Cosmin3 Posted January 2, 2011 Share Posted January 2, 2011 (edited) I've been using Windows 7 for a few months.I's better than Windows XP with a few exceptions.For example the caching from memory manager.It's designed to keep last used programs in memory.It's good if the programs take less Ram and are used (restarted) frequently.But if the programs are big and are used rarely it's worst.For example on my computer I have 2 GB RAM.I use VirtualBox with 1 GB memory set to a virtual machine. And I use it for a long time.So, meanwhile, most of that memory goes to pagefile.I close VirtualBox and I have to wait dozens of seconds until all the data from pagefile is copied back to physical memory.By the way, on my computer the pagefile is not fragmented and is on a fast drive.Anyway the cached memory from such programs is totally useless because I start other big programs and the memory manager flushes it.I know that a quick solution is to buy more Ram.But still I want to know if there is a way to (partially or completely) deactivate this memory caching...Thank you in advance for any reply.

MagicAndre1981 Posted January 2, 2011 Share Posted January 2, 2011 You mean Superfetch. You can disable the Service but this slows down the PC (boot process, switching between apps, application start) Link to comment Share on other sites More sharing options...
Cosmin3 Posted January 2, 2011 Author Share Posted January 2, 2011 (edited) I deactivated it in services.msc and restarted Windows.Seems to work a little better now. My HDD is not used continuously anymore...Thank you.I heard before about Superfetch but I only knew that it (pre)loads previously started programs at Windows startup. But I didn't know that is responsible with programs caching after startup.A question: Prefetch from Windows XP was completely replaced by Superfetch in Vista/7 or is still used...?Later edit: I said it works a little better but I'm not so sure that the programs aren't cached.For example now I'm using rt7lite to add updates to Win 7 DVD:Task manager says that I have 1056 MB cached and 47 free...

MagicAndre1981 Posted January 3, 2011 Share Posted January 3, 2011 Please download and run RAMMap, run it and save the data as a RMP file. Zip the RMP file and upload the zip, please. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted January 3, 2011 Share Posted January 3, 2011 From your data I can see that you have 6GB RAM, but in the picture you have 2GB RAM. Also remove AVG and Comodo and see if the usage is better. Some downloaded files and program files (firefox, skype are in the cache). Link to comment Share on other sites More sharing options...
Cosmin3 Posted January 4, 2011 Author Share Posted January 4, 2011 Very, very strange:- I have only 2 GB;- AVG and Comodo are not installed. I never even heard of "Comodo"...- Firefox and Skype are installed but on a different Windows (XP), on a partition that is hidden when I boot in Windows 7. In 7 I have only Opera and Yahoo Messenger.Are you absolutely sure that you're looking in the data from MY computer..?'Cause I searched the words "AVG", "Comodo", "Firefox" and "Skype" in this data file and I couldn't find them...

MagicAndre1981 Posted January 4, 2011 Share Posted January 4, 2011 have you send me the wrong link? send it again. Link to comment Share on other sites More sharing options...
Cosmin3 Posted January 4, 2011 Author Share Posted January 4, 2011 I don't think I sent you the wrong link and, even if I did, what are the chances that it would be a data.rmp file also ? Anyway I never used RamMap until now and I never sent such files to anyone.I downloaded the file from the link and I searched for those names: nothing.I uploaded the file on megaupload and I sent you a pm with the new link.The checksum file is like this:; Generated by WIN-SFV32 v1.0; (Compatible: Total Commander 7.56a)data.RMP 58BC0DC5 Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted January 4, 2011 Share Posted January 4, 2011 sorry, I opened the wrong file You have an issue with "driver locked"Driver Locked: These are pages that have been locked in physical RAM by a driver. This can be done for small/temporary purposes like I/O or for larger/longer allocations like RAM drives or other large locked memory reservations.So a device driver called a function to lock memory and for Windows to have it in RAM all the times.I can see that you use Kaspersky. Which version do you use? Is this the 64Bit version (I see that you installed it to C:\Program files (x86) which contains 32Bit application on a 64Bit Windows)?And with 2GB RAM, you should use a 32Bit Windows. A 64Bit Windows only makes sense if you use more than 3GB.sorry for the confusion. Link to comment Share on other sites More sharing options...
Cosmin3 Posted January 4, 2011 Author Share Posted January 4, 2011 sorry, I opened the wrong file No problem.You have an issue with "driver locked"So a device driver called a function to lock memory and for Windows to have it in RAM all the times.Ok, but which program does that...? VirtualBox, Kaspersky...?I can see that you use Kaspersky. Which version do you use? Is this the 64Bit version (I see that you installed it to C:\Program files (x86) which contains 32Bit application on a 64Bit Windows)?I bought Kaspersky Antivirus a few weeks ago.I couldn't find a 64bit version but, from what others say, 32bit version should work fine on 64bit Windows.And with 2GB RAM, you should use a 32Bit Windows. A 64Bit Windows only makes sense if you use more than 3GB.I'm using 64Bit because for some time I'm thinking of buying another 2 GB. Link to comment Share on other sites More sharing options...
