Problem Overclocking Q9000 on M17x

Hi everybody..

I have this problem since ever, but I want to ask what it is about. The problem is if I overclock any higher than ~2.26 GHz (I don't know the exact number but can't reach 2.3 GHz) the fans stop working.

I mean I can overclock as high as 2.3+ GHz but if I do that, the fans, all of them, stop working and temperatures go 90°C+ in bot graphics and the CPU. Is there a problem with BIOS, with processor, what's the problem? I see some guys with Q9000 who succeful overclock @ 2.4 GHz...

Thanks.

PS: I only have this problem overclocking trough BIOS, no problem with Nvidia System Tools, but NST freeze the system at windows start!

 

Are you using setfsb?

 

No I never use it. I just overclock in BIOS.

 

How are you doing it in BIOS? I have a Q9100 ES and have maintained 2.9 w/o issue but generally run it not overclocked since it's fine at 2.26 for everyday computing.

 

i have the same issue depending on the day mine fails between 2322mhz or 2232mhz

i think it has more to do with the reason why these cpu are clocked at 2.0 then any thing else they likely failed intel's test for the QX9300 and been locked at 6mb and 2.0 ghz

 

I am just rising the CPU fsb only, and leave the memory fsb at stock. 2.9 GHz thats a huge overclock going from 2.26 stock, I had not idea the Q9100 was that good.

Maybe. but it not makes any sense to me why the fans just stop working, the fans should be controlled by the CPU/GPU temperature only, I can't imagine why the cpu frequency mess with the fans. I was expecting the overclock being limited by BSOD or system inestability, but not limited by the functionality of the fans.

 

might be your psu power limitation my version of the limitation apear in the form of stutering and the fan sticking in a wierd mode for me

 

But some people is able to overclock their Q9000 @ 2.4 GHz... And it is the exact same power supply... and they stop there because BSOD only.. or the system doesn't boot, but never heard about the fans issue.

 

maybe it's your mobo have you ever updated your bios and what version are you runing?

 

I don't know if the motherboard has some limitation about overclocking. I updated the bios only once, frem A02 to A03, never updated to A04 or A05 because I only hear problems about them, something like A04 mess with power supply voltage, and A05 fix that issue, to I see no point of going from A03 to A05... what do you think?

 

Any ideas????

 

i''d try flashing to a05 and if it does not work i'd consider lookinginsidde the beast for what ever and possibly reseating the fans connector

if that fails to i'd eb considering a mobo replacement

 

Have you tried using throttle stop to raise the core voltage and increase stability?

 

The Q9000 is a locked processor so you can't increase the voltage on it. That trick only works on the Core 2 Extreme processors like the QX9300.

 

Ahh, was thinking it was an extreme for some reason. Maybe an ES would work.

 

unless you force the bios to do so ..... how ever it generaly lead to unstability

 

The thing is I just want to know if it is a normal issue when it comes about overclocking. But I am not sure.... this is the first time I heard about this issue. And I am not sure if I can ask for a motherboard replacement hence the overclock isn't part of the warranty.. I mean Dell in any case told me the Q9000 was able to reach the 2.4 GHz..

 

The M17x R1 isn't able of rise the voltage in BIOS, or any way ( I think)

 

Bump

I got a Q"x"9200 and have overclocked it to 2.85 with no problems. I dont think the locked or unlocked would affect the fans. like someone told ya' in a past post, try flashing the bios to A05. I would love to know if that worked for ya' so pleas dont keep us in the dark, and give us an update mate.

Hi, here some updates about my issue, I updated the BIOS to A05, but the issue remains. The maximum CPU FSB I can reach is 1219 ( 2285 MHz), if I go any higher, than ironically the GPU's fan stop working, but the CPU's fan work perfectly. I tryed 1220, 1221 FSB and higher and they all make the gpu's fan stop working. The weird thing is I can overclock with NIVIDIA SYSTEM TOOLS @ 2.35 GHZ or higher without any issues, NST don't make the GPU's fan stop working, so I have not idea what this is all about, maybe a BIOS limitation, but is crazy to tell GPU fans stop working, these can burn my cards if I don't actually detect the issue.

 

And I think the fan's connector is OK.. because it work if the CPU isn't overclocked any higher than 2.285 GHz

 

Tyranus, first off, it's nice to see a fellow Star Wars fan Secondly, I think your mobo must be, well, not bad, but not perfect either. I have the OC'd q9000 at 2.4 and it works fine. Like they said earlier, R1 is limited on how you can OC with our CPU...I only use the CPU for OCing, then raise the RAM a bit for kicks...I'm at 1280 FSB for CPU and I think 1065 or 75 for memory. Wish I had a good answer for you. I suppose it's possible Alienware changed motherboards during the production of the R1, I know HP does that sometimes, they used a Quanta mobo and an Inventec for my old HDX9000.

 

Yeah.. Lord Tyranus was a great sith lord!! ... about the motherboard, maybe you are right but I think it is something between the BIOS and the motherboard because with Nvidia System Tools I can push my CPU speed up to 2.35+ GHz with no fan issue.. But yes the motherboard seems to be the only problem here, but I don't think Dell is gonna replace it if I tell them I am not able to overclock as high as other user.
