Windows 7 running slow after memory upgrade

Memory is recognized by bios and windows 7 after using a jumper to the 2 outer pins on the fan connection. But, if I install more than 2 gig, windows runs slow and choppy. memory type and install position are correct. I've tried running just 2X reg dual rank 4 gig chips in the first 2 banks and swapped with 2X reg dual 2 gig chips. same affect, windows becomes chopping and slow. put back in the 2X reg dual 512 chips and runs fine; add 2 more reg single 512 chips in the next 2 banks totalling 2 gig, runs fine. Appears that windows 7 is not happy with anything more than 2 gigs of ram...? I am running the latest bios available from Dell.

    This is a complete new install of windows 7 Ultimate 64 bit on a new static hard drive. windows shows the memory installed; but, when I add more than the original 2 gigs made up of 512 chips it gets slow and dragging a window across the screen is choppy and frustrating. Machine is set up with 2x Xeon 3.8GHz processors. It should be a beast!!! but barely a poodle when more memory is added. it surfs the web fast with the 2 gig; but, I need more memory to run Solidworks Cad. There must be a driver or setting that I have missed. the machine is really empty except for Nvidia Quadro FX3400 video card.
    this is the first time I have used this sight... hope this finds someone that has over come this problem. I really would hate to put it back to XP.
    Thanks,
    J

    This is a Dell Precision 670 which should be able to handle 16 gigs of ram (WinXP). Dell refuses to help because this machine is not windows 7 compliant -that is NOT my fault! It is running windows 7 fine on 2 gigs and running windows upgrade advisors does not find anyting wrong. This is also my first DELL..

The problem is the old NVIDIA QUADRO FX3400 graphic card. Its last drivers from Nvidia are not fully compatibles with WIN7 64BITS and more than 2 GBs. I have just installed a new low cost NVIDIA Geforce GT610 and now my old computer flies!!!!!

If it's Windows 7 32bit it has limits on the amount of ram it can use.
Google it and see.

Need image of jumper settings for l7s7a2 rev 1.1 motherboard

Elitegroup Computer Systems (ECS) Support > ECS L7S7A2 > Main Support page,

http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?CategoryID=1&DetailID=267&MenuID=24&LanID=0

Click on Download.
(Features /Specification / Download / Support / FAQ / etc)

Click on Manual.
(Driver / BIOS / Manual)

Scroll down a little, click on the country name nearest yours, next to the Green Down Arrow.

A small window will come up on the right -
Opening l7s7a2_eng11a.zip

Make sure there is a Green dot in the small circle, to the left of - Save File.
If there isn't; left-click in the empty circle to the left of Save File.
Now go below in the window, and click on OK.

A small window will come up on the left.
Allow the file to fully download, then DOUBLE-click right on the file name.
In the next small window click on - Extract all files, to the far left.

In the next three small windows click on Next, Next, and Finish.
Finally in the last small window, DOUBLE-click right on the file name, next to the red Adobe PDF icon.
(L7S7A2_en...)

There is the motherboard manual, and the jumper settings.

IF, you cannot open this Zip file, suggest go to 7-Zip, download, and install. It is a free 'un-zip' program.

[ A Zip file is used to send large amounts of information more easily.
A Zip file is a compressed file.
You need to 'un-zip it', or uncompress it.

Requires an 'Un-zip' program.
WinZip usually comes with Windows, but may only last so long, because it is a trial version.
7-Zip is one of the free unzip programs, NO trial.
I use it ]

[NOTE*
I DOUBLE-clicked on the file name - L7S7A2, and a warning 'Squawk Box' came up from Microsoft.
Click on Run. It is OK I assure you.

[ Small primer;
Microsoft assures users that the program they are about to use, is free from Malware. (Virus, spyware, etc)
To do this they check the program out, and certify it to be OK.
This cost $$$$$$ for the software manufacturer.

Costs for the main program check, and EACH time a user downloads the software.
This = NO to most software manufacturers.

