Esxi Ram Issues / Questions

Hey guys so have some issues with the only Vm i am running on this box A virtual Unraid Build
so i currently have Esxi 5.5U2 running specs are as follows:
Mobo: Asus P7P55WS Supercomputer
Cpu: Xeon X3440
Ram: 8gb crucial
Ssd: Raid 0 128gb Vertex 4's (Unraid cache drive)
Hdd's: 5 x 3tb WD Reds
Hdd: WD 250gb Blue - Datastore drive psu:
Corsair TX750 Case:
Norco 4020
Nic: Brocade cna 1020 10GB  - Setup in Esxi with a vm Network to Unraid using Vmxnet3
Raid card: Silicon Image 3114 - For the Esxi Datastore
IBM M1015 flashed to Lsi-9211-IR-8I
I have passed thru the 6 ports on my motherboard to the VM for unraid
My main issue is that i am unable to allocate more than 4GB of ram to the VM. I get all kinds of errors when doing so.
This started after I enabled passthru.
I get this message:
[code]Powering on the virtual machine fails with the error: Invalid memory setting for FPT: memory reservation (sched.mem.min) should be equal to memsize(xxxx) (2002779)[/code]
So i tried setting the memory for the VM in MB and then changing the reservation for to match exactly in the settings. After doing that i get this error
[code]The Execute Storage vMotion for Storage DRS task fails with the error: The available Memory resources in the parent resource pool are insufficient for the operation (2070921)[/code]
I have no idea where to go from here. Any ideas?
I have plans on getting more ram for this machine, but dont want it to go to waste if i can figure out how to allocate more than the 4GB i already am

If I remember correctly the window's paging file is set to a discrete size, believe recomended 1.5 x ram size.  If Bridge is running in 32 bit mode guess you only need 6 gig paging file, but would more do anything?  How large is it, is it on a seperate partition?  Also consider this:
If a paging file resides on a partition that contains other data, it  may experience fragmentation as it expands to satisfy the extra virtual memory that is required. An unfragmented paging file leads to faster virtual memory  access and to a greater chance of a dump-file capture that is free of significant errors.
Is fragmentation a consideration?

  • RAM issues/questions with Bridge CS4

    Hi,
    I've become a little perplexed with Bridge CS4.  I constantly get an "out of memory" error with bridge when working with many large files (21 megapixels) through adobe camera raw, despite having a bullet proof system.  First, some system specs:
    Vista 64-bit
    Intel i7 3.2GHz processor
    12 Gb of 1600Mhz RAM
    Dedicated separate scratch disc
    This computer just freakin rips!
    So photoshop (the 64 bit version) just runs like a breeze, despite vista being its stupid self and taking up about 1.6 gigs of ram just for the OS.  However, I am mainly wondering that if Bridge isn't a 64 bit program (it is installed in the x86 program files. Only photoshop is installed in the 64-bit program files) then maybe it can't utilize the extra ram over 4 gigs?  If so, then it is severely crippled and limited to the 4 gig ceiling shared with the RAM thirsty OS.
    Does anyone actually know and have any answers?  I know the "out of memory" error has long been discussed but never seems to come to some solid conclusions.  And really, there is no reason why bridge should be out of memory on a 12 gig system with 9 of those just sitting free when it say its supposedly "out of memory".
    Any ideas?
    Thanks

  • A question about performance ( ram issue? )

    Small question. I have a Macbook Pro unibody - it has a Corsair Solid State Drive in it. 4 gigs of ram. I have an external hard drive with a few hundred movies on it. Each movie's icon is notated with a picture of a flag where the movie's origin is. Anywho. When I click the HD to look at all my movies, it takes a bit for all of the pictures to load for the icons. Not only that when I scroll up or down some of the icon pics will disappear, then reappear. In other words - it's slow.
    I previously had 8gb of ram in my 17 inch pro (i have a 15 now) - and I don't remember having this problem - but i don't really remember much. My question is - do you think this is a ram issue, an external hard drive issue - as in, it's not super fast, or some other issue. What can i do so when i open this folder up, I don't have serious lag time for the icons to show up? I think it's not a ram issue, i'm guessing it's an external issue - not so much that the external has a problem just that it's now fast, but want to check here to make sure. thanks.

