Finally managed to modify the AMD RX 5700 with 16GB of VRAM, I used the PS5s Micron RAM as I have tons of spare boards laying about.

This required alot of VBIOS editing to even get post output, I then ran into an issue with the GPU crashing as soon as windows loaded a driver.

That was fixed with some more VBIOS tinkering(mc init tables etc)

I had initially tried this with Samsung RAM but it would not work at all and that reminded me, this card was Micron 8GB at stock and there's supporting parts such as resistors etc on the PS5 that prevents a Micron to Samsung swap but allows Samsung to Hynix.

So Micron it was, all works, ReBAR works, post is fine, AMD drivers dont screech about the heavily modified VBIOS.

Mission success!

Will update with more info later but tonight, I'm tired.....

Yellow or red square for 9800x3d application, I live in a very hot area and even with per core undervolt my cpu still gets “hot” so any degree will help, that is why I am installing PTM but I wonder how small or how big of a square I need to go, also is the consensus on freezing it before cutting to make it easier?

So from my tuned 6400 gdm on to tuned gdm off I had to loosen:

Tras +1 - 31 tras is weird could've set to 126 but eh I like low numbers and 31 works. 30 causes issues.

Trrdl +2

Twtrl +1

Trfc2 +1 -might loosen more but seems good for now

Trfcsb +3 -might loosen more but seems good for now

Rdscl +1

Trtp +1

Trdrdsd+1

I have also minimised voltages so 1.3 soc is unfortunately needed here but my fclk 2133 doesn't care at all so it's fine.

I've tried for CL26 with gdm off using high voltages but my memory was not happy at all.

Also I've found that tuning with gdm off @6400 64GB greatly increases the risk of corrupted files lol I was able to fix them all as I regularly scanned throughout the tuning process. One time I logged into windows the screen flashed grey with lines everywhere😆

56.8ns not too shabby for 64GB standards was hoping for sub 56ns but that's just not possible for my setup. Latency killer was not used as my budget motherboard doesn't support such features.

Passed 30 mins of vt3 ycruncher with 18.5gb dataset iterations consistent 1.21 * 10^10. Going to run a full 4hrs of ryzen3d and later 4hrs ycruncher all tests... afterwards OCCT+Karhu. If those all pass, what should i look into improving upon?

also to note, vSOC is currently set to 1.15v, this is an old screenshot

I have changed my 6900 XT pads with Upsiren UTP8 and repasted it with Thermalright Helios V2. But as you can see in the first picture the cooler block doesn’t touch the VRM. I hope to not fry the VRM of the GPU. Also I don’t want to unscrew the GPU cuz applying the Helios was cancer AF.

I kept the original pads in case something wrong happens. Sadly I didn’t take picture of this before applying putty but I think the pads were thinner than the putty.

I usually run this GPU with a nice undervolt, 2450MHz@1085mV resulting in 190-230W@65-75C hotspot depending on the game.

Should i buy ROG Crosshair X870E APEX or the ROG Crosshair X870E Dark Heẻo ? I have overclock ram

Hi, a few months ago I shared my concerns about the BIOS mod for the RX 9070, and after doing a lot of research, I was surprised to find that the VRMs on the 9070 are actually quite oversized, so I decided to go ahead with the mod without hesitation.

I installed the RX 9070 XT Reaper BIOS on mine, since it seems they share the same PCB and VRM configuration.

It’s drawing 320W with a -115 UV, and the hot spot is around 78 degrees.

A score of 7105 on Steel Nomad is on par with some stock RX 9070 XTs. I’m including the HWinfo data in case you want to check the amperages and the card’s total power consumption.

What do you think? Is it safe to use the card like this for an extended period, or should I lower the power consumption to around 280W+?

I've been on a mission to build the ultimate efficiency system for long Black Desert Online gaming sessions, and I think I've found the holy grail of efficiency. The goal was simple: sub-250W overall power draw with zero performance loss.

