:confused: Hey guys i bought my parts for my build over the last few weeks and unfortunately i ordered my RAM before my cpu (sandybridge) and motherboard
The ram kit i ordered is this one at 1.65 volts

http://www.overclockers.co.uk/showproduct.php?prodid=MY-048-GS&groupid=701&catid=8&subcat=1517

Ok so i know that for sandybridge its recommeded to use 1.5 volts, no higher than 1.65 so i know i should be ok but this is my first build and im a bit worried.

So in your opinion guys should i lower the voltage on this RAM i have to 1.5 ? or leave it ?
If so is it a simple as what this guy is doing in this vid?


Or should i just buy some 1.5 RAM like the Ripjaw X to be sure ?

Thanks again guys :)
 
All the SB overclocking guides I have seen say not to worry about the Ram.
If it is 1.5v, 1.65 etc. dont worry just set it to its correct voltage.
This is what was posted on a very good guide by Clunk.

Sandy Bridge has only been around for a short time, but sadly, there is an incredible amount of confusion regarding certain aspects of voltage adjustment. The information below, comes directly from Asus, Gigabyte, Corsair and Intel PMO (Platform Memory Operations), and to the best of my knowledge is 100% correct at the time of writing this. Of course, if any new information comes to light, I will update this section.

* Sandy Bridge does not demand only 1.5v modules, it will be perfectly happy with 1.65v modules too. If someone tries to tell you that you must have 1.5v modules, then they are either trying to sell them to you, or they have been reading misinformation, or both! Another point to consider here, is that in your BIOS, if you head to the memory voltage setting, and enter 1.5v, the text will remain white/grey, if you enter 1.65v, it will turn yellow, and it isn't until 1.73v that it turns red, so at the moment, I'd rest assured that 1.65v modules are OK to use, and I have had this confirmed by Asus, Gigabyte and Corsair so far, as soon as I hear from anyone else, I will update this again.

Thanks mate you have put my mind at ease.
 
the corsair xms3 is rated at 1.65v, but overclockers (after their tests) have now changed the description to
1600MHz RAM Speed, CAS 9-9-9-24 Timings, 1.40-1.65v VDIMM, Lifetime Warranty with Corsair.
my system would not boot into windows at 1.5v so i kept notching the volts up until it would, and so ive been running it at 1.58v which seems fine.

As previous posters have said, XMS3 is great stuff IMHO. Mine in sig runs rated speed at 1.26875V (yes that's not a typo...)
 
dunno how low I could take the volts on mine, but they're MORE than happy at 1.5v
(XMS3 2x2gb, bought just before the SB (official :p) NDA lift).

@OP: there's every chance that they will work fine, but I would return them under distance selling regs and get the newer parts, that way you KNOW they will be fine!

Thanks for your post man, i'm not sure what to do yet, When all the parts arrive i will make a decision then because i'm a little worried my cpu cooler may not clear the RAM anyway. ;)

My attitude on this is really as follows:

- There are lots of manufacturers selling 1.65v memory, many of which specifically labelling/qualifying it as "suitable for Sandybridge"
- These manufacturers have had the specs for P67 well in advance of release
- I don't believe these manufacturers would sell 1.65v memory if there was a fundamental flaw or risk in their use (dealing with support issues, potential class action suit, etc)
- People saying otherwise are probably pushing an agenda
 
Hi there

If its really an issue just set your RAM to run at 1.50v and you will find it probably does it happily at the rated timings. :)
