AMD® Phenom™ II Overclocking Thread

Hello, I need a bit of help with some tweaking settings for the asus m4a88td-v evo motherboard when overclocking a x6 1100t, first of all are their any general recommendations people have for overclocking on this mobo/processor? and secondly even when having a mild overclock from 3.3 to 3.6ghz it pushes the vcore to 1.5v when under load, which is far too much for this overclock. The auto vcore states it is at 1.4v, and when I try to set it in manual it doesnt seem to accept the change, also, would you recommend disabling LLC or using LLC? any other tips would be hugely appreciated, as i've seen a few people say that the vcore can be fussy on this motherboard, thank you for the help it's hugely appreciated :)

955 BE £60 brand new for another site, i'm impressed. Quick 30 minute test.

SNIP

24c room temp with an Antec Khuler 620 in push/pull.

Buchtis, thats bad man, 78oC, suprised your chip hasn't gone pop yet, FYI, for prolly the umpteenth time in this thread, the Cpu temp sensor does not work on AMD Phenoms, you have to read from the TMPIN0 for cpu,

Also, mine was Custom water, not some Antec ***** :p
 
Help please :)

O.k. so I have found a stable clock at 3.6ghz with the following settings

Bus speed 225mhz
Multiplier 16x
CPU-NB 11x
Cpu voltage 1.375v
CPU-NB voltage 1.2v

However, my CPU seems strange and it doesn't like to be overclocked by just raising the multiplier an I could only reach 3.6 by raising the fsb as well.

I have gone watercooling and have been trying to get above 3.6ghz. I tried 3.8GHz with the following settings

Bus speed 230mhz
Multiplier 16.5x
CPU-NB 11x
CPU voltage 1.5v
CPU-NB voltage 1.25

I originally tried with 1.45v Vcore and I could only get about 30mins of P95 before I BSODded. I then tried bumping it up to 1.5v Vcore and managed about 1.25hours before it Bsodded again. Is 3.6GHz my chip's limit or am I doing something wrong?

HELP!!!!!!!

Cheers :)

pretty sure you've got a C3 stepping chip guitarman?

leave the Cpu-NB at default,
HT Link to 2000mhz
clock speed 200
change the multi to 19
1.450Volts

boot, stress, pretty sure that should work :p

What revision is it?

Mine went up to 4.5Ghz too but under load the temperatures were immense. :(

How on earth does this happen? My 965 (albeit a C2) will only go to 3.8ghz stable, boot at 3.9ghz and will last for one SuperPi 1M run at 4.0ghz before it dies.

That was on my old motherboard as well, which I found to be a terrible board. (VDroop on my was so bad you could set to 1.55v, but it would droop as low as 1.475v).
 
not sure Muel, mine was a C3 955, bloody awesome chip, still working strong too lol
guess it's your GA board too, from memory when my chip was doing 4Ghz + at 1.55V it would some times droop to the early to mid 1.5's but not loads,

Benching at 4.4Ghz under water with 1.6v saw it droop to 1.585, but everything still remained pretty solid :D
 
This board has been fantastic tbh, vcore has been rock solid in all the tests I've done. I was talking about my old board, which was an Asus M4A79XTD Evo.

I won't be bothering to push this chip. It's an aged C2 that's had a lot of hard use, so it won't be able to clock as high as it once could (I guess anyway?).

Apparantly BD will run in this board, so I'll probably hold off any upgrades until I find out how overclockable that combo will be. If it doesn't work too well then I'll probably just get an 1100T as cheap as I can find one. :)
 
must be your C2 chip then, thats the same board i was using up until a few days ago, got my C3 to 4.5Ghz bootable, never blinked until my wc loop leaked over it somewhat lol
 
For a C3 955 do you only need to adjust the cpu vcore and multiplier to overclock?

I'm trying to push 3.8-4ghz and can't seem to do it. Using GA-890fx UD5 mobo with antec 620 cooling.

3.6 is stable at base voltage but for 3.8 I need 1.5vcore and after passing a few hours of stress test I just had a bsod.

I tried using 4ghz 1.6vcore and it would bsod within 15 secondsof prime95, temps not reaching 55c

So just wondering do I need to adjust the nb vcore or cpu-nb voltage ?

I'd just up all the voltages to their maximum, then keep increasing the clocks until you hit the limit. :P

Keeping an eye on temps the whole time obviously.
