Richierich1212, with your current overclock what is your memory set at (sub-timings, voltage, frequency)? Did you get a chance to isolate your memory to find it's limits? This should give you a nice baseline to play with.

Good luck

How do I isolate my memory to find its limits? It's at 2.1 voltage for stability.

And please add me to the database:
-Phenom II 920
-CACVC AC 0849BPMW
-Revision RB-C2
-3.6GHz (267x13.5)
-1.456v
-CPU-NB voltage (No option for this on my Mobo)
-Northbridge clock (2403MHz @ 1.3v)
-HTT link speed (2136MHz @ 1.2v)
-Biostar TA790GX A2+
-Bios version 764133
-Xigmatek HDT-S1283

Enigma8750

-Phenom II type 940
-CPU stepping CACVC AC 0851CPGW
-Revision RB C2
-max CPU 3690.7, 205 X 18
-CPU voltage 1.424
-CPU-NB voltage 1.3375
-Northbridge clock (AUTO)
-HTT link speed and voltage 1845.5 1.3375
-motherboard used M3A32 Deluxe Wifi/AP
-motherboard BIOS revision 1406
-type of cooling Rosewill Z-5 Air cooling with extreme forced cold air induction
36C Idle 45C stressed

Memory is OCZ HPC running on 2.2 Vdc 6-6-6-18-24-2t @ 820 mhz.

You could possibly tighten the timings on your memory and decrese its voltage and still be stable, just seems like to much volt for what you have...

Well, I'm turning off my PC till the storms pass, I dont have any surge protecting on it

Your NB and HT speeds are both way too fast. Put the HT Multiplier down to maybe x7, and the same for your NB. HT should be as close to 1800 as possible, and NB is the higher the better, but I'm surprised you got it stable at 2400 MHz without a voltage change, honestly.

Richierich1212, your memory is way beyond it's factor clocked speed of 400Mhz (PC6400). Lowering the divider will bring the memory frequency down and should allow you to overclock your processor a bit more. Is that current memory overclock stable in memtest? Usually when finding the maximum limits of your memory (frequency), you would drop the processor multiplier and increase the reference clock speed (HTT).

I'd also following pow3rtr1p's advice on adjusting the rest of your settings.

Hope that helps

(please excuse the retarded question) Can the Phenom II 940 work in a AM3 board? Tigerdirect has the new AM3 board with DDR2 RaM Compatability, was hoping i can get that mobo instead >_> (Already have the cpu)

"The Asus M4A79 Deluxe is the first Socket AM2+ motherboard we've seen that is intended to accommodate both existing Socket AM2+ and upcoming Socket AM3 Phenom processors." Right nevermind...

CACVC AC 0850(i forget the rest) Max stable overclock 3.8GHZ Revision RB-C2
CPU Voltage 1.5875 NB VID 1.45 DDR 2.1v NB Voltage 1.26 HT Voltage 1.28 SB Voltage 1.28
Bios Version 0702. 8GB OCZ Reaper 1066 Ganged, 1800mhz HT link. 19x multi x 200. ACC On auto. Boots and runs at 3.9GHz but some games crash. 4GHZ plus BSOD on windows load screen "page_file_in_nonpage_location". 3.8GHz is prime stable for 4 hours (as long as I tested) with 51 degrees CPU Load temp (idle temp is 34). Unknown Core temp. Windows Vista64 Ultimate.

So far I'm impressed with speed and load times. Broke 20k on 3dmark 06. Not impressed with Overclockablity. I obtained an Identical 800MHz Overclock with my 9950 with the same settings and that ran cooler. Although that was 2.6->3.4 and this is 3.0->3.8

So the PhII gave me an Extra 400MHZ at the same voltage with warmer temps a slower HT link but faster Memory. Its a win in my book but not a devastation. I tried 2000MHz HT Link and it wouldn't even post.

Currently I'm running 3.51GHz at 1.408v. My chip is being rather weird, as if it give it more than 1.425v it becomes unstable, therefore I cannot get anything more than 3.5GHz to even boot into vista. Even running at reference 200MHz its not stable at anything above 3.5GHz. Its just not making sense that more voltage is making it less stable. I checked my PSU with a multimeter, the 12v, 5.5 and 3.3v rails are all spot on.

I have stepping CACVC 0850 BPCW.
Northbridge clock (2106MHz @ 1.35v)
HTT link speed (2106MHz @ 1.25v)
