And then Definately a 12c chip would be right up my alley, whichever one can offer the best balance of Performance across say 8 cores, and still good single threaded.

Imagine stacking 2 1800Xs into a single chip with TDP and Power Limitations. So don't expect them to hit 1800X clocks.

8C/16T will not be offered on that platform - hint, Quad-Channel memory.

I think everybody should post their results in gupsterg's thread so he can add it to the Ryzen data sheet so that newcomers considering Ryzen have some hard data to base their purchasing decisions on and OCers can get a ballpark idea of what they can expect.

@gupsterg

Might be handy to add a cell for benchmark scores too that people can fill out just so people have a way of comparing IPC to other CPU µarchs...even if it's just a cinebench multithread score.

But I also game every now and then, and photo editing.

My first issue with Ryzen is that at stock, it doesn't even beat my 4yo CPU @ 4.0 on things like game
On pro things, it beats my current CPU, but vs a 6900 @ stock , if you exclude video encoding it is not that great (-30% on Winrar,-10% on compiling, etc), and the 6900K can trivialy get to 4.0, where it is also an improvement over my old CPU)

Hence my question on OC, but if the ceiling is 4.0 that is probably not going to be good enough
I might also wait this summer to see the new platform that will replace X99, but then I would run in the same teething problems a the new AMD platform
On pure multithreaded yes, but I want a good balance with IPC, that Ryzen doesn't provide at stock

Memory speeds improving with microcode should improve every metric affected. Including gaming. But quad channel cannot magically appear on existing motherboards. Nor will additional pcie lanes for additional gpu's. x8 x8 might not be a handicap, I'd wait a bit to see how the microcode improves things.

It could be easily offered as a 2+2+2+2 configuration o-o with just cores disabled, again steppings. I don't know they might do 1800's? I don't know AMD's intention with the 1800x to be honest, the high leakage does allow it to XFR to 4.1 safely. Boosting voltage to like 1.5-1.55 and hitting those 4.1 ghz's Thats only thing I can see as a advantage else, 1700 is basically better as a economy processor in every way specially when talking about jamming 2 in the same chip

DMM still shows 1.268 BUT hwinfo64 shows VDDCR_CPU at an average of 1.200v so not sure which one to believe at this point. If hwinfo64 is correct I'm doing 3.8ghz at 1.2v fully stable. My offset is set to -.100mv i believe (id have to go back to double check but pretty sure thats where i left it could be wrong though)

Tctl only reach 48°C (the cpu temp sensor was stuck at 40°C) and water temp was 30°C throughout the whole test. I have a 360 in push/pull and a 240 in push with all fans around 1100rpm (quiet noctuas).

Would love to try for 4.0ghz but right now i have no idea which voltage to believe in haha.

Pretty happy with it so far though seems to be well below what some people are seeing. I did notice that playing Rust balanced mode works much better as it only uses half the ccx, the other half pretty much just sits at 0%.

Nice smile.gif .

Below screenie, pretty much steady ~1.35V on Pro Belt for DMM. As explained by Elmor the Pro Belt is showing a value inc of LLC (ie VRM output to "power plane"), measuring at socket would show VDROOP.





My G.Skill RAM not back from RMA yet, I tried to OC the Corsair 2400MHz C14 to 2666MHz, but had sporadic errors at differing times in HCI Memtest, dropping CL to 16 didn't help nor upping RAM/SOC voltages. So as I ordered another CPU coming for Tuesday I thought I'd get some more profiling done on the chip. So here are my past 3.7GHz results:-

Warning: Spoiler! (Click to show)
At that time no offset added RB 60min pass



At that time no offset added RB 120min pass



At that time no offset added x264 1st loop fail



At that time +12.5mV offset, no DMM readings at the time, added x264 3rd loop fail



At that time +18.75mV offset, DMM: ~1.228V, x264 pass 10 loop



So today I try +18.75mV offset for 3.7GHz.

Warning: Spoiler! (Click to show)



+37.5mV.

Warning: Spoiler! (Click to show)


+50mV.

Warning: Spoiler! (Click to show)


So to sum on the 12/03/17 I pass 60min RB, then 120min RB with +0mV, this fail in loop 1 of x264. What I needed to pass 10 loops on the 12/03/17 (+18.75mV) fail 1st loop x264 on the 26/03/17 and it took a jump of +50mV to match stability as my 3.8GHz OC. I'm approx. at DMM: ~1.26V for rock solid 3.7GHz and DMM: ~1.35V for 3.8GHz.

Alright so should i go by my DMM at the measure points or by hwinfo64 showing me 1.200v for sddc vcore?

My opinion go with the Pro Belt reading, that's showing you the highest level of VCORE the CPU will get, as that includes LLC from VRM. So for me I wanna know the highest value.

My 24/7 OC MHz ceiling limit is what I can attain with close to ~1.35V MAX.

Even at LLC: [Auto] there is LLC active, it's just at AMD specification wink.gif .

The VRM sense circuit would need to be reported and I don't think this value is available for monitoring.

What about what Elmor said?

The VRM uses on-die sense outputs to read accurate voltage at the "destination". It will thus output a higher voltage during load because there will be significant voltage drop across the CPU and ground power plane. To get a more accurate reading you need to measure at the MLCCs at the back of the CPU socket, and be sure to also get your ground point from there.
