Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

[shalke]

I'm close to pulling the trigger on the following unless anyone can suggest improvements:

7800X3D
NZXT Kraken X53 240mm AIO
Gigabyte B650M AORUS ELITE AX
Corsair Vengeance RGB 32 GB DDR5-6000 CL30
Western Digital Black SN850X 2TB NVME
Sapphire Nitro+ 7900 XTX
be quiet! Pure Power 12 M 850W PSU
ASUS Prime AP201 MicroATX Mini Tower Case

Total: £2464

I wanted to go for G. Skill Neo 6000 CL30 memory but it's out of stock everywhere in the UK (both the RGB and non-RGB versions).

Swapped from the Corsair RM850x to the be quiet! Pure Power 12 PSU as it's ATX 3.0 compliant / supports PCIE5. It's also slightly cheaper.

I did consider the tempered glass version of the AP201, but the PRIME wording down the side is really putting me off. I don't understand why they added it.

Will also go for some custom sleeve cables to top off the build (colour undecided).

Quite nice choices. I'd go with it.

I would get a 1000W PSU at the least, as even if you're OK with your current list of components, you can be future proof when the need arises.

Not really. The current config he is using around 500W at max load, where games do not have max load. I think future wise, because of electricity costs, vendors will focus on efficiency, unless you get a 4090.

Finally got my new 7950x3d rig built at the weekend, didnt have time to mess about with pbo or anything though, going to try that tonight

Is there a good base negative offset to start at for 7950x3d curve optimizer? Want to save a bit of testing time if i can.

Also, has anyone got a base point for a ppt limit? Only seen a couple vids mention this, but they were using different cpu's

I’ve been following your improved timings for various RAM. Based on what you have recommended for others I think I could tweak mine a bit. Currently it’s running EXPO II.

Run Aida64 and maxxmem and share your results with the stock profile / EXPO profile vs the settings below and see how latency and bandwidth improves.

To disable geardown mode in the BIOS > DRAM menu look for an option called CMD Mode and set to Buf.

Thanks for that. Really appreciated! I should get some time to do that this week.

@delta0 Hey bud, can I ask what memory you have?

Ok. Cool. Thanks for that. I've got the 32Gb Corsair Dominator Platinum DDR5 6000 CL30. I think they are Hynix.

I tried tuning my memory last week with the help from @LtMatt and followed his advice. This was on the 1408 bios, and I don't know what was causing it, but my system would come to a grinding halt in BF2042 and a hard reset was needed. So I reverted everything back to default because I had to methodically go through everything as I probably applied too many setting at once without doing small adjustment and testing system stability. Instead I just applied all of them (PBO, CO, Mem) at once and jumped it. These things take time apparently to get it just right. Patience is key.

On Friday last week ASUS released the 1409 bios. I'm using ASUS Tuf Gaming X670e Plus WIFI and I am pleased to say that the motherboard can actually support EXPO II now with the Corsair memory. It's the first time I've been able to enable EXPO II without it giving me a BSOD as I try to get into Windows so that's a result.

So currently I'm set to EXPO II default profile in the 1409 Bios. I was thinking about attempting to dial in the memory again this week but I'd be interested to hear how you get on.

Here is a screen grab of the benchmarks I just took with the apps LtMatt recommended.

Try the timings I suggested for Delta. They can be improved but its a decent starting point.

Here's what I score in those benches running 6200C28.

P.S - Don't try to copy these unless you are using A Die kit.

voltages are so low with a die? 1.1 is silly low.

you have any recommendations on voltages/timings for 6200 on the what i assume is m die with the corsair 6000c30 expo kits? I didnt actually check what chips were on them.

i'm running similar timings at 6000c28, 1.4v, my aida sits around 61-62ms.

i did try [email protected] on loser timings, forget other voltages but definitely not stable, booted into windows that was about all it could do so stopped and focused on 6000c28.

6000c28 seems rock solid though, did a couple of 5/6hrs sessions of cod with the lads weekend, no issues at all and still getting **** on haha.

Voltage used was 1.41v with VDDQ at 1.31v. My SOC voltage is accurate and 1.2v is actually quite low for 2167FCLK but my sample works at that voltage and lower is better assuming no issues.

