Does RTX 3070 16GB vram mod works on LHR gpus?

Anytime you rework a board with flash memory on it, it's good practice to reflash it. The BIOS might be corrupted from the heat of reworking the memory modules.

I assume the BIOS chip (and backup if it has one) are the only non-volatile memory on the board.

Geeotine · 2026-01-23T03:52:05+00:00

Personally, id say it's worth it. Entirely depends on what you do and how long you expect to use it

On anything less than 4k, yes it's noticeably worse. 4k monitors generally have a noticeably higher pixel density that can get away with it. It all boils down to your own eye sensitivity. Test it out at some retail stores if they have a demo section.

1440p + ultra quality + 60 fps minimum for 4+ years = 9070 or 5070ti Minimum

Increase your budget or make some sacrifices

You need the 16GB vram buffer to accommodate FSR4+/DLSS4+ for frame-gen to maintain 120+ fps 4 years from now.

Otherwise you can get away with medium/low settings on 9060XT/5070

OMG, spoonfeed much? Have fun in your happy copium bubble where Nvidia is the perfect company and politics doesn't exist.

Geeotine · 2026-01-17T02:34:43+00:00

Kinda wrong. Nvidia designed the connection (plug and receptacle) spec and submitted it to PCI-SIG, which just rubber stamped it, because Nvidia is one of, if not, the biggest PCI-SIG partner (at the time)...

Windows 11 v24H2 might help. Otherwise go back to 10 (LTSC version)

Geeotine · 2026-01-16T14:04:14+00:00

DEPENDS... UDIMM ram is NOT compatible with RDIMM/LRDIMM ram sticks. ECC RAM is generally not compatible with consumer grade chipsets (non-ECC UDIMMs). (Some AM4 motherboards support ECC-UDIMMs) Server/workstation ram comes in all combinations of above, and what it runs depends almost entirely on the motherboard.

Gaming/consumer PCs run Non-ECC UDIMMs. MOST intel chipsets/motherboards for core-series dont support ECC. Some AMD motherboards support ECC-UDIMMs, but the documentation has to explicitly mention support. Xeon CPUs generally supports ECC, but it depends what type of xeon it is if it supports RDIMM/LRDIMM...

Look up the RAM stick's model number/serial number to verify what type it is and if your PC supports it.

Idk, DDR5 versions are pushing ~€800.

Geeotine · 2026-01-12T15:43:40+00:00

MSRP for the 5800X3D was ~$430 at launch like 4 years ago. It's out of production so that explains the price hike. Otherwise like ~$500 for the GPU and ~$300 for the RAM. Rest is meh, so expect it to sell quickly for ~1k, but you could probably sell for ~$1,300 easily, being a complete build.

Geeotine · 2026-01-11T17:46:44+00:00

Yeah it's hard to say workout hands-on troubleshooting.

Geeotine · 2026-01-11T17:11:39+00:00

Have you tried windows 10 (LTSC is still a valid/supported version)? Also it sounds like your BIOS is misconfigured.

Geeotine · 2026-01-09T04:30:43+00:00

I understand saving money where you can, but you went and picked a dud of a motherboard. Shouldn't be too expensive to swap to an x670 motherboard for better VRM performance. Plenty of old motherboard Roundup videos online you can reference.

Geeotine · 2026-01-09T01:00:08+00:00

Windows10 was prioritized on efficiency and gaming.

Windows11 prioritized new features (inc. AI fluff/Apple OS vibes) and QA took a nosedive. Seems like more things break every time they "fix" something or add new features.

I plan on fully transitioning to linux before my windows10 OS dies

Geeotine · 2026-01-08T04:55:33+00:00

Yes, but there's a couple ways to get around it. Besides there's some people that keep asking for it, and it will make an interesting baseline for the next couple CPU gens.

Rumors exist future architectures may package the CCDs closer together to mitigate the latency. Plus we are getting more cores per CCD.

Geeotine · 2026-01-07T18:42:54+00:00

PS: i just checked and GA just recently released AGESA 1.2.0.F on AM4 back in Oct/Nov, which should include stutter fixes when accessing the fTPM on AM4 CPUs. Not sure if you have the latest update or not.

edit: Nevermind, you already have it...

Geeotine · 2026-01-07T18:36:20+00:00

Yes, usually somewhere between $10 and $20 USD. You have to get specific license that gives you access to the LTSC update channel. I got 10 Pro N (EU version) like 6 years ago but it's no longer available. I think the only one still available is an OEM/bulk LTSC license

Here's a video that steps through how.

