Well this was wrong. I foolishly thought the riser card was needed to connect to the BTF port but completely not needed. 🤣 It's for using to connect to a BTF board. The BTF to 12v2x6 cable works flawlessly. Near perfect 12v under 800w load with great per pin distribution.

I experienced similar behavior to all of this on the Precision 7770. I do believe it is related to CPU/GPU power contention and NVIDIA Dynamic Boost. I observed the behavior on both Windows and Linux (specifics were a bit different between the two). I never really figured it out, and it was part of what made me stop using that system as my personal "daily driver". And yeah, battery drain while gaming was also a thing that I observed when compute load on both the CPU and GPU was very high. I rarely game for more than like 90 minutes in one sitting so I never came close to actually draining the battery.

Thanks @JadeRover for the response, thats what i suspected it presented both, I had initially scoured the "interweb" for 8770W cables, but discussed with GuitarG and found 8770W were wired different, which is a pain as if 90% of the wires are same and just a few are different it might have been viable "small" mod to make it work. 40Pin EDP seem available so the screen end is easier (relatively) I did catchup with DevilAngel on the 8770W post in the message, he used TaoBao to get someone to build a cable. I'm yet to work that site out with success. We seem to have alot of the pinout detail its just getting someone to make one.

It's not a Xeon E5 2000. It's the unlocked ones, people from NBR overclocked them to 4.5GHz but didn't give any BIOS settings. Even with the 4960X I can't get it stable at 4100MHz. Extra turbo voltage doesn't seem to work

Also works on my 3080 Ti. This is 225W. Also tried 200W, which got me ~14850. For some reason the CPU starts throttling when the GPU can draw over 150W. The same thing happens if I shunt mod. At 150W GPU the CPU scores is 10800.

As Mr Fox said those CPUs was locked down at that time. Those Server CPUs aint gonna let you overclock them but so much. When i had my P570wm running i had a 4960x running at 4.2 ghz all core with XTU. Eurocom had a unlocked Bios but didnt need to use it because if i tried to overclock above 4.2 wood crash. You may not be able to get dat chip running more than where you tested at....

I’m doing great! I hope you and your family are all good as well! Im still out of work, sleeping until 11am some days and hustling junk cars, hard to believe it’s been about 6 months now. Life is good! I started playing with Mvolt+ tonight, although I already had it, I haven’t really dug in to it. I just got the new one though, amazing app. My 5090 Astral has a pretty low Xbar like 2,490Mhz, so I focused my tuning there to try and gain some performance. I kept the card all stock for now 600w pwr, 0% voltage slider, auto fans, default memory +0 and default core clocks +0. I started adding voltage to my Xbar and saw performance degradation and Xbar even went down even lower lol. So then I started taking away Xbar voltage, I reached -20mv and the score improved slowly in Steel Nomad DX12, then I began adding Xbar clock frequency and reached +164. So I settled on a 15,500 Steel Nomad score on my 5090 Astral which is amazing. All stock power limit of 100%, and 0% voltage slider, no memory or core overclocking, or undervolting at all. So just with Xbar clocks going up. Then I undervolted the card to 900mv, OCed the memory +3,000, and it hit its 16,001 and even idling at 10 watts on the desktop. Not even really pushing the card at all. Great daily setup for air card.

Went into Microcenter to add the warranty. Brought the card with me and talked with the tech and manager about the artifacts. Had the video on my phone showing it happening on the desktop and in games. They said not normal and wanted to swap the card. They only had the demo unit they had on display behind glass left but offered that card. They took the card, put it into it's retail box and swapped the GPU and added the 2 year warranty. Just got the card in and it's significantly better and no artifacts yet. 57.6% ASIC, not a lottery winner but not a dud at all. My previous card would crash at 3300Mhz in GPUZ. This card does 3400Mhz and uses 1085Mv max. I'm just happy to have a card that isn't artifacting out of box. Got my adapter delivered and unfortunately, my Apex board blocks the cable. The heatsink gets in the way. Ugh. So now I'll have to use a small offset or go vertical or something. Not my favorite but it seems no choice.

I have seen weird glitches like that with some of the 621.XX drivers and I have seen it when undervolting GPUs. I am assuming it is with the GPU running stock with no tweaks like undervolting or overclocking. If it is bone stock, have you tried an earlier driver branch, like 610.XX or 596.XX to see if the behavior is the same? If it is the same across several driver braches, test with a different monitor and different HDMI/DP cable. (I have an ASUS 4K 120 HZ IPS display that has all sorts of weird issues with various GPUs to the point that I only use it as an office TV now.) If it still persists after all of those things then something has to be wrong with the GPU.

