max3 maxed out

[Shane5578]

my current setup

3.2 ES (should be able to do atleast 400fsb)
max3
pc4000 gold
geforce2 ultra
single wd caviar
win2k


max fsb for the ic7 max3 unmodified = 295 stable dual channel

max pc4000 gold @ cas2.5 = 265 stable dual channel, 285 single stable

they might seem low, but when i say stable, i mean at least 2hours of prime95 running simultaneosly with 3dmark01 then sisandra burn in.

i have also found issues, such as vdimm >2.9 not working when certain settings are used and cold boots.

You may want to trade notes with Kenneth Chong, he hit 340 ish with his Max3 with stock NB cooling. Then he cooled it with P/C and hit 36x fsb.

3.2 ES (should be able to do atleast 400fsb)

not any day soon....

[charlie]

400fsb, lol..........
Anyway...the 3.2ES only has like 14-16 multi's I don't believe the 3.2 ES goes down to 8X.........dunno'
And from what I've heard they don't OC very well...

these 800fsb HT ES cpus have 8, 12,13, 14, 15, 16 multis available depending on stock rating.

the 533 ES chips had only 12 multi at lowest.


anyway, i'm quite happy with the max3, it can do 300fsb, but not prime95 stable.

there seems to be issues with ES when lowering the multi, as i can't increase vdimm >2.9 don't work, i get very bad cold boots.

I am ditching my Max3 Shane - do not like it one bit. It's incredibly fussy and it's as quirky (IMHO) as the IC7. I could only get a 600mhz overclock with my L311 3.0C and the Max3. With my Asus P4C800-E and the same processor I am now running with a 1200mhz overclock - go figure

[Major]

phil stanbridge, IMO it would have to be a setting that you've overlooked in bios to account for the difference in OC. That's a big difference, my P4C800 will OC about 100mhz maybe alittle more than my IC7 certainly not 600mhz difference !

[macci]

my max3 maxed at around 300fSB too.. funny how mr. chong run it at 340FSB with NO NB cooling at all!...not to mention 2.4C@4.3G at 1.50V :P

[macci]

phil stanbridge, flash the latest bios and see if that helps.. it fixed mine

[phil stanbridge]

Guys, thanks for the replies. I am using 1.2 bios for the Abit - I presumed this was the latest bios. I had tried every setting I could think of to find the sweet spot. I managed to get my 2.8C to 3.92ghz once, but it was totally unstable. It crashed and I couldn't get booted at that speed again. I then tried the 3.0C which was untested at that time - I could only get a 600mhz stable overclock with that. Now I'm running it in my Asus and I can get into windows over 4ghz every time, and that's without the Northbridge waterchill.

I've managed to get my L310 3.0c stable to 3.67Ghz (245mhz fsb) on the Max 3 at stock volts, but any more (even one 1mhz fsb) and it will fail prime no matter what volts.. i am sure my problem is similar to Phil's so i have also ordered the Asus.

[Shane5578]

sorry to hear phil. oh well.

i think the otes thing is purely cosmetic.

did it really max out at only 300?
which chip was that?

hopefully in your case your talking about a 3.2

300 is rather easy to get with good cooling and a decent chip, I'd hate to hear all these people spending 230 on this super hyped up board just to get avearge OC's.

Here you go guys...12 bios with all the unhides..i did it yesterday.
says bigtoe mod1 as bios message.Spread spectrum is unhid and tweakable as is quite a few other items.

Remember this bios will invalidate your warranty and will not be supported by abit.I have the bios loaded fine and have been benching for 20hrs plus.If it kills your board i take no responsability..you flash at your own risk.

grab it here

[rabeb25]

can you tell me what else there is? so i know before i go flashing

[Tony]

Auto options for memory timings...spread spectrum unhid and tweakable..and a few other options..

TBH i wasn't taking much notice as i unhid them all as im mad busy compiling a report for OCZ on the board.

[Semper Fi]

what does spread spectrum do?

Used my mates 2.4C (does 3.55G stock voltage/cooling) R404ed so it wasn't the chip
At 305FSB I could just pass SuperPi 1M but going higher than that would give calculation errors (and this was done on ambient temp of around +15C). So its basically identical to the IC7 I had at one point. Also 5:4 FSB seems to max at 285.

same as both my IC7's...

they're fast for high multi chips but you need the P4C for the high FSB's, that is of course unless you get as lucky as Mr. Chong

[Major]

My IC7 maxes out at 292, nothing is stable above that with any of the chips I've tried.

Thanks...

did anybody test this yet? And what exactly does it unhide?

[rabeb25]

hmmm i wonder if my max 3 was above max fsb @285ish seeming it will do 280 with 1.7 volts, yet at 285 it is not stable at 1.9. I have never removed the stock cooler i spose i could check and see. maybe i did get a good chip afterall.

I have spoken with Abit and they are working on bios update for the 5:4 bug which has to do with CH5 memory.

Will it fix the bug where you have to keep the top GAT option at Auto when running any divider except 1:1?
