OCZ And Patriot Memory

Previous Next
11:50 PM - 01/19/2009 by Thomas Soderstrom

OCZ Intel Extreme DDR3-1600 CAS 8

OCZ’s recent release of DDR3-2000 memory didn’t make it in time for today’s comparison, but the company was able to provide DDR3-1600 with CAS 8-rated timings.

Perforated heat spreaders allow air to circulate over a much wider area, which should help keep this part number OCZ3X1600LV6GK, 6 GB triple-channel kit cool. Then again, the 1.65 V theoretical limit for Intel Core i7 processors doesn’t really create much heat.


A maximum speed for automatic configuration of 610 MHz (DDR3-1220) is among the lowest we’ve seen for DDR3-1600-rated parts, but the modules come with slightly better-than-average CAS 8 automatic timings. An XMP profile for DDR3-1600 CAS 8-8-8-24 at 1.65 V represents the true rating of the kit, but users without XMP-capable motherboards must instead enter all settings manually through BIOS.

OCZ provides a limited lifetime warranty with all memory products.

Patriot Viper DDR3-1600 CAS 8

The "LLK" at the end of Patriot’s part number PVT36G1600LLK accompanies all of its "low-latency kits" and refers to the 8-8-8-24 timings of this 6 GB triple-channel configuration. These good timings won’t break any records, but Patriot could probably win an award for the prettiest heat spreaders. The long cooling fins probably aren’t needed at the rated 1.65 V.

Patriot Memory, like its competitor OCZ, uses fairly low-speed SPD values for automatic configuration and instead enhances the performance at stock speed using lower latency. Overclocking is required to reach the kit’s rated 8-8-8-24 timings at DDR3-1600 and 1.65 V, but an XMP profile makes setup a little easier for owners of XMP-capable motherboards.

Patriot memory products carry a limited lifetime warranty.

Grate article!
What was always bothering me about ram reviews is how much memory speed/timing will really impact on system performance. I it is a lot of work I know, but it was never covered.

From Article :
Of course, we needed a Core i7 processor, but not just any processor would do. While most reviewers are stuck with engineering samples that only support DDR2-800 and DDR2-1066 ratios (3x and 4x base clock, times two), our retail sample supports data rates all the way up to 2,133 MHz (8x base clock, times two).



I could be wrong, but shouldn't it be ddr3 ? I'm not aware of i7 supporting ddr2?

Heheh, looks like it's been edited.

I wounder if amd will do quad channel with its am3 motherboards or even dual 128 bit channels. that would be cool. Just something to beats intels triple 64bit channels.

Mushkin FTW :D

Lattely, I have noticed that Cosair has slowely slipped down (*cheering*), it seems they have gotten way to comfortable and now their products are showing that. This isn't the first time I've seen a high-priced *high-performance* Cosair product get absolutely trashed in comparisons by cheaper brands.

Cosair is going the way of Sony and Dell. "We got a name so were not gona do any more work on making our products better, exept to make them cost more so we can have more money!"

Good info. Would have been nice to see at least one real world benchmark.

Anyone know the difference between the following
Kingston HyperX T1 Series Kits:
KHX16000D3T1K3/6GX
KHX16000D3ULT1K3/6GX

What does the UL signify?... would it benchmark the same as the former (which was tested in this article)?

'The current problem is one of voltage.'
I loled at that.. maybe it's too early in the morning for me :D

Interesting just how few people give a damn about DDR3 at this point.
I guess many are a: Not wowed by i7 like they were core2 and b: Laugh and the prices of DDR3 at a time when DDR2 is not only still very fast relative to the software/games on the market but is dirt cheap.

They may have changed the name.

The response I got from Kingston:
=======================================================================
Kingston part number KHX16000D3ULT1K3/6GX is a DDR3 PC3-16000 memory module running at 2000MHz.

Kingston part number KHX16000D3T1K3/6GX is not a valid Kingston part number. Did you mean to ask about Kingston part number KHX16000D3T1K3/3GX?
=======================================================================

Either Tom's had a typo, and this is really only a 3GB (1GBx3) kit, or it is not released for resale yet (e.g. the sales reps don't have that part number available to them). The *only* 6GB kit I saw had the UL designation.

I guess now you want a copy of the invoice? Tom's didn't make a mistake, but it's possible Kingston might have changed the part number after sending the kit.

In CPU reviews it is often pointed out that the overclockability of any particular CPU depends on the particular CPU sample, and that results may differ strongly between CPUs of the same model. Why does this not apply to memory modules?

nah, not harping on mistakes or anything, just that Kingston is saying they do not have a 2GBx3 kit with those series available.

Reason I'm asking: Building a new system this week and looking to purchase THIS ram (the Benchmark champion, Kingston HyperX T1 series 6GB kit per this article).

I know the article said you can't find this anywhere, I was merely asking Kingston for when this ram might become available.

Tom's,

But what about performance in areas that count? I want to know if DDR3 2000 gives me more FPS than DDR3 1066 in games (Crysis, COD: WaW, FC2, etc). Because what I've seen so far, the answer is no or very very little.

It does apply to memory modules, but to a lesser extent. If you overclock six sets of modules with identical specs, you usually get a varience of around 20MHz.

Because both are rated at 2000 MHz CAS 8-8-8 1.65V, the most likely scenario is that Kingston sent its test module set to THG first, then altered the model number BEFORE making them available. That would mean the original model number never even made it into the stocking system. Since that's the most likely scenario, I wouldn't have any problem buying the parts with the UL designation.

Wonderful. Nice Article.
I are preparing a XY chart with Price-Performance based on that data, to post here soon.

Now, This article need a second part, Real world benchmarck, and bus overclocking limits on the wonderful P6T Deluxe.
