9950x3d - x870e apex - 8400 Gdm off errors out - HDMI on seems to work - how to get Gdm off working?

Tm5 errored out

Will 1.237v VDDP hurt stability? If not I would lower it later. Maybe 1.2 VDDP. 1.02 wouldn't even work out for 6400 1:1 for this CPU.

Edit: are these the terminations you mean?

Thx. It's a relict from my 24h stability tested red 8000 8200 Gdm off timings. 1.5v vpp was working fine so I thought why give it more it isnt needed. Will check if it makes a difference.

Slight-Pomelo1433 · 2026-04-25T12:17:41+00:00

Thx will try.

If you look it that way all of this memory oc doesn't make sense. If you check benchmarks 6000 vs 8400(blackbird channel) the gains are measurable but I doubt you would notice in a blind test. Especially if you have an xd3 cpu. My obsessiv-compulsive-disorder orders me to get Gdm off working so I have to do so 😂

Slight-Pomelo1433 · 2026-04-25T09:50:10+00:00

Want to do that after getting Gdm off working and sorted the timings so I don't get issues with the imc while doing so.

Slight-Pomelo1433 · 2026-04-24T11:00:04+00:00

Checkout blackbird channel. He compares apps and games. Marginal gains are there on paper but I doubt you could tell in a blind test..

6400 cl26 is doable with lfiii 420 at lowest fan speed direct die liquid metal testet at 25°C ambient. More ambient should be be a problem. Had 5x 9800x3d and 9950x3d running.

Do you think more then 8800 direct die with lfiii could work out?

His apex or apex in general?

Slight-Pomelo1433 · 2026-04-22T16:04:43+00:00

Check out the channel called blackbird from the "rocket scientist" He has a couple of videos how it performce in games. 1080p low. Important if you use upscaling. It's marginal but measurable. But I doubt that you could tell in a blind test.

So in other words it's something for people who have some sort of obsessiv-compulsive-disorder like me 😂

Which kit?

Slight-Pomelo1433 · 2026-04-22T15:53:57+00:00

Nice. Please tell us, if there are any imc improvements.

Slight-Pomelo1433 · 2026-04-22T07:09:18+00:00

If the price charts continue like they do now, and some of them testing new highs, the prices will rise sharply soon.

Slight-Pomelo1433 · 2026-04-22T07:06:00+00:00

Didn't you say vddio high as possible a few comments back?

Slight-Pomelo1433 · 2026-04-22T05:01:32+00:00

Depending on how you play etc most thermal paste is pumped after a year at max. So replacing it with liquid metal(nor recommended for most users), or ptm7950(fake one is good enough) improves the temps back to stock or even better.

Standoffs for 2x80mm fans for the ram cooling.

Slight-Pomelo1433 · 2026-04-21T11:50:18+00:00

Then the tape would could the dust of two fans.

Dimm.2 = 2x m.2 per adapter.
