So im gonna try my luck on an intel ES chip with a chipped OFF corner
planning to buy this Q0L4 13900 ES2 cpu the seller has chipped top left corner completely instead of the usual drill mod that we see in china ffs i cant find any proper lga1700 pin out diagram to know what those pins do, the translation in the listing says “The missing part is the core power supply redundancy module” so i must assume its VCCCORE DC mod
pins that are chipped off i marked them as green
The usual drill mod
you can see a drilled hole on top left i am used to seeing this mods in higher end ES chips, people usually do these to regulate voltage so the ES doesnt end up frying itself. i dont know the actual reason as there’s very little known about these mods outside chinese forums. Posting this here to gain some insight before pulling the trigger
So what i know about these ES chips
- 12th gen ES has a lot of bugs and the primary pcie x16 slot on the motherboard doesnt work with them so u end up plugging gpu in secondary slot resulting in lower bandwidth due to fewer lanes
- 12th gen ES have a lot of bugs and very often blue screens and memory runs in single channel
- for 13th gen ES there are no major bugs like 12th gen like the pcie not working and blue screens but some ES chips that are intended to have iGPU doesnt always work and the seller always mentions if iGPU works or not in that particular chip
- Some 13th gen cpus might run with fewer cores like i saw a 13700 ES Q0L5 it ran like 4P cores and 8E cores rather than 8P cores and 8E cores
- There are several revisions of ES chips they refer to them as ES1 and ES2 I was going tu buy a Q0D8 thats 13900 ES1 but thats out of stock now everywhere so left with no options than to buy chipped of 13900 ES2 Q0L4
- also ES1 always performs way worse than ES2, QS(Qualification Sample), Retail, there’s like 3k point difference in 13900 ES1 multithread cpu-z and 13900 ES2. 13900 ES1 only scores 11k while 13900 ES2 scores 14.5k
Before this i have tried using an AMD ES cpu that is 7600x’s ES version AMD es chips perform almost same as retail with no bugs they are basically QS not ES only the caveats being lower boost clocks and 3-5% worse performance
