Pa inat je storio ovaj forum. Pa onda bolje da stavim SATA 3 žice za signal u INAT. KAd može da protera 6.0Gb/s što ne bi i zvuk

vala baš...

i neotech i VDH su monokristalni... nema tu čujne razlike na ovako malu razdaljinu. na 2cm na 10 cm ovi imaju pure silver licnasti 8500 dinara metar... još kad bi čuo razliku

naručio termo bužire kod njih i lik me pita da li sam siguran da hoću pouzećem. pa jbt da nisam siguran ne bi onlajn naručivao. mrzi ih da šalju kurirskom...

čime se to lemi jbt

sad več idemo u teorije zavere da nakalajisana žica lošije svira nego ona koja nije. 31 lem na putu signala ne može bolje da svira od onog na 10 lemu....izbaciš ceo analogni deo i to je to

aha , kalaj ima veći otpor

Inače imam još jedan D10 .... u rezervi... Najbolje svira kad se direkt žice zaleme direkt na relej odnosno najbolje je da se preskoči cewo relej i ulemi na LPF

UTP 6 kabl ide na USB priključak...ali za audio signal ide VDH...i to licnasti

ova žica što imam sad je 0.0003 oma na 10 cm dovoljno

svašta sam probao. u jednom trenutku puca i žica i izolacija.... najbolji rezultat dobijem kad ogulim VDH i ubacim u termobužir.... a onda zalijem farbom

Na kraju ću da uzmem pure silver žicu juvelirsku i sam da stavljam izolaciju

Ma bre niko nema uvrnute žice bušilicom u preampu, DAC Ali je realno da se bolje uvrću licnaste.

Naručio VDH SCS-18 za ožičenje - kad je bal nek je maskenbal....

ne znam da postoji drugi način preko Arte

Kaže Leo da je još uvek u šumi

Nema Topping... Ne postoji više. Menja oblik

U suštini BOžija volja što sam ubacio linearni sa BUZ10 .... tako treba da bude

super. ja ću to dočekati negde 202X godine

Pa sve idu kroz Intel Me.... Kad skineš skroz nema ništa. Radi kao Komodor 64 Nema Intel Me nema ni rupa ni zakrpa... 4 megabajta mi manji BIOS.... odnosno free space

