Just went to 3.5GHz (10.5x333) @stock Vcore using the Q9550 stock HSF in first attempt. At full load (folding) temps are around 55-58C. This is the SLB9Y (R0 stepping). Will let it run 24 hours and if stable then will try it with one of the many Intel stock HSF I have - probably the one that looks beefiest in size and fan power; and see if the older bigger HSF is better than the newer slim ones. Then later will push speeds higher.

Am getting <60C with my dinky stock HSF already In any case, if I can achieve a decent OC with the stock HSF, I'll be satisfied as I don't want to spend any more $$ on aftermarket coolers. If I really need to, I can swap in my NT06.

wow.. yr temperature readings are nice.. 3.5Ghz onli 58°C max.. but have u tried 100% full load constant? stress test or burn test? i never do folding so i dunno how much processing power they use..

any difference between Q9550 HSF n E7400 HSF??

Folding uses 100% constant CPU loading. The Q9550 HSF is marginally taller, has a round copper base (E7400 is full aluminum) and 7.2W Delta fan (E7400 has a 2.4W Nidec fan).

aw.. i see the difference now..

mine is 66°C max @ 3.2Ghz.. yrs 58°C max at 3.5Ghz.. hazairi 67°C @ 3.65Ghz with CM TX2

mine is even higher....huhu...almost 70C at 3.3Ghz now i'm just running the proc at stock speed.. even at stock speed my temp cn reach 62C when playing games..

yr's is E7300 ma.. 70°C at 3.3Ghz is ok wat. provided u r using stock cooler la.. but stock speed at 62 is kinda high.. play during noon hours?

His 58C was on Core 2 Quad. U can't compare it with E7400.

Edit: oh, when i read correctly, actually he is using Core 2 Quad's HSF with E7400..

guys, me just purchased a e7400 and noticed that the stock vcore is quite high; 1.30v. may i ask what is the stock vcore for this proc?
temp on idle is 45C even with BTVX. something is not right, its even higher than my previous Pentium D 930. pls advise. thx

Your idle temp is quite high. My idle temp even when I used the stock HSF was just 42C. Your stock vcore is high too. Stock vcore should be 1.22v. Where did u check the statistic?

bro i resolved the prob dy.
vcore went down to 1.18v after i restarted and enabled C1E in bios, together with speedstep kicks in (speedstep does not work before i enable C1E, which reads 1.30vcore and constant 10.5 multi).

Good. Now try to OC your CPU. Run Prime95 test and see if it's stable. If got prob in the program, u can slowly increase the voltage..

333x10.5 prime 6 hours passed with stock vcore bro. good or bad?
tot of doing 400 fsb but couldnt get the right memory divider. well, this mobo doesnt hv much option on memory divider. i guess wat i paid was wat i get

3.5GHz is the same as my E7400 also at stock Vcore and been running stable at full load 24/7 for past couple of days.

if i wan to go for 3.6Ghz.. u guys think is it better to

343 x10.5

or

360 x10

how does a multiplier affect the stability of the proc?

i would personally opt for higher fsb if the mobo permits it.

Here is mine.

3600MHz (400 x 9) PL 8 @ Stock VID



-pWs-

my mobo is capable of doing 500.. juz see whether i can hit it onot..

from yr picture.. looks like yr proc stepping is same as mine.. it shows R0 in cpuz.. but it shows E0 in Everest.. anything to clarify me?

anyway, nice clock u got there.. i might try 400x9 if i get pass 360x10.. waiting for my cooler to arrive..

Another update from me.

3825MHz (450 x 8.5) PL 8



-pWs-

cool bro. 3825mhz on stock vcore too?

i think not.. from his screen shot is 1.304 i think..

stock is 1.20V if not mistaken.. rite -pWs-?
