Hi there! Hope you all are doing well! I have a Dell Precision Workstation 5810 with an Intel Xeon E5-1650 V4. The problem is that CPU draws only 72W from the wall as per Open Hardware Monitor under full load in Cinebench R15 (I know its the old one 😕 but I have tried R23 as well and it is not performing as it should). The CPU doesn't turbo pass its base clock speed i.e, 3.6GHz when its expected to draw 140W and clock somewhere near 4Ghz (I know it won't do full 4ghz at all cores) resulting in slower performance. And by slower I don't mean the system is slow or anything but in Benchmarks it performs similar to a 3rd Gen i7 3960X which is ridiculous for a Xeon 1650 V4. I have enabled Intel Turbo-Boost and Hyper-threading Technology in BIOS, checked the temps and they are under control even with low fan speeds but I really tried 100% CPU speed and really made it a server like noisy machine. But no help. It just straight up doesn't go above 3591Mhz and draws 72.6-73W at max under full load. I want to waive off this power limiter set from dell. I don't care the means even if there is no simple tweak present to do this. For additional info my PSU is also 685W Gold so its not the 480W some thing small one. Looking for someone to help me with this. Thanks in Advance, Regards.

Dell Workstation CPU Not Turboing!

Here is a person with an E5-1650 v4 that scored 1212 in Cinebench R15.

It looks like he is using a lean version of Windows 7 with only the bare minimum of benchmark related apps installed. He probably does not have a GPU driver installed yet. People using HWBot tend to be serious overclockers that know how to get the most out of their hardware. There are lots of tricks like this available. Running Cinebench at Windows Realtime priority is a popular trick. Disabling some C states might be good for a few more Cinebench points. He is using Quad channel memory. His CPU-Z results show the timings and speed that his memory is running at. How does your memory compare? Are you using Dual Channel memory? Your Cinebench results are not a long ways away from one of the world's fastest E5-1650 v4 on HWBot.

however it is jumping up and high all the time

Background tasks that randomly spike CPU usage are the main reason why your CPU is not scoring better. That and the memory you are using.

Here is an example of my computer when it is idle with only Google Chrome open. Run a similar test on your computer with only ThrottleStop open. Your average C0% is much higher. Those wasted CPU cycles are the difference in performance.

An E5-1650 v4 at default settings will always be faster than an E5-1650 v3 at the same default settings when everything else, including memory, is equal. It is impossible to make a fair comparison when the background tasks are not the same.

An E5-1650 v4 is 4th Gen Broadwell technology. No point in making any comparisons to an 8th Gen 8700.

Great to hear this
