Woud really love to see whether or not ddr5 performs well with ArmA3 Just got contacted elsewhere by a dude who apparently bought a 12900k with speedy ddr5. No direct comparison to ddr4 but at least we'll learn about alder lakes arma3 performance. @Groove_C i told him to contact you regarding the avx2 malloc, as i dont find the file and armaholic is gone unfortunately 😪

I have certainly not been living under a rock and as said and as you agree, there are CPUs that are artificially reduced in core count which are just the same as the top tier models and then there are the ones where a core is defect and where those are used to produce lower tier SKUs. But there is certainly none which are selected based on the IMC or uncore frequency capabilities. The max spec is 3200MHz and all of them work at that. OC is OC and they dont bin for RAM OC. Neither of them, AMD or Intel. Core Voiltage is also identical between 5600x and 5800x. Two CCD Models might be selected at that end, but certainly not the lower ones.

There is no logical explanation for such a difference. They disable two cores because one might have an error, but that does not necessarily mean that other parts of the chip are affected. Same with Intel. I don't see a reason why lower tier models should not reach the same memclock or uncore freq. In fact, I had a 3300x CPU that had no problems running FCLK 1900+ and 3800MHz RAM. And in most cases, they disable cores not because they are broken but just to diversify the products. There are more 5600x sold than 5800x, yet there are for sure more fully functional dies coming from the fab then ones with defective cores. Last not least, the fastest on the current list is this one: https://imgbb.com/0tSC7XB And I want to pick up your statement again that Ryzens are slower at high quality settings. Do you make that up or do you have proof? Its the first time I hear that.

But money matters for most people 😉

Sure, I fully agree. My point was, the 102FPS documented have not been a particularly obszene result for a 5800x as I get 97-100 with a bad sample, SR RAM, an ITX box, and a 30 Euro cooler. That was the only thing I wanted to add to the discussion. Min FPS for me are about ~71/72 on average. And by the way, I am hard limiting mine to 95W power draw. EDIT: Also the lower the settings (resolution/quality), the "better" Ryzen is, due to it's cache. But nobody plays at such settings. Once you go for 24/7 settings, the picture is different. Thats the first time I hear that. Do you think so or do you have data on that?

But you know my results, so it is proven that 97-100 FPS average is where you end up with a properly tuned poor mans 5800x system with good but not great RAM. And my 5800x I got cheap, because it was the worst in a binning done by a few folks I know. But you know all that. We talked about it.

This screenshot for the 102FPS 5800x was very good no doubt. But it wasn't one in a million. I have a 5800x myself meanwhile. 2x8gb Single Rank RAM at 3733MHz CL15, mild CPU overclock (101MHz BCLK), no curved PBO, Beta Bios on a X370 Board, 30 Euro Air Cooler in a mITX System and I reach 100FPS myself. So for sure this Sys was fast, but the statement it was a golden Sample for ArmA3 and a lucky run that is out of range otherwise is not true. What the RKL can do we will have to wait and see. So far I haven't seen one that reached 100FPS+

It seems that AMD did the evil thing and integrated a ID check into their Firmware. To make it short, any BIOS newer than AGESA 1.1.0.0 Patch C does not seem to work with Zen3 on X370 Chipsets. That said, crossflash worked very well with Zen2 and gives all the nice features including rBAR and per CCX overclock on the X370 Board. Certainly worth it if you are willing to take the risk but it won't help with Zen3

@Valken The system specifics: Mainboard: Asrock Fatal1ty X370 Gaming-ITX/ac Motherboard - I had bought it back in 2017, originally paired with a Ryzen 1700. AsRock leaked some beta BIOSes for their old B350 X370 lineup, you can find the deitails with google. For this board it has been the BIOS 6.61. But this only works with a couple of AsRock Boards and the BIOS is surely beta. For B450 and X470 Boards, there is official Zen3 support, so for a budget build, those could be used or upgraded if already there. CPU: the mentioned 5800x. For now, I only borrowed it from a friend who was screening several for high IF capabilities. This one failed to achieve 1900MHz IF without WHEAs and he was nice enough to send it over for testing on this board,. This is why I also run it at 1866MHz and 3733MHz RAM. Cooler: Scythe Kotetsu Mark II, a really cheap but not bad cooler. However, I should mention that I realized before, that the cooler is somewhat convex which is why I sanded it a bit to make it fit better on my previous 3300x ryzen heat spreader. No magic, I just used my thumb and some sandpaper to make it a bit more flat in the middle of the plate. With this cooler, at the end of a cinebench R20 run (multithread followed by a single thread run) HWinfo gives a peak temperature of about 83 °C. I think that's perfectly fine given the load which will probably never be the same during gaming. RAM: 2x 8GB TridentZ 3600MHz CL15, so single rank B-Die RAM. To be honest, the kit has a great reputation and has been very pricey but I never got it working with true low latency. It gives a reliable CL15 up to 3800MHz. 3733 or 3800MHz CL14 is definitely out of reach at 1.45V. Subtimings go ok with a tRFC of ~147ns. Not great nor bad either. At least with my CPU-Board combinations, i can't get further, but it never really mattered. CL15 vs CL14 is not a dramatic difference. Yet of course... it could be better particularly given the price I paid back then. GPU: MSI 1070Ti 8gb --- nothing special. PSU: 400W BQ power supply Chassis: Node 304

@Valken The funniest part is that this is all done with an unofficial beta BIOS from AsRock on my old AsRock X370 Fatal1ty mITX Board with a 35 Euro Scythe Kotetsu Mark II Cooler. So... this isn't quite a costly high end system

I finally got a 5800x to play with. Its not a great overclocker RAM wise and i only reach 3733MHz RAM stable, but its already very fast. The mid 70 fps results were from my 3300x.

A friend in the German Ryzen RAM OC Community (spawn off the Computerbase.de Forum) going by the name ZeroCoolRiddler, gives some pretty impressive results from a 5800x running Micron-E Dies @4000MHz 1:1 with the FCLK. To my knowledge, this is the first system to pass the 100 FPS sound barrier. Interestingly, his min. FPS hit a mind boggling 71FPS which is pretty much exactly what I proudly presented as the max. FPS my 3300x could achieve a week ago. The system ran the cma_x64 AVX2 malloc and a curved PBO, a new Zen3 AGESA function which allows a manually adjustable Boost behaviour in terms of frequency and voltage settings allowing to customize the boost behaviour with individual (and non escalating) voltage settings per core making curved PBO apparently the cpu optimizing method of choice on Zen3.

As a final assessment of the possibilities of a 3300x: This is 3300x @45W cTDP + PBO (+150MHz); 2x8gb TridentZ 3600MHz @3800MHz CL15 + Subtimings; XFX RX470 4gb @stock - CMA_AVX2 malloc - 1080p Standard Preset+S-key By the way, the board is an old school AsRock x370 Not sure. There is a whole lot of performance hidden in the subtimings and in particular for the Micron E Dies, there are settings that basically always work out of the box.

Thanks @Valken and thanks @Groove_C for detailing the malloc installation. I got it working! So here is the 3300x @stock + 2x8gb SR 3800MHz CL15 (IF1900) + Radeon RX470 4gb @stock 1080p standard settings + S Key; cma_x64 enabled Min frame rate was: worst run 40 best run 42
