Overclock D600 1.6G to 2.13G (hardware modification with photos) - Page 2

Hello together!
I hope it's okay that I put this post back to live.

I'am new here.
First Big Thankyou to bosslee!! I Have within an hour put in the resistor into my dell D600.(with disassemble and put together) Your Pics are a very goood!

But now my problem. I have up to now 2x 512mb kingston 266 RAM.
If i start my d600 it will crash in the bios.
Now i have seen the solution is a combi of a small 266 ram and a bigger 333 ram.
My questions:
Can i use one of my kingston and a ohter one with 333mhz? How can a 266mhz module manage to run on 333? (if i have to take special memory modules please give me a example)
Why didn't work 400mhz modules on this config?

My Dell:
1,8Ghz P-m 745
2 x 512MB Kingston 266

- Sorry for my language,... I hope every one can understand me because my english isn't the best!! -

Best wishes to all.

Da_Basti,

I don't know if you have resolved your situation with the "crashing" but it seems to me that it could be that it is because you have the 1.8 GHz processor that overclocks to 2.4 GHz and that could mean that you don't have enough voltage to handle that level of speed.

But if you are still around, perhaps you could clarify what happened with the resistor. Bosslee seems to have suggested a 1 K resistor between A and B and a 1 K resistor between C and D. Furthermore, arthur 2501 and rob_s mention something about C and the area around C but not anything about A and B. Hence, Bosslee seems to suggest two 1 K resistors but arthur 2501, rob_s and yourself seem to suggest one 1 K resistor. And it seems as if all three, perhaps all four of you, positioned the resistor to the right side of C and D. And, of course, arthur 2501 and rob_s seem to suggest the resistor covering something "south" of C.

Furthermore, it could be that someone else on this thread has succeeded in doing this overclock and perhaps could mention whether this overclock involves one or two 1 K resistors, and if it involves one resistor, whether the resistor should be between A and B rather than C and D.

Hello OC's

I also have done that OC and tried both ways, the simple method, a wire between C and C_, with this one the Notebook don't boot, only the Capslock blinks, and then he shutdowns, i tried with diferent sticks of memory and combinations (266, 333, 400 mhz) always the same result , the other way, putting the 1K capacitator on the right of C,D, conecting to the C_ (the point below C), the way of the foto, the notebook boots, but he dont assume the OC (also tried with diferent sticks of memory and combinations 266, 333, 400 mhz), when i check the BIOS and the CPUz still a 1.5 Ghz pentium and the memory is at 266 Mhz...... well my next step is to do like the original post refers in words "Conect A + B" with 1k capacitator...or.... conect A + C_ with 1K capacitator... etheir way i will post the result here...

I forgot to mention, i got one Dell D600, 1.5 Ghz with 1Gb of 333 Ram (266 speed used), running Mandriva 2009.

aesir,

The situation with your Latitude D 600 could have something to do with the PLL. It could be that the PLL in your Dell 600 is ICS 950810. Bosslee and others appear to be working with CY 28346.

It could be, however, that the overclock works similarly for ICS 950810, and the overclocking actually has to be about connecting a 1 K resistor to A and B.

Hi

I checked that I have the correct chip PLL, maybe my welding wasn't well done or the 1k resistor was broken, i will try again with a different resistor and check that the welding is well done, that will be the next time i got the courage to dismantle the laptop again...loll

One question... the new speed is correctly shown in the BIOS?

Tks for the reply

Yes you should see the right CPU speed in the BIOS under "maximum speed supported" or something like that.

thanks for the great tutorial. You mentioned a software solution though. Can you give us the name of the program that you use for Dell d600 (PM 1.6)

I tried to use SetFSB but I dont know my PLL chip number (yet) and I was also wondering if I cant find my pll number in the dropdown list in SetFSB does that mean that I cant overclock my cpu with it?

He just mentioned that a software solution was possible, not that it was feasible. Without the PLL (nobody has it afaik), you're just gonna have to rely on hardware methods.

Thanks for the incredible tutorial. I plan to mod my D600 this weekend. I know he said to put the resistor between A and B, but on the picture where did the put his resistor?

It's looks the bottom of the resistor is soldered on the track of pin 55 which looks like it is connected to A and the top of the resistor is soldered to D. Am I seeing this correctly?

Well, analyzing the photos 7 and 9 (the red arrow marking the 2nd pin from top left of the PLL and following the copper foil this pin is linked to A. Similarly, the green arrow marks the 3rd pin, which is linked to C), I'd say that the 1K resistor connects the points A and D, to turn A a high potential too (just follow the copper foil from the PLL pin to A point at photo 7 and you will notice a soldering drop, where the resistor is soldered).

I think I have helped, please comment. Thanks.

Hi mate,

I do not really see where do you attach it, can you take some more pictures of the attached 1K resistor area, please???

Cheers

Has anyone done this mod? I want to know whether it's worth the effort. How much is the performance boost? Please let us know.


Another thing, since we are talking about OCing laptop here, I was thinking of mounting a small switch to control the voltage on those pins. What I am thinking is, if the OCing actually improve the performance, I would use OCed @ home with extra fans on it and simply turn off the OCing when I am travelling with batteries.

Just looking at the picture OP posted, it seems like the reference voltage changes the PLL setting, so theoretically it should be fine to wire a switch somewhere in the housing, which will be a little more work..

Theres no need to make a hardware switch. There are plenty of software solutions to limit the maximum clockrate on battery.

That's right! I am not familair with all these neat software. Anyone still using their moded D600? What's the combination of RAM card you are using?

1GB PC2700 + 256MB PC2100?
512MB PC2700 + 256MB PC2100?
256MB PC2700 + 256MB PC2100?

Please let me know! I want to try this mod and I need to get a PC2700 card.


Thanks,


Mike.

I haven't posted on this thread for a while. I have overclocked 4 laptops now. 3 of them were d600/600m (same motherboard) and the other was a i510m (uses the same PLL chip). The sound worked fine on all of them when overclocked.
I couldn't get a CPU faster than 1.6Ghz to overclock, the 1.7 Ghz I tried wouldn't even POST. Someone mentioned earlier that their laptop would just sit there blinking lights at them, it could be the CPU cant handle the overclock or I think this could be due due to the ram not being seated properly or just that the ram is overclocked too far.
I had to test a lot of ram to find any cards that would still work with the 33% overclock. After a lot of trial and error I have two 512MB cards and a lot of 256MB cards. Of the 1GB cards I tried, none of them would handle the overclock. About 50% of the 256MB cards I tried would work witht he overclock. Some would work but show errors when using a ram tester in windows so were relegated to normal (non overclock) duty.

Would you happen to have the specs of the ram modules that work? Brand etc ...

Welcome back

Most of it is DDR 266, one of the 512MB cards is Kingston. The 256MB cards are generic Dell ram and others (Samsung etc) I think the best way is just to try out different cards. I should also be really cheap now on Ebay etc.

my laptop freezes (stops suddenly, not responsive), quite often and I would like to fix the problem. From the previous posts, I guess it's the PC2100 ram that can't handle the OC. For those who've done this mod successfully, could you share the ram part number that works well? I'm thinking it's the PCB and other components preventing the ram card from running well with... another possible mod?? Here are details about my setup: Banias Pentium M CPU 1600MHZ (0.13um) PLL was PIC453450 1x Samsung PC2100 256MB 1x Samsung PC2700 256MB Please help. Thanks, Mike -

I am not sure if it is the PC2100 that cannot be OCed or is it the issue of mixing different ram speed modules when OC-ing.

Why don't you try to put in 2 modules of the same speed first and see?

cheers ...
