^ thanks bro. yup its stable.. but i want to lower my vcore.. i think its high.. here's another, but different procie.. E7400,, =)

[Leeghoofd]

How high is the FSB term voltage ? Sometimes upping there can reduce ya Vcore a bit, this conciding with GTL tuning. Don't expect miracles of it though... If ya really are scared of the voltage just use the CPU at 4Ghz... good rams help loads with quad clocking...

[Padol_Inc]

FSB term voltage is at 1.34v, im still waiting for my 1200 rams from US to the philippines.. hope it will arrive soon.. =) thanks leegh for the inputs... =)

[davidkozat]

dude if anything you cpu voltage is suprisly low for that clock mine is only doing 3.8 and is stable at 1.55... i suppose i can affort to as am watercooling it...

by the way did you 3d mark it?? if so whats the score?

[BababooeyHTJ]

Alright i dont think that 1.55 on the CPUv is that much.. or 1.6 PLL plus i get it stable and i dont know how to adjust NB GTL so i wont touch it dont wanna kill the NB i dont think ill go any higher here so i wont try thanks anyway and by VTT you mean FSB voltage?? is set to 1.3...

Honestly, you may want to read this thread. There is some good stuff about GTL reference voltages.

-n7- also has some really good tips for clocking a quad with four occupied dimms on this board in a post a couple of pages back.

I think that your crazy not to pop out 2 sticks and play around just to find out what the chip actually needs with the extra stress from the ram out of the equation. It's all about fine tuning and throwing more voltage at everything is not going to help. Just because your prime stable dosen't mean anything since your mch could still be unstable and cause random issues and data corruption. With my quad and four occupied dimms on unstable clocks I have passed prime (small fft and blend), linpack, and memtest (86+ and 3.8). It's not going to happen overnight.

dude the whole point of me using 64 bit is so i can use more than 4 gig... that why am using 2 gig stick on the 4 slots and am happy at the clock am on i dont wanna course more strest on the board so am happy at 3.8.... plus i been letting my mates play crisys warhead all night with out a problem and still up and running with no probs ill take 2 rams out just to if there is a differeces in stabily and let you know matey

thanks

[davidkozat]

Do you guys think that is worth getting a Q9550 ?? am tired of this Q6700 the new q*** run cooler and at a lower v cos they are 45 nm die so ill be able to overclock a bit higher and 12 mb on cache is nice?? :-)

[Leeghoofd]

Well if you can afford it skip the Q9550 and go straight to Q9650 Davidkozat, but is that worth the cash ? You prolly will be reaching 200-300mhz more at a far lower Vcore, but that's hardly reflected in games (max fps yes, average fps not really)
But limiting factor could really be ya rams, as you need very loose timings to get them anywhere stable

[davidkozat]

You are right depending on the price... to be honest i play on a 28 inch doing 1920x1200 so i would like the most out of my pc?? what i dont get is the differences on price between the Q9550 (which is £ 170.00) vs the Q9650 they are identicle except the last in 200mhz faster?? and is £ 70 more !! about 100 ~ 110 dolars?!! is not worth the price?? is it because it runs cooler and with less voltage or because it uses a higher a 9 multiplier... if so ill get the E0 rev.

[davidkozat]

Ok so i tested 3d mark the system with 2 sticks of ram out and i got a little more score



so do you guys think i shoud have 2 lots of 2 gig or 4 lots of 1 gig as i wanna keep my system stable...

You've got a Q6700...piece of cake to OC really, as you don't need to bother with high FSBs unless you want.

8 GB isn't really an issue till you start running high FSBs or really high RAM speeds.

You can do 10x400 & not even be pushing your mobo really, as you have a nice high multi at your disposal.

If you want better numbers in benches like Everest, then doing a higher FSB helps, like you've been doing 9x425.

Up until around 440 in my experience anyway, you don't even have to touch GTLs really.

So in your case, if you are happy with 9x425 4:5 & it's truely stable, i'd then work on RAM timings & then lowering voltages.

I'd make sure that's passing max RAM stress on LinX, & HCI Memtest (4 instances set to ~ 1200-1500 MB each), as well as the usual P95 small & large FFTs.

If you want to go even higher with the CPU, you might run into RAM limitations...so why not use 5:6?

That puts it @ DDR2-1020...you can then likely go down to 5-5-5 too.

See what's faster in Everest:
9x425 DDR2-1063 6-6-6
or
9x425 DDR2-1020 5-5-5


Once you get your final clocks decided on, then work on lowering voltages/timings.

For the RAM, see if 5-5-5-[12-15] is doable, or 5-6-5/6-6-5 (depending on which speed you settle on).

Make sure you tighten tRD (Performance Level) as much as you can stably.
You should be able to drop it to 8 @ your FSB currently, as long as you don't use 1:1 (that usually requires higher).

Clock twister will affect numbers in RAM benches...but be aware it can break stability in a hurry.
Moderate is likely the best you will get; unlikely though at higher speeds of RAM.
Lighter or Light will be probably what you have to run.

