New Agesa released 1.0.0.7B, massive memory speed boost for Ryzen 7000 on AM5, up to 8200MT/s now stable on Ryzen!

[wookiee87]

i've got dominator expo 6000mhz ram and with the latest 7b update i installed earlier i can run 6200mhz no issue and on a 1:1 ratio, tried buildzoids ram timings but ran into problems with bios freezing had to clear cmos a few times to get my pc to boot again, the sweet spot with the newer bios's look to be around 6200-6400mhz max, i would still look at 6000mhz kits and see how far you can overclock it and save some money.

not all cpu's will be able to hit 6400mhz but most will do 6000 easy and with some tweaking in the bios 6200mhz should be doable, any more than 6400mhz and the cpu will have to work at a 1:2 ratio and the increased latency wont yeald anymore performance regardless if you can run 7000mhz+ in games, benchmarks may be diffrent but haven't tried

What chips does your dominator kit have ?

I just brought a new G.SKill 7800mhz kit, right now im at 1:1 6400mhz CL30 and running a ram test, going to push for 6600mhz 1:1 which I believe is the limit if the CPU can do 2200fclk, otherwise i'll come back down to 6400mhz and tighten timings, ive booted it and ran some tests at 7400mhz 1:2, the difference is un-noticeable even in AIDA cache and memory benchmark, it wasnt stable and it a nightmare to try and get stable including stupid voltages.

EDIT: So 6600mhz was a no go at 1:1 with 2200fclk, 2167fclk didnt work either, so I tried 6400mhz CL28, the PC posted but locked up, im already at 1.4v so dont want to push any further on volts, so im working on secondary timings to bring those down now.

my dominators are SK Hynix, i can do 62000mhz no problem at all on stock timings and 1:1 but am at 1.4v even at 6000mhz, kit is a 30,36,36,76 out of box, buldzoids timings were a no go even at 6000mhz, bios options would not change and pretty soon it just locked up, got a long way to go tbh, if i change any of the secondary timings too much i just get lockups and my cpu is a lemon too 2100mhz fclk is about the limit what i can do

my tRP and tRAS are really high (55,141) but again if i drop them too far i get no post errors / overclocking failed, i need to have a really good look and figure out the secondary timings

I’ve not switched over to this yet but I’ll get my bios updated asap to 1516.

Strange, ive had M die and A die running at buildzoids easy DDR5 timings without any problems, this new kit is A die, it should be 7800mhz 36-46-46-125 but right now its at 6400mhz 30-38-32-28, see if I can get that 32 down to 28 and then start on trc and trfc

had mine from when i moved over to 7000, getting 6000mhz to work back then was a big chore but i managed it, but after multiple bios's to improve stability and ram, i can say 7b (1516 on my asus board) is really good, can run 6200mhz on a 1:1 ratio with minimum effort, its just those pesky secondary timings to work out at the higher speed, but atm seeing a nice boost in most games i'm playing and more importantly no crashing

I cant even post with 64gb (4 dimms) on my asus x670e extreme with a 7950x3d and teamgroup 7200mhz ram

I enabled nitro mode and docp ii, set it to 6000mhz and it hangs with FE bios code. I thought this could be the code for the 5 min nitro memory test but I've left it over 15 mins. Can anyone witht the same board tell me which led code it sits on?

Annoyingly the old bios handled 6200mhz perfectly, now I can only post with 6000 and have to have nitro mode off. It's probably not thoroughly tested with 4 dimms.

getting 4 sticks to run above 5600mhz will be very hard the more capacity and physical sticks you have the speed has to drop, all testing with 7b from what i have seen and looked over is dual channel kits, its highly dependent on your cpu too, if you get a good one then you may be very lucky and get close to 6000mhz with 4 sticks, but most ppl run around 5600mhz with 4 sticks of ram and just tighten up the timings a bit.

i bet if you take 2 sticks out you'd post expo at 6000mhz easy and perhaps upto 6400mhz with some tweaking

