I found out something strange.
Disabling PAT gives me much better overclocking results at ALL multipliers below 13*. With PAT disabled I can get to the same speed with the 9*, 10*, 11* and 12* multiplier as I can with the 13*. This is really strange because it affects both the 11* and the 12*. At the 12* multiplier I could get nothing stable above 12*225mhz but now I can. Weird thing is that with PAT enabled it CAN do above 225mhz and goes up to 241mhz stable. It IS a motherboard issue I think because i have this problem with ALL cpu's.
I disable PAT by booting at 201mzh instead of 200mhz which I usually use for better performance. Ik think I'm just going to buy a P4C800-E Deluxe and see if that has the same problem.
For anyone having problem with their Dothans at a P4P800 SE, you should try disabling PAT because this helps at ANY multiplier.
Priming at 9*320 now :banana:
hmmm
I also use P4P800 and P4P800SE and I can bench about 9x 320 MHz (air)
but without disabled PAT ;)

It is a memory/chipset/Bios problem, not CPU ...Quote:

anyone knows what the hell is going on? ( it's nog my mem, got divider on it ). Or is this just my max? Temps are a bit high so water is going on it tomorrow or tonight, maybe then I will get higher.
( posted this in another topic 2 )
I was about to post my problem, which is very similars to yours.Quote:

I figure if I can do 215*12, and could easily to 225*11 or 225*9. But I can't.
I've bump up vCore from 1.5 to 1.6, and still nothing.
I can cold boot into windows at 210 day and night. I use clockgen to OC from there.
So does this mean the mobo is having issues? I know RAM is fine.. it is doing 280 right now.
Any insight or suggestions would greatly be appreciated.

SAD, No, I suspect either the chip itself (almost definately) or the adapters (very slim chance).
2860mhz (10*286) 1.55v, 1.47v real under load, stock aircooling.

:banana:
I hope I can get it to run spi 1m at 3ghz :woot:
Hmm.. need to get another chip then :)Quote:

It's probably the chip. You are sure that PAT is fully disabled?
Manged to get my 730 there on waterQuote:

I can see yours takes a little higher vcore, that makes it harder for me already.
I need a more stable OS than windows xp. My Dothan causes system services to crash while it is happily running prime95 small FFT's, this is NOT my motherboard or memory and I'm 100% sure about that. I'm going to try win2k pro but I will use server 2003 in some time.

That max with 1.6v set. rem that it droops to 1.51v under load too :(Quote:

I think with win2003 and tweaks I could maybe pull a 24sec at 3GHz, but I leave that to the serious benchers :)
Stock air, Windows XP pro, 1,6v in bios for a little more stability over 1,55v.
PAT: DISABLED, I have to fix this problem first. I'll try some 13* mp 1:1 2-2-2-5 2,9ghz runs today.

25 secs on stock air, now how's that :banana: :banana: :banana:
actually it's 26 :) But nice!
the original superpi would show 25sec ;)Quote:

i got lower number mby because i had 1 gig ram..
I need win2k or server 2003 and PAT enabled but PAT is killing my overclock somehow.
How do you turn off pat in bios? I set performace mode on standard but pat is on ...
Boot at 201mhz fsb or higher instead of 200mhz. CPU-Z shows it wrong. You have to take a look at what everest says. Enabling or disabling PAT with 865 tweaker doesn't work.
*This is with the 865PE chipset. I think PAT keeps enabled with the 875 chipset above 200mhz fsb. I don't know how to turn if off really. I think it is best to set it at "standard" and then use everest to read if it's on of off.
tweaker works... If I say pat disabled it's not shown in everest and if I say enabled it says pat enabled...
Now I'm stuck @:
223*12
240*11
242*10
260*9
Anyone knows how 2 get higher?
This is exactly where I was hitting a wall with PAT enabled.
I would flash a P4P800-SE bios in it if I were you so you are 100% sure that PAT is disabled above 200mhz fsb. You can always flash back if it doesn't work any better.
Hmmz will try that, do I have 2 disable bootblock in order 2 flash?Quote:

Ask him, he knows.
