Pentium M 740 on Asus A6R problem II

The above mentioned thread was already closed. Pls refer to the link mentioned below.

May I know if the issue was already solved? If yes pls share it here as I’m also having the same issue with my laptop. Thanks

 

Post up information from CPU-z about CPU, RAM, Chipset.

 

As has already been said, the FSB speed is probably limited to 400 MHz. I had a Dell Inspiron 600m, and I had to use the 400 MHz Pentium Ms (their numbers end in 5, Pentium M 725, for example) when I upgraded from 1.6 GHz (725) to 2.0 GHz (755). I couldn't upgrade to the 770 or 780 because they were FSB 533 MHz processors.

 

OK noted. Is your Dell Inspiron a i915 mobile chipset? If yes a read other thread that you they can overclock the motherboard to run on FSB 533MHz.

 

Sorry I’m novice when it comes to computer and this is my first time to use the CPU-z. I don’t know how to post up here. Can you pls tell me how? Thanks

 

Firstly, what is the model of your laptop?
Second, download CPU-Z through Google search, open CPU-z, click About, and click 'save report' (html or txt) and attach that report to your next post or upload to somewhere like media fire and paste the link into your next post.

 

Asus A6R model with an ATI mobile chipset.

 

I saved report @ html then click the insert link then copy the link in my browser then paste it here... This is what happened :-(

You will probably need to be more specific about which ATi chipset it is as ATi is a company which makes chipsets and video cards, so what you are refering to is half of the products that they produce.

A quick Google search shows nothing much about the Asus A6R supporting Pentium M CPUs with 533Mhz FSB, so unless you find information stating otherwise, I would say that you are stuck with 400MHz FSB Pentium M CPUs.

 

Click 'Go Advanced' which is next to the 'Reply' button. On the Advanced page you should be able to manage attachments, and upload the html report through that window.

 

Thanks for your time and effort for checking it at the net. I appreciate your help. Ok the details as follows...ATI chipset RS400/RC400/RC410 Rev 1.0. That's all it says.

 

Actually there is which I found at Asus forum (link below) that setting the switches to “1” chances the FSB from 400Mhz to 533Mhz.

Does it make sense with you? Your comment pls

 

If your laptop features the jumpers, then sure! But you will have to pull the dear thing apart..

 

Ok message noted. I wanna ask your opinion concerning the forum below...

http://www.tomshardware.com/forum/56470-35-laptop-schematic-diagram-wiring-diagram#t225913

Does it make sense with you as to how Nomad (item 2 from Asus forum) got a GPU overclocked by increasing the FSB from 400 to 533Mhz as it was also made a comment by frozenlead at Toms hardware forum?

 

GPU was overclocked because it is integrated into the northbridge chipset.

 

So are you saying it's possible? What if GPU is not integrated then would you say not possible?

 

If the GPU were not integrated, it would be very unusual for it to be overclocked with the CPU's FSB.

 

I have been trying to figure out since yesterday either I will do it or not to chance the switch into "1" position as mentioned in the Asus forum by Nomad. If you were in my shoes and given all the above info, Would you do it knowing you're 101% confident that your laptop will just run smoothly or otherwise you wouldn't do as it does worth it and don't want to take a risk? Your opinion will be highly be appreciated. Thanks

 

I've got the same problem with upgrading from Pentium M735a to M770 on my Asus A6Vm laptop. My installed CPU M770 shows max 1595MHZ instead of 2133MHz , FSB remains the same, i.e. 400MHz. Motherboard Intel Mobile i915PM. Any comments?Advices?

 

2133MHz / 533MHz * 400MHz = 1600MHz.

 

There is a jumper near the CPU socket that allows you to select between 100 fsh and 133 fsb. Move the jumber to the next position.

I don't understand why you did spend your money on the M770. You could have tried this instead http://www.notebookreview.com/default.asp?newsID=3226&article=pin+mod

 

it wouldn't cost that much anyways... pentium M CPU's cost almost nothing nowadays.

 

Thanks, could you post any pictures with the jumper(s), where can find the jumpers and what is the appropriate position for FSB 533( because official service centre is not in the know about jumpers, so I' m supposed to do all on my own)

 

I'm not an asus owner so it is a little bit hard for me to say.

Check this. I found couple of photos online


I can't see the (two) jumpers in either photos so my guess is they are underneath the plastics. I'm trying to find a better photo of the A6R motherboard. If I find one I'll post again

 

Thanks again, but I actually have A6Vm not A6R

 

Sorry I thought you have the same laptop as the OP.

There must be a jumper or even two somewhere, possibly hidden under the plastics. Or it could be an option inside the BIOS. The A6Vm was sold with various Pentium Ms inclusing the M740 and the M760. In addition it has a intel i915 so the M770 should run in it at 2.13Ghz.

