Hi, as I wrote default settings do not work, also tried several changes in BIOS memory settings, but to no avail. It's also quite difficult to test, as the board does not go into BIOS on Patriot mems, so need to change mems to different make, alter BIOS settings, and then change mems again to Patriots, and finally test. So Gigabyte messed up something in the BIOS, as these Patriot mems are very good mems based on Samsung B-Die chips, and they work in all other motherboards makes I repaired, and these are several hundred by now.
Also my experience with Gigabyte mobo repair is the worst...

ASUS PRIME TRX40-PRO S - component identification
Hi Folks
I have an [B]ASUS PRIME TRX40-PRO S[/B] motherboard with an ripped off smd element, looks like a SOT23-6 case (like a dual 2N7002 mosfet).
Would appreciate a picture with component present or the component marking. Unfortunately no BV/Schematics available anywhere.
Thanks in advance.

By now I'm almost sure that this is a partially faulty chipset. I have already a replacement one, will report what will be the effect after replacement. I know about the SATA sharing issue, but this is most probably not the reason, as I tried all possible configurations with M.2 port, but there is completely no difference.Leave a comment:

GIGABYTE GA-H110M-S2 - Stuck at Debug Code C2 - don't like Patriot Viper Steel RAM but works with G.SKILL
[FONT=Tahoma][SIZE=14px][B]Hi,[/B]
I discovered a strange behaviour of GIGABYTE GA-H110M-S2 board.
General test conditions:
- Tested with Core i5 6500 and Core I7 6700K - no difference
- Default BIOS settings, but tried also altering several memory setting - does not change anything
[B]What is wrong:[/B]
With BIOS F1 and F2 the board normally POST's and boots to Windows 11 with 2 x Patriot Viper Steel PVS416G440C9K RAM (4400MHZ, Samsung B-Die chips)
When BIOS upgraded to anything above F2 (ie. F20-F27b) the board POST...Last edited by DynaxSC; 03-21-2025, 07:48 PM. -
GIGABYTE X299 AORUS ULTRA GAMING - SATA PORTS 4-7 NOT WORKING ???
Hi,
I have the above mentioned bord after repair, which was related to a lot of missing smd devices on the back of the board.
There were almost 20 devices missing, caps, resistors and some diodes/mosfets.
The board is generally working now, all PCIe ports are working, Windows installs normally.
However I have a problem with SATA ports 4-7 (the board has 8 SATA ports) - disks are not beeing recognized by the BIOS neither by Windows (which is usually normal in case BIOS does not recognize them).
The SATA 4-7 driver network is quite simple chipset<->buffers/drivers<->SATA...Last edited by DynaxSC; 03-10-2025, 02:24 PM. -
Have you looked at the boardview's I posted, maybe they can be of help for you. Does the vrm controller gets EN signal?Leave a comment:

On ASUS boards usually its enough to program the first stock BIOS version to enable the ME, there is no need to do such a comprehensive ME cleaning procedure. Then only thing left is to write the corresponding DMI data back into the image (must naturally do first a backup on the original BIOS).Leave a comment:

[B]Hi, I can't believe this, I have solved the issue, having almost given up.[/B]
[B]Everything I had to do is change the disk in Samsung Magician to work in FULL POWER MODE. This is an option in Performance Optimisation.[/B]
After changing this, the disk boots with Windows without any issue also in M.2_2.
Seems this board is just not able to correctly handle modern disks with power saving functions. This is probably really a BIOS or Microsoft NVME driver bug, or an unsolved Samsung Firmware issue, who knows.
For all those people struggling out...Last edited by DynaxSC; 02-23-2025, 06:59 PM.Leave a comment:

ASUS ROG STRIX B550-I GAMING - M.2_2 port not working correctly with SAMSUNG SSD980 1TB NVME SSD
Hi,
I have an really very weired issue with ASUS ROG STRIX B550-I GAMING.
Some NVME (PCIe) SSD's are not working correctly in the second M.2 socket. An example of it is the SAMSUNG SSD980 1TB NVME SSD.
Some other NVME (I have only smaller ones) disk do work without any problem, also SAMSUNG disks, eg an MZVPV128HDGM-0000.
The behaviour is also really very strange, i.e.:[LIST][*]The disk shows always up in BIOS - so it is recognized, so far so good[*]POST-ing with this disk with fresh Windows 24H2 installation (done in the M.2_1 socket) in the M.2_2... -

To measure VCORE resistance on a GPU u need a milliohm meter. It has a slightly different design compared to a standard DMM and uses 4 wires from meter to probes (2+2). So it is able to compensate the wire resistance when measuring very low resistances. I'm not sure what should be the resistance for a RX6900XT, but for a healthy GTX1070 it is in the range of 150-200 mohm. You can buy some milliohm meters on AE, and they are affordable and do the job. Anybody dealing with GPU repair I'd recommend to have one, as it helps to check GPU very easy and fast.
If you have a high quality DMM...Last edited by DynaxSC; 02-21-2025, 11:26 PM.Leave a comment:

If the SPI chip wouldn't communicate with PCH, the board would not even start to POST. If there is no ME version or it is 0.0.0.0 the bios image has been probably messed up, probably overwritten a stock bios image and made no backup of the original BIOS. PCH must be somewhat "paired" with a new ME, now this "pairing" is lost. You must now initialize the ME on the PCH. There are some posts on this forum how to do this, look for them.Last edited by DynaxSC; 02-21-2025, 10:58 PM.Leave a comment:

Reflow of gpu and all mems is like shooting with a tank to kill a fly. Use Mats first, like ktmmotocross recommended, and reball only one these mems which are faulty. Reflow/reballing of gpu is the last thing to do, it is risky as there is always a big stress to the chip. To my experience reflow or even reballing does not give always permanent results. Sometimes chips repair their silicon due to heat, but then get back degraded after some time. It is difficult to determine if the reason was bad contact of balls to pads or internal issue on the silicon. You do right here to test the card for a...Leave a comment:

Screens look good, the ringing is normal. Pls be more specific, "quite warm" is not a very exact information. Measure the temperatures, test the vrm under full load. This is also a quite old construction, so vrm efficiency (thermal losses) might be not as good as today. The heat might come also from the coils resistance. Have you checked if the replacement mosftes have lower Rdson (this is crucial for thermal lossess) ?
Regarding the Panasonic caps you should consult Panasonic design guide (available on registration), the FK datasheet itself is crap, has completely no information...Leave a comment:

Just measured a few low ohm resistors and shunts, all OK.
Then tried a few BIOS'es for similar looking cards, including the one for Twin Edge, and the effect is the card is gone to heaven for now.
VCORE is only 0,3V and fan 100% RPM.
No idea what happened, but seems the problem is become even more mysterious.
Measured VCORE resistance with mohm meter, and it's quite low, 0,09 oms (90 mohms) - this is in a range, where the core might be already faulty, at least if I compare to GTX1070, where the core has usually 150-190 mohms.
Might be that something stopped contacting...Last edited by DynaxSC; 02-13-2025, 12:58 PM.Leave a comment:

Tried to change the VRM controller to:
1. uP9511P -> VCORE present but card not recognized by the BIOS
2. uP9511S -> VCORE not present, card not recognized in BIOS
3. A second uP9511R -> same bahaviour, so VRM chip seems to be OK.
I wounder if it shoudn't be a uP9512R, will order one.
Would try also another BIOS, but no BIOS'es for this card available at Techpowerup.
