  • Reducing both pagfile.sys and hiberfil.sys in Windows 7

    - by greenber
    I recently used Defraggler to consolidate my free space areas on my D: drive preparatory to using Disk Manager to break my drive into two areas, one as my "data area" for Windows 7 (normally on my C: drive) and to experiment around with Windows 8. The Defraggler program works so well I ran it on my C: drive and I ended up with a lot of free space both on my C: drive and my D: drive. I was very happy. And then I woke up the next day and I've got virtually no free space left, something like 8 MB on my C: drive and about 3 GB on my D: drive. I then ran Wintree (which gives a nifty graphical representation of disk usage) and found I had a large page file and a large hiberfil. So I temporarily turned off hibernate and reduced the page file size to 2000megabytes and then rebooted so that both would take effect. It had no effect on the C: drive or the D: drive. That makes no sense to me. What caused the free space on each drive to disappear, why doesn't the page file size being reduced and the hibernate file being turned off free up disk space to either the C: or the D: drive? Would it make sense to delete the two files in question and, if so, how do I go about doing that? Safe mode? Thanks. Ross

  • explanation of RAM specs, and what do I need for a Gaming rig

    - by ewok
    I am looking into upgrading my custom built PC's RAM. I use the machine mostly for gaming, but I don't really know a ton about RAM, so I wanted to ask a few questions. The research I've done tells me there is a negligible increase in speed for anything above 1600 MHz. is this true or is it worth the extra money to go higher? Other than drawing more power from the PSU, is there any real difference in performance with different voltages (1.5V vs 1.65V)? most of the kits I've found in the 2x4 1600 range have a CAS latency of 9 and timing of 9-9-9-24. For a significant increase in price (usually about 1.5x), I can get either 8 or 7 and lower timing. Is it worth the cost? What I am looking for here is someone to give a good explanation of what the different specs represent, and how that relates to the performance of the machine. Specifically, I'm looking for what specs I need to focus on for a good gaming rig. I am NOT looking for a "buy this, it's the best RAM" without an explanation of why. The information will be much more valuable as it will allow me to make my own informed decision. As they say, give a man a fish, he'll eat for a day. teach a man to fish, and he'll eat for the rest of his life.

  • Does adding 1066Mhz DDR3 SODIMM to a 1600Mhz FSB laptop make sense?

    - by Alain Pannetier
    My previous laptop had 4x4GB 1066 Mhz DDR3. My new laptop instead has only 2x4GB 1600 Mhz DDR3. Using dmidecode I gather my FSB is set to 2300Mhz. Max Speed: 3800 MHz Current Speed: 2300 MHz 2 questions: Can somebody confirm I can safely add two "old" 1066Mhz modules to my new laptop before I treat myself to faster DDR3 modules? I understand this should not slow down the faster 2 1600 Mhz DDR3 modules. Correct? If this is of any relevance, I'm running Linux Mint Maya.

  • Calculating RAM Performance? Example: DDR3-2133 CL9-11-10-28 1.65V vs DDR3-1600 CL10-10-10-30 1.5V

    - by user1131467
    How do you calculate the relative performance of PC RAM? For example, what is the relative performance of the following: G.Skill Ripjaws Z 8 x 4GB Kit, DDR3-2133, [email protected] G.Skill Ripjaws Z 4 x 8GB Kit, DDR3-1600, [email protected] If it's relevant, when they are used in a top of the line ASUS Rampage IV Extreme motherboard and Intel i7 3960X? By performance, I mean relative: read latency write latency read bandwidth write bandwidth Please include working. (I mean how did you arrive at the figures based on timing and DDR3-speed)

  • I cannot connect to home server after a few hours

    - by Iago
    I have an old PC and I decided to revive it. A LAMP (for my own use) and a P2P server (torrent and e2dk). My old PC is an AMD Athlon XP (1400 MHz) with 384 Mb of RAM First of all I installed Ubuntu Server 11.10, SSH, FTP, SAMBA and LAMP. With this configuration my home server works well, with no problem. Then I went to the P2P server and I tried rTorrent and then uTorrent Server Alpha. And here is my problem. After a few hours (maybe 10 hours, or maybe 30 hours) with the torrent app running (rTorrent or uTorrent) I lose the connection to my home server. That is, I cannot access via ssh, I cannot access the apache server, etc. but I can ping the home server. It seems that the server freezes and all I can do is reboot the server physically. So, I have two questions: What is the problem? and How can I solve it?

  • Frequency of RAM

    - by Vignesh Palani
    I have a very old system hp compaq dx2080. It had 1gb of RAM. I recently bought a EVM DDR2 1 GB PC RAM which had a clock rate of 667Mhz. I have dual booting windows 7 and 8. When I installed it, windows 7 was still using the older 1gb. It showed as 2 gb available and 1gb usable in system properties. I searched around and found that I can change it to max in the msconfig. I did so. I set it 2048. Still, it was using only 1gb. When, I switched to 8, it was using the 2gb. Now, for my question: My system only supported 553Mhz and 667Mhz RAM. In the BIOS, I saw that the new RAM was showing as 800Mhz. Rechecked using speccy and cpu-z. It showed different values between the two. The RAM is labeled as 667Mhz over it. No mistake in that. But, am I missing something? Please help. And, can I continue using it? My point again. There are only two slots.

