DDR2 is seen as single channel???

Thanks in advance for all of your help!
I have a K9N Neo-F MB AM2 socket with a GB of OCZ DDR2 667MHz that is seen by the bios as single channel. Is there a jumper that I need to have connected or is there a bios setting that I need to change? If it is a jumper which one is it?
Thanks,
elitt2

Do you have 1 stick or 2?
If it is just one stick then it will only operate at single channel. If you have 2 sticks then make sure that they are in the first 2 slots closest to your CPU (the slots should be colored differently) and then you will have dual channel.
If this does not help then you will need to give us more info about your comp. Like BIOS version, PSU ratings, etc.
I agree unless the RAM is a single then it run's in single channel or IF you have both it could be that you put the wrong dimms which is also another possibility to run in single channel but not in dual channel...Refer to the mobo manual about the RAM setting. (Should be Dimm 1/3 or Dimm 2/4). Gd luck

Trouble with Mobo running on single channel

I bought a pair of identical 1GB DDR2 PC2-5300 (667mhz) chips for my P4M890/900M2 motherboard and Windows 7 and my bios are only registering 1gb. CPU-Z is showing that I'm running on a single channel only, from what I've looked into, this problem seems to occur only if the chips aren't identical, but mine are; what gives? Anyone have an idea as to whats wrong?

There is no mention of dual channel for this Via chipset:

Hey smoothdurban,
I've seen Brad's code, and trust me, it's worth the effort to let him help you get it up and running - it's definitely the most ideal way to solve this problem. However, as Brad said, there are multiple ways to tackle this - both interactive and programmatic - so in the meantime, I'll take a second to detail one of the interactive and sure-fire ways to find the average of data between two points on a single channel.
We'll use"Flags." Set up your VIEW graph exactly as you did on your original screenshot, using Band Cursors to approximate the beginning and ending X-values representing the range you want to examine. Next:
1. Click the "Set Flags" button () that is a part of your 2D Axis System. Note that you can hold down the Shift button if you ever decide you want to do this on more than a single curve at one time.
2. Select the "Flags: Copy Data Points" button that enables after Flags are set.
3. This creates new channel(s) in the default (bold) group in the Data Portal that contains only the Flagged data.
4. Select DIAdem ANALYSIS.
5. Select Statistics » Descriptive Statistics.
6. In the Channels input, select the newly created channel containing your Flagged Y-Data.
7. Ensure that the Arithmetic Mean parameter is set. You can preview the data and the result in the dialog before pressing OK to execute the calculation.
You may have noticed that in the Descriptive Statistics calculation, one of the parameters that you can set is the range of channel rows to operate on - so, if you know the row numbers of your beginning and ending X-values, you could just simply run the Descriptive Statistics calculation and use this parameter to operate on a row subset of your original channel instead of the entire channel.

Hi,
I am trying to Set/Get Volume level of Input device which has only single channel but no master channel, then it fails to retrieve the kAudioDevicePropertyPreferredChannelsForStereo and intermittently kAudioDevicePropertyVolumeScalar for each channel. But this works well for Output device.
So is there any difference in setting/getting the volume of input channels?
I am pasting the downloadable link to sample.

Thanks in advance.

That works but the the game will not be in full screen, it will have an empty strip at the bottom.
I actually found out what's the problem. I traced the stageWidth and stageHeight during resizing event. I found out that when it first resized, the stage width and height were the size with the notification bar. So when I pass the stage into startling, myStarling = new Starling(Game,stage), the stage is in the wrong size. For some reason, I can only get the correct stage width and height after the third resizing event.
So now I need to restart Starling everytime a resizing event happened. It gives me the right result but I am not sure it is a good idea to do that.
And thanks a lot for your time kglad~I really appriciate your help.

How to do a single channel DAQ using NI-DAQ driver software with a PCI-MIO-16XE-10 card

Hi,
I would like to find out how I could do a simple one channel Data Acquisition from a signal generator using the NI-DAQ driver software with a PCI-MIO-16XE-10 card.
I have written some test problem but even when the signal generator is turned on/off I get back some weird values.

