32 bit windows 7 and Two- 4GB sticks of RAM and dual channels

Hello,
I have a Desktop running Win 7 32 bit. At the moment I have 1 4GB stick of RAM in. I have another 4 GB stick of ram(Same brand as the first one) . I know win 7 32 can't go over 4GB of RAM but was wondering if I put both sticks in will I get better performance
because it will be using dual channels or will it just MAX using the first stick and never see the 2nd becasue it is already using the full 4GB off the fist stick.

Thanks for your reply. I understand in reality I have really about 3.25 gigs. But if I had both sticks in would it be using all that 3.25 on one stick or would it split the 3.25 between the two sticks.
If you have 2 sticks of 2gig in run on dual channels I am told performance is better then just having 1 stick of 4 gig. I am just wondering if if I used the 2 4gig sticks which will only give me 3.25 gig will it use the dual Channel which would help performance.

  • HT1270 Hi, I have bought macbook pro a year back and it has 4 GB RAM and its mid 2012 model can u tell me whether if i give the macbook for upgradation of memory will they do it and what would be the cost

    You need to take your MacBook Pro to your Apple store genius bar and check that they will do the upgrade for you...price for 4 GB memory used to be $200 but you will have to check with them for the current cost.
    You can also check with OWC, http://www.macsales.com and see what their cost is and decide if you want to do it yourself.  Cost will be about half of that at the Apple store.

  • HT1420 I use two MacBook pro, two iPads and two iPhones. Upon connection and attempt to synchronize photos I receive a message that my authorization limit is exceeded. I read that iOS devices do not count against the authorization limit.

    I use two MacBook pro, two iPads and two iPhones. Upon connection and attempt to synchronize photos I receive a message that my authorization limit is exceeded. I read that iOS devices do not count against the authorization limit. One iPhone and one iPad show in the authorization list. iTunes wants to delete my purchased programs and books from the iPad to continue synchronization. What can I do?

    Ok, now I do wish I could edit....
    I forgot to APPLY the network settings for the USB cable to work. Connected thru USB I can tether.
    So, I kept playing, and playing some more...
    I had previously unpaired everything, and gone as far as removing network devices HOWEVER...
    I didn't remove the Ethernet, Firewire or Airport Network devices.
    Now, I have done so. I REMOVED EVERYTHING
    No pairing, no network devices.
    Bluetooth was already turned off, and I rebooted.
    I turned off tethering and rebooted the iphone.
    I turned on bluetooth (on the MBP), I turned on tethering. I browsed for the iphone. It said I was already paired???? Ok, repair AGAIN, and THE IPHONE SHOWED MY BLUETOOTH TETHERING BLUE BAR at the top of the screen!
    I opened a web page, no go... d4mn, I was close...
    Opened network preferences and the created a new bluetooth PAN and voila! Internet back on the MBP. I am about to reinstall the ethernet and airport (I can live without firewire for now) and see what happens.
    Basically, the link I posted two posts ago, I had already done that, but I NEEDED to remove ethernet, firewire and airport as well...
    So MAYBE it's fixed, we'll see for how long. I'm not going to mark this as answered for now, because basically, it has failed for no reason, and I want to know why...
    Hopefully someone can come up with something, but having to delete and reinstall all pairings and network devices (to me) is not really a solution, it's a workaround (at best).

  • IMac and Video:  4GB vs 8GB RAM

    Hi all, long-time Mac user, first-time poster here. It's time to upgrade the old 2003 G4 MDD with a new platform. A Mac Pro is really expensive right now, so am looking at a 2.93GHz Intel Core 2 Duo, with 4GB of RAM and the ATI Radeon HD 4850 card. I intend to occasionally make videos -- let's say YouTube quality with the occasional family-release DVD. Is 4GB of RAM and say, Final Cut Express/iMovie, good enough, based on your experiences? I've more interest in Illustrator and PS and assume those are fine with 4GB.
    It's $1k to double the RAM to 8GB -- that's a big chunk of Adobe CS's price. And do you think that Snow Leopard will treat 8GB better than 4GB for video?
    I'm asking because I recognize that the iMac is not as upgradeable as the Mac Pro is. Thanks in advance for any thoughts -- a grand (or more) is riding on this!

