Hi all, I built my desktop almost 10 years ago. It was an i7 920 with an Asus P6TSE board. It has served me well over the years with never any hiccups in performance. I've never OC'd it. I currently use it primarily as a Plex server/HTPC with some sparse gaming every now and then. It played GTA-V pretty well, although I honestly don't know how much longer anything new will be playable on it.
So anyway, I read about the huge drop in price of old Xeon processors and grabbed an X5670 off eBay for $20 (and another 8 GB of RAM). Figured it might extend the life of this rig a bit with the two additional cores at 2.93 GHz, versus the i7's 2.66 GHz. I updated my BIOS and dropped in the new CPU, cleaned off the decade old thermal paste (dust now, I probably should've applied fresh a long time ago) off the stock Intel heatsink/fan from my i7 and booted the computer up. The computer came right up and shows 6C/12T at 2.93GHz!
Cinebench 20 score went from 734 to 1484! Idle temps were ~25C with loaded temps ~65C.
Having never overclocked before, but hearing these CPUs were good for OCing, I looked around online and found this thread https://www.overclock.net/forum/5-in...-asus-p6t.html
. I followed the post below exactly and ended up with 3.74 GHz and a Cinebench score of 1668.

When changing the BCLK Frequency, this will affect the DRAM Frequency, UCLK Frequency, and QPI Link Data Rate alongside the core frequency. With the P6T motherboards, however, the only multiplier they'll display is the CPU Ratio Setting (core multiplier) if you manually set it. Multipliers for DRAM, UCLK, and QPI are displayed as what their final frequencies (Data Rate for QPI) will be.
To get started, you can set the BCLK Frequency to 170 and CPU Voltage to 1.25. Now set DRAM Frequency, UCLK Frequency, and QPI to the lowest values presented and set QPI/DRAM Core Voltage to 1.25 so that tests can be focused on core stability for the moment. PLEASE NOTE: These settings are merely suggestions to get you started. Optionally, set DRAM Bus Voltage to 1.5 if you want to explicitly tell the motherboard the voltage (1.5 volts in this case) to supply to RAM. All selections in DRAM Timing Control are fine being left as [Auto].
After about 10 minutes of Prime95, the temps jumped from their idle temps of ~30C to 90C! This is too hot, right? Is there some further tweaking I should do to what I've done to bring down the temps? I'm not looking for world records or anything and am happy with the 3.74, but if I have to go down some to get the temps into a safer place, I'm fine with that. Thanks for any tips you can give!
