MOVED: I think a bios update for the dka790gx platinum is in order

This topic has been moved to Overclockers & Modding Corner.
https://forum-en.msi.com/index.php?topic=130180.0

I can check these timings using AMD Overdrive 3.02 (AOD).  Performance control lets you play with lots of features in memory timing that are not in the BIOS.  I used it to tighten up on memory timings get memory benchmark >2900 consistently with AOD's benchmarking utility.  I did this at stock settings.
And the problem is there is a bug in the bios.  Least I think it is a bug.  The only time you get EPP limits on the values you can choose in the memory timings configuration screen of the bios is if you set the memory multiplier to 2.66:1, with or without EPP enabled.  Otherwise it puts JDAC 400(DRR2 800) limits on the values.  I want to have the freedom to set my timings to EPP 533 limits(DDR2 1066) when I am using a memory multiplier less than 2.66:1, like 2:1 or 1.66:1, so I don't have to up the voltage to much to get a solid stability test.  I can get a good stability test with the DRAM Voltage set to 2.2, and memory is cheap enough I just might see how long they last like that, but I really want this bug in the bios fixed.  I am sure it is in all of the MSI boards that use ATI 790GX chips.
I have been trying to figure out is enabling EPP does anything except lock you into the EPP timings when you are at 2.66:1.  With EPP set to enabled I should be able to set my timings to CL=5, tRTC=5, tRP=5, tRAS=12-18, tRC=25-31, tWTR=3-5, tWR=8.  Having the freedom to set these to EPP limits at any memory multiplier is crucial to successful overclocking on the nb/ht reference clock.  How can we get MSI to make this a part of the next bios update?  Without this correction, I am limited to tRC=26, tWR=6, tWTR=3, these are the JDAC limits not the EPP limits.  We should see EPP limits if it is enabled.  Least that's what it says in the nearly not informative help side panel.

  • BIOS Update for the MSI GTX670 Power Edition Card

    There is a Bios update for the MSI GTX670 PE video card but it's for a hybrid card. What is meant by a hybrid card and how do I know if this applies to my video card? Any help would be appreciated in advance. Thank you. I do know that I can't for some reason or another install the Msi Update program for this card. It keeps saying that you have to be the administrator and Iam the administrator on my system. I do not understand.

    You can use windows version of it to flash it:
    >>Download NVFLASH for windows<<
    syntax from cmd:
    nvflash -4 -5 -6 myrom.rom [ENTER]
    where myrom.rom will be your vbios file

  • Need a bios update for the MSI g45 gaming boot issue

    When i first start my system, I noticed that the board doesn't boot up correctly even if we set the main boot to be the hard disk. The system boot in the EUFI section not the hard disk. I had to use boot override function to choose the hard disk then the system will boot normaly to the hard disk. 

    This is a user to user forum. For any UEFI/BIOS modifications, MSI Technical needs to be informed. There are no UEFI/BIOS engineers here;
    https://forum-en.msi.com/index.php?topic=107326.0  >> How To Contact MSI <<
    In the boot sub-section, disable the devices you don't want to boot in the BBS properties, then set the boot order to nothing but the HDD with the OS on it. If this doesn't resolve it, then the alternate workaround is exactly what you did with the Override.

  • Does MSI provide Bios Updates for 8800GTX?

    Do they provide bios updates fpr the 8800GTX?

    It's the same problem as 7 month ago.  I'm not sure if i postet the problem here, so I describe it once more.
    When I'm running bios 7.20 on my mainboard everything is fine (I'm running bios 7.20 for 7 month no with no problem, so the PSU (BeQuiet 550W) can't be the problem)). If I change the bios to a higher or a lower version my Windows XP looks like this:
    http://img389.imageshack.us/img389/5262/041000011rv2.jpg
    It doesn't matter if I reinstall VGA driver or use the windows standart one, it always looks like this.
    Vista gives me a bluescreen bevor the Desktop shoud appear.
    I knew to other guys who have the same Mainboard and also have a 8800GTX (ok, twice times other brand but the cards themselves should be equal). The only differnce is that they have a higher VGA-bios version, for example eVGA has Provides an VGA Bios update for the 8800GTX but they don't say what esspecially is fixed.
    So far everything is fine, using bios 7.20 is ok for me, BUT I now want to buy an Intel Q6600 CPU and for that I need to upgrade at least to 7.50.
    So Maybe MSI has a newer bios for their 8800GTX which solves the problem. I'm sure that it is nothing else. Windows has always been fresh installed, VGA driver is always the newest one (Did I say that the Windows VGA driver doesn't work to on XP?) and with bios 7.20 I have no problems, I can play, work, everything so I don't think it's a hardware fault.
    The only differnce between my Mainboard + Graka and the Mainboard + Graka from my friends is the VGA-Bios version. So I thought this must be it.
    I poorly can't try another 8800GTX at my mainboard because they won't give me her cards.

