Never got around to mentioning my oc’ing attempt for my friend’s MicroFly build but did have some “fun� with it!

Finally had gotten around seeing what I could wrench out of the 4400+ a the biostar Tf7025. In looking for guidance it seems this mobo is the “redheaded stepchild� to the Tf7050. Could find plenty of guides, modded bioses, and general oc’ing information on the 50, but the 25 defiantly seems to be in the shadows.

First I down loaded the latest bios (then) from Biostar (N68SM116) and using the Biostar utility it was a piece of cake. After that it was oh well. My usual set of testing / monitoring software: cpu-z, spdfan, clkgen, orthos, SuperPi, Prime 95, and OCCT, but did do any bench mark stuff, yet.

When setting up the bios, the first thing that got me was I had to leave all of the memory stuff in auto just to get it to boot. After playing around for a while got things “to work�. Just don’t ask me to duplicate it!! The following is the final results………..

The only values show are non-default, everything else has been left at default.

Mobo: Biostar Tf 7025-M2 / Bios N68SM116
CPU: AMD 4400+ Brisbane (CAA4C 0725WPDW) w/ zalman CNPS8700
GPU: MSI NX8800GT OC (Dual Slot version)
Memory: 2 x 1024 Corsair CM2X1024 – 6400C4

Power Management Setup:
K8 Cool'n'Quiet: Disable

PC Health Status
Shutdown Temperature: 60C/140F

Overclock Navigator Engine
Manual Overclock
CPU Frequency: 266
K8<->NB HT Speed: 3x
K8<->NB HT Width: 16 up/dwn

DRAM Configuration:
DRAM Clock:……..677
TwTr:………………3
Trfc 0 for DIMM1:…105ns
Trfc 1 for DIMM2:…105ns
Trfc 2 for DIMM3:…105ns
Trfc 3 for DIMM4:…105ns
Twr:…………….…..6
TrTp:…………….….2
Trc:………………... 24
Trcd:………………..4
Trrd:………………...4
Trp:…………………4
Tras:………………...12
CL:………………….4 (located elsewhere)

NPT Fid Control:…...11X
Timing Mode:………MaxMimClock
Memory Clock:……..DDR677
DRAM Command:….2T
CPU Voltage:……….+0.250v (1.47v)
DDR Voltage:………2.15v
NB Voltage:…………1.24v

This has resulted in the following:

Highest ClkGen with 8M run of SPi….

275 X11 @ 677 2T = 3.024GHz http://valid.x86-secret.com/show_oc.php?id=354147

Best stable backed up with 12 hour run of OCCT……..

266 X11 @ 677 2T = 2.926GHz http://valid.x86-secret.com/show_oc.php?id=356878

While the native muti for the 4400+ Brisbane is X11.5, the bios only goes up to X11 so I was leaving it in Auto. However quite by accident found out I could get higher results at X11!!
