Shorten operation and pause modes
Shorten operation and pause modes
You're using a Dell T5810 with an unlocked E5-1650 v3 CPU. Overclocking works well with throttle stop, but you need to power on the PC and briefly wake it before unlocking the multiplier. Sometimes Intel XTU can fully unlock it, which is great. After a restart everything resets, so you have to wake again. Since it's an OEM board, I'm not sure what the best way is to ensure overclock remains active during Windows boot. You're open to modifying the BIOS, even changing it if needed.
Show some screenshots of your ThrottleStop configuration. Display the main screen and the FIVR and TPL interfaces. Be mindful of potential conflicts when using ThrottleStop with Intel XTU together. Mixing different programs writing varied data to the same CPU registers can lead to setup inconsistencies. Some Dell workstations restrict certain registers during boot, requiring a sleep resume cycle to unlock them. This method exploits a BIOS bug that overlooks the lock bit during resume, which may be the cause. On OEM boards with limited BIOS settings, this issue is often unavoidable.
I'll share some photos tonight when I'm back home. If your advice about the sleep resume is correct, I guess I'll just have to accept it. I've only tried ts or xtu separately so far. I'm always interested in seeing if xtu can perform tasks on an OEM board. This is the first time I've actually unlocked it, but it didn't last long. Rebooting showed me it wasn't possible to use a sleep resume for unlocking, while ts did work.
You noticed earlier that some settings were altered and couldn't be applied. After a sleep/wake cycle, you could reset all configurations. But the maximum turbo boost for all cores remained locked at 3.8, which is the default for that chip. After restarting ThrottleStop, you're unable to apply any overclock you wish.
I realized now that I’m able to adjust it. While testing various clock speeds, I had to verify the multiplier box to make changes work. Once I unchecked it, everything functioned properly. I’m satisfied with the outcome. After getting the steps right, putting it to sleep at startup feels fine. When I find a stable clock setting, I’ll save that profile. Your software is really impressive and has transformed this Dell workstation into a powerful machine. Now I just need to check if I can adjust the CPU fan speed for this model—it doesn’t increase until around 81°C, and it still isn’t at full speed.
Hi Frank, your t5810 is turning off properly at night, but it doesn’t display video when you try to wake it. The keyboard lights up briefly before shutting down again. I’ve shared more information about this problem in a private message to your profile on the Dell forums.
