overclocking hp products

Hi everyone Im trying something new today..
Not much of programmer yet but trying to learn.
I have an hp pavillion that I want to learn all the do's and dont's with
I want to overclock this unit it contains
hp pavillion A317X
2.5 ghz celeron processor
1 1/4 gig ram
intel extreme graphics 64 mb shared memory
windows xp sp2
wireless card by dynex
if you need to know more I'll try to tell you. where do how do I start to overclock?

 

If their are no overclocking settings in the bios your only chance is overclocking via the PLL.

 

Well.... Thank you for responding ace but as usual Im the bearer of bad news my pll was in the wrong list....:mad
so does that mean its over? hope noe I really wanted to learn
I have another comp but I dont think Im ready to clock it yet I just put it togehter.

 

Looks like it, aside from taking a soldering iron to the motherboard or pinmods. TollhouseFrank probably knows more about pinmods and piggy back PLLs then I do.

 

I dont mind doing these kind of mods sound like fun how often is toll house franks on or how do I look him up? Thanks ace.

 

depends on the sorta pinmod you want to do. I haven't personally done one since the Athlon XP days.... and the only one I currently know of that is worth the time and effort is for Pentium M's.

 

Thanks for looking toll house frank it must take some time huh? I think I wouldnt mind still though just for practice and knowledge. Anything learned is earned. as far as to what kind of pin mod dont know because of the first time doing it Im not knowing which pin does what so Im lost there..

 

BBC - that's ok. Pin-Modding lets you do one of 2 things (normally). Unlock the multiplier on your CPU, or Unlock the FSB/Up the FSB Speed.

Unlocking the multiplier died out with the Athlon XP's a few years back. Unlocking FSB/Upping FSB (front side bus) speed is where it's at now. One of the most readily done ones is for most of the current Mobile Pentiums out there. By using a hair-thin wire in the socket between 2 certain pins, you can 'short' them out, and the motherboard reads the cpu at a much higher FSB, thus giving you an instant 33-50% boost in speed, depending upon the model of Pentium M used.

 

now that is what Im talking about I put 1 1/4 gig in this thing and you can barely tell if at all now that sounds like good speed but you say pentium m how diff is that from the celeron??:confused

 

Pentium M is a much more versatile chip than a Celeron, The "M" is designed for mobile computing to extend battery life when usage demands are low and to ramp up cycles when more CPU is needed for multi-tasking. The celeron chip is designed for budget computers and is much less flexible in regard to over-clocking, much like the AMD "Sempron" ; both of these chips were good solutions for computers that were not needing as much firepower so they end up in low end desktops and laptops because they are priced and operate much slower than the premium line of chips.

A person with a new idea is a crank, until the idea succeeds "Mark Twain"

 

Thanks Huntzilla 4 the reply so should I just give up on the hp Then? what about the pin mods that tollhouse franks was describing?

 

I am sure that you could still apply the pin mod. but u won't see the same percent gain that would be possible using a higher grade chip. Your best expectation would only be a slight gain in power (just a guess of 2-10%) on a Celeron chip, my recommendation is to shop around from a reputable dealer on ebay or on this site for a chip that has more mojo, say in the 3.0 to 3.6 ghz range and then you would have no need for an overclock anyway. Celeron is just slower, look for a Pentium-M or a dual-core intel chip(whatever the mobo will support, check the manufacturer's page):confused

 

Celerons are known to be great overclockers as are semprons. :guns Most celerons meet or beat the performance level of there pentium counterparts while overclocking. The only difference between most pentium and celeron CPUs is the amount of L2 cache. The performance hit of having less L2 cache can be overcame by a mere 200Mhz in most cases.

 

So lets take your point up, Celerons may be better overclockers in a home built rig with an open architecture mobo that supports tweaking FSB settings or letting more juice hit the CPU. In this particular case, other than the pin mod, it does not sound as tho the "HP" board can be overclocked without a labor intensive over-ride. Yes I was mis-informed about the potential of the Semprons/Celerons to achieve a decent overclock thanks for setting me straight.

 

Thanks for the replies but honestly..... I was told the same as ace is saying that the celerons are really good overclockers and have alot of unknown potential.... I just wanted to start with my hp for the first before I get power hungry like I do in the garage, and clock the one I built which is going to hapen anyway I just wanted to get some knowledge before I overclock my duo core the nice thing is my mobo supports pretty much anything that I want to over clock so It will be real easy on my part I was out for the practice on the HP but thanks guys looks like Im going to tamper with the duo core unless I can find pin mod info...... either way This is cheaper than building what I'm used to.....

 

Stock is 100(x4 to get FSB data rate) x 25 = 2500Mhz or 2.5Ghz. This should force a FSB of 133 (533 data rate) there by forcing 133 x 25 = 3325 or 3.325Ghz but I cant be 100% as I dont have the time to try it on my test board. Its a bit of a long shot if your CPU will be stable at stock voltages at that speed. Im not sure when I will be able to verify this mod, perhaps Tollhouse can. Try at your own risk.

thanks ace but Im ignant is that a fine wire I see in two of the holes or am I missing what you are saying sorry....

 

Yes a very fine wire that shorts the two pins when the CPU is in the socket.

 

Ill try it the most that happens is I burn it up right Im sure I can find another celeron easily... Thanks ace I ll try it tonight or tomorrow and let you know how it goes the wire to use is what .025'' ?

 

I use the wire out of an old IDE cable. For the most part smaller is better.

 

If my socket is a lttle diff is that ok? I just count the number of holes to duplicate the pic right?

 

That is a pic of a 478m socket for laptops but it is the same layout. I will try to verify the pin mod tomorrow.

 

I tested the mod on a Compaq / HP motherboard with a 2.5Ghz celeron. The system did not boot with the mod, but worked fine when the mod was removed. I also tried the mod on a socket 478m laptop with the same results. I can only assume that the mod works but the CPU's could not take the overclock at stock voltages.

 

it's a 50/50 with his celeron. pentium M's can get wonderful overclocks without raising voltage. to run his celeron at the higher fsb, he can hope for luck, or hope he has a voltage regulator in BIOS that allows him to up socket voltage about 0.025 or 0.05.

 

thanks for the replies I think Im gonna try anyway and let you know how it goes right now pulled the processor and it is really glue to the heatsink and cant get it back in do to the lock cant be in the unlock position due to the heatsink so I have to get some new grease or glue or what ever it is you use to assemble it together again. let you know soon

 

mmm yes what there saying would work but in my experience Celron cpus are not worth over clocking IE is 1.8 P4 is faster then a 2.4 celaron due to the celarons small data cache
on A side note a lot of the cerlons are sensitive to over clocking Your best bet is get a P4 about the same speed IE in the range of 20-30 bucks on ebay and over clock that if you must XD

 

Another celeron basher?rolleyes

ahhh master!

 

Update ? CPUs with large heat spreaders tend to that even with normal paste/grease. The best way I know how to get a CPU off a heatsink is by twisting the CPU from the heatsink.

 

Freeze the sucker. I'm not kidding. Freeze it (if you can get it to 0F* or lower, great). If you have normal silicon goop like most OEM's put on, it'll turn to a nice soft 'play-dough' consistancy at those temps and be much easier to pull off, at least that's in my experience. If you can get it low enough, it'll turn to almost a powder than a tiny bump will lodge loose.

 

Didnt freeze it but close set it out side let the cold temp get to it on the back porch. Worked great just got to get to the store now to get the paste...
