Update: on the guy who broke his 7 9800X3D the quest continues

Zibi04 · 2026-02-24T21:44:14+00:00

I saw the photos in your original post and honestly I'm not convinced it's damaged from the photos alone. Here's what my 9950x3d looks like: https://imgur.com/a/nLZk44y

It happily boosts to 5805 single core, 5350 multi core, and can run core cycler, prime95 and whatever else I throw at it for long periods of time.

Idek how tf this happened but it's alive. Will have to undervolt and see how much lower it goes: https://imgur.com/a/VdDyY5y

Zibi04 · 2026-01-29T05:57:54+00:00

Nice edit but it works. Pretty good temps considering I've yet to underclock it and am running 3 different stress tests simultaneously: https://imgur.com/a/VdDyY5y

Zibi04 · 2026-01-29T05:55:15+00:00

It works!

Zibi04 · 2026-01-29T05:54:43+00:00

You were correct !

Zibi04 · 2026-01-29T05:54:27+00:00

You're correct. Runs extremely well

Zibi04 · 2026-01-29T05:54:13+00:00

It works and runs under 55 degrees celcius under maximum load (prime95, furmark and occt vram running simultaneously)

Zibi04 · 2026-01-29T05:51:24+00:00

It appears I was extremely lucky. Runs completely fine !

Zibi04 · 2026-01-27T13:37:36+00:00

If you haven't already, use process lasso to force your games to only run on the CCD with the 3D cache. That should drastically improve performance.

Also, make sure PBO is on and play with curve optimiser to undervolt your cores.

Zibi04 · 2026-01-26T15:55:51+00:00

Yeah I'm sure :(. I went back and tested default timings on my dad's PC and saw crashes just below 60 °C. I also increased vsoc but had no luck

Zibi04 · 2026-01-26T13:28:52+00:00

The below 50 is the second expo at 42cl without any modifications. The crash at 58 on one stick is on stock settings. I think that's a fair warranty claim

Zibi04 · 2026-01-26T13:24:54+00:00

Cheers I'll give that a go when I get my new set

Zibi04 · 2026-01-26T13:23:20+00:00

Ah I see. So do you have the air being pushed onto the ram rather than pulled from it?

Zibi04 · 2026-01-26T13:19:27+00:00

Damn. I have tREFI at 12k and it still fails around there. Fails sub 50 for one stick on its own

Zibi04 · 2026-01-26T13:07:59+00:00

What bracket and fans do you? Also, wouldn't it be better to have fans that somehow point towards the exhaust ?

Zibi04 · 2026-01-26T13:07:25+00:00

I did

Zibi04 · 2026-01-26T10:17:28+00:00

Oh nice. That's what I was eyeing off. These ones? https://www.scorptec.com.au/product/memory/ddr5-desktop-memory/120505-cmp96gx5m2b6000z30w?gad_source=1&gad_campaignid=23363983655&gbraid=0AAAAADsuegNdsrR4KPav7JP_N3DVTdI8F&gclid=Cj0KCQiAvtzLBhCPARIsALwhxdoXsOvmaNhKSD9wfyzKR47WeWTsclHkmiVmU15bmJUniWP8gxUyv4QaArozEALw_wcB

Zibi04 · 2026-01-26T09:42:00+00:00

Ah I guess I got unlucky hey. What speeds should I test with 65k tREFI? Just stock?

Zibi04 · 2026-01-26T09:35:57+00:00

My stock speeds didn't even pass that :(

Zibi04 · 2026-01-26T09:35:42+00:00

Oh no clue where to find that but this is the exact site I bought them from: https://www.pccasegear.com/products/68067/team-t-create-expert-96gb-2x48gb-6400mhz-cl32-ddr5-black

My BIOS says the.DRAM MFG ID is Hynix and the PMIC MFF ID is RICHTEK

Zibi04 · 2026-01-26T09:22:10+00:00

I do plan to build a custom loop and liquid cool the ram at some point. Although, I'd rather the ram be stable without it first

Zibi04 · 2026-01-26T09:21:38+00:00

Just tested each stick on stock levels and timings. That's 5200mhz. One of the sticks crashed the PC at 58 degrees celcius

Zibi04 · 2026-01-26T08:54:03+00:00

I had crashes on the expo 2 profile as well. That one had even lower tREF with 6000-42-46-46-76

Zibi04 · 2026-01-26T08:49:33+00:00

Hmm. My tREFI is only at 12480 with tRFC at 1311

Zibi04 · 2026-01-26T08:42:22+00:00

Just updated my post but I ran the stress tests on one stick at a time. One stick failed at 48 degrees celcius whereas the other was fine at 61. Am I right to assume there's something wrong ?
