I think it's the board since I've tried different CPU's and both sticks seem to clock the same plus I could run higher frequency in the past then I currently can and the board gives me debug codes that aren't normal for mem clocking and only happens when mems are in outer slots

 

Would be awesome to see but a big factor of allowing to run 2800 in any benchs is nb volts around 1.3v or lower which is going to limit your gpu clocks

 

Don't you have 2666 c11 dom plats which are likely hynix mfr? If so give them a try with stock nb volts and also see if single channel allows you to clock higher

 

I am too a little suspicious of board as i had ga-f2a88x-up4 in the past and was stuck at ~ 1300MHz in dual channel on it (didnt try single channel) , right after switching to A88X-PRO immediately gained around 30MHz (with same dom 2666 c11 kit and 3 different apu's from 7400K to 7870K) and with help of cold ambient air with fan blowing on them another 30MHz , dont know what magic asus done to those boards (A88X-PRO and Crossblade Ranger) but they seem to really work well with my memory Also in my case a big factor seems to be VDIMM voltage , for some reason either memory or mem. controllers in my apu's hating VDIMM over 1.60v , with 1.60v its reaching maximum clocks (from 1356 to 1368 if lucky but later being not very stable , once even completed GT1 from 3dmark at 1380 but froze in GT2 lol ) and with anything over 1.60v - only ~ 1320 (but can tighten Cas from 11 to 10 , thats not helping much though to compensate the loss of MHz)

 

Another interesting detail i noticed on my 7400K and 7870K is how easy they both handle memory overclock with very low NB volts , both will do 1320 @ Prime Blend stable for over an hour with thei VID NB , 1.1375v !!! NB for 7400K and 1.225v for 7870K . All that leads to strong suspicion that its mobo+ram combination (mutual love if to say like that lol ) that is to thank in the first place for good overclocks

Why do you think its not running in dual channel close to those speeds ? Both memory sticks perform that well in single channel but not so well when in dual ? I found old screenshot from my BCK0 Samsung , unfortunately its single sided so its useless for Kaveri

If i am not mistaken thats without tesselation disabled , hence about 90-100 points lower than it should be . Also didnt bother with subtimings , probably another ~ 100 points missing from there If somebody could find DDR3-2800 capable dual rank set that would make for some monster scores

newlife Same thing , AIDA works fine , only GPU-Z is giving hard time

 

Just checked on Trinity - AIDA also works great , even shows the current GPU clocks , and all other information . Wondering if we can use it instead of GPU-Z (because its not working) on Kaveri and Trinity with Win XP ? In my case even Trinity hangs on GPU-Z load under Windows XP , only way to fix it that i found so far is disabling HPET in BIOS (on Gigabyte boards they have such option in BIOS ) and Asus boards do not have such option sadly .

 

[Kaveri 3DMark social club :)]

newlife and everybody , guys ... i need your wisdom please ! This is driving me insane

 

for past couple days i've been fighting with GPU-Z on Windows XP , the GPU-Z wont open/load completely on my Asus boards (A88X-PRO and Crossblade Ranger) with Kaveri and even with old Trinity APU's ! Tried a whole set of drivers from Catalyst 12.8 to 14.4 , a whole bunch of different GPU-Z versions from 0.6.5 (first to support Trinity) and up to 0.8.6. Nothing works ! GPU-Z just hangs on load (but not freezez completely - can be closed from task manager) . Cant even get it working on an old A6-5400K ! In the same time if i add a discrete graphics card it works (both AMD and nVidia) , tried with GTX 550Ti and Radeon 7870 , GPU-Z works fine on both , in case with Radeon 7870 even with same exact drivers ! This is insane !!! So after couple reinstall's and many many hours spent battling with GPU-Z i decided to try it on my entry level Gigabyte board (some A68 model ) , and same thing , GPU-Z not loading ! Then after googling some more , found a mention about GPU-Z not liking HPET timer for some weird reason . And here we go , indeed after disabling HPET timer in BIOS on Gigabyte board GPU-Z now works on A6-5400K ! And of course by Murphy's law , theres no such option to disable HPET timer on both Asus boards ... But why would GPU-Z not load with iGPU but loads just fine with Radeon 7870 with exact same drivers and OS and rest of hardware ? Everything else's beside GPU-Z is working great , including 3DMarks , just GPU-Z giving me such hard time for no reason , all that described is on Win XP , on newers Win7 and 10 all is fine of course

[Kaveri 3DMark social club :)]

newlife very very nice !!! And good graphics core on that 7650K , 1329MHz with iced water ! :celebration:

 

How much voltage did it need for that ? My 7700K needed 1.65v NB in BIOS (~ 1.60 by multimeter readings) for just 1263 with -5C ambients

 

btw , how to comment on someone submission ? Only see the "like it" button , but how to leave comments or questions ? Lol cant find that otion for some reason )))

[Kaveri 3DMark social club :)]

newlife 1440MHz on GPU - thats first time to see such numbers on Kaveri , very impressive ! And the score is with only DDR3-2400 , just noticed , would of smoked everything 3D if not for memory overclock issues !

