Not more than 205mhz FSB with a 875 p/t

[antoitomic]

Hello! I'm french, so please scuse my mistakes of spelling...

I have a DFI lanparty 875P/T and I'm not able be stable with more than 205mhz of FSB. :confused:

My processor is a Celeron 330D cooled with a homemade phase change... With a asus motherboard, I was able to put 230 mhz of FSB (4.6ghz) and I was stable...

With my new DFI, I can't do more than 4.1ghz...

My ram memory is a PQI pc 3200 (a sort of noname) which is juste stable at 220mhz, so it should work fine at 215mhz for exemple...

I also can't unsyncronise my ram with the FSB, the only choices i have in my BIOS are auto, 266 and 333, with 266, the ram is syncronised...

I'm sorry, i'm probably not very easy to understand but i do my best... If you could help me, It would be wonderful! :nod:

My Bios is 03/25/05, should I flash it?

 

thanks a lot

1. Update to the 06/27/2005 BETA BIOS. Make sure you read and understand the disclaimer at the top of the page. The BIOS can be found on this page:

2. Under Advanced Chipset Features, make sure the following options are set:

• Tune Memory Timing: User Defined
  
• Fine Tune Memory Timing: Auto
  
• DRAM Timing Selectable: Manual
  
• Fast Chip Select: Disabled
  
• CPC Addr/Control: Disabled
  
• Selective CPC: Disabled
  
• Soft Patch Mode: Disabled
  

3. Under Genie BIOS Settings, make sure the following options are set:

• Async AGP/PCI Clk: 66/33
  
• Auto Detect PCI Clock: Disabled
  
• Spread Spectrum: Disabled
  

Let us know how it goes.

Is there any bugs with this BIOS? have you ever tested it?

Is there a problem with the BIOS i already have?

 

thanks a lot for your very useful help!!

[red930]

From testing, I have found the 06/27/2005 BIOS, along with the settings I listed, works much better with Celeron D CPUs.

thanks a lot, i will test it tomorow...

To flash the BIOS i need a floppy, i can't do it on windows like with other motherboards?

 

I've never flashed a bios this way, i'm a bit nervous...

Give me some time to create a automated boot disk creator with the required files.

 

I am very busy at this point and it may take several days to produce said diskette creator.

[antoitomic]

You would do that for me? :eek2:

With such a disc i would only have to put it in my dvd drive and my BIOS would be flashed? Did i understand well?

[red930]

The automated diskette creator I make would be used in a floppy disk drive.

[antoitomic]

and i would only have to put this floppy in my floppy drive for my bios to be flashed, i would only have to follow a few easy steps? It's perfect for me because i'm very nervous to flash my BIOS..

[red930]

It is as fully automatic as I can make it.

 

Here is how it will work:

• I e-mail you the diskette creator with the updated BIOS specific to your motherboard;
  
• You download the BIOS disk creator to your hard drive;
  
• Go to the folder you saved the file into and change the last 3 letters from XEX to EXE;
  
• Insert a blank, error free floppy diskette into your floppy drive;
  
• Double-click on the renamed file;
  
• Click OK to the notification window that comes-up;
  
• Once the program is done, click OK to the last notification window that comes up;
  
• With the floppy diskette still in the floppy drive, reboot the computer;
  
• The diskette will boot and proceed to flash your BIOS with the latest version;
  
• Once completed, it will ask you to reboot your computer, please do;
  
• Remove diskette;
  
• Get into BIOS and load optimal defaults, save and reboot;
  

And there you go.

amazing!

when will you be able to send me this disk creator?

 

 

 

edit : my bios says my cpu temp is 75°C !!!!!!!!

but there is a phase change system on it and it should be at -20°C...

Are the DFI temperature sensor working or is there any bug with them?
