I'll work on that tonight.
Some have questioned MaxxMem so I just ran it. Confusing thing about that one, running it with all the regular ID's the results all appear to be within the normal deviations. But when I ran it under the Bubba Hotepp Vendor ID all the results were within normal deviation except latency which suddenly dropped. That has me scratching my head.
I have no idea how the vendor strings and whatnot you are looking into work, but I do know that the MaxxMEM score does not seem to reflect the real data bandwidth (throughput) when I compare the results from it to the results from other memory benchmark programs. These programs do not show all of the same data, so it is hard to do a full apple to apples comparison. But both AIDA64 and Sandra show some big increases in the results that can be compared directly to the MaxxMEM ones. Below you can see that MaxxMEM says I have 12 Gb/s of throughput, and Sandra says 19 GB/s. In the second screen it has the Sandra results for latency(can't open both benches at once), and you can see that Sandra and AIDA agree that my memory latency is around ~47 ns, and MaxxMEM says 54 ns. Aida says 20,000 MB/s memory copy rate and MaxxMEM says 16,000. Too bad AIDA does not have a bandwidth test, and too bad Sandra does not show Copy/Read/Write speeds. You can get all three of these for free at MajorGeeks, although the free version of AIDA blanks out some of the fields. It would be interesting to see what some Intel rigs will get when they run these same three side by side like I did here. From what I know a decent Intel rig should score around ~20-25 Gb/s on MaxxMEM, which if the same ratio (12gbs/19gbs= ~50% increase)were applied as what it is with an AMD that Intel rig should score 30-37 Gb/s on Sandra, and I know that can't be.
I became aware of this about a year ago when somebody brought it up on OC.Nuthouse. I did see some posts of Intel rigs scoring about the same on all 3 tests, and for AMD rigs you can see for yourself the difference between the scores of these benchmark programs above. I am sure that particular thread was shoved down the memory hole as is the case with anything that might show AMD products in a good light on that site that happens to be plastered with Intel ads from top to bottom. Knowing what I know now about OCN I have to wonder if the "MaxxMEM clubs" and seeing MaxxMEM always being pushed as the memory benchmark program to use by the "helpful" staff is just a coincidence.
