San Diego 4000 voltage?

t31os · 28 Jul 2006 at 18:36

I was reading about the San Diego 4000 today and am to understand it comes in 2 flavours, 1.3 - 1.4vcore stock and 1.5 stock.

Which ones are OCUK stocking?.........anyone know?

I'm considering giving myself a performance boost by swapping out my Venice 3200 for a San Diego 4000.

Of course with the intention of OC'ing.

I'm reading a lot of posts suggesting it'll hit 3.0 on air, so the lower vcore chips are going to obviously be better for this.

I have 2.5 on the venice pretty easily and she's been dead stable for a while now.

What do you guys think?...... switch to a 4000 San Diego for a boost or not so?

I was under the impression all current san diego ones are 1.35v stock. The older clawhammers may have been 1.5v stock, the FX55 certainly was

My venice runs quicker then my buddies 4000 clawhammer in all benchies we tried.

If the san diego is better then this i'll be happy.

I did some further reading, looks like stock is 2.4, not sure on vcore yet.

Curious as to wether it would be worth buying it since the venice runs quite nicely and on paper the san diego doesnt look much better at all.

Comments anyone?

The 4000sd's should clock up to 2.8-3.0gig with a bump on the vcore but as your 3200 is currently at 2.5 do you really need an upgrade??? The real world performance gains arent going to be huge so its hard to say if it would be worth it or not. Just depends if you really just want to say you've got a chip that does say 3.0gig or not.

Thats my point, if its not a considerable amount its a waste of money.

Thanx...

Think i'll leave it for now.

Thinking about it it's a hard one to call. Fair enough your 3200 is @ 2.5 but thats the equivilent to a 3700 or 4000 @ 2.3 due to the size of the cache. Now I did find a nice gain going from stock, 2.2, to 2.8 that i'm at now, so if you can get 3gig out of the 4000 then that would be quite a step up.
For a quick test run super pi on your pc and see what you get. At stock I think I got around 36/37 seconds, at 3gig i can do it in 29secs so you can see the difference from that.
Sorry to confuse you more, just might be worth it after all.

If you were going to upgrade id get the X2 3800+ for £108. Assuming you sell your 3200+ for £40 youve got dual core for £68

t31os · 29 Jul 2006 at 12:43

Does 1M superpi in 37secs.

Think i'm quite happy with the venice, the other chips seem to be more hit and miss as to wether you get a good clocker. I'm still thinking about another cooler to, i brought the current one for silence more then anything then get excited about clocking and couldnt help myself. I think i push this one some more though, its only ever been the ram that held it back.

Buy myself a nice widescreen 19" instead i think.

I'd tell you more but i'm buying from a competitor.

Isnt OEM's San Diegos and Retails the luck of the drw between San Diegos and Clawhammers?

leeb · 31 Jul 2006 at 16:06

Pretty sure the oem 4000+ chips are all San Diego. Mine certainly was.

Got it running at 3GHz and my SuperPI 1M time is 33secs if that's any use to you t31os.

The OEM's are not only 20 quid cheaper, but advertised as San Diegos.

Don't get the retail edition as its pot luck & if you get a clawhammer, you can't send it back.

Add a Freezer Pro heatsink to the mix and delivery and its still cheaper than the retail box excluding shipping.

Should be receiving mine any day now.

so what is the max `s safe volts you can put into 4000 sandy . :confused:

Cyber-Mav · 31 Jul 2006 at 22:58

depends on cooling. most will say around 1.6v on air, 1.65v if on water.

i personally on air would not go more than 1.55v

Reality|Bites · 31 Jul 2006 at 23:42

These Oem 4000+ cpus do seem to run hotter than my old 3700+, At 1.45v i'm running hotter than I was with 1.6v running through my 3700+

yes at that voltage level heats a big problem on Air.

Just a thought but maybe you havn't re-seated the cooler as good as you did on your 3700???

i think they do run a bit on the warm side, my 4000 from the same batch idles at 37-38 and is 47-50 under load (1.45v). My pc is in the hottest room in the house tho

Exactly the same as my 4000 (@ 3GHz, 1.45v).
