Q9450 OC / Temps / Settings

[carepolice]

I am ashmed, i can get stable system (IBT, Prime, Linx) whit 1.28 Vcore and 3,6Ghz but in many games that i play, game crashes and says "**** stopped working" no bsod, no reset it just crashes to the game.

What can i do?

[Singh400]

Sweet voltage! nice clock singh!

Thanks Finally.

CPU-Z shows vcore at 1.200 and then goes to 1.208 on load.

I'd also memtest86 it, cpu stability isn't the only overclocking concern.

With the new 0605 Bios on P5E3 Premium I am now able to break my 495FSB wall. I am currently testing 507FSB and will post some results once I'm done. Here are some shots at 503-505FSB with memory running at 1617Mhz and 2016Mhz:

Hi guys


It's been a long time since I was last in here. Has anyone else managed to get a Q9450 Prime95 stable at 4ghz yet?

Your welcome .

[Singh400]

Your welcome .

The only place I was going wrong were my GTL refs, they were complete out-of-the-normal. I could probably get the volts down a bit more. But if it ain't broke, don't fix it right?

[truehighroller]

I am on my Q6600 right now and don't know where to start with it yet .

[Earzz]

Well, it don't matter. Only got 2 hours of prime before a thread crashed even without vdoop. I guess I found the optimal vcore for 3.5 (1.275 bios).

Atleast you are getting somewhere right now, i think you can reach 3.7 or 3.8 with your cooling.
Give it a try, my guess is that you need slightly more then 1.3 VCore in your bios and just leave the rest of the settings the same as now.

thats a graphics card related crash, lower you 4870 OC

[carepolice]

thats a graphics card related crash, lower you 4870 OC

Okey ill take a test

[mutang]

do you guys recommend to upgrade from a Q6600 to an Q9550?

Or is it better to wait for the mainstream intel nehalem?
does nehalem support ddr2?

[carepolice]

If its not about money get a E0 9550 DO NOT BUY A C1

no ddr2 for nehalem. IMO unless you go to q9650 your not gonna get the high clocks to make the jump worth it in the long run.

[mutang]

Thanks, I'll stay with the Q6600,then will wait a bit longer to see if prices will drop for the Q9650.

Nah, I've tried. I can't boot in to windows above 440 FSB, it was the same with my Q6600. Anything above 430 FSB (even with low multi) gets squirrelly. At 425, I had random lockups even with 1.375 Vcore and 29 hours of prime.

is there anyone with Q9450 and Abit Ip 35 pro i need some gtl adjustments help

[Cob]

Hard to tell since every chip is different, but I had my GTLs set to 72 at 3.8ghz for my Q9450 in the IP35 Pro.

But it's a case of trial and error.

[Vatos_locos]

ok i just wanted to see how high we can go :p mine runs better with 80 @ 3.8 but i was thinking that it might is too high and i asked

Hello crew, wanted to get some input/thoughts on these settings so far. Dont think i'm going to push it any further due to the fact 3.6 requires volts of 1.33 to get stable, as well as, push it to ~72C on the hottest core running IBT

CPU: Q9450 @ 3.4 ; MB: Asus P5E Deluxe

I don't see any problem in going to 3.6ghz at 1.33v and 72c. Tho you won't really notice the difference between 3.4ghz and 3.6ghz tbh.

Another my test with Prime95:

Have you tried loweing your vcore for 3.4 a little more? I agree 3.6 is hard to achieve, alot more tricky than 3.4.

I don't see any problem in going to 3.6ghz at 1.33v and 72c. Tho you won't really notice the difference between 3.4ghz and 3.6ghz tbh.

Re: sig. Nice OC mate, is that your 24/7? Or just for benchmark purposes?

Another my test with Prime95:

Honestly! Some people get all the good chips. Only can run my chip at 3.4 at that voltage. Damn you!

[Cob]

Re: sig. Nice OC mate, is that your 24/7? Or just for benchmark purposes?

She Folds 24/7 @ 3.9ghz and about 1.41v. The extra 100mhz for 4ghz isn't worth pushing so far over 1.4v.


She benchmarks at up to 4050mhz

[DrPain]

wow, nice temps!

On another note, anyone have any experience with this chip on a 790i board?

I run a Asus Striker2-NSE with the 790i , took a bit of play but had it running stable at just under 4gig , the temps were amazing low 30's on water. Scored 19854 in Futuremark '06 on 9800GTX in SLi config' much better chipset than the previous offering from Nvidia.