For the voltages, assuming you've already gotten vcore as low as is stable, you can trying lowering NB & FSB voltages a notch at a time till they become unstable.

You might be able to go lower than you'd expect...just remember to test stability each time you lower them though & makes notes.


I'm not so good at putting what i do for my OCs into easy-to-read words for others, but i hope this helps somewhat.

thanks for taking your time to explain it mate

i decided to stay on 425 X 9 while doing 5:6 1020

what i dont know how to change is the tRD? i cant find it on the BIOS?? is it possible called something else...

my ram ia doing 5-5-5-15-5-55-2T...

tRD aka Performance Level is located in the RAM settings area.

Look for Ai Transaction Booster.
Set that to Manual
You will then see Performance Level, which you can adjust lower.
As i mentioned, you your current settings, you should be able to do 8.
Be aware if you set it too low, it will not POST.
You can try 7, but that may not POST.
Pull-Ins have never worked for me on any of the P5Q BIOSes so i would just leave those disabled.

[davidkozat]

na they it doesnt not pass the benchmarks if i put 8... is there any realisticly performances improvement changing the number on the performance level??

[deaffob]

Yea it probably does more than changing your CAS, I can't find this article on Anandtech about it. It reduces the delay between NB and RAM if I remember it right

[davidkozat]

thanks mate but everytime i try to set a number it wont stay stable and by defaul it says 11 i tried my old ram as it seems to be far more stable and and it gives me fair better benchmarks i sued to be running 8 gig of corsair CM2X2048-8500C5C then run only 4 gig and still wouldn't be stable at the overclock now i thought i try my old 4 gig G.Skill F2-6400PHU1-1GBHZ and i found it to be far more stable and better overclocker... so i lost like 70 pounds buying the ram for nothing

[deaffob]

Haven't ran this mobo(P5Q-E) with 8gb but with 4gb the lowest you can run with 1:1 divider is 10PL(performance lvl) and 8PL for 5:6.

Same thing i've found at higher FSBs.

But if you are running lower, you can do lower tRD.

More relevant if you've got an unlocked multiplier to play with but worth a read nevertheless.

Q9550 E0 vs C1 which one is better for OCing??

[truehighroller]

EO is the best.

[deaffob]

I have a question about the GTLs. Are GTL values suppose to be giving totally random stability? Hmm I don't know if anyone understands that right. So let's say I'm 1hr stable with .61, if I move it upto .615 will I get the similar result or is it gonna be like 10minute stable and .62 will be 45minute stable. I am asking this because I'm OCing my 8400 to 4.5Ghz and up until 4Ghz I didn't need to touch my GTLs. Testing with every GTL steps will be a horrendous amount of job and I really wish they are not random cause I want to move up 2 or 3 notches at a time if let's say .61 is giving me 10 seconds stability.

One more question, if my ram is stable and I intend to only OC my cpu with multipliers (500 x *) do I even need to touch my NB and NB GTL? Does the cpu's OC get affected by NB at all?

Oh btw, Lee is the man

[cincyrob]

question guys. ihave the Q9550 EO. running it now at 3.83ghz 451 fsb
i have some mushkin mem ddr2 800 4-5-4-12. and im running it at 902mhz. this ram is takeing this OC great. but if i go higher i cant keep it stable... i hear alot of you guys talking about running at a different ratio than 1:1. i thought 1:1 is what you wanted to keep your mem at.??? i know i need some 1066 mem to get over 4.0ghz and stable but should i loosen that up and run say 5:6 ratio instead of 1:1. should i try to loosen up my mushkins now and try 4.0ghz? i know my CPU can handle it its just my mem holding me back.... yes i still havent made up my mind on which mobo to get still battleing between the P5Q Deluxe and the GA-EP45-UD3P

Clock for clock 1:1 gives you the best performance but with other dividers you can do lower PL and normally it's the cpu that can't do the high fsb.

With my Dual cores I hardly ever touched the CPU GTL's, when going higher you prolly need to increase FSB term voltage. If you start tweaking the GTL's it can take some time mate, it's just like that...
Quad users can't get around it, duallies with a tad more Vcore can prolly keep stability... not CPU is the same, same for each mobo/ram combo...

For the NB it could be that you can get away with it at the same volts, settings, could be that you need to increase it some... In general these boards love AUTO for the GTL's as they are well programmed... once over 550FSB I needed to tweak to get 24/7 or bench stability.

Try to see if they can do 1000/1066mhz 5-5-5-15 or 18, TRFC set at 55. Ease of setup I prefer the P5Q Dlx anyday over the P45 UD3's... for heavy quad pounding the Giga is better suited, though I don't like the coarse voltage increments... but that's my personal taste I'm getting the Maxmus Gene II for review, maybe hold of ya buy mate... board seems interesting

Clock for clock 1:1 gives you the best performance but with other dividers you can do lower PL and normally it's the cpu that can't do the high fsb.

Mmm P45 is quite different, it's far easier to stabilise when using a divider other than 1:1... eg at 500FSB , which one do you think is faster 1000mhz ram or 1200mhz rams ?
