cheers appreciate that, really hoping i get that email 2moro or friday otherwise its gonna look more and more like a december delivery for me
Hey guys can I get a bit of advice please?
I've got my 9800X3D on its way so I'm picking a motherboard to go with it. I'm not too fussed about m.2 slots (3 is fine, 4 would just be a nice bonus) or tons of USB slots etc. PCIe 5.0 is also not a deal breaker, it'd be nice to have but I'd be perfectly happy without it too.
The thing that's holding me back from picking one is being unsure what I really need to do a decent overclock with the 9800X3D. I don't want to go too cheap and then find it's bad for overclocking. I'm happy to spend around £200-£230 but if that's no good I could maybe stretch further, any suggestions?
Also what's the verdict on RAM with the 9800X3D, is 6000 still the sweet spot or does it actually benefit from higher now?
Thanks
Truthfully, it won’t make a world of difference. Anything with good VRM’s will be fine. You’re not really held back much by the board unless you’re doing extreme overlocking where VRM’s and topology come more into play. No need to go overboard so to speak lol.
ASRock boards get good reviews. So the suggestion by the previous poster is probably solid. That being said, I have an ASUS B650E-F (my first ASUS board) and it’s very solid.

In regards to RAM. 6000CL30 is always touted as the sweetspot, and that’s largely true. Every chip will run it, and you’re virtually getting full performance.
However, 6400 is actually the optimum speed. Around CL30. It is shown to be measurably superior to 6000CL28/30, and often benches/performs ahead of a 8000mhz setup due to it being 1:1. 8000mhz will outperform it in productivity and some memory intensive benches due to higher bandwidth, but in gaming, 6400 with a good CL almost always wins. 6600 1:1 isn’t unheard of (LTMatt here on the forum managed it) but you’re really looking at absolute golden sample for that.
I’d recommend a 6400CL32 kit, and you should almost definitely be able to overclock it to 6400CL30 or even CL28 if you’re lucky. But there’s nothing stopping you going for a 7600 or 8000mhz kit and downclocking it to 6400 either.
Either way, shoot for 6400 if possible, and 1:1 (3200MCLK/3200UCLK, preferably at 2200 FCLK). If you can’t achieve it and can do 6200/6000, you haven’t really lost anything.
My RAM will actually push down as far as 6000CL26 or even CL24 with some extreme tinkering, but I’m not sure if it beats out 6400CL30/28 due to bandwidth. In latency terms it does, but that’s not the only factor. I need to bench both to know.

Out with the old, in with the new:
Decided to install my first ever AIO (liquid freezer 3 280mm) and so glad I did. Never realised how quiet they can be and the temps are awesome.
Took about 2 hours trying to get it to fit in my case, but totally worth it

My timing seems to suck. I was originally looking at a partial upgrade for my AM4 board, but getting hold of a 5800x3d is just not possible anymore, so my man maths decided to just go for the jump to AM5 (I figure I'll be on this CPU for a good 5-6 years like my current 2700x), seen this had just released and thought, "oh, good timing" not realising there is practically no stock anywhere.
Sorry if it's already been mentioned, but is it early 2025 when there will be more stock? May have to settle with a new GPU for now and wait for a month or 2.
Can’t mention the specific site obviously, but there’s been frequent stock drops on an extremely popular site over the last two days. Multiple drops, and not selling out straight away either.
Judging by this, the stock situation is easing. And tbh, the only reason there’s a real stock problem is because of the customs issues which created a huge backlog.
There will 100% be ‘gettable’ stock by the end of November, and it should be very easy to get at the beginning of December. I can’t speak for OC personally as I obviously don’t work for them, but despite them saying it’s sold out until 2025, I very much doubt it will be. They’ll be sent/received in copious amounts before long.

