Finally got my qx9650 stable at 4.0ghz but have a question - Page 5

post #41 of 62
I wish I could talk you into selling your QX9650 on eBay for $700, then pick up a Q9650 for $350, get it to 4.0GHz - 4.2GHz, and have money in your pocket after all is said and done.

I can vibe with you wanting 4.0ghz! it's just a number im working on for my q9550 and 3.985ghz just doesn't cut it!! lol

There is NOTHING conservative about extreme edition procs expensive as hell, overpriced imo but that's the attitude you got. and if I bought one i'd clock the hell out of it, provided stable.

ALSO !!! be sure to play with the REf voltages try .63 and .61! those are crucial for quad OC! i got mine at 1.33 VTT ref .61 4.0 ghz at vcore of 1.38. I needed to up my NB volts to 1.61! so you may need some massive NB volts to get stable at lower vcore. just a thought.
There are also other points of view which points to protecting your investment.

I've also seen tons of people go to 1.55 and higher clocks, but with water cooling.

In my view if you have wc and can keep your chip cool (less than 60 load), than up the clock and volts. but if you can't, you shouldn't stress it with not only heat but also other voltage related depredation. (unless its a cheap chip your oc'ing the hell out of)

Seriously whats the diff between 3.8 and 4.0.

Mine can do 4.0 at safe vcore, some poeple can do 4.0 at even lower i've seen (which i'm jealous off). If you don't like the speed at a safe voltage, take rob's advice: sell it and buy a q9650 for the same price.

I feel for the OP on this situation. I know if I spent that mush $$ I would expect at least 4.0GHz. So it has to be extremely frustrating running just 3.8GHz. I would be fairly upset too.

if disabling LLC causes you to raise your voltages even further then you'd have to when it's off to compensate for vdroop, then I think you negate any possible safety gains.

the diff between 3.8 and 4.0 is mainly a pride thing lol. and it's quite important to some people. I cringed at only getting 2.925 over clock with my opty 165 lol. so close yet so far! haha. but seriously spending 1000 on a chip isn't really an investment imo lol. I mean, I find it difficult calling it an investment :-S

EDIT: I totally agree with ericeod, off it and get a 9550 or something, use the money to buy a bad ass video card or liquid cooling system. on off note Ericeod, your advice has been invaluable helping me get my 9550 to 4.0ghz! im in your debt

No problem, thanks. The way I look at it, I've been helped along the way by so many here on OCN. I know how it is struggling to get things right. Its only right that I pass on what I've been taught, and what I've learned. Without each other, this OCing thing would not be even remotely possible for many of us (myself included).

i dont see why running a qx9650 at 1.45v would be that bad considered ive seen others run the chip at even higher voltages for 24/7 use.

Its still a highly debated issue. I know 2 people personally who killed their 45nm CPUs by running 1.45v vcore. But there are others who say they have run 1.45v without issue. So it is a risk you will have to decide for yourself if it is worth taking. For me, I cant afford a replacement. And even though I am on water, I wont risk it. But I am happy with 4.2GHz at 1.304v vcore. I know I can go higher, but I would rather run the safer vcore.
