CPU performance issues on Dell workstations.
CPU performance issues on Dell workstations.
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.
No, your Windows power plan is not currently set to High Performance.
The installation is brand new. No Dell software has been applied. Even the pending updates remain uninstalled. With the power limiter, I attempted to check every section of the BIOS but didn’t locate anything. I’m not entirely sure if this can be resolved through the BIOS settings.
I visited the Dell support page but they couldn't assist me since they stated the system was no longer covered under warranty. The CPU I have is different from what came with the machine, and I recently upgraded it. I don't recall the previous model, but I believe no Xeon E5 1600 CPU reaches around 70W.
Indicates compatibility with up to 14 E5 2600 and 1600 v3 modules... yet 14 cores seem excessive compared to my setup. Also, supporting 1650-1680 v3 offers identical bus speed, and honestly my chip isn't reaching the performance of its earlier version.
Changed BIOS from A28 to A34. Reviewed BIOS settings but no extra options detected. Performance remains consistent at 3591.8MHz and 72W. Rating still below i7 3730K.