    How are you accessing the external harddrive? Firewire 800 is going to be faster than USB2.0 This I would expect, not RAM.
    A faster connection or a faster external HD I suspect would be the answer.

  • Kernel Panic and RAM issues

    about a week ago I got my first ever kernel panic . This coincided with the mac completely running out of battery due to being on a holiday. Sometimes I can get on without an issue for a while until it shuts down and either tells me there is a kernel panic or it does the three beep black screen. From what I have researched its a ram issue. from memory I have 2x2gb rams installed but it may be 4gb I'm not 100% sure and I cant get on to check. I'm pretty sure its not a software issue as I have booted up on several occasions and deleted things such as Sophos. I'm out of warranty so its up to me to get this show back on the road. My questions:
    If I can startup the computer and have it running for a while before it dies and says is a kernel panic, is it unlikely its a software related issue?
    Is there any possible way of testing for dodgy rams without physically removing one at a time and seeing what happens?
    Is there anything else it could be?
    Can rams cause kernel panics, if so do the panic reports reflect this?
    cheers

  • RAM Issues: 4GB installed, 1GB showing After blinking light

    Hey Folks,
    After doing some research online I found that my recent issue, which has come up in the past, was probably a RAM seating issue. The issue where the Fan begins running loudly at hyper speed. I forced a shut down, restarted up and saw no issue. Shortly there after the issue returned. I forced a shut down once more, but this time was met with a blinking power light.
    I remembered from past experience that it was a sign of RAM issues so I unplugged, unseated and reseated all four of the RAM on my cards. Initial start up was met with same response. In fact it wasn't until the 6th or 7th seating and reseating, and RAM position switch that I got the computer to start back up. (The initial successful start up was with one card and what should have been 2GB.)  I checked the About this Mac.. and saw Memory listed as 1GB 667  MHz DDR2 FB-DIMM. The 1GB threw me off because at that moment there should have been 2.
    Shortly there after I backed some things up and tried reseating the other card with the other 2 gigs in it. This time I was able to start up however the System still shows the Memory as 1GB 667 MHz...
    I did notice a single red light on one of the cards and am curious if this is trying to tell me anything, or if this is an indication of a poor installation. Also looking for any advice on why the computer is not seeing all 4 gigs, and if some of them may be out of service.
    Any advice would be much appreciated, and please pardon my lingo because I'm not sure all my wording is correct.
    Thanks

    Stop beating yourself up over insertion technique. These things get mighty hot and they FAIL.
    If they have a reseller's sticker on them, like Otherworld computing or 1-800-Memory or such, call them and ask for lifetime warranty replacements. Otherwise, think hard about how much RAM you really need and go buy some.