If you post your M die timings I can give you some suggestions. You’ll probably need 1.47v -1.53v to be stable at a guess.

You mentioned FCLK and possibly adjusting that to 2100? Should that be done after applying and testing the above timings? Also adjust in small increments?

arh ok, yeh assumed it was some bug hah.

thanks mate, i'll post up tonight at somepoint.

i have the issue with my bios not have GDM option, not sure why MSI havent added that, was going to see if there was a beta bios on their forums, using latest from their site which says beta but couldnt find the option.

 

[LtMatt]

Leave that till then end once you have memory and curve optimiser sorted, then you can play around with it.

Most samples will do somewhere between 2067-2167Mhz. Higher is better but the biggest performance gains will come from the above rather than FCLK.

Stability test of Karhu with cache enabled running overnight is a good way to test FCLK (and memory) stability.

If FCLK is too high the system performance can drop (can verify using Aida64 latency/bandwidth or with Karhu hover your mouse over the % sign when testing stability) or the system may randomly restart. However, that can also be caused by too much curve optimiser on your best cores, so you need to take a methodical approach to tuning both.

Spoiler

I highly recommend Karhu for stability testing btw, its one of the best and well worth the small cost to buy to own. I use it more than TM5 these days.

Yeah it's not a huge deal but having it enabled adds a little bit of latency. People moan about longer boot times so you have memory context restore (MCR) enabled but that also means you need gear down mode (GDM) enabled on AMD which has a small latency cost.
That's why I keep MCR off and GDM off and put up with a ten second longer boot time and lower latency = better performance.

I do have MCR off, is it pointless without being able to turn off GDM?

Hello guys - this is my first post so sorry for my not too perfect english.
My spec: 7950X3D + Strix 670e-e + Vengeance 6000cl30 expo + RTX 4080 Palit.
I'm still testing and trying to max performance of my computer but I have too many problems with asus bios. Sometimes 1/2 beta bios per week and the latest one 1202 is really bad performer if we talk about performance.
For now I'm trying to UV and some memory OC. With my Corsair 32GB Vengeance cl30 now I'm testing 6200 with some lower timings.
Here are my zentimings:

Standard zentiming voltages were - VSOC 1,35V MEM / MEM VDD 1,4V / MEM VDDQ 1,4V and I set CPU VDDIO to 1,32V from 1,4+V (all expo settings).
With previous bios 1004/1101 - I had better scores everywhere even on 6000MHz memory.....
For now I tested all my testers (few 3DMarks and few Cinebenches), few games and few cpu/mem burners without problems.

My standard settings in every bios are: PBO Exhancement 80*C (scores boost here) and EXPO/EXPO tweaked (little better scores on older bioses).
Any more advices ?

 

[sym30l1c]

So, I finally rebuilt my system and installed my 7800X3D. When I launched the system the first time, my SP was 96, but it dropped down to 92 after updating to BIOS 1202 (ASUS Crosshair Hero). Anybody have seen this?

I'm surprised that under heavy load the CPU gets up to 80C even with custom waterloop.
Also, I've run Cinebench a few times. I pretty much get the same scores with our without EXPO I or II enabled but haven't got past 18000.
Need to do more testing!

 

[LtMatt]

mine below

Yeah keep MCR off and disable GDM if they ever add it in future BIOS. However as they don't allow you to disable GDM you may as well keep MCR on for now and have the slightly quick boot time I guess.

My suggested changes would be:

RRDL 8
FAW 32
WTRS 4
WTRL 16
RDRDSCL 7
WRWRSCL 21
RDRDDD 4
RDRDSD 2
WRWRDD 8
WRWRSD 2

SOC 1.25v - 1.3v
VDDP 1.100
MEM VPP 1.8v

Your resistances are a little odd. Are those settings you've set or are those BIOS auto options?

Other than that looks fine.

SOC 1.25v - 1.3v
VDDP 1.100

FCLK could use a bump once you have everything else stable. Aim for 2033-2167Mhz.

Note higher FCLK may require higher SOC voltage so at your own risk.

Everything else looks good.
