M7720GA - make 7720 great again

[Annihilator]

bcs im waiting for my replacement mainboard for the M6800 i started to shop some stuff for the 7720 to make it comparable to actual notebooks(except the number of threads the CPU can work with 😄) 

Service Tag: C9GP6H2 so u can see original configuration.

 

Original Configuration --> planed - ordered - already done/delivered:

 

Intel i7-7820HQ --> Intel Xeon E3-1575M v5

2x 8GB DDR4 2400 CL17 --> 2x 16GB Kingston HyperX DDR4 2666 CL15

nVidia Quadro P3000 6GB --> nVidia Quadro P5200 16GB

1x 512GB Toshiba XG3 NVMe --> 1x 512GB Samsung 960 Pro NVMe + 1x 1TB WD SN730 NVMe

WIFI AC --> WIFI 6E

Windows 10 Pro --> Windows 11 Pro

Stock SSD Heatsinks --> 2/3mm full Copper Heatsinks

 

upgrades for later:

1080p Screen --> 4K Screen

nVidia Quadro P5200 --> RTX 5000 / 3080 / 4080

Stock Heatsink --> Cicichen RTX Heatsink

When you list DVD, you mean external right ?

Yeah, I didn't get the "DVD" thing either. He must've mixed it up with the M6800.

yep, my bad was copy n paste from the other thread n only changed the stuff, this one slipped in 😄

some benches:

original Toshiba XG3 512GB(really poor performance, even for a main/OS drive):

 

new Samsung 960 Pro 512GB:

 

and my game drive a WD SN730 1TB:

 

original 2x8GB SK Hynix 2400 CL17:

 

and new 2x 16GB Kingston HyperX 2666 C15:

 

 

so the new mem has(rounded) +10% higher read, +17% write and +21% copy bandwith and 3% less latency. 

Timespy CPU score is +6.3%, firestrike +8.2%...

 

im really excited for the new mainboard with the E3-1575M V5, should be give another blast in gaming stuff.... ordered already the custom heatsink for RTX cards from cicichen, he said need around a week to make + shipping, x-vsion wrote me back, they have a RTX A3000 12GB with 140W TDP in stock, think will go for it n stay -atm- at the 1080p screen then. 

 

and another thing i noticed n easy to optimize is the airflow, when counted right there r 1073 holes for air intake to the fans each has a diameter of 0.8mm, that means each hole has 0.503qmm = a total of 539.7qmm, will drill the holes out to 1mm each, that will increase the intake opening to 842.3qmm = +56% higher air intake and the noise should be down too bcs of less turbulences.

ok, got a 1.2mm drill n did it, temps goin down noticable, was running furmark + cpu-z stress test to generate maximum heat, left bottom cover with original sized holes(0.8mm), right with 1.2mm holes:

 

 

GPU temp is down 4°c. n CPU 5°c.  ambient was on both tests at 26°c.

Do u have any pictures of how the holes looks like?

sorry for the late response... yeah took a pic while was on it... n u really able to feel the difference when u blow on the original holes, u nearly not feel anythin on the other side with ur hand, with the 1.2mm holes u really feel it, but no wonder 1.2mm holes have a 125% bigger air passage then 0.8mm:

 

 

 

and is a f*cking boring work, doin over 1000 times the same shit 😄

new mainboard with xeon e3-1575m v5 arrived, will take a look on the VRM section maybe will upgrade the 3 phases to a 3x2 when possible.

 

next on the list is better heatsinks on the SSDs... they r getting over 60°c. at load that means already throttling(960 pro has a 2 step throttling; first is at 50°c. second at 70°c.), measured 2mm high heatsinks will fit easy with thermal pad, 3mm ones would need thermal paste bcs he thermal pad is even in the super slim version slightly too much for the 3mm one... n the heatsink will be fixed with silicone straps anyway, so maybe will use with thermal paste.

No problem. Damn... the holes looks really clean, you did a great job

That's nice. If you really do upgrade them (VRM and SSD heatsinks), please share it with us

easy to resize holes, everybody can do that... but even without pre-existing holes i could do that easily(im machinist 😄 )
