[SOLVED] Which of my processors is best to overclock with a G31 Chipset? (See List)

[hypercrasher128]

I want to overclock my processors with my G31 chipset motherboard (for fun sakes)
FSB Limit @ 1333MHZ (1666mhz doesnt work with my motherboard)

These are my processors
Pentium Processors

E2140
E2180
E5400
E6300
E6800

Core 2 Duo

E7400
E7500

I just want to know which of them is OC friendly?

Specs
ECS G31T-M7
DDR2 CL5 667MHZ
GT 520
TRANSCEND SSD
800W Corsair TX850M

(UPDATE: Only 2 processors reached 3.5 GHZ, the E6300 and E7500)

With that setup it will not be the CPU that limits your OC but the motherboard/chipset, all of them should be able to run somewhere between 3.5-4.0 GHz (depending on silicon lottery ofc)
You won't be able to go much beyond maybe 360 FSB with the best of luck on G31. Around 330-340 should work, assuming you can set the FSB. That is also where your 667 RAM will run at 1:1 ratio, and the Intel chipsets won't allow anything lower anyway.
Try starting with the one with the highest multipler, in that case the E5400 or E6800


On these, don't go over 1.45-1.5v if you want it to stay alive. (65nm chips (like the Q6600) some do 4 GHz, but expect more in the range of 3.2-3.6 with moderate voltage)

E2140 (could oc to maybe 3.0, which means FSB around 330-340)
E2180 (same as above, doesn't clock much higher, but should reach it with around 320 FSB)


On these not over 1.35-1.4v (45nm chip (like the E8400 or Q9550) They can do 4.0-4.2 GHz, but 3.6-3.9 should be archivable with moderate voltage)

E5400 (high multi of 13.5 plus low FSB of 200 means it should go quite a bit before the board limits)
E6300
E6800 (12.5 multi means 3.5-3.7 is possible with 280-300 FSB, but also already quite high clocking lowering the multi to something like 9-10 would put you around 3.0-3.5 with 340-350 FSB)
E7400
E7500


or you could simply do a BSEL mod to trick the board into thinking the chip is a faster one. (tutorials are out there, but you basically put tape over certain pins) It takes most of the fun out of ocing the platform, but is easy to do even on boards that don't offer all the settings for manual oc. That would mean:
E2140 (200x8 = 1.6) ->(266x8 =2.12) -> (333x8 = 2.66)
E2180 (200x10 = 2.0) -> (266x10 = 2.66) -> (333x10 = 3.33)
E5400 (200x13.5 =2.7) -> (266x13.5 =3.59) -> (333x13.5 = 4.49)
E6300 (266x10.5 =2.8) -> (333x10.5 = 3.5)
E6800 (266x12.5 =3.33) -> (333x12.5 =4.16) here manual OC is needed.
E7400 (266x10.5 =2.8) ->(333x10.5 =3.5)
E7500 (266x11 =2.93) -> (333x11 = 3.66)

stock speed - should work fine - possible, depends on how well your setup does - with lots of luck/on a better board - won't work without better board & cooling

Thanks, but is is there any thing that in need to change in the bios like SpeedStep, Thermal Management?

if i tried to manual oc my processors, is there any settings in the bios that i must change ?