  • RAM ISSUES A215-S7407 - PSAFGU-01V002 SUSPEND MODE ERROR WITH 4GB RAM

    Hi, im having some troubles with my laptop.
    Because it comes only winth 1GB RAM (512MB x 2) i decided to give it an upgrade to 4GB (Max Capcity) according to specifications details on the support site. So i bought two (2) DIMM Modules KINGSTON 2GB 667MHZ, exact model # KVR667D2S5/2G Everything was working fine until i close the lid and it suspend.
    Normally, when i open the lid, it will wake up, and everything will work fine, BUT NOW when it wakes up i have distorted sound and horizontal lines on screen, and sometimes i get a BSOD (BLUE SCREEN OF DEATH) and it restart itself.
    TEST THAT I MADE:
    ONLY 1 DIMM of 2GB  - IT SUSPEND AND WAKES UP NORMALLY (I tested both Dimms 2GB separately)
    1 DIMM 2GB / 1 DIMM 1GB (TOTAL 3GB) - IT SUSPEND AND WAKES UP NORMALLY
    2 DIMMs 2GB  (TOTAL 4GB) - IT SUSPEND AND WAKES UP WITH DISTORTED SOUND AND HORIZONTAL LINES ON DISPLAY.
    It seems like the problem appears only with Max. Capacity (4GB) RAM and only when it suspend CLOSE THE LID (POWER LED CHANGE COLOR BLUE TO ORANGE AND FADES AND COMES).
    With Hibernation, it works fine, the problem is when it suspend.
    It looks that the problem is on the motherboard, maybe a NEW BIOS RELEASE that fix the situation.
    I appreciate if somebody can speak to TOSHIBA SUPPORT DEVELOPER and ask them for an BIOS Update.
    i know that im not the only one with this problem, there is another person that wrote a post "RAM ISSUES" and refers to the same situation, but as i guess, it wasn't solved at all.

    Make sure you install the memory when the light is not flashing, i.e. completly off not sleeping.

  • RAM issues continued

    Hey everyone!
    I was just reading an archived post from around this time last year entitled "Strange RAM issue." I too have had a strange RAM issue and specifically with my G4 PowerBook (15", 1GHz) and OWC. I also wanted to upgrade from 512 to 1GB and could never get the machine to work at 1GB. I am currently in the process of sending back my third consecutive OWC brand RAM to them and they are finally going to send me some TechWorks memory that I'm hoping will work. I just can't believe...every single set of memory they've sent me has tested out "fine" to them either after I sent it back or in the latest case even before they sent it to me. But it never works in my computer and always fails the Rember test.
    Their latest take on it is that the Rember test isn't always reliable and that it's probably a problem with the memory port in the computer in that it won't accept outside (aka non-Apple) memory. What are some people's thoughts on this? Is it possible that the memory port could work just fine with the original computer's RAM and not with new RAM? Is there any truth to Rember not being all that reliable of a test? (If so, why would they have you use it?)
    I'm really getting frustrated with OWC and I was wondering if that's just me or have other people had this same problem?

    APPLE HAS A RECALL for this! READ BELOW AND SAVE SOME MONEY!!!!
    Anyone with these issues needs to see this link. Apple has a recall going for G4 15" AL PBs because one of the two RAM slots die. Mine has been "fixed" twice under this program. There's a number to call to get started. Be forewarned, the person on the end of that phone is not the sharpest tool in the tool box. I had to show him where the recall was on Apple's site and how to interpret it. He had to keep putting me on hold to check with a Powerbook Expert (his title was only Powerbook Specialist). They send you a nice prepaid DHL 24 hr turn around shipping box. First time was great. Second time it came back covered in sticky. greasy fingerprints and the metal around the case screws has been badly scratched. I'm still waiting for Apple to address this but since they found 3rd party RAM in my PB, this is my punishment. FWIW, if you let it go in the broken state too long, bad things could happen. Something from the corrupted RAM wrote to my HD and ended up causing all sorts of issues. A reformat and reinstall was the only cure. Here's the link: http://docs.info.apple.com/article.html?artnum=303173
    A few private repair places on the web get over a grand for this repair. The repair is a complete new main logic board exchange. Big bucks.

  • Creating an Aperture web page from photos the page goes white and nothing displays. Is this a RAM issue?

    I have just purchased an iMac 27" 2.7GHZ running OSX 10.7.4 with 4GB RAM (16 GB has been ordered). I am using Aperture 3.3.2. When I attempt to create a web page from photos the page goes white and nothing displays. Is this a RAM issue?

    I have resolved the issue....turns out that, in my case, running OSX 10.8.1 with Aperture 3.3.2 was what was required! I was running Aperture 3.3.2 with OSX 10.7.x and had this issue.
    I hope this helps someone else as well.

  • X-Fi Xtreme Audio & 4GB RAM issue - latest driver?