After weeks of careful tuning and stability testing (passing Cinebench R23 / GPU Stress Test), here are my daily driver settings:

CPU: AMD Ryzen 7 7800X3D

• PBO Limits: Manual (PPT: 72W, TDC: 90A, EDC: 120A)
• Curve Optimizer: All core -35 (Rock solid stability)
• Temps: ~65-68°C under load (sub-70C during gaming)

GPU: RX 9060xt 16gb GPU (Showcasing my results on image #0)

• Tuning: Undervolted & Overclocked
• Core: 3056 MHz @ 939mV (Yes, sub-1V daily)
• Power: 160W full load
• Temps: ~63°C (Hotspot 84°C)

Results:

• BDO Performance: Solid 200+ FPS (100% GPU utilization)
• Total System Power Draw: Sub-250W while gaming!

The system is practically silent and runs incredibly cool. This is the definition of "Silicon Lottery" plus careful manual optimization. I'm especially proud of getting that GPU stable at 3056MHz below 1V.

Check out the BIOS settings and in-game performance in the attached images. What do you guys think? Anyone else running similar extreme efficiency profiles?

TL;DR:

Seems stable, looking for any guidance or feedback on where to go next.

Looking for long term daily stable OC, but I also went delidded for the first time.

So it would be a shame to not make use of that.

And really really would need a fool proof guide on CPU OC.

------

Didn't get quite the engagement I was hoping for on a previous thread and I still have no idea what I am doing.

So I had to resort to a lot of chatgpt and getting bits and bobs from various guides. Overall though, I struggle to find any complete guide, nevermind one that is idiot-proof.

There seems to be a lot of conflicting information, or I just don't get it.

System specs:

custom water loop
delidded 9950x3d on liquied metal
Trident Z5 Neo 2x32GB - hynix M-Die - 30-40-40-96 DDR6000 (also water cooled)

I tried booting with ddr6200 and TCL28 but both individually or together caused errors and I don't know how to get them stable. The latency gain and bandwidth seemed somewhat minor compared to the voltage increase needed, so I decided to go back to ddr6000 and TCL30 and try to make that more efficient instead. That seemed to require a lot less voltage, figured less might be more, especially for a long-term stability goal.

Not sure how much improvement can be had here? Judging by the low voltages i reckon higher memory clock and/or lower TCL should be possible, no?

I Ended up with the timings in the screen.
9 hours TM5 ryzen profile, 8 hours VT3+FFT. No WHEA errors.
Seems stable, also at 1.05 VSOC though I only tested a few hours with that. 1.05 seemed low,so I walked that back one step to 1.10 to have a bit of a buffer.

As it turned out the reason I ended up getting this rig in the first place was simply low CPU voltage. Could not get a boot and constant random crashing after a few years. All I had to do was increase voltage... Rather not repeat that again.

LLC level 5
cpu and vrm spectrum spread disabled.
crosshair tweak mode 2

I did not do any dedicated CPU OC except for setting PBO to enhanced at level 2 thermals(80 degrees). I was hitting TDC limits at like 60 degrees in linpack extreme which I thought was weird. Now, in linpack, it hits around 75ish degrees at 194A TDC, 208A EDC. 45k in Cinebench R23.

I suppose the score has more to do with the delid than anything else? Ran a sweep of corecycler with VT3 at 6 minutes per core (3 hours), no WHEA error. No Curve Optimzer or anything else. No clock stretching that I can tell.

Could not find a good (and simple) guide to do any CPU OC.
Most I dismissed as I they recommend setting motherboard limits. Unless something changed since my last time, that is dangerous advice, and certainly does not help longevity.

Skatterbench has a post that is recommened bt that was way to deep for me and also seems to just remove limits. Didn't strike me as a daily safe guide?

And related to my previous post, I had audio crackling before but I think I fixed that now, turned out that the speaker audio sampling rates were not aligned. Needs a bit more testing but I haven't heard it since aligning them. Doesn't seem to be related to the memory overclocking.
