MA790X / MA790XT-UD4P 790X bugs fixes etc etc.....

guys just set the voltage........Apparenlty it appears the CPU_NB vid is working.....however not detecting voltage correctly.....

Something seems really fishy about that statement to me chew*.

I'm not basing this on what voltage monitoring software says, I'm basing it on the way the system reacts. And it acts like the IMCv's are too low, plus the fact that when you change it in Windows all the monitoring software shows the changes so I don't think it's a detection problem.

I don't have time right now, but when I get home from work I'll try to run some tests that demonstrate what I'm talking about.

Looks like GBT may be up to they're old tricks of just denying a problem.

Well dave they told me same thing I told you...... Probe to verify......according to them voltage is correct.

I don't have a board so I can't do it.

I dont have a volt monitor, that i could use, but where on the mobo would you take the reading from to confirm?

Also if the nb volts are working... I would also tend to agree with dave burt as to what i ve seen, i ve been rock solid up to 3.5ghz, 3 core/4cores doesnt matter, but anything above, i start to get page fault in non paged area bsods.. i have my nb at 2200mhz, I do have 8gb of valueish mushkin ram, but timings are loose, and not oc'd, If it were other bsod's it would make sense , my stability doesnt seem to fluctuate on nb vid.. with I have in bios at +.200v so an effective 1.4 amds safe max.. I ll play again systematically this weekend maybe and see what i can come up with, could be my nb is taxed at 2200?

Its not maxed,, I have Done 2400 and My NB does 2800+ @ 1.45vid on two other Mobos.

On THIS MOBO even with +.200,,,250,,.300 = 1.5vid it wont do crap on the NB .. i dont know hwer to look but there is something going on . It may be volts or even Ram related ..

Im still playing around with the Nbvid to see if i can see Temp fluctuations when i raise and lower it. So far i it dosnt matter what i do it seems to stay the Same.

This Same 720 can do 3700cpu/NB2800+ @ 1.55vid with no erors/bsod's on the M3A79_T

I know the M3A VId works 100%. You can see it in the Nb Speed at any speed.

Somethings happening to keep the NB @ 2400 and lower.

Ok guys, as promised I did some tests tonight and here are the results.

Conditions: I uninstalled PhenomMSR Tweaker before the test to avoid any potential interference. I was going to continue the tests with just lowered CPU and Memory settings (to take everything else out of the equation). Unfortunately, with my NB Multi @ 12x (setting used with PMSRT) I got to the Win7 password screen, entered password and the machine failed to load windows... So I used the HTmulti to tweak as close as I could and still be bootable.

Heres the bios settings:
As you can see IMCv's are set to 1.30v

CLICKABLE:


After boot, all I did was open Everest, AMD Power Monitor and 2 CPU-z Screens. Both Everest and AMDPM show NBvid @ 1.20v...
Then I ran a 10 pass IBT run. The result was an "Unstable system warning", IBT failed!

CLICKABLE:


Without making any other changes, I opened AOD and added .05v to the IMC making sure that all other settings and voltages remained the same, then closed AOD. All this was done without any other changes being made and without a reboot. I then ran another 10 pass IBT run.

CLICKABLE:



Now, both Everest and AMDPM show the IMC at 1.25v and the IBT run passes succesfully. Maybe I'm crazy, but I don't know how else to explain this other than the fact that the monitoring software is working correctly and the bios is NOT setting the CPU-NB vid...

chew*: I may be able to borrow a DMM from a freind and it seems like the UD5P and UD4P are at least physically similar, could you shoot me a pic of the NBvid measurment points on the UD5P?
At least it would give me a starting point of where to look....

Sure after my PSU' s arrive tomorrow and I hook everything up to boot it.

Thanks Bro...

I finally got a reply from their online tech support. I don't know if its a language barrier or what, but it's as bad as I remembered with the DS5 and S2H....
Asking me the same questions I had explained in the previous message...

This really is a MUCH better board than either of those, and I can work around the problem to some extent by using Phenom MSR Tweaker but this is a pretty serious problem.
I hope they don't just give up on it...

Hopefully the "powers that be" are watching this thread and can explain the results I got in the previous message...
