ok ... finaly i got my v4 also.
Smartphone > Dumbuser = me
)
i took some pictures during the lapping and gap removal , hit upload to google drive and immediately delete them from my phone .... thus only one pic got to drive
)
ok, so lets take it from the begining.
Another 25Eur in taxes as i presumed .... they sent it via the cheapest way possible (aka national Post). even though they charge shipping (ok, fine topton has it already baked in the price) is not the best, via Liege that is the busiest hub in EU.
with this ammount extra ... the price is the same as for topton....with worse shipping
They claim that this VAT is because i was unlucky and a spot check was performed by the customs agents. ..... to quote : we shipped hundreds of units, only 3 had this issues with the VAT.
To be fair they do not claim on the page that is fast/free shiping and without taxes like Topton does (and delivers)
Second: before i hit buy i had a discussion with the seller asking him not to sent the PSU cause i got the meanwell and to send me a FAN.
He showed me a pic and told me that is ok and it will ship it like that ... and an extra 11$ discount cupon for me.
One month later the packet arrived with a PSU and no FAN
))
Now the unit itself.
CPU soaked in TIM almost full cpu cover(not die ..cpu ) ... but it was fresher than the one i had on Topton.
Some weird spacers on the CPU ??? THE ONLY PIC
))) Probably to keep the TIM in
)
Removed those and the NIC heatsink to check for the gap
Yes is still has a gap .... is smaller the what it was on the v3 ....but is still there...... goddamn dumbuser > smarphone situation
So i filled it down to "spec" and also removed the first anodized layer between the cooper and case. ... I read somewhere that anodized Al can be made in 2 ways ... one has no influence on thermal conductivity, the other method does ...in a significant way.
So better safe then sorry i removed the fist layer and lapped the surface.
Then i lapped the copper block ....which had some big grovves in it from the machining.
And quess what ... the cpu side was concave ...the case side convex ....nice....NOT (those are the pics im most mad abbout loosing)
Anyway ... fixed the gap, lapped the copper and the case, put new paste properly and power it on.
Bios is different .... ill need to get around to take a look in more detail...but i saw there are some new PL levels by default 15 -25 instead of 15 -30 on the old one
Bios version JK4L v103
Bios date 07/30/2022
So now is running a Prime95 session fro about 6 hours now.
Nothing changed in the bios is running 2.3 - 2.4GHZ all cores at about 60-65 C which is not bad at all in a 23C ambient room.
Never one hit thermal limit
Still looking for undervolting this ... i think it would be good performer with -50mv on the cpu
LE: If anyone knows how to recover pics deleted from the phone ... let me know
