thats a good chip!
i just got a L739B879.. yet to test it. didnt wanna take the risk with a l740b i could have chosen.. would preferr l744b - my last one did 5.6 3d06.

You really need to put me in touch with your sources NR, how many QX chips in the last 2 months is that? About 6+?
well just bought a new qx9650, not tested yet but at least it has a lower vid (1,135v l748b) than my old one. hope it will clock better than my last one.
maybe a silly question...but does anyone know the real tj.max of the qx series? coretemp shows 105°c and realtemp 95°c or is it just a reading error.
Man, I'm getting insanely high temps on mine.
I've remounted several times and at 4.0 GHz with 1.4v it's getting up to 80!
This is with a nozzled Fuzion with NB and Mosfets in the loop on a PA120.2 with 4 Scythe S-FLEX SFF21E.
Could it be just too much for my loop? Or is this an extra hot chip?
still had no time to oc it since i'm still trying to solve my freeze prob with the quad 9800gx2 that so f.... annoying.
Intel's spec. finder show the real tj. max for the CPU ;)
But I'm amazed that my ship did 5.8Ghz, when i changed MB today I saw that it was a 40A not B, that one we know to be the worst chip out there :(
But my waffer number is 915 and VID is 1.135v :S
With the Week39 I'm testing right now under ss I finally seem to have it stable at 435x10 with Vcore 1.49V (set 1.475V) under load and VTT 1.36-1.38 (set 1.35V), NB 1.57V (set 1.604V) and GTLs on this DFI LP X38 at 75 75 80.
Last night I was trying to find the highest stable FSB (multi at 6x) with the VTT set to 1.35V and adjusting the GTLs. 440MHz just would not work. The longest I got OCCT to run was 14mins.
440 wanted my previous 1.438V VTT to be stable. The max FSB I could possibly get stable was 455MHz but it required a VTT of 1.603V which I felt was a bit suicidal.
Next I'll try to lower the FSB and raise the multi to 10,5 and see if I can get the CPU speed stable a bit higher! ;)
Just a bit annoying that this chip boots all the way up to 5GHz but to get it stable I have to back off a whole 650MHz... :mad:
anyone know anything about the L746B? iv got one lying around, havnt opened it yet tho (stuck with a 650i mobo atm =[).
I personally got it handed to me by an intel personall so it better be good lol!

hello hipro5. my name is Spiros and i'm from Igoumenitsa(Greece). i have this problem. i have this system: mobo:Asus P5E3 Premium with X48 chipset, CPU Intel QX9650(batch L744B156) and memory: Corsair Dominator DDR3 at 1800Mhz. i don't want to make something extreme with this. i only want to put the memory to play at 1800mhz. so in bios i put
manual,
multiplier to 7.0,
FSB Strap to Northbridge 400,
FSB at 450,
PCI-E:100,
the memory 1800,
timings : 7,7,7,20,
command rate: 2N
and memory voltage 2.0V
all the memory settings are the stock settings.
all the other settings i leave them to auto.
also the DRAM Static..and DRAM Dynamic...i put them to disabled and load line calibration i checked to both normal and performance and CPU Spread Spectrum and PCIE Spread Spectrum also disabled. so i have the CPU at 3.15GH and memory at 1800Mhz.
Now the problem is that the system is not stable.
if i run CPU Stability Test after 1-2 minutes says problem in TPrime module. also in Prime95 multicore after a while fails in 2 cores.
please can you advice me what settings may i put to make my system stable?
also i noticed in Real Temp that from cpu the core 1 sensor is stuck at 40c always.only if i overclock to 4Gh the sensor starts to work. in my system i have a watercooling solution from Thermaltake. but the cpu temp is idle at 45c. is it right this temp for this cpu? also if i underclock the temp stays at 45c. i think something is wrong here. also i remember that the 3 last numbers of the stepping/wafers is 778. i have bad luck with my cpu? should i RMA it?
please my friend help me with this.
be well my friend. Spiros!!!
It is most likely unstable because to get 450fsb from a quad you normally need to spend time tweaking.
Here are my results with QX9650. I am debating going upto 1.6 V to see how I can take this chip. What do you guys think about the temperatures I am getting with the water cooling. Do they seem reasonable ? All temperatures are recorder at 25 deg C Room Temperature.
T M please, can you advice me what settings can i put, or with what settings can i test to have stable my system?
this is what i get from CPU stability test and real temp:
