overclock a10 7850k GPU - NB voltage and ratio????

[liquidchild101]

hi im looking to over clock my system

this is what i have

HyperX Savage 8 GB (2 x 4 GB) 2133MHz DDR3 CL11 DIMM XMP Memory Module
AMD A10 7850K Black Edition with Radeon R7 Series New FM2+ Kaveri HSA CPU
MSI A78M-E35 Mini-ATX Motherboard (AMD FM2+ A78, 2x DDR3, 4x USB 3, E LAN, HDMI, DVI)


im looking to OC my GPU to get the most out of my PC

ive been looking online and it looks like i need to increase the NB voltage and the ratio (see below)

(http://www.hardcoreware.net/kaveri-7850k-overclocked-benchmarks/)

but i dont know what the safe levels of voltage or ratio to go for

at the moment the GPU is set at standard 720mhz

but im hoping i can get it to about 1020 MHz

can anyone tell me what the voltage and NB i need to do to get it there

ive tried just putting the GPU up to 1020 but found that it black screened so im guessing i really do need to do the ratio and voltage.

just to add. im not bothered by the CPU. its a nice level at the moment. i dont even mind putting it down to give the GPU more power. this build is a cheap gaming pc only.


thanks in advance

See http://www.eteknix.com/amd-kaveri-a10-7850k-overclocking-unleashing-gcns-potential/
"AMD’s Kaveri K Series APUs have a wealth of untapped performance potential: out of the box they come with a modest 720MHz GPU core clock speed, yet anyone who has toyed with AMD APUs in the past knows there’s going to be a lot of overclocking headroom. Before we progress any further I’m going to make my intentions with this article clear – AMD’s Kaveri APU is about the GPU and that’s where our focus lays today. Sure you can overclock the CPU, but because the CPU and GPU are combined, overclocking the CPU reduces the thermal and power headroom of the GPU, and vice versa. Not to mention that the GPU offers the most potential for performance scaling whereas the CPU doesn’t offer anywhere near as much – so picking the CPU over the GPU will leave you with less performance than if you’d have picked the GPU. Picking only the GPU for overclocking also makes sense as the A10-7850K is primarily designed to be a gaming chip, and a chip that takes advantage of GPU acceleration, so overclocking the CPU with detriment to the GPU makes no sense at all. How does the CPU have the potential to detriment the GPU you might ask? Well it is quite simple – the CPU produces more heat and uses more power than the GPU so overclocking it is likely to lead to thermal throttling of the entire APU package. With regards to TDP/power-based throttling you can get around this by disabling AMD’s APM (Application Power Management) but you still have the heat issue to contend with. Therefore for the purposes of this article we’re going with a GPU overclock only. For those interested in overclocking the CPU you’re better off waiting for the standalone Steamroller based Athlon CPUs to hit the FM2+ socket, or going with existing FX and Athlon series AMD CPUs."

thanks for the info. ive had a look at the link and it doesnt seem to give any nb ratio or voltage.

what it does say is that without any voltage tweaks they were able to get it to 1028mhz

the problem i found was when i did it. all my games wouldnt start or crash after the menu screen.

bascially looking like it didnt have enough voltage or what ever to keep it going.


id also like to add that some people have turned off the turbo in the bios when OCing to keep from jumping all over the place

any advice?

 

[i7Baby]

What they are saying is that it's a waste of time to overclock the cpu. That just then overheats the GPU and downclocks the GPU. So no net gain.

 

[liquidchild101]

thats what i mean. i dont want to overclock the CPU. just the GPU

and they said that overclocking the GPU is ok. getting it to 1028mhz

 

[i7Baby]

You overclock the GPU by putting faster ram in. That's all.

 

[liquidchild101]

heres a quote from the article

When you stack fast memory with an overclocked GPU AMD is claiming as much as a 50% boost in frame rates in some games. So with your appetite now ready for some overclocking let’s get straight into the results!

 

[i7Baby]

Yep - as I said, just use fast ram.