 

[Tom B]

I can run 4 sticks at 6200 by just setting DOCP II in the old bios though. No effort required. I can't even post at 6000 with 7b.

if you could post before with such a high speeds with 4 sticks why on earth did you update, 7b enables very high ram speeds but at a 1:2 ratio with all cpu's, there is no benift in games running 7000+ vs a tuned 6000mhz kit, even a loss in some cases. there is a update coming which will be agesa 1.0.0.7c, earlier on in the thread i checked what the changes would be and it turns out 7b dosnt play nice with samsung ddr5 modules at the moment, 7c is supost to fix this.

Its possible your ram are samsung branded hence why you cant boot, check cpu-z and under memory tab check the manufacturer, if its samsung then you have your answer, unfortunatly have to wait for 7c or perhaps roll back

 

[Tom B]

It's SK Hynix so should be fine, it'll be interesting to see if 7c does make any difference once it's available. I've gone back to the previous bios for now

 

[Jamin280672]

I guess running 1:2 does make a bit of a difference, this is using buildzoids test timings, at 6400mhz CL30 my read speed was 90***MB/s, write was 92***MB/s, Copy was 82***MB/s and latency was 63.3ns, might push for 7600mhz overnight and see what happens, or push for CL32-42-42-42, I dont really do much gaming anymore, so its more about performance for me.

 

[g67575]

Using the lower speed IMC ratio probably results in about 5ns higher of latency or more in Aida64.

It should be possible to test the differences at 6400 MT/s, running at 1:1 and 1:2. Could someone test that please, with the same memory timings?

In terms of memory bandwidth, it does seem as though we're not really getting the full benefits of DDR5, at least not without DRAM sticks running at ~8000 MT/s.

I wonder if they will increase the infinity fabric clock with Zen 5? My BIOS lets me increase this to 3000 Mhz if I recall correctly (don't try that ofc), so maybe future processors might be able to run at this speed natively, allowing a 1:1:1 ratio with 6000 MT/s DDR5.

When you say "to get my pc to boot again" does that mean to show any life at all?

DDR5 can take 3+ minutes to perform training, so sometimes it is worth letting your machine sit after a change of RAM or large change to your frequency to see if it can re-train and post. Generally, there will be no indication of life while this happens...

i ment when i loaded buildzoids timings my pc would not boot after applying in the bios, i waited 15mins with a black screen and stuck on error code 15, that was at 6200mhz, i cleared cmos and eventually after it trained for 2-3mins (4800mhz) i got back in and set xmp but changed speed to 6200mhz from 6000mhz, all my sub timings where basically stock and hey presto pc booted pretty quick and everyhting was fine, i did try 6400mhz but i wasnt able to get it stable i could get into windows and then get a bsod if i moved the mouse, i'm already at 1.4v on my ram and not willing to go more incase i do anything to the cpu's imc.

plus my dimms get pretty warm mid 50's under load and 46-47c idle.

Fair enough! That's really interesting they wouldn't even train....

Fwiw, My system is unstable at 1.4v memory but rock solid at 1.35. I'm using 4 dimms so a bit different. I cant even get it stable at 5800 with 1.4 but 1.35 is good for 6200!

Counterintuitive but less voltage is better for me

complete oposite for me i can run 1.35v with expo settings applied (6000mhz) my kit is a 1.4v out of box, but trying 6200mhz results in no boot, i have to use 1.4v if i up the frequency on a 1:1 ratio, havent tried 1:2 yet, pretty happy with wher i have it now soc is around 1.325v which isnt too bad.

Max for Soc is 1.3v mate, you shouldnt need anymore than 1.2v though for 6000mhz to 6400mhz, im at 1.275v for 7600mhz and going to push for 7800mhz if 7600mhz passes overnight memtest pro run.

On that board you've got you should be able to easily reduce soc, ive got the Gene, you've got the top end board from ASUS.

 

[Brizzles]

And YES its not stable, not even close.
