How to overclock / Xeon e5645
How to overclock / Xeon e5645
Hi everyone!
I just acquired the old computer of my brother with these specifications:
GeForce 1060 6 GB
Xeon e5645 6 x 2,4 (turbo: 2.67) GHz
12 GB RAM
Mainboard: Gigabyte ga-x58a-ud3r
CPU cooler: Revoltec lga-t1 (95 mm)
Because the original CPU speed is quite low, I plan to overclock it. But since I’m not very familiar with this process and haven’t found any tutorials online for this particular CPU, I’d really appreciate someone’s guidance on how to achieve around 3.2 GHz. Thanks!
There are CPUs available with quicker clocks that will perform well right away. Some of these are unlocked multiplier CPUs. Here are a few examples of such systems. The first one is boosted to 4.4GHz

However, this setup isn't straightforward for overclocking. You should review it carefully before proceeding.

Two approaches exist. The BCLK method doesn’t need an unlocked CPU, but it demands significant adjustments to memory speed and QPI link, making the process quite intricate. Voltage control is also less direct here. Faster RAM is necessary.
Alternatively, using an unlocked CPU such as i7-980X, i7-990X, Xeon W3680, or W3690...

Two overclocking approaches exist. The BCLK technique doesn’t need an unlocked CPU but demands significant adjustments for memory and QPI connections, with indirect voltage control. Higher-speed RAM is necessary.
Alternatively, using an unlocked CPU such as i7-980X, i7-990X, Xeon W3680 or W3690 works well. These offer base clocks between 3.33 to 3.47 GHz. The Xeons support DDR3-1333 RAM, while the i7 models use DDR3-1066. The W3680 provides the best balance. Performance remains stable with no impact on memory or QPI speed. Simply increase the multiplier and adjust current limits. For beginners, this method is advisable. However, experimenting with the first approach is free if you wish.
RAM configurations on these systems are typically 3-channel, which is a notable benefit.
I believe overclocking these units is worthwhile—it holds significant promise.
The issue is that the 980x and 990x models are extremely expensive on eBay for such an old system. I’m aware of this because I own a 980x on an Asus Rampage III Extreme running at around 4.0Ghz. You’ll need to keep the multiplier at 19 and gradually increase the BLCK until it stops working. Then slightly raise the CPU voltage, test again, and continue until you reach either a temperature limit, a voltage limit, or you’re satisfied with the performance. It’s also simpler to overclock these CPUs when they have only three RAM sticks installed; filling all six slots adds extra strain on the memory controller, which you’ll need to manage carefully to achieve a stable overclock.
The memory controller is integrated into the CPU. Lower-end CPUs typically feature slower RAM speeds as well, usually DDR3-800. High-end models support DDR3-1333 and even 1333 on top-end Xeons.
