GIGABYTE 9xx AM3+ thread

dude REV 1.1 of UD5/UD7

i see review it still has VDroop with LinX

oh i know it still has vdroop, i think the rep was alluding to the fact that the bios has the llc option.

...why on earth do i/should i ever have to do that? i am the consumer and i paid quite a few bills for this board, the company should fix these issues; not me. thats ok though, i have been talking to newegg cs; and they have agreed to give me a refund (store credit only, and -15%), i do a lot of business with the egg, so they decided it was best to take care of me.


asrock fatality here i come!

F7 bios fixed the C&Q, but I also had to set the CPU voltage in bios +.075 higher to reach the same voltage in windows as on F6. Doesn't really change anything, just an observation.

There is a bug I've had since I started with the FX6100 though. Whenever I set the frequency above 5 ghz the bios hangs when I try to exit and save changes. It is saving the changes though, and after I restart it boots fine with the new settings. Has anyone else encountered this?

Gigabyte sucks on AM3+, vdroops, crapy bios, crapy support...

I always bought gigabyte (since am2) on intel and amd platforms but for now i have enough.

vdroop has been sorted on rev1.1 a few months ago, we benched UD7 in London, was holding vcore OK while benching

ok waiting for a bios that work as F6C for stability and overclock but have new features and stable vcore as f6f

that's for ud3 fx

I just loved the asus m5a99x bios adjustments it has so much more features, but I just hate that graphic interface. Mine 990fxa-ud3 bios looks exactly like my old 790fxa-ud3p.


Asus also have much more memmory settings and for the first time I was able to run elpida hypers prime stable @ 2000Mhz 7-7-7-21 w/ 1.66v in an AMD setup. If those timmings could also be added the bios would be perfect.

We don't need load line calibration if vcore is solid and same for idle and loaded cenarios. Vrm spread spectrum and optimezed vrm control based on current demanded is also very nice, same for the over current manual adjustments. But I think those options will never be available since it hasn't got a digital vrm. Asus bios also doesn't have a working solution to disable APM, even w/ apm disabled my cpu trhotled down while fully loaded and overclocked.

Yes they do.

Anyone know what the changes are with the 1.2 revision of the UD3?

Thanks for sharing your opinions about UD3. I will try to test this board this night and see if I get the same conslusions. I have rev 1.0 btw.

That's exactly my position with my FX8120. Have gone right back to F6c since each new bios version since. v1.0 as well.

I found that memory wasn't stable until F6c and was affecting my crossfire setup. Using the same RAM as i was using with my 890GPA-UD3H i still can't get the same level of speed or timings with the 990FX-UD3 so the bios still has a way to go on that front.

I'm not even sure that the bios has control of the VRM either. When i set 1.435 for VID in the bios it is reported as that via software until i run a stress program where it rises (reported) to 1.50V. I've not measured the voltage with a DMM to see if it's the reporting that's wrong or the voltage is actually rising but something isn't right.

I think the quality and effort put into AMD boards by the manufacturers is reflecting the position the AMD CPUs have in the marketplace. As there will be less boards sold the corresponding amount of effort spent is lower than for Intel setups. We're now a long long way away from the DFI NF4 days (with the multiple board and bios revisions - was hard to keep up) and i fear they are never coming back.

[aRkangeL]

Anyone have tested the new F8a Bios for the UD7?

I have to agree with you about Gigabyte's Am3+ boards, they all suck as I had to send my 970 board back to my supplier. Damn thing hated my DDR3 1600 gaming ram, it caused stack dumps and checksum errors every single time.

Sometime this week, I'm moving to Asus' 990X motherboard.

[bobgu]

Hi Everyone,

I have been a long time member of this board but I can't remember the last time I posted this might even be my first post. After reading quite a few posts about these models of Gigabyte boards is the recommendation to avoid this board?

Reason why I ask is one of the computer shops in my area have the Gigabyte GA-990FXA-UD3 on for $120 dollars, but if there are stability issues the savings to me doesn't matter. I am also thinking about the ASUS Sabertooth 990fx will be putting an 8150 in one of these boards. Already have an i7 just want an amd machine around as well.

