maybe the timing didn't set corectly,
have you check it?

Re: Memory dump after installing new ram

Your memory is PC2-5300 (667MHz) with 5-5-5-18 primary memory timings @ 1.8 volts.
What is the brand/model/version of your old memory, motherboard and/or system?
What operating system is installed?

Re: Memory dump after installing new ram

Old memory was Corsair CM2X1024-6400 1.90V ver5.2, 5-5-5-18 800MHz. (2 x 1GB). Gigabyte G31M-S2L Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz, Win 7 Ultimate Dual-Core. I hope this is enough information. Do I have to reconfigure BIOS?

Re: Memory dump after installing new ram

Some minor bios changes might be needed.
Your new memory has similar specifications to your old memory.
Do you still have your old memory to test with?

Before your remove or replace any memory modules or other hardware:

1. Turn off your system.
2. Turn off your power supply using the on/off power supply switch at the rear of your computer case. This switch is on the outside of the computer case.
3. Press and hold the front panel on/off switch for 10 - 20 seconds to discharge any residual power in your system.

• Remove one of your new memory modules, the module located farthest away from the cpu.
• Try booting with only one of your new memory modules installed in the memory slot closest to the cpu.
• Turn the power supply switch on and then start your system.
• Press the delete key to enter the bios.
• You won't make any bios changes right now, we just need to find out which bios version you are using.
• At the main bios screen, pressing F9 should display the bios information, along with some other information.
• Write down the bios information and then press the Escape key to close the information screen. The bios version will be F2, F3,...,F9 or F10F.
• Next press F10 to automatically save settings and exit.
• Boot into windows with only one memory module installed and see if your system is more stable.

IMPORTANT: Handle the memory carefully so that you don't damage it with a static electrical discharge.
I touch a bare metal screw on the inside of the computer case frequently to discharge any possible static charge while I'm changing hardware.

Let us know if your system behaves normally with only one memory module.

One of your new memory modules might be faulty.
It's best to test new memory with Memtest86+ before booting into windows.
We''ll cover the testing step later.

Re: Memory dump after installing new ram

I haven't made the physical changes yet to the machine but I can tell you for a fact that BIOS version is F10F. I know because I flashed the BIOS myself. I'll proceed with the changes you requested. BTW I had another memory dump and the blue screen suggested that I should change caching or shadowing in BIOS.

Processor Type Intel Pentium Dual CPU
Processor CPUID 06FD
Processor Speed 2.2GHz
Processor Clock 200MHz
Memory 2048MB
Model Name G31M-S2L
BIOS Version F10f
BIOS Date 6/1/2009
BIOS Part Number 6A79OG0V
LAN MAC Address 001D7D7FCB9B

Running the computer on 1 module as suggested and there seems to be no problem. It's no different from the time I was using 4GB except of course when I had 2 crashes while using the computer and the last time when I turned it on during the sign in window. Also I think windows has a memory test, does anyone know how to access it?

Turned computer on briefly this morning and it's sluggish with the 1 module.

Re: Memory dump after installing new ram

Check out step #4 in http://forums.tweaktown.com/gigabyte...tml#post295784, post #5 to provide a screen-shot. Your system should automatically set your memory to the optimal memory timings and voltages. The screen-shot will confirm this. EasyTune 5.0 for your system will show some useful information but isn't necessary.

Your system with one 2GB module shouldn't be sluggish. Have you ever loaded Optimized Bios default settings from the bios main screen? This is an important first step, especially after flashing your bios.

It looks like your bios doesn't allow you to increase or manually set MCH Core voltage. Sometimes the MCH Core voltage needs to be increased somewhat with 4GB of memory but this shouldn't be necessary with your memory running at stock memory timings at 800MHz speeds.

Replace your current memory module with the second module and see if you have any BSOD problems. You should set windows so that it doesn't automatically reboot when a BSOD occurs. Let us know the cryptic BSOD message and the error code which has the following format: 0x00000000 where the trailing digits will have a code that is a combination of numbers (0-9) and/or letters (A-F). There should also be some dump related information in the windows Event Viewer.

A web search on:
windows memory diagnostic
provides links where you can get information.

You should download MemTest86+ v4.20 to easily make a bootable floppy or cdrom to test your memory without booting to windows.

