the cpu is at 4.7MHz because that's the highest its allowed to ramp up (all cores locked via TS at 4.7), power plan aka Ultimate Performance places cpu to its highest state until PL2 rules are broken and then cpu is placed within PL1 power limits followed by reducing MHz to reduce thermals, the graph is showing that the cpu was able to run through Time Spy bench without breaking PL2 rules which would have placed it in PL1 limits, the unit is essentially maintaining manageable PL2 terms during the bench with undervolt,

i made bit of a mess with the info i submitted earlier, here is live capture with info present live so there's no confusion, not trying to break records just to capture power usage during runs with 240w brick CB23 Run 3DMARK Time Spy Run 330w brick CB23 330w Run 3DMARK Time Spy Run 330w AIDA64 Run 330w (290w+)

i should still have a copy of Aaron's vbios, it wouldn't flash the old 7670, my current 7770 vbios is 94.03.19.00.EE

here are the graphs for my best score mentioned earlier, note cpu is holding 4.7Mhz throughout the run, this is very different from previous runs with early cpu undervolt and gpu overclock setting, with all my previous settings that purple line would dip to around 1.7MHz almost instantly (yes this is replicable), with 30w withheld from 150w = 120w which what we all able to get in effect, 25% performance missing from an already capped 175w dGpu to 150w we only get 120w from, if Dell allowed us to regain the full limited 150w i bet we could close the gap we currently see, https://www.3dmark.com/3dm/85032368

maybe its just placebo... after BIOS 1.8.0 update my system seems to idle 3-4 degrees cooler (package is usually 41c at idle),

noticed some weird hardware error issues recently, not sure if they were there the whole time or started recently, i tried to eliminate variables to try and narrow this down but i have no lead atm, it is not caused by the under or overvolting, its not a driver compatibility issues (went back to original OEM image), seems to be related to the dgpu but no additional info can be found even system logs are very vague, it wont happen during CB23 run nor when running Valley bench, but if i open Afterburner or 3DMARK just to the main interface not even running tests yet it will trigger these hardware errors instantly, can someone please help validate if this is just on my system?

the system pulls noticeably allot more power from the wall with the 330 brick, 280w is the average sustained pull form the wall during Time Spy bench, with the slim brick it pulling a max of 235w but averaged much lower 180w sustained, difference in scores is 0 during CB23 bench with 25.5k scores if i recall correctly it wont even reach PL1 limit, it utilized 81w max for the whole run, it wont thermal throttle either unless i hammer it with 4-5 consecutive runs without cooling for a minute, even fans don't ramp up through the run, i haven't tested my current config with my special sauce yet, i believe adding that will get me over the hump to the 26k score,

same here, if you get the 7770 without dgpu, connected to external enclosure via thunderbolt with 4090 gpu you should have a chunk of change left with twice the performance if you went the 3080Ti or the A5500 route in the 7770, the 3080Ti and the A5500 are both priced over $2200 option for the 7X70 line,

my best 7770 3DMARK Time Spy score so far 12145, allot of tinkering to find the right undervolt balance, what's interesting is with the right undervolt settings i am finally able to maintain 4,423 MHz average clock frequency throughout the test (with all my previous attempts i got good scores but cpu always ramped down to 2000Mhz), still getting slight thermal throttling but not enough to ramp the whole system down, 25.5k scores in CB23 are a regular occurrences now, trying to hit that illusive 26k CB23 score, (id share my tests graphs and TS settings but i am not allowed to upload anymore images ) https://www.3dmark.com/3dm/85032368 (with LM TIM application on both cpu and dgpu) TS > FIVR: CPU Core -146.5 (-150 effective) with IccMax 185.00 CPU P Cache -73.2 (-75 effective) Cache Ratio > Min/Max value 8/36 Turbo Groups > all performance cores set to 47 (everything else left to its default settings) MSI Afterburner Settings Core Clock (MHz) +225 Memory Clock(MHz) +1400

i was wrong (must have mixed it with older 7670), this one goes up to 3600 rpm,

i have used your Dell Fan Management tool, i observed well above 3600 rpm, i think it goes above 4000 rpm, but i never stress tested with the tool monitoring during stress test just when it switches to cool power plan there's a ramp up window during that i observed, i can run a quick test to see what we have here,

wow how are these fans moving any air for the system being this clogged after 4 months, interesting, there's another SunOn fan model, you seem to have a model with dense fin formation like the Delta in one of the systems i received, the Sunon in my current system has a less dense formation then yours (i noticed it immediately when i saw it), be very carful when removing the cover, the cpu and gpu are not very secure or supported in there, any movement could cause paste movement and loss of performance, i noticed over 10c increase from adding m.2 drives in and out, at first i thought it was the m.2 drives adding overhead to the cpu raising its temps by 10c,

