overclocking amd 6400+ black

[fullinfusion]

After two weeks testing my rig at a lower voltage since the summer is next to come (i downgraded from 1.52) ... i found stability at 1.47V during one week doing all but failed with the F@H SMP client (100% cpu) & Counter Strike Source at the same time, i upgraded a notch till 1.49 and it's 100% stable again.

Stability tests done (295x12 - HTT Link 4x - Ram divisor of 6 ~ 3540Mhz - 1180Mhz - 1180Mhz)

- 8 Hours AMD Overdrive Stability Test (with Calculation Test enabled)
- All night 3DMark 06 in loop test
- Gaming for several hours (with video cards overclocked)
- wPrime 1024M 1.62 + wPrime 1024M 1.55
- F@H SMP Client for several hours
- F@H SMP Client + Counter Strike Source (with video cards overclocked)
- 24/7 use succesfully for more than a week w/o troubles, freezes or BSOD's

Voltages used:

- CPU Voltage: 1.488V
- RAM Voltage: 2.30V
- RAM Timings: 5-5-5-15-20-2T
- HyperThreading Voltage (NB-SB): 1.40V
- Core/PCI-e Voltage (Northbridge): 1.18V (but was stable at 1.16V)
- NB PCIE PLL Voltage: 2.1V

I'm adding a screenshot of a hot day (26-27ºC of ambient temperature) when i was testing the F@H + CSS, i folded for 3 hours and then started the monitor to check the max temperature for the fold+gaming, global CPU socket never went over 44ºC:

Idle temps on cores use to be 31-35ºC/25-30ºC depending on the ambient temperature that can vary from 22 to 26ºC

Hope this help to anothers, good luck with the OC

very nice SIR.... Very NICE!!!! nice setup...

nice man ,... very nice

Thanks to both of you, really

I wish i could run it 24/7 at 3,6Ghz - 1200Mhz - 1200Mhz ... but every thing i try seems to be unuseful and it's pretty sick ... totally stable at 3,54-1180-1180 with tiny voltages and the 3,6 setup seems impossible with any voltage i try, it's just a bump of 60-20-20 Mhz and i can't stabilize it, BSOD after BSOD when running F@H or any "number cruncher" ... if any OC guru wants to help me, i'm opened to suggestions though i'm happy of the OC i reached too



ps: I forgot to mention my "Auto Xpress" BIOS option was "on" for these last two weeks which means a PCI-E Express Frequency at 125Mhz ... but it's not like changing it manually, my Hard Disks didn't had any fail and neither CD's or DVD's ... this option it's specially designed by AMD and i suppose it just ups the frequency for the video cards suring the system stability, i also read that it's useful for a CPU & Memory performance boost ... at least, worked flawless for me

nice going sir!
thats pretty badass! are you running watercooling?


are you guys getting huge performance increases with these high fsb overclocks with low multiplier..
i've sorta come to the conclusion that these AMD chips like multi ALOT more than FSB increase

if i leave my Mutliplier at 16x and push the fsb to say 15, i get a significant jump in games performance and benchmarks over stock and over a high multiplier and low multiplier..

i found that sure, you can get a high clock when the FSB is pushed and the multi is lowered, but the performance just doesnt really go anywhere?!
or am i just being a retard and doing something wrong?

struggling to keep it stable at 215x16, 4.4.4.15
=/

My ram is Supertalent DDR2 800 CL4..

 

[SirKeldon]

Yes eyetac, i'm watercooled, my 6400+ liked to run hot hot ... and i thought doing this inversion for this overclocking and future ones too about 2 months ago ... and sincerely i'm so so so happy, load temps are a miracle =)

For the other question, talking just about my chip ... he always loved high FSB's as well as high HTT links, the performance was a lot better in every thing i did at the same speed with high multi's ... besides that, with lower multis you can overclock more the RAM since the dividers will be smaller ... and if memory is stable that will give you clearly more performance, for sure.

The only odd thing to run a higher FSB with low multi is the voltage needed for the CPU, most of times will require one or two notches more that the same speed with a higher multiplier. Also take care at the voltage of the RAM ... if you overclock it, you'll need to add some volts too.

About the clock speeds, i think you'll get the same "top" speed with high multi's than with low ones ... the performance is better since all the rest is extra-overclocked as well ... and also the depth of the main bus is bigger, but that's all.

