Trouble Overclocking G3258

[lcater95]

Frequency: 4.3GHz

Voltage: 1.21v

Max temp: 63C

 

This ok?

If your bios is not working correctly then yes, you will need to run ThrottleStop every time you boot up to setup your overclock.  Once you have fully tested your CPU and come up with some stable voltage and multiplier settings, you can add ThrottleStop to your Start Up sequence using the Windows Task Scheduler.  I wrote a nice guide but unfortunately all of the pictures disappeared because I didn't want to give any money to ImageShack.

I uploaded some pictures of what the Task Scheduler should look like in Windows 8.  Hopefully you can figure this all out.

Make sure your CPU is 100% stable before adding this to the Task Scheduler.  If your overclock is too aggressive and your CPU is not stable, you can get into an endless BSOD loop when trying to boot up.  I like running Prime95 to test for stability.

 

Your Max Temp of 63C at 4.3 GHz sounds a little low.  What sort of load were you running?  Prime95 will likely push your CPU much harder than that.

 

Post some ThrottleStop pics while load testing your CPU.  It's a very accurate monitoring app with overclocking and voltage adjustment features for the 4th Gen CPUs but desktop users hardly ever use it.  It is a popular app in the laptop community for a reason.  It can get the job done when the bios doesn't want to cooperate.  

 

ThrottleStop also has an INI option called ExitTime.  When ThrottleStop starts up, it will set up your CPU and then it will quietly exit so you can forget about this problem.

 

ExitTime=5

 

would exit 5 seconds after setting up your CPU.  

 

I have never run ThrottleStop on a desktop 4th Gen CPU so any feedback is appreciated.  You might need to adjust your turbo power limits higher depending on what the bios set them to.

When booting up and only running Intel XTU, can you get your CPU up to 4500 MHz or do you first need to use ThrottleStop to unlock Turbo Boost?  I plan to add an adjustable cache multiplier to ThrottleStop sometime in the future as well as some more CPU voltage adjustment features.  You could probably bump your cache up from 32 X to about 40 X without losing any stability.  When overclocking, many people lose stability if they try to run their cache at the same multiplier (45 X) as the CPU core is running at.

 

Everything is looking good though.  Thanks for the feedback.  At 48.9W, you are running under the 53W TDP so your CPU is having no problem maintaining full Turbo Boost when fully loaded.  Make sure to also try the Prime 95 - Small FFT test.  To maintain 4500 MHz during this test, you might need to increase your turbo power limits.  If you see the ThrottleStop multiplier starting to drop a little when fully loaded, that's usually a sign of turbo throttling due to reaching the turbo power limit.  The ThrottleStop reported multiplier is a very precise view when turbo throttling starts to kick in.  Now I want one of these little $70 beasts.

I was only using XTU for monitoring. When it comes to temperatures am I safe? What is the max temp I should safely run at?

You should definitely pick one of these chips up. Best $75 I've spent in a while.

Your CPU core temps are fantastic.  When stress testing 4th Gen CPUs with Prime 95, temperatures 20C to 25C higher are not unusual.

 

Intel says the "maximum safe operating temperature" is when the processor hot (PROCHOT) signal goes active.  That does not happen until 100C for the G3258 so you are a long ways away from having to worry about that.

80-85c. to overclock in the gigabyte bios, all i do is set the core voltage to 1.2v, then everything to manual. set xmp speed, timings and voltage in the ram section. then the bclk frequency to 100.02mhz. then the multiplier to 40x and slowly increase the multiplier stress testing inbetween each 2x increase up to 4.4ghz the every 1x increase after that. the turbo is left on auto, i also set the load line calibration to extreme and turn off all the power saving features. that last bit is optional.   

 

you also want to keep your uncore as close to your cpu frequency as you can as well. try 40x on that. you might need a bit more voltage and the one that you increase to stabilise it is the voltage that is 1.8v @stock in the bios and you can go upto 2.1-2.2v with that.

Thats awesome! I feel like it may be worth getting a AIO or bigger heatsink than the 212+ just to push the thing to the limits.

In the Intel Turbo Boost Technology section of your bios there is a problem.  You have this set to AUTO and then for the Turbo Ratio you are requesting 43 - 43 but it looks like you are only getting 32 - 32.  This setting is what controls the maximum speed of your CPU.  Instead of the AUTO setting for Turbo Boost, try using an Enable or On setting if that is available.  The 2 little values that are showing 32 need to show the full 43 turbo boost multiplier.

 

A lot of users do not understand how Intel CPUs work because some motherboard manufacturers provide bios options that are misleading.  The default maximum multiplier for a Pentium G3258 is 32.  To go beyond this value, Intel Turbo Boost must be enabled within the processor.  Some motherboards trick users.  They provide you with multiplier adjustment options and then quietly in the background, depending on what multiplier you choose, they decide whether Turbo Boost needs to be enabled or not.  In your case, to access the 43 multiplier, Turbo Boost definitely needs to be enabled within the processor.

 

I wrote a program called ThrottleStop that lets you make sure your CPU is being set up correctly and it can correct these sort of problems when it is not setup correctly.  The latest version 7 is still in beta but it has the necessary features to make sure your CPU can run at its full rated speed.  If has been out for a couple of months without any issues.  You can download version 7 from here.

The TRL button gives you access to the Turbo Ratio Limits as well as CPU core voltage adjustment.

Version 6 Final is also available from TechPowerUp.  This is a popular program with laptop owners but it also works on Intel's 4th Generation desktop CPUs.

 

If you need any more help, my email address is in the About box of ThrottleStop which can be found by right mouse clicking on the system tray icon.

 

I figured out how to OC in the bios thanks to everyone's help. I left everything the same in the bios as my previous tries but this time I upped the uncore multiplier to 40x. By doing this it applied all my OC settings. I'm going to try to go for a pretty agressive overclock like 4.6 or 4.7 maybe since I have about 10c of headroom.

 

Thanks guys.

good make sure you post the results so we can see how high you get.

4.3GHz and 4.6GGHz with adaptive core voltage up to 1.173v on 100% load with LinX

on 4.7GHz I get an instant bluescreen with 1.173v :>
