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

[BeepBeep2]

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?

lol you wont lose any performance in 8x/8x dont worry.

Unless you have a highly OC/ed GTX295 or 5970 it's not gonna be a problem.

The slots are in "8x/8x" but the second slot just steals the first's bandwidth so to speak. If your RAID controller card doesnt suck up all the bandwidth you should be fine. (You would be fine anyway)

Also, 4x would bottleneck the RAID card depending on how fast/how many the drives are etc.

The raid controller should be an LSI 8404E w/ 256MB DDR2

ARRAY 1 (RAID 0)
2x Maxtor 250GB 7200rpm 16MB Cache SATAII (formatted to 320GB) with the other partition for Linux

ARRAY 2 (RAID 5)
3x Western Digtial 750GB Black 7200rpm 32MB Cache SATA II

You Should be fine..


If you press Control F1 you get More Options under the PCI-E setting..you can forcr 16x and 4x if i remeber..

If you use 8x it will force Both Slots 8x...

This Means if you Set the Second to The Raid Card for 8x your Ghraffics will be *x ..

You will not see a bottle neck with the GTX and that Raid card..You just cant Xfire now

790X UD4P DDR2 .......BIOS F9......

After running F8 for awhile i decided to try F9 again..

I Now can use Cas 7-7-7-20 timing on 1066 divder.. before in F8 it would not like to run cas7 for Higher freqencies..it would lock on boot or do other wierd stuff...Seems Giga tweaked the Ram timing in Bios a lot better.. I didnt notice this the first time i tried F9.. Im actually liking this Bios ,, a little more despite its low HTT Ceiling...

I can easily run 620 @ 7-7-7 @ 6-6-6 @ 5-5-5
where on all Previose Bioses this was very diffacult to run 590/600 on the 1066 divider using the Same Ram in all Bioses.

I also Noticed F9 uses less Volts...
F8 needed 1.56v for CPU and 1.375v nb vs F9@ 1.538v and NB 1.32v
Last week F9 was buggy..This week ill share my beer with it.

not worried about XFire, never have done SLI or Xfire because I just don't have the lump sum to pay for two cards, and when it comes down to it, when i do feel a bit behind its better to just buy a new card. Im looking into a 5850 or even a used 5870 soon since nVidia has been stupid with the renaming/rebadging and the whole GT300 thing.

I'm having trouble with voltage not being seen or being adjusted in my bios.. I set it to 1.475 and only reads 1.408. I tried bunch of diff programs all read same, also tied F8B bios same thing, that bios increases my temps 5c load and idle. Thx

[Divine_Madcat]

What power supply do you have? And for that matter, what is the rest of your gear?

I guess i would have to suspect a weaker/older PSU, especially one with split 12v rails that cannot supply the juice needed by the CPU. If it is older, then adding other newer components into the mix may make the situation worse..

PSU Calculator

Do you have anything overclocked? Which TDP of the 965 are you running? The answer is in the details.

A very barebones run of the calculator suggests your 650 should be enough. How old is your PSU? Have you had any storms lately? Is it possible your PSU might just be dieing?

Similar problem to what I've experienced. Try switching the PSU power switch to the off position for a few seconds and then back on as that is what temporarily alleviates the problem for me. I use an Antec 550HE and hadn't had this problem until I switched from 770 to 790x, all other hardware stayed the same.

[Roger20]

The psu is only about a year old maybe a year and a bit.. I have C3 125 watt version..

Well it still doesnt matter, even if the 5 drives+ card use up all 8x of allotted bandwidth the worse perf drop you will see on your GPU is 1-2%.

Heres the breakdown of a 5870 on 1x, 4x, 8x, and 16x, PCIE-2.0 bandwidth. Even the 4x runs quite well, only bottlenecking the GPU a small amount.

You should also be able to push the PCIE bus speed to around 104-106 Mhz without issue, 110+ is when HDD's start getting mad at you and corrupting.

I found something interesting with my MA790XT-UD4P. I'm running the F8b bios, and if I have my Western Digital external HD, model WD2500I032 plugged in, I can't move around the BIOS screen. A little bit of a nuisance, but obviously pretty easy to work around.

Thought I'd share.

[Daveburt714]

aythrea: Other than that glitch did you notice any improvement or new features by going to F8b?