    :X-Fi Xtreme Audio & >4GB RAM issue - latest driver?T Hi All,
    Been using an X-Fi Xtreme Audio with 4GB RAM for ages, no issues.
    I purchased and installed a zotac 9600 GT which has GB onboard ram, which works fine, but now my X-Fi has started causing general system instability. (processes using heaps of CPU time whilst apparently doing not much, jerky/slow adobe flash, distorted (slow-motion) audio at random times, etc etc.
    In the support section here it says:
    Audio issue from output from soundcard with computer having 4GB RAM:
    <span class="text">
    Keywords: <font>4GB ram, installation, xfi, x-fi
    Summary: Customers with computers having <font>4GB or above of RAM and are experiencing audio issues, please download the latest driver for your sound card.
    However... When this issue first came up I formatted my primary dri've, reinstalled the OS and downloaded the latest drivers for EVERYTHING. The problem has prevailed..
    It was only yesterday that I tracked down this problem in the support section here, and tried to verify that my driver is indeed the latest. But device manager lists the driver as "6.0.0.209" when in the support section here the downloads are named ".xx.xxxx" or something. How can I confirm that I have the latest driver? In any case, I'm almost certain that I have the latest, and this issue is still occuring.
    I have read in other forums that on other varients of my X-FI card, the latest drivers have not solved this problem either.. sorry I cant be more accurate than that.
    For now, I have solved this problem by simply removing 2GB of ram from my PC. Obviously, I'd like to find a solution and put the other 2GB back in!
    Thanks in advance for your help!

    Could DanielK please mod this as well, so we can try them. Or Daniel, you could you please tell me how you modified the previous drivers from auzentech as I dont know how these CL drivers work and are modified. What is the inf in these drivers, and if you could tell me the deviceID?s of all the x-fi models, or atleast for x-fi xtreme music as it is my modell. Thx in advance!
    EDIT:
    I have modified the drivers, was not so hard after all. Im uploading the file now, which should have support for all X-FI cards thanks to Daniel's great job with the earlier version.
    Upload finished in 4-5minutes. I will post with link soon to rapidshare!

    Hey Daniel,
    First it would be helpful to know exactly which iBooks you're talking about.
    CPU speed, screen size, OS and RAM installed.
    So how do you know the all three have onboard RAM issues? Does system profiler just show the 0 slot as empty?

  • V11 firmware RAM issues...what worked for me

    I think everyone that has upgraded to the v11 firmware has by now noticed the RAM issues in the v11 firmware for the N95 (At least in the European generic firmware).
    The cause of this problem appears to be the 23 or so programs the firmware installs into the phone memory that are all related to the "Search" application on the phone.
    I uninstalled them all and the RAM problems went away.
    To get rid of them go to Tools > Application Manager and uninstall everything you see related to search.
    While I was at it I got rid of Snakes, the System Rush game and the settings and welcome wizards.
    Note that this will remove the Search application from your phone entirely so do so at your own risk.
    An alternative is to move it to your memory card if you wish.

    The problem you are having is a DNS issue.
    Somewhere along the line your DNS address(s) became deleted from the network System Preferences for your 'active' connection (e.g Airport). It probably was set to default to your local (home) router.
    This basically means that safari can not find the web site you attempt to load, so it waits for a very long time.
    You can add in the DNS address(s) by either going to System Preferences / Network and selecting your active network connection / DNS tab. OR you can go to Safari Preferences / Advanced and then click the "advanced" button which will take you to the System preferences panel.
    The DNS server is provided by your ISP in most cases, or you can use the "Open DNS" servers at 208.67.222.222, & 208.67.220.220.

  • Green frames on timeline. RAM issue? GPU issue?

    Hi guys!
    Have anyone experienced that?
    These green frames at timeline. After that my Program Monitor freezes and crashes and soon after Premiere too. There is no wat out. It freezes and doesn't close.
    I am using Premier Pro CC 2014 at Windows 7 Home Premium.
    Another thing: Adobe recommend 8GB of RAM and I have these 8GB and constantly apears RAM low memory, sometimes it crashes just after the message. It can be a low RAM issue? So why Adobe recommend 8GB if it's not enough?
    Maybe GPU? It is a GT540m with all drivers updated and working well on non-Adobe softwares.
    Thanks!