  • BIOS update for P6000

    Is there a BIOS updated for the Pavilion 6000 series ?
    And if so  how do I tell which model I have? (6071 through 6085 and does it matter...)
    This question was solved.
    View Solution.

    Hello ShawnyD,
    There is no BIOS update for the Pavilion P6000 series from what I can tell. You can always find driver updates that are available directly from HP by visiting this link.
    http://goo.gl/7HKZw
    With that being said, there doesn't appear to be much of a difference this time for which model you have as they all have the same drivers.
    Sometimes it may matter as there is always some subtle differences between the versions (there has to be a reason to make a new version doesn't there!).
    On your case you should have a label and that label should include information such as your model number. On some machines it's on the side others it's on the back or even some place it on the top.
    See this link for help in finding the label and then identifying the model number.

  • F.24 BIOS update for 2740p

    I just received an email about a new version of the BIOS available for the 2740p. 
    When I ran the update, I was told that the version of the BIOS was not compatable with my system. 
    The drivers page has the last updated driver being F.23 for the BIOS. 
    Was the F.24 update put out before it was actually ready?

    If the community does not think the Bios is the problem then what could it be ?  I have alrready had the motherboard replaced and the laptop passes all diagnostic tests.   Any help or suggestions are appreciated.  Thank you.
    You should as you did go to your P/N page driver and use the latest Bios listed there looking for bios not supported by your board is asking for trouble. And did you try to revert your current bios to a earlier version? Maybe that is what you should do before looking for a bios that isn't listed for your system.

  • Bios updates for 845 Ultra?

    Is anyone aware of any pending bios updates for this motherboard or has it been put out to pasture ?  I'd still like to see a fix for the warm restart problem when overclocking in addition to the 1.65 core voltage limitation.  Before anyone says that those won't be fixed - I can wish, can't I?  

    I have the 845 Ultra-ARU and I am running my 1.8A at 2.52 GHz with a voltage of 1.71 actual applied volts.  This system is rock stable with a fsb of 140.  I have done the VID-pin mod, however.  I too would also like to see a BIOS update for a couple of reasons.  
    1)  According to the temperatures being reported by PC Alert III, my BIOS, and MBM5, my CPU idles at 50 C and goes up to 67-68 C under a full Prime95 load.  The reason why I think this is faulty is because I have run my computer with the side panel off, and there is no difference in the CPU or system temperature.  Also, when running the Prime95 test, I've put my hand right on the heatsink and it is BARELY warm.  The heatsink is making solid contact with the CPU, so if the CPU was actually at 68 degrees C, the heatsink too would be incredibly warm.  My own hand tells me that it cannot be 152 degrees Fahrenheit.
    2)  THE MEMORY RATIOS ARE GARBAGE!!!!!  I've got a 2.52 GHz CPU that is suffering a bottleneck from the measly 2.0 GB/s that my RAM is able to feed it.  Every other motherboard I've ever seen gives you the options of a couple different memory ratios.  I would at least like the option to run my memory at a different speed than my fsb.  Perhaps a 3:4 ratio could be done?  Just something so that I can try and get a little more bandwidth out of my RAM.  I know that the board is only designed to support PC1600 and PC2100 DDR RAM, but how could it hurt to give the option to support PC2400 or PC2700, maybe even PC3200 DDR RAM?  Plenty of other 845 chipset based boards can do that.  (Not officially, but through a variety of memory ratios.)  I'm just tired of not being able to do anything with my memory.

  • Where is msi vga bios update for GF4 Ti cards?

    It seems like many other card vendors are updating the bios on their GF4 cards for better performance. My friend got a nice performance boost on his winfast from a bios update. Everytime I search on MSI Live Update (I have to update Live Update...whats up with so many versions of a simple download utility) it says there are no vga bios updates for my GF4/4400. I read on these forums that .25 (I think) was a disaster and trashed everybodys cards. Is there news on an improved update?

    Msi are going to be last, and then if they release new bios for G4Ti cards.
    Don´t you now they suck, I would sell my card right now if I could.  
    I'm using Asus DVCR for TV because Wincoder with my version did not support full screen window.
    I got fantastic stupid tips from MSI support, because my MSI-CLOCK and 3D!Turbo don't work.  And it still not work with XP.
    If I had 1$ for hour that i had spent to this card trying to let work right.  I could get better card from other vendor.  I will never get anything with MSI stamp.  I'ts better to spent more money and save time for better thinks.
