Cpu upgrade. Can I put 9700k in.

[imginy]

Hi guys,

I wanna replace my i5 8400 with something faster.

My board is a z370 aorus gaming 3 can I drop a 9700k/9700kf straight in here?

I have been looking at 8700 8700k 9700 9700k 9700kf. They all seem to be around same price £300, only about £20 difference between different models. I guess 9700k or kf would be the one to go for as long as my board can handle it.

It will support all those CPUs so long as you update bios to the latest.

Ok thanks for confirming that.

Also any idea what sort of clocks my board could handle with a 9700k? It was a fairly cheap board around £130 just wondering what I should set the core speed at.

Oh nice one guys thanks and yeah it is just for gaming (1440p 120hz)

I will grab a 5800/5900xt to put with it later in the year.

Make sure to avoid any old stock of 9700K, they are the older stepping of P0, you want the newer silicon which is R0.

Not sure what I will be getting.

I have ordered a 9700k but had to order from abroad as couldn't see anywhere in uk still selling them around the £300 price they were before Christmas.

I was going to get the 9700kf from ocuk but price has gone up.

Does it make much difference what one I get?

Without Hyperthreading you will have temp headroom so oc the hell out it.

I look forward to clocking it up but for now it will be mild OC.

I just have a small/medium size air cooler on there right now so will be using that for the time being.

I have a big phanteks but that is still on my old ivy bridge and is a pain to fit.

I guess I will end up putting one of the all in one water coolers on at some point.

The 9700k/kf is probably the best one for your motherboard as there will be less strain on the weaker VRM's.

I used the same motherboard as you and with a 9700k R0 and could do 5.2Ghz though it needed 1.32v and the VRM's were running a little toasty under load so you should monitor those temps with HWinfo. Decent case cooling can help in this regard.

That's good news then. I do a nice big case , I think it's a called a coolermaster master case.

Once I get a new cooler I would be very happy with 5ghz all cores. That should last me quite a few years gaming before I need to upgrade again.

When my 9700k turns up what should I set my voltage and clocks to?

My current cooler is just one of these little pure rocks. https://www.overclockers.co.uk/be-quiet-pure-rock-cpu-cooler-120mm-hs-010-bq.html

I will probably get a decent all in one water cooler for it at some point but for now I haven't got the money to get one.


@Phil2008 that's a nice looking rig

When I over clock my cpu I firstly set the cores at a little lower to what speed I want them to run at and if temps are ok under stress I then slowly put them up to what I want them to run at.

Then comes the tedious bit. I begin slowly turning down the cpu volts untill cpu fails when stressed or windows crashes/hangs. Then I increse the cpu volts untill intel burntest or whatever stress program Im using use runs for about 10mins without failing. Then when I have done that I run the stress program for 12/24 hrs and keep fingers and toes crossed that it dont fail and if it does, increase the volts a notch, then try again with the stress program..

If you do it the long and boring way,, the cpu will run at the least amount of volts as possible and run as cool as possible too. Not to mention You'll have a rock stable cpu that will be up for anything you throw at it.

I hope all that makes sense....

Ah yeah,, I disable turbo boost aswel and left the power saving features on in the bios, because then when the cpu is at idel or not doing much the clock speeds are automatically turned right down, then as soon as the cpu does work, the clock speeds shoot back up to your clockspeed settings

Idel

Load

Other than adjusting the cores clock speeds, cpu volts and disabling turbo boost, I leave everything else alone in the bios.

To be honest I don't wanna do it the long way.

Can someone just give me suggestion of what voltage I can use with my cooler? (£30 pure rock)

Then I will try 4.7 and if that works I will try 4.8.

Start with 1.30v manual, constant voltage (you don't really want to go higher than this). You should be fine starting at 4.9Ghz but you can start lower if you want. Get Realbench 2.56 and use the stress test for 15min initially, at the same time have HWInfo64 sensor readings running and find the VRM readings and CPU temps (use 'CPU Package')

CPU temp should stay less than 90c for this. VRM temps should probably be at least 10c lower than CPU temps on z370. Adjust voltage down if CPU/VRM start to exceed this.

It's also good to get a baseline and running Realbench with everything at stock and seeing what max CPU/VRM temps you get and the stock voltage.

Also set LLC to Turbo. You can leave pretty much everything else at Auto. Good luck.

Perfect thanks

Ok no problem. When I get a new cpu the first thing I do is overclock it and get it running the best and coolest that it can, At the end of the day you shouldnt need to touch the overclocking again, so you might aswel spend time getting the settings bang on right, unless you need your pc for work and cant aford any downtime.

1 thing I would do is backup your windows boot drive if you can, incase widows get corrupted while your overclocking. It has happened to me many times while overclocking with a unstable cpu.

I just don't want all the messing about.

I will just do what martin said and set it to 1.3v 4.9ghz/4.8 run a stress test and check temps and then go play overwatch or something.

 

[imginy]

Yeah I must remember to update the bios before I pull the old chip out.

Thanks for telling me which version.

 

[imginy]

Thanks for the help guys.

I got the latest bios and stuck the 9700k in there yesterday and everything went smoothly.

I booted up and motherboard had automatically set everything for me it's at 4.7/4.8 and temps are fine and it's playing games fine so I'm not going to change any bios settings my self.

On hardware monitor it's at about 1.25v and highest temps i see while gaming were 50's.