Re: Memory dump after installing new ram

I have reinstalled the 2 2GB modules yesterday. I had no problem yesterday or this morning. I turned the computer this afternoon and I got a BSOD. The BSOD message was as follows " A problem has been detected and windows has been shut down to prevent damage to your computer. PAGE_FAULT_IN_NONPAGED_AREA. ...... Disable BIOS memory options such as caching or shadowing.... 0x00000050 (0xFFFFF8A802B3F8F0, 0x0000000000000000, 0xFFFFF80002E, 0BFx0000000000000005). ....Dumping physical memory to disk: 100" That's what the message contained in an abbreviated fashion. Not to sure about the codes in parenthesis especially the last two because some of it was cut off from the screen. Also as a reminder the old memory was 800MHz and the new one is 667MHz. I will now proceed to look into the Optimized Bios default settings.
I loaded optimized BIOS default settings and afterwards computer started in windows but froze after I was doing a search on HDD. Second time the computer is now more stable. I managed to use windows memory diagnostic test and it seems there are no problems with ram. I will try to use MemTest86+ v4.20 as soon as I find a CD, would prefer to use a usb thumb drive but don't know how.. I have also updated my Sig but don't know how to display it the way you do. If you think I should post more info on Sig then please let me know.
I had another crash while web browsing and had more or less the same message except for the following "MEMORY_MANAGEMENT, Technical information *** STOP 0x0000001A (0x0000000000041790, 0xFFFFFA8003348630, 0x000000000000FF)".

Re: Memory dump after installing new ram

Boot into your bios.
Press CTRL + F1 at the main bios screen.
Enter the M.I.T. screen and make the following changes:

• PCI Express Frequency (Mhz) ------ [Auto] <--- set to 100
• High Speed DRAM DLL Settings ---- [Option 1] <--- set to Option 2

Do you see an option for changing (G)MCH voltage?
Press the Escape key to return to the main bios screen.
Press F10 to save settings and exit.

If these changes don't help, re-enter the M.I.T section and set:

• DDR2 OverVoltage Control ------ [Normal] <--- set to +0.10

Save settings and exit.

You can do a web search on:

• stop error 1A
• stop error 50

and read possible solutions that deal with win7 operating systems.

Let us know if these changes help.

Re: Memory dump after installing new ram

I was able to set PCI express Frequency to 100 but I didn't see High Speed DRAM DLL settings so I reset PCI express frequency back to auto and then set DDR2 OverVoltage Control to .10. I didn't see a setting for MCH Voltage. I was able to run memtest86+4.20 and it related 26,624 errors after 6 passes for over 7 hours. According to memtest86+4.20 ECC was disabled, I am not sure if that should be activated nor do I know how to do that. I have seen on other occasions that ECC parity should be activated. Anyhow I will use these settings and see if I get anymore BSODs. Also I have a triple boot system (win 7, vista and ubuntu) although the vista OS is not working because the drive for which it is located has not been installed. I mention this because when staring up the computer I am able to press delete in order to get to BIOS but I am not able to scroll up or down (arrow keys) to select another OS. I wonder if Optimized Bios default settings has anything to do with that since this problem arose when I made those settings. I will rerun memtest86+4.20. Got another BSOD last night with the usual errors.

Re: Memory dump after installing new ram

ECC memory is primarily for mission critical servers, not for consumer systems. I think that consumer products don't usually support ECC memory.

Memtest86+ errors indicate that there is possibly a hardware problem. Errors often appear when some bios settings aren't set correctly.

It's only necessary to run this test until one error appears, which indicates that your system isn't stable. Sometimes I've had many thousands or errors occur quickly when I was using memory that was good but my overclocked bios settings weren't correct.

There are three possible problems right now:
1) Your memory and motherboard aren't compatible.
2) You have one or more bad memory modules.
3) Your motherboard has problems, probably a bad memory slot, or failing chip.

I assume that your last test was with both memory modules installed. To narrow down the problem, you will need to test each module, one at a time in the first memory slot. Testing each module one at a time in the second memory slot might also be needed. Even if all of these individual tests run error-free, there still might be a stability problem.

You can try testing with "Fail Safe" bios defaults, but I have never seen this option help with stability. Your best bet right now is probably to contact Corsair tech support and provide them with the results of your testing. They might want your to RMA the memory to them and they will send you an identical replacement set or they might want you to use a different model of memory.

Memtest86+ is an excellent preliminary testing program. Additional testing with Prime95 or similar stress testing programs is required to verify that your system is stable.

Re: Memory dump after installing new ram

I ran the test you suggested by testing each module one at a time on each slot. I determined that there is one module that consistently had errors. I will now proceed to RMA the module and/or set. At this point I don't think there was a compatibility issue nor a stability issue with the MB. I decided not to run Prime95 because I don't want to risk any problems with that app. I have never RMA a device like this before, any advice? Lastly do you have any advice on the keyboard issue?

[profJim]

Re: Memory dump after installing new ram

To RMA your ram, go to Corsair Tech Support and start with "Select your product type".
You should detail your testing. It should help if you include a link to this thread in your RMA submission.

What is your keyboard Issue?
What brand/model is your keyboard? Does it use a PS2 or USB connector?
