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

[gOtVoltage]

Hi,

Im new here but not a total noob to overclocking. I have been a member of another forum for about a 4 months now but would like to get a different perspective from time to time.

I have a 790x-ud4p like in my sig. I was wondering has anyone encountered any form of severe ram overvoltage with this board. My problem started when I bought a set of the OCZ low volt blade 1066's. See they call for 1.8v and are covered up to 1.85evp. My board for some unknown reason when bios was set to normal for ddr2 voltage would give the ram 2.05 volts (confirmed in bios and everest). If I upped it by +.1 (which is how my board works...in +.1 increments to 2.4 volts i believe) It gave me a 1.95 volts as confirmed in bios health status menu, after which scaled properly with each +.1 increment adding an additional .1 volt to memory. After a round with both OCZ support and Gigabyte support the finger pointing began. One part told me that in no way fashion or form could the memory affect what voltage was given to the sticks, that It was 100% the motherboards fault if it overvolted. The other said that It had to be the Jedec profile either not being correct or being misread. I could not for the life of me get this memory to run at 1066 1.8 nor 1.9 volt. I tried a set of patriot viper 1066 and guess what, this memory instead was at a 1.95v for normal. I afterwards installed a old set of crucial 533 ddr2 and It was the only set that defaulted at the proper 1.85 volts. I sent the blades back to tigerdirect and exchanged them for a set of 1150mhz ocz titanium, which after trying every timing (loose and tight) available in my motherboard, would not get past one run of memtest test 5, nor even get started with prime 95 blend. This is not the only set to have issue as I have also tried corsair dominator 1066 4gb kit and results were close to same as Titaniums except they would work at less than 900mhz stable.

So In you guys opinions, is my board whack, or is this some sort of incompatibility issue with this mb and ram.
Not trying to rob a thread but thought heck this is the place with people who have similar boards as mine and someone could confirm whether it is a issue or not.

Make shure you dont use the EPP option with Auto or it will overvolt.

Set all ram options to Manual and use HTT to get your top Ram MHZ.

Jdec should set 1.8v-1.85 normally so you wont even need to add volts to it for OCZ Blades.

Also the NBvid with a 720 should have +100 or +150 or even more when running 4dimms and High NB freqency with High freqency ram.

I also use patriots @ 2.3volts @ 1200/1175 and 150mhz with out those overvolting. It could be the Bios your using.

That mobo UD4p needs the F5a Beta or newest F5 .. the F4 bios was buggy.

Ive tested with 720 and 550,, In X3/X2/X4 modes as well..


Set every thing to stock after flashing to F5(recomended) and then set Ram manually with the detected volts wich should be 1.85v,,then over the thing. i must of spelled clock wrong

Your probally on the release BIOS which is F2 or F2a...you need the F5a or F5 trust me.

Unfortunately I have returned the Low Voltage memory but I can somewhat recreate the problem and try to take pics to show what happens between the patriot memory and the crucial 533 (at least show how it changes the normal voltage with each different stick installed) Give me a few minutes to set it up and I will post ok.

Yup..Im curios because im going the Blade route too in another week or so on this Mobo. Are you on the F4 bios? Maybe Flash the F5,, the F5 had memory update fixes and CPU code.

CHEW may know about it ,, I think he has some blades but its for the UD5P not UD4P,, he still may know though.

[velozzity]

anyway Gotvoltage I have f5 bios, tried f4, both gave me 2.05 volts norm and when increased to +.1 was at 1.95, I do not use epp and the blades did not even show a epp for my board. My northbridge Vid (I assume you are talking about the cpu-nb is at +0.175 and has been for about 2 months. See I have been at a stable overclock listed in my sig but only wanted to up cpu-nb speeds into the 2300's and to do that needed to up ht to about 209 giving me 3605mhz. anything above 3605 took more vcore so it was a balancing act trying to get a faster memory speed without screwing up my stable overclock. Anyway I've been using f5 since it released about 3 weeks ago and have been a member of ocforums for about 4 months. So Im not totally new to this and have been using my computer fine just wanted more....dang the pursuit of mhz.

[velozzity]

Dont know if showing you the different auto voltages between my patriot vipers and some old crucial el-cheapo special is going to solve anything because it is'nt really relevant to my original post, guess you guys will have to trust the new guy that he knows a thing or two...or not....just kidding.
Also I have a set of titanium 1150's that wont do squat at any speed near 1150, not with 2.2 or 2.3 volts even after loosening timings all the way to something rediculous like 7-12-12-30.