Most of the time the software is free, WHO in their right mind is going to pay each time a user downloads it? I wouldn't.
Also if I am a reputable software company, or pre-built computer company, I wouldn't either. ]

IF, somehow you cannot download the motherboard manual:

Motherboard oriented as it sits mounted in the computer case;
Processor to the Top, Ram Memory slots to the Right, 5 white PCI slots to the Bottom;

1) To the Left side of the Processor socket is a jumper.
FIDJP1

CPU (Processor) Ratio Selector
(Multiplier)

Two columns of 5 contact pins.
Contact pin on the Bottom/Right is Pin 1.

Pins on the Right side are numbered ODD.
Pins on the Left side are numbered EVEN.

Starting on the BOTTOM of the Right side, going towards the Top;
Pins 1, 3, 5, 7, and 9.

Starting on the BOTTOM of the Left side, going towards the Top;
Pins 2, 4, 6, 8, and 10.

Jumper on pins;

A) 1 and 2 - BIOS checks the Processor out, and automatically sets the Multiplier. (CPU Ratio Selector)

B) No jumper used -> 10.5
C) Jumper on pins 9 and 10 -> 6.5
D) Jumper on pins 7 and 8 -> 8.5
E) Jumper on pins 7-8, and 9-10 -> 12.5

F) Jumper on pins 5-6 -> 9.5
G) Jumper on pins 5-6, and 9-10 -> 5.5
H) Jumper on pins 5-6, and 7-8 -> 7.5
I) Jumper on pins 5-6, 7-8, and 9-10 -> 11.5

J) Jumper on pins 3-4 -> 10.0
K) Jumper on pins 3-4, and 9-10 -> 6.0
L) Jumper on pins 3-4, and 7-8 -> 8.0
M) Jumper on pins 3-4, and 7-8, and 9-10 -> 12.0

N) Jumper on pins 3-4, and 5-6 -> 9.0
O) Jumper on pins 3-4, 5-6, and 9-10 -> 5.0
P) Jumper on pins 3-5, 5-6, and 7-8 -> 7.0
Q) Jumper on pins 3-4, 5-6, 7-8, and 9-10 -> 11.0

The JP1 jumper is to the Right of the bottom white PCI slot.
(No.5 PCI slot)

3-pins going across in a row.
Pin all the way to the Right; is Pin 1.

Starting from the Right side, going towards the Left;
Pins 1, 2, and 3.

Turn computer OFF.
Put a jumper cap in Pins 2 and 3 for 5 seconds.
Remove the jumper cap, place back on pins 1 and 2.

Resets CMOS memory.

Just in case you are referring to the Front Panel header;

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires go to, is the Front Panel header.

The Front Panel header is to the Right of the CMOS battery, and is located next to the right outside edge of the motherboard.

Two columns of pins.
IF, I am reading this correct; 5 pins on the Right side, 4 pins on the Left side.

Pins on the Right side are numbered ODD.
Pins on the Left side are numbered EVEN.

Starting on the BOTTOM of the Right side, going towards the Top;
Pins 1, 3, 5, 7, and 9.

Starting on the Bottom of the Left side, going towards the Top;
Pins 2, 4, 6, and 8. There is NO Pin 10.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive connection.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

C) Pin 9 is N/C. Not Connected. It is Reserved. (Probably 5 Volts for the factory to test )

D) Pins 2 and 4 are for the Power On LED. (Light)
Pin 2 is for the Positive wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

F) There is NO Pin 10.

For additional questions please post in a Comment.

TRICKS AND TIPS ON HOW TO ACCESS THE BIOS/CMOS WHENEVER YOU FORGOT THE PASSWORD

BIOS PASSWORD ARE USED TO SECURE YOUR COMPUTER BY PREVENTING OTHER USERS TO ACCESS YOUR COMPUTER'S BIOS SETTING OR MAKING IT UNBOOTABLE REQUIRING PASSWORD.


But in some cases, some people forgot the password.

HERE ARE THE TRICKS AND TIPS ON HOW TO ACCESS THE BIOS/CMOS SETTING WHENEVER YOU FORGOT THE PASSWORD.

SOLUTION1. RESET THE BIOS PASSWORD USING DOS COMMAND PROMPT.

