I had this stable at these clocks with an aida test of over an hour with 9943. on that note me thinks it has more to do with the removed offset then anything else cause the test before it said my cpu overheated even though this benched with a high of 78 with the offset after that hour

Had the exact same issue even at stock. AIDA does not like this BIOS. I then went on to pass 6000% on HCI with 3466CL14.

CPU throttling starts at 75°C and hard shutdown at 95°C. The X model 20° offset isn't part of this, that pretty much only affects the fan speed profiles. If you are overclock without using p-states the throttling behavior will be disabled.

Where did you get that information from? i'm not sure that's correct. Some people posting on here have reached 78ish temps with no throttle, can anyone confirm this info?

Just wondering but is around 1.4375-1.444v safe in idle/low current load?
I'm using LLC Auto so stresstesting voltage is around 1.369v

Latency: from 78 to 84 according to the setup.

hwmonitor is showing some pretty weird idle temps same as bios) and load temps with all default + clock 3.6ghz and voltage 1.35v... idle temp at 18c and prime95 load temps 35c with stock cooler, could it crash because of overheating even though no throttling occurs?

So @the stilt's 3466 timings are not stable for me. Do you know which settings I should increase to make it stable? Or should I stick with only the primary settings of 14-14-14-14-34 and leave everything else at default.

spectre a well known member says that's incorrect throttling starts at 95 shutdown at 115C he runs the 1700 at 1.5v and he's hitting 90+ stress with no throttle till 96

Half of the 3DMark Sky Diver Combined Test score comes from the physics score. The physics engine used in 3DMark is Bullet, which is extremely sensitive to latency.

3200MHz 14-14-14-75-350ns-BGSE = 116.85fps
3200MHz 14-14-14-75-350ns-BGSD = 119.51fps
3520MHz 14-14-14-56-177ns-BGSD = 125.07fps
3200MHz 12-12-12-54-140ns-BGSD = 127.07fps

These are with R7 clocked at 3.575GHz.

Those are five run averages, since the score varies slightly between the runs.
3DMark SD CT isn't the best benchmark to evaluate the real world memory performance, however it is quite decent and can be run very quickly.

I can no longer get them stable either on the new PMU used in 1401 bios.
xSC and xSCL timings need to be raised significanly to stabilize it on the new PMU.
Useless, like I already said as these timings are pretty much the most critical ones for the performance.

Could you head over here and give me your pstate 0 idle and heavy load (bench) cpu core and core voltages?

Much appreciated! You even get an imaginary cookie! biggrin.gif

Vdroop is normal and you'll need to use LLC to account for it. LLC3 should be fine on your HW. 4-5 comes down to your courage I suppose.
