2. On my IC7, Auto is very close to max performance, but not on the IS7 (which has the same chipset as AS8). Here you have a link to some previous testing done by me, with settings you can try:

There's a lot of more memory related things in that thread regarding PAT if you're interested.

Also, search for as8 by hipro and you'll find thread where he has written what kind of settings he's used to reach insane FSB speeds on the AS8.

Thanks a ton. I got PAT enabled but my bandwith is still in the 65% range. Gonna look at that link you gave

Tried 667 and it hardlocked shortly after windows booted (5mins or so) :(:bsod:

As a side note, PAT/GAT was never intended to be enabled on the 865 chipset. These are some kind of optimizations that the manufacturers try to imitate.
That might be why it won't work.

This i getting a little OT here, but can you post in your thread under the Intel section exactly what you have tried and what enabled PAT for you?
Also, for more info and a tweaker, check this thread:

Try to find the CTIAW program, it is great for checking PAT, timings, bandwidth and so on.

is normal that at 243mhz i have pat enabled???

p.s. plz can some one link to me the post hipro posted the settings to reach hight fsb??? thx...

Thanks... I tried all of those things but still no go. Waiting my BIOS from Abit :stick:

Enyone tryed Vsb mod yet ? Have to test will it help getting higher FSBs, like it Vsb helped on 8RDA case :D I think i may help also on AS8, but not sure.

Oh, yes, and the pic for mod:

Can anyone maybe help me?

I have done the droop, chip and agp mod at the as8 board from my brother.

everything was working fine. I put vchip to 1.52v, agp to 1.7v and the droop was first time small enaugh.

the 3.0 p4 was able to get 274mhz, before only 266mhz stable.

but after first time setting vagp to 1.75v the vchip mod has no effect?!

I tryied another vr cause I thougt the first one was broken, but with a new one the same thing, vhip is at 1.21v and nothing will happen.

I double checked the soldered cables, unsoldered and resoldered them but no effect will happen to the vchip after turning around the vr, still 1.21v

Did anyone know what happened to the mainboard? I hope you can understand my problem ;)

Everything else is working fine.

Thanks Benny

Hi.

Let's say I am an averaga overclocker...and that my max FSB is about 275MHZ. Which mods are recommended for me to do? Beside the vdroop mod. Will others really matter or are they just for hardocore OC?

PS, where to put extra heatsinks and fans?

the NB vmod would help you get more fsb, or a more stable 275 fsb.

ok ive done the vcore, droop, vchip, and vagp mods, there all working pretty nicely :P Thanks hip.

You're welcome guys.............. :)

PS.....Try to work the AS8 with the 800 stripe and not with th 667 one........... ;)

hey hipro i think i found a way to trim vfsb up higher :) Ill talk to ya tomorrow

-CaT

um so 1.664 for the vdroop is the best?

my VR is set to 1.686Kohms and that works the best for me...

-CaT

what numbers do you get?

1.45 idle 1.44 load

i find w/ vcore and droop mod, it flucuates less

-CaT

alright thanks.
New question, if i do the vagp, how does this hlep my fsb,(right now im at like 270) and do i set the 50k trimmer to 50k?
Do you think it is worth it if i just want to go to 280?

Also could my card take 1.9v? Its a fx5200

by "the NB mod" you mean the vchip mod ?

i think im talkign about hte vagp mod.

All i could find at radioshack was a 1.5K resistor with 5% tol. I put it in and it goes from like 1.42 volt on full load to 1.44 on idle @ 1.4375 so I guess its okay?

sounds fine to me, atleast it's alot better then it originally was :D

Well not anymore lol I did a bad solder job apparently because i bumped the resistor when i went to install a video card and ripped the whole 14th leg out and the little resistor so my boards completely dead, I sat around for 8 hours trying to fix it but I just made it worse... Looks like I'll be ordering a new board off newegg lol.

that sucks.

Edited:

Do not try to give advice on faking an RMA :(

-Kunaak-

Oh it's too late to fake an RMA anyways I got so much solder after 2-3 hours of trying to fix it it was too hopeless to even grab the alcohol and acetone and clean it up ;-) Oh well its $88 or so new on newegg without the uguru clock so it's not a HUGE loss, at least I didn't fry the processor or something over $100

Your just going to throw it out?
