I'm looking at mid range gaming laptops and was interested in the AMD offerings even though they're limited to 2060's because of the supposedly better power consumption and thermal things. I guess that shouldn't really be much of a factor if this is going to be a thing for them. I mean the 4800H definitely performs, no qualms with Asus about that.

Does anyone have from-the-wall idle vs. load measurements of the 4800H chips? I've only seen from-the-chip figures from the 4900HS, which seems to go only 4w above its on-the-sticker TDP.

If my anecdotal aural evidence is not wrong, M.2 is super grumpy about being written to and gets a lot hotter than SATA SSDs did. Like, just downloading poo poo from Steam kicks my fans into high gear.

I'm looking for a guide on how to OC my ram. I used the "safe" settings from the ryzen memory calculator but the system didn't boot. I don't want to just dial in a bunch of numbers and hope it boots, I just want to go in step by step increments to make sure everything is stable. I have micron e-die which isn't as hot poo poo as b-die but it apparently oc's very well.

Flash doesn't mind being hot, it actually benefits from being a little warm. The controller, on the other hand, is like any other silicon, and does not. If you can put a mini heatsink with some thermal adhesive onto the controller, (and this will depend on a lot of factors, like whether or not your specific SSD manufacturer decided to put the controller on the top side or not, or if your M.2 mount is tall enough to fit a mini heatsink) you can curb that.

I just noticed something sort of odd with my computer. I've got a 3800x cooled by an NH-D15 with a 1080ti. Temps in HWiNFO64 are all normal and within expectations, CPU idles between 30-40c and temps usually max out around 72c. The strange thing is, when I'm playing a game or doing anything that uses the video card, the computer obviously exhausts hot air, as one would expect. The difference between idle and load is very noticeable. However, if I do any CPU-exclusive task, temps rise on the CPU like normal, but the exhaust is always cold. CPU performance is perfectly normal and within spec, no signs of overheating or thermal throttling. So is this normal behavior, or could I have mounted the heatsink to the cpu incorrectly? I just would expect the CPU to exhaust hot air under load, which it doesn't seem to do. The 1080ti creates obviously hot exhaust when in use.

Your 1080ti is probably producing four to five times heat as your CPU while gaming, so it makes sense that their is more hot air to exhaust than when you're just stressing your CPU which wont produce nearly as much by itself compared to the gaming CPU/GPU. So yea, it's normal.

Yeah, the TDP of the 1080ti is a shitton higher than the processor. You have to consider the flow rate of your case too. If your case can turn over air faster than the processor can heat, then the exhaust is going to remain cool. But that same rate may not be able to turn over the air faster than the 1080ti can heat it, so the ambient air temp in the case is going to rise.

Your 1080 Ti under load is consuming 2-3x the energy of your 3800x, so combined tasks like gaming will be consuming ~2.5-4x more energy than cpu-only tasks. That’ll show up as exhaust heat. If you have top exhaust vents it might also be possible that cpu waste heat might be escaping that way! E: efb

That makes sense. I was just wondering when I saw temps of 72 on both the CPU and GPU, but could only feel temps coming from the 1080ti. I've got a meshify-C with 2x Nocuta 140s in the front, 1x 120 and 140 on the NH-d15s, and 1x 120 exhaust. Maybe that pushes so much air through the case that it never gets a chance to be warm.

I'm assuming you have a multi fan model 1080 Ti which will exhaust the hot air into your case which then has to be removed by your rear fan.

Edit: Just to be clear. When the 1080ti is at 72 degrees, I can feel it. When the CPU alone is at 72 degrees, it's chilly. GPU Idle in the second case.

When your cpu is 72 degrees it's drawing maybe 100W, tops, but that energy concentrated in a small area so the temperature is relatively high. When your GPU is 72 degrees it's drawing 200-300W that's spread out over a larger die so the temperature is relatively lower. That all gets transferred into roughly equivalent air columns, so the exhaust from gpu activity will be hotter than the exhaust from cpu activity (plus when the gpu is going strong, the cpu is probably taxed as well).

