Can't get Dual Channel mode to work

Hello,
I have a pair of 512MB DDR400 ram sticks (listed in my sig).
The Memory Slots are arranged like this:
1 2 3
[cpu] | | |
I put each stick in slot 1 and 2 and no workie, still Single Channel Mode.
I put a stick in slot#2 and #3, no workie.
I put a stick in slot#1 and slot#3, no workie.
Is there something else that I'm missing or did I just buy the wrong memory for dual channel operation? It was not a matched set, but it is the same no-name brand of memory I bought from newegg.com. They both have the same 3225804T-5 marking on them...
They are supposed to be 2.5CS and that is what my bios is set to. I don't have any special settings in the bios that I know of..
Let me know if you have any ideas or if I need to post more information.
Thank You!

Not sure about this but is that motherboard based on the Nvidia nForce2 400 chipset?
What does the manual specs say?
If it is then it doesnt have 2 memory controllers and can only do single channel.

That your mobo?

[VIA Series] Can't get dual channel on P4 3.2 HT MSI PT880 Neo ?????

When I boot up it says 64 bit single channel, this is confirmed by CPU-Z.
I bought 2 PQI 3200 512 DAH Dual channel memory sticks (Identical) bought in a single package ($159.00) when I got this Mobo and machine , originally Fry's installed them in slot 1 and 2,javascript:void(0);
noidea
I've moved them to slot 2 and 3 which accordinhg to the hand book and what I've seen in forums should enable the dual channel mode. Still single channel. I've set the bios to force dual mode and still I'm in single mode. I don't know if this is related but anytime I've ever tried to use top perfromance or best performance settings in BIOs it won't reboot and I have to clear the CMOS so no overclocking for me...... I have the latest Bios version 2.0, just updated that from 1.90 todayand all the latest VIA drivers etc.

I wondered why Sandra said my memory was choking my processor. Its 800 FSB and HT is enabled. In addition, I have frequent BSOD issues, IRQ less or not equal, pagefile in non paged area, I just want to play some battlefield without getting kicked to desk top or boot.....
Other question, sitting here typing this and my CPU temp is 46 C.
Any help would be appreciated, I'm not sure what I've missed and I'm a noob at this stuff, would increasing the voltaqe help????

The online manual for the PT880 NEO-FSR says slots 1 and 3 are used for dual channel.
I don't know about the Via chipsets, but the Intel chipsets need the DDR voltage set to at least 2.65 for stable operation.

Can't get WDS Relay mode to work.

I'm trying to create a wireless network between 2 houses across from one another. Basically, I want to use a SlingBox to access a DirecTV receiver attached to a large satellite dish. I have 3 new Airport Extreme 802.11n base stations and if I could get them linked together this should work really well. One base station in my current house, one in my old house connected to the SlingBox, and one somewhere in between acting as a relay.
I've tested this set-up with the 3 base stations in one room and I just can't get it to work. No matter what, the base station that's set to WDS Relay always has a blinking amber light. The main base station and the remote base station both have green lights. Also, once relay station has a blinking amber light, I can hardly ever access it from the Airport Utility. I usually have to completely reset it and start all over again. When I have been able to access it, the error messages have been either a WDS error saying no peers can be found or an "Ethernet Unplugged" error, even though I have it set to participate in a WDS network.
Has anyone been able to set up a network using an airport base station set to WDS Relay yet? If I can't get this to work, will I get the same results just using an extended Airport network rather than a WDS network, setting the 2 additional base stations to extend the network?
Thanks,

Oh, and how do you like the SlingBox? Are you
running the Mac OS version?
I love my Slingbox, which is running the MAC OS version ......but
It was working fine until I swopped my D-Link wireless router for an Airport Extreme. My Slingbox was reaching my WLAN via the ethernet port of an Airport Express, but since "upgrading" to a X-modem and Airport Extreme set up I have hit trouble.
I can set up the Airport Express to join the Airport Extreme WLAN (e.g. for Air Tunes), but not to extend the network.
If I try to set up the Airport Express from a factory re-boot to extend the network with Air Port Utility, it just seems to crash the Airport Extreme.
Alternatively if I try to change the setting on the Airport Express with Air Port Utility to "participate in a WDS network" I get the error message "WDS requires multiple base stations. Please add at least one WDS peer" and I don't understand what that means.
BTW, my Airport Extreme is set up with "allow this network to be extended" checked.
Airport Express & Airport Extreme don't seem to be altogether compatible.
Any and all assistance will be gratefully received!

