Kingston HyperX PC4300 Kingston HyperX PC4300 Memory: We take a look at Kingston's latest HyperX kit, which bumps the speeds into the PC4300 territory.

Although a synthetic benchmark, it's a popular one, freely available if you wish to make comparison benchmarks. We will be testing the memory speeds at 250MHz FSB (to compare 1:1 against the OCZ), 266MHz FSB (the HyperX base rating) as well as our maximum overclock of 269MHz FSB.

You can see at the base of 250MHz FSB (3.5GHz) the original OCZ PC3700s actually slightly outperform the new Kingston sticks, I am sure this is due, in part, to the lower latency of the OCZ memory. Once we get to 260MHz FSB (3.73GHz), it is very clear that the PC3700s do their best at 3.5GHz, having to relax the timings to ensure a stable overclock is the culprit here. The OCZ stops cold at 260MHz FSB 1:1, and even at that, it isn't every boot that gives me enough stability to run every test. In fact, there was not one single time the OCZ PC3700 could boot into 260MHz FSB and run for 12 hours, but this is to be expected of memory rated at 233MHz.

PiFast

A good indicator of CPU/Motherboard performance is PiFast version 4.3, by Xavier Gourdon. We used a computation of 10000000 digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory. Note that lower scores are better, and times are in seconds.

Time in Seconds, lower is better

Now we start to see the advantage of tight timings when overclocking. The OCZ continues to outperform at 250MHz FSB but once you gain a little momentum on the front side bus the HyperX shows its strength and overcomes nicely.

TMPGEnc MPEG Encoding

Video encoding is a taxing chore, both on Memory and Processor; we will be encoding a 150MB AVI file to MPEG2. For the AVI to MPEG2 I used a bitrate of 5000k/Sec, as this is the midrange for a DVD, which is typically between 1000k/Sec to 10,000k/Sec. I used a frame size of 720x480 (DVD Std) and 16:9 NTSC. Note that lower scores are better.

Time in Minutes, lower is better

At 250MHz FSB, there is a negligible difference, but crank it up to 266MHz FSB and beyond, and we almost shave 15 seconds off of the encode time from the PC3700 memory. Realize that this is a very small AVI file, a typical AVI I pull off of my MiniDV camera is in the range of 6 to 7 Gigabytes, and that does not encode to a full DVD, it usually takes 20GB of AVI to encode to 4.4GB DVD using the above settings, just how much time have we shaved off now? (Using basic math it comes out to ~30 minutes).

PCMark 02

Another synthetic benchmark that is freely available if you wish to make comparison benchmarks. We are only going to be looking at the Memory score, as the other results are not what I am reviewing today.

Memory Score, higher is better

We see the same linear improvement we have seen on most of the tests here, the only thing that stands out is the jump the HyperX made from 250MHz to 266MHz, a 217 point deficit to a positive 80 points, not bad…

Final Words

Brook's $0.02

is known for it's quality ram, whether you go the ValueRAM route or the high performance HyperX. One thing is certain, you will not be disappointed. The ability to go beyond 260MHz FSB stable is good, and to reach 269MHz FSB with that same stability is welcome indeed.

Scott's $0.02

When it comes to our final overclock, this ram did well enough when you consider the fact that at 266MHz, this ram's rated speed, we are already 66MHz above the CPU's FSB (assuming a Pentium system). However I do have to remind folks we have seen both Corsair and OCZ PC4000 kits get to the 270MHz mark and beyond, both kits being cheaper than the HyperX PC4300 currently and not to mention the PC4400s doing 280 and above.

The thing with the PC4300 from Kingston is that it is rated for 266MHz where as (obviously) the PC4000's are only rated for 250Mhz, so you do take the chance that you won't get the same overclock from them as we have seen. You also have another price point thats lower than PC4400 kits, but at close to the same speeds. If you can't afford or don't want to pay the kind of money for a PC4400 kit then PC4300 makes for nice compromise between the PC4000 and PC4400 kits.

Hubert's $0.02

Well, I think both Brook and Scott have some valid points, but there are a few things I'd like to add as I have a couple of these sticks cooking in my rig right now. Simply put, Kingston validates a specific speed, in this case 266FSB, but your mileage can certainly vary when it comes to overclocking and tweaking. I didn't have much more luck overclocking in my Albatron PX875P Pro, but I did manage a 271FSB at 1:1 and 276FSB at 3:2 at 2.8v.

If you're going to be running at PC3200 speeds, in which case we've always recommended lower latency modules, you CAN tweak the HyperX PC4300. At PC3200, I managed 2.5-3-3-5 timings, which isn't super, but it isn't too bad either.

The price is higher than some PC4000 kits, but one thing to keep in mind that this kit is guaranteed to hit 266FSB, whereas PC4000 modules getting there are a bit of a crapshoot. It is cheaper than PC4400 kits, and you do get a lifetime warranty with Kingston products. Something to keep in mind.

Pros: Solid Performance and Overclock, Good Looking Heat Spreaders, Wide range of support with the PC4300 over the PC4400 kits.

Cons: Labeling could have been better on the actual memory, No further overhead with increased VDDR or ratio.

Bottom Line: Kingston have produced a quality kit here that won't let you down, but be aware you may have problems if using an ABIT AI7, and that you may be able to get similar speeds from cheaper overclocked PC4000. If however you want guaranteed speeds over 265MHz but don't want to pay out for a PC4400 kit, then this stuff is for you.
