SOIC8 SOP8 Test Clip For EEPROM 93CXX / 25CXX / 24CXX + CH341A 24 25 Series for EEPROM Flash BIOS USB +1.8V Adapter + Soic8 Adapter Programmer Module Kit (1 sets)

This CH341A programmer is the Pro version and it works perfectly fine.With the CH341A we have two editions, there's a normal version which is larger and the black "Pro" version (it's this one). It gets called the "CH341A Pro".Things to know:1) It's said online that it's fine to use as-is as long as you program standard BIOS chips, but if you start programming different kinds of EEPROM then beware of what we call the "3.3V voltage problem".Basically it only feeds 3.3V at most without unofficial modification, but with an easy fix found online (named "CH341A 3.3V volt mod" you can workaround the problem and restore full 5V voltage).2) Beware to treat the lever slot very gently because it's said online that it wears out very fast.If you don't need to disconnect your SOIC8 PCB from the 25XX/24XX slot, then just leave it as-is without removing them to save it from additional wear.When it wears out, that means the lever no longer holds the PCB pins inside strongly enough.I used this programmer to read then write back my own laptop BIOS and it worked perfectly fine, I used the AsProgrammer software to do it.

From the Hardware perspective, this is a great value product. I used it on two BIOS chips with the alligator clip and it worked flawlessly. In terms of getting the Software, that was a scary journey. I ended up using the NeoProgrammer V2.2.0.10 which I downloaded from mediafire com via dwdvb com. Since I do not trust any of these sites or executables, I installed the Software on my sacrificial PC on an isolated network. Be sure to configure your Software correctly, as it makes a huge difference in the success rate (NeoProgrammer's defaults did not work for me).

My Asrock motherboard was bricked due to power failure when updating bios. The connector was very finicky so took many tries to get a good connection (be patient). Once you have a connection it worked great and I'm back in business. I'd recommend using NeoProgrammer vs. AsProgrammer.

I seldom leave feedback - in fact this is only my third time in fifteen years as an Amazon user. I only do so when I think the product warrants it, as in this case. The ACEIRMC SOIC8 Eprom programmer worked perfectly for me. I see from the reviews that some buyers could not get it to work and left negative feedback as a result. Speaking from my own experience, it may have been that those reviewers had the wrong BIOS binary from the manufacturer. At first I had the same problem. I could not get the file downloaded from SuperMicro to work, no matter what I tried. Luckily for me, what I DID have available was a new, pre-programmed chip I had purchased as a fail-safe. However, desoldering the old from the board and replacing it with the new was not something I looked forward to doing, though would tried as a last resort. Fortunately, I did not have to. Since the programmer is also a reader, I simply copied the file from the new chip and used it to program the original. The whole process took only a couple of minutes, and I was back in business not only with the board working again, but with the bios updated, which is what I wanted in the first place. It was a failed update that caused me to brick the mobo in the first place. Another thing I see people complaining about is difficulty getting the clip to seat on the chip properly, but I had no problem whatsoever - and it is a very small chip! So before you give up on it, make sure you have a good binary file to work with. Even though I ended up buying a chip I didn't have to install (thank goodness) the small cost of $25 from eBay was well worth it for the time saved and final results.

Saved my motherboard from having to buy another one due to a bad bios flash. Couldn't be more thankful.

The SOP8/SOIC8 test clip was awful. It worked a couple of times, then the clip kept popping off of the IC. I ended up buying a Pomona test clip. It hasn't failed yet after 60 or more uses. The actual CH341A programmer and associated components work great. My only complaint is the poor quality test clip.

Absolutely brilliant and contained everything to help me recover my mini PC from a bad flash. Great value!

Needed to dump the BIOS on an HP laptop that came in a bulk auction from a local school. They didn't remove the password protection on any of them. All the previous methods from years past were useless and in the end I figured out I needed to either desolder 20+ chips and swap them with new ones or do the rewriting directly on the board. By the end the teeth on the clamp were so worn I didn't think I'd be able to finish but it got the job done. Other than that, no complaints and the price is dirt cheap for the amount of time it saved me.
