mem test time

[john3850]

I running mem test in windows on 1155 at 4200mhz with 8 megs memory and test is less then half done in 40 minutes.
Running 3 test with 2000meg and 1 test 1200meg.98% memory used.

When I ran this same mem test on a 1356 at 4200mhz with 6 megs this test is done in a third of the time.
Why does it take longer on a 1155 setup.

My guess would probably be dual-vs-tri channel, or perhaps somehow your settings were different, or perhaps the memory test version between computers is different?

1. Less memory to test (6 vs 8GB) 25% reduction of job
2. More memory bandwidth (triple vs dual channel) 50% more memory bandwidth

should be done in roughly half the time assuming memory timings and frequency are the same.

1155 mem test took 90 min.
The 1356 also faster gskill Pi memory
Need to see if there is a later mem test
