I´m currently doing a small compare between OCZ Titanium Alpha VX2 PC2-8000 and Corsair XMS2 6400C3 memory kits.
I´m doing most of the testing on P5W DH but I´ll test these sticks on other Intel platforms too... ;) Can you say Zeu.. Cheese...

Are those VX2 modules having any coldboot problems?
I remember many users had coldboot when pairing them with Lanparty.
I owned 2 of them and neither of them had problems... but BE forums have mahy users reporting them.
Im running an Asus board right now, But no problems at all with cold boot.
Excelent moduals

If anyone is running these on a Asus P5w DH, can you PM me or email me your bios settings, would be a great help.
Many thanks

Well, there is not much to say...
Both, Corsair XM2-6400C3 and OCZ PC2-8000 Titanium Alpha VX2 are based on IC´s from the same manufacturer. The specific model of the ic´s are obviously different since the modules react differently to the latencies.
To bring up the differences without meeting the limits of the chipset, I decided to ignore the rated latencies and use much tighter latencies instead.
Setup:
Asus P5W DH Deluxe (Bios 0602)
Intel Core 2 Duo E6700 (B0 stepping)
Settings:3-2-2-4-4-6-7.8µs-28 (tCL-tRCD-tRP-tRAS-tWR-tRC-tREF-tRFC)
http://www.armada.fi/VX2-6400C3/Chart-3224.jpg
The discontinued Micron D9 rev. A, better known as "Fatbody" ic´s are still superior if you want to keep tRCD and tRP latencies at 2 clocks.
Settings:3-3-2-4-4-6-7.8µs-28 (tCL-tRCD-tRP-tRAS-tWR-tRC-tREF-tRFC)
http://www.armada.fi/VX2-6400C3/Chart-3324.jpg
The difference between OCZ VX2 and Corsair 6400C3 is very clear in this picture. The tRP latency seem to be very important for VX2.
Settings:3-3-3-4-4-7-7.8µs-28 (tCL-tRCD-tRP-tRAS-tWR-tRC-tREF-tRFC)
http://www.armada.fi/VX2-6400C3/Chart-3334.jpg
The overclockability of Corsair 6400C3 was held back by the cpu.
The maximum benchable frequency of the E6700 processor was somewhere around 3.5GHz. For some reason the 7x multiplier was very unstable even at 400FSB, while the 8x multiplier was rock solid at 440FSB.
Both of these kits can hit DDR1066 frequency with 4-4-3-4 latencies and 2.3V. Due the chipset limitation that is also the maximum stable frequency.
When the chipset limitation is removed by replacing the motherboard with one that uses ATI´s upcoming chipset, both of these kits can break DDR1200 barrier with 4-4-4-1 / 4-4-3-1 latencies and 2.4V.
If there is something that you would like to see regarding the compare of these two kits, please ask.
awesome work!!! thank-you very much for the comparison, interesting results from your kits. the only thing i could ask to see is some AM2 action but something tells me it just won't happen ;)Quote:

Good comparo Stilt! You're getting some pretty good results with those VX2!
However, SuperPI 8M (or 32M) does not stress the RAM enough. Could you post some Prime or Windows MemTest results at above 400MHz?
Are These Titanium Alpha's all using the New Micron Die ?
Clearly not as good as the old D9 but still good.
But is was the same with the Old School Bh5 and the new parts. Old ones where better.
Congrats The Stilt very nice comparison
I'm not sure if its new or not but my VX2 came with Micron D9GMH ICs.Quote:

yeah those seem to be the best ICs to get............Gskill is using the same ones on HZQuote:

@ The Stilt
Which ATI Chipset & board please?
Thats alot of voltage, I was able to get mine to 580mhz w/ 2.5v 4-4-4Quote:

Yeah... I saw your impressive clocks quite awhile ago. Could you help me some Systool AM2 Memory Timings and AM2 Memory Fine Tuning screenies, please?Quote:

It's either my crappy Orleans memory controller or the mobo (Infinity UltraII-M2). You screenshot will really help us out..
Also, is it Super PI 32M or Prime stable at 580MHz?
edit: doh, forgot you were talking about intel, not amd. my bad :p:Quote:
