Q6600 G0 + P5K Premium -> 500FSB??

[ripken204]

i finally have time to work on OCing my computer.
my cpu can do 3600MHz with a mult of 8x or 9x
now i want to make it do 7x with 500FSB -> 3500Mhz

the problem is that when i set it to this, my comp doesnt even want to POST at times. and if it does the overclock fails..

is this my cpu? i have seen other ppl getting the mobo over 500FSB so i dont see that being the problem.. is there a voltage i should increase somewhere?

[Envydia007]

I think its your memory.

[ripken204]

also i can boot at 490FSB but it wont load windows correctly
480FSB works perfectly

ive been running my ram for months at 1000MHz at the same timings and voltage.. would FSB make and difference to the ram if the ram is still running at 1000Mhz?

Believe or not if your ram has promos chips on it then you might want to try dropping ram voltage to 2.0. I seem to get my best ocs at that voltage. Also there is BIG fsb gaps on these asus boards. Meaning it just doesnt like to be at a certain fsb. Try 495 then make adjustments from there.

500FSB with a quad is rare...

[ripken204]

so it is my cpu then?
i know its not the ram, i put it on a divider to make it run at a lower speed.

[Leeghoofd]

CPU FSB wall mate, and lack of bios controls, this is where the DFI pops in , as it has numerous tweaks more to get (maybe) it going , though like mentioned before your CPU walls prolly, these are not dual cores peeps seem to forget that... and what's the advantage of running 3500 with 7 x 500 ? do you really think it's faster than 9x 400 ? sisoft sandra might give ya impressive bandwiths but in games and co it really is of almost no benefit and surely not for 24/7 use...

[revogamer]

and most quads dont get 500 fsb.

[Biker]

My P5K Premium (rev 2.00g China) can do 500 x 7 with my L731B158 Q6600 stably, however it has had other issues, mainly with the ICH9R. see here...

My Quad... on my Blitz Formula



.... liquid cooled!

[Leeghoofd]

Can anyone clearly indicate me why it would be better to run 7 x 500 then 9 x 400 ? I don't see the point at all

[ripken204]

i only want to do it so that i dont have to run my memory on a divider

[turtletrax]

Can anyone clearly indicate me why it would be better to run 7 x 500 then 4 x 900 ? I don't see the point at all

Show me a proc that can do 900 FSB and I will show you a thousand heavy OCers begging you to sell it to them

[Leeghoofd]

I got one lol typo error hehehhe ( corrected the post )

[flesheatinvirus]

My Asus P5K Prem has done 513FSB so far with my L726A849 SLACR quad.

[Leeghoofd]

primestable or suicide shot ? cooling used ? mobo mods ?

[flesheatinvirus]

I did not check for prime stability but it was not a suicide shot. I did some 3dm06 runs to compare that combination of 8x500 with 9x445 and 8x513 vs 9x556 to see if it was any better which its not and requires much more voltage to remain stable. Rev2 china Asus board with bios change to 0404 using Teamgroup ram. Quad on its own water loop using PA 120.3 rad with no other mods to board.

How do you make memory run slower than the FSB on this board? Last I knew there were no dividers (only multipliers) on an intel board.

Many OCers prefer to run their memory at 1:1 so if you have memory capable of DDR2-1000+ you will be able to run 1:1 at 500FSB. Otherwise you need to use the dividers/multipliers to push the memory to its maximum capability which cna lead to more problematic overclocking (less stable sometimes).

The benefit to running at 9x400 obviously is less stress on the board as you will need higher NB voltages to maintain 500FSB, expecially with a quad.

Yeah I got that but doesn't anybody think about how you shorten the boards, CPU's lifespan with such high clocks and voltages...and my point is what's the total benefit in day to day use ? I like to play on PC's, OC them mess about, but to me there's not much difference in my online gaming with a quad at 3.5 or one running at 3.6ghz...

It might be cool for benching but some really want to use these settings day in day out... and then they come back with a topic like "board A sucks ass", "RMA takes too long", "got B board","B died on me in half a year", "RMA sucks again..."

Some here are really thinking they buy high grade stuff, build it and hopla I can run 500FSB now till I get something new...

Hope you get my point...

True though I personally have not seen any great increase in bench scores running a high FSB combination other then mem bandwidth on Sandra and it requires more voltage to remain stable.

I am sure people think about shortening the life of the board, but this is XTREME SYSTEMS where people pump 1.9v into an $1100 CPU (QX9650) and burn it up for the sake of benching. The only people that will complan about it are people that want their cake and eat it too. 500FSB with a dual core should be a breeze (assuming the CPU is capable) and by that I mean with little vcore increase. I had a DFI-P965S and an Abit IP35Pro that would reach 500FSB with no voltage increase at all (except to the CPU of coarse, and that was 1.52vcore on an L629B E6600 running at 8x500). 500FSB with a quad will surely beat the hell out of the board. I run 464FSB x8 with a quad and I do not have to bump the NB voltage at all. If I go to 475 I need to bump it some and today I was messing around with 500FSB and fried one of my sticks of Crucial 10th Anni RAM. I am not sure what exactly caused this to happen but I believe upping voltages was somehow tied to it. Can't complain though as I intend on stressing my components because it is FUN and almost an addiction.

Very true but any increase in performance is key to benching and if one needs to sacrifice the equipment to get it they certainly will. At least those of us that want to see just how far we can push our hardware.

[flesheatinvirus]

I always push my systems beyond hell and back to test for potential issues for that particular combination of hardware but for benchin I shoot for the highest clock period and that usually means high multi with lower FSB. Here is a run of Pi 32meg at 515FSB on my Prem I just ran a few minutes ago. I used my Ballistix 6400 with 333 strap at 2.35v 1-1 FSB
