I am totally getting confused. Last night there were 0 errors on Memtest and today in just 20 seconds there were 55 errors. I removed the RAM and re inserted and it was again fine with 0 errors. When i keep the ram installed for some time (usually 7-8 hours) it will start getting errors and BSODs and Memtest errors. When I remove and re insert it is fine.
Motherboard- Gigabyte ex58-extreme
CPU- Core i7 920
RAM- Corsair DDR3 2GB x 3
Corsair SSD
Yes, as LW7 says, don't ignore a failed Memtest. You've got a RAM problem.
But don't read too much into the "reinsert RAM" thing. I think it is safe to assume that you are not doing this with the computer running! So you are shutting down, disconnecting power, and re-seating the RAM. That could simply mean that when you "cold boot" afterward you don't get any errors, but after it has been running a while the errors show up. That makes sense because when you cold boot all the RAM registers are "clean".
You can further test the RAM by installing one stick in slot A1 and running Memtest on it. Do the same for the other two sticks. If one stick shows errors and the others don't then you have your answer.
You can also try going into the BIOS and changing the Dram Frequency to 800 MHz as a test. Sometimes bad RAM will run fine at a lower frequency.
Keep in mind that the errors can also be caused by a faulty motherboard (RAM slot), power supply, or overheating. But most times it is just bad RAM.
Everything is random. If it shows errors it shows on all RAM sticks and all slots. But when I remove and re insert then for next 5-6 hours it wont show any errors.
replace the ram.
the person from whom i bought RAM asks me to send the stick that is bad. He says all cannot be bad.
While it is not likely that each and every one are bad, it is certainly possibile.
They cant simply just assume its not possible to happen.
Did you try TVeblen's advice?
Start in DIMM slot one and test each stick individully, and then to next slot?
If they all Fail in DIMM slot 1, but all pass in DIMM slot 2, its possibly a MOBO problem.
If some pass and the same ones fail regardless where they are its most likely a bad RAM module/modules.
If they all Fail regardless of location, it could likely be a MOBO issue, or all the RAM modules themselves are bad.
Although Ill agree all the modules being bad isnt likely, as I said earlier, it certainly is possible.
If this is the case, and you still have a warranty, I would make them replace the RAM.
Just out of curiosity, would you mind posting a snip of the CPUZ screen for the Memory TABs?
Just to rule out settings if anything else.