    Thank you for your prompt answer.
    I have just read the article you linked over.
    Had read one of 'em earlier but they're interesting to understand how Mavericks work, I still have some points of interrogation.
    If we consider the figue on how memory compression works, it seems like it is all good but it still doesn't account for why I am using more memory for the same runing processes. I mean, in my case it does not free up memory in the general sense, it litteraly eats memory and THEN frees it up when needed. And why devices use more than twice the memory than others.... this is nuts to me.
    I forget to mention a few things. A friend of mine has the exact same configuration of mbpr. And here is what's crazy, he doesn't seem to use any comparable ram amount than I do, even when I lauch it all out on his mac he never uses more than 5gigs....although we had no internet connection at the time so I assume that might be the reason why ram usage was less important, I really don't know.
    I know activity monitor ram monitoring comprises file cache too but when I run the 'top' command in terminal, it is kinda the same, just a bit lower let's say the 1 to 3 gigs of file cache that is taken into account in activity monitor and not in temrinal.
    Anyways, I guess I'll will keep faith in apple technology as I can't pretend there is any performance drop that I was able to observe.... even with a bad taste in mouth that something is wrong that I can't point my finger at

  • WiSM Design and Testing Issues / Questions / Queries etc......

    Hi all. Heres hoping you can help........
    I hope you can grasp the following description of the test network I have. I admit a diagram would have been better but it's hard to send a whiteboard over the web : )
    I am currently in the process of designing and testing out a wireless solution and am having a few issues / queries. I have a 6509 with a Wireless Services Module (WiSM) installed in slot 3, one Cisco 1240 AP on a remote LAN and a DHCP server on a remote LAN (not the same as the AP)
    I am using LAG on controller 1 with port channel 1 and native VLAN 20.
    VLAN 20 is 10.1.1.0 / 24
    The management interface has IP address of 10.1.1.10
    The AP-manager interface has IP address of 10.1.1.11
    VLAN 11 is 128.88.1.0 / 24
    The service port has IP address of 128.88.1.10
    The Cisco 1240 AP on the remote LAN is picking up a IP address via DHCP (from a remote DHCP server) OK and can route to both the aforementioned VLANs 20 and 11.
    Issue/Question 1
    I can ping the management interface locally on the 6509 and also remotely from the AP so all looks OK there however I cannot ping the AP-manager locally or remotely.
    Is this expected behaviour? I would expect that if I can ping one I should be able to ping the other or is the AP-manager interface not routed and only used in some way to create the LWAPP tunnel>
    Issue/Question 2
    As previously stated the AP is picking up and IP address but it is not being passed the Option 43 parameter from the DHCP server (not yet ruled out the DHCP server as the cause of this). Due to this I have amended the DNS entry of the management interface (10.1.1.10) to CISCO-LWAPP-CONTROLLER as a last resort. With a console on the AP I can see that the AP tries to join by the "%LWAPP-5-CHANGED: LWAPP changed state to JOIN" output but then get;
    LWAPP_CLIENT_ERROR_DEBUG: spamHandleJoinTimer: Did not recieve the Join response
    LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain.
    Is this related to the fact that I cannot see the AP-Manager interface on the network?
    Issue/Question 3
    I have chosen to hard code the IP address of the Service port rather than leave it to DHCP. I am more comfortable having static addresses for management. However, there is no option for a default gateway for the service port.... If I try to get round this by applying a static route via the CLI on the WiSM controller to point traffic out via 128.88.1.1 on VLAN 11 this seemingly overrides all routing on the controller and causes my management interface (10.1.1.10) to fall off the network. Is the routing table applied "en masse" to the Controller? If so this surely means that to use the Service Port you have to be on the local LAN segement?!?!
    Thanks for reading my ramble and heres hoping you can shed some light on my "niggles" !

