Our initial experience with G.SKILL has shown that this company is capable of producing high speed, high performance DDR modules to cater for the enthusiast market.
When we first reviewed their Extreme Samsung TCCD PC4400 1Gb Kit, we were impressed by the performance and overclockability it offered over its rated speed of PC4400 (DDR550) and at the same time the extreme latency it allowed at PC3200.
Today we will be reviewing another product from their Extreme Series. Promising more speed than their previous offering, this kit is surely to please overclockers out there. Introducing, G. SKILL’s PC4800 (DDR600) offering, the Extreme Series PC4800 512Mb Kit.
The G. SKILL Extreme PC4800 Samsung TCCD 512Mb Kit (model F1-3200DSU2-512LA) is a matched pair of 256mb Samsung TCCD PC3200 modules capable of running CAS 2-2-2-5 at DDR400 (PC3200) and an impressive DDR600 (PC4800) at CAS 3-4-4-8.
The G. SKILL Extreme Series PC4800 continues to utilize the latest advanced technology in product development. These Dual Channel Series modules are specifically designed for high frequency operation on Intel 865/875 or AMD K8 chipset based motherboards through the use of G.SKILL Samsung TCCD PC3200 2-2-2-5 SERIES HyperSpeed and ULN technology. These modules are handpicked and tested before they are shipped so you are assured that they will run at its rated speed.
The Extreme Series PC4800 512Mb Dual Channel DDR Kit is packed in G. SKILL’s usual rigid hard plastic see through container. You would barely know that its from G. Skill except for the small logo printed on the right side of the kit’s label insert. At the back of the insert is the obligatory instructions and warranty information. Opening up the included insert you will see the company profile and seperate sheet with the evidential testing results.
This particular kit is made up of 2 x 256mb Revision F 4ns Samsung K4H560838F-440 TCCD ICs. Handpicked, these modules have been tested to run at an extreme speed of DDR600 (PC4800) at CAS 3-4-4-8 and at extreme low latency CAS 2-2-2-5 at DDR400 (PC3200). These has been the fastest rated DDR modules we’ve received to date.
Like the first modules we’ve tested from G.SKILL, the Extreme Series PC4800 is absent of any heatspreaders. So if you want looks to go with your ram, you won’t have it with this number. Obviously though, this hasn’t affected its performance and overclocking potential.
As our Intel system maxes out at 281MHz FSB, we weren’t able to fully test the modules at their rated speed. Being handpicked and fully tested though before being packaged, we have no reason to doubt though that these modules won’t function at that speed. As reference, you can view G.SKILL’s own tests showing that they have indeed ran these modules up to PC4800 (DDR600).
For the overclocking test, we tried a variety of timings that the memory would work on. Below are the following CAS timings used:
CAS 2-2-2-5 CAS 2.5-3-3-7 CAS 3-4-4-8
The G.SKILL Extreme Samsung TCCD PC4800 (DDR600) Kit was tested at both DDR-400 and DDR-550 settings. For comparison, we used Corsair’s TWINX1024-4400C25PT 1Gb DDR550 Kit and G. Skill’s Extreme Samsung TCCD PC4400 1Gb DDR550 kit. We’ve also included results taken from the highest overclock of each kit. Note that we used only the fastest latency timings that each kit can handle at DDR400, DDR550 and DDR562. The memory was set to run at 1:1 synchronous with the CPU and with the vDIMM set at 2.6v. Testing was done under Dual Channel configuration.
This is only the second product we have reviewed from G.Skill and like what I’ve said in the first review, if G.Skill will continue to push the envelope to the limit, they will get a good following from both the enthusiasts and overclockers. So far, we are impressed by the performance, stability and compatibility these modules have provided during the duration of our tests. We were very glad the performance at DDR400 using extreme latencies picked up from these modules as that was the one thing lacking with their PC4400.
The Extreme Series PC4800 512Mb Dual Channel DDR Kit showed tremendous potential for overclocking. The ability to run at aggressive timings at high speeds is something that overclockers have been waiting for for a long time. Running CAS 2.5-3-3-7 at DDR562 is indeed quite an achievement. Although we weren’t able to test the modules at their rated speed due to hardware limitations, we are happy to know that it can go the distance with our current hardware. Running DDR562 synchrounous with the processor at FSB 281MHz FSB is not too shabby.
Again, G.Skill has continued to show what their products are made of. They have upped the ante by introducing a DDR600 (PC4800) part. With still a lot of systems running DDR1 memory, you can be rest assured that G.Skill will continue to provide the power users with their overclocking needs in terms of memory. The only thing to remember with this kit is that for some users, 512mb wouldn’t cut it anymore. However don’t despair as these modules also come in 1Gb kits. Hopefully the performance is the same. If you want just plain old fast DDR without the bling and the high cost, then the Extreme Series PC4800 512Mb Dual Channel DDR Kit is an excellent choice.
