Memory Management bsod

Hey guys, I recently built a new rig and everything seemed to be running smooth until I got 4-5 completely random blue screen crashes. Most of them were Memory Management bsod's but I got 1 pfn_list_corrupt bsod as well.

I ran memtest86+ for 7 passes and got no errors.


Specs are:

-ASRock H61M/U3S3 LGA 1155 Intel H61 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard
-Patriot Gamer 2 Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)
-SAPPHIRE Radeon HD 7770 GHz Edition 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP
-Intel Core i3-2120 Sandy Bridge 3.3GHz LGA 1155 65W
-Rosewill HIVE Series HIVE-550 550W Continuous @40°C, 80 PLUS BRONZE
-Western Digital Caviar Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5"


All of my ram settings are on Auto. Is there any changes that need to be made here?

I have all of the latest drivers. Any idea what could be the cause of this? Ill post more information when i get a chance.

If i cant figure it out ill probably just end up buying new ram and waiting to see if bsod's happen.

Also a quick thing i noticed concerning memory settings. When I ran memtest it said my CAS setting was 7-7-7-20 and (DDR3-1064)

And on the memory tech specs it says Enhanced Latency 9-9-9-24 / DDR3 1333 (PC3 10666). 1.5V / 1.65V


Are my settings incorrect by having it on Auto? And could this be causing my blue screens?

I'd be more inclined to suspect that you may possibly not have enough power. Are you sure that 550 watts is enough for that rig??

Check out that psu calculator and I think you'll see that you're right on the line of barely having enough power.
I think you're safe with your memory settings on automatic. Best of luck!

Is not enough power a normal cause of memory management blue screens? thankyou for your input.

Honestly 550W should be plenty with just a 7770. It's not exactly a power hungry card, nor is the 2120 a power hog of a CPU. You could get away with 450W with that, I would imagine.

Does sound like a RAM problem, but since it passed memtest, I'm not sure. Manually change the Speed, Timings and Voltage to what they're rated at, in the BIOS to see if that helps. (1333, 9-9-9-24, and 1.65V (although it says 1.5 too, but that may be the problem)

yes, I agree....the psucalculator came up with a estimate of 466 watts. His psu is rated at 550 watt. i just think thats cutting it close.

Just checked, and that PSU IS a little weak on the 12V rail with a max wattage of 456W available. I still don't think that's the problem though. I think the setting in the BIOS for the RAM may be wrong.

Edit: Cool.

How would i set it to 9-9-9-24 in the bios? And should it be set at 1.5 volts or 1.65 volts? It said both voltages on the tech specs.

I see the ddr 1333 option.

use cpu-z it read the ram speed also under spd it have the rated speed for your memory. on most ram the top speed is going to be under the xmp profile. also put one dimm in at a time and run memtest and see if it bsod. sometime you can have one dimm with an issue. it under DRAM Timing Control set it to mal and you can set you ran timing up there.

I'm not sure because I don't know how the BIOS is on that board, but it will be in an advanced settings menu somewhere.

And on the voltage, I saw that too, and that confuses me, as well, but try 1.5V first. I think it may ultimately be that the voltage NEEDS to be 1.65V, but if it will work at 1.5V, that's the best (especially for a SB CPU).

small update, I changed the timings to 9-9-9-24 instead of 7-7-7-20 and left the voltage on auto which is 1.545 volts.

However when i changed the DDR3 option from 1066 to 1333 the computer always fails to boot 3 times before working so I put it back on 1066. Not sure why that happens. Im gonna see if the timing change alone fixes my bsod's for now.


Another thing to add, not sure if this is just general useless info but all my BSOD's say caused by driver: ntoskrnl.exe

Yeah, I think the voltage is gonna need to be 1.65V. 1.65V for 1333 seems a bit high though. It might actually be worth just buying another, different, kit, at this point.

I bought new ram and a new HDD that im currently installing, everything seems to be running smooth. I didn't get all the windows update errors i was getting last time (i believe the HDD had issues as well).


Thankyou DJDeCiBel for all of your help and input, much appreciated.
