Hi guys Few days ago I upgraded from Z97 to X99,everything went smoothly and everything is working,I'm using 2X16GB DDR4 2400MHz with Xeon E5-2863 v3 My issue is mainly low IOPS,I installed latest Intel Rapid Storage etc and all drivers for my Mobo I'm using same SSD,Samsung 850 EVO and for testing I've extra SanDisk SSD,both are couple of months(2-3 months) Here are results Random read for X99 is now at 17985 Random read for Z97 has been 72661 and all results are bellow guys Read and write speeds are same or similar on all SSD,I've done tests too with Crystal Mark too and results are here SanDisk SSD Samsung 850 EVO I didn't tried those SSD on other X99 motherboards and all HDD have enabled AHCI etc and still the same,tried too to use standard MS AHCI driver and results are same or similar Please guys if someone have same or similar SSD on their X99 can you do quick tests as I want to rule out SSD or Mobo,there is no SMART error on any HDD,but what I'm looking on this seems is Mobo issue Thanks for any help Thanks in advance,Jura
Are you using 14.10 rst drivers? It could be as simple as disabling c states in bios. I'm guessing its related to power management. Change power options to high performance or stress test CPU and run bench again
Hi there I'm using 14.8.1043 C-States are disabled already there and power options are already high performance and done already all possible stress tests like CineBench or I've done several renders which tax CPU to 100% Thanks,Jura
14.10 is the latest. https://onedrive.live.com/?authkey=...Id=5014229B9E752333!40249&action=defaultclick By testing cpu i mean run a ssd benchmark and stress test at the same time. But you should have to since your power settings are fine
Hi there Done again quick benches with C-states enabled and Intel speed step enabled and my IOPS went from 17k to 64k in Random Read which is close where they are been With C-states disabled and Intel Speedstep disabled,my IOPS has been as bellow I will post results later on Thanks,Jura
I found something interesting for you.Hope is useful. X99 vs Z97 boot time and how they perform. http://www.thessdreview.com/ssd-guides/optimization-guides/complete-guide-to-speeding-up-your-pcs-boot-times/5/
Hi there Thanks for this,seems X99 have slower boot times,this I observed too on mine,first thought has been I'm running 2 SSD plus 7 normal HDD and this can cause slower boot times,but I'm not worried about the slower boot times at all there and thanks for this there Thanks,Jura Hi there I will do test later of today and post results Thanks,Jura
Here is benchmark with C-states enabled and Intel Speedstep Its not bad,but still is not quiet there Thanks,Jura
Install 14.10 software set https://mega.nz/#!xRs1TB5S!AQWd5lK7MvWDSEZSrLe0sQVd2SY_C3dqDznVhSHrAiU Under performance tab disable Link Power Management
I've already disabled Link Power there,that's for sure on my older driver set I will install later on,right now I'm on phone Thanks,Jura
Hi there Not yet there,right now I'm rendering,installed above whole 14.10 set and my IOPS went down around 4k in Random read from 61k to 57k and in Random write results are bit better When render is finished then I will do few tests later tonight and post results Hope this helps Thanks,Jura
Here is test,with C-States disabled and Speedstep enabled and results are poor in therm of IOPS Hope this helps Thanks,Jura
did you install just the drivers for or the whole package? those are low IOPS then what I even get and i using Sata II still
Hi there First time I've installed only drivers and then whole package,there is no difference although with latest 14.10 IOPS dropped a bit In BIOS I've disabled "Sata Aggressive link power management" which I think is something similar like Link Power Management in Intel RST Hope this helps Thanks,Jura
what about in power scheme is link state power mangent disabled? everytthing that power saving on my pc is disable in regards to hdd/ssd Then again I still can only use 11 series of IRST
Hi there Yes those numbers are low,much lower than on SATA II,not sure what is causing this Friend will borrow me his i7-5820k and I will test this CPU on my MB and test again IOPS,as I'm something suspecting,but I want to be sure on this Plus I want to get NVMe end of the month and test that too.. If you are still on X58 then I would have look on X5650 or X5670,those are great CPU and with them you should easily OC up to 4.0GHz and temps will be lot lower than i7 Hope this helps Thanks,Jura Yes there,in Power options this Link Power Managment is disabled and is it disabled in BIOS IRST 11 I've used too on my X58 without the single issue,I think on Win RAID forum there newer IRST,but if those RST works for you then I wouldn't upgrade Thanks,Jura
Got to bios cpu power settings and find Intel Dynamic Storage accelerator (TinyLake), should be there where you enable c-states.. Now in iRST enable it as well and see if it helps some more.
