1.025 for this cpu. other cpu prefers different and can post/boot with 1.3 hits EC at 10400 c5 10600 so will do 10400 cold likely but it's fclk challenged so using this one.

HDV on the way for M die testing. See if i can't figure out how to port what i find to gigabytes so they cooperate with M on 8700g

Is SOC voltage OK that high on that chip ? 1.38 seems a bit high, unless they changed it, I thought it was limited to 1.30v max ?

your CPU boost speed is too low. Try an agressive curve optimizer and rerun, add some bclk to the mix for even better per core performance.

What do you mean by that? Like my CPU doesn't boost as it supposed to? From other peoples screenshots it looks the same. I currently have an undervolt in curve optimizer, does it hurt my performance then?

Use a hair dryer and a plastic sludger, they come off easy, do the side without the chips first, the plastic spludger wont damage anything then, and then the side with the chips comes off very easy once youve done the back.

Yup, this. The TEAMGROUP back end on SR is pretty well stuck down but a hairdryer and some patience with a spludger moving along and focusing evenly and it is fine.

A guitar pick would probably work as well. Something plastic that has a little give in it. Don't use cutlery/screwdrivers/anything metal that might damage.

Still ticking away testing CL26. Wanted to see if 1.65v changed temps much, not really. Pretty much the same as 1.6v.

If this is stable I guess I could daily it! Not much more meat to pick on the bone here, maybe see if the SCLs will do 5. Then probably seeing what voltages might reduce to. And finally, benchmarking and making sure no performance regressions at 2200 FCLK and/or from any memory timings being too tight/non-optimal.

Still searching for a way to turn off the RAM RGB as well lol, I guess it may also reduce power draw. I simply refuse to install ASUS Armory Crate to handle RGB, it is one of the worst pieces of software in the history of software.

openrgb can turn it off, as said above, but I don't think it can do so permanently, without the program launched at win logon.

some ideas for you to explore:
you might want to check if your CPU can do 6600 MT/s
otherwise check performance of 6400:2133 vs 6400:2200
wtrl might do 14, rdwr might go lower (13 is the lowest i have seen), trp and tras might now be as low as they can get yet..
some timings and required voltages are just down to lottery, f.x. not all a-die can do trc 36 at these speeds

I said I wasn't going to do a YOLO but it's Saturday so I thought we'll do one! Underway :ROFLMAO:

1.6v on the memory just now, not sure what most others doing 6400 tCL28 sit around.
Click to expand...
My Dimms can do 6400 cl28 at 1.50v VDD but some need more and as long as you can cool it should be fine.

Has anyone tried "Bykski DDR5 Memory Copper Air Cooling Armor"?
Image
I don't have a custom loop, nor really planning on putting one into the torrent so no fancy DDR5 watercooling for me.
I thought maybe I could solve potential heat problems with these. Corsair heat spreaders on their vengeance line is kinda eh.

Edit: Alternatively I could just 3d print a fancy bracket to hold a fan over the sticks. It's a difficult fit with a 2 DIMM mATX board + fuma 2 over the cpu but I'm sure there is a solution somewhere :p

Your CPU clocks look fine, a 105 BCLK only nets ~ .4ns

OS can have a huge impact on latency / try running in safe mode so you can see how much your OS is clogging things up.

Here's mine for example:
VDD: 1.55 VDDQ/IO: 1.30v VSOC: 1.24v
Still trying to optimize OS for 55.xx ns
CPU is "average/ SP 90" at best but DIMMS are "Super Supreme Mack Daddy Tier" lol.
Cooler Score: 170 - 360MM AIO / MX6 Paste

Thank you, that did the trick. I guess my OS is very bloated, my results were not closer to 60. I had 60-62 ns latency. That makes sense now. :)

No idea why but OpenRGB doesn't show my RAM.

I found the old ASUS aura sync that is standalone, it works. But it's still bloated crap lol, and yes, it runs a service on Windows start to sync settings. I'm just interested to see if the RGB off reduces power draw max in HWINFO. Next kit of DDR5 I get will be RGB free, like my b-die kit was.

I can boot 6600 1:1, but I got a BSOD 7 seconds into Karhu with fairly loose timings. Might be scope for messing around here with voltages/resistances, but @LtMatt has tried like 5+ 7950x3Ds and none 6600 1:1 stable. End of the rainbow stuff right now as I'd prefer to get some daily profiles up and running so I can play around with this CPU.

I'll definitely check 2133 vs 2200 in benchmarks after I do an overnight Karhu run for 6400C26.

VDDP was at 1.05 at the time of screenshot, I knocked it down to 0.95 just now. VSOC is at 1.1 - can low SOC voltage affect latency?
Just ran at 1.25 SOC to check, still the same. Not sure what is it.
Click to expand...
If you get errorcorrection: yes. On AM4 too low soc caused higher latency/worse performance.

I also have the Teamgroup DIMMs and they appear like this. I have disabled all other devices in openrgb. In BIOS I have set the "aura off" when system running option, not sure if that matters

Being able to run 6600 MT/s is IMC lottery. Nitro settings matter: I can run disabled/2/0 for 6400, but 6600 needs 1/3/1. I need fairly high VDD (>1.7V) for 6600 CL28, so I don't consider it better than 6400 CL26 / 2133 (I can't do 2200 FCLK) for a daily profile.

Ah yeah, the ASUS crap might be interfering with it. The good news though is I managed to use the standalone Aura sync to turn off the RGB and it has stayed off even after about half an hour of uninstalling ASUS crap and even having to manually remove leftover Asus services.

I swear ASUS software is like a genuine virus. I once thought iCUE was quite bad, but it's come on a bit and isn't really that bad now if you have a corsair watercooling ecosystem.

I also totally forgot about Nitro, it's currently turned to enabled but set to Auto. I'll need to pay more attention to it now.
