With my Q9450 and 8GB of RAM, I am able to post at 501 FSB with an 8x multi. I could probably get stable if I dropped to 7x multi, but no point, slightly less CPU speed, harder to get stable, and lower RAM speed over 451 FSB with 8x multi.

Run a little prime between testing...
Man, i have tried all of your settings to no avail.... Maybe i need a lower vid proc.... I bought a "oem" proc, and lapped it, shoulda wrote the damn numbers down.....:shakes:
run 4 instances of NCI memtest for windows, set each version to use 1700mb of ram and see if it will do 300% coverage. If it passes that it will pass anything. If you want really brutal run CoreDamage at the same time to catch any cycles memtest leaves unused.
It's not a Vid. thing, its an fsb thing; your processor must be capable of it, your motherboard/chipset must also be capable of it. I have a Q6600 here with a Vid. of 3.125v that does 500fsb. So I can confidently say it has nothing to do with the Vid.Quote:

Ok, was testing with new settings... vfsb=1.40v, Vnb=1.61v..... Will give HCI memtest a shot....Quote:

Everest bandwidth test is with ram untweaked... vnb=1.6v (as reported by everest); vfsb=1.394v. vdimm=1.80v (bios set), 1.88v actual.
I'll be playing with some ram tweaks to see if I can maintain stability.
Maybe this threat is dead but im still asking anyway;
I managed to get my Bios stable at 7*572 but cant get 470+*9 stress-stable.
cpu- and NBTemps are under 42 degrees stressed for hours (4.1ghz)
Ive read all the manuals for oc maximus but coming from AMD doesnt make it easy.
I used Zuckers2k's settings (+little ram adjustment) to get to 7*572 in bios stable.
Can someone please post E8400 E0 settings for 500+FSB? I know this isn't the oc-my-rig-for-me-thread but ive bin tweaking for weeks now. :shakes:
I have an old E8400 setup its a C1 chip but it should be a good place to start.Quote:

wow, thanks for the quick response.
Im gonna flsah it into rampage, can i just get the latest bios or should i get 0403?
I just flashed my mobo to Rampage Formula. This gives me a lot more setting which just makes it harder for me to set them correctly :confused:
I flashed it to rampage, its a bit more complicated now but i get most of the settings and got 8.5*500 stress stable for 18+ minutes:
Managed to get Orthos small FFT's stress test stable for 18+min (stopped the test, all temps stay below 42degrees C)
My settings for that are:
Ai Overclock Tuner : Manual
CPU Ratio Control : Manual
- Ratio CMOS Setting : 8.5 :)
FSB Frequency : 500 :)
FSB Strap to North Bridge : 333
PCI-E Frequency: 100
DRAM Frequency: DDR2-1002
DRAM Command Rate : 2T
DRAM Timing Control: Manual
CAS# Latency : 5
RAS# to CAS# Delay : 5
RAS# Precharge : 5
RAS# ActivateTime : 18
RAS# to RAS# Delay : AUTO
Row Refresh Cycle Time : AUTO
Write Recovery Time : AUTO

Ai Clock Twister : lighter
Transaction Booster : auto (0-30 dont get this??)
CPU Voltage : AUTO //reads in BIOS/cpuz/cpuid: 1.304v
CPU PLL Voltage : 1.50 // 1.58v
North Bridge Voltage : 1. 51 // 1.51v
DRAM Voltage : AUTO // 2.1v
FSB Termination Voltage : 1.6// 1.5v
South Bridge Voltage : AUTO

DDR2 Channel A REF Voltage : AUTO
DDR2 Channel B REF Voltage : AUTO

SB 1.5V Voltage : AUTO
CPU Spread Spectrum : Disabled
PCIE Spread Spectrum : Disabled
Tried 3 hours to get 500*9 working but could not boot windows nomatter what, while 520*8.5 is able to boot vista and make screens but not stress the system...
Anyone know why i cant go higher/ what im doing wrong here?

Hi zucker , you sure know your q6600's , have you kept count of how many you have tested ?
:up:
Hey Aussie mate, no :) I lost count a long time ago. How's that L737B holding up?
Is this so? Why can't it be set manually in bios? The only way I could get a decent OC on the Maximus formula bios was to set this to 55 with 8gb of RAM.Quote:

You answered your own question; the settings are in increments of 5, so, 40,45,50,55. The stock TRFC (SPD) for the G.Skills is 52. If you set TRFC to AUTO, the bios will pick up the 52.Quote:

If you mean 45nm quad @ 8.5x500fsb, PL8, high vtt (up to 1.70v), high vnb (1.65-1.75). If you drop the multi to say 7, you'd need lesser volts. Keep cpupll pinned at 1.50v.
Damn my e-peen is gone...
My Q6600 wont even post at 460FSB. walls at 455 :(
Maximus Formula SE flashed to Rampage 0601 bios. Tried your settings, no go. im also using 8GB of G.Skill ram, but it wouldnt work when i had 4GB either.
FPO/Batch is L726A880
I'll try playing with gtl/vtt; remember, higher gtl = lower vtt, and vice versa. Some Q6600s tend to love higher gtls. Also try to keep your NB temps cool.Quote:

I have a 80mm fan that cools the top of my GTX280 and it aims right at the copper heatsink. i took off the rubber plug things and opened up the holes for even MORE air.
Im at 0.67x on the CPU GTL REF..
Cant go any higher :mad:
OH and btw! i had a E8400 before this chip in this board, ran 460x8.5 just fine for 3.93 i believe. i had 4GB of ram at the time, but the 460 ran fine.
I tried pulling 2 sticks of ram out and trying 460, doesnt work either
