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

[BrokenWall]

Well F10a works for me, no performance increases that I can see, they did fix the spelling error in the BIOS for the Manual Unlocking. Still unable to restart my computer from Windows or a Boot CD causes me to loose the Unlock. So that has not been fixed.

I wonder what the performance cost will be for running a Thuban with DDR2. Another question is , if the IMC of thuban is also better that deneb C3 in ddr2 handling/oc'ing.

I doubt it, I was able to hit 1235 CAS 5 and 1070 CAS 4 on the 790X-UD4P board...I dont think that Thuban will be much help and it's probably ram dependent.

Just updated my 790XT-UD4P bios to the F8C.
It seems to have dropped my overall temps a bit. I'll have to watch closely for a little while, but my no/low load temp is about 35C @stock setting.

[richierich]

With the latest BIOS it seems that I have a lot more issues on cold boots now....grrrrrrrrrrrrr

I saw this same issue with the 1055T @ 3.7 I just built. It could prime/OCCT/3DMark/Furmark stable all day long, but shut it down for 10min and it would go into a POST loop/recover from "failed overclock settings". 3.4+turbo worked out a better combo on this particular machine.

How often/what are the nature of your cold boot issues? Resolved by hitting restart a time/few times?

[richierich]

Dunno, can't figure it out. Sometimes I just hit the main switch on the PSU, keep it off for a few seconds, and turn back on. But it's not 100% guaranteed. So annoying.

[BrokenWall]

Lately I have had a few BIOS Issues with my 790X-UD4P

1) can't restart or ACC fails (have to turn off then turn on to keep ACC settings)
2) sometimes after a hard shutdown and try to turn on the computer the BIOS will crash and revert to F4 then I have to reload F9 and reset everything
3) ACPI issues with Windows 7 on anything pre-F9 bios

Yes it is,, can be verry very buggy...I use F9 on the 555 for UD4P with DDR2@1200,,5-5-5-24 -2T... Keep HT below 2600 and try different HT multipliers..Some work better than others and Some will cause problems such as Not booting or going into bios after a reboot.

I flashed my F9 probally 10 times or so now from F4/F2 when i was playing around..

Ive found that the HT multi's are very buggy...Depending on what your HTT is set to , it can be misleading. Youd think that 11x would be stable @2400ht..it wasnt for me but if i bumpered it up to 12x 2600mhz HT at the same clocks my buggy booting or ACC reseting went away.. Its a crapshoot where even at stock HT it can be buggy ..

Slowly raising the htt and tweaking the HT multis is what gave me a sweet spot of 100% stability...


For every Oc i do on this rig ,,
i slowly tweak for Max HT and HTT..
I Note which multis and HTT speed causes what to happen( Crash or NoCrash)..

I then stick to something that always boots and shuts off Cold and will restart after being on for Hours... This is by far the Most finicky mobo ive used that dint like higher than 269htt using DDR2.

Oh,,Im always below the Max 1mhz (gonna Wigout and Blow up Mode)

P.S. F10 after the weekend.. Will post what i find Monday,,Just working on 4wheel projects..No time lately.

I have settings as:

HT@2000
CPU@17.5x200
HTT@200
NB@200x12
RAM@800

so recommending if I get them out of the default zone even just a bit may help with the booting and restarting issues? So Ex:

HTT@225
CPU@16x225 (bump to 3.6Ghz)
HT@2250 (10x multi)
RAM@900
NB@2475 (11x multi)

I was wondering if adding +.250 is safe on air

my current setting are cpu 1.475v
n/b 1.4v
s/b 1.4v
n/b to cpu vid 1.4v

running n/b at 2800 and cpu at 20x200=4.0ghz

You mean CPU_NB?

Theres a Northbridge voltage which you can keep at stock along with the southbridge voltage. SB should not be that high, it'l burn.

CPU_NB is safe up to 1.45v.

Thx for the help shouldn't I leave the n/b voltage at 1.4v because of my n/b speed being set at 2800? I changed the s/b voltage as you suggested and for some reason my thuban need more CPU voltage than most to hit 4.0ghz. I think thx max voltage is 1.5v but I'm not sure.

I think that for high NB clocks, most important is CPU-NB VID not NB voltage.

Beepbeep is right. You may lower your NB & SB voltages, not very good and not gaining anything actually having them in 1.4V. Top 1.25V should be fine.

[richierich]

Yep the Thuban IMC doesn't need as high of a cpu-nb voltage anymore.

[sniperbob]

Does this thread include 790XTA-UD4 boards too??

[trt740]

Thx to everyone who helped out

here is my new clock 24/7, pardon my crappy ram

[richierich]

Have you tried lowering the HT link speed? 2500MHz is pretty high. I've noticed it being that high causes instability.

will try that thx, have you guys noticed with the newest bios and a x6 , a long pause at the boot screen and then it loads windows

[richierich]

BIOS F8d:

Don't want to try it yet, I got too many presets in the BIOS

tried it but acts the same as f8c takes 40 seconds sometimes to get throught the boot screen

I am using 790X-UD4P (DDR2 version) with 1090T and Bios F10a. Observed couple of issues:

1. Vcore defaults to 1.28v correctly if I don't touch the multplier.
2. Upon overclocking (multi at 20) - default vcore is at 1.44v
3. CNQ/Turbo cannot be turned off - Chip downclocks to 800Mhz on no load regardless of settings in the bios.

Overall OK - runs and overclocks fine. Still some issues that needs to get ironed out. So much for support telling me "board under validation will release bios in couple of weeks". Wonder what kind of validation they do, took me 10 minutes to find these issues

[trt740]

the bios I have sucks the delay on boot is pissing me off.

