Question
Blue Screen Windows 7 - Memory_Management 0x0000001a
I am setting up a new system and I am having a periodic BlueScreen indicating a Memory Management issue. Have not picked up on a definite pattern as to when the BlueScreens occur, yet. Below is a copy of the Blue Screen info:
Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.48
Locale ID: 1033
Additional information about the problem:
BCCode: 1a
BCP1: 0000000000003452
BCP2: 000000000E7E5000
BCP3: FFFFF700010B1E70
BCP4: B2D0000164B9BC46
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1
Files that help describe the problem:
C:\Windows\Minidump\110609
C:\Users\<Name>\AppData\Lo
The system is as follows:
MB: ASUS P7P55 WS (BIOS 0403)
CPU: Intel i7-860, 2.8GHz
MEM: 4 DIMMs - G SKILL F3-12800CL9-2GBNQ for a total of 8GB
OS: Windows 7, 64 bit.
In reviewing the manuel for the MB I found a note that "Due to Intel spec definition, X.M.P. DIMMs and DDR3-1600 are supported for one DIMM per channel only." Not sure if this is an issue and presently running on only 2 DIMMs at the present time and waiting to see if the problem persists. There are also two BIOS updates since the version on my MB. Not sure if that may help.
I also ran MemTest86 before removing 2 DIMMs no problems after 2 passes. Will run more passes as time allows.
Any input as to the possible problem would be appreciated.
Thanks

I will update the bios in the AM and see how that goes.
According to the manual the memory I have is supported using 1 module inserted into any slot, 1 pair inserted into channel A1/B1 or A2/B2 slots (Blue or Black) or 2 pair inserted into all four slots. I originally had all four modules in and now I am running on only one pair in A1/B1.
I had similar problems when I switched to 64-bit a year or so back.
See here:

VISTA_DRIVER_FAULT with OUTLOOK.EXE.
all drivers up to date? ( check with: http://driveragent.com/sca
all software (specially office and os) up to date?
All drivers are up to date for windows and office. Still have not had a blue screen since removing two memory modules. Planning on running for a few days and then switching the two modules to see if the problem returns. If not will try all four again to see if the Blue Screen returns.
hopeleonie, what do you use to view the minidump files?
Another follow up. I have all 8GB of memory modules back in and it has been running fine for a full 24 hours. I probably just jinxed myself and the blue screen will show up after I hit the submit button. I did update the BIOS to the most recent version and also removed and reseated the memory modules. We will see of the next few days.
Another Blue Screen today... MiniDump is attached. I had just logged onto the system after a startup and was in MS Outlook

Can you test your harddisc ram and cpu for errors with: http://www.ultimatebootcd.
Memory Tests with: Memtest86
CPU Tests with: CPU Burn-in, Mersenne Prime Test & StressCPU
Hard Disk Diagnostic with: your Hard Disk Manufacturers tool. (Drive Fitness Test (IBM/Hitachi) works with most)
If evrything passes, I would try removing all of your component down to just the cpu and ram and see if that helps.
I have run every test I can find Memory, CPU, GPU, HD.... Nothing... Everything is working/tests fine.
As for hopeleonie's recommendation to strip down to just the cpu and ram - the blue screens are not persistent or repeatable. They will randomly appear, although typically twice, and then not occur again for along time - i.e. week(s).
hopeleonie - was there anything in the last two minidumps?
I am still working on this problem. I seam to be getting more BSD's the past few days and the BCCodes are all over the place. I ran Memtest86+ again this morning when I left for work and upon return had many errors listed. The errors were from Test 6 - Moving Inversion and test - 7 Random Number Sequence. In the 5000MB and 6000MB range. All were Error Bits "00010000". I powered down the computer and I swaped the DIMM's in A1 and A2. I hope to see more errors and a change in the memory range or error bits. We will see...
Memtest86+ ran for almost 10 passes last night and not a single error...
This is getting frustrating. I was really hoping to pick up a bad memory stick and a possible solution to the problems I have been encountering. It could have been a poorly seated memory stick but I am expecting to have more issues soon.
hopeleonie - I have not had a chance to export the system and application logs yet but will try to get those to you this weekend.
Found a solution. I had also been emailing the memory manufacture and they came up with the most probable cause and solution. The ASUS P7P55 WS has a AI Overclock Tuner that will automatically adjust the BIOS memory configuration to get optimal performance. The problem is sometimes it was setting values that were unstable. By manually setting some of these values to a fixed value, that instability is less likely. Below is a list of settings that were recommended to be set manually. NOTE - The values listed below are for the ASUS P7P55 WS motherboard and G.SKILL F3-12800CL9D-4GBNQ memory I am using in my system. SETTINGS AND OPTIONS WILL BE DIFFERENT FOR DIFFERENT MOTHERBORDS AND MEMORY.
AI Overclock Tuner - Manual
CPU Ratio Setting - 21.0
BCLK Frequency - 133
DRAM Frequency - DDR3-1600MHz
DRAM Voltage - 1.60V
CPU PLL Voltage - 1.90V
DRAM Timing Control (submenu)
CAS Latency - 9
RAS to CAS Delay - 9
RAS PRE Time - 9
RAS ACT Time - 24
DRAM Timing Mode - 2N
All others can be AUTO
I hope this is the perminate fix and that this information can help others with simular problems. Points divided among all those you helped. Thanks again to everyone here at experts-exchange...

I would most definitely upgrade the bios especially if related to win7 before going any further.
