Overclock Bios options

Hi guys

I had my CPU overclocked to 4.0 GHz and had been stable for weeks , until I updated the GPU/Video card

I had overclocked by basically increasing the Baseclock to 200, then incrementally increasing the CPU clock ratio until x 20 / 200x20 = 4.0GHz .

But recently I updated my Video card from my stop-gap HD7770 to HD7950 , since then the I had constant freezing/lockup issues ( Computer screen stayed on but literally froozen and CPU fan would stop ) . I Memtested , HDD Tested and Ran Virus Checks , though I resorted to loading stock settings which seemed to iron out the freezing.

Since I had reverted back to 'Optimized defaults' and computer is reliable enough . So now I am to start from scratch . I've read the guides and overclocked before . though I still have questions regarding overclocking and Bios. I understand base clock ,multiplier , ram and voltages , however there are options within Bios that I still feel concerned about when overclocking . I've googled these allready , though information doesn't allways take OC'ing into consideration . So please enlighten me , do these BIOS options affect stable overclocking , if so how (negative and/or positively) and simply which options should be chosen or avoided ? :
I have highlighted options I have chosen in bold
1 No-Execute Memory Protect- Enable/disable
2 HDD smart Capability ( I have HDD sentinel software already installed ) -Enable / Disable
3 Intel Turbo Boost Tech - Auto /Enable / Disable
4 CPU advanced Halt C1E -Auto /Enable / Disable
5 C3/C6 support ( Hibernation/sleep mode AFAIK)- Auto/enable/disable
6 CPU thermal monitor -Auto /Enable / Disable
7 CPU Eist Function- Auto /Enable / Disable
8 Bi-Directional Prochot- Auto /Enable / Disable
9 QPI Clock ratio- Auto /x32/x64
10. PCI Express Frequency ( auto/ 90-150)
10i CPU Clock Drive .9V ( Determined by GPU Bios AFAIK )
10ii PCI Express Clock .7V-1V ?

10iii CPU Clock Scew 0-750ps / Auto
10iv PCH Clock Scew 0-750ps /Auto

11 Load line Calibration- Auto/ Enable/disable
CPU VCore ( I understand this is OC'ed to stabilize where necessary )
12 QPI/Vtt Volts Auto /Manual ( Auto = 1.1V)
13 PCH Core Auto/ Manual ( auto = 1.050 V )
14 CPU-PLL Auto/Manual ( auto = 1.8 V )
15 Dram Voltage , termination , Channel Data & Address V Ref's all= AUTO = 0.750 V
15 Dram Voltge Auto =1.5V

How old and what Model is your Corsair. If nothing changed in your settings, it's possible the PSU is going bad.

I have a feeling you are right , will test with a spare PSU and post back


ATM though even now windows gets stuck on windows loading screen , on stock settings . Though this is usually resolved by selecting IDE Option instead of ACHI. Confused.com

I'm not sure if that issue is related to the non OC cpu/gpu. When I put a new mobo in my pc with the IDE/ACHI, option I had to do a clean install in order to use the ACHI.

I had applied the IDE/ACHI fix which works intermittently . When it does its noticeably faster than the IDE option

I would fix the issue with the IDE/ACHI first and then see if there is still something up with overclocking and the gpu. You may have to do a clean install with ACHI enabled.

Bump

Ok I've loaded a bios profile (Suppliers) which seems to work , I have had more than 10 consistent boots and ACHI is working well , however I am still very curious about the bios options (posted earlier and below)

Any suggestions , see thread

90, I think you may be in better hands with someone who is more literate with Intel products. I have only OC'ed my i5-2500 k which was a rather simple bump the CPU V core 1 notch and set the turbo to 46. Done! Hopefully someone will chime in and be better suited to help you.
