| Why are you baffled? You know the cause, its your memory. If it was fine before you upgraded then bad after the solution is simple. Is the corsair also 2700, different brands of ram have different timings and have the possibility of messing up because of incompatibility.
Try removing the 256 Kingston and running that. If that fails remove the kingston alltogether with just the corsair. If that runs then try the Kingston alone (both 256 and 512). If that works then decide what you want to do, little more kingston or less with the corsair, but you should also check their timings, the lower they are the faster your memory is, so if you can't have a gig (both 512s) then go to your system bios and check which set is lower (if either work indepentantly) and use that.
Any computer person would tell you its not wise to mix brands of memory, while it doesn't always cause problems the chance is pretty high and unnessecary when you can just get the same brand. |
