PCI memory Controller

Hi all
How do I get rid of this yellow question mark in Device manager
Says
PCI Memory Controller no drivers loaded.
Running K9N4 Ultra F with Sempron 3000 CPU 1 gig Ram
Win Xp Home new copy and sata 160 gig drive Seagate.
ATI video 1300 card PCI express
Is this cause the raid drivers are no installed?
Thanks

What ram are you using?

Satellite Pro A200-1MI - Need driver for PCI memory controller

I have the Toshiba Satellite Pro A200-1MI(PSAE7E) having a problem with PCI Memory Controller on my notebook.
When I go to Device Manager it shows question mark in the tab Other Devices and when I go there, it's yellow ?(question mark) and !(exlamation mark) at PCI Memory Controller. I took and downloaded all the drivers from your site:
http://eu.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp?service=EU
for XP but I am not sure what type of drivers do I have to install for PCI Memory Controller, is it bios driver or something else? I just need to know what to install to overcome that problem with my Device Manager and PCI Memory Controller.
Thanks in advance!

Hello akibono
I presume you have installed clean WXP on your notebook and now you want to install all drivers, tools and utilities. Am I right about that?
Anyway, after WXP installation you must install all drivers, tools and utilities in specific installations order. After doing this everything should be OK and every hardware component will be properly configured.
Please install all stuff as follow:
WXP
Chipset driver
Display driver
Sound driver
Modem driver
Storage manager
LAN driver
Touchpad driver
WLAN driver
Toshiba Assist
Flash Media driver
Webcam driver
Hardware setup
Controls
And so on
I hope everything will be OK.

2nd Request - PCI Memory Controller for ThinkPad T500 2081-CTO OS Vista 64bit

Evidently the PCI Memory Controller driver is not installed on my ThinkPad T500 2081-CTO OS Vista 64bit and shows up as an error when running the Lenovo System Tool Box.
Searching this forum I found one psot as follows BUT thisis for a T-200 laptop.

You need the driver for Intel Turbo Memory. Only Windows Vista can use Turbo Memory, so we only have a Vista version for the driver:
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67820
Is this driver appropriate?
Do I need the PCI Memory Controller driver .. and if so where do I find it for my laptop?
Thanks.
Solved!
Go to Solution.

I would suggest that you forget about turbo memory. Intel quit talking about it and they have not released a driver since 2009. That is 2 years before service pack 1 was released. I ran tests and I was never able to measure any improvement with a card installed. As far as I am concerned, it is just something else to break and interfere with other components.,

(865PE Neo2) - Memory Controller Problems ???

Hi, I've been having problems with my RAM. I've run MEMTEST and found that my RAM continually failed test #5 (64 Block move). However, I pulled the RAM and tested in a friend's computer..... and it passed without any problems..... I went back to my computer and continually changed the BIOS setting until I finally got something to work....
What I did, was change the DRAM Freq from 400 down to 333. And it seems to be stable..... (The RAM was meant to run at 400)
The people at Corsair offered to replace the RAM, however, because both sticks produce them same problem, and because it works at 333 but not 400, and because it fails test #5 and not any other test, then they think the problem lies somewhere other then the RAM. And at the stage, i tend to agree.....
Now someone suggested it might be the Memory Controller..... I have no idea what that means..... but it sounds plausable.... Eitherway, I believe it might have something to do with the Motherboard..... And I was hoping someone here might have an idea on how I can either test it, or fix it.....
Thanks a bunch.....
My SYSTEM Specs are.....
MoBo : MSI 865PE Neo2-P (MS 6728 ver.2)
CPU : Prescott 3.2

Hi,
I've tried the RAM sticks individually, as well as 1,3 and 2,4..... And it doesn't make a difference.
I've aslo Disabled Spread Spectrum
And I've also tried all these setting, plus more.... @400Mhz
2-3-3-6
2-3-3-7
2-3-3-8
2.5-3-3-6
2.5-3-3-7
2.5-3-3-8
3-3-3-6
3-3-3-7
3-3-3-8
all without success..... And what i mean, is that I still get error#5 in memtest. And ALWAYS the error occures in the 92%-96% portion of the test.....
HOWEVER, When I drop the DRAM Freq to 333.... No problem..... All is fine..... Even at 2-3-3-6
Unfortunately, I doubt I will be able to test any other DDR400 memory in my system, but it would be interesting to know the results.....
I also find marginal confort knowing this problem is a bit 'common', however, i would find MORE comfort solving the problem :-)
Thanks :-)

