AMD Zen 5 rumours

So it's similar to FSB from 3000 years ago?

It's the infinity fabric clock speed, the link between uclk, mclk etc and I've never had a chip that couldn't do 2200FCLK.
On earlier Ryzen CPUs it would be set to half your ram speed, so 3000MT/s ram and you would set the FCLK to 1500mhz, AM5 changed this, the ratio is now best set 3:3:2, (UCLK, MCLK, FCLK they are all linked together) so uclk at 3000mhz mclk at 3000mhz (this is the memory clock which = 6000MT/s) and fclk at 2000mhz etc etc, but AMD state run FCLK at the highest speed you can.
BCLK which is basically the base clock is the FSB (front side base clock) from 3000 years ago of sorts.

No... tho as @Jamin280672 said BLK is still a thing.
AMD's CPU are MCM, or chiplet design, look at these two images and read what i said again.

how important is it to pick memory that is on the QVL list please ? just I'm looking at say the MSI Tomahawk motherboard at the moment, but struggling to find any of the memory kits I've been looking at on the list !
48gb / 64gb kits this is
Is there really a chance of >2 minute boot times if you use non QVL memory and it has to train each time ? I'm still on DDR3 (Samsung Green as recommended on here years ago - still going strong heavily overclocked !)
I was looking for 48gb or 64gb CL30, but also am considering CL36 if substantially cheaper
was looking at this but couldn't find on list:

neither seem to be listed unless I'm looking up wrong

I was looking at buying the same corsair ram for the ASUS x870-i itx motherboard and had the same worry as it weren't on the QVL list.
Now I'm fairly sure that it should be fine but then I read about another person using the same stick (on another board) and having instability issues that were solved when using another stick. Its was probably a bad stick of ram, but I really miss just plopping in ram and it working without issues or any memory training.

after 2 evenings of looking at RAM compatibility, boot times etc for DDR5 I'm half leaning back towards AM4 lol
just specced up a 5700x3D, Strix equivalent mobo, 64gb DDR4000-C19 RAM and its coming in 170 less than the AM5 platform with a 7700x
the PC I built for my son is around a 5800x3D and it's coping fine with 4x16gb sticks, something that DDR5 seems to have an issue with so if I am to go AM5 route I have to make decision now 48gb vs 64 vs 32 rather than upgrade later
RAM is almost double the price too - £200 for 64gb of 6000C30 RAM (or £190 if C36) - vs £115 for 64gb DDR4 4000 C19

It isn't, until it doesn't work
The main thing is that it does suggest the memory chips being used on those sticks are compatible with the BIOS, so if there's a particular stick (or set of sticks) that are absent it can be a bad sign and I'd consider that especially true for 24/48GB kits, since they weren't widely available when AM5 launched.
There's a chance if the memory is on the QVL or not. There are settings you can change to help, but not everyone has success with using them.
Have you checked the possibility of running that RAM near that speed? Seems excessively fast to me, especially for an X3D.
The 7700 / 7700X have widely differing prices depending on if you see a deal or are willing to import, so what price are you using?
You can get decently usable RAM down to £150 and I suspect we'll see some good RAM deals on black friday, though I suppose that'll apply the same to DDR4 too.
If you go for 5200-5600 DDR5 its much cheaper(~£150 for 64GB) than 6000 C30 kits(~£200) and the difference is not that noticeable unless you go looking for it with benchmarks.

Ive never had any issues using G.Skill kits on any board to be fair, wish I could say the same about other brands.
Ive just watched a video on that new X870-i, completely missed until I saw the video that its not X870E, its a rebranded B650e-i for twice the price, im glad I saw the vid, nearly ordered one myself.
AMD know how to confuse things.
X870E = X670E
X870 = B650E

Does it even matter for an ITX board? They're so small that they can't use the lanes of X670E/X870E anyway, so I'd imagine the only meaningful spec difference with the newer boards is USB4.
Soldato
Why pay £400+ for a board that you can basically get previous gen for half the price ? im sure a wifi 7 chip over 6e and a USB4 chip that steals 4 lanes from the CPU doesnt cost £200 more.
I’d be tempted to decide soon. If you need a lot of memory bandwidth then DDR5 is what you’re paying for and very much worth it IMO. If it’s just outright capacity then DDR4 is fine.
Yeah ASUS have definitely used the naming confusion to ramp up pricing.
My basket at OcUK:
- 1 x Asus ROG Strix B650E-F Gaming WIFI (Socket AM5) DDR5 ATX Motherboard (SKU: MB-6JX-AS) = £215.99
- 1 x Asus ROG STRIX X870-F GAMING WIFI (Socket AM5) DDR5 ATX Motherboard (SKU: MOT-ASU-03086) = £408.98
- 1 x Asus ROG Strix B650E-I Gaming WIFI (Socket AM5) DDR5 Mini ITX Motherboard (SKU: MB-6JZ-AS) = £239.99
- 1 x Asus ROG STRIX X870-I GAMING WIFI (Socket AM5) DDR5 Mini-ITX Motherboard (SKU: MOT-ASU-03091) = £408.98
Total: £1,281.94 (includes delivery: £7.99)

I knew it was a rebrand but because I don't upgrade that often I would prefer to have the x2 USB 4. Was considering the X670e-i but I heard some people where having issues with it and it also has 2 chipset to cool which aren't really needed (ITX build so trying to reduce heat if possible). Plus the price difference between the 2 isn't that great. So it was between the B650E-i and the x870-i. Head/wallet says go for the B650E but I probably will get the x870-i
Hopefully, or at the 7950x3d depending on price/performance
A bit daft when you already have a 7800X3D with leaks so far showing avg +5% on the 9800X3D at 1080p with a 4090
Well, depending on the power rating it’s going to be around 20% faster isn’t it.
unless you need USB 4 you would be crazy not to pickup 650 board, almost double the price for almost nothing extra!
