ATAN

Hey does anyone have time to pull a fan or two? Im looking to buy two of the sunnons for a project and I returned my 7770. I cant seem to find anything but packaging dimensions for either one. I roughly remember them being square and no bigger than 50mmish either way. Thickness I dont recall...

Was going to comment something similar on that vid but I stopped caring too fast. Sff build is complete and family pc tbd later but still a nice $900 savings combined over the 7770 13700k (no e cores) + Noctua NHL-12S + + Gskill Tridentz 3600mhz cl18 64gb ddr4 Asrock z690m itx/ax (pl1 = 125w max, also no in os oc support since two bios patches ago, too bad I need the newest one) 6900xt + evga clc 280mm (been modded since day one) SSUPD Meshalishious 800w SilverStone SFX No voltage play here but there is room for another 4-7% gains if tuned, 13th gen is a smidge more efficient than 12th gen mobile before voltage tuning. I haven't done much 78w testing but to say the least, heat loss alone would be many factors less. Perf below never passed 88* peak, fresh air intake. PL1/2/BoostTime = 125w/157w/224s CBr23 2k something single / 20k multi yay (25% improvement in multi over perfect scenario 5700g/12950hx 78w in an imperfect scenario optimization wise) GB5 2150 single/ 13.6k multi yay PL1/2/BoostTime = 125w/125w/224s CBr23 2k something single / 18.8k multi yay GB5 2150 single/ 12.8k multi yay 4k Gaming is much better with my 6900xt than my 5700g or 78w 12950hx (even ran my 6900xt off the egpu dock, 0-5% perf decrease on 98% of titles outside of running in 4k needlessly maxed or aiming for more than 120/144hz) Time saved building the new pc, including removing the heat sinks off my ram because clearance, disassembling the last pc, not obsessively tuning for an ineffective 55-70w cooler, and not whining about my system, compared to the 7770, approximately 3.8 weeks. (Pc building/disassembly took a bit more than a hour total) My only complaint is that I did not attempt to diy a laptop, I threw a few days messing around with ideas but I opted to just use the meshalisous, doesn't take up much desk space, its just tall.

You want no heat? No e cores, and 65w power limit is a good start. Then undervolt to reclaim perf until "stable". Its how its designed, after a certain point the heatpipes are overwhelmed and the small heatsink, that is roughly half as tall as it could be not that it would help if it was taller, helps dissipate a bit more heat but its better suited to a 12700h not even a 12650hx let alone a 12950hx. They saw the 55w tdp and went wild. If anyone wants my throttlestop inis/power plan settings for 77w or 80w(cooler modded for sub 100c package temp) usage on p cores only that you might actually be able to run because it isnt aggressive let me know, its got 4 different profiles for four different levels of thigh pain, desktop grade(in alderlakes case, unleash the clocks!), mobile workstation grade, efficient ryzen without a cooler grade, and lastly 6800u at 35w but faster/cool/nofan/worseigpu grade pain. im salty I'm sending mine back. Just going to build a 13900k/13700k sff (slightly smaller than my 5700g/6900xt) with my 6900xt and disable all/all but 4 e cores and go ham on the oc/uv. All these laptops arent worth the money even slightly. $2000-3000 to thermal throttle via near base model workstation or 3000+ for gaming laptop that can go jet speed sound levels. i'll be doing two builds, a new z690 itx system (w/ 6900xt, old psu, and old ram) and, using my old 5700g build, a 5600x/6650xt/32gb ram family pc for less than half the p7770 as configured ($2500 w/ 45% off from what dell said) Im also selling the 5700g prebuilt i stole my desktops apu from to recoup 90-110% cost along with my two 21:9 monitors, the 64gb of ddr5 sodimm i used for 3 weeks in this tabletop(anyone interested?, Kingston Fury Impact 4800mhz cl38 32gbx2 kit), and lastly my 2 year old 5775c mobo + ram combo that I played with and unofficially broke some records at 4.5ghz with. 120-150w 13#00k here i come!

I was also experiencing this at times, no e cores no problems as well. It definitely is the difference between 3.3ghz and 3.7ghz all core load cb(could take much more but I limit it to 80w from 92w after 5 secs cuz heat) and after that I've gotten up to 15.5k cbr23 and only down to 14.75k back to back. It definitely still sucks, if I don't want to burn my legs I limit it down to 45-60w whilst undocked, I'm effectively using the 4 fastest cores unregard of power and treating the 4 slowest as effective p cores by limiting the clocks severely.

I see i see, nvidia profucts arent anythinf ive paid alof od attention to. Its been about two upgrade since i was support to alternate and trt nvidia, i couldnt stomach their practices.

Have any of you with a higher tier gpu sku tried disabling your dgpu for more cpu headroom? Just asking as I look at these other heatsinks on ebay.