If you don't find a jumper, and you don't find any option to change the FSB in the BIOS, try resetting the BIOS as this might help. I'm mean that you BIOS might be still believing that your using a CPU with 100Mhz FSB like the M735 that was originally in it.
To reset the BIOS locate the CMOS battery and remove it for 30 seconds to 1 minutes.

 

Thank you for aid, I'll try

 

The jumper/switch is located under the heatsink/heatpipe. Try to unscrew the 4 philip screws at the heatsink as shown in the 2nd photo. There you can see a tiny switch/jumper soldered it to the board.

 

Laptop sees M770 correctly in BIOS.It's no option for altering FSB through BIOS. .I've reinstalled the BIOS through Easy Flash- no changes in FSB frequency.I booted laptop from Live CD(instead of Windows reinstallation as was advised by service centre) - no changes. So I'm going to search for jumpers.

 

Problem has been solved - I've found the FSB jumpers (see attached image) and now CPU can work at best performance.Thanks to all for help.

 

Hi Guys. After my brother-in-law read your post he also wanted to change his Asus laptop FSB from 400 MHz to 533MHz. However we noticed that his motherboard component layout is totally different from yours as seen in the photo. There's no marked in the motherboard that says 533 MHz or 400 MHz instead “1 & 2” (vertical) and “5 & 0” (horizontal) marked at the jumper/switch as shown in the photo. Currently the jumper/switch is set to "0" at 400MHz. It can set be set to "5" but we are not sure thought if that setting is meant for 533 MHz. So I suggested to him to post it here first for your help. Does anyone of you guys have done this before setting the jumper to "5"?

 

First of all I'm talking about Asus A6Vm. Secondly, in fact that is not an exaxct picture of my motherboard but picture sent by one f forum members, as for my motherboard-it looks much alike as yours-there is no mention of frequency. I switched the jumpers in "off" position. I stress that I'm talking about ASUS A6VM Intel Mobile i915Pm chipset

 

Ok Noted. Sorry for the confusion earlier. My brother in law's laptop is also an Asus A6Vm. Would you pls send us the photo where we can see the switch and the components layout of your motherboard for our reference purposes only? Thanks in advance for your cooperation.

 

The picture http://forum.notebookreview.com/attachment.php?attachmentid=47694&stc=1&thumb=1&d=1269967803 is correct as for that jumper. Your brother has to switch the depicted jumpers to "off" position and FSB will be 533MHz

Here is an actual picture of my motherboard A6Vm. You need to switch them both to off position to get 533Mhz FSB

 

OK. Thanks. Will tel him.

 

Regret to inform you it did not work... The laptop won't boot up the XP and turned the screen into blank after we switched them both to off position.

We noticed that the location of our socket actuator, as shown photo below with green dot marked is upside down to the switch/jumper (underneath the heatpipe/heatsink with red dot marked) compared to yours. Your socket actuator is just beside the switch. Likewise our motherboard components layout at the right side of the photo below is totally different from yours. So any idea as to why it did not work???

 

Sorry, I'm not much of a technician actually.I did it with my Asus A6Vm and it still works. I have no idea why your layout is different from mine. It would be sensible to contact Asus service centre in your region.

 

The Asus service center advised us that they would not recommend to modify any setting in the motherboard as it might affect the performance. Anyway we will just wait for other forum members to post their comments. Thanks again for your help

 

What type of ram do you have? if it is DDram is it PC2100?

Have you tried with one jumper at the time instead of switching them both simultaneousy?

 

The ram is DDR2.. PC2 5300 MHz. Yes we had already tried with 1 jumper at the time. But still the laptop won't boot up the XP and turned the screen into blank :-(

 

So basically when you mess with the jumper your laptop turns ON but you can't see anything on the screen. Is this right?

Or do you see the Asus logo and then a black screen?

If it is the latest then the you might have succedded upping the FSB to 133 when changing the position of one or both switches. If you're in this case is simply means that windows is not able to detect the new CPU with it's right frequency. If this is the case the fix is relatively easy.

EDIT:
Have tried reseting the BIOS after changing the position of the jumpers? this is done by removing the CMOS battery for a couple of minutes.

 

We can't see anything on the screen not even the Asus logo. It’s totally black screen. No we haven’t removed the CMOS battery yet. We can’t locate CMOS battery unless we remove the whole back side cover of the laptop. Do you think we still need to reset the bios in spite of we don’t see the Asus logo?

 

I'm not entirely sure but you wont be losing anything by trying it. Before removing the CMOS battery, try this:
Remove the main battery and the charger. Then fold the power button for about two minutes. Put back the battery, connect the charger and test.

 

Hello, I finally got a pentium m 740 to work on my asus a6r notebook!
