hwinfo, yes.

true, but "will simply report the last P-state known to the OS before the core entered a CC-state"

this leads me to believe that if I activate the AMD plan during idle, then the reported speed for the cores would change once the p state of a core is changed after that. but what I am seeing is all core frequencies being reported as full p0 right after I activate the AMD plan, all at once.

ed: damn. cpu package power actually does only show around 1-2W higher on the AMD plan.

Seems logical, but my voltages are still dropping as low as .384v so it IS doing something to lower those voltages. Can't do 3.9ghz at 1/3 a volt tongue.gif


It does that even on HP mode, hence the similar actual power usage.

mine's not. on the AMD plan, I'm almost 100% of the time seeing the full 1.4v...only for two measurement updates did I briefly see 0.850v. On the balanced plan, I am seeing around 1.0xx v most of the time.

also, only on balanced mode am I seeing wattages reported per core go down as low as 0.005W. on the AMD plan, all cores are always reported at at least 0.2-0.4W.

going by reported sensor values, the AMD plan is looking simply like the HP plan...

It will boot with 3200 set in Bios but only registers at 2400 in WIn10. I have tested this ram with 1 - 1700, 1 - 1800X and this is the 5th 1700X but the very first one that has given me problems under all default settings at 3200 w/ all the same components.

Yea for me it was my one and only 1700x that wouldnt boost at 3200mhz, did it once and once only after a cold boot nada. I can't complain considering it does 3.8ghz at 1.197-1.200v so beggars can't be choosers. I'm hoping a BIOS fix may fix it but not holding my breath. I tried the ram first at stock speeds and voltages and tweaked everything so i knew it wasnt the OC causing it not to hit 3200mhz.

You sticking with 3.8Ghz then Blue?

I just received some samsung b-die ram, as ryzen did not like my single rank SpecTek ram. I have it running at 3200 14-14-14-34 with the cpu at 4Ghz. The only problem is my aida memory latencies are horrible compared to pretty much every other post I have seen. When I first installed the ram I was seeing 78ns, which is in line with others, after a restart the latency went above 100, and I cannot lower it. It also lowered my Cinebench score 50 points. Does anyone have any idea?
post #8107 of 11563
similar story for me. 2933 ram? all fine and dandy. 3200 ram? lower scores across the board.

that's on a C6H. Since day 1 there have been rumors that the 3200 strap is ****y, and such reports keep me from trying to get 3200 divider stable. Ill wait for the agesa update with 3400+ straps.

I watched a video on youtube, was either jay2cents or one playing automatically after him with thousands of views... similar story.. scores were higher at 3000 than 3200.

I tried the 2933 strap, everything looked worse.

From the small testing ive done in balanced mode it will use 0-3 exclusively and not use 4-7 at all which leads me to believe that its using one CCX only but i have no idea how the cores are spread. 0-3 on one and 4-7 on another or odds and evens on one side and the other. No clue. Doesnt seem to be much difference between power modes they BOTH have downsides.

Balanced mode has latency if it transfers to the other ccx (more latency) and hp mode switches threads as it please (and again more latency probably even lag/stutter)

I may be jumping the gun, but I was pretty much JUST testing this exact idea/setup. My test suite involves power plans, core parking, downcore control to examine CCX performance (2+2 and 4+0), and how they all relate to combined score in firestrike.

While I haven't checked all my results and graphed them just yet, will be making a thread later tonight/tomorrow, it doesn't seem that the CCX complex/implementation causes any performance impact. What does seem to be an issue with 3DMark firestrike and the combined test is having more than 8 threads (AMD CPU quirk?) and how windows deals with core parking.

**I'm suspect of 3DMark being the culprit in this regard. No other benchmarks seem to exhibit this behavior; I wouldn't be surprised if some of the recent Tomb Raider benchmarks could be related to the same issue though.
