Amd Athlon x4 640 OC

post #1 of 16
Thread Starter 
Hello all

I've been reading myself up alot around this CPU and overclocking, sadly there are not many that have the same combination of CPU and MB as I have.

First off, I am running all stock cooling (air cooling ofcourse). And until I am to buy a new setup it will stay this way, I know that it severely limits my ability to overclock, but still there gotta be some room for me.

Aswell I have already overclocked it, though I haven't touched the RAM nor so many other settings than vCore and FSB speed.

System:

MB: MSI 770-C45
CPU: Amd Athlon x4 640 - stock: 3000mhz, OC: 3400mhz
Memory: Kingston Value 4GB DDR3 1333mhz
GPU: Gainward Geforce GTX 460 Overclocked
HDD: Samsung Spinpoint 500GB 7200rpm
PSU: Corsair TX 650W
OS: Windows 7 64bit

Anything that I should change? Screenshot attached as thumbnail under.

Turn off auto voltage, put it at 1.4 or 1.45.
Run prime and give us your load temp.
And, maybe it would be good if you don't overclock with your board.

Thanks for the reply!

If you mean the vCore I have already manually set it to 1.47v.

The temps in Prime95 tortur test is around 80-85c so that's way hot.


Edit; Under load while gaming it is sticking around 60-65c, never seen it above 70c.

... Are you kidding me?
Don't your computer crash at these temp?

Oh and, for most AMD CPU (athlon II and phenom II), it's recommended to not go over 60C...


Ok, 1.47 is high, really high for such an overclock (and on stock cooling), try it around 1.4 to 1.45.

Try a higher NB with lower multiplier.

My 635 runs at 2500 NB which boots up snappier.

@spikexp: No it doesn't, I lowered the vCore first to 1.45 then got BSOD after 5 secs in Prime95, lowered to 1.41 afterwards and would not boot. Set it back to 1.47 and it works fine.

@krabs: When saying higher NB and lower multiplier, do you mean that I should raise the CPU-NB core a notch or 2 up and lower the NB multipler or lower the FSB multiplier?

--

I experimented some and set manual voltages on NB, HT and vCore and it only gave me BSOD on startup. So now it is reverted back to the following:

vCore: 1.47
All other voltages on Auto
230x15 FSB / multiplier
HT and NB on x8 multiplier (to keep it under 2000mhz)

first thing is first, must upgrade cooler. i built a computer for an artist with that same processor, different mobo, but i used a tower style cooler (arctic cooling freezer pro 64) and after a bit of playing around, i was able to get 3.85ghz running on 1.43v and in prime95 it would slowly raise temps until it hit 60, then it would just stop.

i don't know all the settings, but you just have to kind of feel the chip out. start out at stock voltage, then raise the OC, then keep going slowly until it bsod's, then raise the voltage a lil more, and keep going. once you reach a speed you want, boot to windows, and run prime95, while keeping an eye on temps. if it goes above 60, kill it, and bump down the voltage. if it doesn't reach 60, you can bump it a lil higher. if it bsod's, you either need more voltage or a slower clock speed.

remember. more voltage=more heat. and a cold computer is a happy computer. upgrade that cooler. even if it is only 30 bucks, you can get a very nice one. in my computer i have the coolermaster hyper 212+, and it does a very good job keeping a phenom II x4 at 3.9ghz cool.

edit: don't do overclocking from inside windows, do it from within the bios. if you aren't very comfortable in the bios, then im sure inside windows will work, but you do get a bit more control in the bios from my experience.

Thanks for the reply Rocker!

I am entirely using the BIOS for overclocking, wouldn't use anything else without a doubt!

But when I'm playing it is keeping itself around 60-65c and I know that's a tad high but still under the safe load per AMD (max 71c).

Hmm... I just gotta mess around and see what I can get out of it, I can live with a core speed of 3400-3500mhz, but I personally think as others have said that my temperatures are to high aswell my vCore is to high for that clock.

A sideby question to anyone with experience of RAM regarding overclocking an AMD cpu, is my timings etc correct (see attached screenshot in original post)? I haven't done anything with it beside lowering it from 1.333 start to 1226 start.

Im pretty sure you could keep your system stable @ 1.4v or just below, 65c can bit a bit scary for amd o_o.

1.47 is still really high.

But it won't function when going drastically under 1.47 (I haven't tried 1.46 yet, but 1.45 won't work). :-s
