p4 overclocking
i know the number of p4 users is small here but i have a strange problem and wonderd if anyone else has seen this.
i have a p4 2.53 c1 stepping running at 3153ghz. i just installed some xms 3500 cl2 memory (had samsung 3200 cl2.5 before )and increased the fsb from 166 to 170 giving me 3230ghz. i ran sandra cpu benchmark before and after and the benchmark was the same. the strange thing is it was only 8196 mips. when i first setup this system up it was running faster at 9011mips. i have lowerd the core volts to 1.52 and the system is running fine with no lockups. on my old benchmark i would have had the volts at 1.5v or higher. could this be the problem ? Lee :shrug: |
Maybe the CPU is throttling off due to overheating ?
|
system temp 25C
idle temp 38C load 42C i am looking into the by spd settings on my p4pe. it looks like that could be one problem. |
SPD settings are programed into the RAM~sticks themselves, not the BIOS/mobo. You're best off setting it up yourself...
|
Yes, spd is programmed inn thoses sticks. so set them up yourself.
If that is done, right and u still have problems i would think throttling or that your software is a bit "¤)(/#(¤/%" :) No spyware proggies that have gone past you? -P- |
i did a bit of searching last night and found that the xms 3500 on chip spd is the same as 3200 so i set them myself to 2-3-3-7. I also found that the p4pe i have has problem with high fsb in memory slot 1 so i will change that too.
just before i switched of my pc last night i ran one more sandra benchmark and found it was 9003 mips. This morning back to 8000. |
I have my 1.6a "Northy" at 2.59 the other day...
Temps were 32 deg cel for the chip case was 34 deg cel... Using air cooling setup... I'll post pics soon.... |
after installing sandra max today i found my benchmarks are close to what they have for 3gig and 3.2gig p4 non HT so i am happy.
also have the xms 3500 at cl2 424mhz fsb 170 core volts 1.55 speed 3230 i have a little more left on the ram so after giving it a good bashing i will try higher. cant wait for my cascade as my temps will drop giving me even more room to improve. I did have a close call as the ehiem 1048 i have stopped working and my bios temps shot up to 86C !!!!!!!!!!!!!!:eek: I have changed the 1048 to a aquabee 1000 l/h for the moment. |
