Full build review

1.5V +/- 5% is the official specification from Intel, so 1.575V maximum.

OcUK, in discussion with Intel, have stated that 1.60V is the absolute maximum for safe operation:



1.65V is a no, no if you value the longevity of your processor.

Everyone with a Sandy Bridge processor should be running their RAM as close to 1.5V as possible unless it'll actually run lower than that.

No,

Intel recommend 1.5v +/- 5% as that is the JEDEC spec for DDR3. We've already had this discussion. See here: http://forums.overclockers.co.uk/showthread.php?t=18363731

Pretty sure intel would say its 1.8v for DDR2 too, as that is the JEDEC spec. If you have 2.0v DDR2 should you run 1.8v? No!

Maybe you've forgotten where I linked to intel certifying memory that runs at 1.65v on sandybridge here.

If you'd like to have this discussion where I link several places on intels own website where they state 1.65v ram is ok on sandybridge then go ahead.

@ beejjacobs & horrorwood

I'm not getting into a debate with you about this.

Anyone who doesn't follow the current advice given takes their chances.

The current advice is stated on the product page of all the Sandy Bridge processors on the OcUK shop site.

***OVERCLOCKING GUIDELINES***

- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU
- Aim to keep temperatures below 70c underload if at all possible
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

Great, but I am quoting Intel.

Also your sig is misleading.

 

[Surveyor]

Also your sig is misleading.

My sig is quoting OcUK so if you have a problem with it take it up with them.

Ok, only if you can let intel know that their ram certification is misleading and they need to change it.

Oh and they also need to recall all of their p67 and z68 motherboards as the manuals say 1.65v ram is fine. Please let them know.

There's no need to be running RAM at 1.65V with Sandy Bridge as there are numerous kits available which work perfectly fine at ~1.5V.

If anyone wants to use 1.65V that's fine by me but just be aware you're taking your chances of sending your CPU to an early grave.

The only sensible thing to do is run your RAM at the lowest stable voltage.

I don't disagree, but if it needs 1.65V, then that is fine.

 

[Surveyor]

but if it needs 1.65V, then that is fine.

On that you and I will have to disagree.

 

[horrorwood]

On that you and I will have to disagree.

Do you disagree with intel?

 

[beejjacobs]

On that you and I will have to disagree.

So RAM rated at 1.65V (and tested) is not fine? The manufacturer is wrong!?

And the manufacturer also says this:

Contradictory advice but I prefer to go with the safest option and advise people accordingly.

Again, if you read the thread where OCuK got that advice I am pretty sure they asked for the voltage recommendation of DDR3 which is of course 1.5v

Have you even looked where I stated?

Intels own brand P67 motherboard manual on page 15.

I have even now taken a screenshot of that page of the manual

Again, you really think Intel are wrong?

 

[Surveyor]

Like I said, I really don't want to get into this debate again.

I really don't have the time or inclination.

If anyone wants to not follow the advice given by OcUK in conjunction with Intel then that's their choice.

If anyone wants to offer advice contrary to that given by OcUK in conjunction with Intel then that's their choice.

I shall continue to give the advice stated on the OcUK shop site (given after discussion with Intel) as it's the sensible thing to do.

It's bed time for me now so night, night all.

This is what I would probably stick with. I'd rather err on the side of caution, but each to their own.
