Just got a new CPU from a competitor unfortunately it is a B3 stepping. I am overclocking it to 350*9 = 3150mhz @ 1.38v is this doable with this amount of voltage.

Also I need to download the Prime program that lets you run 4 worker threads to stress all 4 cores simultanously can anyone provide a link.

Thanks

I'd remove the competitor name sharpish as that's not allowed.

no 1.38V is quite low considering the stock vcore for B3 is generally 1.3V.

I ran the Prime 95 4 worker thread test and it failed quite quickly... now backed off to 3ghz 333*9 @ 1.35v and has passed the early stage of testing... hopefully this will run for a few more hours... I tried 333*9 at default voltage and it wasn't having it.

This CPU may actually be worse then the e6420 I was replacing which could do 394*8..

Any particular reason you bought a B3 when the G0 are so prevalent now?

Didn't have a choice at the supplier I was buying from... I assumed (incorrectly) that I would recieve a G0 from new stock, but I didn't...

If worst comes to worst and I can't get at least 3ghz stable then I`ll just have to flog it and either buy a E6750 or a get a G0 stepping Q6600 from ocUK.

I have a B3 coming tomorrow as well so will see what it can do.

I don't see why it won't even do 3ghz stable with a bit more juice.

I am now giving it 1.38125v @ 3ghz... it ran for 27 mins before one of the cores failed at 1.36125v so I guess it needs more juice.

I just hope it is now stable I won't go any higher then 1.38125v on my cooling thats for sure... its pushing it for temps now.

Oh how I wish I`d gotten a G0 stepping... if I can't get 3ghz stable then I`ll have to settle for less or change it for something else.

If it is brand new i'd just send it back and ask for a refund.

Can I do that seeing as its been used and the packaging is not in perfect condition....

I guess I could just say its faulty (not stable) or something and then they'd have to prove that it isn't.

I will see if I can't get 3ghz stable at 1.38125v then I will consider my options.

Not really, its also not very morally correct.

Just think if it arrived to you in the condition you are giong to send it back in would you be happy with that?

If you want an other chip flog this one and take it like a man :D
 
But the 7 day distance selling act only applies if the product is in its original condition? (i.e. box must still be sealed and unopened) I've done this a few times with RAM but that's because there isn't a seal on the box and there is no way they can tell if it's been used, so as long as box is in good condition it's fine.

However if the e-tailer advertised it as G0 but has given you a B3 then you definitely have the right to ask for refund or exchange for a G0. Otherwise you'll just have to sell it on and get another one I think.

You have to take reasonable care of the goods but it doesn't have to be sealed and unopened (there are exceptions, software is one), after all how are you supposed to inspect it if you can't open the package? It certainly is not intended for someone to return a used CPU that doesnt overclock "well enough". The stepping (well, product code) is marked on the box too so you could return under distance regs unopened and get a G0.

What makes you want to stay below 1.4v? Are you getting too much heat?

Yeah heat is an issue I`m running the stock cooler!!!.... 1.38125v @ 333*9 3ghz is working for me so far (just under an hour of Priming all 4 cores) I used to run my e6420 @ 3150 with the memory at 394 so I am already losing a bit of performance... this is balanced out by having 4 cores of course.

If I can get 3ghz stable then I`ll be satisfied, not happy, not exstatic but satisfied. If it won't do 3ghz it won't be becuase of heat it`ll be down to voltage, but there comes a point when you say enough is enough and you are afraid of toasting the thing.

I know these babies can run hot, 100C is boiling point and I guess thats when they start to boil, I know you should aim to keep the thing as cool as possible but I don't feel like jacking out more money on a decent cooler besides its the B3 and it runs hotter anyway.
 
Get yourself a decent HSF like my Tuniq 120 and you should be able to hit 3.25GHz like mine with a similar mobo!! :)

Q6600 B3 @ 3.25GHz idle:38-44C load:48-54C Vcore in BIOS=1.4875, V Droop = 1.410 :( Prime95 Stable!! :)

Hmmm CPUs are gonna be a bit of an odd one here... the distance selling act (which gives you 7 days) is so that you can inspect the item as if it was in the shop to see if its what you wanted... with intel (retail) CPUs atleast they are factory sealed and to be re-sellable would mean it was still sealed... if the seal is broken they'd have to sell it as B Grade which wouldn't be covered by distance selling regulations and they would be within their grounds to reject it.

I just checked the product description it says it is the 95W version but the product I recieved is not the 95W version. Therefore I should be elligable for a return regardless of whether it has been opened as the product was incorrectly described.
