Mushkin 2GB XP4000 Black Series – Test Results

Eldonko · 03-06-2006, 02:37 AM

This mem is not exactly new (been out since Aug/Sept 05) but it seems a lot of people have been expressing interest in it lately. I was given a kit to test and am going to share my results, suggested timings/tweeks, and my overall impression of the RAM.

Test bed:
DFI LP NF4 Expert SLI (BIOS E-1207)
FX-57
eVGA GeForce 6800GT
OCZ PowerStream 520W
Cooling - Custom H20

The RAM was very easy to set up, I just popped it in and it booted up right away @ DDR500, 3-4-3 and 2.65v. After that I went up in increments of 5Mhz testing w. memtest until I started getting errors then it was time for tweeking

XP4000 uses Samsung UCCC chips, week 52 in this set. UCCC isn’t like UTT or TCCD where it scales to some extent with voltage. The optimal voltage is actually less than 2.7v, about 2.67-2.69v. Higher than that the voltage causes instability. Just tweek and run memtest until you find optimal.

Secondary timings are also very important w/ this RAM, 1 setting off and you can have stability issues. See the settings below or my tweeker screenie to see what settings worked for me. *Note these settings are the TIGHTEST possible that still maintain stability at the speeds I am running the RAM. Some can be relaxed a bit, YRMV. Also what settings work for me may differ slightly for you because of system differences.*

Command Per Clock Enable
TCL-3.0
TRCD-4
TRAS-08
TRP-3
TRC-7
tRFC-16
TRRD-02
tWR-03
tWTR-02
TRWT-04
tREF-0780
tWCL-01
DRAM Bank Interleave-enabled
DQS Skew Control - auto
DQS Skew Value- auto
DRAM Drive Strength - Level 7
DRAM Data Drive Strength - Level 3
Max Async Latency- 8ns
DRAM Response Time - Fast
Read preamble Time- 5ns
Idle Cycle Limit- 32clks
Dyanamic Counter - Enable
r/w Queue bypass: 16X
Bypass Max - 07X
32 Byte Granularity - Disable (4 bursts)
Vdimm-2.67v, 2.71v in BIOS (Expert undervolts)

For the top end of the RAM, I managed to squeeze 280Mhz 3-4-3-8 2.67v:

How about some 3d action:

290Mhz 1M:

Same settings, SP2004 large FFT still running:

Your results will depend your system, OCing abilitys/skills, and a little luck. Overall I think this mem is great bang for the buck. A 2 gig kit that has a potential to hit these kind of speeds for ~$200 speaks for itself.

XP4000 UCCC (#991483) is in stock and avail at these places:

Canada:
Memory Express
NCIX
Kit-tronics

USA:
Newegg
Monarch

Go babay go! I have this RAM and have not tinkered with it at all yet - running @ 250 with most settings on auto. I'll be following your lead - so blaze the way and THANKS!

No prob.

If you have any questions, post em here.

I want to add that I just got confirmation from Mushkin that the sticks I was sent were picked randomly out of stock and were not hand picked. The mem was tested to 255 in dual channel before sending to me and that's it.

Few more mhz, slightly looser timings though..

That's a very cool set up. Good post as so many people are wondering how the 2gb kits are going to OC.

Mike.
