Netburst support on P45 motherboards

[KonaKona]

Yes it's 2025, nothing happened.

I remember ages ago my Gigabyte P45 something or other would support Pentium 4 chips, as would all 775 chipsets to my knowledge, but would not allow me to adjust the FSB. Today while digging around on hwbot I found that some people were in fact, doing overclocks with P45 based boards. And X48, X38, P35 and so on. I knew at least some P965 boards supported it, but I didn't realize the newer chipsets could still change FSB.

I assume this might vary bios to bios, or be something that "modded bioses" can support, or what have you. Is there any real documentation about this out there? Or did I just get unlucky with my Gigabyte and "most" boards which have higher end chipsets should have full overclocking support?

P965, P35, X38, X48, all of them were intel Core 2 chipsets. Last one i can personally think of that allowed fsb changes was X58. now if they did after that i have no idea, they might. I so badly wanted a Abit X38 and X48 board but never found them retail. Now if you find them on ebay they still go for mad amounts. On the title though, Netburst would be on P800 chipsets, i did use a Asus CT-479 adapter(if you can find one). Used it on a Asus P4P800SE board, ran a Dothan 720 on it. Dude that thing was sweet for gaming compare to P4 or Amd version at the time. It was nuts cause i had it clocked to 2.4ghz. Other people prolly pushed it further but they came up with their own mounting for using better heatsink then what came with the CT-479 adapter.

Netburst is a Pentuim 4, after that you have "Core" aka Pentuim-M(mobile only) Banis 130nm/Dothan 90nm/Yonah 65nm, Then "Core 2" takes the ground work of Pentuim-M and got a major upgrade, then put on desktop. Always relaible cpu that would max out at the same speed no matter what voltage you threw at it, Core 2 E4300 . I do not think i ever saw one of those break 3.6 or 3.8ghz. I would go look but forums purged old posts and photobucket purged my free account from back in the day.

I've got a P4 630 or 640 & an X48 board in the basement. I'll see if I can put the two of them together & see if they boot.
I seem to think the combo should work, as well as a P4 & P45.

Evil, P4 carried on to LGA775. I have several Pentium 4 LGA775 CPUs. I even have an Abit AA8XE LGA775 board that only supports Pentium CPUs.

I loved looking at y'all's CT-479 benching runs. Total beasts of single threaded glory!

please for the love of god!! do not put the P4 on the X48!!! #SAVE THE BOARD! Socket might be the same but that does not mean the chipset lines up with the cpu's architecture. i forget the exact chipset but i can say for sure P3x or higher chipsets will not work with netburst based cpus.

i know they went to LGA775, hope my other post did not give the impression it didn't. i was more breaking down the linage of the CPUs.

thats crazy to me, the last of the C2 chipsets still supports/works with a P4. :x

Hey, iirc even an Abrams tank can run on bathtub gin.... Kinda.

Embrace the cludging!

I did some more googling around and it might very well be that the "No FSB/Vcore on Netburst chips" thing (I might have been misremembering, no vcore not no FSB) was specifically an issue with Gigabyte boards. There's plenty of HWBOT submissions running Netburst chips on the aforementioned chipsets, which were nominally Core 2 specific. The 975X was right on the cusp and I believe were the first boards that would run Core 2 chips, as well as all Netburst chips. I thought only P965 would also support both, but I'm now pretty convinced that's incorrect.

And again, "support" in this case being full overclocking support. They should all boot and run at stock.

Funny to think of a P4 running on DDR3. But I mostly just want to know if I could pick up a couple of Netburst chips and overclock them in the same board I use for Core 2s
