Pretty sure i can go faster.

[Mastikk]

Hi yall.
I'm pretty new to overclocking in general, but i'm sure my graphics card will go faster, but I must be doing something wrong. As every time I overclock it I get worse framerates in my games, ARGGGHHHH!!!! Please help.
So far this is my pc:

ASUS P5Q pro

E8400 wolfdale @ 4.00ghz 442mhz FSB 9x multiplyer (1.47v)

8gb Corsair 6400 @ 885mhz or there abouts lol 1:1 ratio 5-4-4-14 (2.2v)

XFX Black Edition GTX260 Graphics Clock 666mhz / Memory Clock 1680mhz / Processor Clock 2808mhz

OCZ Turbo 30gb Boot disc with Windows 7 64

800W Power Supply

+ more hdds, phys x and other attachments

If you can see anywhere I can improve or anywhere i've gone wrong with what i've done thus far, please point it out.
Thanks

Dude, open up cpuz and let us know if you have an E0 or C0 processor. 1.47v for 4.0Ghz is insane.

Got it stable taking it back to 1.4v. gona try lowering it even more later. Its a CO processor. How much difference does it make? I took my ram voltage back n all but had to increase timings again. It was too buggy while gaming . Looks like I was being a peen arse when checking over graphics clocks. Ones i posted where my max speeds it will let me increase too. The stock speeds are:
Graphics Clock- 666mhz
Mem Clock- 1150mhz
Shader Clock-1404mhz
Serves me right lol. Wont be having mates over while overclocking again me thinks

 

[Mastikk]

Ok BioS settings thus far
CPU Ratio - 9x
FSB - 444mhz
PCIE Frequency - 100mhz
DRAM Timings 5-5-5-18
CPU Voltage 1.4
DRAM Voltage 2.1
CPU Spread Spectrum - Disabled
PCI Spread Spectrum - Disabled
CPU Margin Enhancement - Performance
C1E Support - Disabled
Execute Disable bit - Disabled
Everything else is pretty much set to Auto
But let me know if you need any more info
Thanks

 

[Mastikk]

yep cant go lower than 1.41 so far without pc blue screening!!!! any suggestions?

 

[Mastikk]

thanks for the warning. im starting again from scratch seing as ive learnt alot from everyone here in the past few days. will continue ocing after work tomoz and will post new results soon. any critical advice before i restard would be much appreciated. thanks peeps

Auto is not your friend when overclocking.

At the very minimum you need to set:
CPU
FSB Term
DRAM
NB Volt
SB Volt

and a very good idea to set GTL Ref voltage and PLL

 

[Mastikk]

Ok cool.
This is new set up. Think its a good starting point.

FSB Freq 400mhz

PCIE Freq 100mhz

DRAM Freq 400mhz

5-5-5-18-3-Auto-6-3-8-3-5-4-6-4-7-14-5-1-6-6 Auto on the rest. (that should all be ruffly manufacturers settings)

CPU V - 1.3v
CPU GTL Ref - Auto
CPU PLL V - 1.5v
FSB Termination - 1.2v
SB Voltage - 1.1v I think the NB is at 1.2v/1.3v (Forgot to write it down )

All Spread Spectrums - Disabled
CPU Margin Enhancement - Performance
Max CPUID Value limit - Disabled
Execute Disable Bit - Disabled
Intel V tech - Enabled
Intel Speed Step - Enabled

Does my CPU voltage still seem a litle high for such a small over clock?

 

[Mastikk]

Excellent. Ive turned on the C1E Support and speed step n all that jazz. PC still seems stable and happy to lower the ratio by its self no problem.
Decided I'd try and get some tighter timings with my ram.
On the Corsair website they say they got my RAM down to 4-4-4-12 timings at 400mhz at 2.1v.
I've had no luck. The PC boots happily enough but its really unstable, random restarts and closing programs.
So I took the timings back to 4-4-4-15. Better but not great.
Should I be increasing the nb voltage aswell?
I'm not entirely sure how to work out the GTL reference voltage too.
Any suggestions would be great. Thaanks for your help so far aswell.

 

[Mastikk]

I didnt even bother stress testing that. It rebooted while just food shopping online.

 

[Mastikk]

I think its ok. Prim95 and MemTest found no errors. With the temp only hitting 54C.
Thats with these settings
Multiplyer 9x

FSB 400mhz

PCIE 100mhz

FSB Strap top NB Auto

DRAM Freq 801mhz 5 5 5 18

DRAM Static |Read Control Disabled

DRAM Read timing Disabled

Mem. OC CHarger Enabled

AI Clock Twister Auto

AI Transaction Booster Auto

CPUV 1.31250v

CPU GTL Ref Auto

CPU PPL V 1.6

FSB Termination V 1.26

DRAM V 1.9

SB V 1.1

Spread Spectrum Disabled

NB Clock Skew Auto

CPU Clock Skew Auto

CPU Margin Enhancement Performance

C1E Support Enbled

Max CPUID Value Limit Disabled

Intel V tech Enabled

CPU TM Function Enabled

Execute Disable bit Enabled.

How do those seem?

Im going to leave Prime95 running all day while im at work make sure there are no probs after long time.
Any ideas on what I should do with the stuff ive got set to auto? Or where i can find a simple explanation of what they do?
Thanks
