Asus M4A78 Plus Memory Limitaton / Not On Asus Website

That limitation applies to the AMD Processors. I run an M4A79 Deluxe (Previously had an M3A32 MVP Deluxe) and they both had the same limitation since I was running AM2+ processors in both. If you want to use all 4 ram banks you have to run the ram at 800mhz. There are people who have managed to get all 4 banks running stable at 1066 by setting voltage and timings manually in the BIOS but there is no guarantee this will work for everyone.

If you want to overcome this limitation then you need to step up to an AM3 motherboard with DDR3.

Here is the wording from newegg, notice it says the limitation is the processor's design, not the motherboard itself:

DDR2 1066*/800/667

* Due to AMD CPU limitation, DDR2 1066 is supported by AM2+/AM3 CPU for one DIMM per channel only.

Hi
You will find M4A78 Plus here:
For some reason it is not on the US site, only on the global
If you plan to install Windows 7, beware. I bought one a week ago and was not able to install it. It runs very well with XP 32.
If you get it and can install Windows 7 I would love to know how

I installed Win 7 64-bit on my M4A78Plus.After install there was only 1 yellow ? mark in device manager which was ATK00110 acpi utility under system devices.Found that on ASUS site.System specs follow.Also running XP in dual boot

7750 kuma at 3030mhz
2gigs Kingston KHX8500D2K2-2GN from qvl

9800gtx+
OCZ 500w MODXSTREAM PRO

Check your bios version and cpu support,you may need an update.

URGENT HELP NEEDED REGARDING PHENOM II 965 AND MOTHERBOARD ISSUE

hey i really need someones help on here. I have recently built my brand new computer with a phenom II 965 3.4ghz processor, on a gigabyte GAM720-US3 motherboard.

I ordered my build from lambdatek.co.uk and it said these to components were compatible with each other however when i turned my comp on for the 1st time i noticed how the phenom HAD BEEN DOWNCLOCKED TO 1.6GHZ.
I looked on the gigabyte website for this board however to my dissatisfaction my phenom 965 was not listed in the cpu support list, however the phenom II 955 3.2ghz was.

I THEN UPPED THE CLOCK SPEED IN THE BIOS TO 3.4GHZ (WHAT IT SHOULD BE) AND THE COMPUTER THEN TURNED ITSELF OFF AND NOW WILL NOT BOOT AT ALL. I TRIED TO RESET MY BIOS BUT FOR SOME REASON COULDNT (SHOULD I BOTHER TRYING AGAIN??)

Please can someone tell me if this is a compatibility issue or not, or whether i just need to update my bios (god knows how, theres no option for this processor!!) As i now CANNOT GET PAST POST AND THERE IS NO SIGNAL TO MY MONITOR.
BIOS BEEPS ARE NON EXISTENT, yet case fans etc and psu appear to be on, however COMPUTER OCCASIONALY RESTARTS A FEW TIMES on power on S:S:S:S.

NOTE: THE SYSTEM DID ORIGINALLY BOOT AND WORK HOWEVER THE CPU WAS RUNNING AT 1.6GHZ, ALSO RAM HAD BEEN CLOCKED DOWN TO 800MHZ


4gb (2x2gb) ocz blade 1150mhz

asus radeon hd 4870 1gb ddr5
wdc black 500gb
lite on dvd/rw

I spent 700 on my build and im really needing answers so any help is appreciated.
I have purchased another mobo now hoping this will fix all my issues. This being the asus m4a78 pro which apparently is compatible (i notied the m4a78-e mobo just after i ordered it :@:@)

the links to the motherboards are below, the gigabyte being the one that "doesnt work"?? and the asus being the one i have purchased and am hoping to put the components onto in a bid to get the system to work.
