Laptop overclocking adventures

[theonetruewill]

sweet good job man. as far as the OC do what the will said, but it may be it's getting to hot, or needs more voltage, and yes you are overclocking your ram, so that may be your limiting factor. as far as the x700 have you tried to make your fan in your laptop spin at max speed? i know that makes or breaks my gfx when i oc it (freezing/not freezing). as far as the 3d mark score, it may be because the cpu is overheating and it has to throttle back to save itself from dying. one more thing...how are the temperatures at load?

@ theonetruewill: you never told me about cpu burn in....i might just have to do that so i can drop the 12x multi to .95 (i hate how the voltage options stop there..)

Yes, I really should have included that in the guide. Good Point.

An Moto, I believe the Chang man may be right on his hypothesis. You're RAM is most likely your limiting factor if you can't get over 1.92Ghz regardless of voltage. I feel for you There are several ways to deal with this....and neither of them are particulalry pleasant. Number 1- get some "better" (normally meaning more expensive RAM- I recommend Crucial) or flash your RAM's SPD (the instructions it has to tell the motherboard at what speed and latency timings it runs at) so that the latency timings are a little looser.

For example: My DDR2 currently runs @ 4.4.4.12 @533 (default) However I too believe them to be my limiting factor as I'm sure my CPU can reach above 2.25Ghz(that's it's total MAX!). However changing the SPD to loosen the timings to 5.5.5.15 may give me a higher overclock. Now this isn't as easy as I make out. TPU's very own SPD Flash tool can do two things to your memory.
1. It changes it and it works perfectly!
2. Your RAM is f*cked and you're f*cked

So those are the two solutions- but do me a favour; humour me and try @ Max voltage with the burn-in tactic.

at load:-

- OCed to 1.92GHz @ 1.356V........70C-71C (anything above 1.92GHz causes a freeze)
- OCed to 1.92GHz @ 1.212V.......62C-65C
- 1.86GHz @ 1.212V...................55C-60C

Quite frankly, i have no clue how to program ACPI script for use in NHC so i am relying on Acer's ePower management and eManager to control fan speeds and turning on/off various hardware components such as wireless/bluetooth/cardbus/firewire etc. I've selected for the laptop fans to be constantly on via eManager. Tried Speedfan but it couldnt detect my fan settings etc.

Essentially, I've got an Antec notebook cooler pad working its magic on the underside on my laptop, an Evercool NB-MA1 USB 3800RPM extraction fan (awesome little gadget!) augmenting the air flow within the laptop and the laptop's own fans constantly being on (although i have no idea at what RPM they are spinning at nor if there are any compatible programs that allow for manual RPM selection).

have you tried oc about 1.92 ghz at one step above 1.212 (at 1.356 you may be too hot). umm that and your memory may be oc to the max (did you check the unlink pci or w/e it is in clockgen?) oh and how are the gfx temps? ps, moto what is your ram...and what are the timings, etc. also, can you tell us what your fsb is? it would be helpful if you just posted screenshots of cpu-z of these things so we can see what you are running on your laptops.

Oh crap forgot about the gfx card completely. Forget 3D06- it is incredibly biased towards Shader Model 3 enabled cards, and I personally don't trust it. For example I got 4309 with my 7600GT, but I only get 5557 with my X1900GT and that is far better (up to 40% in REAL games)

3D03 is a better comparison. And damn you! I envy your gfx as well! I have the X600se chip that in fact only has a 64bit memory bus instead of the X600's usual 128bit, resulting in half the memory trasfer rate- and that's why I have to overclock it so insanely

ughh i know i only have a 64 bit bus to, it sucks. i wish i had a x700 too, it's fast (compared to the x1400, but yeah i do make it work)

That's the spirit old friend! If this guy needs any more help I'll leave him in your hands. I'm tired (it's 2:35am ...again) and I've got to go an set up a home network and printer system tomorrow @ 9:00am........sh*t oh well, more money for me....zzzzZZZZZZZzzzzz

zzzZZZzzz...I wonder if anyone has noticed that the methods in the guide are all given titles from films......zzzZZZzzz...sorry what.....zzzZZZzzz

lol lucky, you have a tech sorta job. i work at fast food...oh man i have to get up a 9 tomorrow anyways.. good luck with your network set up.

after further fiddling, i've managed to further undervolt & OC my CPU. GPU also been OCed some more as well:-

Pentium M 750: 1.86GHz OCed to stable 1.93GHz from previous 1.92GHz and undervolted more to 0.716V @ 6x and 1.100V @ 14x. Temperatures reach a maximum of 65C when OCed at 1.93Ghz @ 1.100V under load. Idle temperatures are 47C-48C.

