How I know my stability for my overclock ?
post #12 of 40
if it boots. once it boots fine, get a program called prime95, it stress tests your cpu, run that for a bit and watch your temps for overheating
if it goes above like 65C or freezes, then you need to back down on the overclock or adjust settings for stability

means that my CPu temp cannot be over than 65 c , below that was fine ?
i only need adjust the clock frequency ? or i need adjust others things as well to increase performance and stabality ?

Nice rig you got there thumb.gif

first off, you have 1600 mhz ram, which isnt good or bad but it gives less room to overclock.
well you could overclock the ram too, take it from me that it isnt something you want to start with as a beginner in overclocking tongue.gif
so try to keep the ram at 1600 MHz. the eazyest way would be to let the FSB at 200 mhz, set the RAM at 1600 and go on to CPU.

to find a stable overclock the best way i think is to just set cpu at 4600 MHz, and add voltage until it's stable (small amounts a time) and watch those temps.
if you reach max voltage and it still isnt stable, go for a lower clock, and try again.

to check stability use prime 95.

one hour for a somehow what stable check and 12+ hours for full stability.

good luck overclocking thumb.gif

what is the FSB ?
which volatage should be added to increase the stability ?
there got lots of voltage in my bios

only touch the vcore voltage, the fsb is the thing that is 200

other word for fsb is htt i think

(fsb stands for front side bus)

The higher the vcore voltage the more high frequency I can go ?
post #18 of 40
well, yeah in theory.
but watch out as every proccesor has it's max safe limit. don't go over that limit.

and more voltage = more temp.

the voltage increases exponentially, that means that for instance:

cpu speed is 3000mhz, 1.3 volt
overclock is 3300 mhz voltage needed is 1.325 volt

only 0.025 voltage more is needed, but with higher overclocks:

speed is 4500 mhz, 1.50 volt

volt needed for 4600 mhz is 1.65 volt

thats a big difference (those numbers are just speculations)

oh and with overclocking, don't do more then one thing at a time.


you can pm me if you have any problems wink.gif

In theory yes, but it gets a bit more complicated than that.

AMD has an actually pretty good guide if you are an absolute beginner to overclocking:

http://sites.amd.com/us/Documents/AMD_FX_Performance_Tuning_Guide.pdf

Basically when it comes to voltage, you don't want to raise the vcore above 1.5v... If you do, you risk quick degradation of your CPU, the FX processors don't handle anything above 1.5 very well.

Additionally, the higher the voltage the more heat that is put out, and the more energy that is used. AMD processors by nature run very cool.. The max temp on Bulldozer is 61C, I suggest while overclocking you keep the temperatures below 55C. Some of the other guys here have said 65C, your CPU won't dare stay stable at that. You should have no problem with an H100 honestly. But when it comes to overclocking, it is best to find the maximum frequency your chip can hit at 1.5v while staying under 55C, and then your goal is to see how far you can tweak the voltage down while keeping absolute stability. The last part takes a lot of testing..

If you do all this, read some guides, and take it one step at a time you should be able to hit 4.5 - 5GHz. thumb.gif

To figure out your frequency, it's Multiplier X FSB = CPU Frequency.

The FSB at stock is 200, I wouldn't touch that because it will change your memory speeds in addition to the CPU. You always want to work on one component at a time, because if something goes wrong then you don't know how to fix it.

Anyway for example, 5GHz:

Multiplier 25x X FSB 200 = 5000MHz.

Also after you are done on the CPU, you can work on overclocking the RAM if you'd like. You'll just have to lower the multiplier for the CPU to compensate as you raise the FSB to overclock the memory..

so can i set the vcore voltage to 1.5v and i slowly increase the CPu frequency ? after CPu get about 55 c then i stop increase those things and just get it to be stable ?