Code 12 on [VIA PCI to PCI Bridge Controller]

Hi,
I am having an issue while setting up a new pc with the following setup:
MotherBoard: MSI P4M900M3
CPU: Pentium Dual Core e2180
Memory: 2 * 1Gb Kingston DDR2 667
Harddisk: Hitachi SATA 320Gb Harddisk
OS: Windows Professional (upgrade to SP3)
Using the build-in video and audio card provided in the motherboard.
After I installed the OS, i find a yellow exclamation mark in [Device Manager] -> [System Devices] -> [VIA PCI to PCI Bridge Controller] (there are 2 of these entries with the same problem) indicating the problem is :
This device cannot find enough free resources that it can use (code 12).
If you want to use this device, you will need to disable one of the other devices on this system.
I have tried removing the 2 entries and let windows detect it automatically but the same problem still show up.
I have only 1 harddisk, 1 dvd drive and 1 floppy drive connected to the motherboard so i wasn't expecting such conflicts to show up.
Please help.

Have you tried to delete them, and let's windows to re-detect them?
Have you done >>Clear CMOS Guide<<?
What mainboard you have? {P4M900M3-F or P4M900M3-L}

K9vgm-v problem with pci ide controller card

My problem is with a promise ultra100 tx2 pci ide controller card that I got with a western digital hard drive a year or 2 back. I can plug the card in with no hard drives attached to it, boot into windows, update the drivers, etc. but when I plug either of my hard drives into the card, it goes to a black screen directly after the screen the promise controller brings up after the main msi bios screen.
It's my understanding that this problem is caused because the ide controller card can't inject its bios into the option rom of the motherboard. I've tried disabling as many other features that I can in the bios to clear up some space in the option rom, but so far no luck. I made sure I have the latest MSI bios, but I am 1 or 2 revisions behind on the promise controller card bios, because I don't have a floppy drive and I can't get any bootable cds to work.
If need be, I can get a new ide controller card, but I would rather not, because this one works just fine, and I am pretty short on cash. I am also worried that this same problem will happen with other controller cards that I pick up. Any advice on how to get this thing working?
P.S. - is there any way to get this board to boot from a USB key? My only options in the bios for booting to USB are USB-FDD, USB-ZIP, and USB-CDROM.
-MSI k9vgm-v
-phoenix rev 1.2 (I think. Can't remember. Whatever liveupdate says is the newest)
-AMD Athlon 64 3200+

That means reboot cycle?
Have you tried with more powerfull PSU?

USB-FDD, USB-ZIP or in HDD area.. depend how will be detected your USB key.

Check the exact version. Latest version is 1.6, if there is an conflict that raid card unable to register property like(No enough Space to copy PCI Option ROM or similar) a new bios can help.

There is no driver for memory controller with A64 (nforce3/4) as stated earlier .
You see this in the memctrl.inf for UDP 5.10 , driver pack for nforce 3 and backwards down to nforce 1 .
Memctrl is only added to the 5.10 package for backward support to nf2 and lower as this is a unified driver package and
the memory controller is at chipset level on the motherboard that resides in the external northbridge on nf2 chipsets and lower .
What you see is just a vendor/machine id description and is just as it should be .

Windows 7 driver for PCI Simple Controller

I installed the Lenovo Windows 7 Professional upgrade on my R400 (7443-CTO) from Windows XP Professional. The ThinkVantage tools repeatedly shows I need a driver for the "PCI Simple Controller". I have been unable to find that driver on the Lenovo support site. Any assistance to help resolve this issue would be appreciated.
Solved!
Go to Solution.

