🔧 Intel Core i7-640M Laptop CPU (PGA988)
I was building a retro gaming laptop and needed a cheap upgrade for a dated HP ProBook. The i7-640M caught my attention because it’s a dual-core chip with hyper-threading, still decent for lightweight use and media. Plus, it was dirt cheap compared to any used CPU I could find on eBay.
Delivery took about two and a half weeks, well-packed in anti-static foam and a hard shell case — a pleasant surprise from a no-brand AliExpress seller. Installation was simple, and the CPU booted up without any issue. BIOS recognized it right away.
Pros:
-
Extremely affordable for a name-brand Intel chip
-
Fully functional and stress-tested
-
Great value for old laptops or experiments
Cons:
-
A bit warm under load (not unexpected for a 35W CPU)
-
Not ideal for modern multitasking
Compared to US prices (around $25+ on eBay with uncertain working status), this was under $15 including shipping. Totally worth it. It met and even exceeded my expectations for the price.
US $19.79

💻 i7-4870HQ / 4980HQ / 4770R BGA Chips Lot (PGA947 Tested)
I ordered these BGA chips as spares for repairing some all-in-ones and Apple boards. I mainly needed the i7-4980HQ, and the others were a bonus. The listing was very clear on chip models and conditions, which is rare.
They arrived in 18 days, all individually packed in antistatic sleeves with proper ball soldering — ready for rework stations. I haven’t soldered all of them yet, but two were tested and passed POST successfully.
Pros:
-
100% accurate batch description
-
All chips had clean solder balls and passed initial testing
-
Great for refurbishing old boards
Cons:
-
No thermal paste or additional accessories included
-
Requires professional BGA soldering (not for beginners)
In the US, similar chips go for $40–60+ depending on the batch. I paid under $18 per chip here. Performance is fantastic if you’re a tech-savvy rebuilder.
US $55.46

🖥 Fanless Mini PC i7-8550U, Dual LAN, RS232/485, HDMI, VESA
This mini PC with i7-8550U, dual 2.5G LAN ports, and COM support seemed perfect as a headless home server and router backup. I was skeptical because the specs seemed too good to be true for the ~$140 price tag.
Well, I was blown away. Arrived in 16 days, well-packed. Fully silent — no fans at all. It runs Proxmox and a few Docker containers without breaking a sweat. Metal casing is sturdy and surprisingly premium.
Pros:
-
Truly silent and efficient
-
Multiple COM and LAN ports (great for networking)
-
Pre-installed Win10 Pro was activated
Cons:
-
Thermal paste wasn’t perfectly applied — I had to redo it
-
No Wi-Fi module included
In the US, similar fanless PCs with i5s cost $200+. This one exceeded expectations — a rare case of “too good to be true” actually being true.

🔄 Intel i7-4930MX / 4940MX Extreme Edition Notebook CPU
I picked this up to upgrade an Alienware 17 R1 and finally unlock its true potential. The i7-4930MX is a beast — quad-core, 8-thread with unlocked multiplier. Price was insanely low (~$60), considering how rare MX series chips are.
Shipping was relatively fast (13 days). The chip was clean, pre-tested, and worked instantly. I stress-tested with Cinebench and saw a clear performance boost from the previous 4700MQ.
Pros:
-
Unlocked CPU for serious tuning
-
Solid thermal performance (with proper paste and heatsink)
-
Great for older gaming laptops
Cons:
-
Power-hungry — make sure your VRMs are solid
-
Requires BIOS support
This exact chip sells for $100+ used in the States. So yeah, total steal. If you’re into laptop upgrades, this is gold.
