Upgrading CPU on HP 828a motherboard

[thomwwar]

Hi peepz,

I have a hp 828a motherboard.
I'm running a Intel i5-6400 cpu and gtx 1070 gpu on it atm.

I want to upgrade my cpu and my question is, what cpu's can i run on this motherboard..
Able to replace the i5 for any i7 or maybe even the i7 8700k?

Or do I have to buy a new motherboard too?

Thanks for the help!

No, you cannot. You can only use Skylake i7 CPUs, 6th gen. I do not see that there has been a bios update to allow running 7th gen CPUs on that motherboard and no 6th or 7th gen motherboards support 8th gen Coffee lake cpus like the 8700k.

If you have the latest bios version installed, and you will need to check that, then you MIGHT be able to install the 6700k, otherwise the highest upgrade it supports is the i7-6700 non-k sku. You should verify with HP about support for the 6700k before purchasing any upgrade though.

Motherboard supports the following processor upgrades:
Processor

TDP

Integrated Graphics
Intel Core i7-6700K (Skylake) 4.0 GHz Quad Core (only with Ariia+)

91 W

Intel HD Graphics (GT2)
Intel Core i7-6700 (Skylake) 3.4 GHz Quad Core

65 W

Intel HD Graphics (GT2)
Intel Core i5-6400 (Skylake) 2.7 GHz Quad Core

65 W

Intel HD Graphics (GT2)
Intel Core i3-6100 (Skylake) 3.7 GHz Dual Core (only with Hal2)

51 W

Intel HD Graphics 530

Thanks a lot for your reply, really appreciate it!

One more question, I got the same chassis as this one: https://ic.tweakimg.net/ext/i/2001360343.jpeg
(Called: hp omen 870-130nd)

If I choose for another motherboard which one would be good enough or which one would be perfect for the i7-8700k and my gtx 1070 and will fit in the above chassis?

Thanks in advance!

I would need to know what case model that is. I don't know what it is just by looking at it. There are too many cases out there for anybody to automatically know that. If it was a mainstream common model, I probably would, but that case I do not. If you can get back to me with the case model I can find out for you. I will also try to identify it. It's likely that it's a micro-ATX form factor, but knowing for sure would make all the difference.

Ok, that is a micro-ATX motherboard and the case supports graphics cards up to 7 inches long.

Are you wanting to be able to overclock the CPU?

Not planning on overclocking it right away, but maybe after some months I change my mind and want to overlock it.

One more question, If I choose the i7 6700, will this be good enough to stream 1080p with my gtx 1070?
(Couldn't find a good answer on that question, some are saying yes and some saying no haha)

Are you planning to stream WHILE gaming or doing other tasks like encoding and streaming on the fly, or will streaming be the only thing happening while it is doing so? If you are going to be doing heavy multitasking like streaming or encoding, ripping, or other demanding tasks, you might really want to consider a change to the Ryzen platform.

Not only would it offer better multitasking performance, it will likely be less expensive as well.

If you just want to stick with what you have now and upgrade that, then yes, it should be able to do that although it's clearly not going to do it AS WELL as a newer configuration that has more cores/threads and at least minor improvements in IPC plus support for AVX and other instruction sets that are not supported on Skylake.

Personally, I'm using a 6700K OC to 4.5Ghz and so far there has been nothing I have not still been able to do with this configuration, but it's likely I may upgrade at some point after the 9th gen CPUs are released if they look promising. Those are "supposed" to launch at the end of September, but the last Intel launch, which was Coffee lake 8th gen, happened, and then CPUs were not readily available for several months afterwards due to a lack of Intel being able to actually produce them in quantity. So it could be longer.

I think it really matters WHAT exactly you want to do with it, and what you want to invest in being able to do it.

Thanks again for your great answer, you're really helping me out!

About streaming.. I'll only use it for gaming and streaming at the same moment, so for example I'm playing pubg and streaming on twitch (with obs) at the same time. And definitely prefer streaming at 1080p/60fps with a clean stream which is not buffering and stuff.

I did some research and couldn't find anything about running a 7th gen cpu on the motherboard I'm using atm.
If I buy for example an b250 or z270 motherboard, which cpu's are compatible with these motherboards?

 

[Darkbreeze]

That is because this is an OEM motherboard and HP is likely too lazy or cheap to release a bios that would allow users to run a 7th gen CPU on it like the aftermarket motherboard manufacturers do. Plus, that would cut a lot of upgrades out for them from customers who upgrade every cycle because why upgrade the whole PC if you can just add a new processor.

If that were an ASUS, ASRock, Gigabyte, MSI, EVGA or Intel motherboard, you would be able to use any 6th or 7th gen CPU in it even though it was meant for 6th gen only at the time it was released.

If you bought a Z270 motherboard, an aftermarket model, then you could still use any 6th or 7th gen CPU. The difference is, you wouldn't need to have a previously compatible CPU first, like you would with SOME of the 6th gen motherboards, in order to update the bios first to support the 7th gen models. Unfortunately, I do not see that there are ANY bios updates for that motherboard, but if there are, perhaps hidden behind a support paywall somewhere, then it's possible they might have offered that via bios update on that board too but I seriously doubt it.

At this late stage in the game I think it would be a waste to spend money on any 6th, 7th or 8th gen CPU or motherboard unless you are able to get it new for 75% or less than normal retail price, or used for less than 50%. 9th gen Intel CPUs are "supposed" to be coming at the end of September, and while we've seen paper launches before from Intel, we're really hoping that won't be the case this time with AMD gobbling up market share like a Langolier (Google it if you don't read Stephen King books).

Well, "hoping" might be too strong a word. It's good for AMD to be competitive again. Keeps both camps a lot more honest.

Honestly, for what you want to be able to do, ALL of the benchmarks and comparisons for CURRENTLY EXISTING products points to AMD Ryzen CPUs doing the better job of simultaneous gaming while streaming thanks to having very close to the same IPC as Intel but offering more cores at any given price point. That might change with the 9th gen Intel offerings, but we don't know a lot yet, or when they'll actually be able to be purchased. All we know is that "maybe" at the end of September they'll be launching. Since no Z390 boards have released yet, I'm not pushing the idea that it will be this month, but it could be October. Certainly before the holiday shopping season I'd think.
