Patriot Viper II 'Sector 5' PVV34G2500C9K SPD

As it is usual, at Benchmark Reviews we love to show the whole SPD to our readers. These images help users to watch how their memory will work with and without an Xtreme Memory Profile when installing their RAM for the first time. Normally, brands write very light-loaded SPDs in order to maximize compatibility in every motherboard used. Have a look at CPU-Z SPD tab:


In this case, Patriot added 900MHz 6-6-6 and 1066MHz 7-7-7 JEDECs working at 1.5 volts. I actually find those values a little bit low, especially for this kit. Many motherboards support up to 1333MHz without issues, but I won't cry a lot about this since they already included a 2500MHz XMP working at 9-11-9-27 2T timings with 1.65 volts for users who just want to install their kit and set the XMP instead of taking some extra time for tweaking and manually set every parameter in the BIOS.


Just to corroborate, I always open CPU Tweaker and check timings, but this time I was rather confused when I saw the XMP shown with 10-12-10-28 Timings. It must be a bug and nothing else though...

While some users think testing stability at default settings can be taken as an insult to the brand, I normally test each DIMM to verify if there are any errors produced by shipping damages or any other stuff. Today, this is not just to prove that, but also to make sure I'll be able to reach 2500MHz 100% stable with the motherboard and CPU used as it's not an easy task, especially if you're not used to RAM overclocking.


Memtest 4.1 worked all the night without showing errors at 2500MHz 9-11-9-27 1T timings.

I'm just not sure that this RAM's value is there. Yes, you get faster performance settings, but at a whopping big price. The real world application performance for someone who doesn't O/C the heck out of their computer wasn't there either.
I do like the fact that the timings are on an XMP profile, so if you DO buy this RAM, you don't have to mess around much to set it up properly. XMP is a really good idea as far as I'm concerned. (I'm a 'set it and forget it' kind of guy)
I probably wouldn't go out and buy this RAM unless some wonderful thing happened to my finances and I found myself able to get the best of everything.
I know that Intel released an unlocked Core i7-875K processor recently. I wonder if the unlocked CPU would be able to benefit more from this RAM?
I am considering buying special RAM (8GB G.SKILL Flare) for the AMD 1090T hex-core system that I plan to build soon.

I keep forgetting to say this in my original comments, but this is a good review, Thank you.

This RAM is basically done for overclockers. If you don't overclock that much, just get a less expensive kit. All the i7875Ks I've seen have weaker IMC than the old i7 860s, so I din't really think there's a benefit with the unlocked CPU. Also, the i5 655K has a higher memory multiplier, but the i7 8765K has the same as the one I used (1600) as far as I know.

Qpi/Dram voltage past 1,35V can kill a I7.

I kill one with 1,6V, on Patriot viper 2Ghz 3-Chanel kitt.

THX, No More!

What? 1.35v?

The recommended max is 1.65v, there arent even that many kits which will run at less then that. Complete rubbish that your i7 was killed on 1.6v.

The max Dram voltage is 1.65V that's true. But I speak abaut the Qpi/Dram voltage,
that's Powering the Integrated Memory Controller.
1,6V set by XMP:)
When I try lower voltage, it cause NO POST.

Yes, QPI/IMC/VTT voltage at 1.6v is really high, but your kit really needs that? This one needs 1.35v or something similar depending on your CPU, and I've seen many people going above 3GHz (Memory frequency, of course) with 1.45-1.55v I really don't know why would you need something that high for a 2GHz kit.
