RAM problem maybe...

[MountainKing]

I just decided to beef up my e6600 and add 2GB RAM to my current 2GB config which runs in dual channel configuration (1GB Ram x2)

My Ram is Kingston DDR2667 and I bought 2x 1GB Kingston 667 memory from ebay second hand. Running Memtest on windows produced like 6 errors at around 70% before I stopped the test.

I figured something not good.

Here is what I did.

i) Downloaded bootable ISO of memtest and individually tested each memory slot. Test was run for 2 passes on each slot INDIVIDUALLY. No errors detected.
ii) Installed only the newly purchased second hand RAM and booted on Windows and ran HDI memtest. No errors here also.

Is this a faulty RAM or some RAM modules mismatch?

PS: When I was running the full test on 4GB, even with the test causing test errors, I didnot experience any PC crash or freezes etc.

Your input is appreciated guys.

I try to avoid using 4 sticks like the plague. Try opening your timings. It sucks because it takes such a long time to diagnose this and find the right timings that wont completely cripple your performance, it will have you wondering how much money is your time worth.

Hum, will those errors cause system crashes/lsot data if the system actually uses the RAM where it is 'acting up'? Timings will help you think? How much of a performance hit are we talking about?

Ok. I did some more tests. Ran memory test on both newly purchased RAM overnight. No errors. Again I run into errors when I get all 4 modules running.
Need some pointers.
1) How do I loosen up timings?? (It reports 5-5-5-15 in CPU-Z)
2) My windows is Windows 7 32 Bits and windows reports RAM @ 3.5GB ( I doubt that is the problem though)
