Hi,
I have a strange problem with testing my ram. I have the following ram (8 Gb in total):
2 x 4GB DDR3 XMP PC3-12800 / BLT4G3D1608ET3LX0 8-8-8-24 / 800 MHz / 1.500V
And the following CPU:
Core i3-4330
The ram can run @1600 Mhz or @1333 Mhz.
I have run allot of tests with this ram (all tests are run with both sticks installed on the motherboard, Asus H96M-Plus). All tests run fine with no errors. I only get the warning during the Hammer test about the High Frequency Row Hammer Bit Flips.
The funny thing is that the warning does not occur when I just do the Hammer test (without the other tests) when the ram is @1333 Mhz. The warning does occur when I do all the tests @1333 Mhz.
When the ram is @1600 Mhz the warning always occurs, either running just the Hammer test or all the tests.
The following warning (always at the exact same spot!) is issued:
Besides the above, I have also tested my ram with the Google Rowhammer-test (https://github.com/google/rowhammer-test). I have run the test for about an hour and no errors or warnings were issued.
So my question is, is my ram faulty (the ram is not older than six months) or is it some kind of bug?
Edit: I just noticed the warning always occurs exactly at the middle of the RunHammerTest, this is the complete log of just the Hammer test;