  • Java JRE: Setting default heap size

    - by AndiDog
    I'm having trouble with Java on a virtual server, it always gives me the following error: # java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I first solved this by using the CACAO virtual machine (of OpenJDK, by putting it first in jvm.cfg), but then I run into problems with my web application (Play! framework based, gives me nasty LinkageErrors). So I cannot use that VM. Instead I'd like to just use the normal server VM and set -Xmx128M by default. How can I do that? Related: this question

  • VirtualBox cannot start a virtual machine on Windows 7

    - by Zan Lynx
    Note that this question is mostly so others can find this information. I ran into a problem recently with my Fedora-14 virtual machine running on a Windows-7 host with VirtualBox. VirtualBox could not start the Fedora virtual machine, but it could start a Ubuntu virtual server machine that was configured for 512 MB of RAM. The Fedora-14 machine was configured for 2 GB of RAM. The Fedora-14 machine had been working a week ago. What had I recently changed...? Answer to follow.

  • What does motherboard RAM slot colors mean?

    - by totymedli
    I always saw that the motherboard RAM slots are colored in pairs, but never know what does it means. I just put the 2 RAM in, and after a few tries it always worked. But after I tried to install a third one it always throws me a blue screen of death. Is there an order how should I install RAM to the borad? What does the colors mean? Does they indicate performance boost opportunity or are they just a guide for installation?

  • Would Windows 8 may increase the Cap of more than 2 GB?

    - by Pisaro
    I have a old Laptop Dell Latitude D430 that I just upgraded to Windows 8. The Ram that I have installed is 2GB (Max Ram that this laptop can handle) but I am wondering if by installing windows 8 can help also to increase the cap of the total Ram that the laptop can handle. I know that some laptops have a cap of RAM by the Bios but I am wondering if any of you know if by installing a new OS can actually change this? thanks, Robert

  • How to check use of userva boot option on Win 2K3 server

    - by Tim Sylvester
    I have some 32-bit Win2K3 servers running an application that fails now and then apparently due to heap fragmentation. (Process virtual bytes grows, private bytes does not) I do not have access to the source code or build process of this application. I have modified the boot.ini file on one of these servers to include /userva=2560, half way between the normal mode of operation and the /3GB option. Normally it takes weeks to reach the point of failure, but I'd like to see right away whether this has actually had any effect. As I understand it, this option limits the kernel to the remaining address space (1536MB instead of 2048), but does not necessarily give an application the extra address space, depending on the flags in the application's PE header. How can I determine whether the O/S is allowing a particular application, running in production, to access address space above 2GB? Additionally, what's the best way to monitor the system to ensure that the kernel is not starved for address space, and more generally how should I go about finding the optimal value for this setting?

  • Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM

    - by magneticMonster
    I'm running a Java data import process on a 32-bit Ubuntu 10 PAE kernel machine. After running the process for a while, the oom-killer zaps my Java process. After some Googling and digging through docs, it looks like the system is running out of LowMem. I started the process for the third time and am watching free -lm show me Low: 464 386 77 with the free value (77MB) slowly decreasing. Why am I running out of lowmem and how do I increase it? Some details: $ cat /proc/sys/vm/lowmem_reserve_ratio 256 256 32 $ free -lm total used free shared buffers cached Mem: 32086 24611 7475 0 0 24012 Low: 464 407 57 High: 31621 24204 7417 -/+ buffers/cache: 598 31487 Swap: 2047 0 2047

  • How do I find the source of soft page faults?

    - by David Robison
    I have Windows 7 x64 computer that according to Performance Monitor has 70,000 page faults / second when idling. That's seems like a lot to me (every other computer I check has basically 0 page faults / second when idling). If I use Resource Monitor or Process Explorer to check hard faults, I see that they are basically 0. So all the page faults are soft. Normally, soft page faults are not a problem, but I suspect they might be causing issues for this computer given there are so many. I would like to identify what programs are causing the soft faults. Are there any tools that exist the display the number of soft page faults for each process?

  • Computer crashes twice/thrice before booting into windows

    - by Adil Malik
    I need help. i built a PC, and it behaves very strangely. When i press the power button, the lights come on, fan maxes out, HDD spins, bios shows up etc and then it immediately crashes (powers down) before booting into windows. Then it powers on automatically and this time boots correctly. Sometimes there is just one failed boot and sometimes it takes 2 such boots to correctly start the computer. This unexpected shutdown never happens once it has booted in windows, just between the windows logo and bios menu. Any ideas?

  • Is there way to enable 4 GB RAM in 32-bit Windows OS?

