Cpu current throttle limiting

[frankr2994]

So just got done putting together a Dell T5810. I swapped the cpu for an e5-1650 v3. I also swapped the 425 watt PSU for the 685. Only thing really drawing power is a gtx1650 super. But I was all done and not interested in overclock but I lit up xtu and it had a yellow warning for current/edp throttle limiting. What it's doing is 2 core turbo is at 38x and 3 through 6 is at 36x. This is supposed to be all core 38x. Running stress test show it's not getting hot and tdp never going above 90... What can the problem be?

update your bios if you haven't

Most Xeon CPUs installed in Dell computers do not support the all core turbo feature.

 

Can you use XTU to increase the current limit?

Bios is A32 which is the latest and also crazy that there are that many revisions. I'll give it a shot increasing currents with xtu but I've never seen those settings stick on dells. Always pretty locked down. Xtu , cpuz and throttle stop claim it's an unlocked cpu I just can't do anything with this motherboard. One thing I can add is after swapping to this cpu which draws alot more than the 2640 that was in it I ran Dell preboot diagnostics. Everything passed but I seen that cpu temp went into the 80s. That's too hot for this cpu anyways according to Intel. I guess the precision lineup has an issue with the auto fan control. I ended up setting the minimum auto fan control to 25 percent and now nothing even thinks about getting hot. There are no thermal events logged that I can see but is there a possibility there is something in there from that first stress test that has that triggered that and would require a cmos reset? It will be a couple hours before I can try anything. Gotta watch the kiddos while the wife is working.

Ok xtu settings don't stick...any of them so in windows 10 power plan if I pull max cpu usage down to 99 percent the current limit warning goes away. Restart still shows turbo multiplier at 36 and xtu on its own shows proposed at 38x this may be a Dell thing but very disappointing since this cpu has a very small turbo. I may try throttle stop one more time because it did let me set it at 38 but I still had a warning in xtu and maybe that prevented it from working.....

Ok it's the voltage settings. Intel claims up to 1.30 volts. If I use throttle stop and keep it set at adaptive but raise max to 1.20 I can all core turbo this to 4.2. now temps start getting high but 4.0 seems reasonable. With the voltage ceiling raised I get no throttle faults. I'm guessing with a real good cpu cooler you can overclock the hell out of this thing. But right now 4.0 6 core turbo for 92 bucks seems awesome.

I know I'm talking to myself now lol but I'm back to square 1. I restarted the system and everything reverted back. I no longer have the option to over clock using throttle stop. I did a system restore and tried it and now all my options are locked out and just bumping the voltage seems to do nothing.
