Hello. I recently got an Asus P5NE SLI for free, and have set it up with two gigs of DDR2, a Samsung 830 SSD, and Windows 10. Using Crystaldisk Mark, the measured drive speed using the onboard SATA ports is remarkably slow. It consistently tests around 130 MB/s. Other older motherboards I’ve used this Samsung drive on generally test at about 230 to 250 MB/s, including a couple with GeForce 6150SE/ nForce 430 chipset. Maybe this is the best this chipset and motherboard can do? My slow as snot Asmedia 106X PCIe 1X SATA card tests at 200 MB/s in this board. I’d appreciate any tips that might be had for increasing the speed of the SATA ports, or confirmation that this is as good as they get.
Are you in RAID mode? This chipset only supports IDE Or RAID, so to get AHCI like speeds you need to be in single disk RAID mode. That may require a clean install, or registry edits which I only know for Intel systems, clean install may be quickest solution for this.
Is the partition you are testing aligned? Maybe your drive doesn’t deal with compressed data very well, try zero fill test (File, test data, 0X00 zero fill).
Does your drive show up as being in SATAII mode in CrystalDiskInfo? Some of these old NF4 chipsets needed a hard mod before SATAII is possible

If you remove your heatsink to look, and do not see the little black label saying Ultra or SLI, and the resistor layout does not look similar to that image, then you have the vanilla NF4 chip where SATAII is not possible.
I see similar reports here, SATAI speeds only, see pages 959-960

Thanks for the good search skills. Those posts confirm that the speeds I’m seeing are pretty typical for this board/chipset. So there’s no fix for the board itself, for faster speeds a PCIe controller better than the one I have is needed.
Yes, PCIE controller will be a lot better, unless you want to see about doing the hard mod on your chipset (you can do solder blob, heavy pencil, or conductive paint, it doesn’t have to be a resistor soldered in there)
