Gorod Posted December 3, 2015 Author Share Posted December 3, 2015 How did you set in in BIOS? What kind of voltage ? I only touched those shown on BIOS screenshot ))) P.S. A10-7870K has arrived , also Crossblade Ranger ! Have big expectations ! You mean 1.2vAPU or VDDNB? What does VDDA control? I dont know what VDDA controls but in my case it helped a little bit with CPU overclock with 7400K , at least +100MHz on CPU clocks . Maybe someone can explain what those 2 voltages are for i have no clue Quote Link to comment Share on other sites More sharing options...
Gorod Posted December 3, 2015 Author Share Posted December 3, 2015 (edited) Not very happy with CPU overclock , stuck at only 4620MHz @ 1.5875v , 4700 not possible even with much higher vcore not even bench stable And temperatures as you can see in AMD OverDrive are very good Also some observations on how 7400K reacted and scaled to voltages (if anyone interested that i doubt considering its Very low end and cheap APU lol) , all results Prime stable (time is just how long i left it to run) : CPU MHz : 3500 MHz @ 1.1375 vcore --> Prime stable 8h13m , Temp margin remaining = 67.2 C (in AMD overdrive) 4000 MHz @ 1.30v --> 6h14 , T marging = 60.2 C 4200 MHz @ 1.3625v --> 10h17m , T margin = 58.6 C 4300 MHz @ 1.40v --> 6h51m , T margin = 55.4 C 4400 MHz @ 1.4625v ---> 5h2m , T margin = 52.4 C 4500 MHz @ 1.50v --> 30h19m , T margin = 47.6 C 4600 MHz @ 1.575v --> 6h47m , T margin = 44.9 C 4620 MHz @ 1.5875v | iGPU @ 1.425v + Furmark --> 9h46m , T margin = 38.1 C iGPU o/c : 900MHz @ 1.1375v NB 960MHz @ 1.20 1029MHz @ 1.25 1108MHz @ 1.35 1200MHz @ 1.475 *** gpu LOVES to stay cool , huge increases from temperature drops Memory o/c : Tested from 1200MHz all the the way up to 1320MHz prime stable with just 1.1375v NB !

newlife Posted January 4, 2016 Share Posted January 4, 2016 Decided to give the 7650ka try and not bad for such a low priced cpu which i could valid at 5.22ghz with a h100 http://hwbot.org/submission/3085047_ Also tried dual graphics with a R7 240 gddr3 2gb Quote Link to comment Share on other sites More sharing options...

Gorod Posted January 7, 2016 Author Share Posted January 7, 2016 Massman Thank you for not forgetting about "red" underdog AMD still holding the last stand in APU's department and many innovations intel lacks ))) newlife Thank You for help pointing on importance of subtimings m8 , it really helped a lot ! cheers ! P.S. Does anyone know a software utility for changing memory timings/subtimings that work on Kaveri ? For some reason AMD Overdrive is acting weird , for example after i change any of subtimings the scores in 3d mark drop a good 100+ points , no matter what i change , once i hit the "apply" button performance drops . And seems there are no other utilities for playing with timings , searched on internet entire day and could not find anything .. Quote Link to comment Share on other sites More sharing options...
filmbot Posted January 7, 2016 Share Posted January 7, 2016 Just leaving this here for you guys. 3DMark Fire Strike - Kaveri Leaderboard //table 3DMark Fire Strike - Godavari Leaderboard //table Thanks a lot for this. What is the main reason Godvari is significantly better than Kaveri? Better IMC? Quote Link to comment Share on other sites More sharing options...
newlife Posted January 7, 2016 Share Posted January 7, 2016 (edited) Godavari are meant to be a better bin but the two cpus I've had are junk on cpu core and the ihs is soldered which makes a big difference to the volts you can run but with the two cpus I've tried don't run well under cold and one cold boots at -30 and the other -40 while my 7400k cold boots at -80 and cb at -100 Edit: the only thing I know of that allows changing timings was AOD but I had a lose of efficiency with richland when I did 32m Edited January 7, 2016 by newlife Quote Link to comment Share on other sites More sharing options...
Massman Posted January 7, 2016 Share Posted January 7, 2016 I don't think AOD even supports Kaveri. //ninja-edit: apparently the latest version actually does! The Stilt used to support AMD with enthusiast-grade software, but I don't think AMD is too bothered. Haven't heard of any recent tool that support the latest architectures.

And sends my system to BSoD while tweaking RAM timings. Also, looks like latest GA-F2A88XN-Wifi BIOS version F6 breaks IGP overclock (stays at stock no matter what MHz are set in BIOS).

