Any 8480+ works without modification?

no, only 24xx/25xx QS/prod.

Or also could you give me how did you modification them?

if i managed it myself. you need to desolder the BIOS chips, in circuit flash brick the board,
if i read the small i get data form the bigger, 4 reads give 4 different CRC checksums.

I also planning to give it 3060/3070, did that 750w PSU support?

there are two 6/8pin out of it, 12V - 36Amps. but there are 1000 and 1350W units, with luck used for $175usd

Any M.2 heatsink for that?

its included, just installe it (the screws shorten contacts)

Modding an E-ATX could be suitable to fit this case?

anything is possible. i found the Case for 1200 yuan (goofish/taobao)
T5860 / ??T7865?? / T7875 have same case.
size is: 31cm x 42.5cm (from back Audio jack to front headphone jack.

Other than this Dell mobo, it is expensive to afford these 4677 mobo. Any other recommend for this? I want something could fit around 300usd

unless you don't find a great deal, ASRock WS W790 R2.0 is cheapest W790 board with QYFS support.
don't forget you need at least 4x DDR5 RDIMM to have no big RAM bottlenecks.

 

[RolloZ170]

Do we have something noticeable or maybe locked like some epyc/threadripper.

if you have source of cheap TR sWRX8 have a look to this

Dell lock 3975wx could be installed into this?
Also, overclocking is possible?

DELL MOTHERBOARD 1G0M6 PRECISION 7960 TOWER FCLGA4677 SOCKET W790 DDR5 | eBay
So i found the 7960 motherboard which is pretty good. Could this work without modification?

 

[RolloZ170]

afaik this board runs TR PRO 5000
there are manual for 7865 at the Dell site

Also, overclocking is possible?

don't know. i doubt that.

no ES support. no QYFS.
but runs QS/prod. Xeon W 24xx/25xx/34xx/35xx
thi s mobo needs very very special PSU with power distribution unit and don't work without orig. front panel unit(EC on it)
look better for ASRock WS W790 ( is about $600usd) or ASUS W790 Ace (open box)

Didn't they share the same socket?

 

[Civiloid]

Didn't they share the same socket?

Threadripper pro have different socket compared to Xeon 34xx/35xx.

But vendors have a way to lock motherboard to accept only a subset of the CPUs even if the socket is the same

 

[RolloZ170]

Didn't they share the same socket?

Dell Prec. 5860 runs 24xx/25xx only NOT 34xx/35xx but same socket.
Xeon Ws do not run on LGA4677 chipset C741 motherboard and vice versa.
so answer yourself,
charing socket means nothing.

I mean the sWRX8 3000WX and 5000WX
I know that LGA4677 is difference from sWRX8

I mean that could we run 3000WX in sWRX8 which support 5000WX?

 

[RolloZ170]

i just want to explain that same socket not means support, BIOS must support too.

I mean that could we run 3000WX in sWRX8 which support 5000WX?

yes if the manufaturer wants that.
Dell Prec.7865 is not shipped with TR 3000 series, so i would say NO (politics)

Hi everybody.
I got dual Q2SR and ms73-hb1 rev.3
How to modify the bios to support it

 

[RolloZ170]

I got dual Q2SR and ms73-hb1 rev.3

PM you

 

[pppcx]

T5860 / T7875 / T7865 have same case.

Any supporting information? I can't find the 7865 case sold separately anywhere, only the 7875 case. But I checked the pictures of these two motherboards and find there are some screw holes that seem to be in different positions.

 

[Fedulld]

Not work with the oc memory kit,2 week later coming another 8 micron 4800mhz standard module.
I think good board but if/or you want sound card,vga,ssd not so good.
I have another one this is Asrock W790ws very good board!
8480+ es working fine,with 4200Mhz turbo.
View attachment 39004

Excuse me for bothering but I am new here even if going through almost all the gazillion pages and discussion in this and the QS motherboards discussion.

Could you please share your OC settings? Because almost everyone is making that those CPUs don't overclock yet you got it to 4.2Ghz.


Got a 8480+ QYFS and for two weeks now dithering what motherboard to buy between the W790 Sage and the MS33-AR1. Reason is one supports OC but going to get stuck with 8 RAM modules while the other has 16 RAM slots and doesn't support overclocking.

Also could you tell me please what heatsink or waterblock you are using? The temps look pretty impressive considering.

Thank you.

no sorry, found some only at goofish

But I checked the pictures of these two motherboards and find there are some screw holes that seem to be in different positions.

 

[pppcx]

no sorry, found some only at goofish

I find that there are only T7875 cases for sale on goofish, no T7865 cases.

I tried to compare the two motherboards' pics on Dell official website and found that the screw holes can't be aligned, so the chassis shouldn't be common in all probability
