Garfunkel Posted May 19, 2012 Share Posted May 19, 2012 L2 Cache Benchmark results in windows 7 " sp2" is highly different to windows 8 "Consumer Preview" Quote Link to comment Share on other sites More sharing options...
Fiery Posted May 19, 2012 Share Posted May 19, 2012 Clocks speeds are quite different everywhere. What was the actual clock speed did you have configured for your processor (BCLK, multiplier) and memory? (DRAM:BCLK ratio) Thanks, Fiery Quote Link to comment Share on other sites More sharing options...

Garfunkel Posted May 20, 2012 Author Share Posted May 20, 2012 I'm sorry it's sp1 Quote Link to comment Share on other sites More sharing options...

The last one is just a copy of first (Don't know why I only uploaded three pictures). The first is the default in the win 7 The second is from windows 7 And the third is from windows 8 Quote Link to comment Share on other sites More sharing options...
Fiery Posted May 20, 2012 Share Posted May 20, 2012 I know clocks are displayed on the pictures, but I was wondering whether the clocks were measured right or wrong? The first is the default in the win 7The second is from windows 7 What's the difference between those two runs? Quote Link to comment Share on other sites More sharing options...
Garfunkel Posted May 20, 2012 Author Share Posted May 20, 2012 What's the difference between those two runs? The second is the overclocked one in windows 7… The third is also over clocked but In windows 8 and in 13x multiplier The first is the default, I tried to overclock it and It does (it increased performance image 2) still using windows 7 Then I installed windows 8 and increase the CPU multiplier by one step (it decreased L2 Cache performance a lot) Quote Link to comment Share on other sites More sharing options...
Fiery Posted May 20, 2012 Share Posted May 20, 2012 Do you use a PCI Express video card in your system, or you utilize the integrated GPU of the nForce chipset? Quote Link to comment Share on other sites More sharing options...

Fiery Posted May 22, 2012 Share Posted May 22, 2012 Thank you. It seems something weird is going on in the Windows 8 kernel about CPU caches. The issue can be experienced on both AMD and Intel processors, so we've contacted both companies to find out what's behind this, and whether we could fix it or get around it. I'll let you know in this topic once we have an update to this matter. Quote Link to comment Share on other sites More sharing options...

It may be the Win8CP Ndis bug, alot of Consumer preview testers are seeing the NDIS driver consume alot of cpu and cause extremely high dpc latency which could be delaying the aida64 cache test.

I don't think NDIS is causing this, I'm thinking of booth CPU driver and the new WDDM. Quote Link to comment Share on other sites More sharing options...
Fiery Posted May 25, 2012 Share Posted May 25, 2012 So far we've been able ot narrow it down to the memory allocation Windows API call. Other software are also affected by this anomaly. We'll wait for the Win8 Release Preview before drawing any further conclusion. We're also waiting for AMD's and Intel's investigation to finish.

Fiery Posted May 31, 2012 Share Posted May 31, 2012 It seems Win8 Release Preview Build 8400 has fixed this issue. Quote Link to comment Share on other sites More sharing options...
Squall Leonhart Posted May 31, 2012 Share Posted May 31, 2012 coincidentally it also fixed the ndis and usbstor dpc bugs Quote Link to comment Share on other sites More sharing options...
Garfunkel Posted June 3, 2012 Author Share Posted June 3, 2012 It seems Win8 Release Preview Build 8400 has fixed this issue. Yah it is solved in Build 8400 Quote Link to comment Share on other sites More sharing options...
