*** AMD "Zen 4" thread (inc AM5/APU discussion) ***

Yeah, iCue...used to have full corsair stuff and some fans just kept on randomly showing up or disappearing. Your ram are fine, icue is the issue.
Phew, that's good to know. It does seem a bit hit and miss, I formatted my old PC yesterday and installed iCue on it, no matter what I did/uninstalls etc it just wouldn't start on bootup so the fans would be their default colour. Formatted again and installed it and it worked fine.
 

Maybe a heads up for new owners overclocking.. Seems Mr rambles a lot fried his sample 7950x.. Awww :rolleyes: maybe AMD or MSI will send him another free new one. Maybe if he paid for it, he would have treated it with more care or not guessed with a new piece of kit that has just come out and no one really knows their limits. So step with care people with yours.

He rambles in the video that he doesn't think it was him but maybe a faulty CPU... take that with a grain of salt, while he was on twitch he just rammed it with settings that he was guessing. The Asus board he used that cooked it may also have a BIOS issue too or just the AMD BIOS so far needs updating more to make it more safe, but again he should know better.

He was running GeekBench at 5.5Ghz all core at 1.425v, i don't know about Zen 4 but those would be a lot of volts for Zen 3 which in a heavy load like that doesn't get much past 1.3v tops, it cashed during the bench and never booted again.

Don't have it anymore but remember there was a way for your RGB to work while having that crap uninstalled. Don't remember exactly how. If you have it open - at least with intel cpus, it prevents the CPU from boosting to single core max boosts and it increases ram latency by a couple of nanoseconds. I assume the same happens to amd cpus as well.

Best advice anyone will ever give you, get rid of any RGB from your computer. Parts work worse cause of them (for example RGB fans are just terrible - cause usually fan blades are shorter than normal fans to accommodate for the blinkblinks) and the software you need to run them is absolutely horrible.
 
If any of you get a Zen4 CPU and have Fallout 4 can you test it out please if you have some time:
 
If you are going to buy a 7950x, don't cheap out that much in a motherboard. For a 7900x and under I wouldn't be too bothered and yes you can always set PPT wherever you want. But I just wouldn't cheap out that far with a flagship CPU purchase in mind.
The minimum I'd be looking at is something like a Gigabyte B650 AORUS ELITE AX. Now if you want full PCE-e 5.0 on everything, you are ofc going to have to up the budget further to get it.
None of these prices are attractive as we all know, the world being in the state it's currently in. It just is what it is !!!
Prices cuts will appear at some point, (probably during Q1 next year) but as an early adopter you are going to pay for it.
The impression I get, is that improvements to MOSFET design /spec result in improved efficiency and power delivery. I know this is something all gigabyte and ASRock boards now have, but I'm unsure if the Asus and MSI boards have the same or similar design.

EDIT - The top end MSI boards seem to have 'Smart Power Stage', which is basically the same thing as DrMOS. Link:

Is it possible that DDR5 memory speed support is simply better on AM5 gigabyte boards? since they all mention speeds upto 6600 MT/s (for some modules).

All the board makers use a few different brands of components to build their motherboard VRM's with. Dr MOS is one such brand (there are others) and it isn't a case of "we build with Dr MOS we have the best VRM" There are quite few different ways to build up the VRM. If you want to learn more about VRM's you can't go wrong with Buildzoid's channel on Youtube. I really don't want to type an essay about VRM construction in an AM5 discussion thread. But I would like to think that I've given you a good source where you can learn more about VRM's for yourself :)

I'm sure you are correct, but I'm comparing to my crappy B560 motherboard with 5 MOSFETs for VCORE, and a more primitive power design. I'll check out some of his videos later.

Question for those who primarily game and got the 7700X over the 7600X, why? I have not seen a benchmark that separates them gaming wise. I also don't buy into this "consoles have 8c so you need that". Just want to make sure I haven't missed something obvious.

Have a look at HUBs 7700X review. They have it as the fastest gaming CPU atm. Valid question though, would hazard a guess at the two extra cores adding a little bit of potential future proofing and slightly better for productivity apps.

The price is certainly more attractive on the 7600X (for just games). Some may prefer to wait for the 7700 (non X) release.

I have watched it now and this is what I mean, on the average chart 7700x was 218, 7600x 211.

Can get a 7700x for £390 right now, 7600X is £314. When the 4K benches show 1-2fps difference it's hard to justify the extra £80 but as you say, a bit more futureproof.

Yeah I think regardless of choice, it will be good cpu for years.

It depends how long you'd like to keep the CPU for. I'm loathed to 'downgrade' to a 6 core, even if the total MT performance is better on the 7600X.

I'm tempted by this price tbh. Wonder if we will see prices fall to this amount soon?

Can already get 7900x at a decent discount, less than i paid for mine and I'm sending it back soon. Even though will cost me 10-11 to send back i could save another £20 just by ordering it again elsewhere, but i might just go Intel instead.
 
tbh, with antialiasing improving in games all the time, ill happily settle for 1080p resolution if needed. I can probably play games at 1080p for quite a few years, without upgrading my gfx card. Or, use DLSS or similar technologies, if that's an option.

I care more about steady performance in games. If I can also spend less time waiting for stuff to load or install in the future, that's a nice bonus.

This is an interesting point.
I game on a 3440x1440 34", however recently I've noticed MSI have a 30" 2560x1080 display, if someone made a higher quality 30" 2560x1080 display I'd probably go to it.
 
Regarding waiting for the Zen 4 vcache CPUs, the problem is that these will be slower than Zen 5 in most or all situations, and these are scheduled to come out in Q4 2024. And both of these are drop in upgrades...

Plus the likely high prices £500+ likely. But they will give AMD the performance crown, at least for games.
