Hi,
Gigabyte Z68ap-d3 with 480GB SSD.
It had been set up to have 64GB as cache, by using another bootable pc to set up the space. The rest of it which windows sees, has a system and games partition.
It’s been working great as caching, with diskmark showing speed at run 2 and above.
However, since the windows 10 10586 update, the caching is dead in the water. Disk mark and other apps show no improvements! Bios for RST shows accelerated!
I detached and reattached the acceleration, no change. However, I notice that in the past it would take a minute or so to complete doing its work (HDD light on) when removing or doing acceleration. Now it gets done in 5-10 seconds!
Also, if I don’t do a clean shutdown, I get the typical repairing cache index prompt. But in windows, still no acceleration. So the bios /fw sees it but the software/driver doesn’t!?!
I tried many different versions of the firmware- both legacy bios AND uefi. Now I am using the latest 14.7 which works fine with trim in raid 0, surprisingly on the z68.
v12.9, 13’s, and now v14 latest bios and uefi from here.
I also tried many versions of the drivers, focusing on the v13 series. Now I have the latest posted. No problems as you had with the latest driver. Works fine, just the stupid acceleration is not working!!?!
I really dislike intel, there’s no documentation or logs on what it is actually doing. I remember when I first was trying to use cache + normal partitions I had to run through hoops to get it to work!
If I decide to remove the caching, can I use the option “reset to available” in the RST software and not lose my normal partitions? I will probably be moving to a software caching solution/
I have a similar issue with my SSD performance after the 1511 (Threshold 2) update… I’m on a single SSD… BUT after the update Windows “Migrated” the IRST drivers somehow messing everything up!!! I was running IRST v13.2.5.1012 before the update and after the update I found the I had v13.2.4.1000 installed… Either way… I noticed that ALL benchmarks were showing a significant drop in rates concerning 4K tests… CDM and Anvil both give me drops in 4K tests and now are very inconsistent with each run… When before any test I ran would be very accurate with only a few MB +/-… But now I get drops of up to 100MBps-200MBps very frequently… For example CDM 4K test would give me about 31-33MBps Read and 104-110MBps Write before the update… Now after the update I’m lucky if I get 30MBps/92MBps!!! I have tried different IRST versions within v13.x with all showing the same problems… Even WinSAT Disk gives me lower scores compared to pre-update… The only thing that I do notice is that Win 10 boots a lot faster 90% of the time than before…
Hmm, thanks for the reply- more info to figure this out.
My only guess is that some file system filter driver that win 10 uses had broke the way the IRST drivers see caching etc.
Why I would say this? I had used a program called PrimoCache a while back in testing.
The intel SSD caching wasn’t working. It only worked once I removed the cache from the accelerated drive and rebooted.
This time around I am not using that software, yet similar issue!
The irony is that primocache can do L2 (ssd) caching and I am looking to do this if intel doesn’t fix the issue.
Oh and I have fast start and hibernation disabled, which has been known to cause problems sometimes.
I have been poking around a lot into Win 10 and how it affects caching… I think I have a possible cause that might explain quite a few of these issues related to IRST and so on… At first I didn’t think that it had anything to do with IRST Caching but now i believe that it does… U see since Win 10 uses a new type of Compression… It sort of acts like its own cache… In Task Manager its PID 4 “System and Compressed Memory” This is how Win 10 saves RAM and keeps a low footprint as well… So after running a bunch of benchmarks with different scenarios in my case whenever Win 10 was caching the compressed memory lets say 40-50 MB+ benchmarks would end up a lot lower than when when run when idle and when Win 10 Compressed Memory was at >1.0 MB ok… So I believe thats whats causing a lot of issues with IRST… I’m pretty sure that there’s more to this issue and I think it has to do with how Win 10 handles Turbo Boost on 4th thru 6th Gen Core i/m CPU’s or ULV processors… Especially after the November 1511 Update (Threshold 2)…
IRST is the abbreviation of Intel’s Rapid Storage Technology, but do you mean the related RST driver, the RST software or both of them?
