Windows 7: BSOD in Windows 7 Pro 64 bit Error Memory_management 1A

There are two possibilities:

1. You have one or more faulty RAM chips, or
2. You have faulty RAM slots on the motherboard.

You now need to do the following:

1. Unplug all RAM chips, except for one.
2. Run MemTest86+ again for a mimimum of 8 passes
3. If no errors are encountered, take the same RAM chip and insert it into the next RAM slot on the motherboard, and repeat step 2.
4. Repeat for all motherboard RAM slots.
5. If no errors are encountered it means that this RAM chip is OK, as are the motherboard slots.
6. Repeat step 2 for all RAM chips in one of the motherboard RAM slots, until you find the defective RAM chip.

Found bad RAM stick! Last question (:

So, I ran the test with the bad memory stick and sure enough I got tons of errors instantly in all 4 slots on the MoBo.

Put in the other stick of RAM and boom, perfect (: Looks like the problem was the memory stick.

If I want to replace it, should I buy the exact same kind?

I had 2 of the 4 GB Kingston HyperX DDR3 Genesis. Do I need to make sure to buy 4 GB of the exact same kind? Or should I just get better stuff and buy 2 new sticks. Also, with my system, would be make a difference to get a couple 8 GB or is that just total overkill (I know this doesn't fit the 'problem' part of this board, but I really do wanna 'fix it right' to prevent problem and quality matters to me).

Important Note: Thank you so much for helping me through this BSOD problem. I will close this thread as solved as soon as a couple days pass (never hurts to be careful). You guys are awesome and I appreciate it very much.

Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Follow the Part- three: If you have errors part of How to Test and Diagnose RAM Issues with Memtest86+ . Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
testSlot1Slot2
RAM1ErrorError
RAM2GoodGood
It is a RAM, a bad RAM.

But if you have got a result like that:
testSlot1Slot2
RAM1ErrorGood
RAM2ErrorGood
It is a motherboard issue. The particular slot is bad.

If you want to buy new RAM, better it is to buy a new KIT. Make it sure that the particular RAM you are getting supports your motherboard, and that's all.

If you want to buy a single stick only, match the new one's FSB/MHz timing with the existing one. Otherwise it will yield the average RAM quantity only.

Thank you!

Arc and Golden,

You are both awesome, thanks so much. The computer is working and the faulty RAM has been removed.

The other Stick of RAM passed in all slots so all the DIMMs are good (: The other bad RAM failed in all slots.

I will order up some new RAM and everything seems good to go.

Again, I will close this thread in a couple days (assuming no BSOD) and again THANKS