Take care,
Bob

i have a 990FXA-UD7 rev 1.1 it has LLC on 5 levels and they work to eliminate vdroop, you just have to set them to a level other than stock. Vdroop on AMD with GB is being treated like it is on Intel, it goes with AMD spec at stocka nd you have to change a setting to get rid of it.

LLC setting isn't under the voltage menu, its under advanced CPU settings or something.

BTW i am not Swedish.

[blossa]

Pity.

I am not swedish dude lol. too bad! or are you referring to someone else?

Anyways LLC does work well on the GB 990FXA-UD7 i have tested, there are just 5 levels of LLC to chose from

BTW a user as OCn asked for the vdroop for his UD5, 990FXA-UD5 rev 1.0 Vdroop MOd(different than UD7's point):

[Augustus]

My GA-990FXA-UD3 has just blown some VRM and taken out my 8120. It might have been the other way round but based on how hot the VRM were getting i doubt it.

I've managed to see a Crosshair V and a Sabertooth in the flesh and to be frank the power circuitry on the GA-990FXA-UD3 has puny cooling in comparison so i'm not surprised it's gone pop.

Thanks for the info the board went back up in price so it looks like it will be the Sabertooth 990fx. I have more experience with ASUS so probably the better choice for me.

[Barr3l Rid3r]

M599X seems the best all around board at this moment.


Just some notes:

Bios F6C

- High voltage raise between idle and load states, 8 cores full loaded gives me around 0,04-0,06 increment.

- CnQ not working, Selected voltage in bios is the the as idle voltage

- Vdimm is pretty accurate, if you set 1,60v you will have 1,58v in MB sensor and 1,62V Real voltage.

F6F

- Huge bios/read voltage offset, You need to set around 1,50v to have around 1,42 - 1,45v

- Accurate CPU voltage, difference between loaded and idle voltage are around 0,02-0,04v

- CnQ working

BEWARE!!

- Vdimm seems like old 790FX-ud5 and some Asus board. HUGE Offset now


It still reading lower than what you set, around 0,025v but real voltage now is much higher. it can vary from 0,04V till 0,08V and if you are using the readed voltage for base, that might sums a total of 0,1V difference.

Old 790FX ud5 had a 0,06V difference

So I've placed 1,66V, readed 1,62V and real voltage was 1,73v OMG

Despite all the bios problem and the weak VRM cooling solution (why they did it pretty instead of efficient if it get's that hot? An 790FXT-UD5P HS would be muche better than that rubish.

But don't get me wrong still a great board, with no major errors or limitations, There is no board in the marked than can match it in performance and value combination.

Yes, I talked about Blossa who used your how to do guide?

[blossa]

Yepp! I used the guide published by sin0822. Great guide and thanks! It worked perfectly.

[aRkangeL]

My UD7 get a issue last week... I have tested the 8120 all day and at night i have mounted it on the case with WC and the mobo dont get in the windows or in BIOS it stays on 75 or 89 on led debug... I hav tested with all options reser bios multiple times, test with 1075t and other rams with keyboard with other keyboards and nothing i will send it to RMA.

[Viking1962]

Taken from my UD7 manual:
Code 75: Detect and install all IDE devices: HDD, LS120,ZIP,CDROM...
Code 89: 1. Assign IRQs to PCI devices 2. Set up ACPI table at top of the memory

Check cables if you have any IDE devices. Code 89, I dont know what this means. Tested another battery?

Yeh a know i have read it... the mobo doesnt want to start at all, with any kind of hardware, or without it, I have send it last week for RMA

[stasio]

GA-990FXA-UD7 BIOS F8j is out.

[Soulman84]

using f8f bios right now, seems good...btw my ud7 rev1.0 has an enormous problem with vcore...setting 1,600v in bios becomes 1,408v in windows in full...that's a 0.2v gap!! is the only way to fix this to do the vdrop mod, or i can try something else?
