Ram concern

yes thats right for 1.5v designed ram,then run it at 1.5v but if your using ram from x58 like me designed to run at 1.65v then it will be fine to run it at that voltage:D

I wish you luck with that.

Hopefully it's not causing deterioration of your processor.

A lot of the RAM being sold today is manufacturer tested at 1.65V but works fine at ~1.5V.

Perhaps you should try it.
 
Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMX8GX3M2A1600C9)
1600MHz RAM Speed, CAS 9-9-9-24 Timings, 1.55-1.65v VDIMM if it runs ok at 1.5v leave it at that.

What OC UK States for Sandy Bridge K Series CPU's

***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!
 
i did but get errors,been working fine so far,cpu @4.5ghz and 8gb of ram @1600mhz,its the same ram anyway just operates at slightly higher voltage,its the imc voltage thats more important imo


set to one click below 1.65v in bios

btw i also read overclockers said its fine to use your old ddr3 in sb

EDIT: i would agree that ram printed 1.5v run at 1.5v but ram rated 1.65v run at that

yeah i think your abit paranoid about 1.65v rated memory:p but if my chip goes pop ill retract this statement

It's not a case of being paranoid.

I'm just advising people to follow what's recommended.

As does everyone else on this forum who knows what they're talking about ;)

That's very nice but everywhere you look the recommendation is 1.5V +/- 5%.

People have actually discussed this with Intel and that's what's come out of the discussions.

~~~~~IMPORTANT SANDYBRIDGE OC INFO: Voltages & OC Guide!!~~~~~

Sandy Bridge max voltage *warning*

I believe the OP has 16GB Corsair XMS3 (4x4GB) DDR3 PC3-12800C9 1600MHz.

That'll run fine at ~1.5V, I know as I have the same RAM ;)

There may be no 'problem' for some people using 1.65V but there is for others so why do it if you don't have to?

Now go away :p

Edit:

I was right about the RAM :D

Apart from his typo.

No.

Intel say 1.65v ram is fine, infact here is some certified ram at 1.65v

http://www.intel.com/en_US/Assets/PDF/prodspec/ww02-2011-XMP-self-cert_Core-i5-BlueBadge.pdf

So where do they say it is not? Also where are the people breaking their CPU's from using 1.65v RAM...

Yes I agree the OP should run it at 1.5v, but there is no problem running sandybridge with 1.65v RAM

Not really.

I agree with a lot of what you post and most of it is good advice.

It's only the odd occassion where I disagree that I comment.

Keep up the good work :)

Same here, and you're definitely right on this issue. I'd never advise anyone to run their DRAM at 1.65v

i know what im talking about,its fine following whats recommended but for those with 1.65v rated memory and errors at 1.5v then i dont see what harm in running it at its rated voltage

believe me i know what im taking about

Yes.

People who build PC's using these processors have discussed this directly with Intel and the recommendation is 1.5V +/- 5%.

If you read the second link in my post you'll see there were early reports of CPU's dying as a result of using 1.65V for the RAM.

Presumably everyone has learnt now to use less voltage so the early failures aren't being repeated.

Good luck to anyone using 1.65V.

They may be fine with it but if the RAM will run with less there's absolutely no reason not to.

Keping on saying you know what you're talking about doesn't make it so.

And again you're stating the obvious.

Yes, try running the RAM at a lower voltage. If it doesn't work increase it a bit at a time and if necessary increase it as far as it's rated voltage.

If the voltage you end up at is more than 1.575V then you take your chances.
 
actually the max safe voltage is 1.575v,i think the safest way we all agree on is run ram at the lowest possible/stability wise voltage you can

im not going to argue with such a superior brain
