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

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.

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.

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.

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

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
