Slow ram benchmarks?

post #1 of 7
Thread Starter 
Hi. Recently I ran two benchmarks for memory, PerformanceTest and MaxxMem. Both gave me what I would think are poor results for my system. PerformanceTest puts me below almost everything else.







Does anyone know what the problem is?

I have a GA-990FXA-UD3 rev 4.0 motherboard.

Well, I ran Aida64 and the results were completely different. So crisis averted, I suppose.

MaxxMem is single threaded, and this results in the differences shown.

^This, but the only time I can tell a difference compared to the i7-3770k we have at home is in synthetic benchmarks (The gap is huge). Perhaps I don't use applications that demand fast memory performance though. Does gaming count in that regard? Obviously for vram but I mean cpu memory performance.

With an intel chipset the hardware prefetching have a big impact on the Maxmem benchmark , not so big in aida 64 .
Mayby the Maxmem is bypassing the AMD hardware prefetcher and get lower results , what this meen in real life i am not sure smile.gif

Means nothing in real life honestly. 13Gbps read and write speeds to 25gbs will be hardly noticeable. Big difference but hardly anything you would notice besides benches.
