I don't know how you guys are running the mega fsb's over 400 without losing 16x PCI (it changes to 1x). At least that's what happens when I try to hit 400 fsb. Kinda defeats the whole deal if you plan on using a good vid card in games.

How do i know what my pci-e is running at? How do I check?
Open cpuz, Mainboard tab.
If I put my NB Vcore to anything LESS then 1.55 I have the 1x issue.Quote:

Rig and voltages:
P5B Deluxe w/ 0804 bios
CPU: E6600 @ 8x420 (3.36ghz)
RAM: Crucial Ballistix PC2-8000, running at 2.15V, 1:1, 4-4-4-12
HSF: Scythe Ninja Plus (original, with the backplate)
--the Scythe fan is on the RAM side blowing through the HSF
CPU Vcore: 1.425 (probe reports 1.38 in windows)
FSB Termination: 1.3V
NB: 1.45V
SB: 1.6V
ICH: 1.215V
Anyone have any ideas? I'd like to push further but these temps already scare the hell out of me.
I have the exact opposite problem. Anything over 1.55 and it drops to 1x. I have set the bios at 1.45 and then use my VR(voltmod) to raise it to 1.6 and it still drops to 1x so it is either the bios detects the voltage and drops it due a poor bios code or it is a design flaw.Quote:

Anyone have any idea why in windows when I go to the system properties it reports me as running 4.3ghz when I'm only running at 3.37?
System assumes you're running at max/native multiplier when you're not.Quote:

I'm using the Arctic silver 5 stuff...is this stuff good or should I be using something else? Possibly I need to take my Tuniq Tower off...clean it and the cpu and reconnect it... think that might help? What could possibly be the culprit and also what should a normal/decent idle speed be with a e6600@ 3.37 with a tuniq Tower 120 and cpu core volt of 1.4?
Same thing here on NB voltage relating to the 1x issue. If I set anything MORE than 1.45 volts, I get the 1x. If I set it to 1.45 or less, computer won't boot (at anything at or above 400 fsb. So I'm stuck. It's why to get my goal of 3.2 gigs (which I'm happy as a clam about), I had to settle for 9x356. For my system it's the definite sweet spot.
With 910 bios I am currently able to run my northbridge voltage at 1.57 with my vmod before the 1x problem kicks in. I have found that when the pc boots at 1x I will pull the power plug for 10 secoonds and then turn the pc back on it will boot at 16x.
That's just not acceptable to me. I had that same issue at 401. Didn't take me long to say, "enough of this". That just cannot be a healthy condition for the system.Quote:

I got to hand it to you guys that have been able to get a 400+ FSB that is STABLE. I gave it my system's best shot but couldn't get it. I think I wanted over 400 just to say, "I could" but in all reality my 9x356 @ 3.2 gig is still above Intel's $1000 processor so I can't complain. :)
geez!!! i guess i must be lucky then.
i run 8 x 475 with 1.65 volts on the NB and don't lose 16x pci-e frequency.
Just what i need to know. Cheers, :)Quote:

You may need a stick of ram that will boot at low voltage, go into bios and increase the voltage to watever your power sticks require then shut off the power supply and add the correct ram modules. You have no listed your system specs so I cant really help. This is what I am assuming since you've reset the bios.Quote:

nope these are D9's stock speeds of 533 and vdimm 1.8v
Yes ive reset the bios and still no go.. looks like its gonna get RMA'ed
tried both sticks... it still does the same thing even with out any sticks in it...
specs :
Xeon 3040
Asus P5B-d
2gb D9's tested @ 900Mhz 1:1, 1200mhz @ 4:5
8800GTs
xfinity 500w (i know shut up :P)

nope PSU reads good. This Ultra has been a great PSU and has POwered a overclocked 9750Gx2 and a presler 930 @4.5.. I dont care what ppl say about ultra's the Xfinity line is a good PSU and Ive tested this one and its still solid.
EDIT i think i found what died... the vcore IC didnt look like that before >: )

Any thoughts on my last post guys?
Heres a quick question, will having static read on my memory set to "faster" will it enhance memory performance or is it better left off?
I really need to lap this CPU. This Ballistix RAM is incredible:
E6600 @ 3.2 (401x8) 1.4vcore bios, 1.36 probe idle, 1.34 load
DDR2-8000 Ballistix rated 5-5-5-15 500MhZ @ 2.2V, running 4-4-4-12 at 500MhZ @ 2.25V (why is there no 2.2V option in my BIOS?)
My temps still suck on the CPU, though. :(

I'm having the same problem... (as is MRT2 I see). Similar setup to DCarez but with a 6700/Corsair/Zalman9500 and only oc'd to the same point 3.2ghz (which should be less stressed than the 6600 put to the same place). Really bummed on this as it seems way too hot! I'm going to lap the cpu tonight and give it another try.Quote:
