I have a Dell XPS 410 with a Core 2 Duo E6600. I have read that there are a few tricks that may be available to overclock this cpu despite being locked by the BIOS. For example, see http://www.starless.nl/overclock.html and http://starless.nl/pinmod.html.
However, I am a complete novice at this stuff, and I just want to get some expert opinion on whether either of these would work with the bios on my motherboard, which, if I am correct, will not accept any of Core cpus above 1066 MHz. Since my cpu is already defaulted to 1066 MHz, would I be able to perform either of these modifications (assuming everything else worked fine)? My warranty has long since expired, so I am not concerned with that aspect of things.
Also, what is the best processor I can put in this thing? I think for the quad cores, it is the Q6700, correct? What about for dual cores?
Thanks in advance.
Niether method really has anything to do with the bios.
Clockgen may work, check the PLL chip to find out, the gain can be as much as 18%. If you have the right chip do a Google search for Clockgen and you'll find some site's that still have it available for download.
The voltmod is pretty much guaranteed.
The Q6600 would be the best bang for the buck.
Thank you very much for your response. I know that you have done a lot with your xps 410. I just want to clarify something. I thought Dell's P965 chipset could only allow processors up to 1066 MHz on the fsb. Is that correct? Is the voltmod that you mentioned the same as the tapemod (or pin mod) shown in the picture at the top of this link: http://forums.nvidia.com/index.php?showtopic=58629?
If so, are you saying that defaulting to 1333 MHz would not change the compatibility between the Dell motherboard and the processor? I keep getting conflicting information on this, and I am just trying to get a better understanding. I have not checked my PLL chip to find out, but I plan on doing so. It is my understanding that I check the PLL with clockgen. Is that right?
Also, as a side note, would you mind posting a link to your pictures of your modded XPS 410 if you still have them? I have tried using the search function, but I have not been successful in relocating them. Again, I appreciate the help.
I was refering to the pinmod that you linked to previously.
No, it won't change the compatibility, we had a member ( Peter.. something with numbers...., can't remember ) who had a much better grasp of this than I do.
I never used the pinmod because Clockgen worked for me, but Peter and others did, without problems.
You'll need to physically check the PLL chip by opening the case ( I needed a magnifying glass to read those small numbers ) and then see if it's on the list provided by Clockockgen.
Pictures of my D9200, oh boy, I still have the picture's, the machine now resides with my nephew, he's got an E6400 in it, oc'ed to 2.4.
With my HX620
Good luck playing with it, keep in mind that should you wish to do more overclocking most of the parts from the Dell can be used to build your own at a cost of around $300, depending on the parts chosen.
Thanks for the help and additional information. I will see what I am able to do and hopefully post some results.
Edit: I think I found a link to the old thread which also went into detail about this issue.
Did you ever have any luck OCing your XPS410 with clockgen? I have a 410 with an e4400 (2.0ghz) and want to overclock it. I've been trying to do so with clockgen and have had no luck. I'm pretty sure our PLL is SLG505YC56. However, when I choose that PLL and attempt to increase the FSB setting (even a small increase) my computer freezes and I have to manually reboot. I've tried Starless' guide and it doesn't seem to make a difference. Did you have any luck with clockgen yourself?
Wow, this response is only about a year and a half late. Sorry. To answer the question, with my 2.4 Ghz dual-core processor in Vista, I was able to successfully overclock it. Sometimes it would freeze as I was increasing the FSB setting, but I did manage to get it up to about 2.8 Ghz after a few restarts. However, I did not stick with it for long. I believe I had to disable UAC, which was a little annoying (although UAC is itself annoying). Furthermore, even though clockgen was supposed to automatically start each time I started the computer, it often would not. As a result, I would have to start it manually, which would sometimes freeze the computer. In the end, it was just not worth the constant hassle, but I may give it another shot.
own a DXP061 and the PC acts exactly like You wrote, Gasparin ! OC - Success-rate is about 50% and no matter if overclock-speed is
267 FSB oder 312 FSB. So its not a problem of the "weak" power supply.
So here, we pained Dell-owners, wait for the "golden" solution of the riddle ...
...god, give us the motherboard-hardware-mod !
Own a DXP061 and the behaviour is exactly the same You wrote. No matter if
I oc FSB 267 or FSB 312 , success-rate is about 50%, 50% freeze.
So it’s not a problem of the power-supply or uac.
Who can solve the riddle ?
We need a serious motherboard-hardware-mod !
Honestly, if you want to overclock, I would build your system from scratch yourself.
Pre-built systems from vendors are designed and validated at atock settings, and don't have the cooling hardware, or configuration tools (in the bios) necessary to do any amount of real tweaking.
