Share your AIDA 64 cache and memory benchmark here

Great thread, learned a lot so far. In particular, thanks FilipM for posting your results, they were a great baseline for me.

Looking for some advice, I'm chasing as much performance in Warzone as I can get. It seems like GDM really hurts my framerates in Warzone compared to 2t but getting 2t stable with 4x8 Viper B-dies is a real nightmare. I've been trying to pass 1900fclk for over 6 months and I'm convinced that's as high as this CPU can go.

Does anyone have any suggestions for changes to my timings? With only 2 dimms I was able to hit 52ns but with 4 dimms 54ns is the best I can do. I added the extra ram this week to try to improve my minimum frame rates in Warzone. It seems like it helped the average frame rates but the lows are still awful. What I'd really like is to keep the FCLK at 1900 and switch to 2T but I don't know where to go with my memory timings.

Voltages: Right now I'm running Auto Vsoc, VDDP, CCD and IOD. Ram is 1.45. Every time I try to change them I get less stability and worse performance.

CPU OC: Running PBO - PPT 185w, TDP 125v, EDC 170v. +200mhz -25,-25,-15,-25,-20,-25. Scalar 1x. Should I try 10x?

When I play Warzone my CPU never goes over 4.7 ghz, does that mean I should try lowering the +200mhz core down to +150mhz to see if I can get faster consistent all core clocks?


Warzone performance: I go from up to 270 fps down to around 200 with occasional dips to 150 which drive me insane. I have an RTX 3080 and a 280hz monitor.

My Asus Tuf X570 motherboard has a Digi VRM section, should I be changing anything in there?

It is impossible for me to stabilize anything over 1900 with 4x8 on my 5900X. Actually, I cant stabilize anything over 1900 with 2 sticks on my 5900X either. I tried man, There is some kind of limit, I think its the CPU. Its been to 2000 with 2 sticks, but it turns into a WHEA generator and spits them out by the thousands :D My 5600X has no problems sitting at 2K stable as a table, but tough to nail down anything after. Its been to 2100 a few times, its just for show though no chance of stability for me at that speed. I suppose it could be AGESA putting a limit on things too, but I find it to be mildly unlikely.
 
It's the IOD having 2 CCDs communicating to and fro with it.
 
Its a problem voltage cant fix :D

At least not with mine..

Your result is very good, you can play a bit more with Curve Optimizer .

Messing around with 4 sticks of Crucial Ballistix (Micron E)
Nice tRCDRD 16 have you tested it using TestMem5 etc?
If you could post ZenTimings with VDIMM that would be great. Heres mine but with Dual Rank Micron E.Die

I tested it with AIDA64 and the built-in membench in the 1USMUS calc. It would also run the tighter 3200CL14 timings at 3600 with more voltage. That CPU with the very good memory controller is no longer on my test bench though. Currently testing a Ryzen 2700x, which so far is a disappointment.

What voltage did you run for the RCD 16 @ 3600? 1.45?

For the 1600AF it was 1.36v.

For same setting with this 2700X it takes 1.44v or it won't even POST. Crazy stupid weird huh?

That 1600AF is Zen+ same like the 2700X both 12nm so it is weird.
Uping the SOC can help sometimes with DR Dimms or 4 SR Dimms.
 
I think it will improve a bit better, but currently im testing lowering my CCD and IOD voltages. Any tips or advices are welcome.

@Taraquin , @freeagent , whats yours thoughts? Sorry to mencionated but you guys was who helped me a lot in that long journey.

Disabling GDM did improve performance.

Try a bit lower ras and rc, but keep 14 between since ras+rp=rc, with your voltage maybe ras 24, rc 38 works? Rrdl 4, wtrs 3, wtrl 7 or 6, wr 12, rtp 6 (wr=2 x rtp), rfc should be divideable by 8 og 8gb kits so try 256 or 248. Not sure if it helps, but worth a shot. Getting wr=2 x rtp might be most important :)

I was playing with my 5600X yesterday, that little CPU is such a tight unit, love it..

And I just ran this one now..

Here's another run of mine at 4000 mem cpu stock

And here is one with ram at 3600c16 and BCLK at 105, as i want to see if it makes my PC unstable. You can see the ram speed boost from just +5 BCLK
