i also doing assignment..boring..and tried to oc my ancient rig...
CPU : AMD Athlon X2 4800+ @3.125Ghz 1.36Vcore (Stock heat sink and stock thermal paste)
M/B : XFX 750a SLI
RAM: 2x2GB Kingston KVR DDR2-800
GC : M/B on board GC
OS : Windows XP



kenot break brisbane 4800+ G2 record (second place only).. sad

TS, pls help me add my result to super PI 1M database..guess thats as far as i can go on stock cooler

Super PI 1M results
Score: 29.360

means its not stable i guess..mine also manage to complete superPI 1M after 3 try...( i guess the processor need some time to burn in at tat speed ) hav u check the processor temperature while its running?? if its too high sure will hav blue screen..

ur ram is kvr 667, the bios will select the best cpu:ram speed ratio to match it..and it will try to be less than 667 usually

ic..then it should be 400...maybe u can check in bios to set the ratio manually.
its better for ur ram to be lower frequency if u wan to overclock..cause as u increase the FSB, the ram speed increases as well..
too bad my motherboard dun hav option to set the CPU:RAM ratio..at 3125mhz my ram running 893mhz.. dunno is my ram kenot take it or my processor kenot take it..

bro..u using wat power supply?? +12V at 9.5V +5V at 3.03V??
u sure ur computer still working?? or the motherboard take the wrong reading??

ic..try play around with the memory clock multiplier in the bios..tat might help ur ram back to normal..u need a ratio of cpu/7
2800/7=400
2800/9=311 is ur current speed

AMD processor seems to always hav problem with the core temperature..mine core 1 core 2 report temperature was less than 20 degree when i was in a room of about 34degree..
get use to it bro..

I read some article they said that the 4th core was damaged physically to disable it..so probably for tis case was the thermocouple was short circuited only..

tat is wat Nvidia expert at..take a 8800gts 512mb, sell it as 9800gtx, then sell it as 9800gtx+ again...now they selling it as GTS250..
now..780 sell as 980..next come 250 again..haha..

how fun is it shinjun??
btw..might sell my XFX 750a SLI and X4800+ to fund for a 790gx and 7750 maybe..

low on budget bro.. thinking maybe not the time to sell also..now economy so bad...
but i open a thread already..if got good offer then will sell it..
