The new Raspberry Pi 4 is here!!
-
@retropi19
i have it for the 3b+ (double fan)
no noise and really good. -
@quicksilver this is a good idea, I'll get on and try this out tonight then get back to you.
(Off topic but, I actually have to go to work today to teach children python on raspberry pi!)
-
@retropi19 that's listed as a raspberry pi 4 case but the fact it has the heatsink part on the bottom side with the square on the middle means it's for older pi's that had the ram underneath.
It might be compatible but I wouldn't be able to confirm that.
The one I used was this: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F254219981743
I have one for my Raspberry Pi 3 which is relatively silent,
But this one which I have for my Raspberry Pi 4 is much louder. If silence is the name of the game you're definitely better off getting a small 5v noctua fan for around £10 and finding a way to attach that to a heat sink or a case. -
i dont have a raspberry pi 3b+
which one you have for the Rpi4? -
@retropi19 the one that I linked is the one that I have for the Raspberry Pi 4
-
@quicksilver I have tested this now and you're correct, anything above 1750Mhz and the raspberry pi 4 will underclock itself to exactly 1Ghz.
Interestingly, it also underclocks the minimum clock speed to about 300Mhz, down from 600Mhz
-
@Bearwynn I think I read somewhere that there will be a firmware update to change that limit. Perhaps you could try updating to see if it's already available?
-
Spent an hour or so tonight and now have RetroArch (with the XMB interface) running on my Pi 4 on Raspbian Buster Lite (i.e. I'm not running it from the Raspbian desktop). I also built snes9x2010 as a test (this required modifying the makefile slightly) and ran SMW2: Yoshi's Island as a test. The spinning island scene runs at 148 FPS. No time to test anything else yet.
Ohh, I noticed one issue: There is major tearing and some stuttering in both the XMB GUI and during gameplay. Something's not working as it should when it comes to updating the display. Maybe a GPU driver issue?
-
@quicksilver I'll keep my eyes and ears peeled. I can't see anything on the official forums about it though.
-
Is the Pi 4 4GB even out yet?
I can't seem to find it in stock anywhereAlso, do you recommend their power supply, or would any USB-C Work.
I see Canakit has a set that comes with an adapter, which is why I asked.(Same question for the 3B, is the Official power supply any better than the other brands?)

I can't seem to find it in stock anywhereYes, it was sold out first since probably the fraction of 4G produced was smaller than 2GB + 1GGB combined.
Also, do you recommend their power supply, or would any USB-C Work.
I see Canakit has a set that comes with an adapter, which is why I asked.Can't say, but I've seen some tests on their forums with various power adapters with various degrees of success.
(Same question for the 3B, is the Official power supply any better than the other brands?)
It is better.

try updating the firmware? i have see a couple of similar sounding issues in the firmware repo over the last weeks
-
@dankcushions I thought I had done that on this image, but I'll double check. Thanks.
-
I see that there is new firmware in test that helps lower the temps without performance suffering. It will be nice when that gets released.

Updated the firmware yesterday and it indeed seems to have solved that issue. However, setting video_max_swapchain_images=2 in order to reduce input lag makes the issue return. The performance also plummets (150 FPS -> 57 FPS in Yoshi's Island). This setting is performance intensive, but shouldn't cause such a severe degradation. Something's probably still not right with the GPU driver.
-
Here are some emulators being tested on the pi4
Saturn doesn't look good at the moment.
-
@Barcrest yabause-sanshiro libretro core clearly not running on the hardware properly. why even test on that when standalone exists? i do wish eta-prime would chill out on his quest for views and just wait until anyone who knows what they're doing has done the work for him. retroarch was reporting ARMv7, for a start...
-
@Brunnis they revert the firmware update probably they found the performance drop
-
@dankcushions he did an overclocking video and it was so bad and obviously for views.
He did over_voltage=2 and then two lines later did over_voltage=4, thus overwriting the first one.
-
@Bearwynn and in the videos I saw (dont know about his latest) he says nothing about proper stability testing. A lot of people out there just copy paste what they see him do and then wonder why their pi is freezing/crashing all the time.
