Could use a little help overclocking.

[jaguarmatt]

My motherboard came in yesterday along with my new heatsink/fan.

So, here's my specs:
Mobo- AM3 MSI 890GXM-G65
CPU- AMD AM3 Athlon II X4 630
CPU Cooler- Scythe - Big Shuriken
RAM- 4GB (2x2GB) Samsung 10600 DDR3 PC-3 @ 1333MHZ
PSU- 500Watt continious Rocketfish Gaming

Here are some screen pictues I took.

All help is highly appreciated!


Thanks,

Matt

test your OC with Prime95 can see stable or not

 

[jaguarmatt]

It's stable. I can put the voltage down to 1.295 and it's still pretty stable.

 

[Achilles295]

Start increasing your cpu's clock by 5-10MHz at a time and then testing for stability. When you hit a wall, try upping the voltage by 0.5v and continuing. When you reach a level that you're satisfied with, let Prime95 run for 10-12 hours.

I hope you meant 0.05v =]

Currently at 3.52ghz with 1.325V, temps maxed out around 58c. (All cores at 100% with NO case airflow)
Hoping my new fans will let me bump up the speed a bit, however 3.5ghz is definately a nice increase from 2.8ghz.

 

[Achilles295]

Yes that's what I meant.

The temps are really good especially without airflow in your case.

 

[jaguarmatt]

I added 2 fans (80mm Dynex and 82mm Foxconn) and the temps went down about 4C.

Really don't know where to start overclocking from here lol.
Is 3.5GHZ good enough for gaming (1920x1080)? That's pretty much all this computer does.

Not really sure how you got to where you are - it looks pretty good, BUT I think you can do it much better a different way.

Your RAMs are running 1640MHz. You need to drop the memory ratio from 667 to 533 to correct this issue. You also need to drop the HT multiplier to '8' (or the 1600MHz setting) - a 2460MHz HT link gives you nothing from a performance standpoint and lends to higher temps and instability.

Once you have dropped the memory ratio to 533, 14x250MHz will return your RAMs speed to stock spec (5.33x250) 1333MHz. It is advisable to bump the NB volts to 1.25v at IMC/NB 2500MHz.

AND clearly your RAMs can take a nice OC so the system clock at 260MHz+ is not out of the question. I would suggest dropping back the IMC/NB multiplier if you want to see how high it will go - you can always work it back up.

Same goes for your memory - drop the ratio to 400.

That way, when you run 13x300MHz, it won't hold you back.

Before I do this, would it matter that the ram doesn't have any heatspread? Infact, it has extremely small heatblocks compared to other ram that I usually get.

I got to 3.5ghz by using a 15% overclock, then 10% of that. (It's installed on my board; only thing I had to change was cpu voltage)

Best I can tell your RAMs are now running overclocked at 1640MHz. Making the changes I suggested and they will be running at stock specifications. At the 533 setting, DDR3 will run 1333MHz with the system clock at 250MHz.

These would be changes to the settings in the system BIOS. I cannot help you with your utility.
