Kingston HyperX 512MB DDR PC3500: Enthusiast ram by Kingston? Yes, such a thing does exist, and we got a couple sticks and test them in a dual channel enviorment.

For the past few years, I've pretty much stuck with . Part of the reason is they have a good reputation of making some reliable memory, and considering I didn't change PCs all that often, I wanted ram that would last. Another reason is their ValueRam series was dirt cheap (at least here in Canada), and it did the job.

Thanks to VL, I have been bitten by the upgrade bug, and slowly, but surely I upgraded my box to a point where it isn't that embarassing to show off to the chicks. The question that ran through my mind a few months ago was what ram to buy? Why should I put cheap ram in a fast box? Why should I consider one brand over another? Why am I talking in questions?

Having never let me down, unlike one brand I tried out last year, I went back with Kingston. Luckily for me, Kingston released their , which believe it or not, is ram targeted at the enthusiast. Enthusiast ram, typically defined as faster than "normal" clock speeds, and fancy heatspreaders, used to be reserved for a few companies. You can now add Kingston to that list.

Specifications

- Designed and built by the world's largest independent memory manufacturer
- High performance DDR memory tested at speeds up to 434MHz
- CAS Latency 2 support for leading-edge performance
- HyperX memory modules based upon latest specifications and designs
- Kingston's memory chips were custom-packaged for Kingston and screened to support the rated speeds on multi-million dollar testers
- Backed by Kingston's reputation for quality and support
- Available in kits of 2 to meet Dual Channel architecture requirements


If you noticed in the specifications, Kingston makes the ram in kits of two for Dual Channel support. I want to let you know now that the two sticks I have were purchased separately. You can read Vipe's reviews to see the merits of Dual Channel Kits, but I've been using 1GB spread across two sticks on my nForce 2 for months, and I've never had any issues. Am I saying Dual Channel Kits are useless? Not at all, but I do think quality ram will work in Dual Channel mode just fine... at least mine does.

The Kingston HyperX PC3500 ship with some nice blue, aluminum heatspreaders. I pretty much share the opinion that heatspreaders don't really do enough to dramatically make a difference while overclocking, but they do get warm to the touch, so I suppose having some heatspreaders are better than having none at all.

On the heatspreaders, is a sticker indicating the ram type. We can see that the ram is rated for PC3500 operation, which is 434MHz. The timings are rated at 2-4-4-8-1 (CAS Latency 2), which is pretty good, though not great. Not to worry though, as the ram can do better, but those are the SPD settings detected in the BIOS, so we'll be fixing that when we get into testing.

Overclocking

The first test was to see if we could run the HyperX at its rated 434MHz, 2-4-4-8-T1 settings. This is always a good first step just to make sure your ram is working as it should be.

I decided to tweak the timings a bit since better timings result in better performance. Lowering the speed to 200MHz (400MHz DDR), I then moved the DDR speeds upwards, 1MHz at a time until we reached our maximum overclock. As we approached the higher speeds, stability was a concern, and we've had to increase the memory voltage up 2.7v to maintain stability. At 2-2-2-6, we managed a maximum overclock of 210MHz (420MHz DDR). You'll notice this is now 7MHz slower than the rated speed, but given the more agressive memory timings, this was the best I could manage.

The next overclocking test was to determine the best timings possible at stock speeds. At 217MHz, the best timings I managed was 2-3-3-7.

A 225MHz (450MHz DDR) OC was the highest clock speed we were able to manage while still maintaining stability at stock timings. I did try the same overclock again, and lowered the timings to 2-3-3-7, but the end result was a nice, steady beep tone from my PC speaker.

Therefore, in summary, here's our results of our best, and most stable, overclocks:

 
2-2-2-6
2-3-3-7
2-4-4-8
Kingston Hyper X
210MHz (420DDR)
217MHz (434DDR)
225MHz (450DDR)