    You should be fine with 4GB; even 2GB may be sufficient for what you describe although that is irrelevant, since you cannot get that config with only 2GB of RAM.
    If you really find a need for 8GB of RAM, you can upgrade it later using third-party RAM. The prices should come down. Even today, you can get a matched pair of 4GB modules from OWC for about $700
    http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/
    and you get to keep the stock 2x2GB modules as backup. When you sell your iMac, you can put the original RAM back and have the 2x4GB modules to sell separately. That makes much more sense than spending $1000 up front, and not having the extra set of RAM.

  • Z77a-g43 unable to run ram in dual channel mode

    In fact, I'm unable to run any configuration aside from where i have both modules in the 2 slots closest to the cpu. I tried every permutation with 2 sticks, both with my new g.skill ares 8gb sticks, and my old g.skill 4gb sticks.
    I would try manually increasing the voltage a little, but there are only 4 settings "1.35v, 1.5v, 1.65v, and 1.8v".

    Give 1.65v's a try, but from what you describe, it could be a problem in the CPU socket. Bent pin(s) or poor CPU pad to pin contact.
    Added: To be more thorough, it could also be a short between the mainboard and the case (errant standoff(s), faulty dimm slots (for two to be faulty, extremely rare), CPU faulty (again rather rare).
    2nd add: Actually, I missed another possible. Recommend to test each RAM stick individually in the primary dimm slot.

    When you begin a new project, you'll see a button for the project settings on the new project option screen.
    When you click this, you'll be taken to a list of project presets. Your successful use of the program depends very much on your choosing the right one for your camcorder.
    As I say,  there is one that is specifically designed for working with JVC GZ cams. I believe you'll find it in the Hard Drive/Flash Drive set.

  • I installed two 512 dimms of RAM and now my monitor doesn't work!

    My G5 tower came stock with 2 dims of 256K. I just installed an additional two 512 Dimms and turned on the computer, only to find that there is now NO picture! I took out the dimms and turned it on with just the originals installed and same thing. I blew out the entire cabinet with compressed air and turned it on again and same thing...nothing! It seems that my computer is fried. Is this possible? Is this a common problem when installing RAM? I'm sure the dimms are in all the way. They fully click in and fit just fine. Anybody have any suggestions, before I take my computer to a MAC store and probably pay way to much to have it fixed? Thanks.

    Hi! Did you buy ram that was guaranteed to be for the Mac model? Second, sometimes after messing with hardware a pmu/smu reset is necessary. The early G5's have a tiny button on the motherboard that you should push once with everything unhooked. On the later ones unhook everything (all external cables) and let it sit for 30 minutes. Tom

  • For four years Ive been unable to use my home network as anticipated. I have ADSL connection with O2, airport extreme, three expresses, two minis 10.6.8 and 10.7.3, and two pros 10.6.8 and 10.7.3, and a cinema thbolt display. Id like to use bbc iplayer.

    I am unable to stream video and I lose connection frequently. Ive tried it using wireless connection and with ethernet. Ive tried using the O2 router (%series) as a modem for the extreme, Ive tried using the O2 without the extreme - not poss to extend network but MUCH faster, and Ive tried using a variety of other routrers and modems. My flat is 10m x 6m, there are no other wireless devices within or immediately adjoining except for my wireless landline phone that I have changed three times. Every single piece of my home network has been to the genius bar at least three times and the entire network with all devices has been taken twice. Genius bar have found either no fault or no explanation. Applecare dont seem able to tie their own shoe laces and have been worse than useless, suggesting things like checking a plug fuse (good advice but not relevant). I met a chap socially who turned out to be an apple employee home networking specialist. He offered to look at it and came to my flat. I quote him now: "F**k me, its just not supposed to do tha., Theres something seriously wrong with the system. It's an Apple problem completely". However, despite repeated requests I have not been invited to escalate the issue beyond the genius bar. Enen though everything possible is apple (they dont make a modem for ADSL??), all I get from them is it must be the fault of something else.
    PS Ive had my O2 connection checked tens of times and paid for a bt engineer to check my line 4 times.
    PPS The thunderbolt display was sold to me after I refused one on the grounds that the location of my mini was more than 2 metres from the display, and the salesperson reassured me that the thunderbolt connection was universally available and that  would have no problem connecting the display to my mini 5 metres away.
    I may well not be  too bright when it comes to computers, but with their attitude of there being NO SUCH THING AS A BAD/FAULTY APPLE PRODUCT, ONLY SILLY CUSTOMERS WHO HAVENT WORKED OUT HOW TO USE THEM YET, I wish I will soon see their brand will rot in commercial oblivion ****. I have focused this on home netwrking but that is the tip of the iceberg. However, having invested so much of my life and my money in what I have, please can any of you good people out there show me the foolish error of my simple ways?

