I need some help overclocking my AMD Phenom II x6 1055t. I have an Asus m5a78l-m lx. I would like to overclock to about 3.6-3.8 ghz but I am a bit confused. On all of the overclocking guide that I have seen on the internet People have been able to change the frequency and the multiplier seperately. I can only seem to adjust the ratio to x4 800 MHz up to x14 2800MHz.
I guess overclocking is not as simple as I expected. What exactly do I need to do to get the speeds I want.
Black edition guide at the top of the section man,
you should be able to adjust your baseclock/Cpu freq from the 200 standard setting in bios somewhere,
and the multiplier as well,
but get into your bios screen, and look around, click tabs, see options that maybe ordinarily 'locked'
you can't screw it up unless you save and exit, if you forget what you've adjusted, just discard and exit instead, no harm done and back to square one
but read the guide to get the idea of what to alter, why and how,
I really can't emphasize that enough, theres no 'fast' way to learn clocking, it takes time and patience
(sometimes lost hardware too )
If your boards multi only goes to x14 though, you need a Cpu speed of 270ish to get 3.8GHz, which is a serious heft, what cooling are you on?
but you are right, overclocking isn't a simple thing
I managed to work out the multiplier thing is was me being an idiot . I have set my multiplier to 14 and my CPU reference clock to 260 MHz. This should give me 3640 MHz.
How do I work out my rams speed because I understand I can't run it over the stock 1333MHz. I can change my memory clock to either 400,533,667, or 800. What sould I use to keep under 1333MHz?
Set it to what it says on the sticks, 1.5v, 9,9,9,24,41 2t or whatever the timings etc are, and remember ddr is double data rate so for 133MHz ram, you manunally set it to 667 or thereabouts the system doubles that to give you 1333MHz
and mind those temps, 60 at load is kind of the edge of the chips limit
Your chip may not reach 4GHz, but its a learning process, you get stable at say 3.4 then try squeezing a little more out,
the restriction you face here is the low multi on that mobo though,
low clockspeed and higher multi is a more stable method of reaching a high clock
I seem to have a barrier that I cannot pass at 3.5 Ghz. If I set it above that and hit f10 my monitors lose signal but my pc keeps running. I have to turn off at the power switch, and I when I reboot it makes me reconfigure my settings. Any ideas on how to get past this?
5 increments would be better if you can, but its whatever the minimum increment on your mobo is,
another general tip is say you want 3.8, set it to that, it will crash so you back it down a touch, try booting agin, and so on, until you find the stable max
Temps and volts obviously to be monitored
Should be written on a label on the stick, usually looks like,
Pc3 12800 1.5v 9,9,9,24,41 2t
first bit tells you its ddr3 then the data speed limit, recommended voltage and finally the important settings that you will enter into bios,
if you look on Cpu-z's memory tab, it tells you which number is which setting http://www.hardwaresecrets.com/article/Understanding-RA... is well worth a read though to help understand timings
