DFI LP PRO875B rev. B1 + Zalman CNPS7000A-Cu RPM Error


Recommended Posts

When i bought my motherboard and booted up with retial bios.. it displayed cpu fan at correct speed.. 2650-2700rpm

 

..now that i updated to LPPRO875B0409 bios.. on boot screen it shows 5000-5400rpm?!?! after i load to WINXP and load hwdoctor.. it shows correct speed of 2650-2700rpm again..

 

bios glitch?

 

 

speaking of glitches.. would DFI be adding any of those 14x multiplier unlocks like asus does for its canterwood boards?

these are only for FMB1.5 Prescott cpu's (3.4 or higher) on socket775 motherboards. All socket 478 cpu's are hardlocked by Intel. (unless you know something we dont?)

 

is the bios you flashed to a beta bios or a retail bios (and what is the date on it?)

HI AG,

 

i stated the bios i was flashing in my first post already my friend..

and its also on my signature :D

 

 

..now that i updated to LPPRO875B0409 bios .. on boot screen it shows 5000-5400rpm?!?! after i load to WINXP and load hwdoctor.. it shows correct speed of 2650-2700rpm again..

 

thats what the bios is registered as the latest bios on the support page..(unless you know about a newer bios i dont?)

 

 

and I wasnt referring to the socket 775, i was refferring to my other PC... Asus P4C800e Deluxe.. thier new bios allows us 3.4E Prescott users to unlock 18 to 14... maybe you should go have a look at the xtremesystem forums ... it would be a nice feature to add into us 875 Lanparty owners..

lol ok.. let me try to be more clear next time.

 

bios page...

http://www.dfi.com.tw/Support/Download/bio..._FLAG=A&SITE=US

 

and this bios here..

 

PCB Revision B

Date Code 2004/04/09

File LPPRO875B0409.ZIP

Size 332,103 bytes

Description Remove the original one and use new Winflash Utility at URL http://www.dfi.com.tw/Upload/Driver/WinFlash-875Inf.zip if you prefer flashing BIOS with Winflash.

1. Fixed the SATA HDD capacity detection issue.

2. Enabled the detection of FAN with speed 1400 RPM.

3. Fixed Memtest86 V.1.10 issue when using Corsair memory module.

4. To calibrate the temperature display.

Remarks: The full screen logo is removed.

One piece of 1U capacitor should be across over resistor at location R285 for supporting P4EE CPU.

 

and no matter what settings i change in my bios.. my cpu fan shows 5400rpm or so on boot

Yup On Boot it shows incorrect speed and in windows it shows proper speed.. telling me its a DFI bios problem..

 

and everything is still working correctly.. but to pay $230CAD for this motherboard and giving DFI the benifet of the doubt instead of buying another stable P4C800E-Deluxe that works like a charm and has newly updated bios every month or so.. it would be nice to have a glitch free board..

 

for a company that advertising its products as the best.. I'm only hoping it stands up to its claims..

could be just your Zalman...ive plugged in 4 different fans and they all report correctly in bios and in Winbond HW Doctor

 

Thermaltake Smartfan2 80mm adjustable

Enermax 92mm adjustable

SVC special ($1.99 80mm)

Antec blue LED 80mm

 

all the headers report RPM correctly upon boot and in windows for me...you have tried a different fan to make sure? plugged the zalman into another header to see if readings are the same?
