Cheap Processor Upgrade? - Page 24

Has anyone made a nice socket diagram with the voltage pins and what to do all circled? I'd like to see that .

I plan on making one. I'll write it up during my 23rd hour of prime. Although intel's white paper is more than sufficient. They have all the vid pins grouped together diagonally with grounds above and below them.

Also do a search in the forum for "photo guide" and the photo guide for pinmodding will come up, that helps a lot for the bsel0 pin

this processes seems like a lot to me

you guys really gained anything after all, any 3dmark05 improvements ?

I turned a Pentium M 715 into a 760 for under an hour's work. Dell charges 350 for the processor upgrade.

It causes an improvement in the processor score in 3DMark05 but little in the graphic score.

SirBA, to some of us, this IS the game, the benchmark, etc. Of course it won't help much for modern games, as they are GPU limited. I ran a doom3 timedemo at 1.86 and at 2.66 (to compare what I started with to what I have now), and got 40fps both times. Most of the time I am limited by my 4200rpm HDD when I am not gaming. I never do any hardcore number crunching. I don't really NEED to calculate one million digits of pi in 31 seconds. But for those who are pushing the limits of the equipment like myself, it's more of the issue of knowing you can do it

Besides, rp3 is right, you can buy a cheap chip and turn it into a more expensive chip. Hell, if dell offered 2.66ghz chips, imagine what they would charge for them if right now they are charging $400 to go from a 2.0 to a 2.13. And people are paying it!

3dmark03 and 05 are designed to put as much load on the GPU as possible. You won't see a difference by changing CPUs unless it's is a extreme change.

Question for those who opened up their XPS gen 2 -
Is the heatsink for the CPU made up of copper or aluminum? I was looking at the xps2 service manual and the picture on THG (http://www.tomshardware.com/mobile/2...ll_xps-04.html) and they both appear to show aluminum heatsinks with copper heatpipes. I'll order a new heatsink from dell parts if it is copper, but I want to make sure first.

I have discovered the processor does NOT thermal throttle at the temps I am working with. I heated the processor up to 80 C and ran superpi on top of prime, still pulled off a 32 second 1M.

An update on my 2.66 progress -

Since I haven't been having the best of luck guessing what voltage to use, I started systematically plugging in voltages, running the prime blend test, measuring cpu temp vs running time vs where prime fails, and trying to figure out exactly what the best value to go with is. Here are my results so far-

1.644v - blend test stable 1 hr 15 mins. failed at 12k FFT size. 12k FFT stable for 8 mins before crash. Max temp 77 C.

1.660v - blend test stable 48 mins. failed at 896k FFT. 896k fft stable for an hour... max temp 81 C.

1.628v - ran prime blend stable overnight @ 70 C. Then I put the keyboard back on, temps shot back up to 73, prime failed on 8k fft size in short order. (this occurred before I decided to do a detailed log of exactly what happened, how long prime failed from idle temps, etc...)

Plan on decreasing voltage further and seeing what happens. If anyone has any bright ideas, please let me know

Lucid, ok these ideas may sound a bit crazy, so lets just pretend we're thinking out-of-the-box for the moment.

Have you considered trying to replace either of the fans inside? It may be possible if you can find a small enough slot fan, and mod it to fit in the existing place.

Or, and this is TOTALLY impractical (out-of-the-box, remember ), you might be able to mod the battery compartment. You could place a small modded slot fan underneath the keyboard (there seems to be room), and cut a small square part out of the battery compartment plastic. The fan would blow air out into the empty battery compartment. Then you would just make sure to not have the battery in when you're running at that speed. If you feel like being mobile, simply clock down the cpu/gpu and put the battery in.

Does that make any sense? No, of course not, but I'm just trying to get you to think of a possible alternative to getting the CPU stable at that speed.

Oh yes... the hardcore overclockers have arrived.

I'm trying to find a micro-water cooling system (I hear NEC makes a good one), I've always wanted a water-cooled laptop. Now I actually have a reason to get one.
And they called me mad when, for no reason whatsoever, I water cooled my Dreamcast.

...SNIP

The CPU heatsink IS aluminum with a copper heatpipe. The GPU is Copper all the way.

Alright I have decided to "settle" for a 2.53

I tried every value and vid mod configuration up to 1.692v, here's what happened:

At everything below 1.644, prime fails the small FFT's before things even heat up. The closest I could get is 1.644, where the only thing prime ever fails is the 12k FFT setting. It can do 10k, it can do 14k, but it can't do 12k. Anything over that (1.660+) and the large FFTs fail instead. When I crank the voltage up above 1.676, the system seems stable enough, prime never fails, until about an hour and a half when the system COMPLETELY stops responding. The fans are still on high, still blowing out hot air, but the system does NOTHING. soooo, I figured that's probably too much heat. 83C does seem pretty hot

I didn't feel too bad about missing my goal when I started testing for real-world stability at 2.66. The system couldn't be more stable. However, the temp shot up right away whenever I started doing resizing or whatever in photoshop, and in the couple seconds it took to hit 70C, the fan kicked on high. Whenever I let go, the fan kicked off. Believe me, it is annoying as hell.

When I scaled back to 2.53, I also dropped my voltage to 1.516. At this voltage my CPU temp never exceeds 65C and my fans never kick on high. I do have to have RMClock running to do this, though.

Overall, I would call this experement a success. I do, after all, have the fastest laptop in the world, even at 2.53 :P

Oh and if anyone cares to read my post over at xtremesystems, I posted a picture of my socket with the four pin mods, as well as an intel datasheet overlay showing what pins correspond with what wires. Pretty good stuff: http://www.xtremesystems.org/forums/...ad.php?t=63514

I won't be making any more effort towards stabilizing this at the full speed since even if I did it it would bee too damn loud

LOL, right on man, I can just see the next thread: 9300 6k club

Or a laptop with a 25 sec superpi

Fans

I have been thinking about that too. To replace the fans would be possible, a fan for a hot desktop gpu would be good. Cutting in the 9300 is a bit hard, mine is made of some metal, looks like it not, but it is.

Probably a mangesium alloy. It's super light, looks/feels like plastic, but is much stronger and doesn't scratch super easy. I used to have a Sony Vaio V505DX subnote which had a case made entirely out of the stuff. Felt very sturdy and didn't scratch very easily.

Maybe it'll burst into flames and your whole note will disintegrate in 15 seconds?

has anyone tried changing the sw3 jumper setting? it switches from 400 to 533 fsb

are the small strands that make up speaker wire small enough for pinmodding? (i have some extra speaker wire lying around) ive overclocked before on my last 2 desktops but its always been through software/bios.

Almost all stranded wire is small enough. Usually heavy gauge stranded wire just has more strands, not bigger strands. Just don't try solid core

k thanks, im thinking of trying out the 1.7 and seeing how that goes. i'll keep you guys updated, im prob gonna buy one within a week

Hi, new to the forums. I just wanted to let you guys know that I just pinmodded my 9300 to 2.13 with no problems, and I suggest everyone else do the same (or better). I only have one thing to stress...TIGHTEN DOWN THE BOLT TO THE CPU! I forgot and thought I fried the CPU when it would just shut off after 5 seconds. Now it works like an XPS2, or should I say a champ. Thanks to all the people who have been posting on here and showing me this great upgrade. I bought the CPU off ebay for 100.00 BUY IT NOW.
