Sony :: Memory Remap To See 4GB RAM On VGN-AR31S, VGN-AR21S, VGN-AR41S
Jan 5, 2010
I own a VGN-AR21S, but the following is also true for the 31 and 41 series and lots of other models.
Although the specs say that the max supported ram is 2GB I upgraded to 4 GB without problems, as the chipset supports them.
Well, almost. The problem is that the BIOS does not do the so called memory remap, and thus the upper 1 GB cannot be seen and the system reports 3GB available (on Windows 7 x64, but also Vista, Linux, etc).
I already upgraded the BIOS to the R0200J6 version supported by AR31S in order to enable VT (through the notorious symcmos hack), thus I was wondering:
Does anybody know if it's possible to upgrade to later BIOS versions? (e.g. the R2090J8 supported by the 71 serie which fully supports memory remap)?

Installed some days ago and all runs fine (too much better than original Vista 32), except:
- Multimedia, S1, S2, Fn and volume buttons (dont' care for me)
- Memory Stick and Memory SD readers (important for me)
- AVermedia TV tuner (important for me)
where can I get these drivers?

Specifically the F-keys.
currently the dominant functions of f1-5, and 7-12 are:
screenswitch, wireless, battery, brightness down, brighness up, mute, volume up, volume down, rewind, play/pause, and fast forward.
This means any time I want to use one of these F-keys i have to press function...it also means that when I'm playing wow if my hand slips while hitting the 2 key I end up disconnecting my self from the game (internet off!) UNACCEPTABLE!

I had a registry hack to remap the quickplay button that worked fine under XP. This is the touch sensitive control at the top of my dv5t next to the mute, volume, play controls. Under XP the location was:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerAppKey18
But it doesn't appear to work under Win 7. Does anyone know the location for Win 7?
I don't want to install Quickplay, and didn't need to under XP. All the other buttons work fine out of the box.
I've seen two locations for Vista:
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCyberLinkQuickPlay
Change the key "Main" to the path of the program you want (sans the quotation marks if you copy it as a path). The original value of this is something like C:Program Files (x86)HPQuickplayOP.exe (no quotation marks). Replace that. I replaced it with C:Program Files (x86)Microsoft Origami Experience Pack 2.0Origami Experienceox.exe (Origami central executable).
and
You can reassign the quickplay button to open any program by changing the "QAction" value in [HKEY_LOCAL_MACHINESOFTWAREWow6432NodeHewlett-PackardHP Quick Launch Buttons].

solution to remapping the annoying Envy special function keys
[url]
I bought an envy about a month ago and have been working through the usual new laptop quirks. There are plenty of hard-to-notice-until-bought pros and cons that I might pour over some time, but right now I'd just like to mention my findings with respect to the Envy Quick Launch keys that are located on the left of the keyboard.
By default, these keys open up a mail program, HP's MediaSmart SmartMenu, a web browser, printing, and the Windows calculator program. You can see them on the left side of the keyboard, with labels I'll explain in a moment:
There's no way in the HP software to customize the buttons, so I did a little bit of fishing around and found some useful information.
My original intent was to make a small program that would sit in the system tray and simply have a menu to disable all the buttons at will or re-enable them. The buttons are nice, but they aren't the most useful thing to have enabled when one is trying to play a full-screen game. I'd keep getting sent back to the desktop because I accidentally opened a calculator instead of pressing ctrl............

today I received new memory and right away decided to do easy task, install it to my VGN-TX51B/B.
It looked easy just until I opened the memory cover and found out there is some kid of mechanism, which I don't know. Nevermind, just slide it there and lightly pressed and it was there, even though not in the way I expected (see red circles)
Turned on, checked in My Computer...and surprise, there's written just 504 MB of RAM. Quick check in SIW and it looks like it's installed properly

My configuration is with 4GB single slot right now. Considering that an extra 4GB single 1066 DDR3 aftermarket DIMM would cost me about $170, what would I gain by upgrading it to 8GB in total?

I got a Vaio Z620D, it's a Canadian Model. It's got only 2GB of ram, so I am looking to add 2 more. I was told that it should match the frequency or something like that, I am not too sure about the whole deal.

Here is the detailed specs for this laptop, just scroll down for the RAM info.

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?

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 a problem with my FZ21M and need to narrow down the faulty component.
Purchased from amazon uk in feb 08 and have had no problems at all with it.
Haven't used it in a few months and has been safely stored.
Last week I booted it up and all was fine but in the course of installing many microsoft updates it hung and after powering down would not boot into windows.
I used the recovery software and got it back up and running. Checking the hard disk took forever with many errors. Still, seemed ok but then froze again on windows update .....

I have a Sony VGN-NR310E with Windows XP Pro on it. The maximum memory is supposed to be 2gb. But my son showed me tonight with a 2gb chip he had just ordered for his laptop, that my Vaio would recognize 3gb of memory. Windows showed 2.99 My question is, has anyone tried this? If so, will it recognize 4gb? I want to order some memory from new egg but I will wait until I hear from others that have exceeded listed memory limits on this model.