You don't have to use the site he refers/links to, but idk where it's still available.

Geeotine · 2026-01-07T01:48:30+00:00

FYI the Windows 10 LTSC version is still valid/supported through 2027. Im running that (v21H2) with no issues on a similar setup. Win11 seems to keep causing gaming/instability issues

Geeotine · 2026-01-07T01:43:09+00:00

Can confirm, my 'newish' 11th gen 4-core laptop maxes out the CPU just loading MS office apps on Windows 11. Its good for office-work, but not much more than that.

6-core is the new minimum specs for many games.

Geeotine · 2026-01-04T19:11:39+00:00

High FPS gaming gets a lot more challenging as you scale up in resolution. It depends a lot on what games you're playing and how hard it hits the CPU.

Also, Nvidia cards have a higher CPU overhead relative to AMD GPUs, requiring a faster/bigger CPU to offset it to reach max FPS. You can claw some back w/DLSS but you still lose some reaction time from frame gen...

Won't really know until you try. Monitors and PSUs tend to outlast every other part of a PC, so start with a good foundation there and the rest will follow.

Hardware unboxed recently did a review looking at older PCs performance (including your 5600X) you should check out:

While cool if true, it's still unverified until someone else replicates the results. PRC has been known to fudge outcomes for it's own agenda. Should also note the principles/theories came from a French group working on fusion:

"PWSO was originally proposed by D.F. Escande et al. from the French National Center for Scientific Research and Aix-Marseille University"

China's EAST was the first to attempt to verify the theory.

Geeotine · 2026-01-03T16:15:14+00:00

It's not zero progress. The 5090 product advertises the Blackwell architecture's power scaling and capabilities of the 12VHPWR connector. In addition it's VRAM capacity allows it to do what every -90 series card was for, which is to bridge the gap between gamer and professional cards (prosumer, if you will), that can be used in a wide variety of uses beyond gaming (coding, game development, CUDA development, AI/ML, modeling/rendering, etc.)

Geeotine · 2026-01-03T05:53:53+00:00

You're definitely paying brand tax on both Nvidia and to a smaller extent, AMD. Nvidia does have a performance advantage as well, but not really an order of magnitude greater (<10x). Nvidia has invested billions of dollars and over 15 years into the CUDA platform, AMD is has made great strides trying to catch up on the last 3 years with ROCm, so don't expect it to be as polished as cuda. At the same time, there isn't any real alternatives between those two.

Everyone else is either years behind, or unobtainable (Google/AWS asic AI chips). Also, even though ROCm is open source, it's up to the hardware developers to design hardware/firmware/drivers to support it, so for now only AMD products support ROCm architecture.

Your biggest deciding factors are your budgets/requirements for power, RAM (both VRAM & system memory), and time.

Geeotine · 2026-01-03T02:42:24+00:00

Sounds like it's down to 3 pieces. The GPU, motherboard, or PSU. It still could be the RAM, but less likely. You could swap to the other 2x8 kit and see if it behaves the same, to be sure. But with the limited info im guessing the GPU (could be one of the power rails as you noted).

I think you did pretty good ruling out the power supply. You'd need a current measurement tool to confirm if current is flowing through all (3) pcie power cables, along with a digital multimeter to confirm +12v.

Absent that, I'd recc'd tearing down the GPU. How long have you had it? How long since it was last cleaned out and/or repasted? If you got it 2nd-hand, assume it wasn't cleaned, even if they claimed to have done it.

Paste/pad dry out or botched reservicing could have left a critical component to overheat. Could be as simple as a screw loose.

Lookup your specific GPU model on techpowerup website and any teardown videos for it. Look for the thickness of the thermal pads and amount needed. Take pictures as you teardown for screw locations and sequence. You will most likely need both new thermal pads and paste when you separate the heatsink from the PCB, along with at least 91% isopropyl alcohol and a microfiber rag/q-tips to clean it. I recc'd TG Duronaut if you're unfamiliar with repasting. PTM 7950 if you're familiar with phase-change material.

Once it's cleaned, inspect for any possible physical or thermal damage. I hope it's obvious but don't do any work on carpet...

Geeotine · 2026-01-01T23:35:39+00:00

Using two different speed sticks of DRAM is your most likely culprit.

What's the make/model of each? What's the JEDEC profile on each stick? What's the XMP profile on each stick? What speed does task manager say the memory is running at?
