4Ghz To 4.2GHz?

post #1 of 38
Thread Starter 
First of all is it worth it? Am scared of really falling behind in the latest games now that the sandy bridge is out. Will i fall behind or will the i7 still hold up? Do games even take full advantage of the Q6600 overclocked yet?

Here are my bios settings anyway for the current overclock.
HT ON.
CPU Multi x19
QPI Clock Ratio x36
QPI Link Speed 7.56GHz
Uncore Clock Ratio x12
Uncore Frequency 2520Mhz
BCLK 210
System Memory Multi 6.0
Memory Frequency 1260MHz
PCI-E 100MHz
CPU Clock Drive 700Mv
PCI Express Clock Drive 700Mv

CPU Vcore 1.26 (1.23 Windows)
Everything else set to Auto for voltages.

Thank you very much for helping me everyone i do appriciate it.

My old rig is a Q6600@4.0 with 8GB of DDR2@800MHz. Were running 2 5770's. When I switched to the i7 (current rig) I did notice increase in performance. It wasn't a "WOW" impression. But the scores in 3dmark increased A LOT. In actual gameplay I never noticed much difference, except when running fraps. I'd say the old q6600 still is worth its money.

Yea man your good to go , i have put my i7 from 4.2 to 4.4 and i saw no noticable difference ? Imo your fine man , are you able to hold the 4.2 overclock ? are your temps alright ? if so , do it .

U wont notice much difference , though you may be bottlenecking your 2 6970's .. only a little though , overclock as high as you can and leave it or opt for a new cpu .

but from what i can see , your rig is more than capable of playing todays games .. and the ones that are coming out =) 2x6970's ? cumon .. q6600 is rubbish to what you have , and it would be a major bottleneck to most new gfx cards imo .

If your temps are good , up the vcore abit and try for 4.2ghz .. i run mine on 1.392v for 4.2ghz and i load at 68c on my h50 .

Thank you for that. I too did not see much improvement in gameplay but then again i did not take much notice anyway so i may have done.

Ok, in my bios, if i set the bclk to around 220 my memory is able to run at 1333 and i get 4.2GHz however it's unstable at my current settings. What tweaks should i make to hit this stable?
I hate my ram being underclocked just to hit 4GHz.

Edit: I've done testing to see if my 4ghz i7 is bottlenecking the 6970's. Result, not even close to being bottlenecked

Try this please ... i doubt u will be stable at 4.2 without 22x multi..

U need to drop ur bclk thats why ur unstable , higher multi and vcore and lower bclk .

HT ON.
CPU Multi x22 + turbo enabled = 24x multi x 175bclk = 4.2ghz
QPI Clock Ratio : Auto
QPI Link Speed 7.56GHz = way too high put it on auto or the lowest setting so it stays under 7ghz , it wont be stable .. mine isnt .
BCLK 175
System Memory Multi 10-12x ( depends on ur ram )
PCI-E 100MHz
CPU Clock Drive 800Mv
PCI Express Clock Drive 700Mv

CPU Vcore 1.34 - 1.36 depending on ur chip , upto u to find the stable vcore . But leave everything else on auto . I need 1.392v to hold 4.2ghz on my chip .

enable turbo while using 22x multi to achieve 24x multi = ur 4.2ghz

P.s if you want a little more bandwidth through ur pcie lanes up ur pcie freq to 120-130mhz i got quite abit more bandwidth and no damage so far .

Going above x21 on the i7 920 is not a good idea. These settings won't work for me.

Are you sure i just don't need more vcore and a higher motherboard voltage to carry the high BCLK. Btw my current QPI is stable. Don't base your suggestions on your setup as they are totally different lol.

Wait a minute, your scared your quad core 8 thread 4ghz cpu is falling behind???

Most games dont even make use of 4 cores yet...yeah I think your fine for now.

Thanks for the advice. Now how can i reach 4.2GHz so my RAM can run at 1333mhz as well?

Who says its not a good idea ? im not sure with 920's but my 870 does 24x multi fine .. but different chip i guess .

From my experience you need to lower your bclk and higher ur multi to remain stable .. and ofcoarse ur vcore .

hmm depends on your motherboard bios options.

But definitely go for the 21 multiplier, 200 bclk, and set ram to 1333 or lower. Im not sure what you mean by how can I reach this speed, do you mean you think your cpu wont let you, or your not sure how to put those settings in?
