My older card is GF3 Ti200. I bought the GF4 MX440 because my P3 is using TNT2 and performing damn poor. Just thinking of putting the GF3 into my P3 to boost up the performance and at the same time don't want to spend so much and get a GF4 MX440 for the meantime to get my P4 running. Thinking of upgrade to GF4 Ti4200...or maybe looking forward for ATI Radeon card.
Okay, back to the problem...With GF3, it was okay and the system is running AGP4X. The ASUS P4T is i850 chipset using RDRAM and it can only support AGP 1.5V and it seems like the GF4MX440 is AGP 1.5V (AGP 2.0 standard). Boot with GF3 to check the bios, everything looks fine. Then I even flashed the bios to the latest version from ASUS. Still can't work.
I found one interesting thing, that is the USWC (uncacheable speculative write combining) mode in the mobo. It says, if VGA card does not support this, the system will not boot. So I disabled (changed to UC, that was the only choice) it before I insert the GF4 MX440 card. Still no luck. The card was properly put in, no beep from the system, fans were all running, monitor shows nothing (not even boot screen for Bios) and the hard disk lighted up but not running.
I couldn't find the solution till today. Maybe one of you knows what went wrong... I can always try your suggestion as both PCs are now with me.
Well, this is configurations if you need one:
P4 1.7GHz (S423) - clocked to 1.9GHz
2 X 128MB RDRAM
ELSA GF3 Ti200 (Work) changed to Leadtek GF4 MX440(Not work)
ASUS P4T mobo with latest bios
SB live! 5.1 DE
Maxtor 7200rpm HDD
Samsung Syncmaster 753DFX monitor
I guess that's all that relevant. Another thing was that I clocked back to 1.7GHz for my processor but still can't work with the GF4 MX440 card. Now seems like pretty scare to upgrade to GF4 Ti4200.
