hi all ,
first here is my config :
Intel Core 2 Quad Q9550 2.83 GHz
Cpu Cooler : Cooler master Hyper 212x .
-ASUS P5Q3 DELUXE Rev 1.xx ( P5Q3 Deluxe/WiFi-AP )
-Chipset : -Intel P45/P43/G45/G43
-Ram : 2x2 Go (4go) Corsair xms3 platinum serie , 1333mhz cl9 ( 9-9-9-24 )
+ 2 new sticks (2x2gb) they have exactly the same brand, Model , CL , frequency and timing ( cl9 , 1333mhz , 9-9-9-24 ) etc.. [ part of the probleme ]
graphics : Gigabyte Gtx 750ti
Psu : Enermax Liberty 500w fully modular .

And Guy's It's A long Post so Please, Please bear with me while I explain this . because i could really use your Help !! .
---------------------------------------------------------------------------------
ok guy's , long story short , upgraded new cooler , new Gpu from 4870 to 750ti and added 2 stick of ram (2x2gb) i went from 4gb to 8gb so it's a total of 4stick installed ( Mobo don't recognize the 4Gb sticks ).
anway before we talk about the overclocking i just want to point out the ram stick's probleme . so after i added the 2 of them ( All pictures will be bellow ) the computer didn't want to post not even to the bios , so i tested one of them on another computer and it worked just fine then i added another stick from the old 2 stick's ont that another same computer but an error pompt up i don't remember exactly but it was something about frequency or incompatibility so i guessed that the new ram's are maybe not compatible with the old ones in timing etc.. even though i checked the sticker on them and it say's 1333mhz 9-9-9-24 just like the old ones i have . so after trying few things i removed the new rams and left the old ones , went to the the bios set the Dram frequency to 1066mhz , and it worked so the Dram frequency now in cpu-z is 534mhz instead of 666mhz so i guess in down-clocked them .
i just wanted to know , is there any solution that i can do to make them run at their full speed , maybe by changing the timing but i have no idea how to do that so a little help will be appreciated ^^ , i'll post pictures of my mobo bios down in this post so you can have an idea .

-------------------------------------------------------------------------------------------
ok now for the overclocking thing ,
i did manage to get the cpu from stock 2.8ghz to 3.4ghz with allmost same temps as on stock frequency which is nice ,, so here's what i did :

- Cpu Ratio : Auto [ because it can't go over 8.5 so that will be the same as Auto .
-Fsb frequency : 400
-Pcie Frequency : 100
-Dram frequency : 801mhz [ which is the first option from the available List ]
-Cpu Voltage : 1.2 [ that appear 1.184 On Cpu-z ]
-Dram voltage : 1.5 [ just like it is mentionned on the Sticker xD ]

Then :

-Cpu ratio setting : Auto
C1E Support : Disabled
-Max Cpuid Value Limit : Disabled
-Intel (R) Virtualisation Tech : Enabled
-Cpu TM Function : Disabled
-Excute Disable Bit : Enable
-Intel (R) Speedstep (TM) Tech : Enabled

Ps : Am i missing something or is there any other settings i can change etc.. ?

saved it and reboot , pc run's fine , i didn't run some stress tests or something but i did play Gta v for a brief Moment, temps were fine and cpu usage too etc.. but what bugged me is that now ( as the picture show bellow ) the dram frequency in cpu-z is only 400mhz , but has low latency .. ( look the picture ) does that mean that the ram's are far less more powerful than they are originally because they are down in frequency ? or does the low timing compared to the old one compensate for that [ fSB dRAM : 1:1 ] .
am really confused guy's am not that much of a knower let's say in these things , so i try to do my best , resarching learning etc.. before posting for help on a forum because i only do it as a last resort .

so i hope that i made this Post very clear and gave all the details possible so that you guy's can understand The probleme Am dealing with and help me find a solution .
Thank you

