Today I borrowed an Athlon XP 1700+ (Palomino) from my friend. The CPU is reported "model 6, stepping 2" in WCPUID and CPU-Z. I wanna know how far "stepping 2" Palominos overclock with cheap cooler and 1.85v?
Now here's my overclocking experience with this CPU. I used a cheap alluminium based coolermaster HSF (no thermal pad/paste) which is fairly silent. Rest of the system:
ABIT NF7 v2.0
2 x 256 MB Kingston Value RAM PC2700 (rated CL2.5 for PC2700, CL2.0 for PC2100)
Gigabyte Radeon 9000 (not overclocked)
300W "Generic" PSU
2 case fans
CPU Temp (full load): 54C at stock speed & voltage, 59C at 1540 MHz (1.85v)
Special note about CPU voltage: Working CPU voltage with this CPU was always lower than the voltage set in BIOS. For example, The CPU ran at 1.71 to 1.73v when it's 1.75v at BIOS. In case of 1.85v, it ran at 1.81 to 1.82v
I used mainly prime95 for stability test:
<b>1470 MHz (stock speed), 11 x 133 MHz, 1.75v (default), memory sync with FSB/2.0-2-2-5</b>
Running prime95 since last 1 hour , no crash. Ran few benchmarks (3DMark 2001/2003)
<b>1540 MHz, 11 x 140 MHz, 1.80v, memory sync with FSB/2.0-2-2-5</b>
prime95 torture test crashed within few seconds, benchmarked system with 3DMark 2001 (1 time), played Mafia for ~1 hour
<b>1540 MHz, 11 x 140 MHz, 1.85v, memory sync with FSB/2.0-2-2-5</b>
prime95 torture test crashed after 2 minutes
<b>1540 MHz, 11 x 140 MHz, 1.85v, memory sync with FSB/2.0-3-3-6</b>
prime95 torture test crashed after 12 minutes
<b>1575 MHz, 11 x 143 MHz, 1.85v, memory sync with FSB/2.0-2-2-5</b>
prime95 torture test crashed within few seconds, unusual windows explorer crash
<b>1575 MHz, 11 x 143 MHz, 1.85v, memory sync with FSB/2.0-3-3-6</b>
prime95 torture test crashed within few seconds
<b>1575 MHz, 11 x 143 MHz, 1.85v, memory sync with FSB/2.5-3-3-6</b>
prime95 torture test crashed within a minute. This time I also used 3DMark 2001 (inf. loop) for stability testing (640 x 480 x 16 bit, Software T&L for stressing particularly the CPU). It crashed after with 20 mins.
The CPU I regularly use is a Duron 1 GHz, overclocked @ 1.15 GHz (morgan core, model 7, stepping 0). Rest of the system spec is same (most possibly the HSF, too. Also didn't use thremal pad/paste). In case of this CPU, the working voltage doesn't vary from the voltage set in BIOS. CPU runs at 51C under full load (at 1.15 GHz, 1.8v). Here's the overclocking result of this CPU-
<b>1000 MHz (stock speed), 10 x 100 MHz, 1.75v (default), memory sync with FSB/2.0-2-2-5</b>
prime95 torture test ran stable for 12+ hours (didn't crash, I stopped the test)
<b>1100 MHz, 11 x 110 MHz, 1.75v (default), memory sync with FSB/2.0-2-2-5</b>
prime95 torture test ran stable for 12+ hours (didn't crash, I stopped the test)
<b>1150 MHz, 11 x 115 MHz, 1.80v, memory sync with FSB/2.0-2-2-5</b>
prime95 torture test ran stable for 12+ hours (didn't crash, I stopped the test)
<b>1200 MHz, 11 x 120 MHz, 1.90v, memory sync with FSB/2.0-2-2-5</b>
didn't run prime 95. Crashed while installing a driver
Now I want to know how far the AXP can with my cooling? Why the CPU voltage is always lower than the voltage set in BIOS (for this particular CPU)?