I will say one thing the Blade ram rocks and it did like 1150 at stock timings, it ran fine, the only reason I knew it was overvolted is when I raised it by +.1 volt to try 1200 mhz out of curiosity I went into bios and it said 1.95. After that I reset it to normal and It defaulted to 2.05, so no voltage near 1.85 for me. I even tried to see If ryderocz would confirm whether this would kill my memory and he said he could'nt advocate running it above 1.90, so If a bios fix can fix my memory problem, I will probably buy another set of blades.

Ive noticed with my 720 the IMC would only handle about 1150mhz max when i had fourcores unlocked.

The volts for Blades could be the Bios not being able to detect the jdec that programmed for them correctly.

Also the Bios F5 when i install my patrios Jdec is 1.8v .. o i believe its Bios related to ram . I have Crucials that set Jdec just fine and volt just fine as well. There 6400's that run 1100mhz @ 2.0v and jdec is 1.8v for them too.

Also to get my Highest Freqencies i use the 800ram divider not 1066 and raise HTT.. 1066 dosnt tweak as good for some reason. This goes for my 720 and 550. The 550 handles 1200mhz but the 720 craps out with same ram above 1150mhz.

The bios just might not like the LVB's..

MY PATRIOTS RUNNING 2.2VOLTS ov TO 2.25V...

This is the F4 bios,, 720 BE with my patriots @ 1100mhz,, manually set to 2.2volts... ill check the F5 Bios now..i think i set .05 less or or one step less to make ram where i want it, come too think.




Regardless if your unlocking or not it is overvolting with my 720 and ram . Seems to Be a Bios volt issue.

Wait for Chew to chime in , he may know something about this .

[velozzity]

Well I took the pics but I dont see a way to attach them except via url. I was going to upload the pics I took. Am I doing something wrong?????

Also do you guys think this is a software e.g. bios issue that will be resolved if so I will call tigerdirect to rma this ram and tell them just send me another set of the low volts. I have a patriot viper set which do work at 1081 with tighter timings but they want do 1100 for me and I dont want to use higher voltage becuase I dont know how they respond and if life will be compromised with over 2.15v. I have patience to wait a few months to use a ram which I know is the bomb but If you think it will never work please tell. Also I told gigabyte tech to please in next bios revision give some more flexibility as to voltages and add a few negative notches -.1 to -.2 so that people with issues like me can manually tune the ram to desired voltage.

Also tried the bus overclocking but my board will not allow me to use anything above about 250 ht. Dont know what it is but I lowered nb multi and ht link multi and it still would'nt boot just a continuous loop, like the fans would rev up the down a little over and over and no screen nor post.

Also on my board and I would assume yours, the ram is increased in .1 increments. If it were in .5 I would be ok because if you remember I said normal gave me 2.05 (like it was auto) but +.1 gave me 1.95. Sucks they dont have an auto then 1.8-2.4 volt range, not auto the +.1 and so on. the First one above auto should be a manual starting point at 1.8 volts, not some +.1 over.

Well id get another set on the way from Tiger .. Im shure this will be fixed in a update.

With the next set of LVB's make shure Bios is not using the Auto EPP and dont add any volts to ram.

the LVB's will hit 1200mhz with no added volts. Your problem for them not overclocking as high is with the NBvid and 720 and that the 1066 setting is not all tweaked in the Bios yet.

Ive found the 1066 ram divder to be way buggy. When i run 800 ram divider i can clock all my dimms higher than with 1066setting.

this goes for both the 720/550 BE in X4mode and in X2/X3 mode.

I just checked the F5 Bios .. it overvolts .05v when i set it to 2.2v it reads 2.26v ,,

when i set 2.3v it reads 2.35v.....

I say its 100% Bios and im shure there will be a fix. This is the only the Second official Bios anyway,, so i know there will be more to come.

Id Just get another set LVB's on the way since you had those at 2.1volts

This way you know they didnt get hurt.
. I will be using Blades my self on this Mobo soon .

Note:
Some dividers can be buggy and the NBvid must be set to +150 or higher if you plan on using High NB with that 720.

make shure you are lowering the NB and HT the same while raising the HTT or you wont boot. HT must always be same or lower than NB to boot.

