Dancop Posted July 8, 2019 Posted July 8, 2019 (edited) Hey Fellas, Everyone was binning and buying A0 memories with the goal to reach 4200+ c12-11. For a very long time, this was the absolute way to go in all benchmarks, until Alva decided to show us the real magic on A2 during the GOC 2018 in Vietnam. From that moment on, a lot of people tried to reproduce these settings and even improve them. I think the G.Skill OC Worldcup then, showed what’s really possible on A2, where we showed 5100MHz C14-14 and 5000MHz C14-13. It was said, that 4800C14-13 is not really much faster than 4200c12-11 in for example 32m. Yes, that’s not wrong. But keep in mind, that 4200 or in best cases 4240, ist he absolute limit. 4800C14-13 is something that some guys can run on air and not the limit. I’ve tried 4933c14-13 and it was in fact faster and this is still not the limit…look at the screenshot: Due to the fact, many many people start using A2 mem and some high freq & low latency settings, Asus decided to put some further profiles into the upcoming BIOS files. Here ist he first one: ROG-MAXIMUS-XI-APEX-ASUS-0021.7z And here as well: https://filehorst.de/d/cbqoCxgJ And for the gene: ROG-MAXIMUS-XI-GENE-ASUS-0021.7z Now the how-to-apply guide. Keep in mind, that not all A2 mems and/or 9900k can do this due to several, known reasons! Please don’t give up on booting them, once it doesn’t work. DRAM VTT should always be around 0.9V-0.95V. IO/SA depends on your chip, but I figured out on 4 different chips, that too much is not really good! On all my chips, the max I needed was 1.35 IO and 1.4 SA. DRAM Voltage is best around 1.97 to 2V for booting. In OS I was able to raise the voltage up to 2.15 on some sticks. 4800 2V: This is actually the lowest profile. It should run on at least 90% of all Systems with semi good sticks. 4800MHz is quite high for an all air cooled system, this might be the toughest thing here – temperature! If you can’t boot this profile straight, start with 98MHz BCLK. Find your max bootable setting. Then raise the rest in the OS. ALL RTLs are Auto! Some kits require to set the initial value to 79 and both offsets to 20. 4800 1,97V: This profile is by far the toughest one. Only two out of all my A2 dimms did this on air. This is basically a cold profile. With a cold CPU I was able to boot this one with 8 sticks! With cold CPU and cold MEM, all parts did it immediately. The same rule applies to the 4933 profile. Here you have a profile, that gives you at least 8600 points in geek 3 single mem score at 5G CPU! Once you went cold on both, CPU and MEM, you can try booting this profile with 4933. I was able to do so in Taiwan. That made it possible to run this setting at almost 5g: If you can’t boot, with postcode 23 for example, then change the RTLs in this profile to auto. Now they are 62/63/13/13. Keep the initial at 79 and raise the offsets from 19/18 to 20 both. (this is a general rule for all three profiles). If it boots now, try lowering the offsets again to 19 both and keep the RTLs at auto. The offsets 19/18 is the lowest I got working and it really gave me the best performance! Keep in mind, everything higher than 4850MHz with c14 I needed at least 0°C on the MEM to boot! 4933 1,97V: Let’s call it the killing spree profile! With this profile you might be able to boot even with 5g divider! It’s not easy, but doable with the following how-to. 1. CPU and MEM cold 2. CPU is fine from -100°C to fullpot, MEM should be -60°C to -80°C for training. Once it trained, torch your mem to around -20°C to -30°C to enter the OS. 3. Try to keep the mem around that temperature. Unless you changed the bclk, your MEM shouldn’t be trained again and you don’t need to focus the temp. I hope you like this. Maybe there will be a Gene BIOS soon as well… Edited July 9, 2019 by Dancop 10 9 Quote
miker2ka Posted July 8, 2019 Posted July 8, 2019 How many of the 4 chips could do 4800C14 on ambient? like 25C room temp? Quote

Dancop Posted July 8, 2019 Author Posted July 8, 2019 Ht disabled, for ht I needed the cpu idle around 20 degrees, except my best one. That did it even in my room in Taiwan with aio Quote
unityofsaints Posted July 9, 2019 Posted July 9, 2019 Great work! Now we just need these profiles "backported" to the MXA 2 Quote
GtiJason Posted July 9, 2019 Posted July 9, 2019 Nice guide DC, is 4933c14 faster than say 4233c12 waza 32m ? or not possible on Apex X Quote
Mahameru Posted July 9, 2019 Posted July 9, 2019 How about XI Gene? Would be nice if Gene also get these profiles Quote
miker2ka Posted July 9, 2019 Posted July 9, 2019 I"m curios how rare are the CPUs that can boot 4800 on ambient. I have a feeling that they are much more rare that ram. I tested on 2 binned 9900k and none could do 4700c18 with ht enabled, even if the best one could go to 5000 in single channel. Quote

Dancop Posted July 9, 2019 Author Posted July 9, 2019 @Radi Remember the Saturday at g. Skill booth. I showed you, that even your chip can boot up with 1.35 Sa and 4800... Quote

Went up to 1.6. And i.m talking here about xmp 4800c18 not c14. Either you are lucky or me beeing retarded ? Quote
Fasttrack Posted July 9, 2019 Posted July 9, 2019 Very informative and Professional write-up Daniel. Thank you. Folks, it seems I am one of the lucky ones - both my I9-9900K and my I7-8700K boot right up 4800 / 14-13-13-28-2T very tight. 1.375VccIO and 1.425VccSA. Mems on air. Anyway, thanks again Daniel 1 Quote
noizemaker Posted July 9, 2019 Posted July 9, 2019 (edited) tried on a 8700k, can boot (4700 / 14-14) but only with 2.00 DRAM / 1.35IO / 1.45SA. (G.Skill F4-4000C18) my memory sticks are bad Edited July 9, 2019 by noizemaker Quote

Crew Leeghoofd Posted July 9, 2019 Crew Posted July 9, 2019 (edited) Great the profiles are updated now, as someone else mentioned also plz for the X series. Time to rebench Geek and X265 Edited July 9, 2019 by Leeghoofd 2 Quote

Dancop Posted July 9, 2019 Author Posted July 9, 2019 Just look into the g. Skill results. At least you'll find the first timings for this 1 Quote
