AMD Chipset Drivers

[Mir96TA]

I have MB with AMD 790GX but USB to HDD performance slower then Intel G P35.
One thing I have notice MB drivers in Win7 64bit appears to be generic microsoft drivers. I have installed all the drivers from AMD Web Site including Chipset drivers; and still shows generic.
Now on other hand where Intel P35 Chipset which perform lightning faster then AMD, and it has all the drivers and it represent actuall chipset name.
I am not sure it is normal or not
Here is AMD. See actual chipset drivers say PCI Standard PCI Host bridge

Now look at it Intel's Drivers in Win7 64bit. It actuall says Intel P35 chipset drives

Am I having drivers issue ?

What are the actual numbers in your USB hdd transfer speeds?

 

[alexruiz]

Which drivers did you install? The ones named "xxx_SB_xxxx"?

I am not sure if I have understand you correctly
If you were asking about AMD Drivers
I have installed Ver 9.11

Crap like 1.5 MB-2.5 MB where on Intel I get 4.2-12.8 MB

As far as I know, the Intel chipset drivers are just .INF drivers, they dont contain any updated binaries. Which means that behind the scenes, they still just use the same MS drivers.

I am assuming that indeed it was ver 9.11
I asked which ones because in the motherboards / integrated section they have the SB driver, the aHCI, the RAID controller. The SB driver is the one.
Regardless, I think it is a hardware issue. 1.5 MB/sec is plainly wrong, MS generic or not.

Did you connect front USB headers? Why don't you disconnect them and retest?

Well I guess I can try that
I really need to run some sort of benchmark to have more definate results

USB performance is lacking on AMD chipsets compared to Intel ones.

Why ? and in also HDD cntroller ?

Well, I don't know the answer why AMD's USB is slower. I think AMD should answer that.

As for disk controllers, I think SB700/SB750 is more or less equal to ICH10R in a practical sense. I have used RAID 0/1, AHCI, and plain IDE mode without a hitch and with no noticeable performance difference on SB750. Is it as advanced as ICH10R? Nope. But I wouldn't use Matrix RAID or RAID5 on ICH10R and advise against such for others as well, so IMO they are equally good.

One thing I have absolutely no idea about is, however, how each controller handles SSDs. My experience/opinion is limited to mechanical drives.

It would be nice to back that up with at least something..... :whiste:

 

[Rifter]

USB performance is lacking on Windows systems, on my system in sig i cant get over 12MB/s when transferring to my USB external drive or flash drive in windows. In linux i always get 20-22MB/s. If you are getting 1.5MB/s it has to be a hardware problem i dont think it has anyhting to do with AMD.

I am searching for this kind of topic. atleast find a good topic about AMD. Thank you.

Here are USB key read off AMD 750 Chip set in Win7 Pro read.

Here are intel 9ICHr Chipset

Whole lot of difference isn't it ?

Yeah, AMD doesn't seem to have a chipset-only driver download, and I'm not so sure such things are included in the Catalyst builds.

Try your motherboard manufacturer's site for chipset drivers and see if that improves things.