For few months already I am getting irregular bluescreens announcing "Memory Parity Fail" on my FZ11E.. Most of the time it's when the computer has noticeably warmed up but not always. Sometimes there's no crash for weeks and suddenly it's here again and keep coming back several times per day.
My guess would be the memory gets overheated, probably because I upgraded from 2x512MB to a cheap pair of Corsair's 1GB. However I suspect my computer might have a tendency to get too hot by itself even if I keep it on hard surface and always on a Balanced power plan. Memory tests show no errors so I can't know for sure.
The question is, how do I find out if the problem is in RAM or the cooling system? I'm willing to buy a new pair of memory modules but want to make sure it will fix the issue.
CPU: T7100 @ 1.8GHZ x2
RAM: CORSAIR DDR2 1GBB SODIMM 667MHZ CL5
VIDEO: NVIDIA GEFORCE 8400M GT 64MB

I just bought 2x2GB (DDR2 667MHz) of memory for my VGN-C1Z laptop (unfortunately I did not check before if 2X2GB was supported). Now, as far as I understood the Intel 945PM should support this, but the laptop in itself was said to be 2GB limited.
Using Windows XPPsp3 with those 2X2GB success to boot but at the end I got black screen (I see the Windows logo and progression bar, it stops displaying some sec before the startup sound), then I success to remotely connect to the laptop through VNC, here I can see that Windows is reporting 3GB which looks "normal", and under driver tab I can see in system area a warning under the line "Mobile Interl(R) 945GM/PM/GMS/940GML and Intel 945GT Express PCI Express Root Port - 27A1" saying "This device cannot find enough free ressource to work properly (Code 12). If you want to use it you need to unactivate one of the other system device" [message was in French, this is my translation], the version of the pilote is 7.1.0.1015. I'm using BIOS version R0035J4, in the BIOS only 3GB are reported. Running Everest I saw that PAE is supported and activated, and the memory is detected, you can see here the Everest report: [url]
If I boot with 1x2GB it's ok (so the mem slot works ok against 2GB). If I boot with 1x2GB + 1x512Mo, it's ok too, so It's above the 2GB limit announced.
I tried to change the video driver, and also switch to VGA with same black screen of course.
So... what can I do next to try to have 2x2GB working (even if only 3GB are available) ? Does it looks a driver/Windows issue ?

I have a VGNSZ645P3 Vaio which I got as xmas gift. I decided to Max out the RAM and purchased Crucial 4GB kit. Sony recommends Crucial as only authorized after market RAM. I have previously upgraded memory on desktops and laptops and am fully aware about the ESD. I changed the memory 45 degree angle, snap it down....I try turning the computer back on and it will not turn on. Power light is on, the battery light is on but the other 3 lights will not light up and screen does not turn on. I put the original back on and it still will not turn on. I took it to sony store and the guy tries same thing I do and it does not work. He says the motherboard is probably toasted...I said how could it be I followed every direction possible and he said sometimes that the Memory has ESD on it. So they put the original factory RAM back in and shipped it out to San Diego. I thought that warranty was void if you mess with original RAM? Im hoping they'll fix whatever that is wrong with it and not come back with "you messed with RAM warranty is void".....
Has this memory issue happened to anyone?

family member install some additional memory in her Sony VAIO laptop, but seem to be having a problem. Its a VGN-C290 model (May 2007) and currently has one 1GB chip installed & has one open slot. It allows a max of 2GB.
Now, I have purchased an additional 1GB chip from Crucial.com, but after installing it in the one open slot, it appears that it is not recognizing it at all. The laptop will turn on, but doesn't get to the XP screen. Not even the Sony VAIO/Phoenix welcome screen either.
I have never had a problem with Crucial memory, but I contacted them directly to maybe help with this problem. They basically told me to make sure it is really seated in there good and apply a lot of pressure. They also had me put the Crucial memory in the slot #1 where the original Sony memory was. Neither worked.
The only other thing they suggested was that it was a BIOS related issue & to somehow update the BIOS. I checked & it currently is running BIOS version #R0080J4. I'm trying to determine if this is the latest version. If not, then how to update it.

While eagerly scouting the Zs, I've greatly enjoyed this forum for the past few weeks. I've been stopping by (ok stalking) my local Sony Style store to check them out in person, and became curious about a discrepancy.
Does anyone know off hand if there is an inherent memory speed or bandwidth difference between the 520m and 540m (or 620m)? I haven't noticed anything official from Intel or the Sony specs, other than they all use DDR3/1066 sticks.
Last week I snapped a picture (rather fuzzy cellphone, sorry) of the WEI screen for the lone silver GX/S (i5-520m) floor model. It shows a lagging score of 5.9 on memory, which doesn't jive with other performance scores mentioned on this forum (that I could find).....
