I don't think you can go wrong with the x570 Tomahawk, lots of people on the forum using one, so you should be able to get help if needed.Think I will deciding on the board so far have my eyes on the MSI X570 TOMAHAWK WIFI

Thats my point lol.... doesn't matter how many times I click on the drop down arrow I get nothing just a green line.It doesnt look expanded on your screenshot
Are right, lol. Not sure then, sorry. I thought it just needs expanding to see the CCX and coresThats my point lol.... doesn't matter how many times I click on the drop down arrow I get nothing just a green line.
No worries haha, starting to get my hair off with it a bit so just going to leave it for now.Are right, lol. Not sure then, sorry. I thought it just needs expanding to see the CCX and cores
Has anyone noticed that dropping EDC,TDC,PPT and playing with LLC drops L3 cache performance? I noticed that my clocks were high 5050mhz single and 4750mhz multi but L3 scores in Aida64 were tanked for R/W/C. As soon as I raised EDC noticed they went up. Ex:
R20 Multi Core
EDC 110A 4725-4750mhz- score 6150-6200pts Aida-R-175GBs/W-310GBs/C-180GBs
EDC 135A 4625-4650mhz- score 6225-6320pts Aida-R-210GBs/W-335GBs/C-354GBs
Ya, I've read of clock stretching. Those clocks were from HWinfo as the effective clocks. Was also just surprised to see the L3 dropping. guess that's a sigh of clock stretching?Yeah, its clock stretching. with a lower EDC the CPU isn't getting enough AMP's so it errors out, always verify your clocks.![]()
What happens if you leave the CPU at stock but set either the 95 or 65w Eco modes as those reduce PPT TDC EDC.?Ya, I've read of clock stretching. Those clocks were from HWinfo as the effective clocks. Was also just surprised to see the L3 dropping. guess that's a sigh of clock stretching?
Hitting PPT/EDC limits should be dropping clocks before resorting to clock stretching.Yeah, its clock stretching. with a lower EDC the CPU isn't getting enough AMP's so it errors out, always verify your clocks.![]()
@Mr. Sunshine I found similar. 110 EDC limited my L3 cache read to ~230 GB/s even thought HWInfo64 was not showing full usage of EDC.
Upped it to 135A and now back to what is expected
110A

Another observation. Memory intensive workloads like TestMem and DRAM calculator benchmark tend to max out EDC while staying way below PPT. Resulting in nice all-core 100% load clocks of over 4.9GHz.
PPT part makes sense, there is not much for CPU to do except load/store to memory. Only L3 cache is probably getting hammered.
Edit:
umm, why is my L3 so much faster than yours?

With my board set to 65w eco mode which limits EDC to 90A I still see 350+ on L3 so maybe its a board/bios issue or another setting effecting it.

Edit: stock is showing slightly higher on 400+ on L3 so maybe it does somehow effect it.

Remember reading somewhere that lower L3 speeds are indication of memory instability. Mind running AIDA with full stock, load optimized defaults?Thanks too. Yes, I expect a board/bios issue. Are there any similar programs to AIDA that test L3 cache speed? That would rule out AIDA at least
Scroll a few posts up. Joxeon appears to be using a B450 Tomahawk max, looks fineAnyone have any first hand experience running the 5000 series on a B450 board? Any issues etc? Wondering how well the B450s are supporting the 5000 series.
