X299 Specific Per Core Overclock

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have the Professional i9 XE and 7980XE. I want to overclock only two cores to 4.7GHz using Specific Per Core Overclocking mode, but it doesn?�t work. Clocks max out at only 3.899GHz according to HWINFO and all the synthetic scores are about the same as stock. My Asus Apex however did this flawlessly. Bug or I?�m doing something wrong?

	Bump. The multiplier seems to be hard capped at around 39 no matter if I input anything higher. The voltage offset works though. I can modify the voltage for each specific core. Is there any work around or does it require a BIOS update from Asrock to fix this?

	I have the same issue, the Turbo mode multiplier limits are not raised in Specific Per Core mode. This is a bug I think. I regret buying this board so far with my experience with all of the BIOS bugs.

	Yeah Asrock needs a BIOS update ASAP! It not just the Specific Per Core is bugged, the Per Core overclocking is also bugged. When using Per Core overclocking, it works flawlessly with up to only two cores. If you want to apply a custom multiplier to something like say 4 cores, it won't work because all 18 cores will run at that multiplier. I had 18 cores running at 4.7GHz even though I specifically set it to 4 cores, causing my CPU to overheat. Had to settle for 2 cores at 4.7GHz for now. Please Asrock, fix this! Per core overclocking is extremely important to high-core processors. It's more practical than All Core overclocking especially when AMD and Intel are bombarding the market with those.

	It's definitely a bug, but I figured out a workaround that seems to work for me on a 7820x. First, change the mode to Per Core, set the maximum ratios for each number of cores there (painful with 18 I am sure). I think you can just set them all higher than you want to actually go in Specific Per Core for now. This raises the multiplier limit per # of active cores, which is what was getting you stuck at 39. Once you set that, go back and change the mode to Specific Per Core without saving and exiting. Now you can set what you wanted. That worked for me anyway, you can confirm by looking at the limits displayed in Intel XTU. Sometimes the SpeedStep and SpeedShift settings cause issues and do weird things depending on their setting and sequence of the settings also. SpeedStep on, both Turbos on, and SpeedShift set to Native Mode no Legacy Support seems to work best for me. I'm running Windows 10 though, if you aren't I would probably disable SpeedShift. ASRock needs to fix the BIOS - the menus should not retain "state information" when you change the settings. That, or they need to make it so that when you set a Specific Per Core multiplier they remember to raise the Per Core limits to match the highest ratio you entered.

	Steps I've taken with the Per Core overclocking using a 7980XE with 2 cores disabled for now. 1) Reset CMOS 2) Set Core 0 to 46x; Core # = 2 3) Set Core 1 to 45x; Core # = 4 4) Set Core 2 to 42x; Core # = 8 5) Set Core 3 to 40x; Core # = 10 6) Set Core 4 to 39x; Core # = 12 7) Set Core 5 to 36x; Core # = 16 Intel XTU reports: It looks good on the Intel software, but in reality, the board runs 46x multiplier on all cores when it's supposed to do 36x if 16 cores are loaded. My Asus x299 Apex however does Per Core overclocking correctly. Edited by realist - 19 Dec 2017 at 2:42pm

	Hmm, yeah you're right, now it's being ignored for me also. BTW do you know how to find the mesh voltage if it's set to Auto? I can find the offset in HWMonitor, or the voltage itself if it's in override/fixed mode, but not the VID value.

	ASRock sent me a BIOS update when I requested an update to add the Multicore Enhancement option via support. This has fixed some of the issues at least, might work for you (v1.10).

	Same here, but worse... It's completly broken with the new 2 bios on January... Can't set core specific no more. It worked originally by setting the core specific values and then switch back to all core turbo and set the highest multi there (u may try with the oldest bios). Now it never works. Even per core OC can be set in bios but max push all cores to max or, it's lost on boot and my cpc runs with multi 26 max on all cores which sucks as slower than running it on stock.i can load my profile again but any now the board looses that setting from time to time. I regret buying that board already and I will request a replacement until it works, or my money back. I can expect a basic working functionality for that much money.

	It's disappointing to see this has yet to be addressed. I really do not want to go back to Asus :/ If this is working perfectly fine on MSI and Asus, no reason Asrock cannot have this done, and Asus even allowed for specific per core voltage I might add. I have two systems with X299 Taichi XE and I want this resolved otherwise they are both going back Pronto. Edited by TheL33t - 06 Mar 2018 at 10:58pm