  • Is the 13 inch powerful enough to run CAD and simulation software with 8gb ram and i5

    Or would you need upgraded specs?

    I got the 15" rMBP instead.
    Call the local Apple Store and ask if you can test your software on their computers. I was allowed to do that. I did and that is how I decided.

    I also went to compaq and tryed a driver i found there without any luck. Im thinking at this point it is an OEM
    Although i still dont understand how you got compaq from the model number, im going to continue looking around their site.
    Maybe ill luck out but so far im about to the point im ready to throw this @#$%@%#@$@##@$#@$% thing away lol.
    Im looking on driver guide now again. :Sighs This is so aggrivating Normally i wouldnt have bought a card without the drivers but
    my wifes the one that got it and she didnt know. Oh well......
    You can get the model information from here.
    You can also try by installing kX drivers -> if kX package don't get installed, your card may have some problems.

  • Brightness OSD not working in 64 bit Windows 7

    Hi,
    After having used the laptop for a long time with a 32 bit Windows 7, I've upgraded the RAM and added an SSD, and reinstalled with a 64 bit Windows 7. Everything works great, some things even better than before (used to have occasional problems hibernating, but not anymore). However, there is one small, irritating problem:
    The brightness OSD is not working, even though the buttons do control the brightness and every other OSD is working properly, only this one isn't.
    After installing windows, I've used the ThinkVantage System Update utility to install everything. Then I tried installing all kinds of drivers seperately. So far, no luck.
    I'd really appreciate some help resolving this issue.
    Thanks a lot

    I've tried several different versions of the On Screen Display from the Hotkey Features Integration for Windows 7, including 6.60.03, 6.60.01, 6.60.03, 6.42.00, 6.24.00. And every time, it's the same thing. Everyhting works but the brightness control OSD.
    What else can I try?

  • K9NGM not working with two sticks of RAM

    Hi
    I've not posted on here before.
    I have recently built my own system - for details see below.
    It has been working fine with dual boot into XP and Vista (Vista only installed after updating the BIOS to BOSSKILLER's version 3.23)
    I have bought an extra stick of RAM and made sure it is exactly the same as my current stick.
    I cannot get my system to work with both RAM sticks installed.
    When booting into XP with the 2nd stick installed, the PC randomly freezes. Sometimes with a beep coming from the internal speaker.
    The mouse and screen and keyboard just stop. This can happen at any time - but always within a few minutes of starting up.
    If I try with Vista then it won't even boot. I can go into safe mode, but the last thing it does is load crcdisk.sys. Nothing at all happens after that.
    I can use both OS's fine with just one stick of RAM installed. I have tried with both sticks independantly and both seem to be OK. I have also used memtest.org and all the tests complete with no errors.
    I have checked the motherboard manual and can confirm that the two sticks are correctly installed in dual channel mode.
    I have read elsewhere that adjusting the voltage settings of the memory in the BIOS could help, but there is no option for doing this in this BIOS version.
    Any help or advice would be greatly appreciated
    Thanks

    Just an update to say that I have it all working now.
    I did loads of memory tests etc.
    Both memory sticks showed up no problems with the tests.
    I eventually managed to find an update to the BIOS to version 3.3 and it's all working wonderfully now.
    Boots into Vista and XP with both sticks installed - running Dual Channel no probs.