 

flanker is Win XP still best for Super PI 32M ? So far only tried it once on Win 7 and got horrible result times in comparison with others , without The Stilt's tweaker program "BullDozer Conditioner" though , so far the personal goal is to get to under 12 min and learn how to run it efficiently And also to figure out how to make GPU-Z display graphics adaptor info under Win XP so to have some fun with older 3dmark's in most "efficient" way , newer GPU-Z version's just freeze on loading (and will only close from task manager) and the older that dont freeze (GPU-Z 0.7.5. and older if not mistaken) wont display the GPU information properly

[Kaveri 3DMark social club :)]

newlife best of luck with that 5.2ghz water 7650k , hopefully it scales well with cold :celebration: Will be awaiting results with great interest !

 

I am also thinking about trying my already delidded 7400K with DI soon , not having big hopes as it only does 4.6 stable on Noctua NH-D15 (room temps) though but will see

 

filmbot just had a memory flash about last benching with 7700K and one interesting detail caught my attention , not sure why and whats causing it , but enabling C6 mode gave a couple hundred extra MHz on it , noticed it before with A88X-PRO and now same thing with Crossblade Ranger . I dont know if you tried it or not , just thought to mention it just in case

[Kaveri 3DMark social club :)]

filmbot The Mr. Squirrel the overclocker is now a regular visitor , ever since winter i started giving the birds some seeds and stuff and he joined the buffet ( poor birds cant get no food because of greedy squirrel now lol ) , i am very surprised of how clever they are . For example , as you can see theres a glass door to the porch , and while its closed the little guy will keep on eating even if i am right by glass watching him , squirrel is just watching me back while eating , the squirrels are not that dumb that we think of them lol

The moment i open the door , he grabs a piece and runs away with it , eats everything from seeds , bread , apples and even bananas ROFL

 

Anyways ... sorry for off topic hehe

[Kaveri 3DMark social club :)]

The Stilt Thank you so much for sharing some light and knowledge about upcoming architecture and about the reason behind AMD Overdrive timing option issues , and for all wonderful tools you've given to us ! :celebration: That was most interesting and educational read !

 

If the 17h happens to exceed my expectations and the other issues can be solved, then I have no issues in supporting the platform in the same way I have done in the past.

Best news ! Lets hope AMD delivers + new tools will equal as best times and generous gift for lots and lots of enthusiasts !

 

P.S. attached some funny photos from last benching with Kaveri , looks like the little guy is into benching too , i already bought him(or her lol) some nuts so dont worry about bread hope those photos bring a smile and good mood to everyone

newlife Thank you , m8 ! :celebration:

 

Have you seen my helper ? I will post some pictures

[Kaveri 3DMark social club :)]

I love APU and i think this is a good start to bring it to the community again.

 

:celebration: Indeed its an extremely fun to play with toy , those APU's , and hopefully judging by rumors , more fine toys to be out soon , just saw some news about 7890K to be released very soon and whats really exciting maybe even AM4 based excavator apu's later on . That will give us something to play with until Zen is out hehe

[Kaveri 3DMark social club :)]

I was fairly disappointed with CPU mhz too but I also didn't work with vcore yet either. 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

 

Dont give up yet m8 :celebration: , just need to figure out whats holding up the score and you are good ! Definitely not the cpu clocks (as they dont help much with overall score at all might just drop them for now until you get good scores and only use max for final run to boost 10-20 or so extra points ) , you got great gpu clocks , decent ram speed already . As Newlife already noted and judging by high score results from database most are using Win10 for kaveri 3dmark2013 runs , you might want to get Win 10 installed , in my case for example it boosted the score by a good 50+ points vs Win 7 ! And silly question - did you disable tessellation ? It is hard to tell but just in case you forgot to disable it you can count on another 90-100 "free" points

 

P.S. i dont know what IC's my memory got (its a pain in the ass to remove heatspreaders from dominator ram's ) , but seems like its a Hynix based kit . The only samsung's i have are single sided ones (unfortunately) that give poor efficiency/scores because of being sigle ranked despite insanely high clocks

Thank you so much guys ! :celebration: i got very lucky with that 7870K - everything is good about it , great cpu cores , great IMC and great iGPU and the best part its the first one i bought and got the "good one" first try hehe Will definitely play with it later on again , perhaps with dry ice next time :celebration:

[Kaveri 3DMark social club :)]

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 ..