To create shortcuts or folders under the startmenu in Win7 you can rightclick "All Programs" under the startmenu. Then you can choose "Open" or "Open all users". If you choose "Open" you will be able to change the startmenu for the current user account only and when you select "Open all users" you can change the startmenu for all user accounts on the computer. The startmenu in Windows is basically just folders and shortcuts stored in a folder on your computer. The startmenu for all users are stored under "C:\ProgramData\Microsoft\Windows\Start Menu" and for the current user under "C:\Users\<useraccount>\AppData\Roaming\Microsoft\Windows\Start Menu"
So let's say you want the "Thinkvantage" folder under the Windows startmenu where it should normally be after installing Lenovo toolbox and then the shortcut for Lenovo Toolbox under that folder. Then you can rightclick "All Programs" under the startmenu and select "Open all users" from the context menu. You should then see a explorer windows with the folder "Programs". If you open the "Programs" folder you will see the same contents as you see under the "startmenu -> All Programs". Since this is the area for the common startmenu for all user accounts there might be some more entries under the startmenu compared to what you see in this windows. By selecting "Open" instead of "Open all users" as explained above you should find the rest. So when you rightclicked, selected "open all users" and then doublecliked on "Programs" then you can rightclick somewhere in that window and choose "New -> Folder" from the context menu. Then you can give the folder the name "Thinkvantage". Then open the "Thinkvantage" folder and create a shortcut for Lenovo Toolbox. After you have done these steps you should find the Thinkvantage folder under "All Programs" and then the shortcut for Lenovo Toolbox under the Thinkvantage folder. This is how you can easily change the startmenu in Windows to add, remove or change entries under "All Programs".
Normally after installing Lenovo Toolbox it should be under "All Programs -> Thinkvantage" and not sure why that is not the case for you, but then you can add it manually like explained above. When i installed Lenovo Toolbox a shortcut and the Thinkvatage folder was created under "All Programs" during the installation. Also if you install the "System interface driver" and "Hotkey feature set" you can start Lenovo Toolbox by pressing the blue thinkvantage button on your computer. Unless you already installed "System Update 4.0" i would recommend to do so. System Update will find the drivers and software from Lenovo for your computer and give you a list where you can select those you want to download and install. System update will then download and install the drivers and software you selected and you don't have to download and install each one of them manually one by one. It will save you a lot of time. You can find system update for Windows 7 using the link below.
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-73695
User Access Control is a new feature of Windows that started with Windows Vista so therefore you won't find it in XP. Only Vista and Windows 7 got UAC.
Yes it's a bit late over here I'm sure i will enjoy the weekend and hope you will do the same.

PCI USB2 Controller card conflicts with network card

I've installed a PCI USB2 controller card since my motherboard (IWill K266-R) only has support for USB1. However, the card seems to conflict with one of my network cards, because traffic on the internet-connected NIC is very slow, and often drops completely. Traffic to and from the other (local) NIC seems to work fine, though.
I have tried moving around all three cards in different PCI slots, I think I've tested almost every possible combination by now. I've also tried disabling as much as possible in BIOS, such as onboard sound, serial and parallel ports etc. I've tried lowering the FSB.
For now, I've removed the controller card, and is using the USB1 ports on the motherboard instead. This is very frustrating, though.
Does anyone have any suggestion on what I can try next? I've browsed forums, both this and others, but I haven't found any more hints on what to try. Could there be some setting in Arch that could affect these sorts of things?

"I guess the ATA100 card will work fine correct?"
If you mean large drive support, it may provide that or may require a firmware update to do so. You should check the manufacturer's web site for specifics. All ATA-133 cards do provide 48-bit LBA for large drive support. I'd return the Ultra ATA-66 card to the eBay seller, although many refuse to pay for return shipping, even when the mistake is their own, either through ignorance or deliberate misrepresentation. In cases such as this, it's sometimes more cost-effective to swallow the loss and keep the incorrect part.
"Will adding a jumper apply for a ATA100 card as well? I'll need a blue and gray ribbon correct?"
If you use an 80-conductor ribbon cable with color-keyed connectors, set the drive configuration jumper to CS and connect the drives to the cable as you wish (in terms of physical placement in the computer). If the ribbon cable doesn't have color-keyed connectors, set the jumper for the device connected to the end connector as Master and the drive (if any) connected to the middle connector as Slave.

Temperature Monitor Alert:Memory controller heatsink Results!!!

