ajdahoPl Posted July 20, 2021 Posted July 20, 2021 Fellas, today I bought a 6800xt liquid devil, I'm playing around with the oc, now I tried to use the more power tool, but after changing the voltage on the gpu to 1200 and the power to 350, the card boots up at 500 mhz what am I doing wrong? i also try Buldzoid metod from YT but anything help Quote

Leave the voltage alone and play with the power PL only nothing else as the drivers detect any little change in MPT and if you go past stock max voltages this will always happen. You need to uninstall drivers and re-install fresh ones and the bug will go away. Edited July 21, 2021 by chispy 1 Quote
ajdahoPl Posted July 21, 2021 Posted July 21, 2021 I know, I read it in the meantime, but thank You , there is one more thing that concern me, namely a big difference between the GPU temperature and the junction temperature, about 25-30'C, when I look through the tests it seems to me that in the testers it would be a difference of 15'C at most, in games on my card is like 48-52'C gpu , junction around 70'C and when I run furmark I have 60-62'C on the gpu and 97'C on the junction, power consumption then shows 380W, because I set it that way and this is my 3dmark score looks OK ? https://www.3dmark.com/spy/21658031 1 Quote

This chips are huge hence the need for lots of thermal paste. This will help maybe with the core temp / Tjunction temps as it should be max around 20c difference and please do not run furmark it's a non realistic virus power load wish does more harm than good. Your score looks good . Quote

Waffl3Ninja Posted July 21, 2021 Posted July 21, 2021 well its been a minute sorry for the delay. was offered a chance to start finishing up some of my course requirements toward my red hat architect certificate. then bombarded with classwork as well as work. will be resuming my oc adventures within the week. with some slight adjustments. and nothing over the top. i decided to take a crack at 3dmark this morning. its nothing amazing. but it's where my starting point is. https://www.3dmark.com/3dm/64059071 only modded the mpt for max power 360w up from 289 and 375 on the tdc.. also random update. turns out that xfx released 2 different versions of the black edition. which somehow i received the higher binned version. which explains a lot as to why my card never shows up bios check either on techpowerup or even 3dmark. my manufacturer never shows up. hope everyone is doing well and sorry again for the delay =) 2 Quote

Crossflashing different bios on different hardware chips ( 6800xt to 6900xt ) will get your card bricked 100% for sure , please do not do that to be safe as it does not work. Quote
ajdahoPl Posted July 25, 2021 Posted July 25, 2021 Never say 100%? and how was it with the radeon vega? I've uploaded from 64 to 56, and I think from 7970 to 7950, but there is always a BIG risk, that's why I ask if anyone here has already done it 1 Quote
ajdahoPl Posted July 25, 2021 Posted July 25, 2021 (edited) guys , yesterday i changed the paste on my liquid devil , the temperature delta between the edge and the hot spot decreased drastically from the original 30-35'C to 17-20'C ,(i also noticed that the block was poorly tightened) , while i dont understand why my oc dropped , previously 100% stable in games was setting wattman clocks min/max 2600/2700 in 3dm time spy, sometimes it would crash, on these settings I did my record 22131 gpu score, after changing the paste despite lower temperatures I will not pass time spy on clock settings over 2550/2650 - that also too much 2500/2600 What could be going on? One thing I noticed is that before changing the paste, with clocks set at 2600/2700 real average clock in 3dmark is 2600 now it is higher 20mhz, but I can not complete test 2, and sometimes even in the first test crashes, drivers also reinstalled DDU in Safe Mode Edited July 25, 2021 by ajdahoPl Quote

Waffl3Ninja Posted July 30, 2021 Posted July 30, 2021 (edited) have to agree with chrispy. only change to my last benchmark and the one i ran just a few minutes ago is the the new driver. I was pretty reluctant but Im happy with this one. im going to read up a little bit more. just waiting on documentation from XFX because apparently aside of the scu numbers there is a huge difference between the two XFX black editions. i ll link the two. has to do with one having more efficient vrms and being able to hold a higher voltage.. https://www.3dmark.com/3dm/64342155? holy shit i stand corrected. there are now 3 black edition variants. just did a quick copy paste edit. my contact at xfx kinda leaked but he didnt lol. no officially at least. he said the limited black editions were originally supposed to come watercooled but their was a backorder on the gpu waterblock plates and those went to the asus cards instead.(all speculation tho) maybe i can get some help if some of you on here have the other two. i have the limited black edition. need some simple benchmarks and numbers on the other two. just so i can put together a proper review of sorts. thats the update tho.

chispy Posted July 31, 2021 Author Posted July 31, 2021 Just playing around ( not optimized or serious benching , just testing ) for a very short time with CrossfireX 2x rx 6900xtxh on air stock cooler , one ( Red devil Ultimate ) and one ( ASRock OC formula ) on water , very high ambient temperatures over here summer time ? , not much i can do about that but got me number 4 Global in the Hall Of Fame over at UL/Futuremark in Timespy ✔️ 1 1 Quote
buildzoid Posted August 17, 2021 Posted August 17, 2021 mod location for the 0.75V rail on the red devil cards. This might help with cold behaviour. Stock resistance is around 2K to GND and 0.75V so you'll want to use a 20K or larger trimmer. 2 1 Quote
Butanding1987 Posted August 18, 2021 Posted August 18, 2021 I hope you can resurrect your 6900 XT. Quote
buildzoid Posted August 19, 2021 Posted August 19, 2021 I tried upto 0.95V on the 0.75V rail before the card died and as far as I can tell raising 0.75V doesn't help overclocking at all. So don't bother with that mod. 2 Quote

Splave Posted September 20, 2021 Posted September 20, 2021 (edited) WB edition is nice for OC, since you dont have 2 million screws to remove like air cooler Elmor is working hard on a direct voltage control for 6900XT fingers crossed if you dont have an EVC yet def grab one.

Waffl3Ninja Posted October 1, 2021 Posted October 1, 2021 i have to give up on my endeavors lol. after doing this the hardway only to have xfx dick the limited black edition owners with an unlocked gaming black edition. wtf lmao. never seen so many black editions in my life. literally same card except the newer one kicks the usb-c port for another display port and +200 cclock. i admit that i fell rather full force on my face at my attempt to benchmark and everything. looks like i may need to take a step back read up a bit more. sorry guys. =( Quote