[Kaveri 3DMark social club :)]

newlife

 

Very nice score m8 ! :celebration:

 

Dual Graphics look at that +50% performance boost , not bad at all ! Always wanted to try it (dual graphics) , thank you for showing us .

[Kaveri 3DMark social club :)]

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 ! Strong Memory controller on this 7400K

[Kaveri 3DMark social club :)]

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

[Kaveri 3DMark social club :)]

DDR3-2800+ on Kaveri ? No problem with Asus A88X-PRO + Samsung BCK0

But thats single sided RAM's , so of course much lower efficiency compared to ~ 1350 double sided --> Dominator's Platinum 2666C11 (CMD8GX3M2A2666C11)

 

Yet shows the great potential on memory oveclocks

 

[Kaveri 3DMark social club :)]

windows 10 in ide ?

 

what voltage for 1.2v apu ?

 

Windows 10 in AHCI ! It had problems installing with high FSB (would not detect HDD/SDD) but after installation with 100 fsb and loading fresh AHCI driver started booting with high FSB (not sure how high but tested with up to 117 and worked well) , also some of my SSD's would not work even after AHCI drivers (errors during load and windows attempting to repair) , the good old sand force ssd with Microcenter label (lol) worked and so did WD 1TB "blue"

 

Asus A88X-PRO is very good for memory oveclock , i've tried same CPU/RAM with Gigabyte GA-F2A88X-UP4 and could not get anywhere even close to RAM overclocks Asus did , maximum was 1296 with UP4 for me

 

 

 

[Kaveri 3DMark social club :)]

Most likely done with "air" runs for A6-7400K

 

A6-7400K

Noctua NH-D15 with ambients around +1 C ( 35F )

Asus A88X-PRO , BIOS 2301

2x4Gb Dominator 2666C11

 

VDDNB = 1.70v , VCore = 1.425v , VDDR = 1.60v

 

Modification of Tesselation only for Fire Strike (Fire Strike not Fire Strike Extreme and Ultra ) and Unigine Heaven Basic and Xtreme . Rest with default drivers settings (with Performance slider) .

 

3DMark Fire Strike : 1692

3DMark Fire Strike Extreme : 773

3DMark Fire Strike Ultra : 399

3DMark Sky Diver : 5439

3DMark Cloud Gate : 5605

3DMark 06 : 11269

3DMark 05 : 18409

3DMark 03 : 32301

 

3DMark 2001 : sadly could not find a GPU-Z version to report correct name for Kaveri iGPU part in Windows XP with old Catalyst drivers that work on XP and no point running it on Win7 , very very sad to see it abandoned

 

[Kaveri 3DMark social club :)]

Delidded my A6-7400 today which resulted in 17 degrees drop under load with 1.55v

 

[Kaveri 3DMark social club :)]

gradus Big people i see ! How is life ?!

 

Awesome efficiency and memory clocks! You know now I'm going to have to try again with that cpu

 

:beer: and cheers , sadly it looks like no one loves the little guy 7400K but 2 of us on hwbot lol . So lets give it some love i say ! I am quite determined to push that thing further , much fun so far !

 

Update : cold has not arrived yet , only +10 C outside , will continue tomorrow , it is expected to hit around -2C . Yet that drop of only 15 degrees (compared to indoor +25) was enough to push the graphics part to the next level with VDDNB = 1.70v

Wonder how high will it go under LN2 ?

 

[Custom country flag BIG issue]

I was playing with country flag and clicked on to add custom flag from image out of curiosity , now when i try change countries it wont display any default flags at all next to my nick name . Very frustrating as cant even participate in country cups or location based activities like that . If a kind mod/administrator can help and maybe reset my profile back to normal so country flags to be displayed again i would be very very grateful and will never touch the unknown things in settings again

 

Please help somebody Thank you

[Kaveri 3DMark social club :)]

A6-7400K looking good so far

 

[Kaveri 3DMark social club :)]

nice ! how much volt for the gpu ?

 

had to give it VDDNB = 1.6375v , not a very strong gpu unit on that 7700K

 

I could it try quickly:)

 

Unleash the power of God-avari !

 

Here's a couple of runs I've done

 

Very nice on both m8 ! Especially i like the 7400K as i have one myself and planing to play with it this weekend , cold weather on the way and no longer hot outside - its a crime not to use such rare opportunity !
