Overclocking Amd Phenom ii x6 1055t

[Thornbird116]

Hello, i have done quite a bit of research on overclocking, but i'm still not sure about it. My question is, can you overclock the AMD Phenom II x6 1055t to 3.2/3ghz just by bumping the FBS? My reason is that i just bought a GTX 660 TF and my processor is bottlenecking me in some games.

My specs:

Mobo: ASRock N68 GS3 UCC
GPU: MSI GTX 660 TF OC Edition
CPU: AMD Phenom II X6 1055t
PSU: Ace 700w
Cooler: Stock cooler 🙁

If i cant OC just by bumping the FBS, is there a stable build i can use to get to 3.2ghz? I dont want to get to 4, or even 3.8, but i really want to get to 3 🙁.

With DDR3 1333 the *sweet spot* for the system clock is 250MHz. Instead of running your RAMs at stock 667/1333 (6.67x200MHz=1333MHz), Your RAMs should be at 533/1066. The result is ...

5.33x250MHz= 1333MHz

Remember that your RAMs are *double-pumped* When CPUz reports 613MHz, your RAMs speed is actually 1226MHz. Fooling around with the math ....

1226MHz / 5.33 means you have your system clock at 230MHz.

How'd I'd do?

How come i failed the CPU-Z though when it was running stable at 3.2ghz? it said FATAL ERROR: Rounding error was 0.5, expected 0.4

Please, master. I need to learn. xD

your target max is 3.2 ghz .. no more ... if you want over than that get better motherboard + CPU cooler after market first .. just a suggestion .. good luck brother

I dont wont anything above 3.2, i was happy with that. The thing is i couldn't pass the Prime95 Blend on it because it said FATAL ERROR: Rounding was 0.5, expected 0.4

is your CPU 95W or 125W ??
already given a good guide from Wisecracker

My cpu is 95w i think, since it works with the MOBO. Any ideas on why my monitor fails to recognize a signal after a OC?

 

[henydiah]

clear CMOS ! .. unplug power AC from PSU , find jumper clear cmos ( remove battery mobo) let @minute

All that means is the settings were unstable. Thats why you need to clear the CMOS if the PC fails to post. You're going to have to raise that voltage man. If not then try for 3.0GHz, but you still may need a voltage bump. While there are thousands of 1055t's, not a single one is the same.

The 1055T Thuban hexcore is 125w.

REMEMBER: When you are running 14x230MHz, your Turbo is 16.5x230MHz, or 3.795Hz!

Don't be afraid to bump your VCore in +0.0125v increments to find stability. As long as your temps stay below 60C.

Your HT link speed should be set on 4x on your nVidia chipset!

I booted into 3.2ghz, and have been running Prime95 for 1 hour now, according to Razer Game Booster my CPU is 56C, my mobo is 73C, Video card is 43C and Hard disc is 50C

I know it's not ideal, but is it safe?

 

[Thornbird116]

Weird, i just checked and CPU-Z says that my CPU is only running at 1.7ghz with a clock multiplier of 7.5. Is this a protection to stop from overheating?

 

[Thornbird116]

Ok, confirming that my processor runs at 3.2ghz stable while idle, and at 1.7ghz under load? Is there a fix for this?

Thermal throttling perhaps? Use a real monitoring program.

Seems to be that the minute it goes above 51C on the CPU, it throttles it

 

[Thornbird116]

I checked in the BIOS, and thermal throttling was on. I'm going to keep it that way because it's better safe than sorry, right? xD

Also, I realized that the side of my case (where all the heat escapes from) was backed up against a wall. I have moved the position of my computer and now the heat can escape, hopefully it wont reach 50C again. If it does, ill go back to stock and wait until i get a new cooler.

 

[Thornbird116]

Back in stock settings, and my CPU still throttles when its over 50C. I didn't think it would reach 50C with stock but apparently it does. I'm now pretty tempted to remove thermal throttling, or just find a way to move it so that it throttles at 55 instead of 50, but i cant find that option in my BIOS. Would putting a house fan on the side where the heat escapes be a good idea? I'm going to clean out dust on my fan later on. Also, in my BIOS I have put it so that my max temp should be 45, but it still goes to 50C.

 

[Thornbird116]

Any suggestions?

 

[henydiah]

second plan get new highend mobo

 

[stickg1]

Not much you can do until you get a decent mobo and cooler.

 

[Thornbird116]

Can someone explain how airflow works, because I'm pretty sure thats the issue. My hard drive is getting close to 50C, because i think its very hot in my case, and the hot air has nowhere to go.

 

[stickg1]

What is the make and model of your case?

Basically you want cool air blowing in to the case with fans, then warm air being pushed out of the case with fans.
