I found on my laptop ( and some others) the GPU and CPU don't make good contact with the heatsink. This can be resolved by 0.5mm shims or 0.5mm washers. However check after you repaste and tighten, remove the heatsink again and have a peak at the heatsink. See if you have any clean spots. If...

I'm considering getting a vapour / heatpipe combo heatsink created which should help things a lot. Also missed opportunity for additional cooling in terms of surface area of the fin array. Need to familiarise myself with cad first though.

I don't think there's a 17 inch system with equivalent specs are the moment. Which is a shame as I'd of preferred 17 for my own build.

https://www.pcspecialist.co.uk/saved-configurations/nova-15/VH5t6j8RxP/ Took the liberty of building you something You could upgrade to a more powerful cpu for an additional 70 or a more powerful gpu for 80 Selected a 2 tb storage device however you may not need so much space so could reduce...

For £1500 you could get something very Powerful. If portability/ battery isn't a main concern check out the nova series, they have desktop AMD processors up to 12 cores and 24 threads.

I would have to run ccd0 at 2.8ghz all core vs ccd1 running at the stock 3.6 GHz for them to run at the same powerdraw under full load. For the time being I've set the windows CPU power limit to 99% this prevents boost behaviours so the CPU will only hit 3ghz both CCD. Of course ccd0 still runs...

I use a laptop cooling pad that also lifts the laptop a fair amount. My ccd1 temperatures are more than fine it's this powedraw discrepancies that causes the issue. I'd be 10c below thermal cut off otherwise which is toasty but acceptable given the transistor density of this CPU. Haven spoken...

Yes it reduced temperatures but not enough on my system. Combined loads still cause thermal shut down. My particular 3900 has a CCD that draws 20% more power than the other which is causing the issues for me. So during CPU only load one will max out at 80-81 whilst the other will 96-97 . ( So...

Be sure to find that section in their warranty and refer them too it :)

Direct them here https://www.pcspecialist.co.uk/forums/threads/bios-updates.58007/ Having recently done a bios update I can tell you that once pc specialist send you the bios and update tool from a warranty/legal perspective you become authorised personnel. As they have given you the tools and...

Just what came on the tech support section and the latest from AMD ( latest a week ago anyway) I utilised open hardware monitor as this seems to be the most accurate and comprehensive sensor software for our laptop. See photographs below of both CCDs set to 1.05v at 3.6ghx during a cinebench...

I've emailed AMD as I think I've discovered the source of all the issues . ( Could be bios related but I'll find out from AMD to be sure) CCD0 draws 15-20% more power for a given clock compared to ccd1. So for example to get them to draw the same amount of power at 1.05v I have to run ccd0 at...

That's the size of the copper shims I used :] GPU gets 77c under load playing metro exodus for 1 hour. CPU gets to 97c on hottest core 85c average temperature. Unfortunately that one hot core can still cause thermal cut off at times so I've taken to just running the CPU without boost behaviour...

That's odd voltage should still fluctuate when system is idling. I went the shim route massively reduced GPU temperatures and made CPU temperatures manageable with default 88w ppt etc ( by 20c when idle and 15 underload for GPU and by 10 or so for CPU) this is in combination with bios update...

I'll keep my fingers crossed anyways, the reported IPC and clock speed increases will presumably be at the same tdp so would be great at 65w I can foresee 3.9-4ghz all core boost in the same thermal envelope. However even 3.8ghz with an improved IPC would be a decent uplift. Every second...

B450 boards will support ryzen 4000 with a bios update. The issue is the ROM being to small to include every chip so likely will loose Ryzen 1000 series support in order to add ryzen 4000 support. AMD changed their minds after community pressure :)

Definitely more convenient these days. Used to be fun times using modified bios and potentially bricking the system heh. Also I suspect that there is very low odds of a bios update to add support for 4000 series processors. :( Not that it's likely I'll need more horsepower but the option would...

Exact same thing with desktop motherboards they generally create applications in order to automate the process or have a secondary bios that it's read only. The extra engineering is worth it in my opinion as long term it reduces amount of time customer service has to be involved. Bios version...

Not having much luck like dealing with customer service. My partner tried to be helpful and call whilst I was at work but they don't record what bios was shipped with the units. Protip: start doing this. They advised my partner to inform them what the first screen says so they can tell what...

There's no tone there. But these are not excessively high power parts from a electrical perspective. 65w tdp one should expect high temperatures in a laptop but the laptop shouldn't crash. Like I've said before I've had 95w part in a laptop form factor before now and it was toasty but well...
