For all I know this motherboard is pretty limited in FSB since it works with 1066 strap... I think I got a "little" lucky :cool:
Thanks to Micutzu who was crazy enough to push vcore up to 1.7V (in tests) :eek: I made it this far : 468x8 SPi 1MB an 465x8 3DMark01SE
BIOS: 1.5
Voltages: 1.675 Vcore, 1.45 Vmch, 1.7 Vichio, 2.4 Vddr
Cooling: Arctic Freezer 7 Pro
nice clocks.. :D hehehe whats your temps?
'round 67-69 at the time of those benches :D
cool ambient?? Windows open?? :D
yeap :D... I must change the conductive "cream" under the NB and put some bigger blowers on the whole setup ;)
Temps outside : 'round 5-7 degrees ... inside : dunno :(
Yeah you got pretty lucky. I use 430x7 1:1 daily with a 6300. VCHIO stock, VMCH 1.4v, Vcore stock, Vdimm 2.1v. 440 and above needs VCHIO raising, but 450 seems impossible even with the highest setting... Will try higher vcore later (only tried stock so far), but my guess is that I need more VMCH or VCHIO.
*edit* - When I say impossible I mean "impossible to make it stable". I can boot 450, into windows and stuff.
nice cpu

http://valid.x86-secret.com/show_oc?id=135651 <-- another over 500 FSB :)
LN2 and other mods.... cough cough... :DQuote:

Johnny's I believe was done using phase change cooling on NB. Will point him at this thread tho and he can explain.
512 was hit here using the stock NB cooler and ~ 1.88 vMCH. Only "additional" cooling was some dry ice pellets piled ontop of the NB cooler. This dropped NB temps to ~ 25deg (probe on side of the sink)
Slapping a waterblock on would probably give a similar effect would imagine chilled water would give better results still.
Not really extreme cooling lol. Only mods on the board are vFSB and vMCH. vFSB is still pretty much stock afaik :)
OK you can get over 500MHz using a decent air cooler on the NB. The trick is a few extra tenths of volts on the chip, and things are safe so long as you keep it cool. BIOS versions 1.5v and 1.9v are good for this too. The phase cooling was there just to get a WR for the FSB speed :D
BIOS 1.9v, wtf? hehe *edit* - Nvm, you meant BIOS 1.5 + 1.9v on vmch right?Quote:

Out of curiosity: how high was ur vichio?
Check FUGGERS thread, its the bios found in there.Quote:

Had no idea there was this beta 1.9 version... Is it better than 1.5? I'll try to find FUGGER's thread, but if anyone has a link I'd appreciate it :)Quote:

And weir,d vichio actually helped a bit when I tried to get 450 fsb stable... But I'll stick to 1.5v
Thanks for the help guys, when (and if) I mod the board I'll post the results here, I see my e6300 crying already! :D
is that 69 core temp or 69 mobo socket temp?
if the former, i hate you :( I get 74c at 1.535v right now, at 75% load too, 3.6 GHz.
Core but environment temp was under 15 degrees :DQuote:
is that 69 core temp or 69 mobo socket temp?
I said... unmodded and CPU air cooled... I don't think that the link you posted is important since it's in a total different category ...Quote:
Unlikely you'll reach 500FSB in that case. However this is Xtremesystems - voltmods are standard ;)Quote:

But only just 3704, only bench stable
CPU got a little hot but, around 77 80 degrees celcius, mobo around 50 degrees celcius.
But unfortunately my AB9-PRO died. I benched and all went fine, but when i shutdown the pc had problems booting.
Its not because of settings, but the board is just dead as hell
I pushed mine at 436 for about 100 hours and it was fine, decided to do a speed run with the latest beta at 485 and killed it. It is back at abit for investigation now. Sometimes the need for speed kills. ;)Quote:

I finally broke 4Ghz, e6400, 500fsb :toast: :banana:
I could do 463fsb benchable on 145v Vmch, and 450fsb full stable.
I did the Vmch pencilmod made by Ntfs and could go up to 2v (motherboard could handle 2v :P)
I can run 3dmark over 3800mhz, but didn't try higher.
Can do superpi 1M at 3940mhz, if i remember correct.

I need other NB cooling to get 500fsb more stable, this Zalman NB heatsink can't handle the heatload.