Example:

Try Clocking it in X3mode first and find out what it can do on the UD4P...This is my 720 watercooled on UD4P before i unlocked it. Note the High HTT and yes knida high Volts. The 2600mhz NB and NBvid was @ +250 to keep things stable.




Find out what the chip can do in X3mode and then try simalar settings in X4mode. My chip Maxes at 3700mhz and 2600nb in X4mode vs the Screen above....

3950mhz X3 games way better than if i clocked @ 3700mhz X4cores on it , just so you know X4 isnt always better ,, unless it performs @ the same clocks as X3 mode.

Thats where a 550 unlocks better than a 720 part comes in lol.

Besides that the Bios is in need of some Voltage updates and Memory tweaks ,, so yes get the other Ram coming and hold out for a new Bios..

[velozzity]

I must be a puss because I have only managed to get up to 1.45vcore and for some ungodly reason anything above 3600 mhz at x3 will give me a random reboot or some type of rounding error, but only after a few hours of testing. I have booted into windows before at 3850 mhz but It failed prime pretty quick. Even tried upping voltage one time to 1.475 to run 3650 but it randomly rebooted on me again. I figured It was memory issue so thats why I was searching for a better set than my patriots.
dont know why but with the patriots even If i lower them to the x4 multi and run like 800-900 cas 5 i still error out or reboot in prime at 3580 and above. With the low volts I was good up to 3605. to me thats wierd that the memory can make the cpu overclock better but I stil think i have to be either really bright but dumb at the same time because I understand the basics but cannot get my chip higher, or either I have a crappy overclocker. Also I am using x64 vista and a lot of folks said that its rare to get a chip in the 3700 and above range for a long time stable with that os??? BS or fact who knows.

Also what I was considering stable was 24+ hr prime blend/linX 150 passes 10000/linX 150 passes max memory/OCCT 24 hr. That may be extreme I know but I did'nt find a lot of the higher frequencys unstable till wayyy into testing.

Whe you say Vcore @ 1.45v you mean the CPU correct..

Well the setting for the NBvid needs to be @ +100 to +200 minimum for any 720 @ 3500mhz+ with X4core on Air or water for the IMC to not error while running variouse rams.

If you have not raised the NBvid which is set @ 1.1 -1.2v stock you must raise it to +100 = 1.3v or even +150 = 1.35v or even +200 = 1.4v..ON THIS MOBO.

Numerouse users have run +200 or higher for the NBvid to stay stable even @ 3600mhz x4 and low Nbclocks.

720's need the higher NBvid volts when using DDR2 vs DDR3 even with just two dimms x 2gigs 4gigs or 4x1gigs.

The DDR3 IMC is a lot stronger on 720 than the DDR2 IMC. This may be why the 720 isnt deemed a X4core. Because of a weak DDR2 controller who knows.. Ive also found that people have clocked them higher in AM3 Mobos and with AM3 ram better than with DDr2.

My same 720 will run 3800mhz X4 Nb @ 2600mhz DDR3.
but barely does 3700mhz with DDr2 and 2400mhz nb.

Too bad it wasnt my Mobo and DDr3 that i tested it with ,, always setting up stuff for friends dang it.

[velozzity]

Yes here a run down of my volts and settings as of now I have them memorized

cpu vcore: 1.45 or +.125 over stock
nb chipset voltage: 1.2 or +.1 over stock
nb-cpu vid: .175, which i think is around 1.35 volts this is for cpu nb at 3436 which I am testing now have ran linpack for 20 passes and now starting prime 95 blend will let run overnight.
sb chipset voltage: stock

have been at these settings for about 2.5 months now except for the cpu-nb frequency which i just upped by 1x the multi (was at 2233)
I upped it 203 mhz because of a thread I read posted by tony at ocz about the frequency being better to up than memory frequency. I thought if i never get the memory that I want to work than I will have to get the extra bandwidth somewhere, and surprisingly increased nb while leaving memory alone is about same as leaving northbridge same and increasing memory from 1080 to 1115 to 1130 mhz, about same yield in lowered latency and increased bandwidth.
My bandwidth in everest went from about 8450 at 2233 nb to 8700 at 2436 nb cpu speed. and latency dropped from 50ns to about 47.5-48ns.

[Daveburt714]

If you have not raised the NBvid which is set @ 1.1 -1.2v stock you must raise it to +100 = 1.3v or even +150 = 1.35v or even +200 = 1.4v..ON THIS MOBO.

Did anyone ever figure out exactly what is being set when CPU-NB is on "Auto"?