Try upping your ram volts by .1V when OCed.

I realize this thread is very old, but I just want to mention how much all of you helped me. I never could have overclocked my 6400+ black edition to 3.45 GHz without any of you. I'm stably running at 1.47V. I created this account just so I could thank everyone here, I really really appreciate it.

You're very welcome. And welcome to tpu. Hope you stick around and learn more.

Noes! I get BSOD's on 3DMark06 (although Prime95 checks out good). I have a feeling this might have to do something with the amount of voltage I'm putting into my RAM, except I don't know how many volts my current RAM is. CPU-Z doesn't show me. Any ideas?

Thanks.

 

[Whef]

Whoops, sorry about that. I found it. It's under the SPD tab.

i dont trust Prime for stressing... i've heard it can fry the mobo..... if you have Amd over drive use that for stressing... just un click the calculation tab before you start the test... it's more for testing a quad... and just give your ram a +1 click to the volts and see how it works for ya... good luck

Okay, thanks for the advice. I do have AMD OverDrive.

Also, I bumped up my RAMs voltage to 1.9 from 1.8 and now it's working better, but it still BSODs while running FarCry 2 or Crysis. I think it's just because my RAM is really HORRIBLE. Oh well, I'm buying some new 4GBs in a few days. Thanks.

 

[Mrkwhlr2]

I Have My multiplyer at x15
Bus speed at 225

For the life of me I cannot get my bios to save the voltage to 1.4 or anything that I try and set it to.

After I set the voltage and hit F10 to save settings in bios, I fire up CPU-z and my core voltage is at 1.280 no matter what I do.

I am trying to set a 230 bus speed and I am thinking the voltage is holding me back.

any suggestions?

when you go back into the bios what does the voltage say?

cool... keep us updated mate.
one other thing did you loosen up the memory timings a bit also? that also helps out poor ram

When you save the changes and your computer shuts down does it start back up succesfully on it's own? My computer takes like 5 seconds to start back up and I was trying to press the power button again cuasing it to have a failed boot and it resets it to defaults on some settings or some whatnot like that.

Also, I'll keep you updated on the RAM and try loosing up the memory timings while I'm at it. Thanks!

 

[Mrkwhlr2]

when you go back into the bios what does the voltage say?

1.400 volts

 

[fullinfusion]

1.400 volts

weird.... try going into hardware monitor in the bios and see if there is an option to change the limit of the cpu voltage... Just a shot in the dark man...

 

[Mrkwhlr2]

In the bios/JumperFree Configuration

AI Tuning - Manual
CPU Freq - 225
PCIE Clock - Auto
DDR2 Voltage Control - Auto
CPU Voltage - 1.4000v (but still indicates 1.280 in cpu-z)
CPU Mult - 15x

CPU Voltage gives me the option to apply the following: 0.8000v all the way up to 1.5625v. I am assuming this is the correct area to apply the voltage. I was trying for 1.4v to start with due to previous post suggestions.

In the advanced Voltage Control CPU/Chipset HT Voltage is automatically set to 1.20v
Chipset Core Voltage is set to 1.4v
Chipset Standby Core Voltage 1.4v
Chipset PCI-E Voltage 1.5v
CPU Vcore Offset Voltage Disabled.

should any of the above be the culprit?

I think I am going to get a 9850??

Hardware monitor:
Vcore voltage 1.43v the only option is to 'ignored"
3.3v Voltage 3.38v
5v Voltage 5.10v
12v Voltage 12.43v

 

[Mrkwhlr2]

What is the Vcore voltage anyway...

 

[fullinfusion]

What is the Vcore voltage anyway...

thats the cpu core voltage...
hang on ill link this thread to a buddie... he might have an idea

CPU Vcore offset voltage... ENABLE IT and see if you can go higher
and also go to Cpuid and d/l the latest cpuid

@ Mrkwhlr2

Hi there buddy see your fairly new here so first off welcome to TPU.

Now down to business. Do you have eveyrthing like power saving features and cool & quiet disabled? If you can possibly get us some pictures of your setting in the BIOS that will help tremendously!

 

[fullinfusion]

does your mobo support 140w?
if so id forget the 9850 and get the Phenom II 940
