L7i G7 12800HX 3070Ti
5200 MT/s CL38

This time with a modified shunt resist (5 mOhm -> 3.75 mOhm by soldering 15 mOhm on top).
Full load voltage only increased from 0.8 to 0.925V though. Was that due to the VRM amperage ceiling? Not sure.
Modified the copper pies as such that now the VRMs have 2 layers of copper pipes leading directly to the fan heatsink + putty connection to the backplate as an extra heatsink cringe .
The backplate does get hot af but that's fine, extra cooling surface.

Overall impressive results, #1 for all 3070Ti's and around 15th for even the i9/3080Ti leaderboard, so there you go. peped

#

Damn impressive

tawny glacier Feb 8, 2023, 9:29 AM

#

The modified cooling on the VRMs as shown in yellow

#

Wont win a beauty prize but hey cringe

#

The backplate at least fits

tawny glacier The modified cooling on the VRMs as shown in yellow

Are you able to tweak your ram?
From reading tRFC is really impacted by ram heat, extending to have the ram cover also cooled a bit might give you better trfc values, and improve cpu score some more for ts

This is the shunt resist Mini

Back of the mobo

willow lintel Feb 8, 2023, 9:32 AM

#

You did the soldering yourself?

tawny glacier Feb 8, 2023, 9:32 AM

#

The RAM casing is also connected to heatpipes peped

#

I went to a laptop repair shop

#

He did it quite gracefully

#

Did a quick measure of the resistance post soldering also.. Seemed OK

willow lintel Feb 8, 2023, 9:33 AM

Damn, triggering

tawny glacier Feb 8, 2023, 9:33 AM

#

He was done in 15 min

willow lintel Feb 8, 2023, 9:33 AM

But 3.5 years full on-site warranty and ADP

tawny glacier Feb 8, 2023, 9:34 AM

So do i peped

Hehehe

willow lintel Feb 8, 2023, 9:34 AM

Not anymore for you risitasnervous

Yea not till they find out what i did to it no

willow lintel Feb 8, 2023, 9:34 AM

#

Did you do the runs yesterday evening, wr had cold weather

tawny glacier Feb 8, 2023, 9:34 AM

#

Indeed .. thanks for reminding. Cold ambients really do help

#

The GPU can be OC'd more if it stays below 40C

willow lintel Feb 8, 2023, 9:35 AM

#

tawny glacier Indeed .. thanks for reminding. Cold ambients really do help

To me they dont

#

Is your brother gonna do shunt too now?

tawny glacier Feb 8, 2023, 9:35 AM

#

At some point though high OC may hurt scores because of temps

#

He is too hesitant

#

If he were to do it, we can expect 15k overall from a 3070Ti

#

peped

willow lintel Feb 8, 2023, 9:37 AM

#

You ordered those pads too that mits sent befor between the ram/cover?

tawny glacier Feb 8, 2023, 9:37 AM

#

U wanna try it Mini?

willow lintel Feb 8, 2023, 9:37 AM

tawny glacier Feb 8, 2023, 9:38 AM

#

How much would it sell for u think

willow lintel Feb 8, 2023, 9:39 AM

#

I dont know, people will probably offer less then i want for it pogunice

#

Looking at current marktplaats listings

tawny glacier Feb 8, 2023, 9:40 AM

#

Theres low demand on laptops unfortunately

#

Not sure if i can sell my boy either peped especially now

willow lintel Feb 8, 2023, 9:42 AM

#

You seem that pad that mits posted?

#

I have that on the way, when it arrives ill see if my trfc can go lower or not

tawny glacier Feb 8, 2023, 9:43 AM

#

Upsiren?

willow lintel Feb 8, 2023, 9:43 AM

#

Yes

tawny glacier Feb 8, 2023, 9:43 AM

#

Should work imo if connected to the backplate also

willow lintel Feb 8, 2023, 9:43 AM

#

21wmk advertised

tawny glacier Feb 8, 2023, 9:43 AM

#

Or better still, sandwich a copper shim in between peped

willow lintel Feb 8, 2023, 9:44 AM

#

Yes, will do some between ram/ramcover and then ramcover/backplate

#

Hope itll arrive in time though as temps seem to be going up again.
Not sure if i can do reall cold runs

tawny glacier Feb 8, 2023, 9:45 AM

#

Tonights another opportunity

#

Just ambients alone should be enuf to cool them

#

Srs

He didnt take any fees destare

woeful grove Feb 8, 2023, 5:08 PM

he disassembled and reassembled the whole mobo for no cherge(

…

#

Charge

tawny glacier Feb 8, 2023, 5:18 PM

#

woeful grove What instructions did you give him?

Simply to add another resist (15 mOhm) on PR2003 in parallel. He disassembled the modded heatsink lel and took out the mobo

#

Turned it around and simply soldered it

#

Then we did a quick test and was OK

woeful grove Feb 8, 2023, 5:18 PM

#

damn lucky

#

what’s the gains from it

#

How many points?

tawny glacier Feb 8, 2023, 5:19 PM

He was fast. Experienced also. He sent me scrap heatpipes for my copper mod

tawny glacier Feb 8, 2023, 5:19 PM

#

No that's the overall score

#

The GPU was a bit lower than this

#

The CPU for some reason went on steroids

#

cringe

woeful grove Feb 8, 2023, 5:20 PM

#

Ahhhh

#

What core OC now

#

340 before

#

370 now?

#

Or 400

tawny glacier Feb 8, 2023, 5:23 PM

#

343 @800 mV before. Now its stable 250 @925 mV. If temps < 40c, then can be pushed to 290 @925mV

#

Havent tried 300 though

#

If ambients allow, it could be possibru

tawny glacier Feb 8, 2023, 5:25 PM

Shouldnt cost more than 30-40 bucc if he wants to charge

willow lintel Feb 8, 2023, 5:34 PM

Must have been something he had never seen before i assume

#

Yes

willow lintel Feb 8, 2023, 5:36 PM

He didnt LM yours right away while at it?

tawny glacier Feb 8, 2023, 5:36 PM