Currently Unavailable Message for a Single Channel

Has anyone had this issue with a single channel? The new FSC HD (584) that just came out last week worked for 1/2 a day then it started showing Currently Unavailable. I had a technician out a few days later and he checked signal strength, changed all the connections at the splitter on every line and the channel started to show up again. Two days later it went back to Currently Unavailable.   After 2 hours on the phone, an hour tech visit, an hour on online chat, researching all I could, etc. they have no clue what to do and now I have to wait for a technician to come out again in 7 days!!!!!   Gotta love Verizon!
I can't believe that there is no record of another customer having this issue in their tech support databases and someone can tell me something other than unplug the connection and plug it back in.
Solved!
Go to Solution.

The technician changed out all of the connections into and out of the splitter. We also reconnected everything along with way (at the router, to the TVs and from the wall plates, etc.).   It worked fine for a day or two then went out again on all of the TVs. Then this morning the channel is appearing again (without doing anything), but it's just a matter of time until it goes out again.   My question is I could understand a connection issue if it were all of the HD channels, but why on just this one (the newest one released about a week ago, doesn't happen on the previously released HD channel BET).

Adding a single channel to my service?

I am hoping to get an answer from someone in Verizon. Can I add a single channel to my current lineup. I just switched from Comcast and realize now that I don't get the NHL network. I don't really want the entire sports package for $15. Can you add single channels? Thanks

Answer is no, you have to either upgrade to a higher tier or subscribe to the sports package. You're basically asking for ala carte channels (as walt said), while that is most of us would want, it just is not available.

Similar channel into single channel

Dear All,
Is there any way to merge the multiple similar channel to single channel without flattening layers.
If pantone reflex blue 3 times is there means i need to merge it into single reflex blue channel.
Pls help..
Thank you,
Joe

Yes spot channel only and in Same document itself.
And the above script need to run in Extend tool script?. Coz by this script there is no changes happening.
By using Apply image can merge only two channels at a time. And after merged into a single channel source channel also remains.
For ex, Pantone Reflex Blue 1
Pantone Reflex Blue 2
Now i need to merge into 1. so after Merging by using Apply image
Pantone Reflex Blue 1 2
Pantone Reflex Blue 2 (But this is to be automatically deleted after merging, which is not possible by using Apply image)
By using the script this needs to be recover
1) In channel options
Color indicates - Spot Color
Color - Reflex Blue
Solidity - 0%
In same way i have taken the separation in different area of my image with same spot color.
2) If process color are taken as spot channel that also need to merge with process channel (CMYK)
Color indicates - Spot color
Color - C100%
Solidity - 0%
If this is option selected in this channel to be merge with Cyan process color channel.
By using Apply image option i used to give Multiply only and Opacity to 100%. Same need to apply this script. Pls help..
Thank you,
Joe

Capture single channel in c++

Hi,
I'm trying to write a simple C++ routing (Visual C++) using the NIDSA functions that generates a sine wave and captures the response data.
I can generate a sine wave using NIDSA_configure_source(), but I can't figure out how to get the response data.
I tried calling NIDSA_configure_capture_buffer() and then NIDSA_read_capture_single_chan() but then I get an "Unknown Error" from NIDSA_read_capture_single_chan(). (Error code = 0xffffd5d0)
Sample Code:
rc = NI4551_ConfigureSource(1,0);
// configure capture buffer
rc = NI4551_ConfigureCaptureBuffer(numMeasurements);
// read single channel
rc = NI4551_ReadSingleChannel("0", numMeasurements, pResult);
rc = NI4551_ConfigureSource(0,0);
I don't know if I've got the correct functions to generate the sine wave and capture data or if I'm even calling them in the correct order.
Is there any sample code out there??
Thanks!

Hello,
You have specified a resource descriptor for the source task but when you are calling the capture commands you have not set up an initialize function that tells the program what board to use. For instance try using the NIDSA_init and then use that session to pass to the other function calls such as NIDSA_configure_capture_buffer() etc. I have attached some example code that reads from the board and demonstrates the analog triggering capabilities of the board. I hope this helps. Please let me know if you have any questions after exploring these resources.

