QUAD qx9650 @ FSB 450 Mhz is it safe?

[antonka]

I just worry about fsb termination voltage. What is the safe value for it??

 

[antonka]

Anyhow pc crashes on that multi. Does anyone know what to do? When I am stable at this speed may be I could try higher but now I am totally unstable even @ 3,16---

try uping your multi to 9+

And LOWERing the FSB.

i dont understand why your ramping FSB for.

and heavens who told you fsb term was dependant on multiplier?

you got it the other way around. Higher FSB = more fsb termination.


People grab QX's so they can be on a low fsb, and high multi. Not the other way around.

Hi,

If I down FSB Voltage system becomes unstable. Or if I rise multiplier would it be more stable? I doubt so...

Possible reasons why your PC crashes:
1. Your QX9650 cannot run at such high FSB
2. Your P5E34 Deluxe is having problems running at that speed
3. You didn't give enough FSB Termination voltage... but then again... yours is already at 1.4V... pretty much at the safe value limit for 45nm CPUs.

Isn't there any other DDR3 mobo user here? I mean I've said this before;

Can't you use the Memory Divider like on DDR2? Say you have the FSB at 400MHz (1600MHz Quad pumped), you can use 3:4 divider and have the RAM at 533MHz (1066MHz Dual pumped). That's my understanding.

That way you don't need to drive your FSB up the wall just to have your RAM running at 1800MHz.

If you set the FSB Frequency back to 400Mhz, save & exit BIOS, then go back into the BIOS, select the DRAM Frequency and press Enter, don't you get an option for 1800MHz? Maybe you haven't chosen to set the DRAM settings manually? I'm just not sure because I never had a DDR3 mobo, not that it will make anything faster other than benchmarks.

And do you really need that much FSB Termination voltage to run at 450MHz FSB? I don't know if I'm lucky or not but at 450MHz FSB, mine is rock stable with just 1.3V FSB Termination voltage in BIOS.

Hi ShadowFlarex. Thanks I ll give a try when back home... But I think I tested it before and I could not choose 1800 Mhz @ 400 FSB

It seems you've gone out and spent thousands of dollars on high end components for no real reason other than because you can. A good overclocker can build something for a few hundred dollars that will outperform a stock high end system. That's why these people are frustrated that you said you own this stuff but don't want to overclock it. It's like buying a Ferrari to keep in your living room.

Hi,

Since I only started that stuff I do not know muc abut things. Mayhap I wil bit OC in the future but now I just need system to be stable. Crysis crashed yesterday..... Just f@*$§ked up system was too expensive and still not working properly

@ Antonka:

Try the following settings:

AI Overclock: Manual
CPU Control: Manual
FSB Frequency: 450 MHz
PCIE Frequency: AUTO
DRAM Frequency: DDR3-1800 MHz
DRAM Command Rate: 2T/2N
DRAM Timings Control: Manual
CAS# Latency:___________8
RAS# to CAS# Delay:______8
RAS# Precharge:__________8
RAS# Activate to Precharge:24
DRAM Static Read Control: Disabled
DRAM Dynamic Write Control: Disabled
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
CPU Voltage:__________1.40V
CPU PLL Voltage:_______1.35v
DRAM Voltage:_________1.80V
FSB Termination Voltage:_1.45V
North Bridge Voltage:____1.55V

Multiplier = 7

* * * WHAT KIND OF COOLING DO YOU HAVE? * * *

Can you change any other settings?

Like gtlref lanes?
tWRC, tREF, etc.?

Show me all your BIOS settings.

You can get that rig stable if you have the right settings, it will just take time to find them.

If not, you may have a bad mobo, or bad RAM dimm, or insufficient Power supply. But let's try to get it stable first.

I have same RAM and cpu, so I think I can help.

 

[antonka]

Hi,

My settings are already the same except of
CPU, CPU PLL (AUTO) and
FSB Termination Voltage:_1.42V
I heard that is critical and dangerous thing and could kill 45nmm CPU.
NB I even put higher to 1,57. Still BSOD at Assassin Creed.
WHat you think?

 

[GundamF91]

Do not use AUTO for CPU voltage. Use 1.4v as suggested and no higher until you have good cooling. By the way, what temperature are you getting?

You want to isolate the fault here, and first set everything as manual and then slowly change figures. AUTO setting does not work well if you are doing custom config outside of basic design parameters. It looks like your QX9650 or the Asus P5E34, or combinations of them, are not able to run reliably at 450 FSB. You'll only be able to figure out which one is at fault by testing piece by piece. Another thing to consider is your DDR3 quality. Have you been able to test it with Mem86+ for problems.

This has to be a joke there is no way this guy bought a setup like this.

He knows enough to set the Termination voltage but leaves the CPU on auto?!? 450 fsb x 7 on a QX? This is fake.

 

[BlueAcolyte]

Ok, I would suggest going back to start and unscrewing up everything so far. Then we can start again.

That means 9 x 333 FSB, default voltages, make it stable at stock then overclock.

 

[antonka]

Hi,

So I was able to run Mem86+ successfully with CPU 1.4, NB 1.51, FSB termination 1.4, but then after Windows started got BSOD again. I am really a dumb with OC so please describe step by step what shall I do to make the system stable. How do I check what causes the problem??
I fugured it out that I can get stability by either rising NB or FSB termination but how find a ballance??

I also run OCCT but it ended up with piggy error.
I noticed that although I set CPU to 1.4 it falled down to 1.24 V after some time... Why is that??

Thanks in advance!

If you cant help please keep your comments to yourself. Or if you know how to make it stable then tell it clearly..

Problem is, you need a QX owner to help.

To a QX owner, what your doing doesnt make any sense. You were better off just buying a Q9300 and saving the 800 dollar difference.

The QX is a cpu MENT to be run on a higher multi, and lower FSB. People get QX's because they want that 10x multi.

as for making it stable, theres a lot of things involved. Voltage, and ram timings, however its very hard to tell you everything to do.

Have you tried reading overclocking guides. What your doing is the most common mistake newbies make while overclocking.

They ramp the fsb too high and expect the ram or nb to handle it like apple pie.

In short, more things can go wrong then right if your fsb is ramped up too high.
