Motherboard: Abit IP35 Pro socket 775
Power Supply: PC Power & Cooling 610W with 49A on the +12V rail.
Processor: Intel Core 2 Duo E8400
RAM: 4 GB Corsair DDR2 SDRAM―4 sticks.
The FSB is at 400 MhZ clock speed and the RAM is at a 1-1 ratio, which puts it at DDR2 800 MhZ.
The cpu is then overclocked to 3.6 GhZ
Video Card: PCIE EVGA 9600GT
Due to my computer freezing(mouse and keyboard would not work) a couple of times recently, and due to BSODs about once a month which occur in both XP and Vista, I had reason to believe that I should check the RAM. I ran Memtest and it found about 4 errors, all on Test 5. This was after about 1.5 hrs. running Memtest. I then went back into the BIOS and changed the FSB back down to 333 MhZ, so that the RAM was then running at DDR2 668 MhZ. I ran Memtest again for 5 hours. There were no errors ! I then went back into the BIOS and changed the FSB back up to 366 MhZ, which makes the cpu run at 3.3 GhZ and the RAM at DDR2 732 MhZ. I ran Memtest again for over 2.5 hours. I got no errors ! It went thru over 4 passes. I then restored the overclock-changed the FSB back up to 400 MhZ, which makes the cpu run at 3.6 GhZ and the RAM at DDR2 800 MhZ. I ran Memtest again for over 2.5 hours. Again there were no errors ! This led me to believe that perhaps the errors were due to the RAM running at DDR2 800 MhZ. To verify this, I changed the FSB back up to 400 MhZ, which put the RAM at DDR2 800 MhZ. I ran Memtest again for over 2.5 hours. But there were no errors again. I left the FSB at 400 MhZ, and the next day I ran Memtest again. This time it found 2 errors, again all on Test 5. Again I then went back into the BIOS and changed the FSB back up to 366 MhZ, which put the RAM at DDR2 732 MhZ. I ran Memtest again for about 6 hours and it went thru 9 passes. There were no errors again. I am now at a loss to determine whether one or more sticks of RAM are actually faulty.

I think what you should do is first, leave them at their stock frequency (they are not designed to run faster then stock) and test them one at a time. pull out 3 and just test the one, and once done with one, swap it out for the next. and see what happens then.

Now you know why I go 2X2gig instead of 4X1gig. Any time you fill all of the memory slots stability suffers. Sometimes you find disclaimers that guarantee memory speed/timings with only 2 slots (3 on X58 motherboards) populated.

You might edge up memory voltage as well to stabilize things.

Thanks for your replies. The RAM is not being overclocked-it is running at its stock speed of DDR2 800 MhZ. I suspect that using 4 1 GB sticks instead of 2 2 GB sticks could be part of the problem. Right now I'm keeping the FSB at 366 MhZ and I'll see what happens.

ive got no issues with stability and I have all 4 slots filled. in fact, my system runs better now then it did when i only had 2 slots filled. when I had only 2 slots filled the computer wouldnt boot right it would turn on and not do anything i would have to hit the reset button and it would then turn on, I filled the other 2 slots and voila that problem went away. whats important is they all need to run at the same voltage and have the same timings. :D

I thought about increasing the memory voltage, but haven't tried it yet. As I said before, the RAM is not being overclocked and I had the voltage at 1.9; Maybe I'll try 2.0
patriot09: For 4 sticks being stable, etc., I think that what motherboard you are using might have something to do with that, though it is surprising that you had probelms when only 2 slots were filled. Did you make sure they were in the correct slots for only 2 sticks ?

what voltage are they supposed to run at? and what speed is the FSB supposed to run at? if everythings at stock, (running the way the manufacturer states they should, speed, voltage, etc) then everything should run properly, if its not then theres likely a hardware problem.

<<The cpu is then overclocked to 3.6 GhZ>>

The fact that you have previously been running the system in an overclocked status...makes it possible (IMO) that something has been damaged.

I don't claim to know, but I believe that there is a reason for the standard warnings which accompany any overclocking of the system. Others here have more experience/knowledge about such.
