In the beginning, they all stick solid at the speeds and voltage assigned to each core. It behaves the same and appears to only happen as temps elevate. I did more testing this weekend and regardless of vcore, LLC, etc. Lastly, if the CPU is sticking to 4.8 Ghz in everything but stress testing, is that even an issue? I assume buying a higher end MOBO just to eliminate the VRM throttling won't do anything for me in terms of performance 99.9% of the time, as I have only seen it drop under the Prime or IBT loading.Īppreciate the thoughts, help and suggestions! Is VRM the culprit here for the throttling? Or is there a setting in the BIOS I am missing? (I disabled thermal throttling and other options I thought may be doing it). Using HWmonitor playing the games I do, it never throttles at all under the typical demands the CPU sees looking at the min/max. Only under Intel Burn or Prime95 does it do so after a little while (I assume when heat builds up). Otherwise in games, the voltage/frequency is solid at 4.8 Ghz and doesn't move at all. So does the VRM throttling sound right? Is there any way to get around this (or loosen the max temp) for this MOBO? I would have went for a higher end MOBO had I known this limitation, but I am not sure it's worth the hassle of buying a new MOBO and swapping just to allow for no VRM throttling when stress testing only.
CPU THROTTLING INTEL BURN TEST UPDATE
I did update the BIOS to the latest version just the other day from the MSI website for the board, so it's running the latest. It usually begins after a few minutes or later (more demanding?) iterations kick in.Īfter some research and playing around in the MOBO, it appears to be the MOBO VRM protection or whatever is kicking in? Perhaps getting too hot. Note, it doesn't throttle immediately for stress testing. I disabled all the thermal monitor / throttle options in the MOBO that I could find (or so I thought)? Because as I have read, this chip really shouldn?t *thermally* throttle until around 90C, correct? My goal is to not push my OC?ing beyond about 75C when stress testing, but the throttle to the voltage/frequency is making it difficult to see what the temp is really doing when at the limits. So it sounds like at 65-70C there is some protection coming in from somewhere that I can?t locate. When it starts a second iteration of fft in Prime95 starts, the temp rises in the ballpark of 65-70C instantly and then the voltage and frequency drop? So instead of 4.8 Ghz it will go to 3.8 Ghz to 4.4 Ghz? And the voltage will lower as well.
CPU THROTTLING INTEL BURN TEST FULL
Under full load it tends to be around 55-65C for the most part running Prime95 and doing the fft test. So I am currently at a 4.8 GHz at 1.275V (LLC of 5) and it has been rock-stable so far. If anything I just wish this one had 8 SATA ports vs.
This board had solid reviews and I figured I didn't need some of the features on high end boards (wireless for example, more PCI-E slots, ports, etc.). To be honest, I am probably the least knowledgable with MOBO's and their features and capabilities, so I directly went off reviews I could find for the Z370 MOBO's when selecting my components. Just built a new computer with the following:Ĩ700K (equipped with Noctua NH-D15 cooler)
