Overclocking dells

Is it possible to overclock a dell? (The earlier models)

with a hacked bios yes... with the dell bios no

You do that and screw something up though you really just lost a computer. I imagine flashing Dell PC's are not as easy as flashing built by "you" PC. Dells are not meant to be OCed or toyed around with. That is the reason they use proprietary hardware.

If you want to OC sell the dell and build your own system.

NOOOOOOOOOOOO!!!!

 

[LASTGUY2GETPS2]

lol. Only reason why i'm asking is because i got a pretty crappy dell pc for free (pII) and just want to give it more cpu power....does the intel piii processors have the same pin or configuration or whatever as teh pii?

 

[TheStu]

Maybe..... I know that the P2 only came in Slot 1 configurations... the early P3s came the same way I believe but I could be wrong.... the later P3s were socket 370....
Anyway good point phreek... i neglected the proprietary aspect of it....
you could fiddle with it a little and not have much to lose since it was free after all

What do you make of this: http://support.dell.com/suppor...;s=gen&~mode=popup

early p3 did come in a slot1 flavor. I believe they ran up to 1.0ghz stock. I have no idea about overclocking dells.

Overclocking dells.

Goodluck.

i have an old dell with a Pentium Pro and i was able to overclock it from 180mhz to 233mhz using jumpers on the motherboard.

 

[Spikesoldier]

i think you can block a pin on the slot1 242pin connector to make it run from 66 to 100 bus speed

 

[LASTGUY2GETPS2]

Okay. As of now the processor has a huge heatsink and a fan , not to mention the side of the case is open. Will that provide enough airflow so i won't FRY IT?

 

[PhoenixOrion]

deschutes/p2-based dell mobos will have that jumper that you need to relocate to whatever bus speed using.

most dells way back when would have jumper cap on default 266/66.

You may be able to use SETFSB and CPUFSB if you can find the correct PLL on the board

In certain configurations you can do a pin mod in conjunction with a volt mod to get higher speeds. Whether it is stable...

For instance, if you have a Celeron 2GHz or Pentium 4 2.0A in a Dell that officially supports 533MHz FSB, then you can break a pin off and the system will detect it as a 2.66GHz chip. A Celeron 800 will become a Celeron 1066 and a P3 550 will become a P3 733 on socket 370 boards that support 133MHz FSB.

Of course, YMMV. Some BIOSes get stupid if the CPU isn't in their microcode meaning a P3 550@733 may be fine because a P3 733 exists and a P4 2.0A@2.66 may be fine because the 2.66 exists, but the Celeron 1066 and 2.66 (Northwood, not Prescott) didn't exist thus may not work if the BIOS doesn't like it. Also, if the CPU just can't run stable at that overclocked speed then you're SOL.

If you have a PII dell, then you may have an LX chipset or BX chipset. If you have an LX, then you are sort of out of luck. You may be able to go up to a Celeron 533 (or if you're really lucky, you might be able to go to a celeron 766 with the proprer adapter-- I actually upgraded a Dell Pentium Pro system with the FX chipset to a celeron 766 at one point). If you have a BX chipset, then your options are a little more open. If you really want to play, you have to get a Powerleap adapter. They allow you to force the mobo to use 100MHz FSB easily and they allow for Vcore overclocking. I used one of these to run my parents' Optiplex GX1 with a celeron 633 to run at 950MHz.

how? the ppro uses socket 8, and nothing else does. the celeron used slot 1, socket 370... but never socket 8. and the fastest ppro was a 200MHz... i kinda doubt the ability of the mobo to run a 766 cpu.

 

[BigBadBiologist]

The FX chipset actually support PII CPUs (there wasn't a whole lot of difference between a PII and a PPro except MMX support). Powerleap realized this and made a socket adapter for Socket 8 so that you could put a Socket 370 FCPGA CPUs in there. There were some mobos that didn't work with the adapter (like the Asus P6NP5 which I still have) and even the ones that did tended to have cache compatibility issues.

If you think about the Overdrives that Intel sold for the PPro, they were pretty much celeron 333s.

If you OC the dell it will proly...no Definatley void ur warranty, but of coarse you already knew that.

yeah...their tech support is crap at points...damn outsourcing!