Have any of you had weird artifact/purple like boxes flicker in your displays before? I can’t figure out what is causing this issue on my new GPU. Tried DDU. Tried swapping cables. It always seems to come back. Sometimes a restart takes care of it for awhile but it reappears randomly. Even happens in games which shocked me as I figured maybe it was an idle memory issue. Sorta stumped on it. I’ll upload a video later if I can

I purchased a Lenovo Legion 9i 2025 two months ago. Compared with the unit reviewed by Notebookcheck (NBC), the only difference lies in the GPU: my machine is fitted with an RTX 5090 LP. For the rest of the hardware — RAM and SSD — I am working to upgrade them to the maximum supported specifications. Most notably, I intend to bring the memory up to 64 GB × 4 = 256 GB. I have finished preliminary testing and am running the laptop for real‑world daily use. I plan to run a full retest once the 256 GB RAM build is complete, and I will release my review report then. On the subject of the display as you mentioned: every SKU comes exclusively with a glossy panel. The sole differentiator for the screen is support for glasses‑free 3D. I deliberately skipped this gimmicky option, as I have no use for the feature. The port layout has been fully verified: two Thunderbolt 5 ports plus one Thunderbolt 4 port.

This is just really sad. The 5090 couldn’t be exported but a 84gb card can? Makes no sense. This card is easily better for AI given the vram and same core count. The slightly cutdown bus likely won’t hinder it much at all.

UPDATE: I don't know what it is that I've done, but now it's only downclocking to 2.5ghz after a few minutes of gameplay. Exiting a game brings it back up to the usual clocks, around 3.6ghz. One other thing, I noticed that my battery is being depleted as I'm playing. It not downclocking to 0.8ghz is nice, but I don't know if it's normal for the battery to deplete rather quickly as I'm playing...

Here is where the 5090 chips go. Almost all of them for workstation cards for the China market. I can't understand why this is better than feed China with vanilla 5090's. The US government banned 5090 gaming cards for the China market, but this is so much better. Oh'well, none can really stop Jensen from doing business with his preferred friends. This is just disgusting. “I have a ton of concerns that neither the Commerce Department or Nvidia is doing the due diligence needed to ensure that the licensing terms are being followed,” former China director for the White House National Security Council Liza Tobin told the publication. President Donald Trump banned the export of Nvidia AI GPUs in April 2025, even those customized to meet the performance ceiling Washington set for AI processors. The president reversed the decision late last year in exchange for a 25% cut of the sale... NVIDIA's RTX PRO 5500 is China's most wanted GPU, and almost nobody is getting one soon So why is China buying a workstation card instead of a data center accelerator? The RTX PRO 5500 is a Blackwell-based GPU with 84GB of GDDR7 memory that complies with US export rules, which bar NVIDIA's B300 from China and put its H200 under case-by-case licensing, making it one of the most powerful NVIDIA chips Chinese companies can still legally buy. Btw. Jensen couldn't resist. Even on the private he prefer chinese. Doing business and pleasure with chinese spy doesn't come as a surprise to me. Nvidia CEO: Jensen Huang admits to breach of trust, board of directors launches investigation The potential target: high-end AI chips The New York Times added that Alice Huang had been specifically recruited to gather information on Jensen Huang. This was part of a larger Chinese effort to learn more about US AI chips and potentially persuade Nvidia to make its most powerful products available to China.

I've just disabled Dynamic Boost. No change, it just throttles to a dreadful 0.8ghz. HWinfo shows no thermal throttling on all cores, but Package/Ring Power Limit Exceeded is Yes on all cores. I've tried using Throttlestop, but it hasn't worked. I've tried using lower PL1 and PL2 figures, I've tried using higher PL1 and PL2 figures (as in the screenshot.) The weird thing is, when the game's running in the background (not active window) the power throttling doesn't occur. After the frequency stabilises with the game just in the background, going back into the game puts the frequency back to around 2.5ghz then 1.5ghz for a few moments, and then it goes to 0.8ghz. These are the limit reasons.

This is probably dynamic boost as your GPU and CPU share some headroom, try turning off dynamic boost (fairly sure it's in NVIDIA settings) and observing your CPU clocks under load. failing that, check hwinfo and see what limits are being triggered for the CPU

Nice work

Nice to see you, brother. Hope all is well with the family. With mVolt+ there is no longer any need to cross-flash BIOS, shunt-mod or use EVC2 for voltage control. You can change all of those things with software now... just a portable exe file does it all. And, now you can also run the latest DLSS and frame gen on GPUs NVIDIA said "do not support" DLSS and MFG. Yup, on something like a 3060 that would barely manage 30 FPS at 4K now you can do 100+ FPS, thanks to talented modders finding ways to beat and defeat the Green Goblin's lies and shenanigans. DLSS Enabler or DLSS5 Manager even let's you run DLSS on some AMD and Intel GPUs now.

