Over clocking for stability rather than speed.

[computergeekguy]

Hi, recently I posted problemm concerning BSOD's. Arc was able to help me narrow the problem down to my CPU (AMD Phenom II 1055T) however some things are not making sense. I am just curious if some tools used by overclockers might stable out my cpu a bit. (You can find all the info about my rig in the specs column.)

When I run Prime 95 my CPU stays at 41c and dosn't get any hotter however all 6 cores stop with errors in around 15 minutes.

I don't much care to overclock the speed as my CPU has mostly handled all tasks fast enough for my liking. Except for those BSOD's!

When an overclocker learns his clock is unstable he usually:

1.) Increases the Voltage.

2.) Backs his speed back down to where it is stable.

Do you guys think that increasing the voltage might help anything? Also if I increase the voltage and leave the speed alone will I need to also change the speed of my ram and such?
Lastly, does anyone happen to know my CPU's max safe voltage?

Thanks.

P.S. What the heck is advanced clock calibration?

Possibly 55C, I have 1090T they are not much different as far as I know.

Increasing CPU voltage alone won't affect anything else. Check some overclock forums for 1055T if you try that though.
Tried downclocking the CPU yet? For example in power options (control panel) go into advanced options and change max processor state to 90-80% etc
Or tried disabling Turbo, Cool&Quiet?

Hi,
Any overclock you'd be increasing both cpu and dram frequency nearly at the same rate ram possibly a little less on dram say 5%
I've done some preprogramed overclocking using my asus mother boards features that's about all
19% cpu and 14% dram seemed fine
The rest was using gpu tweak for oc'ing the gpu and that varied depending on the benchmark test all of them react differently to the same settings so almost everyone needed it's own profile :/

I've haven't heard anything good about prime 95 though.

I use Prime95 to test CPU if need be, but there is also Intel Burn Test many use.

Hi, I used Intel Test Burn and it says my system is stable. Prime 95 said I was stable for an hour until 1 of the cores goofed on small FFT. I am thinking if it is not a problem with the CPU or the RAM then it must be a problem with them being used together. For some reason they fight each other in my opinion.
Also I looked for the "max processor state" option and for some reason my desktop doesn't have it. I would have to downclock via bios. In that case I think I would just drop the multiplier down to 12x or something.

Edit: I tried turing of Cool and Quite and turbo core technology. Prime 95 still gave me an error. Also I set the multiplier to stay at 14x and not change to see if that would help. It didn't.
Thanks for the responses though.

Be sure and watch your temps.
A tenth or two raising volts can raise temps quickly.

Prime95 dropping out after 15 minutes or so may not be a CPU problem at all. You might have a bad stick of RAM.

Have you tested your RAM with Memtest86+? A minimum of 8 passes overnight will tell you if you have a RAM problem.

Here is an older description, but the concept is the same:

ECS - Motherboard, VGA, Notebook, Tablet PC, System, IPC, LIVA

Lastly, does anyone happen to know my CPU's max safe voltage?

There are two different models of your processor. One is 125 Watts TDP, and the other is 95 Watts TDP. Which one do you have? The voltages are different depending on the model.

Here are the details for both:

AMD Phenom II X6 1055T - HDT55TFBK6DGR / HDT55TFBGRBOX

AMD Phenom II X6 1055T - HDT55TWFK6DGR / HDT55TWFGRBOX

Max Processor State doesn't show up when Cool&Quiet (or IEST for Intel) is disabled. But sometimes you need to click 5 - B in http://www.sevenforums.com/tutorials/778-power-plan-settings-change.html. But since it didn't change anything, don't bother.

Did you test the RAM as advised yet?

 

[computergeekguy]

Yes I tested the ram for 11 passes. No errors. I also tried playing with the configuration of my ram sticks to no avail. My CPU is the 125 watt version.
Thanks

Your max VCore is 1.475 Volts. I don't suggest you go that high without good liquid cooling.
