RMA request with AMD was approved all that's left is packaging it, and sending it too Miami Florida. AMD of course wants to do a visual inspection before sending out a replacement. CPU has been hanging out in the plastic clam shell in the retail box.

Finally broke 108s, looks like tRFC all of a sudden decided to start mattering again, and a big difference at that.

Anybody able to run both 3800CL14 and 4000CL16 on Ryzen 5000 able to give me some membench results? I can't compare the two as there's something preventing me from doing 3800CL14 on my Viper Steel, not even 14-15-15 or 14-16-16.

So lads, looking into Dram calc and... my ram isn't supported?

I have Hynix MJR?

ram ran upto 3800 1:1 fine, but i got a few WHEA errors, so i wont bother with that until the new AGESA is out improving on the OCing

i wouldn't bugger with hardcore ram OC until new BIOS come out, prob will be less than 2 months, AMD knows they need to make good on that promise of widespread 4000 1:1 possible.

if i can get 4000 1:1 on a chip that boosts over 5GHz, all the OCD's will be pleased

I looked in my MSI X570 Tomahawk BIOS, There are two sections for PBO, like 8 different modes I can pick from, Enhanced Mode 1-4... it is all very confusing, so I just decided to stick with 'Download Ryzen Master, don't touch mobo BIOS, check the Auto OC in ryzen master software, reboot... and done'. I only boost to around 4750, but its usually on 2-4 cores at same time, and cinebench confirms with higher scores. Temps are great.

Would love to see if mine would boost to 5ghz, but there are literally like 30 settings to choose from under all the PBO stuff... this mobo went way to overkill with it and it's to complicated. If I could get Buildzoid (who also uses x570 Tomahawk to show me how)... then maybe I would. Hopefully he will post a 5600x oc guide to his YT channel soon.

@Mussels what's your cinebench r20 single core score? mine is 611 with ryzen master auto OC, and 593 stock.

I just slapped in a 5800x in my strix-e. I got it booted at 4000mhz dram with some slow arse timings for a baseline. But get this, soc voltage is still on auto. I'm using g.skill 4000mhz c17 2x16gb kit. Now time to dial this in. Btw, it took my ole 3800mhz c16 settings w/o issue.

you 100% sure Infinity Fabric is set to 2000? I have seen many 4000 kits that only register in BIOS at 1900 IF, even though the ram is at 4k.

that is nice a kit btw if you really are running 1:1, what brand? care to link from newegg?

care to run AIDA64 latency memory test? I am curious what your ns is

 

[thesmokingman]

Yea its running the right fclk, would be pointless to do so otherwise. I'm not ready to run aida yet, it'll be slow as heck with the current timings. I'm still dialing it in at this point learning this imc's characteristics. So far it boots on auto voltage or manual 1.1. Timings wise dram calc doesn't have anything for this speed so its a slow and painful process. I just set the primaries to 20 and auto'd the rest. Edit, did an aida run got 62.1ns at these slow timings lol.

Nice kit of B-die. Why not just run the XMP 17-18-18 1.4V? It won't change how your IF or IMC behave. If you let it Auto its way onto Geardown you'll be running 18-18-18, but that's still decent, all things considered.

Ryzen 3000/5000 UMC is still capable of well over 4000 on its own, the B-die is clearly on the higher end of B-die, and IF is honestly just a can-you-do-x-speed-or-not affair.

Relying on DRAM calc doesn't always work out very well on real performance at the higher end.

What makes you think I didn't already try the xmp?? I'm not relying on dram calc, did you not read that? Dram calc doesn't even support speeds above 3866mhz.

Does it boost to 5GHz under a single-threaded load (R20 etc)?

I enabled +200MHz max frequency on PBO and I'm getting up to 4.8GHz in some cases with light loads, but under heavy single core load it will hit a max of 4.64GHz (which I believe is the rated max boost frequency anyway).

Yoou have to raise the power limit on the cpu. W/o a higher ceiling PBO can't do much. With PBO switch it to advanced under the cpu advanced menu but not in the tweaker area, the cpu area. That's where the real control is under the AMD CBS/OVERCLOCKING area. You can either switch PBO to manual or any of the other modes. I use motherboard and raise the power limit in my strix-e's vrm tweaker section.

