Typically speaking If you keep temps under 58c most A die will not produce errors. I just pull rgb difusers off so i can actually cool memory and not a piece of plastic......while the supercool setup is badass........I change memory like women change shoes.....it's just not realistic for the test station. Better suited for having binned many kits and then installing on a known kit and shoving in a daily. To further explain this lets take a look at some testing i did....... Test 1 low speed fan......as you can see max temp hit 58c......which resulted in an error in y cruncher fft on amd this is ( vst to intel ) . Test 2 server grade finger chopper fan......was able to maintain a temp under 58c while at 2.15 vdd..... I ran 10 mins because for a benchmark like 32m I need 5 mins......if i can survive 10 I can "benchmark" anything. Also y cruncher fft tends to run mem hotter than any memtest on AMD i can run so this is fairly worst case....... Performance is a trade blows scenario in most cases.....I use good old 32m pi to really see what's what. Until we get working multis at 82x I'm reserving the right to say that typically in everyday workloads 1/1 is just going to be easier and faster........If my math is right cl 32 8200 will be the break even or surpass point unfortunately although I can test it once you introduce eclk into the mix it brings effective clock issues skewing data so I really need a working 82x to do a fair comparison. Can't pull off 8000 c30 and cl32 8000 is actually slower by 1/10th. Please note vcache cpu's are 10 seconds faster cpc......this is specifically for non vcache 5 gig low clock challenge....which I own both best results still to this date for vcache or non vcache......

2 dpc........ And I maintained performance.

Here's some super low bin non binary M die on intel. Typically this translates to GDM on capability on AMD. Intel is useful as a template to figure out what you can pull off on AMD. Can't be a true mem guy unless your versatile and since intel has been doing gear 2 longer can learn alot of things to carry over and test on AMD.

24x2M is going to be slower than a good 2x16gb kit. M die shines with Gdm on but gdm on is slow. You can get away with alot more gdm on. GDM off the main things are trtp needs to be 16 or higher. you might have to back off twr. almost guaranteed trrd ls tfaw needs be 8/12/32. You will lose some trcd. you will lose some CL. I can run 8000 36/47/47 170ns gdm on 8000 np..... When I run karhu though mb/s is in the 300 range. GDM off that gets knocked to 38/48/48 but gets me 319mbs in karhu On A die with a good tune typically you want to be and should be in the 330mbs range on a 7950x and 260-270mbs on single ccd.

Luck is one cpu. I rely on mostly skill and knowing my particular hardware in an out electrically. Here's another cpu on another kit of memory on another spare tachyon tested tonight on air noctua cooler......power spec 750 psu.......ala worst case testing. Limited to 1.43 vdd/vddq as this was merely hash out Imc test.

Max boot to bios.....lose vga higher......here i've lost sata so can't boot to windows...... 8800 without multi's......

Low vddp helps the most. 1.0 range. I'll give you a breakdown. CPU_VCORE (CPU Core and integrated GPU voltage supply) CPU_SOC (CPU system uncore voltage, memory controller (UMC), north bridge IO, SMU, FCH, DF...) CPU_VDDIO_MEM (CPU memory I/O voltage, and the voltage supplier for VDDP) DDR_VDD (DDR PMIC VDD Voltage) DDR_VDDQ (DDR PMIC VDDQ Voltage) CPU VDD_MISC (CPU misc voltage for PCIe, internal clockgen, and most important, VDDG voltage is driven by this voltage) VDDP (CPU DDR Phy voltage) VDDG (Global memory interface(GMI) voltage) for Zen CCD/CCX overclocking, CPU Vcore and CPU Vcore loadline calibration for Infinity Fabric, CPU_SOC, VDDG and MEMCLK for memory overclocking, VDDIO_MEM, VDDP and CPU_SOC(UMC) for VDDIOMEM CLDO, VDDP < VDDIOMEM for VDDMISC CLDO, VDDG =, <, > VDDMISC CPU_VCORE's internal regulator for igpu is not exposed Knowing this and knowing 1/2 uclk is less your SOC requirements will also be less, Board choice should not really be a big surprise.....lets look at intel for that matter.....at the end of the day it's ddr 5 and signalling that is the enemy. 2dpc intel your lucky to get 7600. 1 dpc imc is limit. No different with AMD. I manage to get the giga extreme working good but I have been working on board with giga for awhile.....my tachyon b650e (1dpc) can still take the same cpu further. My voltages are as follows. 1/2 tuning is not the same as 1/1. Vcore auto vsoc 1.25 vddio auto ( 1.3 ) vmisc auto ( 1.1 ) vddp 1.025 vddg 850/850 vdd 1.625 vddq 1.525 Start with Hci or karhu (cache enabled ).....or your wasting your time. Tm5 good for catch mem issues not imc. ycruncher fft will also catch imc. I also have an intel tachyon setup...that said i'm already used to what it requires to get 8000 stable.

Board matters....especially in asus department atm.....only ones doing 8000 reliably is Gene aka 1dpc. Giga's in a fairly decent spot with it's 2 dpc boards however even unobtanium tachyon ( actually have 2 but refraining from using for the testing i'm doing atm ) is beating my extreme. The asrock taichi lite is also doing very well on 2dpc. That leaves poor mans 1 dpc boards. Msi has no GDM options. I haven't heard anything about Asrock itx doing 8000 yet. The giga itx we know can do 8000 and it seems the asus itx can to. Voltage wise less is more. vddp in the 1.0 area......vsoc 1.20-1.25. My vddio is auto (1.3) uclk requirements in 1/2 are less so vsoc requirements are less......

Never think always know and have the data on hand to prove it so when you do performance testing no one can debate the fact that your results are this or that becaesu your probably not stable....... This is for a 1/1 versus 1/2 battle on non vcache to settle the performance debates. No clue what I will get out of 1/1 on this cpu yet on this bios......

I have a 4080 in my daily so not to concerned about 7800xt. First NV card since the ti 4000 series. I think i broke every version they ever made of those.... It works. AMD dropped ball on raytracing 1 to many times for me. When they get there crap together i'll go back to AMD. For now though and for my use case 144hz 1440P the 4080 does what I need it to do.

Thats a little narrow thinking. Currently using a 1 months old be quiet dark power 1600......has more than enough connectors for anything and everything........

Not anymore. AMD forgot I ever existed. All self paid for cpu's on hand. 40 something hours y cruncher. 500 loops 10gb linpack.......... Prime Blend cooking now.

this is the most boring part of what i do......only about 40 more hours of hashing boring stuff out.......

Older new canon fodder. Hotter tune in the 2 dpc board. See how this performs once I get all the stability tests under it's belt.

I got asked to post a bunch of tests.
