I'm currently reviewing a monster rig right now but while everything is still being set up, a fellow istoryan was kind enough to do a straight swap with my E4500. The item that was swapped?
Its a wolfdale
!!! Known for its low voltage, low heat, awesome performance and overclockability (if there's such a word). This baby has a VID of 1.2875 volts which is pretty mainstream for a wolfdale.
Before I started my overclocking, I went ahead and verified if the sensors are okay on this thing and this is what came up:
Yep, its one of those with sticky sensors as UncleWebb (creator of RealTemp) would call it. Basically, the sensors wouldn't move up below 41c but can go beyond it which means that I wouldn't know what my idle temps are. A similar analogy is like driving a car and seeing the speed at 41 kp/h even though the car is barely moving. But that's not really something that would scare me from overclocking this thing.
The test setup:
E5200 or basically 45nm processors' absolute maximum voltage is 1.45 volts, take note of the word absolute, beyond that, should be extreme cooling
and the risk of permanent damage brought about by electromigration in an extremely shorted amount of time.
Tired because I just got home from work (graveyard shift), I hard set the voltage to the processor's VID to 1.2875 volts instead of Auto and increased FSB to 266 (conroe style
) leaving the default multiplier to 12.5, if you're good in math the resulting clockspeed would be 3325 MHz or 3.3 GHz. I then configured the memory to run at rated specs (DDR2-800, CAS4) in which the resulting ratio is 2:3 (266 / 2 * 3 = 399 rounded off to 400, yay!).
All other voltages are set to default except for the memory where I tightened the timings at 4-4-4-12 with a 2.0 voltage (paniguro lang
). Now, prime95 is an awesome stress testing utility but I didn't have the luxury of time so I went for something fast -- Intel Burn Test Utility which uses LinPack x64 and this is what I have:
5 runs and its stable with the highest recorded temperature 52c. Take note, this is with stock voltage settings, no loadline calibration.
And now, the obligatory SuperPI 1M:
I'll be pushing this chip as far as it can go with voltage limit up to 1.42 volts (.03 volts short of the absolute high
) but the Raven awaits for the review. I'll make sure to update this thread though but I can see a bright future of this processor. Stay tuned....
