View Full Version : Abit NV7-133R with a Barton CPU

12-21-03, 12:18 PM
Can a NV7-133R with the new DW bios that adds Thorton support work with a Barton CPU? Becase aren't Thortons just Bartons with half the cache disabled? I was looking at the Barton 2500+ CPU specificly. Thanks.

Some peoples had Barton's working with the ABIT K7TA (KT133A) so i don't see why.

Aren't all Thorton/Barton CPUs bus speed 333MHz? So would the bios support the CPU at that bus speed?

Yes but you will have to underclock it... if it's still locked. so a XP 2500+ would run at 1.46GHz rather then 1.83GHz. However a person here unlocked his and ran it at 133x12.5

That would be me. :)

Yeah, my mobo/bios doesn't recognise it at all, perhaps thats why its unlocked. I could choose any multiplier I wanted.

12.5x was the highest my multiplier will go. Though I had to increase my cpu drive strength to maximum for it to work.

What do you mean cpu drive strength?

vcore, voltage the motherboard sends to the CPU. when you OC and you find a setting that's not quite stable, increasing vcore will often make it stable at the expense of more heat.

Not voltage increase. Drive strength was an option in the BIOS in the speeds/voltages screen. Value from 1 to 3.

I'd spend that $85 on an nforce2 board before I bought a 2500+ to replace an 1800+ that's perfectly fine.

drive strength != voltage? crazy. I thought we left those drive strength options in teh days of the Pentium MMX... oh well.

Well it is an old board.. But still going strong. Abit rock! :)

Abit does make some nice boards... then and now... my kt266a just won't do anything that deserves me selling it! It's just too cool for an older mobo! ATA-133, RAID, buttloads of OC options, and the ability to run a Barton chip @ up to 2250mhz if set up with the right components... ... heh, tweaked correctly it runs neck and neck with single channel nforce2 solutions in most tests... :)

...anyway... have nv7-133R's been shown to be stable @ at least 166fsb?