Can't get Target Disk Mode to work with host computer

Here's the problem. My Powerbook G4 went down a week ago (it's 7 years old) and I suspect the problem is either the hard drive or the portion of the logic board controlling the drive. I also have a Power Mac G4 400 that's running OS 10.4 Tiger. I've been trying to extract some files (that I failed to back up) from the Powerbook via Target Disk Mode using the older Power Mac as the host, however the target disk doesn't show up on the host screen. When I boot up the Powerbook holding the T key, it chimes and the FireWire symbol shows up like it's suppose to, but that's as far as goes. I plan on upgrading to a newer Mac, which would probably work better as a host, but money is a bit tight right now. Any suggestions would be appreciated.

If the trouble with the Powerbook is either a failed hard drive or a failed hard drive controller, FireWire Target Disk Mode isn't likely to work with any host computer. What you may want to try is installing data recovery software on the desktop G4 and seeing whether it can see the Powerbook's drive (connected in FWTDM) even though it won't mount. Data recovery software is often able to salvage data from drives that won't mount normally; it may be able to do the same thing via FWTDM.
These three DR utilities are all available in free downloadable demo versions that will show you what the full version would be able to recover before you have to pay for anything:

Good luck.

Can't get my audio clip to work in Keynote except in edit mode. I've followed Help instructions to the letter. Any suggestions?

Can't get my audio clip to work in Keynote except in edit mode. I've followed Help instructions to the letter. Any suggestions?

Hi Gary - thanks so much for your help. I'd already done that, but finally stumbled across the answer for my situation. I'm new to iMac and this is the first time I used Keynote, so maybe this info will help someone else along the way - I still haven't found this in any of the Keynote documentation or forums I've read.
My slides were all set up with at least one text box in which the text was animated. The sound was the last thing I added to each slide, exactly following the info in Keynote Help re: adding audio. The audio would work when I tested it in Inspector mode, and also if I switched to soundtrack instead. But not if sound was added to each individual slide. Hmmm. After I submitted the question above, I was running through the (auto) slide show one final time to check text, animation, etc. when I noticed that on just one single slide the sound effect came through, but at the very tail end of the slide. Hmm again. Why?
Through trial & error, the answer was in the animation section - not very intuitive re: audio. The steps to correct the issue were: 1) click on the sound icon embedded in each slide, 2) click on the animation tab in Inspector. 3) There's a drop-down menu there that allows you to reposition the audio clip to the #1 spot (if it was added after other "animation"). This allows the sound to begin before the text animation begins on each slide. Before doing this, I guess the sound was in there but the slides were transitioning before it had a chance to play.
Since this is the first time I've used Keynote and it's the most recent version, I'm not sure if this is a new feature to allow users to choose where within a slide to play a sound effect, but I'm guessing that might be why was unable to find any info on how to solve it. Hopefully this will help others who get stumped.
Thanks again for jumping in to help! I really appreciate it.

Can't get my epson sx535wd to work. my epson will get contact with my router (sitcom wl306) and my mac is on wifi, but they can't connect. epson can't find the computer and my report says: there are conflicting channels on my router or entry point. help

OK, let's try these................
1 - Boot up from your install DVD and run "Repair Disk" from the Utility menu. When done, restart back to your desktop, repair permissions and restart your computer. Re-connect your printer.
2 - Download & install the Gimp drivers. Make sure the one you install is compatible w/your OS-Gutenprint 5.2.8-pre1. Repair permissions, restart your computer & re-connect your printer when done.
The Epson model I have, in order to get it to print wirelessly, I had to install a Gimp driver.
3 - Check out the following KB Articles:
Mac OS X 10.4 Help: Connecting to a network printer
Epson Printer Drivers v2.10 OS X
Adding a printer to your printer list in Mac OS X
Mac OS X 10.4 Help: The printer I'm adding says "Driver not installed"
======================
If still unsuccessful after trying all of the above, the problem could be your iBook or human error. You can either call Epson & ask to speak with a Mac savy supervisor or return the printer & find another that is compatible w/your current OS.

Can I get a stepper motor to work useing an AO channel on a DAQ card?

Can I get a stepper motor to work useing an AO channel on a DAQ card? I know its a very low currentl coming out, but what Im going to be using the motor for is very weak. Has anyone tried this before? I certinaly dont want to spend 2,000+ on somthing that will be basicly moving a string on some pullys back and forth.
Thanks,
-Mark

Greetings, Mark
You can certainly use the A0 as a driving signal, but you need to amplify the current considerably to run a stepper motor. Additionally, most stepper motors require multiple phase driving signals to work properly. If I understand your application, I believe a stepper motor is a bit of overkill...you only want to use them when precise positioning and repeatability is an issue. You might look at some of the linear actuators available.

