I updated my Time Spy score and went backwards after upgrading CPU

[Anooshorseville]

Hello, I am sad and confused. And have spent the entire day going in circles.

When I first got my 5090 I made this thread https://forums.overclockers.co.uk/t...be-expected-from-a-5090-in-time-spy.19006540/ with my Ryzen 7700

My 7900X3d arrived today and I was excited, all I can say is, NO MATTER WHAT I DO, it will not boot with two ram sticks, I have latest BIOS, and absolutely any which way I put in a second memory stick, it will not post to BIOS.

Moving on to my Time Spy score (non extreme)





So after what went on in the other thread, the most confusing thing, with my ONE stick of ram in, is my GPU score went up NOTABLY, and my CPU score went DOWN LOL

MAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAN

TS HOF has only 20 48K/+ entries (in the world)therefore 48K is an extremely difficult score to reach.

So upgrading my CPU, but losing a stick of RAM, and a lower CPU score than with my 7700, yet well over 48K GPU score

I'm banging my head against all four walls

I REALLY would appreciate some input

With one DIMM, you have single channel memory. This will reduce CPU performance. You do, however, now have more cores.

Ignore the synthetic benchmarks for now. Your real issue is that you can't boot with two DIMMs. That needs sorting or you'll be stuck with single channel memory.

Secondly, the 7900X3D is a dual CCX CPU. There will be a noticeable delay when the second CCX is used for gaming loads. Ensure your OS and AMD driver setup is spot on to ensure it's running at its best.

It's a huge issue and I don't know what's left to try, it will NOT post with with two sticks of RAM, any which way I try

Did the old CPU boot with 2 sticks?

Maybe the new CPU is either making bad contact with the pins and needs re-seated, or you mangled a pin in the socket related to ram while doing the CPU swap?

Thank you, yes my old CPU everything was entirely normal, I switched to this 7800X3D and all hell broke loose, only one stick of RAM will allow me to even get into BIOS

Thanks you all, I flashed bios, reset bios, removed battery, everything.

Honestly I been at this all day, until I bought much Guiness and decided to drown my sorrows and play BFV with one RAM stick. And then I ran time spy out of sheer morbid curiosity

I don't know why my GPU score increased as I didn't change anything in that regard - other than the different CPU and ONE RAM stick.

I just ordered an ASUS ROG Strix B650E-F Gaming WiFi - if I still have the same problem I'll just send it back and try another approach - it was a rush choice, from desperation

If there's any other boards I should consider I am happy to cancel this one, depending on availability/price etc - from what I can gather it's at least an upgrade from my early revision Gigabyte B650 GAMING X AX? I payed near £200 for it when it was first out...

If you've crossed off the usual suspects, it's time to check the CPU socket and its pins. You have to input a lot more effort to swap the board than check the socket - it's an easy test.

Do you have a 7800X3D or 7900X3D? If the former, you can ignore my comment about two CCXes and drivers.

7800X3D

Thank you all very much

ONE of the many things I did yesterday was install my 7700 again and the same issue so I just think I busted my mobo, I will check the pins but right now, despite one stick of ram, all is working well in cinebench r23 and time spy and BFV and great performance in B06 so I'm just going to leave it all as it is, and when my ASUS boards arrives I will swap everything out and take a pic of the pins in my Gigabyte board and upload it here.

By MOST accounts, my Time Spy, and r23 multi core scores (~18200) all seem to be acceptable so my new board arrives in 2 days, I'll update then

During the 10 minute cinebench run my temps remained very stable at 81C that being said my cooler is a cheap Thermalright Peerless Assassin 120 SE - which is pretty solid for the price but I imagine people with 7800X3d chips probably use far more impressive cooling - it was originally purchased for my 7700

This is what I would do:
Reset CMOS, update to latest BIOS, leave everything at stock, don't enable XMP/EXPO yet, wait until you've managed to get it to boot with two sticks.
Make sure RAM is in recommended slots for your board.
Try each stick individually and test.
Check CPU socket, look for bent or damaged MB pins closely, take picture and upload here if unsure. Check CPU contact pads for damage.

Was the CPU bought new? Could be faulty and need returning? I'd be looking at that before changing the board as everything was working before the CPU change.

It was purchased new, I can return it, right now it's just a case of replacing SOMETHING and seeing which part is buggered. Everything was working perfectly before CPU change.

The Peerless Assassin is more than enough for a 7800x3d. I was using the same model (albeit the ARGB version) on my 7800x3d and it kept it cool while running on my motherboards (same board you have ordered) silent profile. Many on here are using them on 9800x3d with great results. It's only cheap because Thermalright makes and designs their coolers in house unlike most others who outsource them to other companies. They may be cheap but the performance is outstanding for the price and they get within a degree or two of Noctua's overpriced efforts. Unlike most other cooler brands Thermalright have been around for decades and have always been known for high performance coolers at very reasonable prices. The first pc I built back in 2004, a AMD64 3400+ on socket 754 had a Thermalright cooler which was the absolute best at the time, a XP120, beast of a thing it was.

When you get your new motherboard you need to use slots A1 and B1 (first and third from the cpu) for two sticks of memory. Update the bios to the latest version as well as there have been many compatibility fixes since launch. You will need the latest chipset driver as well. Before swapping boards you may have to do something with TPM as it will probably throw a hissy fit when detecting a completely different motherboard, unless you are doing a fresh install of windows then it's irrelevant.

Thank you yes the value of the TR PA is special, glad you think it's enough (saves me MORE cash!)

A1 and B1 ?? OW crap have I been doing it wrong haha on my GB GAMING X AX I swear it says use A2 and B2 ? (2nd and 4th from CPU position)

The Asus B650E-F uses different slots to your current motherboard which is why I stated which ones to use when it arrives.

Very appreciated otherwise I'd likely have just done what I have always done