@Jack YouTube is your friend, spend some time watching few videos on how it is done you should grasp the process pretty easy, if you scroll back you will find handful of repaste tips and pics i posted throughout this thread, good luck,

7770 stripped down P.2 the replacement unit that arrived came with Delta fans with denser fin formation (i think that's the part @Aaron44126 replaced), on the left is the first unit with Sun On fans, the one on the right is the newer replacement with Delta fans,

7770 stripped down P.1

despite the 330w brick and obvious extra power being pumped through, 3080Ti remains stuck on 120w max usage, i raised another ticket with dell pro support for this, lets hope its a simple configuration error carried over from the 7670, if they fix this issue my next issue will be finding a solution to running fans at full blast manually, the 20 year old logic still embedded in both windows and Dell's old bios power plans is just too anemic for these powerful cpu's, we need to be able to use fans on demand, especially for buffering heavy work loads in advance,

im baffled, no thermal throttling despite the high wattage pumped through, i thought it was some mistake the first time i noticed it, i guess i wasn't imagining things after all, with the 240w brick thermal throttling is almost instant (below vid is with ultimate power plan in windows and Ultra Performance in bios on),

235w was the max i saw with the 240 brick before (with the same power meter), just run AIDA64 complete stress test, during the test the unit pulled constantly thorough the whole 10min test 275w, and was not thermal throttling for some reason (need to investigate further), the 330w brick is big thick and heavy, not something id ever want to travel with,

W00T 330w brick works! saw 288w being pulled out the wall during AIDA64 full stress test,

the cpu still has a 242w power limit that has to be removed first to change its behavior, see below in preparation i have "Power Limit 4" set to 0 (0 means no power restrictions), if you haven't changed yours it should read 242, that is a hard cap on overall power, plugging a 330w brick without changing this shouldn't change native cpu behavior, that 242 in PL4 field is the instructions to ramp down before wattage consumption reaches 242w, you could set it to 330 if you feel safer with a power lock, my brick is out for delivery and should arrive shortly, my cpu reach its 157w limit every chance it gets, if i run it in bench without gpu load it will run with 157w for quite some time before it starts ramping down, i suspect native setting might be limiting your cpu, power plan will be limiting power too, you need to be on ultimate power plan in windows and in bios on Ultra Performance to get the max out of cpu and gpu during bench testing,

NVidia cheater driver settings, which at this point I suspect majority of 3Dmark scores are saturated with, my 7770 true score is 12100 so far https://www.3dmark.com/spy/33265268

my best result for the 7770 so far https://www.3dmark.com/spy/33349326

the 7770 in the link i used must have sold by now, the 7770 in general is still listed click here they been pushing lots of specials for outlet products with deeper discount then before the past two weeks,

interesting, out of curiosity i plugged in a power meter to the wall jack and the power supply to the power meter, run a 3DMark Time Spy bench, during the 2 initial tests the power usage was around 175w-180w, during the 3rd and last phase of the test that suppose to be cpu focused stress test, power usage spiked up over 235w few times, i also noted that when on cool power plan and power saver in windows the draw from the wall is still between 40w-60w at idle, out of that HWInfo reporting cpu using only 5w-6w, when the unit goes to sleep power draw from the wall jumps between 1.8w-3.6w,

the GPU cannot ramp up at the same time as the cpu, if it has a none cpu dependent chores yes, a task requiring both to run together at their peak is where issues begin, they can do it each on their own but the juggling act of running together is very tall order for 240w power supply, together they demand more peak power than is available to the system and why i ordered a 330w power supply, the cpu has a locked Power Limit 4 (PL4) value which tells the cpu to power itself down when overall consumption reaches the magic number of 242 (PL4 value should be 0 for the cpu to never ramp itself down), the cpu in its turbo cycle it will consume every bit of its 157w allotted which leaves 83w for the rest of the system including the 3080 that cannot use its full 150w power potential unless the cpu is slowed down somehow to free up power,
