Steve do you know about the Intel chip?

Click to expand...

the hidden turbo boost settings using the registry change work on both AMD and Intel CPU's

as of Intel software others maybe able to help better then me as i use AMD software
best of luck Steve ..

Just one small check, Idk detailedly the chip or the app:

- Which case and cooling are you using? I have a thermally similar old processor, an AMD FX-8350 (125W TDP), in a good enough case but with no good cpu cooler. It's an old full copper one that I was hoping to be better. It's one oriented towards the motherboard and I'm keeping it b/c my VRM is a bit forced with my processor consumption (I've also upgraded the cooler's fan and my exhaust fan is powerful as standard). The heatpipes don't have direct contact (likely the reason for its inefficiency). My main problem is that some webs overheat it "to infinite" (it throttles at 90ºC, it also gets hot with disk images compression and sometimes WU, but I don't consider these problematic, once WU had it one hour at 80ºC, when imaging it's only a few minutes if anything).

- In the times of my processor a TDP was "sacred" (in some cases, specially gfx cards, it was raised to allow more samples to meet the spec). Does this "turbo mode" comply with the 125W TDP? If not, is there any spec like [invented]RMP (real maximum power) 180W[/invented].

In short, consider a cooler upgrade. 125W isn't "extreme" but not anything will fit, if the real consumption is a lot higher you might need something special. As for the case, the bare minimum is an ample mid-tower with a powerful exhaust fan (unlikely to come with the case).

Steve guess what? After a few hours today looking at XTU, I finally was able to get into it as admin. It was a little crazy on how I did it, but xtu was talking about doing this or that in VBS. But I'm finally in. Now it's time to get down to busines about undervolting this bad ass chip. Where do I go from here?

JLArranz I didn't forget about you needing answers as well. My chip carries the 125 TDP as well. Currently when I stress the chip, I'm getting alot of Current throttled, which I will be looking into tonight and tomorrow about how to lower those. The type of case I have is a tall tower with lots of room inside. I love it compared with my other tower which is smaller.​

Do you know how I can get this CPU to behave like maybe only going up to 80c and cut down the power?
Thanks

Maximum Turbo Power: 253 W

(sorry to be late with this result, I was hoping someone more expert could interpret this for sure b/c I'm not 100% sure that you can send a task to your processor and get a steady 250W consumption)

If this is the "new TDP" with other name, you need a cooler that can dissipate 250W. Maybe you can disable "turbo modes" in the BIOS. Sorry that I don't know the names well. In one of my desktops with a Thuban (a very old AMD) I disabled it not for a thermal problem, but b/c the chip wasn't entering that mode steadily and doing useful things at the "turbo" frequency, b/c it's limited to 3 cores from the 6 the chip has, but Windows tends to use all the cores even if the CPU utilization is low. This processor's TDP is 95W and it consumes it or less either with the 6 cores at the normal frequency or with up to 3 at the turbo frequency (and the corresponding overvoltage; this is what I was meaning with "the TDP was sacred"). This cooler is good (unlike the one of my other post) and it wouldn't have problems with 125W, but with 250W I guess it's water or a "double cooler" like the Noctua NH-D15 (before buying anything, get the cooler's maximum power and get sure this is the problem).

If this is the problem and you get an air solution, you may need increasing the case airflow with more powerful fans.

I got to thinking, maybe this guy has something that I'm not thinking about and that are specs. So I looked up the Maxmum cooling capacity for the DH15 and found out that it can go up to 220W. Yikes, because according to XTU the max power of my chip is 253W. But with reading the P.S. on the bottom it can go up to 280W. Saved by the extra reading. So I was thinking (and I will research as well), how can I shave at least 30W of power off with undervolting?
Thanks
