I have a couple of problems though.
1 - CPU fan error which i seemed to have fixed by reducing the warning speed to 400rpm. Tried 500rpm but it didnt fix it.
2 - CPU fan speed is all over the shop in BIOS and PC Probe. Jumping randomly from 17500rpm right up to 56000rpm!!!!!! and then pc probe warning that speed is 0 every now and then. Obviously wrong but is there a fix for this?
3 - When building this new system I found my PSU only has a 4 pin conector for the cpu and this board needs an 8 pin. It all works fine and I will upgrade the PSU eventually but should I leave overclocking until I have upgraded?
Thanks in advance guys.
P.S loving all the info on here!!

1- You can turn off the cpu fan monitoring. Any little glitch can cause the bios to shut down your system as a fail safe.
2- This is the system throttling up and down from load and of course it will take the fan along with it to cool the CPU.
3- I would get the new PSU asap as this can cause you problems with your system. I believe those connectors are for your phase control power and that will have an effect on a stable overclock.

Don't worry too much about your CPU fan as long as it is from a quality manufacturer and is connected correctly. You shouldn't have to worry about it for a long time if you can keep the dust off of it. I let a few fans go and it slowed them down considerably, so bad that one seized.

Thanks for the reply. as for number 2, I can here that the system is at idle and the fan is a steady speed, also that the CPU is a steady 4% but the fan speed still indicates 17500 - 56000rpm. There is no way this fan could even spin at 56000rpm. Its definately a glitch or bug in the bios or something and would be really nice to fix.
I have read of others with the same problem but so far havent found a solution. Anyone have any ideas?

Oh, also another problem, after the ASUS boot screen, all goes black with a blinking curser at the top left for about 40 seconds before it goes to the windows screen. Any ideas?
It is a clean install of windows 7 on a Samsung F1 by the way.

Thanks guys smile.gif

More than likely your bios is searching for hardware that is enabled but does not exist. Onboard sound, bluetooth etc. Check your bios and disable any of that which you don't need and it should bypass the auto check for it.

I havent installed the jmicron drivers from the CD so i just disabled it in bios. That seemed to fix the boot delay.
Here is a really noob question though frown.gif I just disabled the splash screen to speed up boot time but del doesnt enter the
bios anymore. Just some other options, lol.
How do i enter the bios without the splash screen please? pretty please? redface.gif
post #7125 of 9345
Srry guys, been trying to sort this for hours. Trawled the net but no joy.

Question is:
After disabling the splash screen, which key gets me into BIOS?

tried all f keys, and its not del anymore either frown.gif
post #7126 of 9345
As soon as you hear the beep I start pressing the del key, a lot of times it happens long before the splash screen or I miss it and it shoots into windows,
post #7127 of 9345
Ah ha! that could be where the problem lies as my case has no speaker (no beeps). Will give it a go
post #7128 of 9345
OK, all going well smile.gif

Turned off jmicron and splash hugely improved boot times.
Setting Qfan profile to Turbo sorted all the fan problems (erratic readings, 0rpm warnings, cpu fan error f1 warning)

Only thing left for now is turn off marvel but I cant find it in the BIOS?

Thanks for all the help so far Mercy!!

Are these Bios Settings Safe?

Hello everyone my name is Peter and I have just finished building my first custom computer tower with great consideration and research. I did 2 months of everyday research before I finally ordered the parts. I had a friend put the the tower together. I am attempting to overclock this tower mildly to a stable 4.5ghz but have not been successful in running a 12hour custom prime95 blend at 1344 fft or 1792 fft with 90% of my ram being used, I can pass maybe about 3 hours of prime95 but not 12 hours.

I have the following computer setup

i7-2600k 3.4ghz - 3.8ghz turbo boost
Asus p8p67 evo motherboard
2 kits of 2x4 gig dimm modules, each kit volt recommended at 1.5v, 16 gigs of ddr3 1600 ram total , timings at 9-9-9-24-2t
nvidia gt 430 gpu
700watt coolermaster silent series psu
nzxt h2 case
noctua nh-d14 heatsink

I am seeking advice/knowledge on

A) if my bios settings are safe and within acceptable value (based on personal preference of course)
B) if you have any recommendations to some changes I should make to my bios, what changes should I make?

These are my BIOS settings..

Ai Overclock Tuner = Manual
BCLK/PCIE Frequency = 100.0
Turbo Ratio = By per core
All cores ratio limit = 45
internel pll overvoltage = Disabled
Memory frequency DDR3 = 1600mhz
EPU power saving mode = Disabled
enhanced intel speedstep technology = disabled (Saving power does not benefit me and my purposes for this computer, I need constant power
and a constant 4.5ghz overclock)
Load line Calibration = High
VRM Frequency = Manual
VRM Fixed Frequency mode = 350
Phase Control = Optimized
Duty Control = Extreme
CPU Current Capability = 130%
CPU Voltage = Offset Mode = CPU offset Voltage -0.020 <-- I see a lot of people use +0.05 offset etc, maybe I should too?
Dram Voltage = 1.55 <---is this enough for 16gigs of ram? its rated at 1.5v but thats for only 2 x 4 gig dimms, i put 2 sets in my dimm slots so im not sure how much i should put for voltage. When set at Auto it was 1.65v
VCCSA Voltage = 0.925
VCCIO Voltage = 1.15
CPU PLL Voltage = 1.54375
PCH Voltage = 1.02 <---- was on auto but I read somewhere It could be lowered without affecting stability. was at 1.045 so I lowered it a little.
CPU Spread Spectrum = Enabled
CPU Ratio = Auto
Intel Adaptive Thermal Monitor= Enabled
Hyper-Threading = Enabled
Active Processor cores = All
Limit CPUID Maximum = Disabled
Execute Disable Bit = Enabled
Intel Virtualization Technology = Disabled
Enhanced Speedstep technology = Disabled
Turbo Mode = Enabled
CPU C1E = Disabled
CPU C3 Report = Disabled
CPU C6 Report = Disabled

Now I have read lots and lots of threads/posts on safe/acceptable bios settings/values and have done lots of tweaking myself without asking for help, however I have not been successful in running a 12hour prime95 test without hours or BSOD's, so I graciously come to this forum and seek advice/help from more experienced overclockers.

How does my BIOS settings look to you? Would you change anything? if so, what would you change and what would you change the value to?

Hello, Peter, welcome to the forums!

There are a couple of things in your post that caught my attention:


Phase Control = Optimized
You mentioned that it's not important for you to save power. Try changing this to Extreme, that could possibly help with the system stability.

CPU Voltage = Offset Mode
Check how much VCORE is CPU-Z showing for your CPU inside of Windows.
If you do the Prime95 test and one of the cores is falling far behind or failing, you might want to up the voltage.
If you are not saving power, you could change the VCORE adjusting to manual, so you could use your preferred voltage.
Make sure to adjust the VCORE accordingly after checking how much the motherboard is recommending for the current overclock (just make the needed adjustments later).

Dram Voltage = 1.55 <---is this enough for 16gigs of ram? its rated at 1.5v
If all 4 of the sticks are rated at 1.5, better run them at 1.5VDIMM. It's also better for Sandy Bridge (2600K) if you don't exceed 1.5VDIMM for 24/7 use.
It might not matter in the beginning if you exceed 1.5, but it probably will in the end. The memory controller is inside the CPU and according to common beliefs, over 1.5 stresses the CPU.
If you aren't planning to overclock your memory, increasing VDIMM is not necessary.
