with 8.9.0.1023 and 9.6.0.1014 i have no dpc latency spikes for example when speedfan checks smart.
are there any newer "special" ones which also dont "spike" ?
otherwise with 8.9 i had strange noises when accessing many small files in a row coming from my 2 wd20ezrx drives attached to the sata 3 (6g) ports.
this sound is gone since i use 9.6 driver.
are there any known problems with 9.6.0 ?
dont blame me for using xp. i must use it cause ms is too dumb to make dwm (aero) 100% multimonitor compatible.
What about the Intel RST drivers v10.1.0.1008 or v11.2.0.1006?
Which Intel RAID ROM version is within the mainboard BIOS?
board is an intel dq67sw with raid rom 11.2.0.1527.
i tested everything official above 9.6 and they all make huge dpc latency spikes (2500us) when speedfan refreshes smart.
not every time but when speedfan just runs i get some every hour.
i have 3 drives in speedfans smart area.
1x nonraid seagate notebook hdd (systemdrive)
2x wd 2tb greens (raid 1)
to reproduce the dpc problem i switch very fast (with mouswheel up/down) between all drives in speedfans smart area.
the dpc spikes happen very quick then.
i had the same problem with an ich9r mobo which i used before.
when other tools like parkdale or gsmartcontrol access smart i get monster dpc lags like 170000us with ALL VERSIONS!
even my mouse freezes for half a second or so.
look at the pic: http://abload.de/img/170000usg1bap.jpg
luck, that speedfan isn’t doing the same.
with 9.6 i never get dpc spikes when i switch smart between the drives in speedfan.
p.s.:
the most frightening thing was the “beep” sound coming from my raid drives when i use 8.9 with drives attached to the sata iii (6g) ports.
it sounded like the heads are doing 2-8x more movement like normal, so the normal hdd “brrr” seeking sound sounded more like a “bzzz” beeping sound.
i had this extremely while doing a random qd32 with parkdale.
so i mention this besides this thread before i forget it again.
maybe it can even kill drives or reduce lifetime.
with 9.6 all sounds normal.
with 8.9 and drives attached to the sata ii (3g) ports all sounds normal too.
“9.5.4.1001” (i used this one from dell http://www.dell.com/support/home/us/en/1…?driverId=Y1W44)
it doesnt have the beep bug and no dpc latency spike till now (ran it for 10 minutes now).
i’ve also looked a bit more into the “beep bug”.
it also happens with drives connected to the sata ii 3g ports with all 8.x drivers.
for example i start reading 5 files at the same time my speed drops down to 5-10mb/s and the hdds produce this beeping sound.
could it be that ncq isnt working ?
i also must say that this time i forgot to align my raid 1 with 2x wd20ezrx (4k hdds) so maybe this is the reason ?
no matter, i think i’ve found the right driver 4 me and my xp now.
i really hate intel. the same stuff i had with the 82579lm lan driver. with that i use the totally outdated old 11.8.84.0.
intel. the biggest manufacturer of computers in the world … … lol. 
fernando: do you remember any problems with 9.5.4 (bsods, crashing raids, etc).
thank you.
No, not really.
i really thought that intels latest drivers (raid n lan) for win7 were better but they behave as bad as latest drivers 4 xp.
today i made a test with win 7 x86 and x64 on q67 chipset.
dpc got insane with latest drivers for raid and lan.
then i installed the raid:9.5.4.1001 n lan:11.8.84.0 under win 7 too and things got well again.
This is one of the first Intel RAID drivers, which belongs to the “Rapid Storage Technology”. I generally do not recommend such first versions of a brandnew development platform, because they have a lot of bugs, which have been fixed later on.
Are you sure, that it is Intel’s fault, that you get problems while running the SpeedFan tool with your system? Maybe it is the SpeedFan tool, which doesn’t work properly in combination with certain Intel devices or drivers. All software manufacturers should take care about the demands of the chipset manufacturers to guarantee an error free usage of the related chipset devices and drivers.
