2 sticks of crucial @ 141FSB 1 stick @135?

Well i tried to take out my second 256mb stick to see if i got higher then 141 with just one stick on my KG7 RAID, I noticed that I got a blue screen before loggin onto the logon screen on windows 2000, this was the blue screen that said if this problem keeps on happening make sure u unistall any newly installed hardware... Now i tried 2.79 V on the one stick @ 136+ FSB nothing, i tried to lower the Voltage still nothing... cas is @ 2, same as it was with the two sticks everything is the same as it was with the two sticks on the bios, now what could be happening here?
The both sticks had DDR heat spreaders... on them the ones by thermalake, no Fan ontop tho =(

i heard those heat spreader thingies trap heat, might want to try removing them and see if it helps.

yes indeed it did, although I can't get that far, I'am thinking that there is a problem with the air flow, going to have to get some rounded cables see if the ram can be OC higher.
