Wasn't yours supposed to be delivered last week? Is someone walking it over or something

Mines here. Can’t do anything until Wednesday due to work going on in the house and electricity going on and off.

What's the case , placement of case fans ? GPU will also be dumping heat Into the case

Sure it’s the Lian Li 011. Fans I’m not sure about. Still seems on the high side doesn’t it?

**** poor timing that. Priorities etc.

I was going to pay somewhere to do it for me because of this but £180 no chance, I’ll wait

Oh yeah sod that. I've decided to wait for the 7800. Although LtMatt keeps unknowingly peer pressuring me to get the top one, I know deep down it doesn't make much sense for me, not that the 7800 does much over my 7700X at the res I am currently at either (1440UW)

The o11 is notoriously bad with a high end gpu and especially an aio on top of that. Had it, it was cooking my CPU badly.

Built mine up on the weekend:
7950X3D / Asus B650E-E / 32Gb Trident Z5 Neo RGB DDR5 6000 CL30 / EK CR360 LUX AIO

Previous system: 3900X (@LtMatt 's old one he sold me!) / Asus Prime Pro X470 / 32GB Trident Z DDR4 3200 CL14

Build comments - A bit of a pain, partly my fault, partly due to new Intel Lan, partly AMD:
- I flashed the bios from USB (the CPU worked immediately, so no issues having to use Bios flashback), but left the USB stick in and this caused issues when trying to install Windows 11, it failed at the 'copying files' section.. A bit of googling said to unplug all other drives, so I did (NVME / SATA etc) only to realise it wasn't those, it was the errant USB stick!
- Then on Win 11 first setup, it failed at 'lets connect to the internet'.. Even with the lastest MSDN ISO of Mar 2023 22H2 it does not have the Intel drivers.. So found an article on that, downloaded the driver, installed during setup and got passed that!
- Went to install the AMD chipset drivers, so went to AMD, they offer an 'auto detect' mechanism, did that, but it downloaded the v4 chipset drivers.. Queue a quick Win 11 reinstall and manually getting the latest!
- The EK CR360 Lux is quite nice as AIOs go, EK have polished what is normally a very generic item and the fact it simply uses a normal PWM fan drive for the pump and the fans/rgb are all standard connections means no faffing with proprietary software (although I am a Corsair fan boy and still have/use the Commander Pro (and lighting node pro) and once setup in 'hardware' mode, uninstall iCue to ensure it's not messing).

General issues:
- with just basic PBO enabled (no tweaking) and EXPO, when I left the PC off (at the wall) and powered it back on a few hours later it got stuck at memory training.. (thank god for Q-Code display on the motherboard!) I cleared the CMOS (thank god for a rear plate mounted button!) and got it back to the Bios, and just enabled EXPO again and it booted/rebooted fine, I'll see how it goes as I power off the PC at the wall when not in use, so not sure, I don't think PBO is the issue.. I don't intend over clocking, more undervolting if anything as I am more cool 'n' quiet these days!

Gaming:
Instantly had a 15% uplift @ 4K120 based on like for like (same settings, same GPU) in a number of games. The 3900X was limiting those slightly as GPU would not always be maxed out when getting 120+ fps, so no surprise

General:
Aside from the laboured boot process, windows is super snappy, the NVME drives and the motherboard seem very good to me, lots of features, easy to install and updating the Bios was a breeze, as well as I could hope for considering the CPU had only just launched.

Productivity/Benchmarks:
I immediately checked and found it on par with review samples and thats all I can say, it's bloody quick none the less, but I knew this before buying..

Positives:
- Out the box it flies.. AMD have really done a good job of maximising the performance you get out the box, despite all the X3D specific rules, I just installed the latest AMD chipset drivers, installed the Xbox game bar as mentioned previous in this thread and got a nice uplift in gaming, I am not chasing things, only checking it was parking cores when it should.
- The initial experience of a new processor with new LAN chipset and other 'new' things wasn't as bad as the old days.. I didn't even have to invoke Bios Flashback, the CPU just worked and allowed me in the Bios immediately.
- Despite being expensive, I think this mid range of B650E/X670E with plenty of PCIe bandwidth for GPU/NVME isn't too bad, they are expensive, but the bandwidth provision is quite future proof and AMD do (lets hope) make their chipset generations compatible to spread that over a good period of time.
- It runs cool, very cool indeed, the AIO is overkill and I could have used the AK620 air cooler I was temporarily using.


Cons:
- AMD's 'autodetect' method on their website needs fixing.. Anyone not following a guide may end up gimping their gaming performance.
- Dare I say it's a bit 'boring'? This last couple of generations of CPUs from AMD/Intel aren't like the old days where you get the top end CPU and then overclock it by 20% with a linear increase in benchmarks and general performance, but those days are long gone, although on the flip side, this is likely the first CPU I'll not bother overclocking other than RAM timings and maybe just enabling PBO, although if it increases heat/power appreciably I'll not even bother.


Overall, very much living up to expectation and I love these days of Intel/AMD fighting it out, it absolutely embodies the notion that the consumer wins in these situations.

I’m an idiot when it comes to new tech, so I honestly have no business telling anyone they should or shouldn’t buy this or that. I can however see others situations a little better from the outside and I would honestly say if you are going high end get the 7950 3d. Do you need it? No, your current CPU is just fine If you are gaming and doing other things I would recommend the 7950x 3d just incase games start making use of it more in the near future.

