Dell :: Does Dual Channel Memory Have To Match

Apr 19, 2009

I have a Inspiron 1420 with 2GB of RAM. It's probably two sticks (my wife's using it now so I can't check) of 1GB.

Question:

If I want 3GB of RAM, and replace one of the 1GB modules with a 2GB one, will I lose any dual channel benefits?

HP EliteBook 8540w :: Identifying Correct Memory Slot For RAM Upgrade To Enable Dual Channel Memory

Jan 12, 2015

I just purchased a used Elitebook 8540w with i7 quad core and four memory slots (I love it!).  It is running 64 bit Windows 7 Professional  It came with one 4gb memory module and I purchased an additional 4gb module to bring total RAM to 8gb.  
 
I have the HP document that shows for two 4gb memory modules, one should be in memory slot 1 and the other in memory slot 3 for correct functioning of dual channel memory.  All set right?
 
Not quite.  In the Elitebook 8540w, the primary memory slots under the keyboard are clearly labeled "1" and "2"  However, the expansion memory slots on the underside of the chassis are also clearly labeled "1" and "2"  Opps!  There is no "3" and there is no "4"  In which of the unfilled three slots do I install the second 4gb module for correct functioning of dual channel memory?

Dell :: Inspiron 6400 E1505 And 4GBs Of Memory (Questions About Dual Channel Mode)

Apr 13, 2009

I have a question about 4gb of memory on inspirons. I recently put in 4GB's memory in my inspiron (Corsair brand) and I am running XP(x86) aka 32bit. Windows sees 3.25gb's which is exactly correct.

Awhile back I read that the inspiron motherboard which is an intel, will not run the memory in Dual Channel mode, which will slow the memory down about 3-5%. However I am not sure of how true or not this is. I put the memory and checked my bios and its showing all 4GB's and "Dual Channel" enabled.

So the question is how real is this dual channel concern if the bios is saying its in dual channel mode? PS we are both running the latest bios A17.

Dell :: 6GB Dual Channel Ram (XPS 16)

Apr 14, 2010

The XPS 1645 offers choices of 4, 6, and 8GB of ram. Just out of curiosity, how can 6GB of ram be dual channel? I was under the impression that dual channel requires matching pairs, and that 6GB of ram would be one 4GB stick and one 2GB stick. However, the Alienware laptop seems to have listed what I would expect (3 and 6GB configurations not listed as dual channel).

See below.

[XPS 1645]
4GB Shared Dual Channel DDR3 [Included in Price]
6GB Shared Dual Channel DDR3 [Add $225.00]
8GB Shared Dual Channel DDR3 [Add $375.00]

[Alienware M15x]
3GB DDR3 at 1066MHz [Included in Price]
4GB Dual Channel DDR3 at 1066MHz [Add $50.00]
6GB DDR3 at 1066MHz [Add $200.00]
8GB Dual Channel DDR3 at 1066MHz [Add $350.00]

Dell :: E1505 Dual-channel Fail

Dec 19, 2009

She has been wanting to make the windows 7 switch, however she only has 512MB ram in it, so she ordered a 2x1GB ddr2 667 Crucial kit off Newegg for me to install.

After it arrived I popped open her memory compartment and lo and behold there were two 512 sticks already in there. I was puzzled by this, so I installed the new ram and went into the BIOS, which reported that dual channel mode was running and there was only 1024MB of memory.

I naturally thought one of the memory slots was dead so I tried each stick in one slot at a time, each time it booted up with the exact same info, 1024MB of ram. From this I can only conclude that it simply refuses to actually run dual channel, despite both slots being perfectly functional.

I have flashed the BIOS, to no avail, and now have no idea what to do.

HP/Compaq :: DV6-1264CA RAM Not Dual-channel

Aug 24, 2009

its an HP DV6-1264CA Artist edition v.2 16" LED backlit 1366 X 768 (comp in sig)

-AMD Turion Ultra ZM-82 2.2GHz
-AMD RS780 Chipset
-2 x 2 Gig of Samsung DDR2-800 RAM
-ATI Mobility HD4650 1 Gig GDDR3
-1x Western Digital Scorpio Blue 500GB

All that on Vista Home Premium 64 bits. It's nice by the way, and I can play COD4, Doom3, HL2, Quake4 (my faves) at high details...of course I don't max out Crysis...lol but for last year's games, it's fine, especially for a lappy that cost $999 Canadian

I'm running all kinds of diagnosis tools to check on everything on the lappy:

-Everest Ultimate, CPUZ & others...

There is NO mention about the RAM running in dual-channel.
In CPUZ, where I should see DUAL, the area is grayed out.
I know there is 2 sticks of Samsung DDR2-800 (2 slots and the platform is able to run dual-channel according to AMD).....

Acer :: 5920G Dual Channel With 800mhz RAM

Oct 7, 2009

My current RAM is:
1gb Corsair DDR2 667mhz (default from manufacturer) and
2gb Mushkin DDR2 800mhz

I searched through the internet that Acer 5920G can only support up to 667mhz.

The problem is, I'm planning to add 1gb more RAM, so it will be 2 x 2gb Mushkin 800mhz, since both of them will be downclocked to 667, will both of them still run in dual channel mode ?

I wanted to buy 667mhz one, buy every shop near my place says that 667mhz ram not distributed anymore and the price is quite the same.

Dell :: Installing Addit. 2GB RAMe1705/9400 32bit OSis There Any Sense? (dual Channel?)

Mar 21, 2009

I posses a dell 9400/e1705. Currently I have 2GB of RAM installed (in one piece). I was thinking of installing an additional 2GB. I was wondering if there is any sense in doing so.

First of all I have 32bit system, so the whole amount (4GB) will not be recognized. Secondly I am unsure if I will notice any increasement in performance. I mainly use the computer for photo retouch in Photoshop (I operate on big RAW files) and sometimes I install games.

A friend of mine said this would a good idea beacause even though the system will not see 4GB the chipset will allow the two memories to work in dual channel (If i were to add just 1GB I would have a total of 3GB but no dual channel).

Dell XPS 15 :: Service Tag In DSOE Does Not Match The Current System

Mar 23, 2011

Around 60% of the time when I turn on my new Dell XPS 15 laptop, I receive this error message, attached. The actual error message reads 'Service Tag in DSOE Does Not Match the Current System'
 
The only thing I can attribute it to, is an Acronis TI Home 2011 restore, as I wanted to check to see whether the image would actually work. NOTE: I did make Dell Restore DVD's first.

Dell Inspiron 15R SE 7520 :: Keyboard Mapping - Match Entries With Keypad Layout

Mar 13, 2013

How to make my keyboard entries match the keypad layout? I have tried several English keyboard layouts available from the installed files but none of them exactly match my layout. For instance one layout (English International) require a space after every " or ' before the character will appear. I can understand this as it allows for certain special characters related to other languages. If I change to plain English then the key comes out as #. I have downloaded Microsoft's keyboard mapping application but it does not seem to work in Win8. I don't get any layout diagrams when I load a keyboard file. I am pretty sure it is the layout file because an external keyboard gives the exact same characters as the Dell factory installed kbd. I know there is commercial mapping software available but I don't want to buy it and find it won't work just as Microsoft's doesn't.

Under the hood of the 17.1-inch Firefly we found a 2.4GHz Intel Core 2 Extreme Quad Core CPU, 4GB of RAM, a pair of ATI Mobility Radeon HD 3870 GPUs running in CrossFire mode, and a 7,200 rpm 250GB hard drive. The Firefly spec sheet said the machine is capable of overclocking, but we didn’t touch the BIOS.

And a MultiTouch trackpad, Backlit keyboard (with m15x-esque customizable colours), Creative X-Fi audio and a Dual Hinge like the HDX 20.

Lenovo ThinkPad W Series :: W540 - Dual Monitor Display Resolution With DVI-D Dual Link Cable

May 18, 2014

I have recently purchased a W540 and connected to my Dell u3011 30" monitor. I used the Dual Link DVI-D cable that came with the monitor and plugged it into my Ultra Dock. The maximum resolution i can get is 1920x1080? When i change over to a Display port cable i can achieve the full 2560 x 1600 resolution? Is there something i need to do in addition to achieve the full 2560x1600 resolution with the DVI-D dual link cable? I want to be able to connect 2 laptops to the one monitor and only have 1 display port input so i need to be able to use the DVI cable on the 2nd machine while still achieving 2560x1600 resolution.

