GeIL’s High Performance Copper Thermal Compound is a nice gift to the purchaser of this memory kit.
I tested the Ultra Platinum PC4200 533MHz Dual Channel DDR Kit from GeIL on an ASUS P4C800-E mainboard, in the dual-channel mode, having selected 2.75V memory voltage. Our Pentium 4 2.4C processor can speed up to 300MHz FSB and thus suits for testing any modern DDR SDRAM. I set up the highest frequency and timings first. Then I was reducing the timings, questioning the stability of the memory in the synchronous mode. Before presenting you the results of the tests I want to show you the information written into the SPD chip of the tested modules:
Strangely enough, the SPD timings are much higher than the specified 3.0-4-4-8 combination. Well, let’s check out the right numbers by testing GeIL’s Ultra Platinum 4200:
The memory doesn’t disappoint us at all. It considerably exceeds the recommended frequency and is stable at 285MHz! We evidently deal with memory of the first category here that can work at very high frequencies with rather high timings. If you lower the timings, its operability degenerates greatly – you can see that by the frequency drop from 275 to 230MHz on the transition to 2.5-3-3-6 timings. The memory wouldn’t start up with the minimal possible timings (2.0-2-2-5) at 200MHz, and I didn’t check it out with these timings at lower frequencies.