TBH I don't even need what I have now, I basically play old games (when I can be bothered) I have never had a high end CPU tbh, always gone I7 etc, last PC was on a much stricter budget and had a 3600x? or 2600, I get the numbers mixed up all the time tbh, whatever would have been fairly decent when 2060 was out (I had a mini itx build).
It's like with cars, I don't drive like a **** but it's nice knowing you could if you have a fast one.

CPU's are where reality kicks in, especially when I remember how long the Q6600 was relevant for! I am still on the line thinking do I sell my monitor and get an LGC2 because I do notice the difference in resolution switching between 1440UW and 4k. That said, the upscaling is decent if you have a card that can handle it so good compromise? I dunno, I always have these internal struggles (plus impulsivity from ADHD), bad combo.

I’ve got a 011xl and it’s never been an issue. I’ve got all fan slots populated with Noctua fans but it shouldn’t make that much difference. My CPU temps are very rarely in the 60’s (13900k) and my 4090 is always in the 50’s.

7800X3D at $449 looks 'bad' value to me, compared to the 7950X3D at $699. $150 more for double the cores is IMO a very good deal.

Speaking from experience, there are already several games that benefit from > 8 cores, especially if you're a normal person and have some background applications running. Over time, this will only get worse.

The 7950X3D being so much faster at productivity, applications etc means it's the obvious choice for someone prepared to spend the premium to get on the AM5 platform.

For the vast majority, 5800X3D, cheap AM4/DDR4, or a 13th gen intel with z690, ddr4, are far more sensible choices for gaming performance per dollar.

I don't think most realize that you need a 4090 to actually tell the difference between Zen3X3D and Zen4 X3D.

 

[LtMatt]

Anyone getting high temps in Warzone on the new 3d CPU? A friend has one and he told me he’s seeing it hit over 80 degrees. He’s using a 360 AIO, which is what I will be using, I wouldn’t be pleased. Is there something he could be doing wrong @LtMatt?

Is he using a Nvidia GPU by any chance? Because I noticed much higher than normal CPU temps with my 4090. However, when I put the AMD GPU in the chassis, the CPU temp drops 20-25c in Warzone 2. See my CPU temps here as an example.

I did some debug at my end and I noticed that a app called Nvidia container is using 5% + CPU cycles, and that appears to be causing the higher temperatures. It seems like a possible Nvidia driver bug to me.

The o11 is notoriously bad with a high end gpu and especially an aio on top of that. Had it, it was cooking my CPU badly.

I have an O11D Evo, I have 3x 140mm intake bottom, AIO in side with 3x 120mm as intake, 3x 140mm top exhaust. Temps fine with fans set to 650RPM (AIO 800), but what I would say is that since putting the GPU vertical, temps did increase a bit. Nothing major until I got the Gigabyte 4090 but that must've been faulty as the retailer deemed it so when I returned.

Good point Dave, didn't think of it like that. Problem is it's the same old thing that pushes you to spend more like "oh the 4090 is 'only' 300-400 more than this 4080 I was looking at and it's better".
I suppose the other thing is we hopefully have another 3D gen to go before they potentially move to AM6 so it is unlikely to be for a huge amount of time I'd have it.
Side note, I don't really understand the tech on CPU's any more, my brain can't comprehend how this 3d CPU can be faster than a 129000K running at an OC of 6GHZ.

PS: I am really crap at editing a post on mobile, I don't understand how to insert a new quote when editing.

Havent tested the xl but it should be better since it has an outtake fan at the back. The normal o11 doesn't have a fan there and it stinks cause of that

I read somewhere that if you have good intake, you want your exhaust running slower so it doesn't exhaust all the cold air out too quick but I get cooling has loads of misinformation around it. I'm not using the 120mm exhaust slot currently.

I admire people that have had the 1080ti experience for example and made it last because it’s stood the test of time.

CPU’s I’m usually not as quick to pull the trigger. From the 10900k to the 13900k is the most I’ve managed.

The thing with me is I tune everything, then run out of things to fiddle with and strangely start missing the process of testing etc. I honestly think I prefer that to actually playing games.

I had an Ultrawide monitor before I got my 4k and I loved the Ultrawide but the black bars started really ******* me off. Some games worked fine with some adjusting but some older ones especially were not so great. I used to get motion sickness with that monitor also. Doom was horrendous, I was ill.

It’s one of those hobby’s where if you want to have the best you are going to be upgrading constantly. Most of it is pointless, it makes little difference but I’m not harming anyone and it keeps me happy

Luckily I have only had one game that didn't support UW (Elden Ring) but yeah it sucks. Totally get about preferring fiddling with hardware than playing, I really enjoy the researching of parts etc prior to building. I am too far behind now for CPU tweaking, when it was just managing temp and base clock increase it was fine. I don't understand all the PBO stuff at all. All I did on my current is put it to -15 and I have no idea if that was even beneficial lol.
Memory? Forget it, nothing can convince me that is worth is on AM5.

Whoever said that is clueless, lol

I'm not gonna go back and find out lol. I was going to WC originally but got put off by the perceived difficulty, but as time goes on I realise I don't care about aesthetics so bendy tubing would be acceptable to get the build in my skill level.

Yes he’s using a 4090. I honestly assumed you were using one too in your testing. Can you disable that software? Have you noticed this in any other games using your 4090?

Sorry for all the questions. I’m just going to be using mine with a very similar setup to his and I can’t have temps in the 80’s. I’d have palpitations in the high 60’s. Are these 3d’s hot without opening them up and voiding warranty?