You definitely have some wiggle room, I'm getting 15.2k back to back runs on just my p cores. 18k without much tweaking/tuning with the ecores, prolly could get 21/22k first run only now. Cache undervolting is the main gain source for my system. Stock vs -125 I go from 13.8k to 15.2k(can't stable -140), my core is only -140, it can do -190 if kept under 75c. On another note I kinda want the new 7900xtx more than this 7770(i like it and im still looking towards mods or if i keep it just adding more copper with a heatsink swap to the gpu version), if i return the 7770 I could build a smaller zen 4 system with new gpu or get a gpd winmax 2 in addition to the new GPU for $1000 + Tax with a hundred to spare. Desicions

Yes and that would be exactly the plan, remove base plate from heatpipe assembly and replace with a small 3mm vapor chamber and a even smaller copper baseplate (because that's not playing with fire) that could help remove bursts of heat better than a copper slab by itself but it will be limited by how much a thinner replacement could conduct (which isn't alot at all lol) and transfer to said heatsinks via the stock albiet less bent then stock (in terms of height). It would likely not increase overall thermal capacity much if anything reducing it, the thing it would help is short term boosting performance for non constant workloads, ie Geekbench lol. On the opposite end, adding raw mass (copper or alluminum) can provide short term gains as the issue was never it's ability to cool itself/soak heat but rather it's limited thermal capacity overall. To which adding small heatsinks wherever I can fit them has netted small gains but unless I was to be adding actual weight it would not be useful outside of soaking 90w for slightly longer and letting the vrm breath a bit. Not even mentioning the fact that it takes a lot of skill not to damage the VC or heatpipes themselves On another comparitive note, the 7770 egpu should still technically be faster than the average laptop for gaming as they tend to give the power budget to the GPU. So to each his own. Edit: not to mention how vapor chambers that would fit within the mounting size would have rather low thermal capacity. I'm just shooting the shits and trying to take a duece on dell as I just want 10-20 more watts sustained capacity.

Anyone with a precise measuring tool who can avoid using hillbilly western measurement standards and has a little bit of time to measure the mounting dimensions for the CPU I would appreciate it. I'll do it myself soon if I have to, I just don't have functional calipers rn. As crazy difficult and tool-wise expensive as it would be, mounting a small vapor chamber in place of the copper cold plate might give a little bit more thermal headroom. Maybe not as well as the nuc series but competitive, seeing how it uses only a small vapor chamber and small but dense fin stack. I also am looking into thermoelectric coolers for docked usage, doubt they will fit thought. Not that it's very user friendly, and honestly it's easier just to expand my custom loop and/or pull a De8aurer type move and try making a custom loop/waterblock for 2-5 7770s in cold cash, clearly I'm not that insane. Just doing the modding research before its time to commit to it or send it back, which is soon(tm). On the same note I'm looking at the Alienware/Lenovo all amd laptops, taking the performance bullet, not that I don't get the same/worse all (8p) core perf on my 7770 on anything besides single core benchmarks and games. (77w pl1 still but 3* cooler with the Honeywell 7950) vs amd apus. I just want it cooler so I'm not doing a Mobo/cooler swap in 3 years because it sat at 90-97*c most of its working life. Also it seems like it's cooler can't really sustain a few hours of heavy work at above the 70-75w range, not that I do that often. Really makes me wonder why they don't even have a single vapor chamber config for this machine, but I digress. On a brighter note, zen 4 mobile looks promising from a perf/watt perspective. If I don't keep this or get the m17 then I'll just wait again for the 3rd time 😂 maybe a winmax 3 that could offer slightly better performance on all aspects along with a SSD door on the rear. Also hp support said, in reference to the zbook fury 16 g9, I had to get the a3000 config for a vapor chamber, an $1200 a3000 that I might have to disable just to use my egpu, not the half price pro 6600m that would just work. So that's out the race, don't want a $4000 machine in which I only needed half of it. Really makes the Lenovo and Alienware 6900hx/6850xt configs look nice dispite massive storage nerfs. I've been brought down to my bare minimum requirements of 2 gen 4 m.2 slots without a SSD door(Dremel go burr), 5700g level performance, and egpu compatibility w/o funky Optimus business with my 6900xt. I'll miss the nice looking 7770 tho, only a little though. Man if they still made thin itx boards, along with the new HDPlex GaN PSUs I'll be using in my updated egpu build, I could probably make a slightly thicker but way better laptop for my needs.. If only I had a 3d metal printer.

Testing some Honeywell 7950 to see if itll help. This is a holy move that must be taken with much grace.

All I need is a third heatsink revision(really the first real one) and a loosening on the bios.

I have been considering a mod, seeing as how we have a less funky than normal copper baseplate/mounting system, why not swap it out for a random vapor chamber. Example: https://www.digikey.com/en/products/detail/wakefield-vette/VC-106-70-3/7603219 Whilst it might not help that much with overall thermal ability without some heatsinks/heatpipes+heatsinks and foam to further direct the internal airflow, it could still help with high power boosts above 100w. Ive been mentally abusing myself trying to figure out a mod to add more headroom but its seeming like custom work/soldering is neccesarry.

Will do, still have about two weeks before I have to commit to keeping it.

My 7770 w/ 12950hx, 8gb ddr5(+$240 for kingston 64gb), 256 gb m.2, ubuntu, the 2nd lowest display, and smart card/SSD door for $2500(financing at gross rates if late+ Mastercard sale + online sale = ~45% off MSRP) A little high for a no GPU system. I'm tempted to send mine back and grab one of those 16" and save the 700-500 overall. Still not exactly worth, but its a linear upgrade from say… a gdp winmax 2, which is my main alternative. Its cant really pass 40w and when at 40w this laptop smashes it by 10-30% in workloads, not that you should be doing that on the hx platform. Also it isnt worth talking about in games in the 96eu format let alone the 32eu that hx cpus come in but i knew that going in. Im leaning on the side of wanting to keep it, been running it 77w/92w/5s with no issues, better than any ryzen laptop but not by too much, if your deaf. Much better single core 1900 on geekbench5 and 11k multi no ecores. This cooler cannot handle 70w+ to save its life. Its likely dell saw the 55w tdp and said bet. If i keep it i gotta figure out how to lock my power settings in efi so i can start virtualization again.

Ill be asking someone in sales or engineering how they thought they could get away without atleast a vapor chamber.