1. Go to start menu and choose RUN. For other operating system like Windows 7 and Vista, just use the search bar and type the command prompt. Right click mouse and run as administrator.
2. type the word "debug" and press enter
3. type the code "-o 70 2e" and press enter
4. type the code "-o 71 ff" and press enter
5. type the letter "q" and press enter
6. type the word "exit" and press enter
7. try to restart your computer and it will remove the bios password.

SOLUTION 2. TRICK THE COMPUTER TO GENERATE BIOS PASSWORD.

Some computer can generate bios password when you enter 3 different incorrect bios password. Below message will appear:

Password check failed
Fatal error...System halted.
CNU9117K31

Use the last line as password. CNU9117K31

SOLUTION 3. USE BACKDOOR PASSWORDS


AWARD BIOS
AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, 01322222, 589589, 589721, 595595, 598598, HLT, SER, SKY_FOX, aLLy, aLLY, Condo, CONCAT, TTPTHA, aPAf, HLT, KDD, ZBAAACA, ZAAADA, ZJAAADC, djonet


AMI BIOS

Epox - central
Freetech - Posterie
IWill - iwill
Jetway - spooml
Packard Bell - bell9
QDI - QDI
Siemens - SKY_FOX
TMC - BIGO
Toshiba - Toshiba


In TOSHIBA BIOS, just hold left shift key during booting process.

For IBM APTIVA BIOS, press both mouse repeatedly during the boot.

SOLUTION 4. CLEARING THE CMOS JUMPER OR DIPSWITCH SETTING.

Go to your motherboard and look for jumper should be located near bios chips or near the battery. THere is usullay 3 pin switch two of them covered with this jumper.

Procedures :

1. Turn off your computer.
2. Unplug the power cable from the power supply unit.
3. Wait for 30 mins to be safe that your motherboard is fully discharged.
4. Locate the jumper.
5. If there is 3 pin switches, the jumper shows would be in 1-2 position. Just place it in 2-3 position with a few seconds and then return it back to normal position 1-2 position.
6. If there is only 2 pin switch, just remove the jumper with a few seconds and then place it back to normal.
7. Connect all the connection and restart your computer. It it will reset the bios setting.

SOLUTION 5. REMOVING THE CMOS BATTERY

If the jumper switch solution doesn't work, try this solution by removing the cmos battery.

Procedures:

1. Turn off your computer.
2. Remove power source cable.
3. Go to your motherboard and remove cmos battery.
4. Wait for 30 mins or more before returning it back.
5. Place the battery back correctly
6. Plug your power cable and start your computer and it is done.

GOOD LUCK AND I HOPE THIS WILL BE HELPFUL FOR OTHERS.

During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS
after you make any changes in BIOS press Esc then press the F10 button save to cmos to restart
cmos is located in BIOS

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don

    Computer turns on but no display/cpu_fan slot not working.

    The four-pin CPU fan connector is the same as the three-pin (red is for voltage, black is ground and yellow for the rpm reading) but also adds a blue wire used by some BIOS sets to adjust the RPM speed of the fan. The three-pin will fit into a four-pin connector without modification, using a jumper is DEFINITELY not recommended as it could short your board.

    If your system has the four-pin fan, and it boots and runs without error, it may be that your CPU is running cool enough that the fan is not needed at the time. Check your BIOS for a hardware monitor to see the actual CPU temperature. Also, you may have added utilities in Windows to give the fan speed and CPU temperature in real time. You may also notice the CPU fan kicking in when doing CPU intensive operations (virus scans, etc.)

    The four-pin fan would run from a three-pin connector but would always run at full speed because the RPM Adjust signal is not present.

    Wd800jd sata hard drive not recognized in bios on boot up

    Hi, A couple of ideas: 1. There are 3 versions of this motherboard: Dragon Plus, V1.0 & V2.0, perhaps your BIOS needs an update to be able to recognize the new HD. This of course would require flashing; 2. There are two variations of a WD SATA hard drive: Serial ATA amd Serial ATA II; 3. Re Jumper settings: the eight-pin jumper block is only used to enable power management on the drive. There are no master/slave settings since there is only one drive per cable; 4. If you are fresh installing Windows on it, you need to press F6 when asked by the Windows Installer and follow on-screen instructions. Hope this be of some help/idea. Post back how things turn up or should you need further information.
