AMD Ryzen 7 9800X3D

After putting on the 9800x3d I see this, not sure if i should resell this 7800x3d like this or get a replacement, this is after a year+ use.

6600mhz 2200fclk use to be stable but lately it was acting weird. 6400mhz 2200fclk is fine though.
 
Hmm yes mine is very toasty indeed, gets into 90 degrees within a few seconds (?!) of a CPU-Z benchmark... then back down to 60ish at idle.

This is with a -40 offset... what the heck. I assume I've just totally failed with mounting the heatsink... but any other ideas?

That does seem odd, I've just booted up for the day and I'm currently idling at 38c.

To try and do apples to apples as much as possible this is 30sec-1min into a CPU-Z stress test. (I'm running stock, no PBO no undervolt currently for reference)

Thanks @DigitalTwisted.

Hmm doesn't sound good... got to 95 in a second just 'preparing shaders' for Hogwarts Legacy… oh no! :o

Edit: yup ramps up to 90s within seconds... so certainly not a fan RPM problem.

It’s probably been discussed to death, but what does this actually mean performance wise?

Max Memory Speed
2x1R — DDR5-5600
2x2R — DDR5-5600
4x1R — DDR5-3600
4x2R — DDR5-3600

Is installing 4 single rank DIMMs going to be worse than going for 2 single rank DIMMs? Judging by the reduced speed it very much looks like it, but I suspect there’s more to it.

Also there’s the MoBo topology which might play a role here as well, but this topic seems to be effectively ignored by both the CPU and MoBo manufacturers.

The internetz seem to be unaware of what it actually does, lots of assumptions and contradictory conclusions. Lack of any official guides adds to the confusion.
 
Yes I think you need to stay away from 4 modules so get enough RAM to last you in 2 modules. All 32GB modules (64GB kits) and 48GB modules (96GB kits) are dual rank. 2x2R is fine because it seems to get close to the maximum speed supported by the memory controller anyway.
I went for 2 x 32GB 6000 M/T CL30 as it is the most cost effective option. My friend went for 2 x 48GB 6000 M/T CL30 both are solid options. I personally think 32GB won't be enough soon and it would be a shame to have to replace the existing RAM.

Agree, I've had a very easy time with 2x32G 6000 CL30 kit
 
So, 45-46C idle seems cold enough. Coolant temp of 32C.

Put some artificial load on using stress and the temperature tops out at different temperatures based on power profile:
- Low power: 55C
- Balanced: 82C
- High Power: 81C
(Which I find odd - Possibly some bug with KDE's power profiles)

But throw some real load at it (C++ compilation of custom Firefox with VAAPI extensions) and the core temperature will bounce between 85C and the low 90C range. The clocks definitely slow slightly as it reaches the 90C range. The coolant temp barely gets above 35.1C though, even 10 minutes into compilation.

I guess you're referring to daisy chain vs T?

It's pretty irrelevant because as far as I know, no motherboard manufacturers are releasing T topology boards for DDR5, they're all daisy chain.

I'm not sure if T is just too expensive, or complex, and someone correct me if I'm wrong, but as far as I've found they're just not being made.

The discolouration on the pin pads? The mark on the key cut-out? can you clean it with some Isopropyl alcohol?
 
HappySheep said:
the discoloration yea I tried isopropyl but 0 difference, the other bit is just thermal paste

I would contact AMD but the trouble is in asking them if its normal or not you can't tell them about how you used to run 2300Mhz FCLK and now you can only run 2200Mhz.

Those pads are gold, i think, there will be some heat going in to some of them and maybe with some age it is normal for them to change colour a little, maybe what you need is a materials scientist :D

It could be worse....