Only Noctua’s beat a decent AIO, and let’s face it, a AIO is SO much better looking than air.
Legend, thank you for the advice! Is there a good resource you can recommend where I can learn how to approach overclocking to 6400CL30? I haven't actually overclocked since the 2500k days, lol.
caved in, whats the motherboard to go for - £150 - 400, or is the tomahawk x670e with the latest bios good enough
will be upgrading from a 7800x3d, had 2 of these :O longest i've kept cpus tbh as they've been great and untouchable

has been solid touch wood, did a neg 30 on the PB curve and expo 6000 for the mem andf it's been rock solid ever since with the 7800x3d, nice one

i would also say stick with what you have, i also nearly caved in and got an x870e board but i currently have the asrock taichi carrera board and when i compared it against the newer boards mine was better in a lot of the points and only really fell short in the ram speeds for overclocking, but currently supports 6600mt/s anyways which is around the sweet spot for 9800x3d so i will hold onto this board for another year or 2 yet

Does anyone know of anywhere getting any stock? I thought I'd pre-ordered one from ****** but they just twisted it now saying they don't have any stock and don't know when its coming (when i pre-ordered it had a date etc).... I check OC all the time even though I realise unlikely to get a chip. Spent thousands ready for 6th Dec POE2 really wanted to play it on something other than my 2060 lol.... I'll regret if I cave and don't go for the 9800x3d now... Anyone got any leads at all?

Just get a 7800x3d in the meantime. If you go used, you'll minimise the cost when it comes time to sell.

I mean if its going to incur more cost ultimately the scalpers on ebay start to seem like a option. I'm looking there and waiting to see if the price dips once everyone gets their delivery from the first stocks. I also don't want to be re-opening the pc up and cleaning thermal paste and selling a chip etc I'll just wait one will show eventually, right? RIGHT!? XD
@Nitefly How are you getting on with your OC?@Cenuij after playing around a bit more this is where I've ended up.
I'm running a '-25' all core curve optimiser, with a +200 offset. It wouldn't stay stable with a greater offset... '-30' lasted 35 mins with the AIDA64 stress test before dying.
'-25' has just hit 3 hours 50 mins and going strong.
RAM timing and voltages as follows:
RAM latency at 69-70 n/s.
I'm not really sure how I could improve it from there. All pointers welcome
Edit: I spoke too soon… had a crashrolling back the FCLK. Not sure whether it’s the low CL that’s stuffing me!
So I think someone mentioned, you can lower your tRFC. 390@6000 or 403@6200 should be good for 120-130ns A-die.
I've discovered for my M-Die 496 is more stable. I'm basing this on tRFC 480 passed 8 hours of Karhu, but after 45 mins of TM5 I started seeing errors, but tRFC 496 (160ns) passes both.
I've also decided to give up on CL28, my kit is 2x32G and needs 1.52v to be nearly stable at that timing, but with max tREFI the sticks are very close to DDR5 temperatures (58-61c) where the heat might cause instability.
Here's where I'm at with RAM tuning, I think I'll maybe try one last tweak on the turn around timings and then figure out the minimum stable voltages after that. When I'm hopefully done with the RAM tune soon, I'll go back to the CPU and see what undervolt is stable with this RAM OC:

I am booting at 6600CL32 1:1 2200FCLK, so think my chip is pretty good. That’s with GDM on though, and it’s proving extremely difficult to try and stabilise.
Funnily enough, I’m even having issues getting 6400CL30 stable without GDM, even if I pump through quite a lot of voltage. I have stress tested the FCLK at 2200Expo and it’s stable.
Keep going for 6400CL30/28 GDM on, or go lower with hopefully GDM off?

6000CL30 RAM should work fine without any OC with this chip right? It seemed to be the consensous on the youtube channels 6000CL30 was some sweet spot and best to just go for that, is that your guys findings that 6000 works fine but over is finicky?

the general consensus is that 6000 should work without any effort at all (i/e out of teh box) im my case 6400 worked out of the box without issue in 1:1, but that doesnt mean they all will. a lot of it will come down to motherboard and chip
