The Official OC (OverClocking) Thread!

Above 1.5V is known to be dangerous territory for 65nm CPUs, you're winging it on luck, so by the same reason I'd say abive 1.33V is dangerus territory for 45nms.

 

nah they can ship with a vid of upto 1.3625v so id say +0.1v would be about the vmax i would go.

looking around tho 1.3v seems enough to take them to 4ghz

 

I was under the impression 1.3625V only applied to the high end 65s...

a clan mate and i both bought the same proc from the same shop the same weeek, same batch# and pack date but my vid is 1.225v and his is 1.08v.

bugger.

 

sammorris,

Intel has changed the voltages on all the chips apparently! My E6750 box is clearly marked with 1.350v being the maximum voltage. Now they come marked 1.5V. The Wolfdale's were originally maxed at 1.276 or something right around that, and now they are marked 1.362v. My personal 6750 is, and has been running at 1.47 pretty much since I installed it, so I doubt at this point that Electro-migration will be a problem for me. I personally think that the revised specs have been upgraded to reflect more of the real world! LOL!!

I still wouldn't run a Wolfdale at 1.50v though! Time will tell! LOL!!

Intel Cuts Core 2 Quad Processor Price in Half, and other processors by as much as 30 percent.

In all, Intel reduced the price of fourteen processors, ranging from the mainstream desktop to its Xeon line for servers. The company also introduced several new models.

The most noteworthy reduction, however, was the Q6700, now priced at $266, down from $530. Intel also slashed the price of the corresponding Xeon processor, the X3230, in half as well, to $266 as well. Both chips run at 2.66 GHz, and include an 8 Mbyte cache. The company also launched the Core 2 Duo E8300 (6M Cache, 2.83 GHz, 1333 MHz FSB) at $163, and the Core 2 Duo Processor E7200 (3M Cache, 2.53 GHz, 1066 MHz FSB) at $133.

so how long before they revise the site again and raise the max v for the 45nm? a year?

i dont think i will go much above 1.4 for 24/7 clocks but i may for the odd bench run

 

Hey GM, the price dropped 10 dollars on the P5E. It's 160 now with free Shipping.

I'll keep everyone updated. Eventually they will realize people aren't buying enough and have another firesale.

 

the spec max voltage for my E3110 Xeon wolfdale is less than it's E8400 counterpart. max recommended voltage for my E3110 is 1.225 where the E8400 is 1.3625. my E3110 is currently running at 4.0ghz with vcore of 1.33v both OCCT and orthos stable.

I have read of ppl in forums taking both versions up to 1.4v+ with adequate cooling without any dire effects. intel may have up'ed the max voltage recommendation for the E3110 as well but I don't know for sure.

mine is rock solid at 4.0ghz. absolutely no BSOD's, reboots, or freezing.

 

Mort81,

I just got off the phone with Intel and after talking to a tech that actually knew what he was talking about, he said that 1.35v is safe for the 3110 and 1.5v for the other Wolfdales. Same thing with the E6750, don't go over 1.5v and you should have no problems He stressed that if you push the Xeon's voltage too high, it will develop problems that can't be fixed! ie:Electro Migration, as the electronic pathways will break down and ruin the processor!

Congrats on the new build, and may your MIPS be high! LOL!!

1.5V eh? Seems surprising given the early number of issues. I'll wait and see how things pan out. The Q9450 HAS come back in stock in the UK, so the stock control problems look to be slowly settling down, but since it'll be at least late summer before I can upgrade again, I'm in no rush.

 

sammorris,

More than likely it's just the newer ones that can take 1.5v. The E6750 would run at 1.5v right from the begining, or mine would be toast by now! LOL!! There were documented problems with the early E8300/E8400 with Electro Migration that were caused by overvolting but Intel has obviously cured that or they wouldn't have raised the limits.

Russ

 

Ah, so they were raised. That's confidence inspiring.
Is this also true of the Quads?

 

sammorris,

The Kentsfield's are all 1.50v, while the Yorkfield's are 1.3625v!

Russ

 

So no then... That's a shame.

 

i find that very strange, why would he say that the duos can take upto 1.5v when the xeons from the same range can only handle 1.35v. surely with the xeons being from the top bins they should handle the same if not more than the lowwer binned duos.

hey, he knows what he talking about. you sure he wasnt just a rep trying to sell more chips?

 

marsey99,

If it was exactly the same chip, I would agree, but some of the additional functions of the Xeon are better and larger file processing for the whole network, which may well generate more heat. The server chips are designed for 24/7/365, and are usually forgotten until something goes wrong with the system. Usually the ventilation where a lot of people keep their servers is less than ideal, and Intel wants them to live for a long time! It doesn't affect users like us because not that many people have their own server, and all the other instruction sets are the same! LOL!! BTW, Not all of the socket 775 Xeons are good for regular PC use and are only for servers, so read carefully before buying!

Russ

 

sam, you got links to them? (the Q9450)

See, I was on the right track, or a good one at least. I run one E6750 to 1.480 daily as 485x8 w/ a 1.632 PLL for almost 1 year (10 months) and a 2nd one 1 month later at 1.36v as 500x7 w/ PLL of 1.612v and this became my regular 4GHz daily on 500x8 in 5:6 DDR1200 w/ PLL of 1.632v @ 1.57v since October '08 They were clearly early batches and marked 1.35v on box. But like I said back then, this is an overclocking site, we overclock and overvolt at our risk. These arn't servers and not gonna be in service a year from now (not for me, thats for sure). My Q6600 is also doing daily 480x8 @ 1.488v and this is over a year old, but only 11 months as is. My P5K Deluxe was the 1st one to take it to the limit back in May.

Us AMD guys know what I'm talking about. You say 1.3, we go 1.5. I got 1.55v on my x2 6400+ BE right now (6 months). It handles 1.6v for testing. And how about them 90nm X38 OC'rs pumping 1.6v daily into a 1.35v chipset. Not me, mine only needs 1.52 max for 500x8 on 5:6 divider.

I'm waiting on a 65nm X48 now that I'm loving DDR3 and prices are dropping. DDR3-1800 to 2050MHz is sweet on 500x8 @ 1:2. Only my Gigabyte is set up on DDR3 for now so I shell see how it does. Cant wait to move it to ASUS Rampage Formula or DFI UT X48 (if they offer a DDR3 version yet).

Who here is overclocking new OCZ Flex II as 2x 2g kit in PC2-9200 to over 1200MHz? Or any like RAM to same speeds?

New RAMPAGE FORMULA guys (or P5E), hit me up if you need input on getting the most out of your new rig. You're gonna love this mobo.