This may be possible. Why haven’t you corrected this mistake?
Hi!
A little bit OT, but why is Aero not multimonitor compatible?
I use 2 screens (with different size and resolution) at home on one Win10 computer without problems.
Maybe it’s your graphics cards fault?
BTW: Intel DQ67SW is crap. We use it at work and it’s a really really bad mainboard.
High DPC latency caused by the integrated Intel 82579LM NIC (during heavy network load, eg move file to/from server).
Sometimes the Intel USB 2.0 controllers don’t get initiallized properly.
This kills mouse and keyboard. We have to connect a keyboard to the NEC USB 3.0 controller and restart the Intel controllers in device manager.

intel onboard and amd hd 4670 with cs 1.6 (counter-strike, oldskool) windowed on primary monitor 1280x1024@60or75hz + dvbviewer on secondary tv 1920x1080p@50hz
on vista+ with aero (dwm.exe, uxsms) i have huge judder every couple seconds in cs 1.6 and dvbviewer.
without aero i have tearing in cs 1.6 and dvbviewer.
both run beautiful on win xp together.
i have dq67sw revision 09 and 10 and both perform good now with the new "old" drivers.
the only thing which gives me huge, very huge dpc latency with the intel nic driver mentioned above is a port scan with BluesPortScan.
but it performs better than with a cheap pcie reatltek 8111 card i used before.
on startup i had keyboard missing sometimes (bios eventlog). i set hdd delay to 5 seconds and til now keyboard is always there when booting up.
the only thing i now have is dpc latencies ~300us when i move my logitech mx 518 mouse attached to a usb 1 hub.
on my ga ep35-ds4 which i used before i didnt had such latencies on the intel onboard usb 2.0 ports.
maybe its again a driver problem (inf) ?
must try all older versions. 
but 300us is smthg i can live with. my firedtv card has ~250us when in use.
now i have iastor id9 in eventlog with 9.5.4.1001.
it happend twice on my dq67sw machine the last days (old seagate momentus hdd + 2x wd20ezrx) and today also on my fujitsu q77 mobo (samsung evo 850 ssd).
(pic i found on the net)
lpm is disabled on all machines!
release notes from intel say:
is this something to worry about ?
9.5.0.1037 is best 4 xp and win7!
no dpc latency spikes and id9 is nearly gone too (nearly means that it popped up in the first week and then never again)
It may be the “best” regarding the issue regarding dpc latency spikes, but I cannot confirm, that it is the best Intel RAID driver, especially not for Win7.
The Intel RAID driver v9.5.0.1037 was the very first, which belongs to the Rapid Storage Technology, and such first Beta driver of a new technology is never the best. Otherwise the development of newer/better Intel RST drivers would have been wasted time.
By the way: Within the past years I had a lot of different Intel RAID systems running the Intel RST driver v11.2.0.1006 and I never had any problem with dpc latency spikes.
i laugh about myself. 
they freeze my machine every couple weeks.
to reproduce it faster i found out that it often happens at win startup so i putted windows in a reboot loop and every 10-30 reboots, first desktop freezes, mouse movements still possible and then also the mouse freezes (completely still image) or very rare a paged fault bsod.
when it doesnt freeze completely it leaves "iastor id9" event entry.
now i’m forced to use v11.2.0.1006.
with them installed, nothing freezes (5 hrs of nonstop rebooting today).
but 655059 us dpc latency sometimes.
thats 655 ms, more than a half second.
good work, intel (the biggest manufacturer of personal computer in the whole world).
it must be unbelieveable hard to code software that puts data simultaneous to harddisks. 
on win7 i have the same huge dpc problems with my ssd + raid 1 setup.
EDIT: those 500000 us spikes happen when i write something and check smart at the same time. also smart checking was the reason for the freeze with the 9.5.01037 driver (speedfan was in autostart).|addpics|et3-1-dec9.jpg|/addpics|
