Little PSC DDR3 Challenge - G.Skill, Mushkin and Exceleram

No benchmarks, simply Memtest stability testing.

4 PSC dual-channel kits, aircooled with a 8cm 1900rpm fan, CPU also air-cooled. Shame that the real fun with these chips starts under cold :p:

Platform

CPU

Intel Xeon X3440 (slower i7 860)

MB

Gigabyte GA-P55A-UD5

RAM

• Mushkin Redline "Copperhead" 1600 6-8-6 (110 euro)
• G.Skill PI 2200 7-10-10 (159 euro)
• G.Skill PI 2300 8-11-8 (167 euro)
• Exceleram VX 2000 7-10-10 (133 euro)

Test

Memtest for Windows 100% coverage stability under
24/7 user sweet-spot timings of 6-8-6 ( ideal for maybe Clarkdale ) and 6-9-6
using stock voltage ( 1.64 Vdimm BIOS , 1,657 V DMM measured )

Consideration

This is only a rough round-up. OC for varies from kit to kit up to +-30 (60 DDR) MHz.
Motherboard over- or undervoltage. During testing usually, 0,2V voltage bump resulted in 10-15MHz (20-30 DDR) MHz stability-limit-raise
These are all retail kits, no samples or ES.
Prices inticated are just for relative comparison.

Results

6-8-6

• Mushkin Redline 860 MHz
• G.Skill PI 2200 890 MHz
• G.Skill PI 2300 875 MHz
• Exceleram VX 865 MHz

Hope this provides good info :toast:

Looks good buddy!

Wanna add these http://i50.tinypic.com/2cx8h3p.jpg to your collection soon, and clock Hyper like a hyperOCer ? :p:
These are looking better Marc, don't they ? :D

:up: nice job, thanks for sharing

Bill, stop killing me! :D

Hey man , thanks for posting in.

keep pushing it

To tease! :D

Now behave if you still want those :p:

my gskill ripjaws can run 915mhz 686

are u sure that u can't run over 900mhz 6 8 6?

1.63v

Lucky you, I am sure I can't. Give me your board and CPU and I'll test it. Also, watch the "real" voltage

real voltage is 1.632v

from bios is 1.64v

boh i don't know if my kit is very lucky or not, but I thought that gskill PI do more, the same kit can also sell 6 9 6 to 2ghz

You can find a complete scaling test of the PSC chips here and on the next 3 pages :)