I was thinking about flashing it, but I've kind of had my hands full this weekend..

It looked like it was just an update to support new chips, but ya never know...

[gOtVoltage]

Note:

as for Not being able to Move around in Bios ..Ive only seen this when the Ram or CPU Clocks were set too high after a flash or if you did not Clear CMOS and set defaults before Overclocking...

I use Hybrid Option on all the Bioses..To me Hybrid seems most stable Lthough in on a 790X UD4p DDR2....The 790XTA/790XT UD4p should be simalar as well.

To be honest, I didn't really look around before the flash. I loaded everything up, flashed my bios with the newest, and went from there.

I found that CTRL+ F1 on the main menu opens a menu to let you do some tweaking on your Northbridge and Southbridge, but it seems relatively inconsequential.

Just this week end I ran into a problem with not being able to move around in bios. At first I thought it was the need to enter a password to enter Bios(I have kids and they like to change thing on me, shouldn't taught tham about bios), but when I removed it, rebooted I still could due or almost due nothing in bios. Prior to this I had play around with gigabytes ET6 (newest vers.) tool. Tryed the auto tunning, of witch kicked my 7850 BE down to 1.4 instead of kicking it up from 2.8 to what ever it this chip could Handel. So I ended up uninstalling ET6. Boot up and was able to due anything I wanted to in Bios. Plus I was back at 2.8. I don't know if this the answer to any one else who is having this problem but it worked for me. Just one Question where is the F8b bios as I'm running F9, I didn't see the F8b bios on gigabyte site.

[BrokenWall]

Wish I could find out what is going on with Gigabyte, it looks like they are forcing some of us to buy new motherboards to get support for Thuban. Example the 790XT-UD4P has had bios support since 4-6-10 for Thuban but the 790X-UD4P (DDR2) board has yet to get any support for it.


After going though the list the only DDR2 Boards supported are:

GA-MA78LM-S2H -- 760G+SB710
GA-MA785GT-UD3H  -- 785G+SB710
GA-MA78LM-S2 -- 760G+SB710
GA-MA78LM-S2H -- 760G+SB710
GA-MA785GM-US2H -- 785G+SB710
GA-MA770-US3 -- 770+SB710
GA-MA770-UD3 -- 770+SB710
GA-MA770-ES3 -- 770+SB710
GA-MA74GM-S2H -- 740G+SB710
GA-MA74GM-S2 -- 740G+SB710
GA-M68M-S2P -- nForce 630a
GA-M52L-S3P -- nForce 630a

So what pisses me off the most is the CPU I am going to be buying will also require me to fork up the money for a new motherboard as well as DDR3. But its ok for me to take a new CPU and put in my wifes 630a board or my mother's $45 740G board but not my higher end 790X board.

[uncle john]

I assume Gigabyte will eventually have Thuban and Zosma supported on all qualifying boards. Has anyone contacted their tech support?

[richierich]

Be patient, hopefully Gigabyte comes through.

[p4spooky]

Be patient, hopefully Gigabyte comes through.

I hope so, I have 790x-UD4P and got the 1090T coming from Tigerdirect. Contacted support asking when they plan to support this board. No response yet

[BrokenWall]

I have hope, but if they drop support for all the higher end 790x/fx DDR2 boards then i am going to be real pissed. Specially when they already had a bios for the DDR3 board and low end DDR2 boards based on 740g at the beginning of april.

[ASharp]

Rejoice! X6 here I come!

790X-UD4P F10A is up!
http://www.gigabyte.com.tw/Support/M...S&FileID=15880

1. Update CPU AGESA 3.7.0.0

Edit: Okay, not really. Looks like they're still uploading the files heh.

[stasio]

New BIOS :
GA-MA790X-UD3P - F7a
GA-MA790X-UD4P - F10a

-Update CPU AGESA 3.7.0.0

[BrokenWall]

LMAO at the timing, I and things get done, don't you wish it was always that way.

*prays* maybe if i enough AMD will give me a 1090T, 890FX, and a 5780 for free!

[Sennebring]

New BIOS :
GA-MA790X-UD3P - F7a
GA-MA790X-UD4P - F10a

-Update CPU AGESA 3.7.0.0

Perfect timing with a new bios for my GA-MA790X-UD3P, ordered a 1055T today and when I ordered F6 where the latest bios. F7a made my day!
