So close to upgrading now, fingers on trigger for base package

[LtMatt]

Yeah. Some theory about a bridge between cores causing latency?

If you do setup right, the workload is pinned to one CCD so there is no latency issue.

The second CCD only becomes active if CPU utilisation is high enough, otherwise it sleeps.

If the utilisation is high enough to wake up the second CCD, that helps performance and the performance difference between the 7950X3D / 7800X3D widens further.

Thank you for the information! I've learned something useful. Cheers.

So my state of play so far is ...

7950X3D ... Purchased from OCUK

Asus Crosshair X670E Hero ... Purchased from OCUK

Arctic Liquid Freezer II High Performance CPU Water Cooler - 420mm ... Purchased from OCUK

Ram is still to be determined ... DDR5 I know, but speed ETC, please I need a minimum of 64GB DCS especially can bust the 32 GB standards easily.

The 4090 is going to have to wait a little longer, I have a 3090 and its fine, this is my upgrade path just now.

Please help with my ram speed choice now please

I would have thought a 4090 being the priority upgrade especially with features like frame gen which will double fps in games like MSFS, for the cpu I’d just toss in a 5800X3D for the time being which would likely cost nothing after selling the 5950X and then revisit the cpu in a few months once the new AMD / intel stuff is out and you have saved up more.

I hear what you say Joxeon but my logic is thus, My RTX 3090 is still killer and the 5090 will come out next year, sometimes its best to skip gaps to appreciate performance differences.

This is the right time to upgrade for me, money was in my pocket and its a done deal now ... will grab a 5090 RTX year f
or the icing on the cake.

Thanks

i would go for whatever has the best single core ipc improvements the latest generation of chips as sims well if like x4 foundations crave a main single thread for the bulk of work and mc stuff to assist it.

These are the kits you want. Both 64GB dual rank kits.

Decent chance of them being Hynix A die too which is ideal for tuning.

• F5-6000J3040G32GX2-TZ5RK
• F5-6400J3239G32GX2-TZ5RK

Could be 2025 before you see a 5090, just as an FYI.

The trouble is that you will likely need to upgrade the cpu again anyway if the 5090 is anywhere near as big a jump as the 4090 and then the ram speeds of 6000mhz will be dated (intel is already up to 7500mhz etc) while the current AM5 boards may not be able to run the faster ram.

CORSAIR VENGEANCE RGB DDR5 RAM 64GB (2x32GB) 6600MHz CL32 Intel XMP iCUE Compatible Computer Memory - Black (CMH64GX5M2B6600C32) ???​

Get a 96GB (2*48GB) 6400 kit and run it at 6000, then if memory support improves you can bump it to 6400.

CORSAIR VENGEANCE DDR5 RAM 96GB DDR5 6400: CMK96GX5M2B6400C32​

G.Skill Trident Z5 RGB Series 96GB DDR5 6400:F5-6400J3239F48GX2-TZ5RK​

The Corsair is ~£100 cheaper.

They also do 96GB 6800 kits like: TEAMGROUP T-Create DDR5 96GB Kit 6800MHz CL36 - CTCED596G6800HC36DDC01. If you upgrade to Zen 5, maybe it will support 6800 RAM.

Edit:
Looks like the new Agesa released 1.0.0.7B is going to bump up the RAM support a big chunk: 7200-8000.

OK, will grab a 4090 before Christmas

Just as a side note, my bits arrived from Overclockers yesterday minus Harobro ... sulks ... But very pleased with the performance of the new parts in Flight simulators, the arctic II 420 is a great cooler ... only just fitted in my case with a slight modification, nice and cool and not so noisy ... awesome!!!

Thanks to all for the advice in this thread.

Next purchase a new ATX 3.0 PSU and then the 4090, in a couple of months, before Christmas for sure.
