work with readyboost?

Has anyone tried ReadyBoost on a virtual Windows 7 machine on a Mac running VMWare Fusion?
I am running Windows 7 on a Macbook Pro with 8GB of RAM and the Virtual Windows machine really slows everything down globally. I have tried configuring the Windows VR with 2GB, 1.5GB and 1GB of RAM. Configuring the virtual machine with more than 2GB of RAM really slows down the Mac. Hoping that ReadyBoost might improve things.

I have a new 8 GB memory stick and it passed the readyboost test - initially. But I wanted to dedicate the device to readyboost so I reformatted to NTFS (was FAT32 initially) and now all I can get is "This device cannot be used with Readyboost". I have tried a command line test that gives me a read speed of 4.8 MB/S which according to the specs I have seen is fast enough for Readyboost.

I heard that the pagefile uses a lot of space on the ssd and they were right, I reduced it to 800-900mb on my C drive and kept it at system managed on secondary drive. What is the recommended minimum page file size? I have win 7 ultimate x64, 16 gigs ram and my C drive is a 240 GB Kingston HyperX 3k

I like a clean notification area, and one thing that's always bothered me is the "Safely Remove Hardware and Eject Media" icon for my ReadyBoost flash drive. I don't understand why it doesn't ignore all ReadyBoost devices in the first place. Any fix for this that doesn't involve disabling the function altogether?

The files pagefile.sys and hiberfil.sys are 8GB and 6GB accordingly. Are they important? Can I delete them or at least reduce them?

I don't fully understand how all this works yet, and I'm not sure if I can disable this and still expect it to run smoothly! Some places I looked said that with anything over 4gb of ram, I really wouldn't need it, but others said keep it for sure..

I was wondering what's a good size for a Windows 7 pagefile partition? I have Windows 7 installed on my primary drive (OS) and decided to make a 7GB pagefile partition on my secondary drive as I heard it is better to have the pagefile on a different hard drive. I have 6GB of memory installed if it makes any difference.
Is 7GB enough? I noticed the partition already gets filled up so I had to disable that annoying "hard drive disk space is low" balloon notifications that kept popping up.. people are getting away with having no pagefile so I figured 7GB would be more than enough?
I should add that I am not experiencing any blue screens of death or any problems despite the notifications popping up.

Ok so I was trying to install dell quickset which doesn't work no matter what I do since I upgraded to 8gb or ram and installed a ssd. The main problem is I don't have the pagefile turned on so windows won't boot and safe mode boots but only has 240MB of ram and it so full you can't run anything.I have no system restore points. All I need to do is undo the max memory setting. Tried last known config, running msconfig in safe mode, bcdedit.

I have 64-bit Windows 7 running on drive C.
w/ Readyboost enabled (if this matters)
Is it possible / feasible to move my pagefile to my 32-bit (D) drive?
I googled but couldn't find an answer.

Ever since I changed my RAM modules, Windows always allocated more space to the pagefile. When I had 4GB of RAM, the advised size of the pagefile by Windows was 6GB. I now have 8GB of RAM and Windows recommended size for the PF is 12GB. So I set a fixed size of 12GB for the PF and didn't let Windows manage the file by itself. I'm about to get 4x 4GB of RAM for a total of 16GB. And I think it would be really exaggerated to allocate 16GBx1.5=24GB for the pagefile, especially because my system is on a 60GB SSD.
I want to keep a pagefile so please don't advise me to disable it. This is my workstation and believe me I will use all of the 16GB of RAM. My question is: what is the size I should give to the pagefile to avoid any problem (like app crashes)? Is there a way to see in Windows how much MB or GB is currently used by the pagefile? --> That would be a good way to assess my needs.

how much ram I would need to buy to turn off the windows virtual memory? And should I buy ECC or non registered memory? Would 8 gigs of dual channel memory be enough? Also,is it ago to have to sets of dual channel memory (4 x 2 gigs DDR3-1600mhz)?

I run Windows 7-64 bit Home Premium and work on encrypted containers with TrueCrypt. I'm afraid that such sensitive information (including passwords) may be unencrypted on pagefile.sys or hiberfile.sys. How can I securely delete both of these files? I know there's a method in Windows 7 to delete pagefile.sys at shutdown but I heard from different sources on the net, this is unreliable and does not in fact SECURELY delete the content inside pagefile.sys.

My biggest folders are seemingly Network Service and AppData. My OS is on an SSD with 60GB, I have another 1TB SATA and a second 60GB SSD as well. If I were to create these two folders in the second SSD, and make them point there, would this cause any issues? I am trying to re-enable my pagefile because it is currently set to 16MB and I can't create a full memory dump unless I set it back to the original 8GB. I only have 4GB free on my SSD, and it is not enough. The other SSD is empty and entirely available.

I bought a PC with a quad-core system with 16Gb RAM, a 128Gb SSD C: drive and a fast 1Tb D: drive. I just discovered that I have an 18Gb C:pagefile.sys and started wondering about the pros and cons of having this paging file on my SSD C: drive. Given that I have 16Gb RAM, I could probably get away with no page file at all. I could certainly manage with the pagefile entirely on the "traditional" D: drive. Are there any guidelines on pagefile placement in the SSD era?

I had an additional Windows installation for testing purposes, on a different partition and now I want to delete everything associated with it because I need some free space.
Although I managed to take ownership and delete the Windows folder and few others, I can't delete System Volume Information and the pagefile.sys file.
System Volume Information - I can't get "ownership" of the files in the directory. Although I'm listed as an "owner" of the directory with "full control", when I check "Replace owner on subcontainer and objectes" I get "Access is denied" and then "Stopping propagation of the owner leads to an inconsistent state..." I think I came across this before, but I have no idea what to do. I also get "access denied" when I try to change the read-only attribute of the directory.
pagefile.sys - when I right click on it, the security tab says "The requested security information is wither unavailable or can't be displayed"
note: I can't format the partition

In my first partition I have windows xp, and in the second partition windows 7.Is it safe to use only one swap / pagefile from only one partition (first one where resides windows xp)?My pagefile size is set to be in the first partition and at fixed size (minimum 4096 Mb maximum 4096 mb).Or should I make/move/user a swap file from the second partition (windows 7 partition). Far as I know from my benchmarks the hardisk is faster in the first partition (first 20 GB), that would be the xp partition, fast in the second one (from 20 to 50 gb) after this the speed is decreasing.I am using windows xp because Photoshop and some games seem's to be far more resposive and faster than in windows 7, and I use windows 7 for internet related & other stuff