Mobility X700: further OCed core and memory - 358@413 and 345@385 respectively. Seems stable enough, no artifacts though i'll probably need to run some more tests.

Currently using SP2004 for stability checks and OCCT for cpu burn-in although i am not too sure if OCCT is a "dedicated" burn-in program as opposed to another alternative to SP2004. I'm going to give OCing my CPU to onetruewill's "holy grail" of 2.2GHz another shot. Hopefully, this cpu burn-in stuff should improve things some more.

Well done mate. You're getting there- use burnmax in conjunction with orthos (run burnmax @ idle though). I think I might have a leaderboard on the first page- so you'll be on it.

 

[Hello_Moto]

when i first ran burnmax in conjunction with SP2004, i set it to high. Everything slowed down to a crawl and my laptop soon became unresponsive....I thought to myself "screw that!" and used OCCT as an alternative after a bit of searching on Google.

I'll try again @ idle. Cheers for the tip.

Over 1000 posts , sorry just had to announce it somewhere.

 

[Hello_Moto]

lol only 995 more posts before i can do the same.

Just an update: after some playing around, managed to undervolt my Pentium M 750 even further down to the bare minimum that NHC allows - 0.7V @ 6x - and 1.068V @ 14x. anything below that causes system instability when tested with OCCT.

Cant seem to stably overclock >1.93GHz even @ 1.356V. Managed to get a decent enough score (IMO) of 6818 when everything was OCed.

sweet score man. i get like 3k . nice undervolting to i just wish they unlock the bottom voltages for core 2 (lowest is .95....stock for 6x...)

OK this is going to piss you off My 750 doesn't even run at 1.356v like most of the other PM750's. Mine is the more eco-friendly 1.308v version!! So I'm getting a higher oc at a much lower voltage- that is blatantly unfair in so many ways!

wtf?! that's like rubbing salt in the wound lol.

I recently updated my bios on my acer aspire 1693 and now the tweaked voltages (0.7V and 1.068V respectively) cause system instability....random freezing aplenty!! I'll have to increase them again: 0.716V and 1.084V seem to be doing ok for the time being. Weird.

My DDR-PC2700 RAM is manufactured by Micron Tech. Are they a reputable company or one of those cheap generic manufacturers? Just wondering if perhaps changing my RAM for something better (been eyeing some Samsung Branded RAM on eBay) could allow for an overclock >1.93GHz.

Damn you and your 2.2GHz overclock!!

Micron make the best RAM chips in the business- the Micron D9's. Leave it. You're problem is probably the fact that you're running off DDR, not DDR2. I have Hyundai RAM

Yup, I apparently have one of the most overclockable x1400's on the market.

You kno what's a real bummer? My X600se is being rated against normal X600 mobility cards. Surprise surprise it's not on top. I want to see what kind of points I'd get if they made an X600se an option in the gfx card menu

lol, isn't se the not so good version? But you got to admit, for an x1400 mine has a nice oc (stock 432 core, 391.5 vram)

Edit: check it, TPU is 69 right now.....more people need to join.

It does clock well! The SE uses a 64bit memory interface instead of the usual 128bit (SE chips always use halved usual memory bus controllers bandwidth). This means I'd have to clock the core at twice the speed (half way there) to achieve the same raw memory transfer rate. And yes more people need to join.

Ahh, but I think with our cards it's not so much memory bandwidth limitations but the fact that our core's don't have enough processing thingys (w/e they are). Although I must admit, more bandwidth would be better...(btw x1400 only has 64bit memory interface too, I think). Holy $hit, I just released my pos Hyundai memory has more bandwidth at 553mhz then my memory at 882 (ddr). Dual channel.....128 bit interface.....pos x1400 (I want a 8600 gt now....lol)

Vertex shaders, pixel pipelines, ROP's, Shaders, etc take your pic We're f*cked with our cards
Hyundai should just make RAM imo. They're good at it.
