So i have finally found out (i hope) why my system wont boot when there is 4gb RAM installed, i need the new bios: 1103 i believe is the correct version i need. So now i need to install the new bios, problem is i have never installed new bios and i have read the instructions on the asus website saying that i need a floppy drive. However i dont have a floppy in my new comp and i dont feel like attaching one. I read in a forum post on asus however that someone used their thumbdrive using asus's EZflash utility to install their new bios. Does anyone here know how exactly to do this? Any help at all would be greatly appreciated.


Specs: Intel e6600, EVGA 8800GTX, P5N32-E SLI mobo, 320GB Sata Seagate running Vista Ult 64-bit, 160GB Sata Seagate running Xp Pro, 4GB Corsair XMS ddr2 pc6400 5-5-5-12

ASUS update tool method . Download the correct new BIOS from the ASUS website to your desktop. From the Start menu, open ASUS Update Tool. From the dropdown select 'Update BIOS from a file'. Select the new correct BIOS file you have downloaded to your desktop. Flash BIOS. You are the proud new owner of a new BIOS. These instructions are in your MB manual under 'Update BIOS from ASUS update tool'. Proceed at your own risk.

Be sure to set the memory voltage to mfg. specs in BIOS. 2.0-2.1 volts should work for 4 DIMMS.

The latest bios is 1203 (I have 1201 which is way more stable than 1103). I have read lots of people have problems when flashing from Windows. Easier to copy the file to memory stick (no floppy disk needed), and flash it directly from BIOS.

Roughly like this:

1) Copy the bios to the root of a memory stick (remember to unzip if zipped)
2) Reboot and go to BIOS
3) Go to EZflash from bios, don't remember exactly where it is, but one the menus
4) EZflash shows the file listing of your memory stick
5) Select the bios you want to flash
6) EZflash verifies the BIOS and updates it (if I remember correctly it asks you if you really want to flash as well)
7) Computer reboots after the flash and you are done!

Remember to install 4GB memory patch for Vista.

I am running 4 GBs of memory in Vista 32 and XP pro with my ASUS P5B. I have not installed a memory patch that I can recall. Can you point me to the patch?

Im have never had a single problem updating my Bios as I described and I own numerous ASUS boards I update regularily. The method is described in the MB manual and the ASUS Update Tool verifies the correct BIOS too. I do not recommend updating your BIOS over the internet.

well now im confused as to witch ver i should update to. I read on the Asus forum that people were having problems with the latest drivers (1203 i think) and that i should use the 1103. However i forgot to check the date on that post as it could be old. Since you are using the 1201ver do you think i should update to that? And badge i am going to try the Asus update tool and if that doesnt work then i will work my way from there. Thanks.

I usually update to the latest 'non BETA' BIOS version. BETA is still in testing. I don't have your particular MB. Yeah, it couldn't be easier using the ASUS Update Tool. It should be a breeze for you. Look it up in your manual and follow the instructions (the same as mine BTW).

I can not thank you enough badge! It worked perfectly and took all of about 3 mins. It booted fine and vista even detects 4gb. If i could help you with anything ever just let me know. Again thanks TONS!

That's great!

Well it was "great" now im getting the BSOD. Arg, so now im pretty sure i just have to install the vista patch to allow 4gb to run properly i am also going to check to see if there are more recent drivers out for my Mobo. I thinked i jinxed myself by getting so excited, i just have to have this thing fixed by Tuesday so i can play Bioshock in all its glory. One more thing, last time when i tried to install the update i had 3gb of memory installed and the patch wouldnt install do i have to have only two for it to recongize that i need the patch?

You may need to go into BIO and set the memory voltage to mfg. specs. Memory voltage set to 2.0-2.1 volts should work.
August 17, 2007 5:37:22 PM

I will give that a try. Just seems odd to me that it worked for about three hours then i had one BSOD and now it when i select vista from my duel boot menu BSOD immediatley. However it does this when i select xp too so you may be correct. I looked on the corsair website and it said 2.1v so ill change it to that first. Is there anything else in bios that i should change?

I have a dual boot Vista 32, xp pro with ASUS P5B and Q6600 with 4 GB RAM. I had to set the memory voltage to 2.1 volt in BIOS to get the system to run properly. Many times when you have system crashes while trying to run software (load an operationg system) it is the RAM causing the problem. The only memory 'patch' I have seen is for 64 bit OS.
August 17, 2007 6:28:05 PM

That sounds correct because the first time i had the problem was when i tried to run Far Cry (i.e running software). So i will try that when i get home and keep you updated. Thanks again man, you have been a lifesavor so far!

So it turns out after all this time is was a faulty DIMM. I decided to do some more testing with my two new DIMMS, so I tried to get my comp to boot with just one of the new DIMM's in, "beep", thats all i got. But however i believe the help i got in the beginning solved a problem i probably would have faced after i got it replaced. So again thanks a ton badge i owe you one!
