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

Can you buy Teamgroup DDR5 RAM from UK retailers?

Doesn't seem to have wide availability yet.

There's some cheap 5600 MT/s modules I've seen in other countries, they seem to be selling it for less.

I have the Asus x670e Hero and 7950x

I have DDR5 G Skill 6000 C36 2x16gb ram but struggling to be stable at 6000mhz

Mobo only gives 1 D.O.C.P profile and i can only be stable at 4800 which the motherboard choose itself

Haven't tinkered anymore yet but i shouldn't have to increase ram voltage as its already 1.35 and is speced to run at that speed i also set the fclk at 2000 which is meant to be the correct 1:1 ratio

not sure whether its just bios that needs updating possibly as its so new

Try setting the infinity fabric clock to 'auto'. That's the recommended setting. I don't think flck = 2000mhz is guaranteed to work.

If no dice, then I would try bumping up the dram voltage to 1.4v (no point increasing more than that)

Have you tried bumping up the CAS latency to 40? Might help.

EDIT - Can you set an XMP profile in the BIOS? Most modules support XMP, and AM5 boards are supposed to also.

D.O.C.P= is Asus's profiling tech, and is different to XMP.

No XMP profile or expo profile in the bios just docp, only way to auto load the rams certified spec
Not on ASUS QVL either but then not many 6000 kits are, it most certainly supports it and higher though
Also i managed to run stable -25 curve 85 degree throttle and 180watt limit on cpu
Perhaps this could be whats gimping ram from running the full 6000
i'll default cpu back and try ram full speed

If you check OcUK website you will see they have several TeamGroup DDR4 and DDR5 kits listed and in stock.

If there is a kit you’d like to see post a link to the TeamGroup website of the kit you want.

I think that's a very odd reply @Gibbo. Shurely both you and 8pack would have been well up on this certainly weeks ago ? So why are you asking forum members for advice ?
 
It’s finally built and I’m ready to setup windows!

Had one issue in that the Ekb elite seems too big that it slightly pushed on the memory in the first slot and just gives me a c5 error :( which is a shame so going to have to order 64GB of ram or just leave it at 32gb.

Hi Gibbo,

Not sure what the webpage for these modules is, but here is the model number:

FLBD532G5600HC36BDC01​


Spec is DDR5 2x16GB 5600 MT/s

Zen4 runs hot as the sun, due to a very silly design. Making AM4 coolers compatible means the IHS is >2mm thicker than it needs to be. Going direct die yields a 21C improvement.

That's old news and due to performance scaling and stock voltage profiles, doesn't matter for an average user as it's quite easy to get temps down, performance up without changing cooling or trying to do direct die. Unlike the 8700k where it was very much recommended to delid, delid and direct die for Zen4 won't be necessary for anyone to do

It works for me, my Deepcool AK620 was only £48.

Basically, if people are bothered about the temps they should be able to use PBO2 to reduce the Vcore.

Personally, I would like AMD to implement some sort of auto PBO in the BIOS, that can set this up automagically for new users. I think because the temps have been so high on the 12700K and 12900K even at stock, doesn't seem motivated to ensure the temps are low at stock.

what high temps for 12700k?? my 12700k is great for temps,idle 26-30,while in gaming i never seen more then 59c,i remember on zen 3 for 5900x i was on idle 40-50 and load always 70 sometimes 80,both scenarios stock