Hello all...
I have a question about the Memory Controller Heatsink sensor in the temparature monitor and I would appreciate it if you could shed any light in my problem.
Well it was long time since I checked my temperatures on my G5 DP 2.3 so yesterday while I was into some MP3 encoding I heard the fans making alot of noise ,not something unbearable but not the usual silence behaviour I was used to even under heavy load and with the nap off.
So because of that noise I decide to check it with the temperature monitor but nothing unusual came up except...yes you guess it the Memory Controller heatsink.
An alert came up and inform me that the temp was over 75 C/167 F.
The threshold was by default at 75 C/167 F.
Let me add that it's summer here and a hot one at 37 C and the room is not airconditioning,but it was exactly the same one year ago(June 2005)and I never came up with an alert.
Also I have no problem with the rest indications.
So what do you think is it normal or may I have a broken fan?
And finally what is the Memory Controller Heatsink?
Thanx in advance!

The memory controller heatsink is shown, with the associated cooling tubes and fins, in the right-hand photo of the 'back' of the main logic board here
http://homepage.mac.com/jerrycube/jerrycubepix/22601bluebord.jpg
Air is pulled over the back of the main logic board and through the cooling fins, by the fan in a plastic housing, at 90deg to all the other fans, behind the hard drives.
This fan is called "Main Logic Board Backside" by Hardware Monitor in this ancient DP2.0 - and is showing "20%" in 22deg C room temperature. "Memory Controller Heatsink" is at 54deg C.
37deg C is above the specified max. 'Operating Temperature' of 35deg C shown here
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
I think it would probably be advisable to find some way of lowering the temperature of the room the G5 is in...

Resource conflict- pci network controller in slot 09

Dead MS6330 after PCI IEEE1394 Controller install

Hello,
Yesterday I installed a PCI IEEE1394 Controller on a MS-6330 with 1300Mhz Athlon. After installing the necessary software and restarting my WinXP couldn't load. I tried removing and adding the newly installed card, the LAN and video cards. Now as I start the computer the power supply looks fine, all the coolers start etc. but no signal (even BIOS) appears on the monitor, neither does the 'No input signal' message that appears when video signal is absent. Could you offer some solution to the problem?

On-board RAID and PCI RAID controller

Hello everybody,
I am new to the forum. So, please excuse me if that topic was already covered...
I have MSI MAX2-LR (MS-6398E) board. It works just fine, no problem so far. Though I have 2 problems with add-on cards:
1. I was planning to use on-board RAID and additional PCI RAID controller = FastTrack 100 TX2 to cover 6 hard drives into 2 mirrored sets: 4drives one and 2 drives the other.
It doesn't work! I can use either on-board RAID or PCI RAID. As soon as I have any drive connected to on-board RAID, the PCI RAID disappeares. If I have no drives connected to on-board RAID, I can see both RAID controllers, they have different I/O and IRQs, and PCI RAID is working just fine. If only I connect one drive to the on-board RAID, it gets activated on startup, and the other one disappeares. :O
I believe it's a BIOS bug. I wander, if that can be fixed easily????? :D
2. I have a new Matrox Video card = Parhelia. It doesn't work in AGP slot! System doesn't recognize it, and beeps non-stop. I am dealing with Matrox Tech Support on that matter. ?(
Maybe, it's a known issue, and somebody can save me time by telling what's that about.
Appreciate any imput. Have a great weekend.!!! :]

Hey I also have the same Raid card and also the Matrox Parhelia, and I see that you also have some problems with the card I got also problems with the card, but they couldnt help me at theire forums (http://forum.matrox.com/mgaforum/Forum10/HTML/005085.html), I hope we have got more luck here :D

Read/Write PCI Memory

Hi All,
This question may be outside the scope of Java and this forum (appologies if so). However, I'm trying to read/write some PCI memory locations in either Linux or Windows. I'd like to access these locations via Java. Is there any direct method to do this? Is there an API to access more low level hardware? Currently, I can read/write the memory locations with a program called PciTree. So, I know my PCI device is working, and the basic driver for the PCI device is installed.
If this is not possible in Java, I can try C and study the device driver's functionality.

You could write something in C/C++ and then expose methods to Java via JNI. But Java doesn't have built-in support for accessing memory at that level. A third party library may be availble though. Good luck.
