However, you DID say that you where not going to de-lid the processor. BUT if you do de-lid, you'll drop more than 1 or 2c in most cases while the stock TIM under the IHS plate doesn't do well. Hence this thread
Yeah I knew that, with my i7-5775C I dropped probably about 20C or so from 4.4GHz using my Corsair h100i. Though I really would consider going bare die on this QX9650 if there was a fool-proof way of delidding a soldered chip. I mean I have seen one of der8aur's videos where I think he delidded a 6950X and It dropped a few degrees off like 5C-6C. Idk just kinda of a weird project to do, mainly because 775 CPU's are cheap if you screw something up . Its mainly difficult because of the 2 dual core dies under the IHS so theres more solder holding it in place than say a 6950X or similar CPU, or at least that's what I think. The only soldered CPU I delidded was an old P4 and I know I killed that but I was also not really trying not to lol.

I only know one guy thats delidded enough processors to help a guy like you with a solder chip. Me.
My last soldered delid was tge 2700x. Ive done multiple Phenom and FX chips successfully. 16 in total if memory serves well today.
I have a ryzen 1200? 1300? On the way, thats getting a delid. Have a 1400 that needs it too.... Doesn't need it, I just like delidding.

But when delid a soldered chip, its best to run without IHS plate on a custom loop.

Yeah that's the plan in the future possibly, I used to have an old 3770K that I ran bare die at like.... 5.4GHz or 5.6GHz if my memory serves me (for benching) but those are cake to delid vs having to heat up the IHS and such to get solder off, which I am pretty sure you know since you have probably done a fair amount more of them than me . But for the most part have semi-retired from that because it got expensive killing top of the line mainstream socket (at the time) hardware for a few months until i'd have to get a new one. It'd just be fun to actually delid this thing in all honesty, without killing it of course lol.

A rule of thumb I use for de-lidding. Never heat the IHS plate for more than 60 seconds. if the solder isn't melted within 60 seconds, you will kill the processor. With a Med to High flame with my Power Probe solder torch that's about the time it takes. usually 40-50 seconds. If the room is quiet enough, you'll actually "hear" the solder let go.
The nice thing about AMD IHS plates is that they are large and rather tall. I use a heat sink on the pins. Hold the PCB with a model vice and clamp a pair of vice grips onto the plate. I only use just enough force with the vice so that the cpu stays pins down onto the heatsink with the weight of the vice grips attatched hands free. Once the solder melts, I just pull straight up and the plate comes right off. With AMD chips a heat sink under the pins is a must. i won't tell how I learned that the hard way 'whistles"
But yea, that's pretty much my secret above. pretty much exactly how I remove soldered IHS plates. Super easy and super quick. If I didn't need to cut the glue, it would literally take me 1 minute per de-lid. but throw in cutting glue, removing solder and lapping the core a bit.... more like 1 hours or more. haha.

I was getting error code 23 on my aorus master pro and the computer would just boot cycle it wouldnt stay on. I'm thinking a short somewhere? I tried putting back on the original socket tensioner and ihs just to see if it was the mounting pressure that was not enough from the direct die but I get the same error code too. The error code is not listed in the gigabyte manual or anywhere online. I tried only one stick of ram in the 1st and 2nd ram slot but I haven't tried the 3rd or 4th yet because I ran out of time but I will try that later today. Has anyone else had this happen before? The cpu doesn't seem like its dead because otherwise the motherboard would show the error code for the cpu and it would just stay on and not boot cycle. Also I couldn't figure out how to get all of the black silicone off of the die? I used a plastic credit card to scrape most of it off, could that be an issue too?
I haven't seen you post back here for 2 months. What was the resolution of the issue? Was the CPU gone?
And removing the leftover solder is easily done with the quicksilver kit that rockitcool sells. But you have to leave it on awhile and also work it in and scrub it with a Q tip. I delidded my 9900K with the rockit 89 kit and got all of the quicksilver off, but it took awhile, and was slow. Then you can use their fitz(?) metal polisher to get it nice and shiny. If you wind up with some super hardened mark or something that simply won't come off, you can try 3000 grit sandpaper, but be very careful and wary of damaging the backside. If there are any scratches on the die, however, you may have to actually truly sand it with the way der8auer mentioned in his video.

What was harder than cleaning the solder was cleaning the Intel RTV or whatever they used black glue off the PCB. Now THAT was scary, even using a credit card that took an amazingly long time and required being careful not to damage the PCB or break something off the back.

If you didn't damage any motherboard pins, then the only thing I can think of is that you static shocked something or damaged a SMD or something on the backside. Since you were using the direct die frame and I've seen people have problems with POST failures and that frame, I would see if you can test it in another motherboard and re-lidded with LM.

(I am sure I might have posted here 4-5 years ago, when I attempted to delid my 4770k. I had a knife slip scare and stopped my delid attempt, and thought I destroyed the CPU, but I was lucky that I didn't cause any damage and that the CPU worked flawlessly)

Anyway, today, after so many years I tried it again out of boredom. I must have seen 9000 videos of people delidding with razors, and even a vid with someone delidding with the plastic package from his CPU, and another guy using a small plastic card. The idea was that you only need a tiny 2mm cut in one edge, and then use the card and do the rest. Sounds totally trivial, right?

Anyway, to make a long story short: I really tried today with a small exacto knife just to cut a small 2mm slit in the side. NO DICE. I tried several times and took my time, doing exactly what I must have seen a million times in videos. The black silicone is just so rock hard I wasn't able to even get into it, whatsoever. So I aborted that attempt too. I figure there is no other way than using a tool, fortunately you can now get these mini vice delid tools from China for €5 where people had success with. If I am bored again I might just get one of those, but not sure whether I care with such an old CPU. I was sooo convinced I get it right today...grrrrr....

Bios modding and flashing until the EEPROM smokes!! Yay!!
