Overclocking a dv6500t?

Hey everyone.

I want to overclock an HP dv6500t's Processor. It is a T5250 (1.5GHz), i was hoping to push it up to 2GHz.

But theres no overclocking in BIOS, im almost positive. So, are there any programs to overclock the CPU With? Thanks.

 

You try SetFSB?

 

setfsb is the best.
also try clockgen.

check the thread in my sig for some nice info on overclocking with setfsb and clockgen and some hardware methods.

It is good to know what PLL (clock genorator) your system uses.
You can look on the motherboard for it or if you have a maintenance manual for your notebook then it should be written there.

BTW, if setfsb doesn't work can you post what happened here so we can try to get it working. That's what's good about setfsb, if it doesn't support your PLL you can make it support it by sending a quick email to abo (creator of setfsb) and he will update setfsb with your PLL working.

Also setfsb has a very nice diagnosis mode, where you can change the PLL registers manually. So you can test if your PLL has a blockade dissallowing overclocking. If that is the case you can read how to fix that in the thread in my sig.

 

Ok. I downloaded them both.

On Both I see a ton of options in a list (My PPL's?)...Which one to I choose?

...That list happens to be from ClockGen, but SetFSB has the same options...

 

try all of them.
start with ICS and then silego since they are the most common.

unless you want to open your notebook and read it off the chip.

Edit: start with setfsb first because it's the best program. forget about clockgen for now.

 

Ok. I only first tried Clockgen because it downloaded first.

Ill try each and every one, lol, and watch CPU-Z to see if speed goes up.

 

if anything interesting happens in setfsb please describe it, like I said before setfsb is easy to troubleshoot.

 

Well, the first couple PLL's worked, but setting them higher made no speed difference on the CPU.

Most of them Gave me a SMBus or PLL ID Error.


And Whoa! The first RTM one (RTM520-39D) Made my screen go completely grey, just Getting the FSB Speed.With a high pitched buzzing sound...
Not trying any more RTM's. Moving onto the next.

Edit...
W83195BR-25 came up, but trying to set it did nothing. just went back to where it was perviously.
edit 2... same thing eventually happened changing the W ones. Gray screen, high piched buzz sound.

also, under Current CPU Frequency: internal. It is set at MMT. Should I change to QPC or SLP?

Ugh, and in Clockgen, setting/Applying the speed to one of them (that worked in SetFSB) made the grey screen go again.

I think HP does something to make this happen. To block Overclocking

 

I have overcome what toshiba did to block overclocking. I had to move a resisitor.

can you give me a list of the plls that worked?

 

Hmm. Yeah, im not up to anything like that.

Yeah. Basically. These three... But still gave no speed increase when increased, and now they seem to not go down back to what they were.
ICS9148BF-26
ICS9248BF-87
ICS9248BF-96

 

can you select one of them and then click on the diagnosis tab and then click on "getfsb" and then post a screenshot here?

 

Yep, sure thing. Here you go.

 

what CPU do you have. I doubt that is the right PLL because it thinks your FSB is 50mhz.

Edit: sorry, I see your CPU in the OP. your FSB is 166mhz. so that is the wrong PLL.
Try some others, just as long as they allow you to press getfsb.

 

This is a T9300 im trying it on. FSB is 800MHz. lol

 

ok then your real FSB is 200mhz (because intel is quad pumped so therefore you get 800mhz).

still it is the wrong PLL selected.
try some others.

 

ok. so look for one that says 200, and post that one. will do.

 

exactly

BTW, is there anyway you can see your motherboard without voiding your warrenty?

 

Well, i tried most of them... and almost all say 72.5 :/

Some 50, some 80...

I can see some small sections of it by removing my keyboard. Its already out of warranty. But i dont feel comfortable soldering or modding anything inside really.

 

If you can see the motherboard you can find the PLL.
It is a small chip which is sometimes near a crystal that says 14.318mhz.

If you want I can give you a photo of my PLL.

If you find the PLL on your motherboard you can then download the datasheet for it. I can help you find the datasheet.

Then we can makle setfsb work. you need to know your PLL first though.

 

Ok, I will look tomorrow and post back.

Thanks for your help so far.

 

I just finished putting my dv9700t back together (I have a dv6500t as well but I'm not going to open it too)...

and the Quanta 30CB board in the 9700t has a RTM875T-606 PLL chip. I'm guessing, since the only (noticeable) difference between my 6500t and 9700t is the RTL8139 vs RTL8111B (gigabit) ethernet that it's highly likely the 6500 uses the same PLL.

It'll likely be needing a pin-mod per http://forum.notebookreview.com/showthread.php?t=429717 anyway, but that should get you started.

Hope that helps.

 

A custom setfsb with RTM875T support has been posted:

you seem really desperate... get a desktop

 

^^ Hater.

Have a desktop. i7-920 running at 4.2GHz, thank you very much. Some of us just like to tweak and explore to learn new things.

Yeah, saw that too. My notebook crashes right away with that 250MHz FSB bump - the RAM SPD's already 5-5-5-15 and it cannot likely take the extra speed. Using that, I'd probably have to mod my SPD using Thaiphoon Burner or what have you, but don't know if I really want to do that. I think what I'll end up doing is the pin-4 mod at some point in the future for the 1MHz FSB increment granularity.

UPDATE: I managed to overclock it to 3.13GHz, see here.
