Overclocking on a D901C

Hi,

It's the first time I post in here (Sager and Clevo part of the forum).
I have just bought a D901C, here the specs:

- GPU 2x nVidia GeForce Go 8800M GTX SLI
- screen WUXGA 1920 x 1200 TFT (Glare-type SmartView) (zero dead pixel granted)
- CPU Intel® Core 2 Quad Extreme QX9650 - 3GHz 12Mo cache - Bus 1333MHz - 64bits - 45nm
- RAM 4Go SO-DIMM RAM DDR-2 / 800 MHz (2 x 2048 Mo)
- DVD-RW 24/8/4/2x Burner & Blue-ray Reader
- Hard Drive 200 Go - 7200 tr/mn - Cache 16 Mo - SATA 300 x 2 (RAID 0)
- OS Microsoft® Windows® VISTA Ultimate 64 Bits + Service Packs
- WIFI Intel PRO/Wireless 4965ABN 802.11N
- WEBCAM 2.0M

I would like to know if I can overclock my proc all the time or if it could damage it (to much heat...) ?

Thanks for your answers !

 

It's seems like there is no problem according to the post on SetFSB I have just read.

Sorry the answer was in front of me.

 

This isn't a direct reply to your question but it is related - if you're going to use SetFSB (or another program) to overclock the CPU then tbh you'd have been much better off with a Q9550. They are much cheaper then QX9650s - all you're paying for really is an unlocked multiplier.

I didn't know anyone was selling the chassis with QX9650s - I would have thought it'd be pushing it as the chassis is fine with a Q9550 but the QX9650s are 130W, the Q9000s are 95W........fans on max then

 

...and phazers on stun! :confused2:

 

I've a good notebook cooler so no pb .
Moreover I had a good price on the QX9650.
But I have to admit that I didn't look for a comparison between the Q9550 and the QX9650. Do you have a link?

 

Be careful though.

 

I have this comparison :

it's a bit formal but all the info is there.

A notebook cooler will only get better airflow to the intake fans, I echo RAMBO29 - be careful!

BTW out of interest what is the max anyone has clocked a core 2 quad in a D901C? I mean a stable 24h useage OC.

 

Would you please be so kind to post the reference here? I found a lot of information concerning overclocking the cpu on the M570RU, but could not find a successfull SetFSB overclock for the D901C.

Ordered a system a few days ago, and would be interested in OCing it

Thanks

 

So ok my question is again up. The post I was saying about SetFSB doesn't talk about the QC case.
So if someone has an experience..

In your document the QX9650 seems to have a good behaviour with heating.
Thanks for the link.

Sorry Cyberanto but I haven't got any answer for you.
Look at the last version of SetFSB and test all Clock Generator type.

 

So far Audigy has been unable to support the desktop Processors with his SetFSB... Notebook Hardware Control is working on this problem but it will still take some time... The only successful cpu oc for the D901C that I have read is the Dexgo Cpu mod, and he is missing in action....

Neil@Kobalt, has your group successfully installed a E8500 in a D901C? Are there still issues with this processor in the 9262 series Laptop?

 

i bet the battery will not last for more than 30 min... ;p

 

AlanP, yes we have successfully tested and ship with E8500s.

 

Thanks Neil, I have seen so little reported about this Cpu... Thought maybe their might be a Bios issue. Wonder if the upcoming E8600 will also work... I suspect that the E8500 and the yet to be released E8600 will be hampered by low release volumes...

 

The E8500s are currently very easy to get hold of (well, in the UK anyway) so I'm not sure why more companies aren't selling them.

 

@Neil:

Does the standard BIOS need to be modified in order to support the E8500?

 

No modding needed, the current BIOS is fine.

 

Why would there be, the thing barely eats any power(65w )

 

Fastest cpu speed available on this series Laptop. Wonder why there haven't been any performance ratings posted for this Chip as yet....

 

The last one we built got about 13,700 in 3DMark06 with Vista 64, SLI and 4GB RAM. I remember because that's pretty much what a Q9550 equivilent would get so the CPU speed advantage makes up for the lack of 4 cores (3.16GHz vs 2.83GHz).

 

Thanks for the quick response Neil. Do you anticipate any issues with the E8600?

 

Well even running at 3.33GHz I wouldn't have thought heat will be an issue as it'll still be 65W TDP.

I'll wait and see how testing goes - not long to wait now!

 

Huh? I thought that when you OC anything that heat rises with performance. This is why in the desktop world OCing requires better cooling.

 

When you OC anything heat rises with performance and voltage increases yes but the E8600 will run at 3.33GHz at stock so it's not overclocked.

My point is that for example a Q9550 runs at 2.83GHz and has a TDP of 95W so it dissipates more power than an E8500 at 3.16GHz at 65W. Therefore an E8600 will still theoretically dissipate less power than a Q9550 which has no temp issues in the D901C chassis.

 

Clear answer.
So as long as the Bios can handle 333 at a 10 multiplier, we are all set....
But Neil, didn't you indicate earlier, that there were some bugs initially, with the 1333 FSB Cpus?
Hopefully the new Q9650 will also work well. So many choices, so little time.....

 

I thought the Q9650 can not be overclocked in the D901C. Did someone relaease a BIOS that allows chenging the multiplier?

PL

 

pasoleatis,
The Qx9650, currently available, has an unlocked multiplier. The Q9650, not as yet released, is expected [Q3] to be about half the price, but the multiplier is expected to be locked.
And yes, in a D901C, it really doesn't matter as they all are locked snug as a bug in a rug.....unfortunately

 

I heard someone has a BIOS that allows the q6600 to be set at 3.4ghz.
You didn't hear it from me though...

 

hmm u sure its not the pin mod that dexgo did.??

 

Thats 3.0GHZ

 

hmm interesting.!! what bout the q6700 any news on that

 

I doubt it.
The modded bios takes into effect that the CPU is already 3.0ghz.
