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).
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.
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).....
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.
I want to enable my RAM in dual channel mode... what is the process to do this? i have already checked in CPU-Z that it is currently in single channel mode.
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.
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).
I upgraded RAM on my W530 and it's working only in single channel mode. How to enable dual channel in BIOS? Â Here is screenshot about my RAM : [URL] .....
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?
I have the docking station which has an output for digital coax audio. Dell is telling me that the m65 is limited to 2 channel output. Is this true or is there a driver that I can download to fix that?
It sure does look like that Clevo 18in revealed sometime ago.

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.

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.
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?
I've got 2 separate but really annoying issues with my W540 20BH: Â - 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? Â - 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 Â 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. Â Any better way to configure audio channels and evenments, which is able to bypass realtek's manager?
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 .....
I have seen several sigs with people that have an e1705 with dual HDD's...But I can't seem to find any info on it. I need more HDD space, but I do not want to have to re-install everything on a new one. It would save a lot of hassle.
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.
Looking into getting a Dell XPS series, but can't find any info on having dual HDD bay's.
I really like this feature on my HP, but dollar for dollar Dell has much better hardware out of the box. Some one let me know if any Dell's have this. Probably going to wait till Windows 7 comes out.
I am trying to dual-boot Windows 7 on my XPS M1530 which is currently running Vista Ultimate - BUT I stumbled upon a problem. As I understand it, Vista will only allow you to have 4 partitions and magically I have 4 already.
I reformatted the laptop right after purchasing and no longer have the recovery drive. Here is what Vista says I have:
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.
I'm running Vista 32 bit on my notebook and desktop and I have an xps 1640 on its way with Vista 64. I've always been very happy with Vista but I would like to try Windows 7..
I haven't set up a dual boot system since Windows 3.11, so I was wondering if the process is pretty straight-forward? When I start up the Windows 7 install dvd, will there be an option to setup dual boot?..
I'd like to try this on my xps 1530 first, but I want to make sure that I don't do something that would crater the Vista OS currently on it. Would I be better off waiting for my 1640 to arrive to play with Windows 7?.
I partitioned my HD and installed Vista on e: drive. Vista worked fine, and I have the option to boot either XP32 or Vista 64. However, both OS can see C: and E:. Therefore when I do an install I have to make sure I don't install anything on C: when running Vista.
having trouble with my second monitor that I am trying to connect.
I am using a DVI to HDMI cable and inputting it into the second screen (It is an lcd tv).
Windows 7 allows me to change the resolution of both monitors seperately. i made my regular monitor the same 1920 x 1200, but no matter what resolution i make the second screen, the edges, top bottom left and right are all cut off, sort of like a cropped version of what i should be seeing .....