I had a bright house cable modem that also had built-in wi-fi.
Don't mean to be picky here, but if the "modem" had built in Wi-Fi, it was not a modem. It was a modem/router, also known as a gateway type of device.
A device like this combines the functions of a separate modem and separate router in one package. Turning off the wireless on a device like this does not make a it modem.....it is still a modem/router or gateway with the WiFi turned off.
I think that if I have them replace the current "complicated" modem with a "simple" one I should be able to get the guest network up and running.
That would be correct. Hopefully, they offer this type of option for their customers.

Can I operate my new laptop in dual channel mode? 15-n216us

Hi,
I have a new HP touchscreen 15.6" model 15-n216us. It came equipped with a 4GB memory stick and one open slot. I purchased an "identical" stick and installed it with no problems. ("Identical" means same manufacturer - Kingston -, same size, numbers, etc... but they are not "twins" per se.)
I ran CPU-Z before and after the install and both times it showed the laptop running in single channel mode. I swapped the sticks into opposite slots and ran it again. Each time it shows 8GB memory running single channel.
So, my question is this. Is this machine capable of running in dual channel mode? (And it not, where would I have found this myself?) If it does, does this mean that I have to buy "twins" ... ie two new paired 4GB sticks? And lastly, am I really missing much by not running dual channel mode?
Thanks!
-CD

From the Service Manual:
DDR3L-1600-MHz dual channel support
Can we have the two Kingston stock numbers for the memory modules? Generally to run dual channel they do have to be identical and a difference in latency or any other parameter can block dual channel operation.

K9N PLATINUM(NON SLI) DUAL CHANNEL MODE PROBLEM

hi
put a new system together with the following specs:
amd am2 3800+(2ghz)
k9n platinum 1.20 bios
2x512 kingston ddr2(667mhz)
pci video(yes not pci-e)have not decided which vid card to get yet.
500w psu 12v 35a,5v 25a,3.3v 25a
liteon dvd burner
seagate 300gb ide 7200/16 meg cache windows xp-pro sp2 with all updates.
not overclocking or even trying to.
no sata drives connected.
has never failed to post,boot windows and no lockups or blue screens.
ok,i am trying to get the memory to work in dual mode.
everytime i put the memory in the dual mode slots,the cpu clocks down to 1ghz instead of 2ghz.
verified by bios,windows and cpu-id
i have tried different memory(both ddr2 533 and 667)667 installed now.
also never had any install problems with windows and everything runs fine until i tried dual mode.
after the cpu clocks down to 1ghz,the only way to get it back to normal is a bios reset( load defaults
or press red button).
if i leave the memory as single channel then i have no issues.
also cpu-id says the chipset for my board is nforce 550,i thought k9n platinum had 570 nforce chipset?
this might just be a problem with cpu-id though.
any thoughts on the cpu down clock problem in dual channel mode?
thanks,jeff

1 assume you can get into BIOS with 1 stick only?
Go into the BIOS and manually set the timings and voltage to what your memory manufacturer recommends. Use a 2T command rate and see if it works.
Try both "sets" of dual channel slots, i.e. the two left slots or the two right slots.

Pc won't run in dual channel mode

Hi.I have an msi P6N SLI motherboard which supports dual channel ram configurations.I first purchased four 1gb ddr2 pc 800 ram modules and the pc wouldn't boot so i have 2 1gb and 1 2g modules which work fine.When i remove the 2gb module and the 1gb modules are in either slots 1 and 3 or slots 2 and 4(dual channel) ,the pc wont boot.When in slots 1 and 2 and 3 and 4 it works fine again.
Is there some setting i must change in the bios to enable dual channel mode.Ive looked but can't seem to find anything and the manual doesn't say anything about changing settings.
I would appreciate any help.thanks

the two 1 gb must be in slot 1 and 3 or 2 and 4 and the 2gb can be in any empty slot. then it should boot. why just do not get yourself 2 x 2gb ddr2 800. due to memory controller limitation 2x2gb is the best option for using window 32bits. and finally there is nothing in bios which can solve your prob. good luck

Dual Channel Does Not Work!!!

