Well im still doing some research have you tried your memory in all 4 dimms, i know sometimes you have to have them occupy 2 certain slots when only running 2 dimms. I also don't know but im told you can change your ram from gauged to un-gauged and what that means is switching the memory to use 1 dimm per core. I wonder in your case is yours running 1 channel per core, meaning running single channel mode 1 channel per core making the 4 channels. I might be completely wrong but just some thoughts of a few things to check out. I know if i take 2 sticks of memory out and set it manually to 533 it runs in duel channel mode giving me 1066mhz. If i put my other 4 gigs of memory in i go back to 800mhz single channel i believe and that's a memory controller issue with the chip.

System is:

Windows Vista 32bit (atm)
2Gb OCZ CL4-4-4-12 CT1 800mhz

I didnt have this problem as such BUT my PC locked up constantly BSOD mainly with the following errors

dxgmms1.sys OR
ndis.sys OR
win32k.sys

After several days of hair pulling, I did manage to isolate the problem.

It was the new ram - Corsair Dominator 5-5-5-15 2.1v 1066mhz. 2x2Gb sticks

No matter what I did the system would not run stable at 1066mhz on the ram.

I changed back to my older OCZ ram and voila, system stable, no BSOD.

My suggestions to cure the probs.

1. As others have stated, update to newest stable BIOS (no beta's as this did affect mine!)

2. Disable Cool n Quiet. Personally, I have always been an AMD guy (cheap n cheerful. ) and never had this enabled.

3. Definately check your RAM timings and speed. (relax the timings if needed)

4. Check motherboard compatibility with the ram & processor.

I had to change my motherboard from an ASUS M3a32SLI-deluxe when I changed my processor from the Athlon X2 6000+ because of a fault that didn't appear until I slotted an X4 into it.

Dunno if this helps anyone. I am probably just rambling. lol

Thx but xBlade where can I set my cpu to performance? i looked at the control panel but i didn't find it.. My os is windows 7 64 bits. Although i tried to turn off cool n quiet it
wasn't better than with this. It was strange because while i turned ON cool n quiet my phenom II ran at 3.4ghz in load ?__? i don't understand... but i can't overclock even f i put 220x19 in bios it do nothing. i tried with only two ddr stick
but it didn't change anything.

I had the same problem. Simple fix. You have to change power settings to maxium. Create a new power manger, call it what ever you want. Then set it to maxium. click apply and you can over clock or get the 965 amd processor to stay at 3400, while in windows. But for all that don't know it. Even if you use power savings, or balance. Your processor will increase speed or slow down speed depending on the demand of the processor. Windows vista and 7, both are able to use several cores and run at a slower speed, and still perform without a hitch. The plus of it is you use less power. Hope this helps.

hello, my friends how to fix this please?

i like to Unlock CPU potential, AMD X4 Core ? X6 Core
( 100% CPU Performance Boost! )

I did in bios enable but still X4 how?

The frequency working 800GHz how to change to 3,4GHz?

i have:

CPU - AMD Phenom II X4 965 Black Edition 3.4GHz Quad Core Processor

ASROCK N68C-GS UCC

Memory
Corsair Vengeance Performance Memory Module 4GB (1x4GB) DDR3 1600MHz
http://www.cclonline.com/produ...DDR3-1600MHz/RAM0264/


BIG THANKS

You MB does not support CPU's over 95W TDP... you need to get a new board to use your CPU fully. Also you cannot unlock a quad core... it's already got all it's cores in use

thanks my friend, l'll deal whit it

log into the windows 7 admin account ..activate it by using the netuser command in command prompt and then use cpuz and check your cpu speed

ok this saves you energy and also keeps more life on ur cu and temperature ... true...

but what i am concenr is what bout this up and down all the time on the cpu and the volt's i think is not so good cos welll i dont know really i just think is not so good to have the voltages and phases running up and down ?

thx for your time
