E8600 wont run at rated speed?

post #1 of 9
Thread Starter 
cpu - intel core 2 duo e8600 3.33ghz
mobo - Asus p5n32-sli premium
ram - crucial 2gb ddr2 800mhz x4
gpu - nvidia geforce gtx550ti 1gb
psu - thermaltake 700w

alright so, installed an e8600 in the pc
everything boots alright, open cpu-z
cpu is running at around 2.3ghz (cant remember exactly)
went into bios and tinkered with the available overclock settings
and managed to get it to the rated 3.33GHz

cpu appears to be at a steady 50c +/-8C at minimal load, with and without bios overclock settings altered.
so i purchased a new cpu cooler, all around better than stock cooler
temps stayed roughly the same
i removed the cooler and reapplied the thermal paste, two or three times.
pee method, smearing thin layer over cpu , pee method again


so my questions


why am i required to overclock the cpu to achieve the rated speed ?

is that a safe temp for my cpu to idle at?
is it possible that im getting false temp readings?

i apologize if i am missing any key information needed. unfortunately i currently dont have screenshots of cpu-z, hardware monitor stats

You may need to update the BIOS to the latest one so that it has the correct microcode for the E8600.

i updated the microcoding myself
because initially my board didnt support it at all
found a guide to update the bios while looking for a modded bios that would support it
p5n32-sli deluxe supports the cpu fully
p5n32-sli premium does not
little to no difference between the two boards physically

They have different chipsets. Both are pretty old, even for the 45nm Core2 Duo.

yeah kinda old indeed
but free and something to start building my roommates pc with
would that affect the processing power of the cpu that drastically? dropping its speed by 1GHz?
i was under the impression that updating the microcoding would make the mobo compatible with all processors that fit in the socket ( in this case LGA775)
post #6 of 9

Could you run a CPU benchmark like CineBench or Geekbench and monitor CPU speeds? I'm also interested in seeing how your CPU achieves 2GHz (6x rated FSB or 10x nominal 680i FSB).

 

I had/still have a 780i motherboard and I remember that FSBs above 1600MHz required overvolting the NB. X38, P45 and X48 were much better for 45nm chips.

No, you need the microcode for these CPUs in particular. I think this was something that was only available for the nForce 680i boards and higher. It might have been for all nForce 600 series, but I distinctly remember having to get the microcode from EVGA's website for my EVGA 680i SLI motherboard (not to be confused with the GTX 680 lol) and being told that I was lucky I didn't have one of the lower model nForce 600 boards. I had an E8400 and it wouldn't work at all in my board until I had the microcode, but once I had it, the CPU worked perfectly and I had it overclocked to 4.0GHz.

I dug around a bit and found a penguin dual core e5300
I looked up the cpu compatibility and I believe it Checks out
I noticed differences in my RAM but I don't know how that actually works out
Differences
USA vs China
I believe it's the revision number that's different as well
But you can see in the picture
I'm having trouble finding specs for the timing
post #9 of 9

Did you mean Penryn?

 

Anyway, yeah I don't know... I wouldn't mix two unknown memory modules. One could require 1.8V while the other one could require 2.2V. Y'know what I mean? However, both of my search results lead me to the same pages, pretty much:
