Undervolting M1530 (T9300) - Worse performance?

Hello, I have been reading some guides to undervolt the processor, so it would consume less power and the fan would make less noise.

Has anyone done it with T9300 and M1530? Any advice? Does it affect the general performance of the system? Does it affect gaming??

Thanks

 

I don't have an M1530 or a T9300 but I can tell you that undervolting in no way, shape, or form affects performance or gaming UNLESS you undervolt it TOO much in which case the computer will hang or crash. All it does is make the CPU run a little bit cooler and saves a bit of battery life. I undervolted my Vaio with NHC (Notebook Hardware Control). Not sure if it works with Dell computers though. I really do recommend it though. It doesn't affect heat too much when the CPU is under load, it still gets pretty scorching, but idle for idle and easier tasks, it lowers the CPU temp by a few degrees.

 

Ther's a guide of it in forum.It should work on all new processors.

 

Wheres the URL of the guide? I've never undervolted before, but would like to try.

 

Here is the undervolting guide by Flipfire:

Undervolting is a great way to reduce heat output without sacrificing performance.

 

I'm undervolting with a T9500 right now. I got my max multiplier to be about 1.0125 volts. You should expect something in that range, or maybe lower. Good luck!

 

Thanks. Anyone did it with T9300?

 

You will get slightly worse performance because of the max multiplier being 12x rather than 12.5x so you get 2.4Ghz rather than 2.5Ghz.

 

yes it works fine with no adverse effects (as long as you dont undervolt it excessively - but even then, it will just restart with no long term damage)

i'd like to add a bit to the undervolting guide kdawgca linked you above. this is coming strictly from my experience and will help you stablize your undervolts and help you achieve a lower undervolt.

1) set the FID/VID transition time to 50us (or a bit higher) - this allows time for the processor to stablize before changing VID
2) set the p-state transition method to "perform single step transition only" - this makes sure that the transition between different FID/VID's will not change so significantly that it destablizes your computer

goodlucK!

 

yeah hes right. RMclock doesnt fully support Penryns as of yet.

RMclock wont read the half assed 12.5x multiplier. It will either read it as a whole number (12,13x)

The only way to avoid this is to set the FSB to 208mhz

 

well, all you have to do is leave the auto-adjust intermediate state VIDs checked and check the 13x multiplier - then the 12.5x works as usual

 

Sorry i dont have a T9300 so i assumed RMclock doesnt see 12.5x or 13x

Isnt 13x the IDA?

Cheers

 

I got 69ºC without undervolting (with stress) and now I Undervolted (or at least I think so, I don't know if I did it correctly , )

 

How much did you undervolt your 9300? I set 12.0x in 1.0125 and max temp has dropped from 69ºC to 60ºC (not too much, I must say).

What else can I do?

 

Anyone can help me undervolting my 9300?

 

Correct, you cannot set 13x on the t9300 without it only using 1 core.

Where can I change the single/multi step option?

 

What does that mean? RMclock doesn't work for our t9300 then?

 

I have a question: if you undervolt, will the "CPU whine" disappear?

 

It "should" AFAIK

 

No, the T9300 has a 12.5x multiplier. RMclock will only read it as 12x which is 2.4ghz.

If your talking about the C4 sleep state "whine" then yes you can toggle those advanced settings in RMclock

You mean locking the clockspeed? not 100% sure on what you meant

 

I don't know what C4 sleep state is, but it's just a sound of electricity when using the laptop ...

Will this have any effect on the performance or life span of the laptop?

 

no effect on performance

it will make the lifespan of your laptop longer due to less heat (which is responsible for killing electronic parts)

 

So if I wanna undervolt T9300 I just have to enable IDA 13x mulitplier, find it's lowest VID and enable "Auto-adjust intermediate state VIDs" ?

 

First, thanks Flipfire for your great guide..

Second: this is how I'm running my T9300, I didn't made a lot of test... (actually I just messed with RMClock like 2 hours) but I can confirm that this set up is very stable for an T9300 in a XPS M1530, I will try to undervolt even more and then I'll post the results in this thread.. (since I didn't saw any stable configuration for a T9300)



Hope this help!...
By the way my lovely processor went down over than 10 Celsius.. thanks again FlipFire!!!

 

lower power consumption, cooler lappy, longer battery life...what more could you ask for.

 

HI!, I'm back!..
here i found a better undervolting for a T9300, I ran Orthos for 45 minutes and my highest temps were 68C!! im very happy, since I use this lappy for gaming and undervolting became a MUST!

 

@terrapirata > Thx so much for both of your screeny. Cause of that, ive decided to undervolt my own T9300

and this is the result


That was my second 'FINAL' test, which i decided to stop halfway through, since it should be 'stable' already. The first final test went for almost 30 minutes.

Pre-undervolt temperature: (Could be higher, since i only ran ORTHOS for 5 minutes)
Core 0: 75'C
Core 1: 79'C

Any comments/opinions/critics/questions welcome

 

Well. I almost sure that you didn't change the thermal paste in your XPS...

because before I had the almost same temps than you without the thermal paste

(thermal paste + undervolting is a cool pleasant combination for a gaming laptop)

I can recommend arctic silver 5 for ours laptops, very cheap (in ebay for 6 bucks) and very easy to install.

EDIT!!:
Ohh i'm sorry, I saw now yours results!!, yeah you are great (i think) for a T9300!

 

awesome find. After reading this thread I undervolted my T8300 and am enjoying much cooler temperatures!

10-15 degrees cooler. I already have artic silver on the heatsink so the combo should hopefully help make the comp on my lap more bearable.

 

here is my for T9500


every FID passed more then hour long test with orthos

and here some temps with Orthos and DX9 Real-Time (with Coollaboratory Liquid Pro paste) :

 

Mine with the original Vista home in power saving mode used to work at 0.92 volts. But after reinstalling xp or vista ultimate ow win7 never saw that low voltage

 

hey guys I undervolted my new sxps 16 t9550 @ 2.66ghz and I can tell you it makes a world different.
Before undervolting under stress test CPU core temp reached 85C. After undervolting setting 1.0625v @ 10x multiplier, the max temp now is 65C. It's 20 degree different guys. And I havent got any BOSD under heavy loads.
My infinite notepal cooler reduces the temp by a further 10C. Must say I'm very pleased with the results so far, heating is no longer an issue !
Hope this helps and encourages everyone to experiment with undervolting because it really kicks !

 

Well it seems there is a whole lot of difference in Windows Vista and Windows 7. Let me tell you guys what happened. Before i was having windows vista and i have done the undervolting. I got the most horrible performance and i was not able to play my games. After few months i simply upgraded my M1530 with Windows 7 because i have heared a lot of buzz about windows 7. Then i thought lets give it a try by undervolting my M1530 in windows 7. You won't believe this but i had totally different volts in RMClock under Windows 7. I have runned some games (i.e Dragon Age and Dirt 2) and i was able play without sacrificing performance. My M1530 is running a lot cooooool even after playing it for 3 hrs. I saw a 10 degree drop in the temperature.

I guess RMclock is one important tool for M1530 and user should have one.
