What controls Turbo Core in Xeons?

280mm size / 360mm size liquid coolers will be sufficient and quiet too. But it doesn't make sense to invest money in this rig right now, when better cpus like threadrippers are available.

What controls Turbo Core in Xeons?

I'm using two Corsair H45s on dual E5 2686v3. But I'm not using with stock fans, i using two 3400rpm nidec servo high static pressure fans in push pull, but this setup is noisy, but work fine at cheaper cost.

What controls Turbo Core in Xeons?

I tried this mod with MW70-3S0 with dual 2686v3 in october this year. (I hav dual 2686v3 not 2696v3) For some reason this rig was freezing with u-code 27 under cinebench load, it only worked stable with u-code 39 and 40, but max all core turbo was x26 under heavy load. -70, -50, -20 was...

For dual 2696v3, you will need minimum 750 watts gold rated PSU. Gigabyte MW70-3S0 has weaker VRM than Asus, though you can use this turbo mod but at lower intensity (lower performance boost).

Thats good, you should post benchmark results after testing it

If this turbo mod is working for you, then I'm sure your CPU is drawing more than 120w, you should confirm it with watt-meter. I think Huananzhi board doesn't have option to change bclk, it is same as any other server motherboard with no overclocking features (i maybe wrong as i haven't used...

When i was using this mod on Gigabyte X99 Gaming 5p, i had to set CPU TDP limit to 4095 in BIOS. I didn't had to do such on my asus Z10PED16-WS. Also try to set uncore ratio to lowest, this will increase your multiplier. Also in many softwares like HWinfo / core temp you'll see CPU TDP never...

Did you check my post #2599, #2660, #2804, TDP is already bypassed.

I don't know about any bug fixes, but for my dual 2686v3, u-code 39 gives max multiplier of x26 under heavy all core load. With u-code 27, i get max multiplier of x31 under heavy all core load. 120w TDP is already bypassed, without this mod, CPU only load power consumption was under 350watts...

You should use u-code 27 for best performance.

Did you enable C3 and disable C6 in BIOS ? Without this i faced bootloops, crash at startup and all. No u-code gives you higher in AVX2 load like corona / CB R20. This is useful if you use rig for rendering purpose. I get ~5300CB in CB R15 with this, you can check my previous benchmark post...

It seems bclk OC depends on silicon lottery. I'm using QS version of 2686v3. What u-code you're using ? Try u-code 27, it will make your CPU always run at x38 with only 10 cores with HT enabled, but this results in higher idle power consumption. You can also try it without any u-code, it should...

U should get x38 on 10 cores with HT enabled. How much undervolt you're using ? I'm running my rig at 105mhz BCLK from last 8 months, only faced 2-3 random crashes till now.

I'm not sure if it will work on Ubuntu 18.04 or not, but it will work in windows 10 v1804 and later. Check my previous posts, i have done this mod with dual 2686v3 on Z10PED16-WS. I got stable 3.25Ghz (x31*105mhz) on all 36 cores 72 threads. If only 20 cores enabled, then speed was fixed at...
