setFSB - tool to OC your notebook cpu!

I just OC'd my T9300 peryn to 3.1ghz (from 2.5ghz) and after verifying via orthos, it is running fully stable at this speed. Memory was also OC'd using this tool and it is currently running at 414.7mhz (from 333mhz).

All I can say is wow.

Many of you are probably aware of this program but, for those that don't know, here it is:

My windows experience index just jumped to 5.4. Not bad for a 14inch notebook with processor and memory scoring 5.6 and 5.9 respectively.

I recommend using RMClock to disable all other FSB multipliers except the highest (in my case x12) and set to the highest VID of your cpu when using this tool.

The link is for the undervolting tutorial using RMClock but you can use RMClock just to disable multipliers as well.

Probably a good idea to make sure your notebook is plugged in, too.

You quoted him the same thread he's quoting in this post.

 

ugh. repost?

 

Am I late to the party? lol.

I did state that most of you would already know. It's for those that have no idea how fantastic this program is.

 

A brief, but very important note. Use overclocking only if you really need it. Few people really need full 100% CPU speed of the newer CPUs, as it is. Never do it just to increase benchmark scores (they are not an end goal in themselves).

Most games do not top the CPU, but the GPU.

Pretty much no regular office work application tops the CPU.

This might however be useful for CPU-intensive stuff like video encoding, rendering, mathematical simulations.

 

I like the "feel" of OC'd system. The system feels more responsive due to the over clock.

The best thing about the OC to 3.1ghz is that it is fully stable at stock voltage (1.1375v). No voltage was increased (can't do it even if I wanted to due to the limitation of the bios) but I gained 600mhz! Heat is not an issue as well. CPU is currently sitting idle at 37c.

For battery usage, I use RMClock and run the system at 2.2ghz @ 11x multi which only requires .950v.

 

Id rather find a way to change my cpu multi in the G50 from 9 to 10 as the cpu supports it, when you directly up the FSB you induce overclocking the ram and things too so more chances for a problem. Still I will give this a good look.

Clockgen does not work on the G50 so maybe this will.

 

Yeah, the setFSB increases the RAM speed when you raise the FSB. Took mine from 667mhz to 830mhz. Not having any issues at these new speeds though. Orthos benched for 1 hour then gamed for 3 hours straight with no issues.

My notebook has been on for 10 hours since the new OC and so far so good. Will keep it on 24 hours to see if there's any issues.

 

Before and after Everest Ultimate numbers.

 

I would still recommend never using the CPU at full blast all the time, but using a dynamic profile that includes the lowest multiplier. Even if the temps are low, why not keep them even lower? I have never experienced any apparent slowdown due to RMClock changing the profiles; so I do not see a benefit of forcing the CPU to run full-speed. Maybe I'm just not sensitive enough, who knows.

Also, I don't really care much about numbers But if the system feels indeed more responsive, then fine, why not. You could try using the OC highest multiplier, and then the lowest multiplier also on OC, so still making use of dynamic switching. (I'm not sure if it's possible to do this)

For battery profile, you should probably use the minimum multiplier, not 11x. That's because 11x at .950V eats more power (Watts), and heats up more than 6x at .950V, even though the voltage is the same. (it's not something that I'm sure about but it's pretty likely)

 

I only plan on running the system at full blast when it's plugged in. I don't plan on running the system constantly at this speed though (or maybe I will, lol, just for kicks). Right now, I'm keeping the system running at this speed to ensure it is 100% stable. So far after 20 hours of at this speed (good chunk of it stress testing), is it still fully stable.

And yes, using RMclock, you can switch from the highest multi to the lowest. I plan on using this setup for battery usage or just use the lowest multi depending on how long the battery lasts. But I would think the difference would be nominal but further testing needs to be done.

 

What I mean is always use a dynamic switching plan, never push the CPU at full blast all the time because it is unnecessary.

(this does not apply to the stresstesting phase of course)

Yeah, I think dynamic switching on battery won't hit the battery life too much, in comparison to just capping the CPU freq at its lowest.

 

Hi there guys, I have read how mechguy OC'ed his CPU and I am impressed by the great improvement on his system. I could use some assistance in OC'ing my gateway p7805u CPU and since I have no experience and little knowledge on how to do this, I would like to know how you OC'ed your system in a simple step by step procedure. I have already read the http://forum.notebookreview.com/showthread.php?t=249470 but my processor is a P8400 and I didn't see it listed there. Can I still use Auto setFSB? Just to let you know I have no access CPU settings on BIOS. Greatly appreciate help from anyone who can.

 

There are two programs you can use SetFSB and Clockgen. I prefer clockgen as it is a much simpler, cleaner interface. What you need to do first is look up what PLL number your p7805u uses. A google search might pick that up for you or someone can chip in with it. Then you simply select the correct PLL from drop down box once in the program and click the read clocks button. Then you are free to up the fsb(front side bus) in small increments clicking apply each time till you reach the limit.

You will need Orthos to stress test the CPU at each new clockspeed and HWMonitor to check the temps of the CPU in realtime. Also having CPUz is also a good idea to double check that your overclock is working properly.
If your computer restarts/freezes or the stress test program stops itself then your new clockspeed is not stable. Make sure your CPU NEVER goes above 80C.

Thats a crash course in overclocking your CPU. Note not all laptops support a valid working PLL number in these programs meaning you can't OC. Also as EBE stated on here some time ago there isn't much reason for OCing your CPU unless you run CPU intensive programs such as photoshop etc. Games even intensive ones will not benefit from a higher OC on modern processors. I experienced that when I took my processor from 2.93 to 3.25ghz and there is practically no performance increase even in Crysis.

Hope this helps

 

How you change multi in the G50 from 9 to 10?

 

I think the thread is so old that since he posted he has got a W90. Still he may still have the info.

 

Really? There is no performance increase to be expected in OCing my core duo p8400 to 3.2ghz in games like GTA IV?

 

In GTA IV you should notice a difference since it is highly CPU dependent. But most games that are GPU bound will show little to no improvement.

 

It was a fluke, I still have the screenshot somewhere but at random I saw the cpu multi fluctuate to x10 so I know it was physically possible but never did find a way to do it on demand.

But yeah I have a W90 now with a Q9000 and with setfsb it overclocks to a nice 2.7ghz so I have nearly double the cpu power now that I had before.

I was encoding some anime episodes last night for my cell phone and I tell you its quite a treat to have that quad core when doing work like that.
