Memory strange problems

Hello, I have problem with my ram, I have 2x2gb (OCZ 2x2GB DDR3 SDRAM PC8500 CL7.0 Gold Edition)
and whenever I use both of them I keep getting all kinds of BSOD. though if I use either one alone it runs more stable but still report errors when running memtest, that suggests that they are either broken, badly configured or not compatible with my mobo.

Strange thing is if I stick both and put bios all on default the PC wont even get to windows loading screen before getting BSOD.
Unfortunately im not experienced with bios enough to be adjusting things freely so some help would be greatly appreciated.

Also this problem started when I decided to install windows 7 x64, I had to install it using 1 ram stick otherwise it would crash the installation. only windows xp would install with both sticks (2x2gb). vista and 7 x84 would always crash. I think the problem is my settings in bios but I cant find anything about my ram on the net to try and fix this.

If you run MemTest86+ with each individual stick of RAM and it reports errors on both, then it sounds like there is a problem with either both your sticks of RAM or your mobo.

As for new RAM any DDR3 1600 should be fine. I usually stick with Corsair, OCZ, or Mushkin as brands.
 
processing (CPU) corruption can also cause these errors. memtest does not know the difference between a block of data that is corrupted by the CPU and written correctly to the RAM, vs a block of data that is processed correctly, but corrupted while being written to RAM. it can only really tell you that the data was corrupted at some point in the path.

since you said you are overclocked, the first thing to do is to set all clocks back to stock and retest. if the problem goes away, its not a problem with the RAM.
 
So i ran memtest84+ on both my ram separably and both show huge amounts of red text, count was over 6000.
Is it safe to say I have to get new ram? also is it a bad idea using pc until I get new ram? because it can stay on without crashing 5-60min. does it actually damage other parts and should I just keep it off until i get new ram?

so why should I get PCI1600 ram does it fit my rig that good? if you had to choose from here https://www.4launch.nl/shop/get/p-1...filter-PC16000-image-ja-levertijd-null-tax-in

which one should I take the one for 37euro or 45? is it worth paying more? I could pull out 70euro but tight on cash atm. maybe other?

I really apreciate all your help guys, because I dont have anywhere else to ask :)
 
First I would set your OC back down to stock and test each stick of RAM, then I would start bumping it up again and testing the RAM. It could be that the RAM or CPU cannot handle the OC you are doing.

It could also be a bad motherboard or powersupply.
 
Step 1: Dial back your OC to stock levels.
Step 2: Boot the system with 1 stick of RAM.
Step 3: Test memory at stock levels with 1 stick of RAM using memtest86+ or similar program
Step 4: If errors occur, replace the RAM, see Step A.
Step 5: If no errors occur, "slowly" start upping your OC again til errors do occur. If they occur after this, then your problem is probably the OC and you need to keep it dialed down at a point where no errors occur.

Step A: repeat steps 1-3. If no errors occur, then go to step 5. If they do occur proceed to Step B.
Step B: Try a different PSU. Repeat steps 1-3. If still getting errors proceed to Step C.
Step C: Try a different processor. Repeat steps 1-3. If still getting errors proceed to Step D.
Step D: Try a different motherboard. Repeat steps 1-3. If you are still getting errors proceed to place computer in trash bin and start all over from scratch.
