Should I go for 3.6ghz with a PHII x 4 925 2.8 non-BE

[king smp]

Cpu: 925
Name: King smp
Stepping: C2
Frequency: 3500
ref*multi: 250*14
CPU voltage: 1.525
CPU-NB: auto
nb frequency: 2500
NB volts: auto
HT freq- 2500
HT volts-auto
RAM: 8GB 1333Mhz DDR3 8-8-8-24-1T @ 1.5V Kingston HyperX Genesis DDR3-1600 CL9
Motherboard: Asus M4A77TD AM3 770
Cooling: Air cooling/Hyper N520
OS: 7 64-bit
max CPU temp- 52c in 70F room after hour Prime95-64bit

I was thinking of dropping my HT and NB frequencies down along with ram speed but then I wondered that lowering them down to increase 100mhz in CPU speed would actually hurt performance
I figure that 2.5ghz HT with 8-8-8-24 1t ram is actually better than a 100mhz cpu increase???

And in reality, is the 100MHz going to be seen? Maybe back in the Celeron 300MHz days when we were OCing them to 450MHz Yeah, I'm that old.

I know the feeling
I am 41 myself
I think I just want the higher clock speed to say I did it
really a 2500 HT/NB with ram at 1333 is better I think
overall system performance is probably higher due to better bandwidth

I had 3.6ghz running desktop and then crashed at the seventh test in P95
so it was a teaser

 

[scottiemedic]

I'll take stability over 100MHz anyday (that's how 38 year olds think at least haha)

 

[king smp]

I know
I should be happy with 3.5ghz
700mhz OC on a non-BE C2 Deneb is reasonable
but I had it booting into desktop at 3.7ghz
so have been tortured ever since LOL

Best answer selected by king smp.

as a side note I have the 925 at 3.5ghz and CoolNQuiet enabled so it goes from 2ghz to 3.5ghz and ram set to 1333 8-8-8-24 1T
does a 4.15 in Cinebench 11.5 (I7 1st gen is in the 5s)
thanks for the help old man

I wouldn't bother trying to clock any higher unless you were to get better cooling first. Best to try and stay below 55­°C with those chips. Is it stable with your RAM at 1666?

 

[king smp]

I do stay below 55c (52c after hour with P95) with my Hyper N520 in 70F room
RAM isnt stable at 1600
set it to 1333 8-8-8-24 1T

 

[bardacuda]

Right, but what I was saying was IF you were to clock higher. Since if you did you would need to add more voltage and therefore have higher temps and you are already at the upper safe limit. Without upgrading your cooling then you should probably call it a day and be happy with your current OC.

 

[king smp]

yes I am good with the 3.5gh
especially I got is stable with Cool n Quiet working
idling at 2ghz really helps my temps
voltage varies from 1.28 to 1.52
with 1.312 being the normal voltage

considering the PHII 925 Deneb is only a C2 and non-BE
getting a stable 700mhz OC is respectable I guess

cant get ram to go DDR3-1600 with the 3.5ghz OC
it is stable at 1600mhz with a 3.3ghz OC

going to open new thread asking which is better
3.5ghz NB/HT 2500mhz DDR3=1333 8-8-8-24 1T
or
3.3ghz NB/HT 2350mhz DDR3-1600 9-9-9-24 1T

wondering it the memory bandwidth increasing offsets the 200mhz CPU speed loss

I will post link to thread if I can
