AMD Phenom II X4 B50

post #1 of 12
Thread Starter 
Hi,

I am new to overclok.net and I dont know much about overclocking. My cpu is AMD Phenom II X4 B50 unlocked from amd phenom ii x2 550 and runs at 3100 MHz. I have 4 GB Corsair RAM and I am running Win 8. I want to overclock it. (I know that the clock ratio is set from the bios's mb intelligent tweaker but thats all i know.) I need help to what ratio I should set the cpu clock and the voltage, dram etc. I will try to give any other information if anyone wants (i dont know what information to give since i am a noob smile.gif) so any help will be appreciated. Thanks... BTW i dont know if taht will be useful but as far as i remember voltage was 1600 or sth like that

you should try looking at the guides already available here and elsewhere.

http://www.overclock.net/t/525113/phenom-ii-overclocking-guide/0_80

i wouldn't bother with overclocking the ram/nb/ht until you've understood and read the guides here; they're a little more advanced and involve tuning more than anything.

you can start by filling in your pc's parts list and put it in your signature to better help us help you, or just post your:

CPU, Motherboard, RAM, GPU, PSU, cooling, and anything else you've put together to make your pc go.

Ok i have read those (even if i didnt understand much)
CPU: AMD Phenom II X4 B50 Unlocked from AMD phenom ii x2 550 Black Edition
mobo: gigabyte ga-ma770t-ud3p
ram: corsair 2x2
gpu: asus nvidia gtx 560 ti 448 cores limited edition (1280 MB)
psu: cooler master 460 watt rs460 pcap a3
cooling: i use the heatsink and fan given with the processor nothing else. the mobo shows cpu temp. in the bios as 40 - 41C but when i start and when i want to play a game i start gamebooster, it always shows as 80 C +- 1C. I dont know if it is true but i have played hours of games without any error like mw3, battlefield 3, assassins creed series etc.

you will be limited by your power supply, motherboard, and cooling.

80c is WAY too hot, even though you haven't experienced any errors, you are significantly decreasing the lifetime of your processor. note that in the overclock.net thread i posted above they don't recommend above 55c for daily use.

I had the same mobo as you do, and mine fried after having this x4 955 at 4 ghz for 2 months. Started crysis 3, played for 2 mins and pc went up in smoke. (Insert "Can it run crysis" joke) So, for a start I wouldn't sugest that mobo for overclocking, maybe something withing reason, to 3.6-3.8 ghz would be ok.
To overclock it you go in bios, check for Advanced tweaker, and there you have the cpu multiplier. Increase it by 0.5 and reboot. Stress test with prime95 for 20 mins and if you don't get a blue screen go back to bios and repeat the step. If you do get a blue screen go back in bios and increase your CPU Voltage. Do NOT go over 1.475 with that mobo.

Repeat the steps until you reached your desired (or max attainable with 1.475 vcore ) clock speed.

Edit: Wow, 80c? The max safe temp for that thing is 60c, or 55c for stability when overclocking. I think the chip has a thermal shutdown at 90c, surprised you didn't hit that yet

by the way cpu-z says my core voltage is 0.992 , multiplier x4, HT link 2009 mhz if that is useful again smile.gif

its downclocking via cool n quiet. not helpful.

can you fill out your rig?

sorry but what is a rig smile.gif excuse me for my noobness... BTW i raised the clock ratio and nb and now i have 3300 mhz.

Rigbuilder upper right, it appears in your signature.

Read the guides I've linked you it'll answer a lot of the questions you have.
Especially gappo and the AM2 guide. AM2 guide probably best written.