Also, looks like latest GA-F2A88XN-Wifi BIOS version F6 breaks IGP overclock (stays at stock no matter what MHz are set in BIOS). You must be setting something not stable because it works fine for me and I'm using a F2A88X-UP4 and was fine on the F2A88XN-Wifi as well My F2A88XN-Wifi died so I cant comment on the f6 bios but f5 works fine and have you tried overcloking using AOD? Oh and I had a problem once with the UP4 were it would run igpu stock unless done in OS but a clear cmos fixed that Quote Link to comment Share on other sites More sharing options...
devl547 Posted January 7, 2016 Share Posted January 7, 2016 You must be setting something not stable Even minor memory subtiming change leads to BSoD. And setting that timing through BIOS is fully stable. My F2A88XN-Wifi died so I cant comment on the f6 bios but f5 works fine and have you tried overcloking using AOD? Actually, I reverted back to F5. AOD overclock disables freq drop on idle, so it's useless for me. While Gorod uses Kaveri as pure benching platform, I prefer more stable daily usage OC like in old days but a clear cmos fixed that No luck for me. One small question - are there any F2A88XN bioses with more settings unlocked (like in UP4)? Quote Link to comment Share on other sites More sharing options...
newlife Posted January 7, 2016 Share Posted January 7, 2016 I have a non public extreme bios that unlocks memory volts and nothing else and the A88XN-WiFi was as good as the up4 for igpu stuff without the secondary volts and is better at clocking memory Quote Link to comment Share on other sites More sharing options...
flanker Posted January 7, 2016 Share Posted January 7, 2016 can someone try max SUperpi32M at Kaveri? Someone with LN2? If some chip can hit 6 GHz 32M, it could be really quick (under 10min) Quote Link to comment Share on other sites More sharing options...
bboyjezz Posted January 7, 2016 Share Posted January 7, 2016 Thank you for not forgetting about "red" underdog AMD still holding the last stand in APU's department and many innovations intel lacks ))) Oh noooooo, my Godav FS score for CC 2015 is beaten already... Just saw this post today.. Thanks for making this thread, Gorod! I love APU and i think this is a good start to bring it to the community again. Good run anyway, so efficient!

If some chip can hit 6 GHz 32M, it could be really quick (under 10min) I did but was only a quick run and should've been good for about 5.7ghz 32m but run out of time because I had country cup stuff to do http://hwbot.org/submission/3059804_ Was going to try my 7650k under dice today or tomorrow that I could valid at 5.22ghz with a old and poor shape h100 and 5.32ghz with ice water and 5.126ghz 32m with ice water http://hwbot.org/submission/3079267_ Quote Link to comment Share on other sites More sharing options...
flanker Posted January 8, 2016 Share Posted January 8, 2016 I have 860K Athlon and I got 6 GHz. But not saved validation file....Maybe next time, cause I had not much LN2 (maybe 5l only for benchamrking ) 6016 for short time Quote Link to comment Share on other sites More sharing options...
filmbot Posted January 8, 2016 Share Posted January 8, 2016 Phase strapped to the 7850K last night, finally got some decent speeds. Will post some scores tonight or tomorrow. Also have a Kabini setup with EK waterblock that I may fire up Quote Link to comment Share on other sites More sharing options...

filmbot Posted January 9, 2016 Share Posted January 9, 2016 Seems this is a very, very average chip as it took strapping on the phase unit to match air cooled scores. Think iGPU core is tapped out but feel there is room for improvement if I had RAM with ICs better suited for AMD. No tweaks, just new OS and raw speed. Hopefully now that I have baseline, I can maybe break 23xx. Quote Link to comment Share on other sites More sharing options...

Hopefully now that I have baseline, I can maybe break 23xx. Not bad on the gpu side but the cpu side is shocking and aim for 24xx because at your speeds it's definitely possible Edit: Sammy's are one of the best ICs for AMD although hynix will clock better and keep in mind I've been using PSC which is extremely painful to run with AMD especially with kaveri/godavari Edited January 10, 2016 by newlife Quote Link to comment Share on other sites More sharing options...

Basically just maxxed and ran what would run. Plan on trying to lower vCore and see if decrease in temps allows for more headroom. Regarding ICs, I was going off what Gorod said and seems likely that's why he can hit 2666+ speeds. I'm gonna break it down tomorrow as my testing today seems there's nothing else that I can test to give a significant boost. Might switch to either 8150 or Kabini. AMD is much easier to play than Intel at the moment Quote Link to comment Share on other sites More sharing options...