Hey everyone! It’s been a while. Still rocking the same rig. One useful thing about the test bench is, we can move it to the living room! Ryzen 9950X3D2 (2200fclk) (2x16GB) Gskill DDR5 6000c26 kit @6400c26 with 1.500v VDD. X870 Strix motherboard 5090 astral. I run a Curve Optimizer per core on my 9950X3D2 which is tuned perfectly on each core. Some cores handle a -18 undervolt, and others can do a -33 undervolt. I found this worked best rather than setting a per CCD. I have considered water cooling my 5090 for the long haul since GPU’s have changed so much, but with the way they seem to be very limited inside the USA and even RMA issues being reported, I figured I probably won’t mess with any modifications at all. I’m not going to shunt mod it or even run the higher TGP bios. Probably not worth the risk with prices being what they are and at all. If it were a 5090FE that would be hard personally because they really need more power to compensate for the much softer “FE” bios. Anyways, 5090 Astral gets it done very well. I’m pretty sure it’s about 7 to 9% faster than a FE stock VS. stock.

A little update to my upgrade on the Dell Precision 7560. I finally installed the RTX A4000 on it. Gaming feels like a dream now... except now the CPU power throttles a lot. I took a look at the CPU on HWinfo, and it's really just power throttling. It's not reaching 100c at all. I am using a 240w charger, so what could the problem be?

Probably did one of the most idiotic things I've done in a long time lol. I went to Microcenter the other day and took the last 5090 Astral 20th Edition they had on hand. The catch was you had to buy the entire ridiculous bundle. I'm not even kidding when I say I was shocked at the size of the boxes and it looked ridiculous packing it into my SUV. The price was just stupid. But I figured I could sell of the extra parts. I also sold my 5090 D HOF XOC locally for $6500 and it took a lot of the sting out of it. I sold off the motherboard and PSU and am likely going to keep the case because you can use it as a open air test bench which I've always wanted. This thing looks quality and I can use it as a vertical open air case too. So while I have no use yet, I plan to eventually build a nice test bench setup and this case will fit the bill. My biggest concern was I wanted a warranty on my 5090, and given the "D" model, I thought it might be hard to sell in the future locally. The reason I wanted this card was the dual power input. I bought the adapter and the adapter cable from China, so I can use the card with dual 12v2x6 inputs and no need to use a stupid BTF board. It also locked in my warranty for another 3 years and at the crazy price Asus charged. I passed on the Microcenter warranty, but I'm now wondering if I shouldn't go back and add it. I might even take the 3 year warranty, especially since things like mvolt exist now. Downside, the card is kinda meh. Like it's barely better than my 5090 D HOF which was already a terrible bin. Still need to really test it once I get dual power input on it and can push the amps. Upside is that it seems to undervolt like fairly well. I am able to run +350 at .9v for around 2850mhz. It shaved off around 100w for almost identical perf. Microcenter did have an already built unit, so there is a card in there technically I could swap for. But honestly, I don't just benchmark all day long, my time that I have I mostly hit up the games so I'm not upset the silicon is mid at best. The card is just ridiculous sized too. The cooler is insane. It has the 800w vBIOS by default, but of course you can't use that until you use the adapter/cable or BTF connector. Of course mvolt takes care of that too.

So I was right and you made some kind of mule 😅 horse ( core from P5200 ) and donkey ( P4000 card )🙃 😎 You made new card , lets call this mule P4600? 😅

@Eban thank you for pointing that out. I have checked and is not bloated, it is fine. There is a shadow of the white wire that it is covering it, makes it look oddly. Almost 2 weeks and the AC ADAPTER is still working well after the repair.

It will be interesting to play with. It was $650, which was more than offset by what I sold the last 270K and 8400 Kit for with money left over. Now I am considering whether to keep or sell my spare G.SKILL 8400 kit. It's collecting dust, but there is an element of apprehension about selling my only emergency backup DDR5 kit. I may never use it, but if I needed it replacing it would be difficult. Hard to source and super stupid expensive. I agree. I love doing that as well. It brings them a lot of joy and what I can give them is always a lot more special than whatever cheap crap box they would buy off the shelf. It was the below combo. Certainly not going to do anything remarkable, but for her low-cost gaming rig it is more than adequate. It was a stubstantial upgrade in CPU and memory performance and plays nice with her 1080 Strix GPU. The kind of games she plays there is no reason for anything more powerful. She is mostly into indie titles and stuff like Fortnite and PUBG. Windoze 11 just wasn't playing nice with the old X79 setup. But, it still works flawlessly on Linux. The 5500F Cinebench score is several thousand points higher than what the E5-1680 V2 (2013) and DDR3-2400 was capable of with its max functional overclock. Just using the included Wraith Stealth cooler on the 5500F, Cinebench temps were only about 79-80°C. I've overclocked it a bit for her (4.6GHz all core) to keep things running crisper.
