If you have a Dfi nf4 motherboard running some BH5 ram this may be of interest to you.
I recently purchased 2x512mb of Mushkin Redline XP4000, these modules are based on the Winbond BH5 UT memory chips and can out perform pretty much anything available providing they have access to voltage of 3.2 to 3.7.
On getting these module I started to overclock them to find there max overclock, they seemed to run at upto 510mhz with timmings of 2-2-2-6 at 3.3 volts.
I started to test for stabillity at these speeds with prime and memtest 86. All seemed to be fine except for the ram producing a single error in test 5,6 and 8. I started to lower the speeds to cure this error but they continued to error all the way down to 400mhz at all different timmings too.
This concerned me very much and I thought there much be a fault with the ram itself. I contacted Mushkin support about this and they sent my a pdf with instructions on exactly how to set up the bios settings on the Dfi nf4 motherboard, they said I should try these setting first before any RMA is issued and that I need to follow the setting to the letter.
The settings are as follows:
Mushkin Redline XP4000 test Parameters.
Genie bios settings.
Dram frequency set-200.
Command per clock-Enabled.
tcl-2.0
trcd-02
tras-06
trp-02
trc-08
trfc-auto
trrd-02
twr-02
twtr-02
trwt-03
tref-auto
twcl-01
dram bank interleave-enabled
dqs skew control-auto
dqs skew value-0
dram drive stength-level 8
dram data drive strength-level 3
max async latency-auto
dram response time-normal
read preamble time-auto
idlecycle limit-256 cycles
dynamic counter-disabled
r/w queue bypass-16x
bypass max-07 x
32 byte granularity-disable(8 bursts)
fsb bus frequency-255
ltd/fsb frequency ratio-x3.0
cpu/fsb frequency ratio-varies dependening on processor
k8 cool n quiet support-disabled
cpu vid startup value-startup may vary depending on processor
cpu vid control-set to default vid of processor unless overclocked, can ot be set to auto
cpu vid special control-varies depending on processor
ltd voltage control-1.3v
chip set voltage control-1.6v
dram voltage control- varies, usually set to 3.3v ( actual target is 3.4-3.45)
dram+ 03v if its not 3.2-varies
other noteworthy bios settings
thermal throttling-disabled
all unneeded devices to be disabled
Cooling
Standard practice is to use a 120mm fan blowing sirectly down onto the modules and the 4v mosfet area
Ok thats about it. I found that when I used these settings all errors in memtest stopped and it even allow for a bit more on the overclock.
I tried these settings on the Mushkin Redline xp4000 bh5 mudules and found that they worked great, I also would have thought that these settings would work on many other BH5 based ram with the Dfi nf4 mothboard.
I hope this help some of you guys as it did me