Multiple Endpoints Single Channel

I am working on a project, that requires instancing of our
flex application. One idea that I came up with was to allow for
multiple urls to access the same data based on several variables.
One key components for this idea to work is being able to use
multiple endpoints with in the same channel in my
services-config.xml file.
Right now this is what my channel setup looks like.
<channels>
<channel-definition id="cfamf"
class="mx.messaging.channels.AMFChannel">
<endpoint uri="
http://admin.mydomain.com/flex2gateway/"
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
<serialization>
<instantiate-types>false</instantiate-types>
</serialization>
</properties>
</channel-definition>
<channel-definition id="cfamf"
class="mx.messaging.channels.AMFChannel">
<endpoint uri="
http://user.mydomain.com/flex2gateway/"
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
<serialization>
<instantiate-types>false</instantiate-types>
</serialization>
</properties>
</channel-definition>
</channels>
Ideally I would prefer it to act like this.
<channel-definition id="cfamf"
class="mx.messaging.channels.AMFChannel">
<endpoint uri="
http://admin.mydomain.com/flex2gateway/"
class="flex.messaging.endpoints.AMFEndpoint"/>
<endpoint uri="
http://user.mydomain.com/flex2gateway/"
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
<serialization>
<instantiate-types>false</instantiate-types>
</serialization>
</properties>
</channel-definition>
</channels>

one AP will only serve a single channel per spectrum. If you have multiple SSID they can be on the same channel with no issue, so long as you're not running more than 4-5. After that you start to cause issues inside your own network.
If you absolutely had to run them on different channels, you would need multiple AP to accomplish that.
But as I said, you shouldn't need to.

Actually I have already tried a few things you suggested and got as far as the DAQmx Write vi. The error at the DAQmx was a buffer error indicating i needed to set it to 2 instead of the default of 1. Tried using the DAQmx Input and Output Buffer vi to change buffer, with no luck.

How to access single channels of multichannel acquisition?

I want to access single channels of a multichannel acquisition in the Getting Started Analog Input.vi
The purpose of this is to analyse i.e. do Min-Max or FFT on the individual channels. Can somebody help me to unbundle the data? Why does AI Read give Scaled Data while in other vi Waveform data?

Hi,
Getting Started Analog Input.vi uses AIRead.vi to read data from your hardware.
1. This is from the help about AIRead.vi:
"scaled data is a 2D array that contains analog input data in scaled data units. The data appears in columns, where each column contains the data for a single channel."
So to access the single channel you must use "Functions->Array->Index Array.vi" to get data from your 2D array. All you need is to wire your 2D array to this VI and the specified number to the "column" input node.
2. To change the Data type of array you receive from hardware you have to right-click on the AIRead.vi and choose any of 4 options (Binary Array, Scaled and Binary Arrays, Scaled Array, Waveform) from "Select Type" sub-menu.
Good luck.
Oleg Chutko.

Dual and Single Channel Mode

Talking about dual channel and single channel. Is it a theory or is it really a big significant difference in performance between the two? Just curious

Hi Richard,
Thanks for the speedy reply. I'll go tinker around a little more and see what I can do with this board

Is it possible to execute Single Channel read of AI channel too quickly?

When executing single channel read of volts on 16XE50 in VB6 it seems to return an errornous result if too fast. Increase the time between reads and the result is correct. I need to scan single channel quickly for short period to check a trip point and stop some motion. Any clues?

Check the Zout of your signal source. Any stored charge on the amp inputs needs to be bled off trough your source. If it is higher thatn 1kohm, the settling time of the amp is higher than that guaranteed for maximum accuracy.
NI recommends 10kohm or less, with 1kohm for guaranteed accuracy. You may have to buffer the output of your signal.

Softing profibus OPC PROFIusb, PROFIBUS USB Interface, single channel

Hi,
Is there anyone who has experience with this Profibus interface?
Softing profibus OPC PROFIusb, PROFIBUS USB Interface, single channel or, the PROFIboard PCI Master/Slave
Would it work with NI OPC server or we have to use the Softing OPC server?
Thank for any feedback,
Andras

Hello kaush,
you also should be able to talk to these devices from LabVIEW through direct DLL calls (call library node). Preconditions for this are well documented driver DLLs and some spare time for understanding and implementing the DLL calls. I'm not aware of a direct LabVIEW interface for Profibus boards from Softing and Siemens, but it might be worth contacting these vendors. At least Softing might have something available.
If you need to focus on development time, you also may consider using a Profibus DP board from NI in combination with a PA bus coupler (e. g. from Pepperl&Fuchs). The NI board is developed and manufactured by Comsoft, who is well known in the Profibus market, and it comes with an easy to use LabVIEW API.
Compared to OPC a direct communication with the Profibus board provides much better performance and it's much less error prone, so I can understand your preference here...
Kind regards,
