Corsair Platinum 1.5v vs 1.65v

post #1 of 8
Thread Starter 
Looking at these two sets for my new build and wondering if the price difference is worth having the extra headroom the 1.5v kit would offer. I'm more interested in my CPU overclock, but would be nice to have the option to OC the RAM at lower volts if wanted.

Unfortunately this isn't the best of times to be buying RAM as it's so expensive, yet I'd say it's a good investment going for the better 1.5v modules. They are most probably made with a newer manufacturing technology, which is what allows it to run at 1.5v at such high speeds, akin to those Samsung 'wonder ram' low voltage modules everybody talks about.

What CPU do you have ? I would definitely go for the 1.5v ones if you had an Intel SB / IB / Haswell Core i5 /i7 CPU. 1.65v is the limit for those really.



Edit: also, the timings on Amazon's page are wrong, here are the correct timings from Corsair's site, the 1.5v modules are better:

I've got the 4930k. From what I've seen RAM has been overpriced for the last 3-4 years, so it's just one of those things if you want to buy what you want. I spent $260 for my 12g Dominator GT kit 3 years ago...

Yeah, unfortunately. 2011 and 2012 were the best years to buy DDR3.

I bought my kit in the first half of 2012, before the prices started to rise, but it should last me quite a while.

I don't know if you noticed, I edited my last post with the correct timings for those modules, the 1.5v ones are better.

For the i7-4930K I'd definitely go for 1.5v.

Yeah, I noticed the 1.65v timings were incorrect on Amazon. Thanks for including that. Will probably bite the bullet and get the 1.5v kit....I'll hate myself later if I dont rolleyes.gif

I share that sentiment.

I also made sure I bought the 1.5v 1866 Mhz modules back in 2012 even though they were more expensive than the 1.65v ones. No regrets. thumb.gif

1.5V version is based on Samsung 2Gbit D-rev (like 2400C9, 2600C10 and 2666C10 kits) while 1.65V version is most likely Hynix CFR (same stuff all makers put on 2800C11 and previously on 2666C11).

This. I currently run an 8GB kit of the 2133 1.5v Platinums clocked to 2666 at 1.65v CAS10
