Overclocking laptop

Is there a way i can overclock my gateway t6815? what software can i use since bios doesnt have option for laptops to overclock? My specs are here, i think you would agree the cpu needs to be faster?

14.1" gateway t-6815
santa rosa chipset
centrino duo t5250( 1.5ghz, 2mb l2 cache, 667 FSB )
intel x3100 GPU
G.Skill 2gb ddr2 667mhz cl4 RAM
160gb 5400rpm hd
Vista 32bit

 

You can't OC the CPU. And that is a good CPU, even if it is 1,5GHz

 

so the specs for my laptop are pretty good? I will use it for very light older gaming and just school work like word, internet, visual basic, java programming, research, etc.

That's very broad, and often times wrong. CPUs can very easily be OCed even on notebooks, it's just a matter of compatibility. If the software available (clockgen or setfsb) supports his specific motherboard, then he in fact can OC his cpu.

 

adinu is correct, but with the tasks mentioned I would start without OCing and see how it works I don't think you will need to OC.

 

ok im trying to oc using clockgen and when i apply the overclock it just goes back to normal speeds, wont OC. Also setfsb just freezed my comp no matter what i do, even when i underclock it, i just want it to hit 1.7ghz, any help?

 

Which is why I said that you can't OC. I wasn't talking in general terms, I was talking to you specifically. The Intel Laptop chipsets don't seem to be able to OC.

 

Which chipset did you select? Fab you are wrong Bud.

 

On what grounds?

 

Wrong or not, overclocking a laptop is inadvisable for a number of reasons. One, it voids any warranty on the machine. Two, you risk frying the CPU and potentially damaging surrounding internal components. Three, the machine will be prone to overheating and instability. Fourth, overclocking a Core 2 Duo is pointless; don't go off thinking that clock speed dictates performance nowadays, because your CPU can humiliate a 3GHz Pentium 4 any day. Anyway, I wouldn't recommend it; it's like trying to pimp out a Volkswagen Beetle: it just doesn't work.

 

the chipset is the intel express GM965, "santa rosa"

 

It can't be overclocked. If you were interested in overclocking your notebook you would have researched and bought one that was capable...or possibly just been lucky enough to have one. And contrary to what some people say it's possible to have a stable overclocked lappy that runs cooler and faster than stock. Think thermal paste, lapped heatsink, and undervolting.

 

I agree fully. If you desire more performance, save the money and upgrade the chip although that may void your warranty also. Overclocking a laptop is never a good idea. The thermal thresholds for the chassis are typically very stringent and stretched for the most part already. Besides bumping clock speed as said before is no guarantee of performance increase.Try uninstalling unnecessary processes in your OS or increasing your memory.

 

Yes, there are other ways to improve performance that aren't as dangerous to your warranty as OC'ing. But if you were worried about your warranty I don't think you'd ask. About the whole thermal threshold thing...some people are just ignorant. Raising clock speed doesn't automatically equal higher temps.

 

Actually it does, but until you begin raising clock speed in large amounts or increasing voltage you're not going to see huge increases.

 

well I agree with bc135 completely.........notebooks arent desktops, its much harder to regulate temp, and if something does go wrong, replacement parts arent easy to come by

but you can definately pimp out a beetle, ive seen some nice ones that are classicly pimped, just refined and fast

 

ALL C2D's are fast enough to run the most common & more advanced apps.
They all have plenty power also.

 

Exactly my feeling about it.

My cpu came stock at 1.6GHz and 1.075 volts. It was idling at around 47-49 and maxing out in the low 70s.

I since undervolted it to 0.975 volts and OCed it to 1.8GHz. Now it's idling in the high 30s and maxing out at 64.

So how can anyone tell me that OCing is bad and will overheat and kill my system when it's running less volts and a lot cooler than stock?

 

If you don't raise the voltage you won't see temp change beyond the processors normal day to day variance. Also you don't "have to" raise the voltage to see "huge increases"

Examples from my experience:

I overclocked my laptop from 1.6 to 2.13GHz a 33% overclock without rasing the temp. Then I went ahead and undervolted it and did a full stability test. It idles at 33°C and at full load tops out at just 50°C.

