7800X3D now or wait?

[Noxia]

I'm going to try some new RAM, not because I'll get any benefit running at 6000 rather than whatever it is now but because I want to see if my MOBO (X670E-E) will actually allow me to boot using EXPO with a QVL RAM.

Edit: Wrong thread but kinda fits.

Other that’s expo. And a curve offset there is nothing really you can do. If you try to overclock it locks the speed to base clock

 

[Noxia]

True, just want to rule out if it was the RAM or not.

I mean look at this, ANY kind of tweak and it ***** the bed.

 

[Wing-Man]

Yer you should be able to run expo and tune ram

 

[Noxia]

Yeah exactly, I get it's not on the QVL list but still. Just one of those mysteries that has been bugging me since I built my PC (which is completely stable as is).

lift in performance for gaming

what exactly are you hoping for? more fps?

Yes, and higher minimums, and a smoother experience generally. The latter is more subjective than measurable, a bit like VRR which I can't do without.

I just ordered a Samsung UW so I think the 7800x3d jump will be sooner than I planned

I did want to wait till the 8xxx chips

I'm quite close to making a decision with this. I could sell my 5900x and pick up a new 5800x3d for around £100 outlay.

Or, I could do the upgrade to AM5 but I'd like longevity to upgrade the CPU as we progress through the refresh cycles. How does this shopping list look? There seems to be loads of choice for DDR5 but I'm not sure which set the 7800x3d would be best compatible with?

My basket at OcUK:

• 1 x Corsair Vengeance 32GB (2X16GB) DDR5 PC5-48000C30 6000MHz Dual Channel (SKU: MEM-CRS-01125) = £124.99
• 1 x MSI MPG B650 Carbon WIFI (Socket AM5) DDR5 ATX Motherboard (SKU: MB-372-MS) = £269.99
• 1 x AMD Ryzen 7 7800X3D Eight Core 5.00GHz (Socket AM5) Processor - Retail (SKU: CP-3DT-AM) = £374.99

Total: £777.96 (includes delivery: £7.99)​

£259.98 for the

Asus Prime X670E
comes with pcie5.0 and cheaper​

I bit the bullet as well. If the 8800x3d will be a big upgrade, I will just upgrade.

I have enabled EXPO on the Gskill set after loading defaults in BIOS as suggested by @Wing-Man and now the GPU utilisation is as it should be.

Here's some comparisons...

Spoiler: 5900x with 7900XT & 3200Mhz DDR4

Spoiler: 7900X3D with 7900XT & 6000Mhz DDR5

4k - slight loss in performance, no doubt due to the multi threaded aspect.

1440 - 2% increase

1080 - 10% increase

Typo in your spoiler for the 7800X3D, you put 7900X3D.

Well spotted, I'll get that edited.

@Dirk Diggler just to double check that, so you're saying it was only a 2% from a 5900x to 7800x3d?

Bit rubbish if so and will likely stick with my 5900x...

At 4k a modem cpu as little to no problem. So upgrading doesn’t really matter much difference

I'm at 1440p with a 7900xtx and 5900x

Really want to pull the trigger but can't justify it with those gains

The gain in 1440p should be more. Also, sometimes its hard to consistently quantify 1% lows which definitely improve with 7800x3d

 

[Wing-Man]

At 1080 the gains I had was massive but not to the advantage fps. The stutter and lag is gone.