[gOtVoltage]

F10A Bios....Boots up same speed as the F9/F7/F4 ..I found no differance whill using a X2/X4 PHII...The Boot being slower on X6 i dont know...If your using Raid make shure your AMD RAID OS driver is installed ..This may also help.

Well F10a works for me, no performance increases that I can see, they did fix the spelling error in the BIOS for the Manual Unlocking. Still unable to restart my computer from Windows or a Boot CD causes me to loose the Unlock. So that has not been fixed.

Your on Win 7 anrnt ya... Been running 10A since Sunday Night... @ 4300/2700 on the 555/X4 ...Cold boots at 18c Normal has not dropped the Unlock like the F9 did once in while..
I would turn the PC off and let cool for about 1hour or so and even played with my Vista boot CD..( Dont have Win7)

All is normal so far...Remeber i have experiance what your going through on this Mobo..
So we both know it can be fixed..Its just a pain. All hardware is differnt but simalar at the same time(even Vista to Win7


Will ya post a CPU-Z of Dividers being used and one of the ram timing...

Also list your Volts too please ..
I had your Problem before with the F9 and This Vista install..

It is no longer present with 10A for me...

I have already clocked the same 4444mhz+X4 as i had with F9...
Some time this week ill see if i can go over the 270htt Wall which was on F9 for this CPU...
I have a funny feeling that one of your Voltage/HT settings may be the whole problem . Ive noticed if i used 13xHT while raising HTT and using800/ ram divider creates a conflict with booting..Seems certain freqencies are on the border of Stability when i use the 13x with certain HTT/HT settings.



Voltage for the Mobo is not a problem....It easily handles 1.62volts 24/7 @ 4300mhz..All Bioses

I doubt it, I was able to hit 1235 CAS 5 and 1070 CAS 4 on the 790X-UD4P board...I dont think that Thuban will be much help and it's probably ram dependent.



"Munaul" LOL

Actually i believe Thurban and a good bios will be Night and day Beep,,

His ram could be a factor..looks more like a HT conflict , seeing i have had the Same problem.

This mobo is very finicky when it come to HT/HTT using ram and what divider is being used.Especially if Cold , His mobo may want more Volts for the NBchipset or SB...

As for ram just a few that ive used on this Mobo.
Ive tried several Sticks,,
One of which refused to play nice.
Corsairs(DOMINATORS 1.2 dont like this Mobo..

My Ballistics(6400's Cas4's) and Patriots do(6400's Cas 4's and 9600's Cas5's..Has to do with Bios timing and tuning on what ram will work best... My Dominators would crpshoot @ 1150 or slower no matter the timing and sometimes just hang me on .
...OCZ' golds Vista 4gigs did great 1150mhz, The Balisstics (6400) @ 1100mhz and my 2.3v 1230mhz(9600)Vipers love it.

His Mobo can be one of those that wants more juice to be stable(especially when Cold..As for what the HT and SB may want..CPU-NB is usually CPU dependant and always on this Mobo has liked to be run around 1.3-1.35v even if im on 2gigs or 4,, or at 2400/or 2800nb..

Dosnt matter if i used a 430/550/555/9950/720/ locked or unlocked..They all ran with at least 1.3v or more when clocking the NB ..Not Chipset volts.

The CHipset NB i use 1.325v 24/7 The HT /SB i use 1.3v

Thers something that needs to be tweaked on his Mobo for stability..
HT/or voltage..Seeing Coldbooting and Sleep/hybernate affect it to..Kinda like a low voltage issue..Who knows.

I also had My CMOS corrupted twice with F9 when i was trying to duplicate it. Only Bios that has done it. F10A installed and Booted Cold first time around even when Falshing @ 4300mhz.( Dont Do that) i try wierd things sometimes to get results...I know Even Down to the Resume from Sleep mode too. It came down to My HT/ram divider and what HTT was being used..Although im on a differnt OS than him , i still came up with same/simalar results...

After seeing the Coldboot issue still present with 10A on His ,,
Mine is Not unless i choose to make it happen.

So Lets start from Scratch,,
Could be as simple as setting defaults slowly raising volts till every thing works on cold booting. Then Raise the CPUX divider one step at a time untill
it does it again.. You keep doing this for evey thing that can be changed to OC the Chip such as the HT/HTT settings . Id start with Stock on the 1066 or 800 divider .
Slowly bump things up except for the ram..( help rule out the ram)

Ive found when the HT isnt Stable you can simulate this Cold boot problem on the Mobo..It may even Take Two times to power on..Sometime you need to turn of PSU too and even do a CMOS clear. Even More so Sometimes you cant get in on the BIos the First time around,( that really gets to me with the F9 ,when i first tried it. I also Run Raid and i can make it do it with a single Sata too...

Only Thing i dont have is a Cheapo IDE HD..
Usually this makes Overclocking easier and isnt so much affected by HTT/HT as much as Sata or Raid.


Well get it worked out..
I know "Wall" has a Big peacemaker of a somewhere ,, we need to help him before he uses it

[BrokenWall]

Ok Got Voltage:

I have no problems at all with a cold boot no matter how long the PC has been sitting. Even if I shut her down and instantly turn her back on it starts up, but restarting from Win7 or a Linux Live CD all cause the same issues and loose ACC Settings doing so. But if I turn it off via the power button and turn it right back on she is back to being an unlocked CPU.



thats the current settings plus the settings in BIOS. I haven't really tweaked my ram due to the issues i have been having. But once I get everything back off the ground I will just be upgrading to a Thuban 1090T and a new mobo, but that will take some time.
