Hi all,
I completed my i5 overclocking build. I have detailed some of the mods and build progress here:
http://jazzvine.blogspot.com/2010/01/computer-build-3.html
But I will put some photos and progress and build cover things up here.
So I started out with this lot:
And ended with this:
In the middle I swapped the 92mm cooler fan for a 120mm Akasa Apache one:
I cut some air vents with an angle grinder, also cut the 18CM hole for the side fan:
I cushioned my fan mounts (to reduce vibration noise):
I kept the wires reasonably neat. 120mm intake front, 120mm output below the PSU, 180mm side fan, 120mm CPU fan and 120mm PSU fan:
Some HL2 testing (bro's monitor):
Right, so I had it at 4.2GHz, and it was fine till I used the Intel Burn Test - it got hotter than I wanted (cores between 74 and 80...), I just wanted to see if it worked - I will upgrade to water cooling at some stage because I reckon this chip will be good at 4.4GHz.
I have tweaked it, and settled at 4.1GHz. Temps after 1hr45 of Prime95 heat teating:
It spent the most of the test between 66 and 71*C, just the odd peak or fluctuation.
And in the Burn test it peaked at 82*C for the shortest time, the chip temp was 69*C according to SpeedFan:
The Burn Test is severe, man, I didn't like running that! Anyway, some specs:
Vcore: 1.31v measured by CPUID (BIOS set @ 1.318750 I think)
Vin1: 1.62 - CPUID (BIOS was set to 1.6)
Bclock: 216MHz
Multiplier: 19x
DRAM multiplier: 6x
Core Speed: 4104MHz
DRAM Speed: 1296MHz
DRAM Timings: 9, 9, 9, 24
All extraneous power BIOS power functions, power save, turbos etc etc... turned off.
At 4.1GHz my CPU benchmark was 7115.5 which I am dead pleased about! I ran a bunch of stress tests. OCCT for 4 hours, Prime95 - 2 hours on large FFTs, 10 mins on small FFTs (I read that 10 mins should show whether the system would cope or not), hours on blend. Intel Burn Test - I ran the default 5 cycles, and it pushed the chip hard, but it was fine. I also ran SuperPi and LinX.
I am monitoring heat with:
SpeedFan
Core Temp
CPUID
Benchmarking with Performance Test 7 on evaluation.
Anyway, this is my first build and my first overclock attempt. I know the temps were/are on the higher side. Further with it being winter my room is pretty cold, so I will be doing some gentle testing with the room heated to "summer" temperatures to see the impact on the CPU heat - this will inform my decision for the summer as to whether I need to upgrade my cpu cooling or lower the clock speed.
I appreciate any criticism/comments. I did a good bit of reading on all of this stuff and I hope that I haven't made some building sin somewhere
Also: Replaced the TIM with Akasa stuff.
Final spec then:
i5 720 @ 4.1GHz (216x19, 1.313Vc).
4GB Corsair DDr3 @ 1296MHz (216x6, 9,9,9,24 timing, Vin1 1.6v).
Gigabyte P55-US3L
OCZ 500W PSU
Radeon Sapphire 1GB 4350 card (go on, laugh!!) - 650MHz GPU, 450MHz Memory clock for now.
Samsung Spinpoint F3 500GB 16MB cache
Samsung 22x Dual Layer DVD drive
Arctic Freezer 7 Pro with Akasa 120mm Apache fan mounted.
2x 120mm AC case fans, 1x 120mm PSU fan, 1x 180mm Akasa side fan.
Anyway, it has been an awesome learning experience and I really had a blast making this. Modding the case was good fun, especially seeing it look decent enough. Maybe a cold cathode tube would be nice
Cheers all!
