------------------------------------------------------------------------------------------------------------------------------------

I can't have a stable system with more than (9x300) 2.7 Ghz, FSB Hole on my motherboard is 320 to 336.

The funny thing is that i can boot at 3.240 Ghz (9x360) but computer reboot during windows boot.

I think it's just a bios configuration problem, but i don't find where the problem is.

If somebody can help.

Thx by advance

Nice Config... It's not a cooling problem or lack of power for sure lol! 9 Fans and 1KW PSU.....

You have also top-notch parts that are even a little bit Overkill :p

So you are French Speaking (Ma, en,? , tout, r?el), you can PM me (OR EMAIL) if you wish, I'm a Quebequer.

Talking in French won't be permitted on the forums.

[BouRRin]

Thx a lot, i can speak english it's not the problem, i use (Ma, en,? , tout, r?el) 'cause it's a copy of a french forum post ^^

But if u prefer mail or PM i can do it too ^^.

[NienorGT]

It's as you wish if you prefer talk French PM.

You have XP or Vista?

You have 4GB, so you use x64? Or you stay in 32Bits and have access to only 3.25GB?

You have tried with only 1 8800GTX at stock speeds?

[BouRRin]

I'm using Vista 32 + SP1

I Tried with Vista 64 but lot of problems with games so i prefer 32 Bit even if i "only" use 3.25 Go.

I tried with only one GTX at stock and with only 2 Go RAM, but problem still the same.

Type "SystemPropertiesAdvanced" in the start menu then hit enter.

Open Settings of "Startup and Recovery"

Uncheck "Automatically Restart" (if already unchecked, don't check it and post back here)

Reboot, overclock to an "unstable" setting and see if it make a blue screen.

[Berserk87]

im using a Q6600 "Go" as well, and i have read/experienced the same thing.

im sitting at 333MHz FSB right now, and running orthos to check stability.

from what i read theres a fsb hole between 333-400Mhz.

ill give you the specs im using

CPU is at 3Ghz using - X9 multiplyer and a FSB speed of 333Mhz.

timings - 5-5-5-15 @ 2.2V and running at 400Mhz

DDR2 - 800

Ok i'll try it tonight ^^.

Berserk87 :

I had already try it...

With this spec my computer boot with a black screen and "overclocking failed" after the second boot.

But Thx for your help.

[Berserk87]

mine had a lot of black screen as well.

are you sure you tried all of those settings exactly?

because pretty much, if i change anything there, ill get black screen as well.

try these.

the last ones i posted got bsod after running orthos for an hour.

5-5-5-15 @ 2.225V

330Mhz FSB

memory is at DDR-790 i think - 400Mhz.

ran orthos for 3 hours, stable.

and this is the best OC ive gotten.

[BouRRin]

Hi there,

Not stable for me ...

Don't know where the problem is, because i can boot at 3.26 Ghz (9x460) but pc reboot at the vista login screen.

[Berserk87]

what kinda of ram are you using?

so far it looks like your motherboards limitations with something.

what i posted above, im actually going to go a bit lower now, because my temps are getting too high on load.

[BouRRin]

My Memory is 2x Dual Kingston HyperX 2 Go DDR2-SDRAM PC8500 CL5 - KHX8500D2K2/2G.

[Berserk87]

that ram should be able to handle more than that...

so i guess your mobo is limiting your OC, or your bios isnt configured properly.

i would rma your mobo if you still can, see if you can get a gigabyte mobo, they're supposed to be able to OC easily and stable.

[Berserk87]

ok, i think i really got it this time :p

fsb is at 330Mhz, Ram is at 2.2V, and i left the timings to auto.

im still getting 17s in Super Pi, but with the lower timings it looks like im getting better stability.

running orthos right now, let ya know in 4 hours.

[Berserk87]

6 hours stable.

try using those.

[Berserk87]

arg! edit times.

im at 8 hours stable now.

update:

9 hours 30 minutes.

I usually stop after 8 hours stable. Maybe a few more hours if I forget about it hahaha.