As the title states, I can not get anything to work in dual channel mode. I have tried 3 pairs of matched memory, and they all do pretty much the same thing. These are the modules tried:
Mushkin: http://www.newegg.com/app/ViewProductDesc.asp?description=20-146-289&depa=0
Corsair: http://www.newegg.com/app/ViewProductDesc.asp?description=20-145-432&depa=0
OCZ: http://www.newegg.com/app/ViewProductDesc.asp?description=20-146-882&depa=0
After perusing this forum I found several things to try, so I tried them all, even bought a new PSU, nothing helps. Then I actually called tech support, after about an hour on the phone(on my own dime) they decided it was a bad mobo...(which was my assumption and why I called..)
Anyways, here is what happens when I try to boot with default settings, and SPD. It will either post and freeze while trying to load windows, or it will not post, and hang during the process, at which point the monitor loses signal. The only way I can get it to load windows in dual channel mode is if I set the DRAM freq down to 266 and raise the latency values far from spec, and then it is highly unstable in windows...On top of all this, the only ram that is stable in single channel mode is the OCZ, but only when 1 module is installed...in bank 1.........can someone please help me!!

Why do I have to set the DRAM voltage to 2.9v, when everyone else has theirs set to 2.75 - 2.8v ???
you shouldnt. even corsair recommends to set their stuff to 2.7v or 2.8v and i have never heard that anyone needed more voltage on his/her memory in order to make it run stable in dual channel mode.
since you've said that you have done "all the little tricks" posted in the forum i dont know what to advice further on. maybe you tell us what you have already done...

The motherboard overview states: http://www.msi.com/product/mb/X48C-Platinum.html#/?div=Detail
Quote
• Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600 DRAM, 8GB Max
• Supports two unbuffered DIMM of 1.8 Volt DDR2 667/800 DRAM, 4GB Max
With the last BIOS, it states that 4GB modules may be possible, but looking at the memory test report http://www.msi.com/file/test_report/TR10_1393.pdf it seems this was only done for DDR2 modules, as these are the only ones reflecting this.
Suggest you check with MSI technical if the BIOS should accommodate DDR3 4GB modules as well. >>How to contact MSI.<<
Do a CMOS clear, then once in the BIOS, set your DRAM ratio so that the DRAM is at 1066. See if that works.

Z97 Gaming 5, Dual Channel RAM not working?

Here are my specs for the moment , Windows 7, Intel Core i7 4770k, 8,00GB Single-Channel DDR3 @ 666MHz (9-9-9-24), Nvidia GeForce GTX 780 (EVGA)
As the title says dual RAM is not working, when I put all 4 RAM sticks in their slots or even just two in dual channel mode my monitor will not respond and the screen is just black, can't even go to BIOs.
The BIOs settings are at 1333 MHz and 1.5 v, I've tried raising the volt and lowering it, anyone have any ideas?
I've tried the 1-3 and 2-4 slots with two 4gb sticks and it does not work, but the 1-2 and 2-4 works fine, have also tried all the individual sticks so none of them are faulty.

Please clarify. You mean a single stick works in 2 or 4 but not 2 and 4 together? So that means DIMM slot #3 is the only one that doesn't work at all? My suspicion is a grounding or short under the mainboard by an errant standoff, or the DIMM slot has some debris in it, or the slot is just plain faulty. Other possible is a pin problem in the CPU socket.

After I exported a PDF to a Word doc and downloaded it, I can't get the pointer tool to work. When I click on the document text, the only tool is the "move" tool. I can't edit or select text. Please advise.

Version of Adobe: Adobe ExportPDF (not Pro)
Operating system: Windows 8.1
Steps I am taking: When the PDF file is selected and opened, I clicked on Tools menu on right side of the screen; then I clicked on Select PDF file; then under Convert To, I selected Microsoft Word (*.docx); then I hit the box below that; and clicked Convert. I then see the message that says it is Converting to Export PDF Online. Then I see a link below that, that says Download Converted File. This takes me online to Adobe Acrobat .com, where, I see the command, Export PDF, and see a blue box on the same screen that says Select PDF Files to Export. I click on the thumbnail of the file I want to export. This brings up, online, a screen containing the file I wanted to convert to Word. Then, on the same screen, I click on the icon on the right hand of the screen that says Download. then I click on the box on the bottom the screen that contains the Word document I had wanted to convert. This brings up the Word doc. in Compatibility Mode the latest Word version, which I am unfamiliar with and which has a Picture Tools tab that I cannot escape from and I cannot get any selection tool other that the Move pointer, and I cannot find the Select text pointer to select any text on the page. I don't want this Word version and do not know how to return to the old version of Word that I am familiar with.
Can you help me, please?
