anyone tried to put 4x1G ram to p4p800-x? bios reading is less than 3G. Used cpuz and it can detect 4096MB, but system property only written 2.96G for both XP and windows 7.

any fix for this?

i fell win 7 is much faster than xp le using the same rig

just bought it from lelong the 3.4G, but got a broken pin so send back for warranty liao. actually previously i was running on 2.4G on asrock MB, but then i bought the 3 units of p4p800-x quite sometimes and it can fit up to 4 slots of rams.
now i encounter the problem of bios reset each time i switch off the main switch for my CPU after shut down. cmos battery changed, but still the same. any p4p800-x user facing this type of problem as me? if so, what is the solution?

i don't face this problem for my asrock mb.

i've tested 2 board also like that. the other still unopen. i just wanna confirm it this the board behavior or not.

now damn frustrated after i wasted my whole night taking out my asrock replacing with this asus board hoping to see some improvement but ended up.. haiz... felt like wanna place back my asrock back if i can't solve this bios reset as everytimes i needa change the time, sata boot and other setting. really kacau!!


** i can't remember this happen to my 3.4G proc or not as i used it not more than 2 weeks then swap back to 2.4G now. The 2.4G had been running without an issue in the asrock board previously.

i've changed the battery but still same, but miracle happen. it never reset yesterday after i power off the main power for 8 hours.

actually I planned to build a small network for my house with a server and other stuff to test out ma. so got a few board to play around with. by the way, my ASROCK P4i65G mobo also run on the same chipset as asus.

i never used the onboard vga, unless my vga spoilt, but that's just for temporarily. i am suspecting my vga having some problem now ashe ram reading on the bios never show the correct amount as i placed it.

256M.

weird enough. last night i swapped the 9550 with gforce mx-440 and the bios can read the ram memory up to 3.9G and from win7 it show that 3.85G usable instead of 2.5G when i used A9550.

now i am suspecting it is the either ATI, A9550 VGA or my VGA card is having the compatibility issue since using 1 ciplak AGP can display the memory space correctly from the bios!

feeling damn regret upgrading my 478... hope this will be my final upgrade for skt478!!

plz update the list of my item change

gotta agree with u..

i have tested to change some setting on the BIOS and the RAM reading change.. i change the VGA aperture size also will effect the ram.. and it seem like the board can only be stable to a max of 2G ram.. if more than that, I cant get the actual reading of it..
