Title: 990fxa-ud3 rev 4 >>>> sata ports
Post by: kahasm on April 02, 2014, 01:41:36 am
according to specs I am supposed to have six sata 6 ports, which I do however, in Native IDE mode only 0-3 drives are accessible and therefore drives 4 and 5 are not even available.

The ONLY way to have all six ports open for access is to enable AHCI. This is very unacceptable. I selected this board for having six ports now I find out I can only utilize 4. I don't have any ACHI drives or applications for installing the driver for it and I have no inclination to reinstall windows just to install this driver.

This should of been posted on the specs!

The bug that has been bothering me is memory. I have ddr3 2133 ram, however I cannot enable XMP profile 1 or 2 without bios giving me an error and then I am stuck at 1.5v on the ram (its supposed to be 1.6) and the speed is reduced to 1333 and I should be able to take it to 2133 or at the very least 2000. There is no where to OC the ram to 2000+ without enabling XMP profiles.


FYI:
AMD 8350
Raidmax 850
16gb ddr3 2133
GTX 770 SC
NZXT Phantom Tower

If you google how to change to AHCI windows  you will get different choices but I put a link to the one I personally used.

Download CPU-z look at the memory profiles what does it list as timings on the XMP profiles?  At the bottom does it state 3T or 2T

 I take it to mean that there are three variations. In any case you always have all 6 SATA ports available to use.

OnChip SATA Type (SATA3 0-3 connectors)

OnChip SATA Port4/5 Type (SATA3 4-5 connectors)

You did not say what O/S you have. If you have Windows 7 then you can change your setup from IDE to AHCI without reinstalling Windows.
I changed Windows 7 Ultimate 64-bit from  IDE to AHCI after installation with no problems.

Switch to AHCI in Windows 7 (after install)

ok, the AHCi was changed and all drives seem to be recognized now however I still am stuck at 1333 ram speed.

I tried XMP profile 1, and got boot error, tried profile 2, same error. went back to disabled and did it manually, by 1st adjusting voltage to 1.6; restarted, back to same boot error; changed back to 1.5v and changed clock speed to 2133; again same boot error.

Ok, now I made some changes...
I changed timings to reflect what cpu-z shows for xmp-2134 (i am guessing this is xmp profile 1 in bio?)
I went from 9-9-9-24 33 1T  to 9-11-11-31 42 2T. upon reboot i was able to load to desktop. then i rebooted and changed voltage to 1.6; desktop appeared once again, however any changes to the frequency results in a bios error. bios still shows (auto) and this is 667; for xmp-1 it needs to be 1067.

so at this point no idea what so ever if my changes actually did anything. is my 2133 running at 2133? I am looking at cpu-z but it looks the same as the ones I posted before I made any changes.

is there a program on web i can install that shows what my ram is actually running at and not what its capable of running (like cpu-z)?

ok, no where have I seen what i did as even posted anywhere on web but...it works...

I tried all possible combos i lost count how many times I rebooted. finally gave up. then tried one more extreme possibility>>

enabled XMP profiles 1, and decreased freq to 1866; didn't touch anything else (i.e. ram voltage ) and rebooted.

the end result now shows ram at 1875.2. higher then the setting I gave of 1866 but lower than what i was working on, but in any case better than 1333.

I suspect the additional Hz is from some obscure voltage setting i cant see, cuz cpu-z doesn't report ram voltages
