What motherboard have u all went for ?

My 3900X is due to arrive tomorrow - had to get the delivery rescheduled. Will be putting it into my existing Gigabyte X470 Aorus Gaming 7 motherboard.

Gigabyte are great at getting updated AGESAs out

Now the prices have fallen back to normal, I will be looking at getting one of these. My trusty 2500k rig is really suffering in games like COD.

That would be a great upgrade from your 2500K. One of the good things is that you do can pair it will a ~£100 MSI Tomahawk Max and still get stellar performance out of it.
It's more important to get good memory and for that some Crucial Ballistix Sport LT 3200 MHz C16 stuff is ideal and is currently going for £65 for 16GB. This will clock to 3600Mhz C16 quite easily which is the minimum you should be aiming for. There's a thread about it here in the Memory forum.

amazing the difference voltage makes to the performance, at 1.4v on memory i get 300 points less than at 1.35v on cinebench r20

How would having the voltage higher give you less points?

I have found RAM speed on my system has no effect on results. (3200/3600 CL 14)

Same, not noticed any differences

I dont know, but ive gone back and forth a few times and tried it and it does.

Looking forward to getting this bad boy installed

Yes, I have been keeping an eye on what's what type of thing. Same board, I recommended to my friend, as the first attempt with these chips kinda failed. Thanks for the tip with the ram as that's really really cheap

This is motherboard/bios dependent. On two motherboards I've had lowering the voltage using the offset method resulted in significantly higher CBr20 multithreaded scores, one as low as -0.1v offset. (Also lower temperatures) Though in a third motherboard it would decrease scores.

Temperature causes reduced boost speeds so dialing down volts can reduce temps and allow better boosts.

I haven't tried this yet but will do some benches later today.

I see Gigabyte has released a new bios for their boards: F11. Has anyone here tried using it?

I saw that too. I've not bothered, no fixes that I require and no Agesa update. More hassle than it's worth.

Well, I've literally just updated it. I'll see how it goes and post back for others if anything noteworthy comes up.

Be surprised if you notice anything but no harm in doing it.

It's a man upgrading bios as I need to input all my settings and fan profiles every time.

True, I've just noticed my memory settings are back to stock again. Anyway, I don't mind too much as I'm still learning about the platform.

I've found this video which might help some out there. I haven't made all the changes listed but I did notice a definite snappier, less laggy experience.

Zeeflyboy · 16 Dec 2019 at 19:19

Useful video cheers, I just got my x570 aorus master today and 3900x arriving tomorrow.

Andy D · 16 Dec 2019 at 21:02

Managed to get 3400Mhz, FCLK at 1700 using 3200MHz FlareX with these timings. This is with 1.4V, seems stable. Tried 1.38 and crashed
Not sure what the best benchmarking tool is, but VRMark gives ..

I'd really like to know how this compares with someone else with 3900x and 1080Ti. Then I can stop fiddling about

I've not touched CPU OC'ing at all yet

Got my 3900X installed - haven't been able to do it over the last few days as I've got a bad back and it was being a right barsteward.

Installing it didn't go off to the best of starts - booted into Windows 10 and it instantly blue screened of death. Decided to take that as a hint to start afresh with a new Windows install and it BSOD'd every time I tried to install Windows again.

I'm running a X470 Aorus Gaming 7 Wifi and eventually found that Windows doesn't seem to come with suitable drivers for the Intel Wifi adapter. As soon as I downloaded some and connected the wifi antenna (strange that you have to have it connected, even if not using wifi), the install went fine.

Hopefully that helps anyone else who gets this BUGCODE NDIS DRIVER BSOD. Seems quite common from a search of the interwebs.

Currently using a Noctua NH-U9S as can't fit a full height cooler in the Lian Li. Will get the water loop reconnected in due course and then looking forward to seeing how the 3900X clocks compared to my outgoing 2700X
