I suspect the native AHCI driver is getting better at NCQ support and other optimizations.
Little by little though, I've noticed less and less of a performance difference between the Standard AHCI driver and the Intel driver as time goes on. They tend to boost transfer rates on Intel chipset based laptops.
I'd use AHCI Intel Matrix drivers if you can instead of the Standard AHCI 1.0 Serial ATA Controller drivers. It was a matter of locating the (in my case) Ricoh drivers from Lenovo's site and installing the Vista drivers.Įven updating the drivers for these will most likely not affect your WEI scores overall. I had very similiar results on my Thinkpad T500 - installing the AMT drivers fixed the PCI Simple Communication Controller problem (although obviously made by Intel instead of TI) and ditto for the SmartCard/4-in-1 reader which showed up as an unknown Mass Storage Controller. Texas Instruments PCI GemCore based SmartCard controllerįound on HP nc6400, nx9420, nw9440, nc8430, nw8440
As for the PCI Simple Communications Controller, this is actually the Intel Management Engine Interface (MEI), the device that supports software running on the main processor communicating with firmware running on the Intel Management Engine. Here is the list of Intel PCI Simple Communications Controller drivers, Download & update Intel PCI Simple Communications Controller drivers from professional Intel PCI Simple Communications. I'd suggest installing the Vista drivers from the HP support website for these devices in compatibility mode as "Run as Windows Vista" and "Run as Administrator.įYI - here's the info that I found on VEN_104C (Texas Instruments): This will resolve the SMBus driver issue. If they're spitting out info continuously, they may be slowing down other connections on the mobo. It depends on how they interface with the rest of the stuff on the mobo. If you find my post helpful, please click on the "Post was helpful" option inside my post. Is there something I'm missing? Why does this problem surface on Win7 and not on Vista?Ĭan you tell use the PCI VID/PID of the unknown devices?
(If there are more than one values, copy the longest one. 3) Right-click on the hardware id and click Copy. 1) In Properties Window, click Details tab.
Also I scoured the hp.com support pages to find Vista drivers for this, but no avail. Every device has its own hardware id, so does PCI Simple Communication Controller. So I suspect that the missing driver is the former - but searching Windows Update results in nothing. So I went to invesigate in Device Manager, and found two unknown devices "Mass Storage Controller" and "PCI Simple Communications Controller". I was therefore stumped to see the Experience Index score a low 2,0 due to a slow hard disk! On Vista this same computer scores 5,2 - although that HD is a 7200 rpm drive and some what faster, 2,0 seemed extremely low. It's worked like a charm, and since I've read about Windows 7 having the same drivers as Vista, I didn't think I'd experience any problems, driver-wise. I usually run Vista Enterprise SP1 圆4 on the main hard drive. I've installed public beta (build 7000) 圆4 on my trusty old laptop, on a spare disk.
