Asus Crosshair 1 with nForce 590 SLI (MCP55)

My Asus Crosshair I with nForce 590 SLI (MCP55) southbridge, and with AMD Athlon X2 5000+ (Windsor).
It has the latest Asus supplied Award BIOS V 1207 from 2008.
Now I’ll be installing Windows 10 64 bit (hopefully), on a single Samsung EVO 850 SSD.

Does a bios update (from Asus) include the code for the nVidia Sata/raid controller? Or should I be looking to upgrade it from this site?
Should I be looking to just stay with the default Windows 10 drivers for this chipset, or will I find improved drivers here?


@SaintNick :
Welcome at Win-RAID Forum!

Probably yes, but your current and future system does neither need nor use any NVIDIA MediaShield RAID ROM module, because you will run your new SSD in IDE mode (note: only by using the Win10 in-box IDE driver you will get TRIM support within your SSD).

I am not sure about that.
This is what I recommend to do:
1. Download the related 32/64bit "Latest nForce Driverpack for Win7-10" and store the unzipped driverpack somewhere (just to have a driver alternative).
2. Do a fresh install of Win10 onto your SSD.
3. Run Windows Update and install all offered drivers.
4. Open the Device anager and look for devices with a yellow "missing driver" mark.
5. If there are any, right click onto them, choose the "Update Driver Software" > "Browse my Computer…" options and navigate to the previously stored nForce driverpack.

Thanks Fernando.
But ugh, after trying everything, and finegoogling, I must finally conclude the nVidia MCP55 chipset does not support AHCI. (MCP65 up).

Oh well, after first thinking I would just plonk in an Evo 850, and yeah ok add some (expensive!) DDR2 ram, and give my main PC a new life with Win 10, I discover a new Mobo is needed. Ugh!

Any recommendation for the best price/performance ratio non-gamer Mobo brand, ATX format? I’m not going to replace the PSU!!! But… yes the mobo, the processor, the ram, already the SSD, the screws… ;-(

Didn’t you know that?

To be on the safe side I recommend to take an Intel chipset mainboard. ASRock mainboards usually have a good price/performance ratio.

Didn’t you know that?

Nope. But to fair fair to myself, it was the last in the series that didn’t support AHCI.

And yes, Asrock is good, I have an ION330HT under the TV. But I’ve decided not to go the whole way, I’ll just use the SSD in IDE mode (leaving 20% free for lack of trimming?). That’s already a huuuuge performance gain. Plus 2GB–>4GB performance gain. Plus Win 10 performance gain. More than enough for what it deserves, I don’t use the machine that much. But I still love my Pininfarina case:

Still, I have a little plan-B: the Asus Crosshair Mobo has a second Sata controller, SIL3132, oh… never mind, also no AHCI support.. So IDE it is.

This was fun to read, here:

also a good comment, here:

And , to my surprise, with my SSD in IDE mode TRIM seems to be enabled:

fsutil behavior query DisableDeleteNotify
This gives 0. so TRIM is enabled.

The answer "0" only means, that the OS is sending TRIM commands into the direction of the SATA Controllers, but not automaticly, that TRIM is active within the SSD.
Note: Only the generic MS IDE driver named PCIIEDE.SYS is able to let TRIM pass through the nForce SATA Controller. As soon as you replace the MS IDE driver by any nForce SATA driver, you will not have any TRIM activity wthin your SSD.
