Or do I have correct numbers and yours are incorrect tongue.gif

Benchmark results seem to lean that way, but who knows.

Does it actually hurt bandwidth though?

Numbers are based on CyberPower Pure Sine power supply.
By subtraction between power drawn during 1-core benchmark and 8-core benchmark I get 14W/core at 4000 and 15W/core at 4100.

And no, that 1.5V is not safe. Don't try this at home.

Theoretical maximum memory bandwidth for 2666 speed:

( (2666*2)*64 / 8 ) / 1024 = 41.65625 Gbyte/s

for 2933

( (2933*2)*64 / 8 ) / 1024 = 45.828125 Gbyte/s

This is what I got with 1.60 bios



This with 2.0 bios




And this is with the same cpu speed of 4025MHz with 1.60 bios

All but one of your cache scores went up and 12/16 of the scores went up/stayed equal. Would be interesting to see, assuming the numbers are correct, which performed better. I'd assume 2.0.


Either way, your 2933 =/= my 2933.

Cache bandwidth is dependant on cpu speed, 1.60 capture is 4000MHz core speed and 2.0 capture is 4025 tongue.gif

Not sure why.

Not sure why.

Because I did this test and I am sure your memory bandwidth would improve with 1.60/1.70 bios, but anyway I've heard new bios with microcode 1004a are on their way so maybe not worth reverting back (just for testing)

Well, my test at 4.0ghz on 2.0 with 2933 is still short of yours. That's what I meant.

BIOS. After LLC (set at High), VCore (ITE sensor) displays it around the ballpark of what I set in the BIOS with +0.025V IDLE spikes. Under load, Droop affects it to a lower Value like -0.050V.

IOR (Mosfets) sensor and CPU VCore are within 0.005V apart depending on Load. But stays within BIOS Value at IDLE.

In numbers, 1.300 in BIOS will be:
IDLE
ITE VCore - 1.325 max
CPU VCore - 1.300 max
IOR VR OUT - 1.297 max

LOAD (IBT)
ITE VCore - 1.275 low, 1.288 average
CPU VCore - 1.225 low, 1.237 average
IOR VR OUT1 - 1.220 low, 1.225 average

Starting at a point that fails to boot (lower voltages vs safe, higher voltages) seems rather counterproductive to me (not to mention frustrating). In the end, our processes are our own and most have a different method to their madness; if it works, it works.

Haha. Don't confuse Ryzen with any other CPUs you have had.

Keep your eyes open for reboots rather than errors even if you are just lacking 0.025V on the Core.

Again, the issue with these chips is the terrific loss of efficiency after a certain Clock to Voltage curve. Past that efficient curve, your issue grows bigger.

Tell you what. First boot of the system, I simply put 40 Multiplier, 1.3 VCore. Boots fine. Installed Windows just fine, ran benchmarks perfectly fine.

Loaded X264 encode, baam! Black screen. Okay, add VCore. 3-days of dillema on the issue. Only to find out that 4.0 needs 1.425 to keep it from shutting down with real world loads.

If you are just gaming, your process may work just fine. I'll leave it at that.
