best vp6 overclock of all time?

[kc8adu]

i have been doing a cost no barrier rehab of a abit vp6.
all lytics are now high quality jap.
tc's custom bios.
kingston gx150 ram.
all lytics on vrm outputs and the mlcc around the sockets paralelled with 470@4v tantalum/polymer chips and mlcc's.
psu is a fortron 350w with the same cap treatment.
solid cu hsf's.
polymer/tantalum/mlcc ultra low esr chips bypassing all supplies.
hitting this vp6 with everything i have that improves ripple and regulation.
stage 1 is running 2x p3 933 at stock vcore at 150 fsb.
folding,playing nws java radar loops and folding 3 days now without the slightest glitch.
so what was the all time best without all these hotrod parts?

Forgive my lack of Intel knowledge, but what do those P3s usually run at?

Re: best vp6 overclock of all time?

the ones i am running now are 933
at 150 fsb they show 1.05 ghz

Re: best vp6 overclock of all time?

i have two vp6s each running 1ghz cpus. one of them won't go past like 1025 or something like that. the other will go up to almost 1100. they both have cu heatsinks as well as polishing all four cpus and heatsinks. i was really bored.

Re: best vp6 overclock of all time?

Polished surfaces reflect heat.

Re: best vp6 overclock of all time?

i remember lapping celeron slugs in the bp6 days.
idea is not to polish for looks but to get both surfaces as flat as possible for best heat transfer.
well are 0069 and i the last to care obout the vp6?

Wow, very nice work and excellent results! I've made several BIOS's for that board, I think that one has Tualatin microcode in it, so a tually will run with the powerleap adapters.

Keep us posted on its stability!!

BTW, I have a couple tough dog VP6's I'm going to send to you to play around with.

[kc8adu]

Re: best vp6 overclock of all time?

i will take a shot at fixing them.
btw if you want the parts to "hotrod" yours holler.
i can send you some.

Re: best vp6 overclock of all time?

You're not going to change that NB heatsink for something better?

[kc8adu]

Re: best vp6 overclock of all time?

nope.
it runs cool with the air coming from the cpu coolers.
i do have a pair of p3 s 1.26 and some lin lin sockets to play with though.

I think I'll take you up on that offer. I had my VP6 running as a server, but I've since moved its data to another system and freed it up. I'm curious to try this now.

Re: best vp6 overclock of all time?

Greatest job EVER!

I have several questions:

1st - Do those MLCC need to be soldered to those VRM cap joints? and why exactly, I see this type of modding for the first time.

2nd - Those big caps around VRM and other parts are polys?

3nd - (an opinion) I really recommend swapping the chipset HS, it runs cool because it does NOT conduct heat pretty much - I wasn't able cross the 166MHz FSB without changing it, brushing the surface plain clean and adding some paste plus glue for a new and quite heavy heatsink with an active cooler - solved temperature mystery of mine.

4th - Ehm, I suppose with THAT modding you pretty sure reached a stable 175MHz at least . Anyways what's new in TC's bios updates? Mainly is the limit of 178MHz FSB pushed farther?

GREAT WORK again!

Re: best vp6 overclock of all time?

Achieved 173,5MHz ROCK SOLID - more info to be found here (scroll down pls):

Re: best vp6 overclock of all time?

OH awesome !

I tried something similar for VH6 - 2


http://valid.canardpc.com/show_oc.php?id=1127657

A bit high voltage. Could work at 2.0 with no prob. Really cold chips.
And stable as a rock.

[Shodan486]

Re: best vp6 overclock of all time?

YEAH! Slovans rule with Abit boards in terms of OC.

Anyways - OH MY GOD!!!! 204,05MHz FSB?!?!? Are you trying to kill me? How could you possibly crank it up so high? Is your board recapped / using very tall capacitors (thus raising the ESR) ? Anyways GREAT SUCCESS!!!

Pictures of the setup would be welcome!

[Pyr0Beast]

Re: best vp6 overclock of all time?

Board has 200MHz limit in bios !

Yeah. Recapped, some lytics, and some polys. Lots of ceramic & smart placement !
Changed power mosfets. Ice cold at 2.2V !

Also raised chipset voltage to 1.8V

Re: best vp6 overclock of all time?

I need turbo PLL for more clock. hehe. I could go 230 easily !

Really really stable board once you add proper caps on it.

I will post pictures if you want to see them. Do you ?

Board was recapped specifically for purposes of overclocking !

Re: best vp6 overclock of all time?

But is it worth it?

[Pyr0Beast]

Re: best vp6 overclock of all time?

Once I hit 205MHz FSB it was worth it )

5 hours of my time. 30€ worth of caps and a scope to learn something from recap. (One panny can hold entire load !)
