I'm testing a 2GB-kit of Kingston Hyper-X. I began testing this on an A64 ZNF3-250 but was held back by the Chaintech disaster. I droppped it in my Asus P4C800Edlx, with 3.0E, and sort of as a joke raised the FSb to 250FSB (1:1). OMG it booted ran, and Sandra gave me 5900MB/s! All at just 2.75V, so I bumbed it to 2.85V (P4C800Edlx limit) and 255FSB was fine, but not 3DMark stable. Now I have to back track, because overclocking Prescott is tricky, and the D-VID feature must be respected, or it fry your mobo power circuitry.

I'll try disbaling PAT, and/or Hyperthreading, but that's not ideal. I'm switching waterblocks from the RBX to the Cool-Cases CC-Magic (99% silver sections), this and some spanking the NB should get this memory stable at 550MHz, 480MHz and 500MHz however; are still prretty nice for 1024MB sticks, given it's a PC3200 part. I think Kingston has found some Samsung IC's or something really special, but I'm not tearing these babies down. I like em too dang much. Below attachments are Aida READ at 240FSB, and Sandra UnBuffered at 240FSB (both 1:1) both at just 2.75VDIMM, raising to 2.85V didn't allow me to tighten the latencies. At 200FSB it runs 2.5-3-3-6. I'm bvery happy. Here's link to my site with some more info on this ksBrainstorms.

Well I have some benchmarks same sysytem same speed, except the comparative memory is Corsair Twin-X1024 3200XLPRO. The latencies are slightly tighter with the Corsair, so it may not be a truely accurate compare, but the Kingston results should be that much more impressive.

Below are attachements Science Mark 2.0 STREAM Benchmark from the Memory bench run at 240FSB 1:1. In both instances the memories were run on an Asus P4C800Edlx/3.0E combo. Same PSU, same cooling, same VDIMM, DIMM's 1,3, same graphics card, same PAT timings.

The only difference being Kingston is run at SPD which equates to 3-4-4-8
and the Corsair is run on manual at 2-3-3-6.

You can tell the difference because the SciMark STREAM bench with the CrystalCPUID Real Time Clock (multi & CPU speed) tag represents Kingston. Corsair scored approximately 200MB/s greater bandwidth over the Kingston. Given the Corsair is Low Latency memory running at significantly tighter timings, I'd say this bodes very well for Kingston.

I read about these samsung chips over at anandtech yesterday and find them to be pretty interesting since they seem to be a lot lower in price than the other competition in this performence range. do you know if kingston has changed over to the samsung chips for all its KHX PC3200K2? I wouldnt mind getting some 512 sticks if thats the case ^^.