 

[liquidchild101]

yes but it says that "with a overclocked gpu" meaning that the gpu can be overclocked. and basically saying in the whole article that if fast ram plus a overclocked gpu will be the best option.

thanks anyways

You should watch this Video:
https://www.youtube.com/watch?v=z0Z7H1PYUkk
This can be one option to increase the performance of the integrated graphics of an APU. You can increase the clock frequency of the GPU that is integrated in that APU. For doing this, go in bios: Advanced Frequency settings>>Graphics clock speed and increase it to some amount from the factory setting. This can also be other method to increase the performance of the integrated graphics.

yeh, i watched that vid already. unfortunately my mother board can only take 2133 ram. and im happy with that. for the price i paid.

ill give the gpu clock speed ago and see where it takes me. but like i said before. the last time i did that. it was unstable. thats why i was asking about the nb voltage and ratio

If you want to overclock your CPU, theny ou have to do it yourself. We cant tell you directly the settings. Even if we have almost same rig I cant tell you the settings. See the correct overclocking method:
I will recommend to do overclocking in bios because it needs less voltage, higher oc and if also increase the processor life comparable to oc by software. Also If you get Any manual settings and of you go for that then the oc will be unstable and will produce more heat. If you give less voltage then you will get unstable oc and if you give higher voltage then it will produce more heat and will reduce CPUs life. So it is important to find a sweet point of correct combination of frequency and voltage. To do that Just follow this Steps:
1) just enable your XMP memory profile if your memory support that.
2) increase the cpu ratio from factory settings a little(whichever smallest possible) and boot in your os.
3) Download cpu stress testing software prime95 and do a stress test around 20 minutes.
4) if it passes then restart and go in bios, increase a little cpu ratio again a little bit.
5) if it passes then repeat 4th method. And if it not passes then go in bios and increase the CPU voltage and again test. Just keep doing that.
6) a time will arrive when the temp will gone so high, at that time you have to stop and keep it to cool.
7) also when doing upper methods you have to keep a eye on your temps.
8) a step will arrive when prime95 will never pass or the temp will gone so high immediately when stress test started, that point you have to stop and you get the unleashed speed of your processor. You got a stable oc now. Watch temps and don't let them go above 80. Also see the guide that I given below, it will tell you the basics. Good Luck.

To get a stable GPU OC, You have to Overclock the CPU.

hi, thanks for the info. ive put the xmp to 2133mhz and tried uping cpu ratio. but unfortunately the bios doesnt allow me to change the voltage. this in turn makes the games unstable and crash.

the best i could get without changing the voltage was 1900mhz on the cpu nb

does this mean that the 2133mhz ram that ive bought is not being used to its full potential?

ill also add that ive tried using amd overdrive but for some reason it just resets when i restrart the system

and ive tried msi afterburner but it doesnt allow me to up the voltage. even when ticking the unlock voltage button

cheers

it seems like im stuck

Cpu and ram are totally different things. No matter what's their frequency. Even if you have your RAM at 2133 mhz, computer will change the frequency according to its need frequently. Don't overclock CPU by any software . Give your bios photos of frequency and voltage pages.

hi, sorry its taken me a while to get back. i do really apprentice the help.

heres the photos of of my bios. as you can see there isnt any option for cpu voltage. and when i click the OC genie it comes up with the 65w apu error

Have you updated your latest bios? I think you have older bios and you have to update it. First check your current version of bios in cpu-z. Check the updates of bios on the motherboard manufacturer's official site. If you have older bios than the updates given at the site, you will need to update that.

hi, i check the bios and i was .1 behind so ive just updated it. but it looks like it hasnt changed anything.

all i got was a reset of my preference. any other ideas?

also, do you think uping my GPU to 1026mhz would be safe? 900mhz is the highest ive gone so far

Check in the CPU features. If you don't found anything that is related to voltage or VCore then finally you can do that is to contact to the msi. Go on their site and go on contact. Send a email about this voltage concern.
About GPU, you can do it, but after increasing the frequency you should test it to ensure it to stable. Download the GPU stress testing software GPUtest here:
http://www.geeks3d.com/gputest/
Do a stress test, if it crashes then you will need to decrease the frequency of increase the voltage. If it passes then you are Ok. Good luck.

hi again, ive talked to MSI and it looks like there isnt any features to change the voltage?!

is there anything i do now. i know its not advisable to change the voltage with software. but would this be a case were its the only action i take? the only other thing i was thinking is that MSI made this board without thos features because it couldnt handle it? in turn, i shouldnt mess around with it with software

if you guys think i can do it with software. which program can i use.

ive used AMD overdrive and MSI afterburner. but they either grey out the voltage feature or reset after changing the voltage.

here the email they sent me back:
