OCZ Tech is a company your hear about a lot. There's one reason why that is, they produce some of the finest ram existent. Though OCZ don't just make ram they make power supplies and flash memory, not to mention they take performance to the Extreme. You may have heard about OCZ before, but do you know who they really are?
OCZ gave birth to their great manufacturing company back in August of 2000. Back then DDR was the craze, and though it wasn't fast compared to today, OCZ still had the chance to put out some extremely fast modules for different setups. OCZ was founded by enthusiasts and they make the top gear for enthusiasts. They later became the ram manufactures we know as OCZ, they have their extreme warranties and high speed modules which just show off their knowledge.
In this review I will be looking at some of the newest modules OCZ has to offer. The OCZ EL DDR PC-4000 1024MB Gold Edition Dual Channel (2GB).
These nice modules came in the usual package OCZ ships there ram in. Though it was surrounded by bubble wrap, about 3 layer deep the bubbles were about 1cm tall.
- 500MHz DDR
- CL 3-4-4-8 (CAS-TRCD-TRP-TRAS)
- Gold Layered Copper Heat spreader
- Lifetime Warranty
- 2.8 Volts
- 184 Pin DIMM
- EVP® (Extended Voltage Protection, 2.9v ± 5%)
- ULN (Ultra Low Noise)
ULN stands for (U)ltra (L)ow (N)oise. This is a technology that uses various printed circuit board (PCB) techniques to reduce the amount of electrical noise that is present in all high-speed ICs. This results in faster and more stable memory.
What you get
Well I got what you would pay for, the two gold plated ram modules. Did I mention they were gold plated? now these modules don't exactly have the bling bling effect of LED's like on the Corsair modules. But they sure do look very expensive. Its all that gold.

OCZ chucked in some nice little freebies, some stickers and a cool looking poster (which has ram for magazines).
SiSoft Sandra 2005 ProfessionalCPU Arthithetic Benchmark - Dhrystone ALU
(measured in "mips", higher is better)
As you can see the timings really give the processor the added performance. The OCZ EL DDR PC-4000 swipes in the top spot with not very tight timings of 2.5-3-3-8CPU Arthithetic Benchmark - Whetstone FPU (measured in "mflops", higher is better)
CPU Arthithetic Benchmark - Whetstone iSSE2
(measured in "mflops", higher is better)
CPU Multi-Media Benchmark
(measured in "it/s", higher is better)
As you can see here over clocking the ram to its specified speed of 500mhz DDR, really doesn't help its every day multi media performance, it would be best to keep the tight timings at 400mhz DDR.Memory Bandwidth Benchmark
(measured in "MB/s", higher is better)
Heres where the dual kit really shows off. Nearly doubling the speed of a single stick setup, though a single stick of OCZ EL DDR PC-4000 over clocked at 500mhz DDR really increases single stick speed.
Future Mark - 3D Mark 05
Graphics: 1024x7683D Marks
(measured in "3D Marks", higher is better)
Hardly much graphic performance is increased when using these high performance modules.
This is a simple program which sets a array of 20,000,000 long sizes numbers. Each number is set to its array index. Speed is measured in seconds (Lower is better).
You can see the OCZ EL DDR PC-4000 really doesn't change as it is over clocked.
Half Life 2 :* Counter-Strike Source
Graphics: Game Picked (800x600)
Tested in the map "de_dust" with another bot, each session was run for 10 minutes.Half Life 2 :* Counter-Strike Source - de_dust
(measured in "fps", higher is better)
This is just a game test, performance will vary as the same scene is not repeated. The Mushkin did seem to take a lead possibly because of its low timings.
Battle Field 1942
Map: Operation Battleaxe
Graphics: High Quality (800x600x32)Battle Field 1942 - Operation Battleaxe
(measured in "fps", higher is better) *
All the modules produced pretty similar results.
The speed of the map load was also recorded.Battle Field 1942 - Operation Battleaxe (Load Time)
(measured in "seconds", lower is better) *
The OCZ EL DDR PC-4000 takes no time to load the map here.
Battle Field 2
Map: Zatar Wetlands
Graphics: Game Picked (800x600)Battle Field 2 - Zatar Wetlands
(measured in "fps", higher is better)
Battle Field 2 - Zatar Wetlands (Load Time)(measured in "seconds", lower is better)
As you can see the OCZ EL DDR PC-4000 loves this game, it will keep it loading quick and keep up the frame rate. The 2GB really helps here.(the Mushkin module is not a good performer in this game, it took over 2 minutes to load the map)
Over clocking is not really over clocking unless the end result is stable, and by stable I mean multiple passes of memtest86. I was able to get these modules running 275mhz @ 2.8 volts, anything higher wasn't possible to reach, not even going past 3 volts would make this ram go any higher. At 275mhz the ram was running on timings of 3-4-4-8. Some people have managed to clock these modules at 250mhz with timings of 3-4-3-8.
Timings 2.5-3-3-8 (lowest timings) 3-4-4-8 3-4-4-8 (highest OC)
Mhz 200mhz 250mhz @ 2.7volts (for stability) 275mhz @ 2.8volts
Memory is a ever changing field, so one day we might see low latency sticks of 512mb, the next day 2gb ram. What might puzzle people is that how large memory modules can keep low timings. Well if you really want to know, that's a question you can ask OCZ. One way might be the increase of voltage, but not with these modules, they can run on a stock voltage of 2.6 at high speeds of 250mhz and not to mention store 2gb. OCZ really have out done themselves here.
Some people might be saying right now, well they cant perform as responsive as other modules, do take into consideration that these modules weren't built for stability with low timings for servers, they were built for gamers and overlockers wanting both a fast machine and a over lockable machines.
Value ram really has left the market these days. Its good to see some Large fast modules coming out with a good price. My DFI had no problems running these, even with an older bios revision.
I would like to quote, "..is the perfect memory upgrade for memory-hungry Battlefield 2 gaming rigs." - OCZ Technologies. They really didn't lye when they said memory hungry BF 2 gaming rigs.
Also one last thing to mention before I give these modules the award they deserve. These Modules come with the OCZ Lifetime warranty, which is very very hard to void (unless you just take it past 2.9 volts for no reason).
OCZ EL DDR PC-4000 1024MB Gold Edition Dual Channel (2GB) takes home the 100% pure beefiness award, there's only one reason why! they are extremely beefy!!!
Pros ( + )
Cons ( - )
- Low Voltage requirements
- Reasonable Over clocks with low timings.
- Can reach Specified speed with no problems
- Gold Heat Spreaders
- Lifetime Manufactures Warranty
- Kit of Dual Channel Modules
- 2 Gig!!!!
- Your going to want a motherboard worthy of using these modules (Chipset can go upto or past 250mhz)
