Windows 7 Blue screens

[DenvH]

Hi,

First off: it's not related to PR at all, but I figured someone might know what I should do..
My problem, I bought pc parts in September 2009 to build my own pc. With that I also bought Windows Vista Home Premium 64bits + Voucher.

Now my pc has run perfectly fine on Windows Vista, but ever since I installed Windows 7 I get random Blue Screens once or twice a day, all 0x000000 indicating hardware issues..

These are the 5 different codes I get:

• 0x00000024
• 0x00000050
• 0x0000007E
• 0x0000001A
• 0x0000003B

Now because of this instability I find my self doing the same work twice, which gets frustrating after a while.

Now I did contact the shop where I bought my components, and they advised me to send all of the parts back to their shop, but I'm not looking forward to do anything like that. So is there anything I can do to narrow down the problem and maybe send only 1 or 2 pieces of Hardware?

My specs:

OS: Windows 7 Home Premium 64bits..
CPU: Intel Core i7 920
CPU Cooler: Scythe Mügen 2
Main Board: Asus P6T
RAM: (2x) 3 kit OZ DDR3-1333 6GB (12GB in total)
Graphics Card: Asus Nvidia Geforce GTX295 1.8GB
Power Supply: SilverStone 1000Watt
Case: Antec 1200

And I got a 1TB HDD and 2 DVD burners.

Keyboard: Logitech G19
Mouse: Logitech G5
Monitor: Samsung Sync Master 2494HM 1920x1080

It's not overclocked, only changed the RAM controller to be 1333 instead of 1060..


I hope someone knows what I can do to narrow down this problem or even solve it.
Thanks in advance,

Dennis

1 - Re-seat all your hardware (start with memory), to check for good connections. Did you move any hardware around or add anything new when you put Win7 in?

2 - Notice you have 2x6GB kits. If you can remember which of the kits go together (as bought) put only 1 kit in, and see if you have the same problem.
Try the other kit, then carefully label up the sticks and find which one might be faulty.
My guess is when you take half your memory out you will stop getting the BSOD's.

3 - Do some research on your memory setup online, and check whether overvoltage or undervoltage is recommended, also are you setting any timings/voltages manually.

First off all, thanks for the reply

1 - I've tried this once, with the memory sticks but that was after I experienced BSOD 's.. And I've not put anything new in (yet), might buy an extra or new GPU in the future.

2 - I can give that a try, they have id numbers that match on all 3 cards (123438 - 1, 123438 - 2 ect) never tried to put only 1 set in, and I guess it doesn't make a difference since I only use 1,3GB idle + max 4GB for any program that isn't 64 bits so I'm going to try that for sure.

3 - I haven't set the timing's or voltages manually, as my cards did not come with any instructions and or numbers to do so. But I will get into that, you think I should look on the OZ webpage or my mainboard's page?


EDIT: I got another 0x00000024 today and it seems like 1 of my 6 memory cards has stopped working or has bad connections as windows now only detects 10GB of RAM..

EDIT 2: I looked up the Qualified Vendor List for Memory QVL on the ASUS P6T/windows 7 and this is what I found:

Vendor: OCZ
Part No.: OCZ3P1333LV6GK
Type: DDR3 1333
Size: 6144MB(Kit of 3)
SS/DS: DS
Chip NO.: Heat-Sink Package
TimingLable(Bios): 7-7-7(1066-7-7-7-20)
Voltage: 1.65
DIMM socket support: ●A*●B*●C*

A*: Supports two (2) modules inserted into slot A1 and B1 as one pair of Dual-channel memory configuration
B*: Supports three (3) modules inserted into the orange slots (A1, B1 and C1) as one set of Triple-channel memory configuration
C*: Supports four (4) modules inserted into the orange slots (A1, B1 and C1) and the black slot A2 as one set of Triple-channel memory configuration
D*: Supports six (6) modules inserted into both the orange slots and the black slots as two set of Triple-channel memory configuration.

It appears that my memory card does not support 2 tri-kits on this mainboard.. But for windows Vista 64 bits it says the same, only for 2,3 or 4 sticks at a time and it has run without problems.. so maybe I need to buy new RAM capable of doing 2 tri-kits on the P6T? That or I'll wait until the 4GB sticks get cheaper and go for 24GB of memory.

windows 7 has an integrated tool named "Windows Memory Diagnosic" you should try running this and see if it comes up with anything.

Alternatively: You could use a linux live CD and run "memtest" from its boot menu.

Also it really does seem, judging by your manuals entry that its not compatible with 12 GB of that brands RAM in tripple channel mode but it should at least let you use all 12 GB in single channel.
You should try to trade your current RAM with more compatible RAM at the store you bought it from.

Note: You should also make sure that the RAM is properly installed (the BIOS and Linux Live CD should recognize all 12 GB always). Then you should make sure that the kits are properly distributed (kit 1 on orange, kit 2 on black slots).

You can get a Linux Live CD here: Download Ubuntu | Ubuntu (make sure to select 64 bit version "9.1 desktop") - don't worry you don't even have to use linux its just for the memtest tool

I've tried this before, but it doesn't show results after the test.. So I'm going to try memtest and see what it comes up with.

I did put in the voltage for my RAM in the BIOS, it said: 1.5V standard, I've put it on the recommended 1.65V to see if it makes a difference. Maybe there wasn't enough Voltage going to the sticks or something..

I've pulled out one set of the ram and it has been working well for about a week now.

I'm going contact the store where I bought the cards and see what they can do, disappointed though that they didn't check if the system was going to work with the 2 sets of RAM, but at least I've learned something for my next build whenever that may be..

Are you saying that it's due to incompatibility between the RAM and the MOBO, or is one of the sticks broken?
What did memtest tell you?