On my desktop (Pentium M speedstep enabled) I overclocked it from 1.5 to 2.4GHz a 37% overclock without raising the temp. Then I went ahead and undervolted it and did a full stability test. It idles at 28°C and full load it's 45°C with an incredibly tiny heatsink.

If I lock the processor at the lowest multiplyer (960MHz) it can run full load at 35°C with only passive cooling. That's no system fans whatsoever. Very handy for dling torrents overnight and keeping the electric bill down.

so what's your experience?

 

Your laptop uses a heatpipe based heatsink which means that the heatpipes will transfer heat at a greater rate as thermal energy increases, thus minimal power increases to the system will result in seemingly little or no heat increases until you reach the saturation point of either the heatpipe or the heatsink it takes the thermal energy to.

Given that clock speed increases result in very small increases in thermal dissipation (depending on increase amount) you will see very little to no increases in temerature depending on the setup (heatpipe vs traditional heatsink, processor (t-bred A vs t-bred B). The relationship is purely linear in this setup. When adding voltage to the mix temperatures will rise dramatically due to clock speed increases beyond what you also attained using stock voltage.

My experience?

Currently I own an Alienware M5750 with a Merom T7400ES (B2) which is running at 62c loaded with about 23c room ambient. CPU load is provided by World Community Grid using the BOINC agent which results in real world load of about 90%. Using Intel Thermal Analysis Tool I can further push the CPU to nearly 75c loaded... This is at 1.125v as well, which is undervolted from stock settings. I have not been able to find the PLL on the motherboard to attempt overclocking and the information does not appear to be able to be found on the web.

My second laptop is an older Compaq Presario 2100 with an Athlon-XP Mobile 2400+. I should hook the temperature probe up to it and see what temperature it is running at... i've never bothered to find the PLL on the motherboard to overclock it had problems using software to try and control voltages, so I never pushed on it.

My current running desktop is a Supermicro X7DAL-E with 2x Xeon 5120ES cpu's running at 2.33ghz with a BSEL modification (266mhz stock, 333mhz modded). Stock frequency is 1.6ghz iirc. I have pushed them to 2.8ghz on stock voltage and would go more, but either the controller chip on the FB-DIMM's is holding me from going over 400mhz or something else is. They load around 65c.

Other cpu's I have hanging around in my inventory are:
E4300, A64 2800+, Celeron 326, 2x Athlon-XP 2500+ Mobile, 3x Duron 1100, Duron 1000.

The E4300 I pushed to the limit of the motherboard I was using (Asrock 775Dual-VSTA, ~300mhz), the Celeron 326 did 4ghz on that board as well, have not touched the 2800+ yet (old one did 2.4ghz @ 1.75v on different mobo than I have now), the XP 2500+ mobiles each were pushed to 2.7ghz at 2.0v+ on air cooling (one ran for about a year there until I went A64), and the Durons I purchased from a friend with the intent to push 3.0v+ into them when I get around to it...

I've had numerous other experiences with everything since the P1 233mmx (my first CPU, its still running upstairs in an Aopen AP5T-3.1 at 250mhz on stock volts) but thats a rather long list and if i'm going to do that I may as well start dropping in video cards too.. if you really want to dig that deep you can search my username over at xtremesystems.org in the forums, but you'll have to do it manually I think as the search function wont go deeper than the the last 500 posts and i've got over 12,000 posts there.. so it'll take a while.


Oh, and if speedstep is enabled on the Pentium M setup, you dont need to lock the multiplier when its idling..

 

No it doesn't.

Yes but you do need to lock the multiplier when you want to check 100% load on the lowest multiplier setting ...which is what I said i did.

Maybe you got confused about the "dling torrents" thing... that's downloading torrents, not idling.

That's a good amount of useful experience you have but you need to share only correct knowledge if you really are interested in helping people. If the rest of your 12,500 posts have the accuracy you've displayed here then they're certainly not worth researching.

 

Sorry, I assumed your laptop to use a CoreDuo/Core2Duo CPU rather than a Pentium-M which runs much cooler and will experience even less increases in thermal dissipation due to only having a single core.

Anyways, you cannot get away from increases in thermal output when increasing clock speed or voltage.

My XP-2400+ idled just fine while downloading torrents, 596mhz.


Anywhere else you feel I was incorrect?

 

i bought a t-6815 and i want to install win xp just i can not find any drivers. please help!!!
