Hi guys,

I come to this honorable forum seeking some help from the better overclocker community on the net.
First of all thanks for taking time to answer me. Also, I want to apologise for my not very good english

I want to OC my processor, i have tried to do it reading guides and forums but i dont get the point.
During 2 weeks i am trying to oc my processor but i cant set it stable, dont know why.
Firts of all, I tried to OC to 4.5 but i was imposible.....
Now i am trying to set it, at least, to 4.2 but i cant do it and i know my config is able to do it.

My specs:
Power: Corsair TX750 750W
CPU: AMD Phenom II 1075T X6 3.0Ghz 125W AM3 Box Not Black Edition (max multiplier x15)
RAM: Corsair Dominator GT PC3-15000 DDR3 1866 6GB 3x2GB CL9
Motherboard: Asus Crosshair IV Formula
Video: Crossfire 2x Sapphire Radeon HD 5770 1GB GDDR5
CPU cooler: Corsair H70 (default fans replaced for two Noctua NF-S12B-FLX-1200 120x120 1200rpm )
Case: Cooler Master HAF 922

If you guys can tell me from where can I start...
I've just set my Bios back to default options to start properly.
Cool'N'Quiet and CP1 are disabled.
If anyone would be able to give me a first BIOS configuration to start i will be very grateful!!

So if you guys believe its possible, my objective is to reach the 4.5 or at least (minimum) 4.2

A lot of thanks for reading my post,
I am sure you guys will be able to help me!!

PD: i can answer pretty fast on the forum

Welcome to OCN

Dude, first of all, 4.5GHz is a DREAM number for a PII x6 processor, very few people reach that (if any). You should aim for 3.7GHz to start with.

How you overclock can be found in various guides, but take it easy, I'm 100% sure you won't get 4.5GHz.

 

[tCoLL]

you're not going to get 4.5 out of that processor. I have a 1090t and can barely get 4.2. Shoot for 4.0 for starters, champ.

Well thats the proof i am not an experto OC'ing xD
And what do you think reaching at least 4.2?

 

[PatRaceTin]

4.5 not easy !!!

Not even that high, aim for 3.7GHz at start, if that goes fine you can try to get it to 4GHz.

For me, I can only get to 3.8GHz, then it's my motherboard that is limiting me to go any further. I think that if I would get a new motherboard I could get a high clock, because I can get 3.8GHz in 1.3 Vcore

Okay, thanks for the answer

I will aim 3.7ghz and if all is allright i will try to reach 4ghz
Anyway, i will post all my progress!
But my knowlendge only allow me to modify bus speed, multiplier, vcore,etc... basic things.
Can you explain me what is the CPU/NB frequency? should i change it ?
Should i modifi NB voltage or CPU/NB voltage ?
Thes two points are the last things i need to learn to start seriously overcloking

And what about Asus TurvoV EVO ??
I know its a sacrilege for pro overclockers xD
But i have read on the internet that is not to bad... and i dont have too much time to overclockign during weeks so is a nice idea? if not what can be the bad things about using this program ?

thanks again

CPU/NB frequency refers to the speed of the memory controller and L3 cache on the cpu. I recommend while you are trying to find your maximum CPU clock to keep this and your RAM speed as close to stock as possible. By doing this, if you have any kind of crash while testing you will be sure that it's the CPU cores being unstable rather than the mess of other things it could be by raising everything at the same time.
Also, some AMD CPU's need more voltage or some tuning on the CPU/NB when running RAM clocked over 1600MHz. I would try and keep the RAM speed down between 1333 and 1600MHz as well while testing the CPU cores.

Okay thanks a lot

For the moment it seems i am stable at 4ghz (have to try during 12h and 24h yet) but i am startinf decreasing vcore to see if i am able to reduce my temps a bit to high.
I will post progress
Thanks guys

Hi again guys,

I am having a lot of trouble trying to reach these 4Ghz
Lets see if someone can help me

4ghz = 267x15
Ram is set to 14XX (dont remember last numbers)
NB Frequency set to 2600

I am not even able to complete 1 hour with prime95 (blend mode) without having one of the cores stopped.
My CPU voltage is set to 1,478 and CP/NB to 1.3v
The problem is that even in 1,478 CPU voltage my max temp has just gonne to 75ºC (max temp). So this voltage is too too much hot but not sufficient for these 4GHZ.....

I live in Barcelona and its very hot now. It might be a problem.

What you guys do you think? Can someone give me a voltage configuration to try if it will work.

If not... Does TurboV EVO autooverclock is so bad ??? Because i am not able to OC myself from BIOS...

Thanks again!

 

[tCoLL]

you're going to fry your cpu, what do you have for cooling?
Be happy with 3.8 dude.

Very bad! any auto overclocking software is bad even if it's in the bios it'll give a boat load of voltage for any given clock therefore more heat :/

 

[PeL4]

Here's my OC when I had a 1075t, it might help you



Good luck

 

[Wildcard36qs]

286 x 14 @ 1.45v should reach 4GHz. Also make sure to bump up your NB to 2800 MHz and throw CPU-NB to 1.3v or so maybe 1.35v

 

[diablo460]

Thanks for answering guys

My cooler is an Corsair H70 (but my CPU still hot

)

Ok i am going to low multiplier and rais cpu bus like wildcard36qs said. I will follow the voltages you gaved me and try if it works.

If it dont works then i'm gonna follow Pel4 configuration see if it will work (where do you live, North-Pole ?? so perfect temps :B )

I will post my progress,

Thanks again guys

 

[Disturbed117]

Also 62c is the max safe temp for thubans.

 

[diablo460]

Hi again guys!

Well... i dont have very good news xD
The thing is that i am on the 3.9Ghz qith 1.42v for CPU and 1.3v for CPU/NB
But the problem is that when I use prime95 i always get an error on the sixth core.... But with OCCT all seems ok...

What should i do? Should i continue overclocking with OCCT ?
The fact is that prime95 gives me an error on the sixth core even if i set up my CPU voltage to 1.5 ... So i am not sure if i should trust prime95 :S

Thanks in advance for your responses

 

[Sisaroth]

I have never heard p95 giving wrong results. Just go for lower OC, with those high amb temperatures you wont get 4.0 GHz with reasonable temperatures, when it is winter you can try to get a higher OC, i think there are other people that change their OCs based on the season.
And what exactly are you gonna do with your PC? overclocking doesnt do that much when it is just for gaming, a good graphics card is far more important.

 

[decimator]

Make sure your HT Link frequency is around 2000MHz or lower and that you turned Turbo Core off. Also, do you have Load Line Calibration on or off? An H70 with push-pull setup should be able to do 4.0GHz easily. I'm thinking that maybe you have LLC on and you're pumping more vcore than you need to through your CPU, which contributes to the abnormally high temps.
