Some info in there for you

Thanks crazy, now in my last post I accidentally put CPU Shew, but I meant CPU and PCI-e Amplitude, which I have the settings of: 700, 800, 900, and 1000 Milli volts. Now I was unsure what what that meant. Although, I also needed to know what the CPU Shew is also since both CPU amplitude and CPU shew are in the same menu under ClockTuner in my MSI BOIS.

Well maby does someone here knows how to raise my PCI-e freq without freezing? Tried to raise the PCI-e freq votlage even to the max (2.16v) but that didn't help!

if i can raise my pci-e freq till 110 or higher i know i can easily reach 4,8Ghz

 

[n-ster]

is it not the max Bus speed that is limiting you?

What link is there between pci-e freq and your max OC?

Sorry for the noobness lol

 

[mudkip]

wthout raising the pci-e freq my max blck is 222, when raising the pci-eq only with 2 mhz i could reach 4752mhz . Some members on xtremesystems reach over 235 bclk when they set their pci-freq to 120 ! But i don't know why i can't raise my pci-e freq any higher! Obviously increasing the pci-e frequency , also gives more headroom to raise the bClk.

thanks for the info!

It will also destroy your hard drives if they are not solid state.

Best run I have had so far. 4.165 with HT off I think I can go higher with HT off, maybe something like 4.3 or 4.4 since the temps are not much of a problem.

holy crap, that screenshot is too small. can't read anything on there.

Took the pic out since it was in 1080p and the attachment thingy made it tiny so it is pointless, but it was 4.168 at BCLK 198.5 Vcore 1.408 with a 21 multi. Memory was 790 @ 7-7-7-22. I am liking the new OCZ 1866 platinum set I got, and paid a cheap rate for them too.

If you guys join the Core i7 Overclockers club we can help establish a database so new time i7 users can get quick information on what to expect of an overclock. Since I guess this thread has millions of duplicate questions as it's nearly impossible to find what you're looking for

ok got my i7 920 Asus Rampage Gene and 3gb gskill 1333mhz both running at 3.2ghz and 1600mhz by using asus auto clock, i wanna see what this C0 can do, where do i start ?

By raising the BCLK. See how high that gets you before messing with voltages. If you're lucky, it will be 3.4-3.6 before you need to add juice. Stability test in between. Are you using the stock cooler? If so...watch your temps. Try to keep them below 80c, if possible.

 

[Jakethesnake011]

Been able to hit 4.1 now with HT on and running 1.416V on the Vcore and 1.34V on the QPI, although it is BSOD on me some time into my LinX test.

its damn hot cores hit 87c (max, although they were averaging about 75c in reality) on the intel burn in test but managed to get to 3.6ghz on stock volts by just raising the bclk, although im confused as to what stock volts are meant to be on these chips as its reporting about 1.32v in the bios and 1.272v in cpuz, i doubt thats vdroop so im assuming the bios is correct for now.

am going to try and drop the voltage a tad and see if the chip can handle it, tough shout but hey got to 3.6ghz with no trouble at all maybe it can do it on lower volts.

any other suggestions ?

Anyone overclocked on an Intel mobo yet?

 

[Fitseries3]

wow guys....

Gb x58 has awesome bios.

one problem though...

it trys booting windows then the machine turns off.

any idea why?

overclock is not stable?

Flashed the newest BIOS yet? I'm currently running with the F8B bios and my overclocks are rock solid.

no , why would we?

 

[InTeL-iNsIdE]

looks like i might have a nice C0 chip its running undervolted to 1.22v @ 3.6ghz just by raising the BCLK, gonna try a burn in at these volts. how low should i try take it, i wanna find the lowest volts possible and get to 3.8ghz from there for a 24/7 OC

Let me rephrase that: Anyone overclocked an Intel motherboard yet?

Hmm, haven't had that problem with my UD5 or UD3R. Are you at stock clocks right now?

 

[Fitseries3]

i guess it just wanted a little TIM.

[InTeL-iNsIdE]

undervolt went well using intel burn test on default settings 5 passes max cores got was 82c, going to try for around 1.2v now

btw what effect does hyper threading have if any when overclocking ?

LOL. I've done that a time or two.
