Aspire 5920G Never allow me to enable HDD write cache

My New Aspire 5920G never allow me to Enable HDD write cache setting.If i uninstall the AHCi driver it allow me to Enable the write cache.
Is this a driver bug or Vista problem

 

same problem i had too, after installing ROBSON's driver i lost write cache,
now in XP, after installing Intel Matrix Storage driver 7.5 i can't enable too

 

Well it seem everyone has the same problem. It could be vista driver still not yet allow to enable cache.

 

Have to wait until Intel fix it on future release...I thought 5920G Bios update fix it

 

haha let wait and see maybe Vista problem?
Wait for service pack or intel drivers.

 

I saw a new Robson drivers on Intel website
Intel® Turbo Memory driver 1.1.0.1010 http://downloadcenter.intel.com/Det...4&OSFullName=Windows%20Vista* 32&lang=eng
I installed it but the problem have not been solved.

 

hey guys !! im getting very frustrated with this problem cuz i cant achieve a write speed of even 20mb !! from an external usb2 HD !??
does this seem right to u ?
it even dropped to 4mb !
do u guys think that i have some kind of problem with my harddisk or its just write caching screwing things up plus my disk status LED never seems to take a rest ...

 

Try going to the intel manager and enable the write back cache...

It's the same for intel raid - you have to open the matrix storage manager, go to advanced mode and rclick your array (probably hdd in this case).

 

I have the Dell Inspiron 1420 and I have this problem too <_<

Just wanted to note that, so you guys know it's either a Vista or Intel problem

 

No one knows just wait and see.

 

I just checked... My write cache option in my 5920G is working just fine.

 

Lucky You!.Can you post your AHCI Driver version?
Go Devise Manager> IDE/ATAPI Controller >Intel AHCI & select proparties

 

Here you go;

 

are you sure its working?

i can enable mine, but when i go back its off again

 

>i can enable mine, but when i go back its off again

Yep, just noticed that... Same here. After i selected it, i went back into it and it was off again. Oh well... So much for that one. Maybe HP will have a firmware fix for it like they one they have for the HD-DVD!!

 

Firmware update won't work.I'm sure this is Intel driver bug.

 

I saw in microsoft support site that windows 2000 and XP had some performance issue regarding write cache and later they had released an update. So this also may be from the OS part.

Does enabling write cache increases perfomance a lot in a laptop?

 

Not so much increase in performance,but it's increase HDD write speed bit

 

i can enable mine but i do clean install vista home premium. after you install vista enable it before you install any driver. and don't install intel matrix manager. hope this will help.

 

So it mean you're in SATA IDE Mode instead of NATIVE SATA AHCI Mode.

 

Well he must be in SATA IDE Mode, that's why he did't install intel matrix manage. It's the only way to enable write cache. Yo can also change this option in BIOS but Intel Turbo memory will stop working.

 

no im in AHCI mode. before i cannot enable it also. but now it working just fine now. i dont install ITM coz when i install it i cannot enable it again. i borrow vista home premium cd oem from my friend. that i use to install vista again.

 

>Yo can also change this option in BIOS but Intel Turbo memory will stop working.

hi.. my Best Buy 5920G doesn't have the Intel Turbo memory, and i can't add it because the connector is not on the board. So... I'd be in a good position to use the write cache.. Exactly what/where has to be changed in the BIOS to enable it.. And will having write cache on have an effect on the Vista Rating or benckmarking? Thanks..

 

Just change Sata Mde from AHIC to IDE and try to uninstall Intel matrix drivers, and restart laptop. If You don't have AHIC driver installed in Your Hardware manager it means that You can enable Write cache. I do it once and it worked for me but I use ITM and I must have AHIC in bios enabled.

 

mine dont have turbo memory also. i just install it in AHCI mode. then enable it after install vista. dont install any driver first. i dont know about benchmarking but i notice i little bit faster than before. vista rating is the same dunno in benchmarking i never try it before and after.

 

IDE mode allow me to enable write cache too.AHCI have problem.I try latest Intel AHCI Driver but problem not solved.

 

Have little performance effect

 

im only using stock AHCI driver came from acer. its working great now.

 

stock driver have performance issue

Enhance SATA disk performance

 

I reformated like 5 times to try ad resolve this issue. All i can confirm is that i not related to the robson drivers as far as i see. After fresh install i checked the option and it was still unavailable (

 

I have a T61 which has turbo memory. Vista 64, latest lenovo drivers. I am able to enable write caching.

I have not enabled "advanced performance" though which is the one that is sensitive to power loss.
