post #1 of 7
Thread Starter 
So im trying to OC my amd 1055T and i cant get into windows at 4004mhz

settings im using
multiplier 14.0
bus speed 286
nb 2800
voltage 1.45
dram voltage 1.65
dram 1525mhz

any thoughts on what might be wrong?

As you don't have a Black Edition processor, you are pretty much limited with the overclocking because your CPU - Multiplier is locked. From the info you provided it seems that the FSB is causing the problem i.e 286 MHz may be a bit too high on that Motherboard. So first of all, i recommend you to find the max HTT/FSB that you mobo can pump before OC'ing the processor or anything as OC'ing with FSB affects the whole system. Now if you mobo surpasses 288MHz bus speed at-least , then try lowering the CPU-NB for the sake of stability. Also your HT-link shouldn't be more than 2000 MHz.

Now if your mobo alone fails at 288MHz Bus-Speed while finding the Max-FSB, there you are and you can go to bed smile.gif

Thats not how we role at OCN... here you post to learn to overclock, which is the whole point of forums, LEARNING! biggrin.gif

=========================================================================
OK Basic Overclocking Guide 101 for the novice overclocker: Intel and AMD
___________________________________________________________________
First things first:
To make sure that you can even begin to overclock your computer, make sure you have a custom built PC, and not an OEM prebuilt PC, please refer to the following link to see if you have a prebuilt PC, and see the pros and cons of Both: http://www.overclock.net/off-topic/1043930-prebuilt-pc-vs-custop-built-pc.html#post13900478

Now on to requirements:

Hardware:

-A motherboard that supports overclocking
-A good CPU cooler
-A well ventilated case

Software:
-Prime 95
-CoreTemp
-Benchmarking software like Super PI or 3Dmark Vantage
-all the latest drivers for your components
-CPU-Z
-GPU-Z
______________________________________
Now an explanation of what overclocking is and how it works:

Overclocking is basically the process of making your processor run faster than it is specified for at the factory. These speeds are today measured in Ghz, and Mhz (GigaHertz and MegaHertz) An example of an overclock is taking an intel core i7 860 CPU, which runs at 2.80GHz, and overclocking it to 4.1GHz. to calculate these speeds, there are 2 numbers to look for in your BIOS (basic input Output system). your base clock, and your CPU multiplier. You take the base clock, and multiply it by your multiplier to get your frequency. Sounds simple right? well it is once you get the hang of it. But there are a few other things to know, and we will soon go into the details.
__________________________________________

WARNING: OVERCLOCKING WILL IN MOST CASES VOID YOUR WARRENTY, WE AT OCN ARE NOT RESPONSIBLE FOR ANY PART DAMAGE THAT MAY OCCURE DURING YOUR OVERCLOCK!

NOTICE: NOT ALL CPU'S ARE CAPABLE OF ACHIEVING THE SAME SPEEDS, ALL CHIPS ARE DIFFERENT ONE WAY OR ANOTHER, SOME PEOPLE MAY BE ABLE TO ACHIEVE CERTAIN SPEEDS AT LOWER VOLTAGES THAN YOU, AND SOME MAY HAVE CHIPS THAT OVERCLOCK FURTHER THAN YOURS.

BEFORE OVERCLOCKING: Please disable any power saving features, like Speedstep Technology, and disable any CE1 support.
________________________________________________
Now that may seem a little scary, but if you follow basic cautions and rules, your hardware should survive, and you will soon have a free performance boost. Now on to the Guide.
________________________________________________

AMD and Intel processor types:

AMD has been a very respectable microprocessor manufacturer for many years, and have long come to make today's processors, an amazing value, and compete with intel to make faster processors. Intel is also a very respectable manufacturer, and a leading manufacture in high end chips and server grade components.

Generally there are 2 different types of CPU's that overclockers look at. CPU's with locked and unlocked multipliers. A locked multiplier means that you can only change the frequency of the CPU by altering its base clock, which means that it is much harder to overclock than an unlocked processor. with an unlocked multiplier, your CPU can be overclocked by bumping up the multiplier, and then bumping up your core voltage. however when you have a locked multiplier, you are forced to overclock via the base clock, which means you have to tinker with PLL voltage, and RAM Speeds and timings, and all those nasty things. however it really isnt that difficult after you get to know them.

On the AMD side, you can identify an unlocked CPU by the naming scheme. All of the AMD processors with the name "Black Edition" in its name are unlocked and ready to role. So an example of this is the AMD Phenom II x6 1090T Black Edition. Black edition is also called BE for short. AMD tends to have more unlocked processors at a consumer level price range (100 -300 dollars) than intel, and they have much more value oriented products than intel, which give AMD an edge over intel.

