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: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
650w antec earthwatts
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.

Please can someone getback to me ASAP and tell me what happened and if i needed to buy this motherboard. Note i am new to building pc's and am very upset as you can imagine!
Thank you in advance.

It probably is compatibility issues. which is why the cpu was running at the slower speed, maybe the mother board cant handle its power requirements and speed.
Websites are normally rubbish with things liek that. e.g they will list an am2 + mo/bo and in its compatibility section only list am2. which to inexperienced buyers/builders can be a bit worrying.

Get back when you get your now hardware :) , hope that sorts it mate.

Having this same issue with my friend's computer I recently upgraded to a Phenom II 955 BE on a Gigabyte motherboard.

Seems to be a BIOS issue, since the motherboard will set the clock multiplier down to x8 when it should be set at x16 for the base speed on the 955 proc.

If you try changing the multiplier to try and manually set it at the base speed we ended up with the same results as you. However, if you clear the CMOS, it should start back up again, in my case we had to clear CMOS a few times for it to properly boot again with the down clocked multiplier.
In my case, we are still waiting for a BIOS update to fix our issue.

Hope your new motherboard works like a charm!
