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

[ASharp]

Doesn't seem like there is one for the UD4 at the moment.

[villa1n]

Beta BIOS F9A for the 790X-UD4P and F7B for the 790XT-UD4P have been posted on the Gigabyte site.

Seems that it adds a "CPU Core Control" option. I'm assuming this means you can now choose which cores you want to use on your multi-core chip similar to the ASUS boards. I'm not sure though as I haven't checked myself yet. Just thought I'd let you guys know.

Let us know if you dive in ^^

[Daveburt714]

I'm testing F7B on the 790XT right now to see if it offers any improvement with the C3's....

So far I haven't noticed any difference other than the fact that it allows you to select cores when unlocking (in case one is weak).

re; F7b for 'XT boards

Thanks Asharp...i wasn't visiting faithfully...i did spend (or waste?) considerable time researching downcoring just to discover the bios would override unlockers anyways. anywhooo....

The new core selection feature pops up on the EC/ACC page (after a system reset if transitioning from locked to unlocked) - Geez, there's two mis-spelled words included as well (let's hope the coding wasn't as rushed). That under-performing core_2 of mine can be cut from the team now I am still surprised this issue alone inspired F7b. IMO they should just implement a downcoring option for all - independent from EC/ACC. Efforts appreciated just the same.

Final non-beta BIOS files are up for the UD4P boards.

F9 for 790X-UD4P
F7 for 790XT-UD4P

Changes:
1. Add CPU Core Control option
2. update Raid\AHCI ROM

Anyone that has tried either of the two please report RAID ROM version.

Thanx


EDIT : Nevermind, found it > F9 seems to have upgraded to 3.0.1540.59, when F8 and older is 3.0.1540.47

[Lokinhow]

I can't get Prime95 stable with more than 3.5GHz here, I need 1.475v to stay at this frequency. I think I have a bad chip
I'm using the F5 bios, is it worth to upgrade to F9? or it probably will not help?

specs on sig.

FWIW, I would try the newest BIOS.

My 940 really liked V's, 1.475 may not be enough. It was much more sensitive to temps and didn't get flakey until it got over 53c...

I take no responsibility, but if you keep Load Temps under 53c you can probably give it a little more juice. IIRC, my 940 was good to around 3.8 @ 1.55v under water...

Watch Temps, take your time and play with it...
Pretty sure you have a little more headroom if your willing to push a little.

hmm I'll get better fans for the hyper212, it's getting at 61ºC after some time in Prime95, the ambient temperature is not helping too

I'm gonna to play more with that, thanks for answering

edit:
does the ACC makes any difference on Phenom II's ocing?

Use F8 NOT F9

Ive tested all Official and Most Beta's from F1A to F9A for 790X UD4P .
The Highest and Most stable unlocking and clocking Bioses are as follows
( F7 and F8...ATM)

After trying the F9 Beta and F9 release ,, THE 790X ud4P would randomly drop Hybrid and and or Auto ACC...It would not stay in X B50 mode in any of the F9's After a soft reboot or when changing CPUx freqencies.

F8 works for Hybrid and or Normal Mode
Reboots normal
Cold boots Normal
Overclock settings are fine....They do not reset..They stay right where you put them.

F8 shows the Voltage you set next to the voltage settings .The F7 does too. Any Bios Lower than F7 will be missing those voltage read outs next to the Item that you would adjust +/- volt wise.

My favorite ATM is F8 over my previose F7 which was also 100%stable.

I guesse that covers it.
I dont know about the raid , Im NOT running it on this machine but AHCI and Multiple drives and DVD(AHCI) run flawless for me .

Note: Core changing worked when it decided to keep my chip unlocked..The new Core option and or ACC would just reset when kept on Auto for the Cores to enable.

Thats why i went back to F8 ..No problems Unlocked above 4100+ on me little 550.