Yep, the +200 is all i needed and each core is passing 5GHz sooner or later, according to HWinfo

Its so weird seeing the tables turned on Ryzen. 1st Gen liked TIGHT timings and mid-low speeds. The new ones want high clocks and middle of the road timings.

I've been fiddling with my 4x8GB kit of B-Die.. K4A8G085WB-BCPB Manufacturing date of June 18-21, 2020 with assembly in August. 3200Mhz @ 12-13-13-28 @ 1.375V. I hit a wall at 3466 @ 14-14-14 so went for the tighter timings to see how well it'd do. Does better with tighter timings.

I'm not so sure. The default latency of Zen 2 is 71ns and Zen 3 improved that to 62ns roughly. All the chips though will improve a lil with lower latency ram since that is the one weak spot of the design. It might look like it's not a big deal on Zen 3 but I think that may be just because Zen 3's latency was improved to such a great extent. And when put into context, the L3 cache was doubled and that implies a 9 tick (ns) penalty which is added on top. Thus AMD not only lowered the latency, but they had to jump thru a whole other set of hoops to overcome the added latency of the extra cache. The end result is 62ns at 3200mhz with average timings. If you look at some of the crazy overclocked ram setups, you'll see some guys running stupid high dram speeds with shockingly tight timings (4200mhz/2100 fabric cas 14) netting them around 48ns. That is nipping on heals of Intel latency!

3200 cas 12 mighty impressive... can you run aida64 memory test ands hare your latency ns score? i am curious...

my 3600 cas 14 is hitting 57-58 ns range. i'd like to get it down to 52ns when the new bIos hits in a month or two.

So some fun Hwinfo stats after playing some starcraft II on ultra for a bit.

All cores hanging around 5GHz (i'm slightly undervolted atm)

temps: high compared to previous gen, but running great for this gen

Giggle, i just love the AIO on the GTX 1080

DX9 games just do not require much electrical juice to run...

This test? Best I have so far is 3800CL16, CL15 is not doable, GDM:OFF even if I try to tweak everything is super unstable. I haven't tried going to CL14 yet, I'd rather have 4000CL16 if they fix IF with further bios updates. My boots with Memory set to 4000MHz and FCLK to 2000 but it drops tons of WHEA warnings.

 

[Ruru]

3600 @ 4.3GHz all-core here. Still haven't got faster RAM, I know that I'd get extra performance with faster RAM, but it's not on the number one on my to-get list.

whats your aida64 memory latency? im curious how much it varies between these programs. i get 64ns in 1usmus, but 57 in aida64. 3600 cas 14 dual ranked.

Thanks for the results, looking for 14 tho. I have Renoir 4650G; 2000 is not a problem. Our 3800 results are comparable.

But my B550I AX refuses to post 3800/14 on my B-die, so just curious if I stood to gain anything from 4000/16 to 3800/14 if I could make it work. I need extra VSOC to handle the 4000/4133 speeds right now but I could relax it for 3800.

All of the ~108s record holders on the spreadsheet are running 3800/14 because Ryzen 3000 can't do more speed. Still haven't found a submission button for my 107s result

You 5000 guys are already kicking my ass on AIDA latency, but it looks like actual perf in membench is about the same.

If you want to try odd tCL you have to do as Intel guys do and run 2T. It's not ideal on performance and may be slower than CL16 GDM, but thats the idea behind GDM.

lowest I saw in AIDA with 3800CL16 and optimized subs was 54.2, pretty consistent in 54.x range

I'm tempted to play with it but I don't want to break overall great stability. I found that it's very easy to improve benchmarks at the cost of WHEA-19 warnings. With the current settings I can do 20 cycles of TM5 or 30 minutes of OCCT and not only it'll pass but won't generate a single WHEA error.
That's why I left FCLK 2000 for now, tons of errors and results worse than stock.

Disabling boost works quite well. In gaming the max Vcore drops from 1.45V down to 1.0V, temps from 82C down to 62C and CPU power consumption is down 30%. The only drawback is a maximum speed of 3.7GHz but now that summer is here it's a good thing to dial it back. I've noticed that the 5600X slowly warms the room up during the day.

I think if you want to save some temperatures & still have performance in games then disabling SMT (AMD's HT) should do the trick. Or playing with ECO mode (or manually lowering power limits).
