THE GOOD: The chip has hyper-threading, 1 meg of L2 cache, and SSE3 instructions on chip.
THE BAD: High temperatures create serious cooling issues.
SUMMARY: If you run this chip like a normal computer user would, IE. email, web browsing, and word processing, the chip should idle somewhere around 110 F or 42C, this is with a Thermaltake Spark 7+ on the chip not the stock cooler in a 478 socket. Which is about what my previous AMD 2700+ overclocked chip to 2.8 ghz ran at.
The problem is that there was some type of manufacturing problem with the original socket 478 run of these chips and under full load, which mine runs at 24/7 due to some distributed computing projects, the chip will quickly heat up to 150 F or 64 C, with the air conditioner on for 68 F room temperature
Although I understand heat is an issue with virtually all new processors have heat issues seeing as the manufacturers are pushing the boundaries of silicon, I am very annoyed that Intel did not even bother to do anything about the problem with an obviously defective batch of chips, there was no offer for a 775 socket chip to replace the troubled 478 socket chip, there was no price break, and they did not even admit there was a problem until several months after the fact. Despite the fact that I can keep the chip at a semi reasonable temperature the 6000+ RPM fan makes the whole case very loud and is rather annoying over time.
If I had a socket 775 chip I might recommend it but seeing as I have a crappy 478 chip and I am in college and have no real means of replacing it anytime soon this is a terrible investment for anyone looking to buy an upgrade for their 478 socket processor.