Wonder forgot to mention that, which is probably why Threadripper and EPYC are so brutally far ahead even at similar core counts and clockspeeds, like the 3950X itself competing with the 10980XE.Wonder if Zen3 has smoe smarter way of handling it's cache that can effectively reduce latency, because if so it'll just crush Comet Lake in Intel's last stronghold, clockspeed deficit or not. Wonder if Zen4 is going to significant gains merely moving to a a faster IF and DDR5 on top of any improvements to the core, or if that dependency is reduced in Zen3 with unified L3.

The trade off with the MCM model was worse RAM latency, but cheaper manufacturing costs and less NUMA fuckery. Anything you can do to mitigate that trade off, like faster RAM or IF cycles, is gonna help. But it is basically the only thing holding AMD back from clean-sweeping intel and it seems like clockspeed alone doesn't bruteforce past that bottleneck, so anything they can do in future designs to combat that is gonna be real important. Especially as intel starts moving again with new core designs starting with Rocket Lake.

Hey there guys I just got this card: https://www.amazon.com/GIGABYTE-Graphics-Windforce-GV-N207SGAMING-OC-8GD/dp/B07WN6WB4G A friend of mine recommended me to get this: CPU: https://www.amazon.com/AMD-Ryzen-Processor-Wraith-Cooler/dp/B07B428M7F (2700x) With this mobo: https://www.amazon.com/ROG-Strix-B450-F-Gaming-Motherboard/dp/B07FKTZC4M Are these fine?

Don't get a 2700X. 3000 is going to get discounted quite a bit once 4000 is announced, buy 3000 then.

I have a similar setup, Meshify-C with Noctua 140s in front, a 120mm on a Scythe Mugen cooler, and a 120mm exhaust, cooling a 2600X and 1070. I just (as in yesterday) realized that I had the CPU cooler fan on backwards for the past year  The CPU has been happily crunching away in the mid-70s even with the CPU fan literally fighting the two intake fans.So yeah, a lot of air helps too

Reason I had my friend go with the Pro-VDH MAX is because his case only supports microATX boards. [edit] Also I learned from the PC building thread that any "MAX" branded motherboard from MSI supports Ryzen 3000 series CPUs out the box, no BIOS updated required. That was another thing that helped making picking a motherboard easier for my friend, since he doesn't want to gently caress with any BIOS updates when building lol. teagone fucked around with this message at 03:29 on May 6, 2020 |

GRINDCORE MEGGIDO posted:Any news on x670? The only reputable rumor I remember hearing was from Digitimes and was that Asmedia got the contract again (like every other Ryzen chipset that wasnt X570, including B550), and it was coming end of year. The pure speculation I've heard lately is that AMD may just rebrand X570 instead, or not release a new X series chipset at all as Zen3 is the end of the road for AM4. If there was a wave of new motherboards pending imminently, the board partners would have leaked that poo poo to high heaven like they always do, so there might be some wisdom in that speculation.

What kind of features could they potentially add to a successor to x570? We already know that DDR5 is off the table for AM4. What would they do to incentivize people to upgrade? I'm on B450 and I don't see much of a reason to upgrade. I don't foresee pcie 4.0 becoming mandatory for the next gen of GPUs, and I imagine AM5 will be out by the time it does. I suppose if Zen 3 is another big jump in performance, it might be a smart idea to get the longest lasting MB for the long-term. Then again, Zen 4 on AM5 might be even better, so who knows.

Has there ever been a new CPU release without a new set of motherboards/chipsets? I can't think of one at all, even if they've been functionally similar. Going to go with an EPYC Milan release in September, and early 2021 Zen 4000 release in like, March. That means we should see leaks of X670 in I think October or so? Usually 6 months lead time on that.
