Overclock & PCI-E Frequency possible issue?

[JHLOW]

Hi All, I currently have my setup in my sig overclocked to a very stable 2.88Ghz, but i thought id have another go at getting a better overclock which im in the process of at the moment, I have set my motherboard jumpers to strap the N/B at a higher voltage, which in turn puts my fsb:dram ratio to 1:1 which is what i need it at to get the results im looking for.

While adjusting my fsb anywhere upto 333Mhz my PCI-e frequency stayes at 100Mhz which is great, but i want to up the Fsb for a higher overclock the problem is if i increase the fsb above 333Mhz the Pci-e jumps to 103Mhz fixed (grayed out in bios).

My question is is it ok for the Pci-e freq to be at 103 or not,will it cause any adverse effects on the system or overall performance...

All my adjustments are done in bios the Asrock Oc tuner is in the screenshot just for info.....

Any help would be great.....

i just noticed that your q6600 has a very high vid so u might not get a high oc with that, but i can see your cpz you have only 1.272v going to the cpu so it looks like your suffering some vdroop if youve not touched the voltages and thats maybe how u arent getting it stable at 3hz, go into the bios and set it more similar to your vid if its set at that up it a little bit more these chips can handle 1.4v

as for the pci-e frequency im not sure about that as mines is always set to 100 automatically and doesnt move

also make sure you have c1e disabled and speedstep disabled 2

HI Stepster, It's not that it isnt stable at 3Ghz i havent done any stress testing yet, All Voltage settings in the bios are on Auto atm, SO i will do as you say and set it manually to 1.3125v. everything in bios is disabled, I am not so new to O/Cing so understand it all to a certain point...Its just my mobo is s***e.

I have done a little reading online since posting this and found that some peeps have their pci-e at 110 or 120 so i will at themoment assume my pci-e at 103 is ok and contine with the overclock and test as i go and post here how i get on. The main problem i have atm is i am doing this on a g41/ichr7 chipset asrock mobo which isnt really designed for overclocking! but i want more speed until i can stretch to a decnent mobo for my q6600 G0.

yeah i didnt think it was that good a mobo and thats how ur prob not gonna get a large oc out of it, but another thing to think about in your bios see if you can find a thing called LLC its load line calibration it helps stop vdroop

second hand mate u can get good m/b for oc'n mines for example is an Asus ROG Maximus Formula only cost me £40 and its a great m/b for oc's and i havent even really hit its potential in the process of gettin myself a higher end air cooler to replace my h50-1 as im really not liking it anymore

what do you use do to stress testing? try prime 95, occt, orthos, intel burn test (thats good for speedily pickin out an unstable oc only takes like 7-8 mins)

also i usually use real temp to monitor temps cause i find its closer to the temps in the bios and its nearly identical to everest

To be honest the bios is pretty bare when it comes to overclocking tools/settings, No LLC to stop Vdroop . I have been looking at 2nd hand boards but they more often than not are sold as faulty and i cant really afford to waste money for what may be non working, when im looking at getting a new Asus P5Q deluxe, or the board you have actually, for arund £120 for the P5Q and around £145 for yours.

for stress testing i use IBT, Prime95. I havent tried any others yet. I am going to download realtemp though as i see alot of peeps use it...+ Hw monitor is all over the place with the temps it think my 12v is a 7.2v......I would like Everest but i need to pay for it and i tried the trial version but dont like that dont get full functionallity...

I have had to give up on the overclock tonight and go back to my mega stable setup i had earlier as it seems to be bomb proof even though i have had to increase NB volts and Vcore as i get constant Vdroop under load/stress testing or online gaming i lose around .75 of a volt on average...

Looks like ill have to put up with the current oc until i can get hold of a new mobo...... I can't belive i actually bought this board to be honest but then i did take advice form an Asrock junkie.......That will teach me not to do my reasearch.........How old is my chipset lol..........

Mate, I got my hands on an Asus Striker II Extreme (Factory Refurbished) from flea bay for £70. It was just the board, accessories cost about another £30, but for just over 100 smakeroonies I got a top end board !

I've never played on the op's board but there's probably a bit of slack spread-spectrum wise... hence the slightly squiffy speed reported.

I've witnessed boards that were oddly more stable at numbers like 101m and 102m as opposed to 100m... perhaps it stops the boards doing some odd multiplication...

My guinea-pig board at the moment is at 155 and I'm seeing nothing performance wise in windows. You have to actually use all the capacity to begin with to see any advantage in raising it (aside of the unexplained stability)... do the math on your bandwidth across the slots and see if it's beneficial...

...this behaviour doesn't occur on my GTXs but still...anyone got any 9x00's to test?
