Ongoing overclock - need help *Will be edited*

More likely CPU,

RAM is PC6400 C4 meaning its stockspeed is 400mhz with 4-4-4-12, mine does 440mhz with 4-4-4-12 and your is just running at 379.

However, I would run a memtest for like 400% coverage just to make sure it's fine.

Leave the CPU clock as it is and run 2 memtests, you can keep doing ** work while that one is working, leave it unless you get about 300-400% coverage on both just to be 100% sure :).


If that will be fine then just add another 2 notches on CPU volts and check again, your temp is still ok 53-59.

http://c.imagehost.org/0509/3_6_fft_stable_blend_not.jpg here is the screenshot continuing from the 2hour test at 3hrs - guess its the ram then

Can you give me more information on testing the ram, i burnt the iso and booted up into memtest then it ran memtest and it took about an hour and passed

i tried 3.7 and then 3.65 @ 1.39vcore and an extra increment on the ram and it failed on my small fft and blend orthos test

I belive im hitting my max overclock, unless overvolting the other 3 options in my bios are a good idea to increase overclock

Still.. going from 1.34 @ 3.4ghz and 1.368 is a step to achieve an extra 200mhz
tried 1.41 vcore with 3.7ghz and upped every other voltage by 1increment and it failed fft test

Guess iv hit the max for my chip :D
So how do i go about getting the max out of my memory and quickest way to squeeze the extra 5mhz out of my cpu

edit - tried 399 x 9 = 3599or so and my system is unstable how? this is doing a blend test and small fft
Why is my cpu unstable at 9multi and not 9.5?

System doesnt want to be stable on 3.6
My small fft test was fine but my blend test wasnt, this was with my ram running at 2.17 volts and it was only on 800mhz which is reccomended, it runs my system fine stable at 800mhz at lower voltage 1.8 when my pc isnt overclcoked
 
Could it be worth chucking in some other memory just to see if it's the memory holding you back.

It shouldn't be but you never know you may have a dodgy stick.
 
i have run memtest though, booted using the cd rom and ran a memtest fine...
I also couldnt get my system to run stable until i put 1.9v through my ram @ stock settings

What is mch ich and vttfsb?
 
MCH = Memory Controller Hub - That's your Northbridge

ICH = I/O Controller Hub - That's your Southbridge

VTT = Voltage termination - Extrememly difficult to explain.

I can tell you that it can have an fairly large impact on stability as you reach your OC limit, but it is a trial and error setting, it can be better a little higher or a lot higher, never go above 1.55v though.
 
Don't make any bootable cd's , just download the windows version and run 2 of them at same time with max memory it can handle - at the bottom of the frame you will have x% covered , leave it for at least 300%, you can use your PC while doing this so just run it and do what u doing.

If you don't get any errors at 300% coverage it will mean that's the max for the CPU, or at least at this voltage. If your temps don't go too high ( 65-68c is max i would say) you can try some more voltage, 1.41 is still not the end of the world ;).

You can also try making it the other faster way,
Set your CPU to 395x9.5, then set the voltage to lets say 1.48-1.50, see if it's stable and check the temps - if it works then just lower the voltage down by a notch and keep lowering it unless you find the lowest voltage for this speed to be stable.

Remember to keep an eye on the temps all the time, don't go over ~65-68c at max load in orthos.
 
Ok, thnx for the information
I decided to go screw it and upped most my voltages
1.41vcore (a lot of increments)
2.206 ram (a lot of increments)
1.124 on mch (3increments)
1.22 on ich (3increments)
1.60 on vtt (2 increments) u said dont go above 1.55 is this dangerous

What can i take higher or lower if its dangerous
Currently blending at 1:30mins @ 3600 stable real temp max is 56/53

If i did cripple my chip my too much voltage can i somehow decribe in the warranty a way im covered ie, i never overclocked at all? ;)
 
Not 100% sure about the VTT FSB Limit, I am just going by what others have said, however some motherboards have a CPU VTT setting so that may only apply to that and not the FSB setting you have.