HP/Compaq :: Presario V3000Dual Channel

Jul 31, 2009

I have looked up both the motherboard (Wistron 30b5) and my laptop model but cannot find whether it supports dual channel ram. I have the Sempron CPU. I currently have 2x1gb on order but if it doesn't support dual channel then I will return it for a 1x2gb and keep a 512mb stick in the second slot.

While we are at it, does anyone know which processors could be used with this mobo?

Dell :: Memory Speed Affecting Windows Experience (memory Operations)

Oct 13, 2008

A friend just showed me his new Dell Vostro lappy. He has 4 GB of DDR2 800mhz memory on it when compared to my 4 GB of DDR2 667mhz memory on my XPS 1530

However, under his windows experience score - he gets 5.9 score for memory operations while I just get a 5.1. I can't believe that a couple of hundred mhz can result in such a drastic difference.

Is there something optimized for his system but not for mine?

Lenovo ThinkPad W Series :: W540 - Display Brightness Keys Not Working / Audio Channel Commutation Gets Stuck

May 27, 2014

I've got 2 separate but really annoying issues with my W540 20BH:
 
- display brightness keys not working: when waking up from Hibernation mode, sometimer (really, randomly!) the display brightness keys (Fn+F5/F6) don't work.... either if the display brightness is stuck on max, min or an intermediate level...Is there a way to shut down and restart the process which commands the Fn keys?
 
- audio channel commutation gets stuck. Normal behaviour of the audio configuration is:
1) speaker volume disabled, mic disabled
2) when plugging in a 4-pin headset, headset's volume is on, headset's mic is switched on; speaker volume is still disables.
3) when unplugging the headset, speakers' volume is still 0
 
After each boot, the audio channel is at 0, but doesn't commute to the headset when plugged in! I have to open Configuration Panel, realtek properties. With this window open, unplug and re-plug the headset. Now, the volume has its normal behaviour.
 
Any better way to configure audio channels and evenments, which is able to bypass realtek's manager?

Dell :: Anyone Have Dual HDDs In Their XPS 16?

Oct 30, 2009

Looking at the new XPS 1645 since I need a laptop before the new year and since it's pretty much identical to the current XPS 1640 in terms of the body AFAIK,

I was wondering if anyone has replaced the DVD drive with a HDD caddy and have pictures of how it fits? Specifically, I was looking at products from nando4's thread:

DIY: Adding SSD or HDD storage using an optical bay caddy

I believe people said it was possible but I lost the post somewhere in that massive XPS 1645 owner's lounge. The questions I had were:

1) The DVD on XPS 16 should be a 12.7mm SATA and I was wondering what specific HDD caddy was used? From the thread above, this might work .....

Dell :: Dual Boot : XP And 7

Feb 5, 2009

I formatted my XPS M1530 using this guide (How to: Step-by-step guide for installing Windows XP on XPS M1530) and everything worked perfect.

But when I rebooted, I realised that the computer booted directly to XP and didn't let me choose between XP and 7. Normal, I thought, so I stuck in the W7 CD and selected the "repair" option. This did the trick very neatly, repairing the W7 install. The only problem was that now it will boot ONLY to W7 and I still have no selection screen for the OS.

I reformatted the laptop right after purchasing and no longer have the recovery drive. Here is what Vista says I have:

Dell :: Dual Intel X-25 SSD In M6400

Oct 20, 2008

I opted for 2 7200 RPM drives for my configuration. I also selected the quad core processor, 1gb video and 8gb of ram. I was very close to purchasing with SSD drives, but my first experience with SSD wasn't very good. I purchased one of the first XPS 1330 with the 32gb SSD option. I really bought into all the hype and after about 60 days I swapped it out with a 7200 rpm drive. Anyway, looks like SSD drives have improved drastically.

I was just reading some reviews and performance tests on the Intel X-25 80gb SSD drives. I'm considering buying two for the M6400 and setting them up RAID 0. I really don't care about storage space.
