CPU/NB and HTT, worth overclocking?

post #1 of 10
Thread Starter 
In a normal day setting, where you have a computer with only one processor and one graphics card, is it honestly worth it in any way to overclock the NB/HT frequencies?

If so, how long do you run (insert stress test program here) to determine its stability, knowing that your cpu/ram are both 100% stable at the current clocks, just upping the multiplier for NB/HT.

My current stable settings are as follows
-CPU : 3750mhz @ 1.3375v (LLC)
-CPUNB : 2000mhz @ 1.1000v (LLC)
-HTT : 2000mhz @ 1.2000v

Using 15x250 at the moment, and those settings above are 100% stable through linpack and prime 95.

Is it worth say.. upping the multipliers a little bit and trying 2250mhz or 2500mhz on the CPU-NB or HTT?

Yeah I would just keep the clock you have now, anyway any overclock from there won't really increase performance a great deal plus its stable so thats an achievement smile.gif

Get that CPU NB as high as you can. 3 GHz is a sweet spot. Most people don't overclock it and cry about bad performance. Phenoms love CPU NB at 3 GHz.

Leave the HTT near 2000. 2000-2200 is fine. Over that, you get less performance and it can ause instability.

Phenoms do very nicely with the NB around 3k. Mines at 3000 personally.
HT Link OC'ing can cause instability, but you can see some performance gains up to around 2.2-2.4k. 2-2.2k is the sweet spot for that really.

OC that CPU/NB. Dont think it will help? Grab MaxxMEM and see for yourself. Then OC your RAM and you'll really smile. biggrin.gif

Leave the HTT alone though. 2GHz is where it needs to be.

Thanks for all of the input you guys, much appreciated. smile.gif Mad +Rep coming as soon as my PC is done priming, can't stand mousing with this netbook.

Since I have a non-BE chip, multi's are locked, so currently using my maximum CPUNB multi of x10, running for stability at 2.5GHz NB @ 1.1v, so far so good, knock on wood.

HTT was left at 2Ghz as recommended.

Also, I'm somewhat afraid to OC my RAM heh, Im not even using it at its rated speed of 1600, board set it to 1333 @ 1.55v, next strap up will put it to 1667.

CPU/NB @ 1.1v will probably do just fine with the underclocked RAM. Thats where I was until I pushed the RAM, ended up @ 1.2v CPU/NB. thumb.gif

I highly recommend using your RAM to its full potential, and then some. It's what you paid for, you know? 67MHz over stock is hardly an OC, more like a technicality. wink.gif

And since you left the RAM on Auto, make sure the timings are correct as well. Lower timings do result in tangible performance!

Good luck!

Thanks Baskt, just a bad, bad experience with overclocking ram in the past. Killed an old Athlon X2 6400 BE, which at the time, I loved a lot.

That was my first attempt at AMD and Ive been FAR more careful this time around, like honestly thinking about dropping my OC back to 3500 instead of 3750, just because it runs a little cooler (takes a lot less volts at 3500). And so far, its only peaked at 56C running Prime95, at the CPU Socket temp, generally holds a steady 55, constantly.

this is what really sold me on cpu-nb overclocking. if anand has something enlightening to say about anything amd, it must be true.

CPU/NB @ 2500 is fine for the memory speed of 1667.
