Gigabyte GA-MA790FXT-UD5P Thread

[stasio]

You are the one, we just love you man!

I will give it a try right now.

It seems to fix a lot of the problems I was having, but I dont understand german very well.

Bugs:
-------------------------

CPU Clock Ratio:
can be set to x16.5(Core Boost Performance multi) even when the multi on the 1055T is locked at a maximum of 14.
when set to 16.5 it will be ignored and silently set to 14 without reseting the value in bios. maximum should be x14.

NB multiplier:
randomly changes to x10 when manually set to a x7 or x8.
x6 and x9 work fine.

ACC:
only 4 cores can be adjusted /are displayed

Core Performance Boost (CPB):
- when disabled the default Vcore is set to 1.350v
- when enabled the default Vcore is set to 1.475v

this can lead to some confusion when the Vcore is changed manually and the Core performance boost is then disabled or enabled.
maybe this can be seperated as well like the CPU multi?
example:


RAM:
Refresh Cycle Time: when set manually the value is set to a higher one, 90ns->110ns; 110ns->300ns; 160ns->300ns;

RAM:
here starts the real fun when trying to set anything manually....
my ram is rated 1600mz@1.65v@7-7-7-24-2T, it passes memtest+ 4.0 without errors,
but the OS crashes almost immediately and i had to reduce the frequency to 800mhz
and raised the Vdimm to 1.7v and the CR to 1T to get it anywhere near stable.
loser timings will make the ram even more unstable so it seams it behaves exactly like its not supposed to...
also i did some test to get higher freq stable but i would need insanely high voltage on the ram (like 1.85-1.9v)
to reach 1333mhz and even than it produces erros when tested in the OS (windows7 64bit, xubuntu 10.04 64bit)....


-------------------------
Fixed/Improved:
-------------------------

CPU core control:
all cores available

Cool&Quiet / Core Performance Boost(CPB):
- C&Q "enabled" / CPB "disabled" --> fixed
- C&Q "disabled" / CPB "disabled" --> fixed
- C&Q "disabled" / CPB "enabled" --> fixed

Vcore:
seems to be very stable now when CPB is enabled, used to jump araound all the time before.

RAM:
exact ram frequency is now shown when booting and not the value thats calculated from FSBxRam multi.

RAM multiplier:
randomly increases to x5.33 when manually set to x4. this seems to be fixed as well,
i could not reproduce it, but it might occure again since it was very random and hard to reproduce.

Ok, but now I've seen that he's talking about the problems in F8H..

There is nothing about the F8j or F8k in that page...


tested the F8k and the stuck w/ CnQ always on is gone, but still impossible to use higher then 14x multi and elpida OC is bad in 6.66x memory divider (1600mhz divider I think)

BIOS F8k his review:
http://forums.tweaktown.com/f69/giga...tml#post362625

[wez]

Didn't have time to really test it out fully. But both f8j and f8k gave me stability problems with previously stable settings used with f8h. However, room ambient was close to 30C when i tried them, so there is a good chance it was due to heat. Needs more testing.
C&Q and CPB enable/disable works as it should in f8k (was still bugged in f8j)

[Barr3l Rid3r]

f8k is doing fine, but F8H still the best for every day use and better stability. F8K fixes some glitches

I can't say a word about this board, very nice indeed.

310 HTT, 2000Mhz DDR3, 3100Mhz NB speed , she can handle them all..

i never got past 1700ddr3 2800nb.. what kind of cooling?

[Tomasis]

have tested f8k, it could boot (not in windows 7, but only bios) at htt335

f8k = htt335
f5c =htt307 (stock which i got with the mobo)
f3l =htt290

true 120, now linx at 4.0/2.95/1700 c6-6-6-21 1.65v memory support and oc sux anyway

GA-MA790FXT-UD5P - F8L BIOS and BIOS bug report

GA-MA790FXT-UD5P - F8L BIOS and BIOS bug report

Tried, still preaty weak for DDR overclocking, cant pass 1700MHz rock stable even at 7-7-7-24, 6x ram divider is worst than ever now, but I'm at 8x that works fine

HT limited at 320mhz

Cnq Bugged as hell, you can disable it now, but you cant get it to work using
custom NB/CPU multipliers.

F7 did work fine w/ CnQ and manual overclock. at 955, 1055 and 1090T.

[Final8ty]

Any info on when & official new bios will be out ?

[ChanceCoats123]

So you can go well over 1666 on this board eh? I haven't tried now with my Team Group Dark set, but when I put my 720 +UD5P under DIce, I'll see how well they clock and see what this board can really do. It's done me well so far on air with my 720.

[sprach]

Has anyone tried and can anyone confirm that SLI runs on this mobo using the SLI patch developed by http://xdevs.com/e107_plugins/conten...php?content.30 ?
Here's the link to the thread and all related discussions http://forums.techpowerup.com/showth...60844&page=163

The reason I'm asking is that I'm hesitating to upgrade to a second GTX 470 and later find out it doesn't work in SLI even with the SLI patch.

Thanks in advance for your feedback.

[Barr3l Rid3r]

It looks like the support for this mobo is gone forever.


That's why my next board will be an Asus.

We need Bios Updates! memory support is so awful in this board.

For whatever reason I cannot get the @BIOS to flash the latest F8L bios???

I download from GB server. Put on desktop and unpack. Tell utility to load from file and it does not like the file.
Tried the .exe and it has a compability issue. I am running Win7 Ultimate.

I tried putting on thumb drive and using Q flash and it 'looked' like it did something but I am still on F2 based on CPUz and @BIOS.

I am sure a very rookie mistake here, but what am I doing wrong?

If you load bios defaults before flashing, same result?

Yes did that too.

So I went back to GB website and as an idiot I downloaded the wrong BIOS. I have FXTA board

Sad I know

it makes sense now

[zirnis]

just got this mobo, bios is f8k. It has problems with memory, With cruicial ballistix 1600Mhz 8-8-8-24 2T 1,65V, when memory multiplier is x8, prime 95 stops after few second's, it also stops with 9-9-9-27 2T timings and 1,65V, even 1,7V doesn't help. But it works fine with 1333Mhz and 7-7-7-21 T2 timings.

I have Phenom II 925 C2, I read number of pages in this topic, but didn't managed to find anyone overclocking 925/945 with locked multiplier. Yesterday i tried 1,47-1,52V NB with FSB 260-275 NB 1,28V, HT and NB x8 multiplier, memory multiplier x6,66 and high memory timings, but PC freezes at 40-50 minute of prime 95 runing.


BTW this is my friend OC result with this board with 905E

[Tomasis]

zirnis, test another bios rev. i dont think f8k is the best.

[zirnis]

Tomasis, which bios revision is best?

here is voltage settings. What else I should increase?
http://www.part.lt/img/1e6581b1f2607...1bfccc5347.JPG

with these voltages Phenom II 925 C2 manged to reach 270FSB @3.780Ghz NB and HT multiplier's 7 and 8 worked stable for more than hour with prime 95, but with 272FSB PC it crashes after few seconds with prime 95 running.

sorry for late response.. what is best rev is hard to tell. you have try different rev. last 5 ones. f3L was popular,, I liked f5c which was included in shipped mobo as I got. F8c seems good for some.

now it came new f8m

you have to test .. check if it is htt issue, or mem? Im not sure about your mem IC. test mem dividers too. cool your nb properly
