Overclocking a Q6600 at 3.6 GHz with 800MHz ram

wel the topic title says it

im so far at 3 GHz but cant get stable any further

right now my FSB is at 333 x 9
Vcore at 1.125 this is running prime stable

but when i try 3.6 fsb 400 x 9 Dram Freq at 801 MHz Vcore at 1.35/1.45
timings 6-6-6-18
its unstable my cpu is fine temprature is fine(50/60 Celsius) i think its my ram screwing up cause every time i try to run prime it emmediatly crashes at the 1024k torture tests i also tried SB and NB at 1.4v FSB termination at 1.5
but it wouldent differ
somehow my ram stay's stable for the longest time when i have timings at
4-4-3-15
now i have seen many people having problems with this ram

my system is
Mobo: P5Q-E
CPU: Q6600 G0
RAM: OCZ ReaperX HPC OCZ2RPX800EB2G
cooling: Corsair H50
GPU: Nvidia Geforce 8600
PSU: OCZ StealthXstream 600Watt

so my CPU is not the problem (i think) my ram keeps screwing up

this is what i tried so far
FSb 400
Multiply x9
Vcore 1.35/1.45
Dram Freq 801 MHz
SB and NB at 1.4V
FSB Terminator 1.5V
Timings 6-6-6-18 and 5-5-5-15 and 4-4-3-18
DRAMv 2.1

this is unstable so if any one hase suggestions please post them im out of ideas

Depending on your VID, and if your Q6600 is newer, there's a good chance you're going to need more than 1.45v to get 3.6 stable. Some newer ones won't even do 3.6.

Keep your timings loose when OC'ing. Once you get stable then try to tighten them.
Make sure you only make one change at a time when OC'ing and write down each change so you know what works and what doesn't.
Q6600's usually take a lot of vcore so crank her up.

okey so what is a safe Vcore to use the q6600 at 3.6

i dont want it killed

i even tried Vcore 1.5 that wasnt enough if i go any higher ill end up destroying the cpu

and what is loose timings for my ram 6-6-6-18? i have no clue how timings work tbh

what Vcore do u suggest i put it on

Going higher won't kill the CPU. 1.55, while a bit high, is fine. I ran one of mine up around there for a long time on air cooling and it never had problems.

Yes loose timings would be 6-6-6-18.

k so this is what ill do next

Vcore 1.55
Dram Freq 801 MHZ
Timings 6-6-6-18
DRAM V 2.1
NB and SB 1.4
ill post if it is stable

wel Vcore at 1.55 doesnt work

it crashes trying to start up vista i really think its my RAM
any one alse having problem overclocking with this ram??

could some one give me his settings so i can try it out

it doesnt even work when i set multiplyer at x8 and FSB at 400 ore 378

i dont know how new new is i got my Q6600 2 years ago

Have you tried to stress test at stock settings? Maybe there is a hardware problem. Might want to run memtest at stock and see what you get.

what this mem is new i just bought it T-T ill test it with memtest

i already overclocked my stuff with fsb 333 and used prime it runs fine i tested it for 2 hours

Your FSB Termination voltage is way too high man. I'm running 475FSB with 1.3 FSBv.

Fill in your sig rig specs so we can get an easier view of your components. In the User CP.

Ram Timings
CAS Latency Time, This number dictates the number of clock cycles that pass before data can be read or written to where its stored in a column address, typically the first number.

DRAM RAS #, this number represents the clock cycles it takes between finding the row of a location in memory and finding the colunm. The lower the number the faster it takes place, typically the second number.

DRAM RAS # Precharge, this is how long it takes memory to stop accessing one row,build up a charge,and access another, typically the third number. Lower number is faster.

Precharge Delay or tRAS, this number represents the minimum number of cycles that pass between an active and precharge command. The lower the number the faster the performance, represented by the last and highest of the four.

CMD is the delay, in clock cycles, from when a memory chip is selected and when the first active command can be sent. A 1T command rate offers better performance than 2T but 2T is more stable.

k i tested the ram with memtest 0 errors found so the memmorry is just fine

any one got any ideas to why my stuff wont run when FSB is on 400 and Vcore 1.55 timings
6-6-6-18

Like someone else pointed out try changing your term, and or NB volts. One at a time of course.

wel i have tried even updating my bios

wierdest thing is my pc stay's stable when i put timings on 4-4-3-10 :s
it was stable for 5 mins and it actually started windows vista then it crashed

and by one at a time u mean if one doesnt work try the other but reset the one u jest edited

I THINK I FOUND THE PROBLEM!!!!!!!

DRAM Voltage hade to put at 2.2 instead of 2.1 cause its running at 801MHz its need a little more voltage!!
im running prime now and its not failing at the ram tests ^-^

so how do i earn the status of over clocking a Q6600 at 3.6 GHz with a Corsair H50

I think you stuck with it,posted your validation,a 1.2ghz OC (stock was 2.4?) surely earns a +rep

You know that ddr2 must be run at 1.8 )))) and if you have orclocked RAM crom ocz or corsair it will be 2.1-2.3 ...... but your situaion is interesting..... you push your timing high, means you make it slower, and the voltage don't have to be so high. imho/