As long as the temps are ok you should be fine, I'd get a temperature monitor that can read the NB and MB temperatures too.
 
Sorry I'm not OCing this rig yet, I'm getting a Q9450 in a few days so no point, as such I haven't changed from stock volts and I'm not up to date with the latest and greatest motherboard monitoring software.
 
btw i think my ram is really bad but working, at 2.2v in my ram @ 3.4ghz i could small fft test fine yet when i changed it to a blend test it fails - this is 4-4-4-12 800mhz it was running at

However at stock it takes 1.87+ volts to make my system boot into windows and then i tested my ram using the memtest cd and it worked fine?
 
You say you were running 2.2v through your ram at 4-4-4-12 800MHz then you say it took 1.87 volts to boot into Windows at stock...

4-4-4-12 800MHz is stock and your working voltage should be 1.9V - 2.4V.

Personally I think the memtest bootable CD is the best method of testing your memory as you dont have anywhere near as much OS nonsense loaded.

You should be able to boot at 4-4-4-12, 800MHz at 1.9v and it should pass memtest.

To make sure the test is fair you should drop everything back to stock including the CPU and all the voltages.
 
ok,thats what i originally tested my ram on
STOCK 4-4-4-12 around 1.9voltage i think it takes 1.87 before it lets me boot into windows

However when im clocking to say 3.4ghz and my ram isnt ever over 800mhz i can small fft test fine yet when i was doing blend tests, it was asking me to raise ram voltage - hence how my voltage of ram has now come to around 2.2

Just did a 14hour orthos test at 2400 to make sure my system was stable completely so its a good start i guess

Can you recc me the next step to go in overclocking?

Well if your running the ram at 800MHz at 4-4-4-12 then you should be able to set it to 2.0v or 2.1v as Pheonix said and just leave that as ocing the CPU shouldn't affect the voltage required by the ram.

Assuming that you mean 3400? not 2400.

Small thing; why is Orthos reporting the CPU speed incorrectly? It thinks it's at 3809? :confused:

Have you run memtest at 3400? Be interesting to see whether that reports any problems, as thats a better way of indicating a RAM issue than a blend test as a blend test is testing both CPU and RAM and therefore the Northbridge inbetween so it may that that's your problem.

What are the exact voltages you have set for everything?
 
i havent ran mamtest at 3400 i will tomorrow sometime, voltages are
1.34 vcore
2.124 vram
1.124 mch
1.22 vtt fsb
1.60 ich
400 9 3600 1:1 so dno y my cpu is seen as 3.8 in windows computer and orthos
 
just completed 2 memtests
Booted using memtest86 1.4 version

Test status
1:14min 2047 544 e820-std on off std 2passes 800mhz 4-4-4-12 2.004 voltage
Cpu 400x8.5 = 3600

Even though i did a 14hr stable orthos test is that a sign my cpu is unstable as its showing 3800 in orthos and windows properties?

Another question is when i changed settings from stock and saved and exited bios i set my ram lower than usual, (2.004) usually have (2.100)
My system rebooted and then lost connection and rebooted, i went into bios to check settings and it had reverted my vcore from 1.344 to 1.280 could that be because i dont have enough voltage going through my SB or NB? or what because im completely confused and it sounds like it wasnt stable
 
I'm wondering what's going on with some things reporting the CPU speed incorrectly and whether there could be some other hardware fault, of which this is a symptom.

400x8.5 = 3400 by the wa not 3600.

If it just reverted the vcore I have no idea why, some boards will reset there BIOS automatically if they detect instability to help save overclockers time fiddling with jumpers.

I'm afraid I'm at a bit of a loss, none of this seems to make any sense :confused:

I wonder if anyone else has any thoughts or whether it could be that maybe your motherboard or RAM is faulty or whether your CPU is at it's max.

I'm sorry I cant be any more help lighters.