evo kako se uklanja Motive Some bright minds have found a way to neutralize Intel’s backdoor5 i.e. not completely kill it, but make it harmless. Now neutralizing just your MEs isn’t going to stop your other machines from prying. Security experts and the paranoids will rightfully suggest Knowing it’s beyond me, why am I still doing it? Well definitely not for security6, but the hacker in me would like to own his toys – a reasonable expectation. A stranger shouldn’t tell you how to use your pen; even worse, use it behind your back routinely. It’s as simple as that. It’s probably one of the reasons7 I’m a FOSS loyalist. If this makes sense then you should clean your machine too, but at your own risk. Make sure you read the ME Cleaner guides, check versions and compatibilities then proceed cautiously. Basically, we’re going to do a BIOS firmware update8. Just that it’s not done internally using software but externally with a cheap BIOS programmer. How come re-programming the BIOS firmware shuts the backdoor? When you cold boot your processor, it starts with an amnesia and so it always starts with the BIOS boot program. In this program, there’s a hidden kill-switch for the back door: the HAP/AltMeDisable bit. If set, ME will just boot the host and halt. Let’s get on with it! Connect You should just be able to physically access your motherboard; no soldering involved. Tools USB Programmer CH341A (left), SOP8 clip (bottom), SOP16/8-DIP8 board (top) CH341A (Black) is a cheap9 USB SPI chip programmer. The SOP8 clip – that saves you from removing and re-soldering the BIOS chip – is sold separately. Make sure you buy the clip that comes with a SOP16/8-DIP8 board; this proxies as the BIOS chip going into the programmer’s slot. Take note The first bit is denoted on the BIOS chip-top with a circle marking. Make sure the clip’s red line, denoting the first bit, matches with this circle i.e. first on chip is connect to the first on clip when clipping. Connect the wire end of the clip to the board such that the first bits match – the board has all bit pins marked. Usually a 10-bit bus cable is used as the connector; notice that bits 9 and 10 are cut out. Look at the CH341A programmer board for a drawing about the 25 SPI BIOS chip layout. This should also have the circle marking. Connect the board-end of the clip such that its first and the SPI’s first bits match. My Setup Connect the programmer’s USB to a Linux machine; I used a Xubuntu bootable USB to convert my old Windows 10 laptop. You’re all set hardware-wise. Run lsusb on the terminal and make sure you see something like BUS 008 Device 012: ID 1a86:5512 QinHeng Electronics CH341 in EPP/MEM/I2C mode, EPP/I2C adapter This means your Linux machine successfully detects the programmer. Backup Install flashrom; your distro’s package repository will definitely have this nifty tool. Make sure the chip is recognized by it: $ sudo flashrom --programmer ch341a_spi -r BIOS_org.bin flashrom v0.9.9-r1954 on Linux 4.15.0-20-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop... OK. Found GigaDevice flash chip "GD25Q64(B)" (8192 kB, SPI) on ch341a_spi. Reading flash... done. It should be able to auto-detect the chip and give you a full dump of the chip contents. If it says no devices were found, re-connect the clip; loose-contacts are common with these clips. Get two dumps and binary-compare them to make sure the connection was fine and the images are valid. If there’re multiple SPI chips on your motherboard, make sure you get the right one i.e. the BIOS image you get from your OEM should have around the same size as the dump you just made. Eeny, meeny, miny, moe 1 MiB Winbond EEPROM chip (left-bottom) was a red herring. 8 MiB GigaDevice GD25Q64(B) BIOS chip (centre) was the one. Run me_cleaner on the dump to verify it: $ ./me_cleaner.py -c BIOS_org.bin You should get a valid output. You might also check it with the ifdtool from the coreboot repo: ifdtool -d BIOS_org.bin. Clean Run me_cleaner with the soft-clean option. It’s the safest; others wipe out the Intel ME module regions from the firmware; this one simply sets the bit. $ ./me_cleaner.py -s -O BIOS_clean.bin BIOS_org.bin Full image detected The ME/TXE region goes from 0x1000 to 0x200000 Found FPT header at 0x1010 Found 11 partition(s) Found FTPR header: FTPR partition spans from 0x1000 to 0xa8000 Found FTPR manifest at 0x1448 ME/TXE firmware version 11.6.10.1196 Public key match: Intel ME, firmware versions 11.x.x.x The HAP bit is NOT SET Setting the HAP bit in PCHSTRP0 to disable Intel ME... Checking the FTPR RSA signature... VALID Done! Good luck! It should set the AltMeDisable (or HAP) bit and wish you luck! Flash Flash the cleaned image back on to the SPI chip $ sudo flashrom --programmer ch341a_spi -w BIOS_clean.bin flashrom v0.9.9-r1954 on Linux 4.15.0-20-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop... OK. Found GigaDevice flash chip "GD25Q64(B)" (8192 kB, SPI) on ch341a_spi. Reading old flash chip contents... done. Erasing and writing flash chip... Erase/write done. Verifying flash... VERIFIED. It will first take a back-up for disaster-recovery. It’ll also see if it could optimize by not writing portions that don’t differ. Then it’ll write and verify if the image and the chip contents match! Quite a thorough piece of software; nice Verify Now for the moment of truth! Disconnet the clip, restart your machine. The machine should boot in to the OS normally. That isn’t all: make sure you use it for more than 40 mins and if nothing goes wrong, yay! You’ve successfully neutralized the backdoor! ? On *nix, /dev/mei0 would no longer exist. Also the MEI entry should no longer show up for lspci. A more through way is intelmetool -s.
