Abit AN7-AMD XP2500 Mobile-Thermalright SP97

[ProfessorFate]

Abit AN7 motherboard, Mobile Athlon XP2500 CPU and a Thermalright SP97 Heatsink assembly for some overclocking fun.

System Configuration
Abit AN7 nForce2 Ultar400
AMD Mobile XP2500 CPU
Thermalright SP97 Heatsink
Thermaltake 90MM TT-9025A-2B Fan
BFG FX5900 Video Card @ 470/980
Western Digital 36GB Raptor on Sata 1
2X256 OCZ 3700 Gold v1
Enermax EG465P-VE 431 watt PSU
Windows XP Pro SP1
Nvidia Forceware Drivers Version: 56.72

-------------------------------------------------

I found this combo to be rock solid with a 12.5 multiplier and a 200FSB setting for a CPU speed of 2500MHz. So just under a 700MHz overclock, with the CPU Vcore set to 1.813 in the bios. With this setup I never saw a CPU temp over 42C under load.



Benchmarks

Benchmark settings as follows:
12.5 X 200 = 2505MHz CPU
DDR set 3:3 for 400MHz speed @ 2.95 volts
Cas Latency 2.0
Precharge 2.0
Ras to cas 3.0
Active Delay 5.0


----------------------------


X2 Rolling Demo
Default settings = 107.13

---------------------------

Total score = 43853

-------------------

Super_PI
1M = 42 Sec
2M = 1 Min, 35 Sec

--------------------

CPU Arithmetic Benchmark - SiSoftware Sandra
Dhrystone ALU = 9565
Whetstone FPU = 3888

-----------------------

POV-Ray 3.5 Benchmark v1.02
Time = 28 min, 30 sec

------------------------------

Allright the system has yet to break a sweat so I'll crank it past where I'm comfortable running it on air for some Benchmarks.
I'll go mostly CPU intensive benchmarks.

Benchmark settings as follows:
13 X 205 = 2671MHz CPU @ 1.93 Vcore
DDR set 3:3 for 410MHz speed @ 2.95 volts
Cas Latency 2.0
Precharge 2.0
Ras to cas 3.0
Active Delay 5.0


---------------------------------


X2 Rolling Demo
Default settings = 111.34 FPS

---------------------

Super_PI
1M = 39 Sec
2M = 1 Min, 30 Sec

------------------------

CPU Arithmetic Benchmark - SiSoftware Sandra
Dhrystone ALU = 10197
Whetstone FPU = 4207

---------------------------

POV-Ray 3.5 Benchmark v1.02
Time = 27 min, 1 sec

-------------------------------

Max temp with these settings 52C

--------------------------------

Pretty nice mobo/Cpu combe for under $200.

Nice OC. That's the memory I had considered getting myself, but they were out of it yesterday when I ordered, so I went ahead and got a gig of the Mushkin 2-2-2 "Special". How high will that memory run at 2-2-3 timings? Anyway, hasn't anyone told you that with the nForce2 chipset, you'll get better performance running your memory at 2-2-3-11 timings than at 2-2-3-5? Try it, do some memory-intensive benchmarks (like SuperPi), and it will be slightly faster.

edit: It will only be faster at 2-2-3-11 above 200mhz (or close to it), not below.

Nice OC those are some very low temps. I'm on water, pushing less volts (1.75 @2640Mhz) and read 55C underload. Of course I have no fans in my system just passive rads.

Where did you plug in the CPU fan / how did you orient the heatpipes? I have my heatpipes point towards the RAM slots, but it gets in the way of the CPU fan motherboard power port.

myocardia, yeah I've read that too, but my Intel habits made me forget to compare that I guess. I ran Super_Pi 2M and got the same times, but Povray picked up about 45 seconds. Thanks for the post.

crimson117, I have the pipes pointed towards the ram too. It's very tight, but the wire does just slip by on my mobo.
