Windows 7: BSOD on 64Bit while 32Bit runs fine

BSOD on 64Bit while 32Bit runs fine

Hello,

(Sorry for my bad english)

I really need help on this one.

3-4 Month's ago a friend of mine made me an custom build computer.

now from the beginning the computer looked fine to me after a couple of hours playing games it started acting wierd shows programs suddenly stopped working and gave me BSOD's in the beginning it came every 3-5 hours then after a few days i had 5 BSOD in 20minutes

i reinstalled windows a couple of times but still the same problem.

**Until sunday 8-9-2013 ** i whas sad about how many blue screens i whas getting again so i decided to reinstall the system once more.
But this time i accidently installed Windows 7 Professional 32Bit instead of 64Bit the computer i found out i had 32Bit when trying to update my GPU with 64Bit it told me it doesnt support so i looked in DxDiag and yes i had 32bit.

But now the computer seems stable for 5 almost 6 days straight no errors no BSOD nothing just stable like a good computer should act.

(now straight to the problem) In my oppinion the one of the RAM Sticks is broken
Yesterday evening i ran Memtest86 for 20minutes OVER 800+ ERRORS

(RAM = 2 X 8GB patriot Viper 1600MHZ DDR3)

Test 2: Pulled 1 Ram Stick out left the other in the computer and let it ran for over 11 hours 4 passes it showed my within the first 2 hours i had 186 errors and after 11 hours i had total 386 errors

(Total 386 Errors in RAM Stick 1)

Test 3: before i go to my work i stopped the first test shut off the computer pulled the RAM stick out and putted the other in i ran it for 10-11 hours straight 3 passes with 0 errors

(Total 0 Errors in RAM Stick 2)

i do think a 1 stick is broken because of the errors i gave

but why does windows 7 32 bit seems stable .

(in my opinion the good Stick whas on channel 1 and because windows 32bit doesnt use more then 4GB RAM so 8GB on 1 Stick is far enough for 32Bit so it never used the broken stick on channel 2.

and when using 64Bit the computer uses both RAM Sticks to give optimal performance and it only gives me BSOD'S

(Sorry for my bad english)

Let me know what u guys/girls think of this and maybe help me out.

You need to post it following the Blue Screen of Death (BSOD) Posting Instructions. Without seeing the necessary data, nothing will be a good idea.

If you are having ram errors, the ram needs to be tested to make sure it is the ram or the board dimm slots. Run Memtest86+ in each slot for 8 passes or until errors appear. If you see errors appear, you can stop the test, it has failed. There should be no errors. Run all sticks, 1 at a time in each slot. If sticks pass in 3 slots but fails in 1 particular slot, the the motherboard dimm slot is bad. If a stick fails in all slots, the ram is bad. If it is the ram, contact Partiot memory, for an RMA, but have them replace both sticks, as ram is made and tested as a kit. Most manufacturers make and test 2 sticks to run together well. Sometimes, even ram of the same make, model and size will not run together well, that is why you want a kit. Patriot will understand that.

Each stick in each slot. That's the only way to tell if the ram is bad or the dimm slot is bad.

Ok Essenbe what i did sofar.

I got 4 DIMM SLOTS like this

CHANNEL A 4-2
CHANNEL B 3-1

you told me to test each stick on each slot well i used 2 dimm slots 1 and 2

1 RAM Stick gave 0 Errors on 2 DIMM Slots


the other RAM Stick Kept gaving Errors on both DIMM Slots within 2minutes already 48 Errors



So i am pretty sure now that one Stick Broke and ill have to get a new KIT as a waranty because the sticks are like 4 month's old:O

I'm Not sure about Patriot memory, but most ram has a lifetime warranty. I know G skill and Corsair does.

But could this be the problem of why I get BSOD on 64bit and 32 bit stays stable??

Honestly, I can't answer that, I don't know. 32 bit will use only 3.5-3.8GB of ram. In theory, if it is using that ram from the good stick and none from the bad stick, I guess it is possible. I would follow the posting instructions Arc gave out in the link in Post #3. Run that test and let them see if they see any other indications. I know that even if you have other problems, the ram has to be taken care of first. Is the ram installed in the slots recommended in your manual for the motherboard? Always install ram in dual chanel mode, which usually means in the same colored slots. It will usually be slots 1 and 3 or 2 and 4. You could try reversing the slots the ram is in and see if that causes problems. I'm not saying it will, but a test to see if that is a possibility.
