Overclocking DDR: Truths and Misconceptions

By: Array

The crew over at ExtremeOverclocking.com have come up with some very important information about the many flavors of DDR RAM out on the market. Anyone interested in upgrading their memory should consult this guide before making their final decision.

 

With today's technology changing so quickly it is very easy to get behind. But when you hear about the fastest memory or CPU you think to yourself, "I have got to have it." Well, in truth, when looking at purchasing DDR based memory, there are a lot of things that you have to take into consideration... one of the more notable questions that comes up all the time is, "What is the fastest memory?" or "What kind of memory should I buy?"... What a lot fail to say are the other interesting points that one needs to know in order to maximize his / her system's performance, and at the same time spend money wisely.
Check it out @ Extreme Overclocking.

TwinMOS 512mb DDR400 Review @ Mikhailtech

By: Array

Mikhailtech have posted a review of a stick of TwinMOS 512mb DDR400 memory. We've got a stick currently being tested, from what I've heard - this RAM is fairly fast and reliable.

 

PC3200 modules have got to have a very good PCB in order to achieve such high speeds, 200MHz DDR, so the TwinMOS PC3200 RAM makes no exception. The PCB is designed with 6 layers instead of the usual 4 layers that other manufacturers use for their lower clocked models. The extra 2 PCB layers ensure the signal traces are cleaner and the memory will perform as it should. The DIMM I got did not come in a retail box, but in an antistatic bag.

"Has AMD lost the Plot?" @ DDRZone

By: Array

VooDoo from DDRZone has just posted an editorial (rant) questioning if the folks at AMD Australia have lost the plot, as he puts it. I tend to agree with what's being said being an Aussie myself. Although product shortages or delays is not a problem experienced by AMD alone. Click the link below and you decide what you think.

 

We have all seen the reviews, the hype and the pictures splashed across the internet lately about AMD's new processors the 2600+ and 2800+. We have seen the hype being generated about the new hammer range. At computex this year I spoke at length with AMD. both their staff manning the displays and staff from the Australian offices. We were repeatedly told everything is great, sales are booming etc.

Is All DDR400 Created Equal?

The Overclocker Cafe posted up what was originally supposed to be a DDR400 Prizematch between Corsair XMS 3200 C2 512 mb, Corsair XMS 3200 512mb, XtremeDDR PC3200 512mb, and XtremeDDR PC3200 256mb. What they ended up with was a best and worst DDR available.

The last time we had some Corsair in out test box we raved about having a stable ceiling of 176MHz. How does 194MHz for the XMS3200 C2 stick grab you? Someone hand me a paper bag to breathe in. Opening the settings even more to 2.5-3-3 2T gave us some action higher than Tommy Chong. And finally, we see the XtremeDDR break 200MHz. But only for the 512 stick. The 256 stick is left sucking wind as it hits the wall at 191MHz.

2 Memory Reviews

AusPCWorld is first up this time with their review of Crucial's PC2100 DDR 256MB RAM.

Crucial is known for being one of the industry leaders in PC Memory. The Company provides all types of memory for many different machine types and models. Today we take a look at Crucial's PC2100 256MB DDR module.

PC Stats are next with their look at TwinMOS' PC3200 DDR400 RAM.

TwinMOS 512MB PC3200 memory uses Winbond DRAM which has a "5"ns speed rating. As you probably read in our TwinMOS PC2700 DDR RAM review Winbond is making some awesome memory. Specifically, overclockers have been having a lot of success overclocking the Winbond "BH-6" DRAM modules. Well the 512MB PC3200 memory was using "BH-5" DRAM so I was getting pretty excited in terms of overclockability. Would this stick of memory be able to impress us as much as the 256MB TwinMOS PC2700 DDR did? Those are pretty big steps to fill.

Geil RAM looked at by Active Hardware

By: Array

We thought Geil memory sucked pretty badly when we first reviewed their DDR400 RAM which we reveled used overclocked chips. We were told by Victor from Geil this was because we were sent an engineering sample. Let's see what Active Hardware have to say about Geil's DDR400 and DDR433 memory modules.

 

Great Overclocking requires great memory -- memory capable of transferring information at higher clock speed and higher performance. One of the newest companies to offer high-performance memory is an outfit by the name of Geil. Geil has, for some time, offered such products as PC3200 DDR400, and PC3500 DDR433 DDR-SDRAM memory modules.

2 Memory Reviews

I've got 2 memory reviews here with the first from OCAddiction with a review of GeIL's top of the line performance PC3500 Memory.

Also, one of the largest barriers I have encountered wasn't maxing out my processor speed, it was not being able to run my memory faster. Typically there have been two reasons for this: one, the memory simply wouldn't run any faster; or two, the motherboard couldn't push the memory higher. To solve the first problem, GeIL has released 256 megabyte and 512 megabyte sticks of PC3500 RAM. PC3500 RAM is rated to run on a 216.666 megahertz memory bus or 433 megahertz DDR. That's over 100 megahertz higher than any JEDEC certified RAM!

3dXtreme follows up with their Corsair 256meg XMS3200 DDR Memory review.

Overall if you are looking to upgrade or if you are looking to purchase memory now I would definitly suggest spending a bit more and purchasing pc3200 like Corsair's XMS3200. Not only will it be usable on the kt400 motherboard but the heatspreaders keep it running cool and you should be able to overclock a bit further making pc3200 a very good investement choice.

2 Memory Reviews

AMDZone comes along first having tested out two 512MB sticks of Corsair PC3200 Cas 2 DDR400.

Corsair is at the top of their game releasing memory that keeps significantly outperforming the last. I notice that in the PDF they say that you can only run two sticks of this memory at CAS 2.5, but again they are being too humble as I was able to do CAS 2 with both sticks at the same time. Possibly not all boards are capable of supporting this speed. With enough voltage and a good motherboard you can easily do 400 MHz at CAS 2 with two sticks of memory.

Then along comes Extreme Overclocking with their look at GEIL's 512MB PC3500 DDR433 RAM.

GEIL recently released their PC3500 modules in the US. They are designed to run at 433mhz and use 5ns chips. None of the other major manufacturers have produced memory modules rated at this speed, so GEIL is the first to release PC3500. Will it run at the claimed speed, and how fast will it overclock to? Read the review to find out!

Kingston EPOC Memory Technology Interview

Mikhailtech has posted an interview with Kingston about their new EPOC (Elevated Package Over CSP) memory technology.

4. Are there any performance benefits in terms of stability, reliability and speed?
(Comparing the Kingston EPOC technology to stacked-chip module designs): EPOC technology ensures better thermal performance by keeping the rows of memory chips independently connected to the PCB and without chip layer interconnects. The air channel that separates the two rows of chips aids in cooling the memory chips; the memory chip rows and their independent bonding to the PCB also conducts heat away from each chip through the leads (TSOP) or the solder balls (MicroBGA) and into the PCB. The improved thermals result in better stability and reliability. In terms of electrical performance, the EPOC DIMMs meet the electrical interface timings specified by the memory controller's manufacturer. Shorter leads, reduced signal length and lower capacitance loading have also indicated improved performance.

Corsair XMS 3200 (DDR-400) CAS2 Memory Review

Hexus.net have a close look at Corsair's XMS 3200 (DDR-400) CAS2 memory module.

This Corsair CMX256A-3200C2 module does exactly what it states on its specification sheet, and then some. I felt comfortable running the memory at 215MHz (DDR-430) at 2.8v, I'm sure it will go higher once primed in a little. From a pure performance point of view, this is the best memory I have personally used.