On the Intel side, things get a little more complicated. Intels processors can be identified as unlocked with its name scheme as well. All of Intels chips that are Extreme edition, are unlocked and ready, however they used to be typically in the $1000 + price range, and were very unpopular to the mainstream user. however recently, intel has release a new naming scheme, and adding a "K" to the end of some processors names. Those are the mainstream priced unlocked processors, and are ready to role. This give Intel the ability to provide an unlocked multiplier, and all the incredible processing power of intel at a reasonable price range, which give Intel an edge over AMD as well.

______________________________________________
Overclocking an unlocked CPU:

You have either an intel Extreme or K series processor, or a black edition processor from AMD. Congratulations, you will have an easy time overclocking your chip, and are more likely to be limited by temperatures than instability.

to overclock an unlocked multiplier, go to the performance section of your BIOS and bump up your multiplier. than go to windows and start a stability test for 30 minutes, if it sails smooth, then go into the BIOS and repeat, until you have reached a point where the system is too unstable to run Prime 95 for 30 minutes, or you cant get into windows. Now bump up your core voltage by 0.25V at a time until you can get stable for 1 hour of prime 95, keep repeating until you notice your core temperatures on your CPU while running prime 95 go past 70'C ( measured using CoreTemp).

after you've reached a point where you have a nice overclock, and want to keep it, run your stability test for 24-48 hours, to ensure stability. if it fails somewhere in between, simply give it more power with a core voltage bump.



Locked CPU Overclocking:

You have just bought a CPU with a locked multiplier, no worries, you can still overclock, but it will be a little more challenging.

To overclock a locked CPU, increase the base clock of your CPU, by 100MHz at a time (after being multiplied) and test for 30 minutes, until you have hit the temperature mark. then test for instability with prime 95 for 24-48 hours, or run Intel Burn Test. Now when you change the base clock, your RAM speed also changed automatically. so you will also need to increase your CPU PLL voltage, and your DRAM voltage, to compensate for the increase in RAM speed. Sometimes RAM also cant handle higher speeds, on account of the RAM timings, so if your RAM timings are really tight (7-7-7-24) you may want to loosen it to a higher timing (9-9-9-24).

For further details on your processors overclocking, refer to the overclocks of other people, and see what numbers they got, and what they did to get the system stable, as it may help you as well.

wait .. don't give up too early. If you are a gamer , surely at the default clock speed [ i.e 2.8GHz ], your CPU would be a huge bottle neck for any descend graphics card out there. So can you try with a bus speed of 272 ?? So that it would be 272 x 14= 3808 MHz, which is the sweet spot for these AMD processor's.

Now if you are not a gamer or 3D developer , everything default is your best bet. smile.gif

Like J.M.D has said, 272 for the FSB really is the sweet spot for this chip. I like to run my FSB at 275 to give me "rounder" numbers. I've posted my settings below to give you a reference point.

FSB/Multiplier: 275MHz
CPU Speed: 3850 MHz
NB Speed: 2750MHz
CPU Voltage: 1.5v*
CPU-NB Voltage: 1.375v
RAM Speed: 1832MHz*
HT Link Speed: 2200MHz*
Motherboard: ASRock 970 Extreme 3

*Notes:

- I've got my voltage at 1.5 because my mobo overclocks better without LLC(LLC bumps your voltage to compensate for drops in voltage)
- My gskill ram runs fine at 1832MHz but you might want to try a lower speed depending on your ram and it's stock speeds/timings. Also, you might have to bump your ram voltage.
- Keep your HT link between 2000 and 2200MHz. I've found that an HT link over 2200MHz can cause instability.

So put your FSB around 272 or 275 and try to get everything else stable. Be sure to stress test as you go and keep an eye on your temps. And finally, don't go looking for someone to overclock your cpu for you but instead, ask questions here on the forums and learn how to do it your self.

Yah so originally I was trying for 3.8ghz, Ill give ur settings a go, I was fairly stable with 1.45v @ 3.8 but i noticed in CPUZ that under full load it was 1.488v - 1.500v so if i bump my voltages higher like 1.47v or so if i need to will it go over the 1.5v under full load? seemed odd to me that i set it 1.45 and it went to 1.5v under fullload from Prime95 Also i think i have a decent board, I saw on the AMD 1055T owners club thread that a guy was able to get 4.7ghz with the same board and processor as i have(i know not all clock the same and hes prob full watercooling) but seeing as how I have the same board i think im probably good on that aspect. see when i first OC i was just leaving the NB on auto and its voltages on auto because the guy from Linustechtips did so it was alright for a first attempt, now with this knowledge i will try again. But i would like to see an answer about my voltages going fairly high in CPUZ underfull load, I was only @3.8ghz that time and saw 1.488v - 1.5v with 50C temps using the H100

Iam using some patriot 2x4gb 2000mhz ram, and i had the voltage at 1.65v but I was underclocking it to 14-- MHZ using the divider