Its always a gamble with OCing and voltages. That said , its been to long fore to be sure of voltage I used in my Core 2 days with E6600, Q6600, ect. 1.3v does seem fine I'd think, as I used 1.35 for my 45nm Core i7 920 a couple years and had no problem. Chip still running today, though back at stock as it was sold. Temps look fine as well. I think your set, really. There may be a few minor tweaks in BIOS, but likely minimal gain from where you're at. For testing OC, i'd try Prime95, Memtest, IBT, some Sisoft Sandra benches, 3dmark, and more casual use to be sure.
You can try using the XMP profiles to adjust to their full speed, this should in theory set the timings/voltages for the modules automatically. However, you can manually input them as well. Also, I'm a bit rusty going back this far, but your platform uses the FSB to get it's clockspeed. Your FSB x Multiplier are creating your CPU speed. This FSB though is also used for RAM speed. There are FSB/DRAM dividers which is what you're looking at when you're trying to change the RAM speed in the BIOS. What happens though is that since your OCing your FSB, the frequency of the DRAM won't match exactly as intended. For example, in your last pic, you see that your at 534 roughtly DRAM frequency, which is 1066 using DDR speed. This is using 5/8 ratio. This is also using stock 333. If you did nothing other than increase your FSB to 400 like you're using for OC, your RAM would automatically try to run at 1280Mhz. Since your OCing your CPU, you may have to figure out what your speed will be from looking at BIOS options when inputting 400 FSB before actually save/exit from BIOS. It may give you a preview of the actual speed it will be trying to run. For your question about higher speed and higher latency vs. lower speed lower latency, this is the never ending debate. It seems to boil down to benchmarks and applications that prefer one or the other and which would actually be "faster" in real-world use.

Also, even though you tried to match both RAM kits with speed, voltages, and timings. This doesn't always work. Sometimes separate kits don't play nice together in certain boards. I've had this happen myself in a 680i SLI motherboard I had years back.

ok so after reading your answer i said well the hell why not try to pump that cpu to 4ghz anyway , and so after several tries to get the lowest voltage minimum i sat on 1.3v ( 1.288 on cpu-z ) , so with the old ram stick's alonen i was able to get them to 666mhz or 640mhz depending on the choices giving me by the Dram frequency list , because that list changes each time you change the Fsb frequency .
but then i discovered that when adding the new rams with the old ones even with 1.6v the computer will not even post and after several tries by removing rams changing settings etc.. then plug them again i noticed that when all the ram stick's ( all 4 ) are plugged-in ,their frequency can't go above 600mhz in cpu-z which means what ever Dram frequency you're gonna choose in the bios ( depending on the fsb ) that Dram frequency Must not surpass 600mhz when divided by 2 . so on a fsb of 471 ( in my case 4ghz ) the max Dram frequency that could get me to 600mhz or close was 1181/2=590mhz . and so the computer could post or else ( higher ) it will not even if i add some voltes to the rams ( weird ) but hey 600mhz or 590mhz are not far from 666mhz . i guess there is not that much of a difference if none on the performance level .
so now i just want to know if there is a good benchmarking programs that i can run to test the cpu stability and for how long i must run them .
and is 1.3v is safe for a 45mm q9550? my temps idle are 36-37c over the stock that was 32-34c . and here are 2 pictures from the overclock .

thank you .

Edit :
So after runing some prime95 and gta 5 the cpu wasn't stable at 4gh on 1.3v and 1.33v i didn't want to raise the voltage and push it more than that and shorten it's lifespan so i decreased it to 1.3v (which is 1.296 or 1.288 in cpu-z i think ) and downclocked the Fsb to 450 so now am sitting on a 3.8gh , i don't think that there is mch of a gain between 3.8gh and 4gh if allmost none . and i think it's stable after 30min of prime95 stress test , temps never reached above 62c . so the question is ,
-do i need to tweak some other settings maybe in the bios ?
-is 1.3 (1.296) safe for the 45mm q9550 with thoes temps ?

thanks

ok , thank you for your answer maybe i'll take down the voltage a little bit and see if it's still stable bellow 1.3v, as for a last question now that i think i have it stable i know am being obsessed with this but when playing games like gta 5 league of legends Mgs5 firewatch etc.. the temps allmost never reach above 54c
is that a fine temp while gaming ?
yhank you so much .

Yep i i think i don't have to worry then , cause in gaming temps are always on 50-51c and sometimes 54c but never above that and in casual/normal use its 34c-40c (max) , so i think am fine , thank you for your help ^^
