chumanga Posted October 7, 2013 Share Posted October 7, 2013 Hi there, so im have a little doubt about the true value of memory benchmark, i have a phenom x4 965 and in windows 7 x64 it got some faster results in memory read and copy over windows 8 pro x64. The results is this: Windows 7 result Memory Read: 14500 mb/s memory write: 8000 mb/s Memory Copy: 12540 mb/s latency:67.9 Windows 8 results Memory Read: 10095 mb/s Memory Write: 7566 mb/s Memory Copy: 7963 mb/s latency: 69.6 So im in doubt what making this different results, maybe windows 7 showing it wrong, or windows 8 is the problem, or because my cpu is too old for the new benchmark. The L1,L2,L3 cache got some few variation only in some points. I make the test many times and the average is what show up. Thanks Quote Link to comment Share on other sites More sharing options...
Fiery Posted October 7, 2013 Share Posted October 7, 2013 What version+build of AIDA64 are you using? Did you use the same AIDA64 version under both operating systems? Thanks, Fiery Quote Link to comment Share on other sites More sharing options...
chumanga Posted October 7, 2013 Author Share Posted October 7, 2013 Hello, yes i used same version, aida64 3.20.2600. I just installed windows 8 x64 to test battlefield 4 beta, because dont run well in windows 7. Beyond aida64 i tested winrar performance, and there too i got worse performance compared to windows 7. Winrar performance decrease from 4000-4100 kb/s in windows 7 x64 to 3600-3700 kb/s in windows 8 x64. Using same version 4.20 x64 winrar. I dont know if matters, but i installed each OS in differente HDD, but them have same 7200rpm, windows 7 in 500gb segate and 100gb for OS partition, and windows 8 2tb seagate 200gb for OS partition So im confused, maybe windows 8 is a heavy OS?

Fiery Posted October 7, 2013 Share Posted October 7, 2013 Windows 8 shouldn't have such an impact on system performance. It could either be that your hardware configuration/setting has changed somehow (due to a BIOS update for example) between the two operating systems. Can you please post a screen shot of the Cache & Memory Benchmark Panel, showing all system parameters and all memory/cache benchmark results? (under Windows 8) Quote Link to comment Share on other sites More sharing options...
chumanga Posted October 7, 2013 Author Share Posted October 7, 2013 Let me say something, im not expertise but i understand about overclocking and hardware setup like cpu frequency, Northbridge frequency, memory frequency/latency make difference in this benchmark of aida64 memory and winrar bench.I say that because i was addicted to overclock my hardware these last days benchmarking in winrar and aida64 memory in windows 7. So i know that, i make a fair comparison, and checked the hardware configuration, and make both benchs over same config specs: Cpu: 3.4ghz, nb: 2000mhz, memoryy: 8gb 3 sticks 1333mhz 9-9-924-33 1t. I gonna show you both win7 and win8 aida64 memory bench first. I used hdd's in AHCi mode in both hdd OS systems with AMD ahci chipset installed. win8 result: http://img843.imageshack.us/img843/4159/vozc.png win7 result: http://img35.imageshack.us/img35/2562/x8at.png Quote Link to comment Share on other sites More sharing options...
Fiery Posted October 7, 2013 Share Posted October 7, 2013 Thank you for the screen shots. It's quite surprising to see such results. But since you've stated that in other software (WinRAR) -- that happens to be latency and cache sensitive -- you can also see a drop of performance, it must be the Windows 8 kernel that does things a bit differently on your system. BTW, you mentioned you've got 3 memory modules in your system. Have you tried to install just 2 identical modules, in the favorable (primary) DIMM sockets, just to make sure there's an optimal dual-channel operation for your motherboard? I wonder what sort of performance would you get with such changes. Quote Link to comment Share on other sites More sharing options...
chumanga Posted October 7, 2013 Author Share Posted October 7, 2013 Starting, i wasted your time, sorry for that. While i make a lot of bench in differents ways like memory clocks, timmings, nb clock, cpu clock to benchmark winrar and aida64 memory somedays ago in windows 7, i tested too in dual channel 2 sticks i have 2gb same models, and i see the memory bench of aida64 got more stable values without vary so much like 3 sticks. So testing in windows 8 with only 2 sticks of 2gb that make same stable values like windows 7 make with 2x2gb. Thats a solved problem, but strange win7 can make best values with 3 sticks and windows 8 cannot.

Fiery Posted October 7, 2013 Share Posted October 7, 2013 Thank you for your feedback, I'm glad you've found the root cause of the anomalies Quote Link to comment Share on other sites More sharing options...
