Q9650 E0 Testing

[Scoobie Dave]

I had similar problems with mine on a Q6600, over 450 needs a big voltage increase which could be deadly on a 45nm chip, max stable i had was also 465

Why can upping the NB be deadly for a 45nm chip?

Why can upping the NB be deadly for a 45nm chip?

I think it's ok up to about 1.5 - that is if you have decent cooling.

I think he was referring to vFSB and vCore

Its the vtt's that are deadly and as i experienced, they need a good bump for high fsbs.
I've also seen 1.45Vcore kill them too although these shouldnt need that much.

 

[1kiwi]

you killed a chip using too much VTT?

 

[Happy]

Thought most people new that too much VTT degraded the chips

 

[tatts]

you killed a chip using too much VTT?

Quite a few have

 

[gurusan]

it will reduce the lifespan but people are far too paranoid tbh.

There's that guy on XS who started running a few folding machines about 2 months ago with E8500s at crazy voltages like 2.0vtt, 1.6vcore......and he's shut them off and restarted them to test both oc and stock settings and they are all still working just fine.

That said, I put the limit at about 1.45vcore on my chips and have never needed more than about 1.26-1.28 VTT.....and for my E0 q9650 I am not needing much voltage at all.... testing 4.288ghz 1.308vcore, 1.28VTT and seems stable so far after about 45min of prime and 1 hour of CoD4

killed my 9550 ES with 1.45Vcore & 1.4VTT

testing 4.288ghz 1.308vcore, 1.28VTT and seems stable so far after about 45min of prime and 1 hour of CoD4

Im amazed how little voltage these chips need to get a decent overclock.

Looking forward to playing with mine tonight.

 

[1kiwi]

Any more results guys - i'm thinking about 'downgrading' but until i see something like 4.4-4.6Ghz prime stable at < 1.5 vcore it's probably not worth it.

Cant believe i did this but here goes.

Just installed everest to see what volts im using and what a shock, it said my fsb vtt was 2V !!!!! Rebooted in a panic and somehow it was set 2V in the bios.

Will have to re-test mine now for peace of mind but i've been running that voltage for a week now and it has hasnt died, maybe some chips are more sensitive than others

 

[gurusan]

lol how did that happen!

 

[tatts]

lol how did that happen!

lol dont ask, Looks like i set the vtt to 2v instead of the dram but its been priming ever since with everything on auto so hopefully it hasnt done too much harm ...


Anyway, anyone got more results on these Q9650's?

 

[Nelly]

What motherboard you using? Best setting your bios manually, I think nearly all Asus motherboards use high voltages on Auto settings - the Asus P5Q Deluxe for sure.

Asus are pricks, setting high voltages with auto settings, no wonder everyones cpu's are dying.

LOL - note to self...

When Tatts put his Q9650 for sale in Member Market, must not buy it!

 

[benktlottie]

In Everest, where is the FSB VTT reading?

 

[tatts]

What motherboard you using?

Maximus formula funnily enough

Now the Q6600 has gone and the Q9550 is dead i wont be selling it

In Everest, where is the FSB VTT reading?

When you go on computer then sensor, down at the bottom it has voltage values & there all in there

 

[Scoobie Dave]

They are nice, i just wish my motherboard would hit 500FSB. I sort of fancy 4.5Ghz now 4.0Ghz is so easy


Run some stabilty testing today.

Hi Devious,

I was wondering could you do me a massive favour and post down your motherboard settings?
Just received my 9650 and want to know what sort of settings to use. . .
If you could help me out here it would be most appreciated!