    Hi
    I am having exactly the same problem.
    Getting the same error message "No more AP manager IP addresses remain."
    I'm deploying 200 AP's that will connect to 2x WiSM (4 controllers) in 2 seperate C6k Chassis
    (Controller 1a & 1b = wism 1, 2a & 2b = wism 2)
    I have had 1 out of the first 5 AP's physically connected, come online and register with Controller 2b (btw: this was not the master controller, it should not have registed with 2b). All others fail with the same error message as above.
    I have all Management and AP-Manager interfaces in the same vlan/subnet as my AP's.
    I place a console cable onto the failed APs and see the AP cycle though the motions of trying to find the controllers, download new software code from a random controller, then it reboots, gets DHCP assigned, then get the "No more AP manager ip addresses remain" and then issues a "Reload requested by LWAPP CLIENT.
    Then the AP does the whole cycle all over again.
    Not sure why the AP's don't register with the controllers when they are all in the same vlan.
    I have a couple of extra questions.
    1. what address do you bind to the dns entry cisco-lwapp-controller.localdomain, is it the management address or AP-Manager address ?
    I have bound it to the Management address for WiSM 1a.
    Also I have 4x controllers (2x WiSMs, 2 controllers per WiSM). Do I just bind controller 1a's address or do I have to put 4x DNS entries into my DNS server for all my controllers?
    2. DHCP option 43, Do I place all 4x management ip addresses in the option or do I put in the AP-Manager Ip address?
    I followed this guide but was still a little unsure http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp125304
    2. This final question is more around Dynamic Interfaces for my 4 controllers once I get the AP's resisted,
    Do I have to set up a dynamic interface ip address on every controller?
    e.g.
    Ssid = data, VLAN=10, VLAN10=10.0.0.0/24, I will bind AP's 1-8 to VLan group 10.
    Do I have to setup 1 dynamic interfaces per controller in the 10.0.0.0 subnet, taking up 4 addresses ?
    And if I only have to set up 1 or 2 dynamic interface, how does this work if the controller fails?
    Cheers

  • Another RAM upgrade question

    Hi everyone,
    I know there seems to be lots of RAM upgrade questions here but hey thats what forums are for.
    I'm looking to upgrade my macbook's RAM it's currently got 2GB (2x1GB)
    Is it possible to purchase 1x4GB and put that with one of my current 1GB sticks to create a total of 5GB?
    I would be interested to know if this is possible or if anyone has tried it.
    Thanks in advance
    Scott

    This will work if your MacBook is late '07 or newer.

  • Desktop RAM upgrade questions

    Hi, I have hp elite m9000t series desktop with 2 GB(1 x 1GB) ram and as per the specs and research in hp website it can support to 8gb. RAM is of DDR2-SDRAM (pc2-5300 / 667 MHZ) type. I have 2 more slots open, so guess that can add 4gb(2 x 2gb) of ram. Question is 1) do i need to buy the sam ddr2 667 mhz ram or can i go to higher speed models? 2) is it compatible to have 2 slots with 1 gb  each and another 2 slots with 2gb ram each? 3)what is the recomended RAM for window7 better peformance? i am planning to install VMware to do other OS like linux, etc.. given that i may need more RAM. Please suggest me on the memory upgrade..I am seriously looking towards windows7 release date, i am very much disappointed with vista, cant wait for windows 7.
    btw, i am planning to upgrade to 64bit windows 7 professional, currently i am running with home premium 32bit.

    It's best to install RAM which is just like the one you have right now, i.e. pc2-5300 / 667 MHZ. In fact, I would recommend using RAM from the same manufacturer as the one that is currently installed. Each slot should have the same amount of RAM. So I suggest you use 1+1 or 2+2 rather than 1+2. Since you'll be using VMWare(hope your processor supports Virtualization), I suggest you go for 2+2.
