AMD 965 X4 BE Overclocking core.

post #1 of 7
Thread Starter 
I have currently AMD 965 X4 BE running X18 multiplier I was having trouble with voltages, So I decided to let the system decide that for me and kept it on auto. Running prime 95 for 6 hours completely stable and monitering the core voltage jumps from time to time from 1.392-1.404 volts so a simple 200mhz overclock from 3.4ghz to 3.6ghz...Also with this damage my system and cut the life drastically on my machine?

Never let the voltages on auto on Vcore for CPU, cuz it always overvolt it. If you are gonna run the cpu at stock settings at 3.4 ghz you can leave it at 1.35v for cpu (This voltage is the stock voltage for this cpu). I have the same cpu as yours and when I first overclocked my cpu I could get to 3.6 ghz on 1.35v easy but after 3.7ghz it needs alot more like 1.4v, but there is some tweaking to get higher clocks on lower voltages, but I think you are rather new so if you wanna overclock just a litle , you can safety overclock to 3.6ghz on 1.35v.

Now I got my cpu speed at 3.8ghz at 1.368v with some special tweaking tongue.gif

anyway

Overclocking is always dangerous, if you dont have the right cooling system. You must first make sure your PC is cool enough to overclock if it is you are good to go, and 200mhz its like nothing, most of the HEAT comes from the voltages not from cpu speed, getting highest cpu speed on the lowest possible voltage is always the best way to go. If you get bluescreen or anything when u overclock dont be afraid, it only means cpu didnt get enough power to operate that "fast". Its only dangerous for the cpu on 1.5v on super high overclocks, dont forget you have a black edition (BE) cpu this cpu are meant to overclock, you can safely overclock to 3.6ghz at 1.35vcore, if you STILL have voltage problem which I think you should not, then 1.375v is the way to go but I think thats kinda high for so litle overclock, I managed to even get 1.325v on 3.6ghz

yeah I have a friend who is real good with this stuff and has the same cpu and is somehow going to 4.8-5.0 but with going to water-cooling that is. His volts are like 1.466 or something along those lines.....Anyways. Im actually trying to run at 4.00GHZ and you think that with jacking the multiplier and putting the volts say 1.41 should do? also another primary concern is I dont wanna basically screw my cpu up. so what are the signs that I should stay away or lover overclock. Besides the obvious of BSOD.

For 4 ghz I think it needs around 1.45-1.475v, but you should overclock step by step not going from 3.4 to 4ghz instant, go like 3.6, 3.8 then 4 ghz. Also when you have overclocked to 4ghz there is other stuff to make it stable, its not just cpu speed. I will tell my settings for 3.8ghz

First you need

CPU load line calibration set to Extreme (if you have a asus board) - This will help in cpu loads, sometimmes voltage will throttle down and make you crash.

CPU Power phase control to Extreme - This settings makes your cpu use more power which helps alot in overclocking, there is 3 type, Standard, Optimized (this setting is best for saving electricity and performace at the same time), and extreme is full power.

CPU Power duty to Extreme - This settings also helps with overclocking and gives you full phase power all the time, the other one dont remember calcuate the power from heat inside ur pc so 1 spot doesnt get overheated etc, in the long turn this setting will get useless so just go extreme.

CPU spread spectrum DISABLED - Its super important to make this setting to disabled it will help to overclock alot, everyone who overclocks always disables this.

This is pretty much I hope ur overclock goes well.

The signs of bad overlock is just BSOD and heat, so try to balance with the settings, voltages and heat.

You cant just crank up multipler and voltages , you have to give the right powers and stuff before doing that, and that will make you give higher overlocks on lower settings, like me, I got 3.8gz at 1.368v thats amazing.

then it comes CPU/NB speed oh man this is the godmode stock is 2000mhz, When you overclock your cpu/nb speed, you have to overclock always the CPU/NB aswell or u will kinda bottleneck the cpu and ram. If lets say you have a 1600mhz RAM that ram is 800mhz right? so (800*2) = 1600mhz and NB shoudl always be 3 times faster then ur ram, but it can always be higher of course so 800*3 = 2400 NB. that will give you overral performance boost between cpu and memory controller without overclocking FSB and RAM! yeahh

But remember the max ram for 965 is 1333 so you dont need 1600mhz, just go with CPU/NB 2400-2600 and increase the CPU/NB voltage between 1.2 - 1.3, dont ever go above 1.35v.

I got mine at 3.8 ghz/1.368v and 2600 NB/1.25v the performance is amazing, you will notice higher performance at memory WEI (windows index) when you re-run the test. Mine went from 7.5 to 7.7 just from going 2000mhz to 2600mhz on CPU/NB.

Find the Phenom II OC guide and read it thoroughly. Proper overclocking is done with manuall settings on almost everthing, for control of variables.

alright, well ive messed with voltages and for kicks I set everything back to factory and funny enough Running stock x18 multi the core is volting at 1.42 which is higher than what i had with the 3.6 so basically leaving auto voltage on and hitting x19 multi wouldn't that be a better solution entirely. and Messing with the FSB and all that "FUN" stuff. is seriously out of my knowledge base. I mean Im no idiot I know how to overclock to a point just I mainly work with intel which is completely diff with volt ranges. considering AMD is running high wattage. So I think for the time being im just gonna run stock settings like I never messed with anything. When I get the cash I will purchase an corsair H100 cpu cooler and then Ill re visit overclocking, I do appreciate you taking your time and giving me useful knowledge. You guys here are so friendly.

best of luck,
-Chase