Having soft boots if I try to set HTT >264. It happens with all BIOS versions, tried a lot of various BIOS setting configurations, but I can't make my 790X-UD4P and X4 9550 to work at >2.9GHz

[haraakiri]

I have got 790XT UD4P with phenom 2 550. I got a strange problem.
When I start my system, sometimes, it turns on for 1-2 seconds and turns off. I cant turn it on now. The only way to turn it on would be to unplug power cord, wait a few seconds and then turn on. Strange thing it happens only once in 2-3 days, not always.
I changed psu, cabby and cmos battery too, to no avail. Still the problem persists.
No overclocking running at stock. What could be the problem?

[synth]

I agree with gOtVoltage, I've been using F9 since i got the 790X-ud4p and was having problems with ACC disabling itself and a few other weird issues here ad there, I "upgraded" to F8 and all problems are gone, infact I'll need to look at my notes but i'm pretty sure its clocking slightly high now aswell.

Cheers,

[BeepBeep2]

Darn, I know F8 is more stable than F9 as a BIOS...but F9 has a later RAID ROM...

But my overclock seems significantly lower than it could be also. Darn. Should I flash to F8 and hope my RAID 0 array is okay, or stay with the F9 I'm already on?

It seems to be a known issue and it gets worse when you get to 269-270 HTT. Your BIOS becomes corrupt and RAM voltages are set to 2.8v+.

[ReverendMaynard]

Would the 790XTA-UD4 fall into this threads purpose? Same board except SATA3 and USB 3...which I have disabled

Has some really stupid bugs that makes it difficult to work with on DICE/LN2. Anything over 240 HT and it drops the cpu multi to default. Anything over 1.825v core causes a grey screen/freeze.

I'm wondering why all of these boards have an HTT limit in only the 200's...some CPU's and boards can boot into the 400's.

[uncle john]

My HTT is at 281 24/7 and will easily go over 300 but I'm using G2 Brisbane not Phenom.

I'm using the XT version of your board Beep and the HTRef will go alot higher if your willing to push it...

BE WARNED THOUGH! Pushing the HTRef above 250 can cause some serious OS problems and do all kinds of funky things to your Rig!

Don't try it on your good system drive until you've tested things...

That being said, I got 311 HTRef on my board and it was pretty stable.



The trick seems to be to give your Chipset-NB a little move volts. 1.3v should be enough BTW...

Check out this thread:
http://www.xtremesystems.org/forums/...238910&page=11

Start @ Pg 11, message #273 and go on from there...

Personally, I was really suprised how much I could get out of the HTRef once I tried pushing it...

[uncle john]

Yep, 1.3V nb chipsette for me too.

This BIOS has a mind of it's own. I've got cpu voltage set at 1.025v for my eco-clock and cpuz is reading 1.2v. It was reading correctly the other day.

[trt740]

I just bought this board is there away to lower the ram voltage all I see is a away to up the voltage past normal, but I cannot find away to lower it. My ram can run at ddr3 1600 at 1.5v but the default appears to be 1.6v

[Daveburt714]

trt740: Short answer is NO....

The XT-UD4P is a strong OC'ing board, but it's one major drawback is it's ability to adjust voltages with any detail.

Not only when it comes to RAM, but also, IMC, CPU, Chipsets and pretty much any other voltage you would like to fine tune.

Don't get me wrong, it's probably one of the better AM3/DDR3 boards out there, but the coarse voltage adjustments are pretty annoying...

Not only that...
You can use AOD to fine tune the voltages (which helps), but don't expect software monitors to report it correctly (especially the IMC v's)...

It's a fine board, and I really like it, but the lack of detail on voltages, and the reporting errors do make it a little harder to deal with.

If you keep playing with it you'll get strong clocks, it's just not the most user friendly board...

thx thought I missed something

[dA_PhReAk]

Can anyone confirm if the MA790XT-UD4P with F7 can unlock a x2 555 to x4? (cant do it with a lower bios version right?)

[haraakiri]

You can do it with F7. I am currently with F7 and 550BE unlocked.

[BrokenWall]

I have a question, I'm a bit confused about the PCI-E 16x slots on this motherboard.

So it says the first one is 16x which is what my 9800GTX is in, and the manual says the second one is 8x and when you do crossfire it is 8x/8x.

If I buy a raid controller which is 8x, will it run at 16x/8x or will it drop to 8x/8x since, if so is there a way to force maybe 16x/4x?