I get the feeling it's actually @ 1.10v. If thats the case, adding .2 is no big deal...

I really like this board (MA790XT), in fact I moved it to the main rig replacing the M3A79-T, but I hope they fix the monitoring features on the next bios release.

[artus]

hey all, just found this thread its just what ive been looking for. chew a question for you if you dont mind I noticed when you posted your bios pics your running the cpu at 1.55 is that safe for 24/7 use on air at the moment im at 3.4@1.45 with my nb at 2600 nb vid@1.4v on a MA790XT and would like to see if I could push it some more


Thanks

[mondena]

Latest bios is F5/F5a (same), update to that; I haven't had any problems and am running it with my 720BE unlocked.

sorry, i took a couple days to get back here, i didn't have any ram.

mine is the DDR3 version, where do i get the F5/F5A bios? cause Gigabyte's site only seems to have up to F4G.

[velozzity]

Well post back, If anyone has had the same problems as me with voltage not setting correctly for low volt ram like the ocz blade which needs 1.8v - 1.9v to work I have written gigabyte about 5 times, the last time telling them basically that the 790x-ud4p could go from being a very good product to an excellent product with a little refinement and they needed to open up some more memory options for better fine tuning. I described to them that how out of 5 sets of memory I have tried in this board, only 2 would do advertised timings and speed with voltage advertised, 2 would'nt work (would error out in memtest instantly) anywhere near advertised speed (1066) no matter the timings, and 1 was overvolted. They said they would forward my email to the bios engineering department for consideration hopefully that means they will look into things. I am not a world famous overclocker just someone trying to get more for my money but I explained that a even though the 790x was not the ultra high end, that alot of enthusiasts were buying this as a cost effective solution for gaming, and that enthusiasts like options to tweak, that the 790x although inexpensive compared to its brothers the 790gx and 790fx, was more of a gamers board due to lack of integrated graphics, and its bios should be treated as such, not neutered.
Hopefully they are listening.

[jamz1155]

I hope I am not alone in this -- when trying to edit the option with a name something like "AMD C1E Support" in the BIOS/CMOS, does the whole CMOS Setup Utility crash for anyone else? This option appears under the same menu as Virtualization, Cool&Quiet, etc.

This is on the AM3/DDR3 version of these boards, with the latest BIOS F4G.

Getting weird problem with UD4P (F5 bios). Overclocked my Phenom 9550 to 2.8Ghz (1.3v), prime95 stable and so on. Next step is 2.9Ghz, but when I set HTT to 264 motherboard doesn't post, it show this: "Warning! Now system is in safe mode. Please re-setting frequency in CMOS." Tried bumping all possible voltages, decreased HT/IMC multipliers, cool&quiet disabled - no effect. Even tried F4 BIOS.. Your help is very appreciated.

Did you drop the ram divisor as well? Your ram might be running out of spec and failed to post.

[Matas]

Yeh, I've dropped it as well, to x3.33.

[gOtVoltage]

Yeh, I've dropped it as well, to x3.33.

Drop your HT one setting and reboot. There is a HT ram problem when around 255 - 265htt .


Dosnt do it with my 550, but it does with my 720..why i dont know.


Even try raising the Volts for CPUvcore up another notch , sometimes the Bios will lower it with certain HT setting (buggy).


If you notice when you get the no boot , i believe the Cpuvcore Voltage is dropped/lowered in Bios too..

Try using another low CPU multi with higher HTT. Make shure NB and HT are set the same.



It can be frustrating i know.

[Matas]

Unfortunately, can't boot in any configuration I've tried. POST error still occurs or sometimes there is only blank screen, no beeping. Lowered HT/IMC from 9x to 8x/7x/6x, decreased CPU multiplier to 10x and set HTT to 275/280/285 - no success. Gave CPU additional +0.2v (from 1.25v to 1.45v).

[Matas]

More ideas?

[velozzity]

Mata, anything above 265 I believe on my board would'nt boot, did you try just doing a mix of multi overclocking with raising HTT??????

[Matas]

What do you mean multi overclocking with raising HTT?

[alk3myst]

I can't get my OCZ 3P1600LVAM4GK to run at 1600 with your settings chew*

I am at 1.4 NB/SB +.275 on the nb/vid, 1.475V CPU and my memory is running at 1.75V

I can get my NB Freq to 2400 like this running at 3500 on the CPU.