    - by Wahid Bitar
    I upgraded my PC to 4 GB RAM and I get only 3 GB. Windows 7 32-Bit consider that I've 4 GB RAM but didn't use more than 3 GB. Someone told me that MS Windows 32-bit doesn't support RAM larger than 3 GB. So please is there any way to make my OS "Windows 7 32-Bit" support more than 3 GB RAM ? *`Note: I can't move to 64-bit because I've many program doesn't work with a 64-bit OS. Edit:: I tried what Mr. Wonsungi advised me but whenever I check this option: Enable support for 4 GB of RAM I get the following error: 'Cannot access to the registry key HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-11d1-A9F0-00AA0060FA31}.' There is no "CLSID" in my registry, I don't know why!.

  • Computer slow after installing 32GB RAM

    - by John Gilmore
    I'm currently running very large network simulations for my PhD research, for which I need lots of RAM. I have a Core i7 2600K processor with a Gigabyte GA-Z68AP-D3 motherboard, running Windows 7 professional 64bit. I bought the system with 8GB (2x4GB) DDR3 1600 MHz Corsair Vengeance RAM and the system ran like a dream. I'm planning to upscale my simulations so I removed the 2x4GB RAM and installed 4x8GB DDR 1600 MHz Corsair Vengeance RAM. When I rebooted the system, boot time was much longer than usual (10 mins just to get to login screen). After logging in, the whole system was unresponsive. I tried playing some games (Bioshock 2), but it was unplayable. I've not had this problem before and I have an ATI Radeon HD 5850 graphics card, so that's not the problem. The only thing that's changed is the RAM. I've looked through the specifications of Windows, my motherboard and my CPU and they all state that 32GB of RAM is supported. Does anyone have an idea of what's going on? Any help would be greatly appreciated.

  • Lenovo ThinkServer TS130 1105 - does 32/64 depend on RAM?

    - by Ecnerwal
    Just got in a Lenovo ThinkServer TS130 1105 (Xeon E3-1225V1) and a (new, sealed, holographed, looks legit) copy of Windows Server 2008 32/64 (standard) to run on it for a pretty lightweight job (currently handled, adequately, by a terrifyingly old Optima P4 running Windows 2000 server - really lightweight, but long-past-due for replacement, without any particular need or excuse for server 2012...) The 64 bit disc sits there and does nothing. The 32 bit disc boots. I haven't spotted any mention of this in the TS130 Manual (I have now combed it, and find no mention of a need to populate in pairs - a preferred order to populate in, yes, but no mention of pairs being required) but I begin to wonder if it's due to the fact that the 4GB RAM suppled with it was a single DIMM, rather than a pair. Better for upgrading, but perhaps requiring an upgrade (or sidegrade) right away to install the x64 version?? Anyone know? I tried the 64-bit DVD on a desktop with an AMD Athlon II X4 635 processor which normally runs Windows7 in 64 bit, and it booted up just fine.

  • memtest86+ crashing on server

    - by user148723
    we have a few DELL 1950 servers. 1 of this servers has CentOS6.3 and its randomly rebooting so I suspected it was hardware. (no log generated) the other 4 servers do not randomly reboot. We passed memtest86+ on the 5 servers, and on 3 of them memtest86+ crashes (displaying an odd and colorful screen, like if a video card failed) Although I tested old memtest86 (not +), and all servers did not crash. I also tested other RAM testers utilities, no tool failing. have any of you guys experience this? thanks

  • Failing RAM, or something else?

    - by Thanatos
    I have a IBM Thinkpad T43, currently running Windows XP. Programs were crashing, XP was blue-screen-of-deathing, (more than usual) - it was basically unusable, but I couldn't get any informative error out of XP. I booted Ubuntu off a thumbdrive, which made it to the desktop, but as soon as I started to try to do anything, X segfaulted, along with several other services, followed quickly by kernel warnings and a kernel panic. I'm currently running Memtest86+ on this machine, which is spitting out numerous errors. (16k over 3 passes, and counting) The failing areas are numerous, and look something like this: 0001055da4 - XX.X MB, etc. The addresses that fail seem to cluster around 0-20 MB, 250MB, and, more rarely, 750MB, 1000MB, and 1200MB. However, a lot (but not all) of the failing addresses that I've seen end in XXXXXXX?da4 where the ? is a 1 or a 5. The machine has two sticks of RAM, one 512MB, one 1024 MB, the 512MB mapped to the lower addresses, the 1024 MB stick following. Is this indeed RAM failure, or should I consider other things before purchasing more RAM?

  • Default maximum heap size -- Ubuntu 10.04 LTS, openjdk6-jre

    - by sachin
    I just installed openjdk6-jre on Ubuntu 10.04 java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu1~10.04.1) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode) Every time I run "java" I get this error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. This can be solved by specifying a maximum heap size and running "java -Xmx256m" But is there anyway to permanently fix this error (i.e. set the default heap size to 256MB so that I do not need to specify the max heap size every time I run the command)
