Lanparty UT nF4 SLI-DR Expert help with timings

Recommended Posts

I don't really know much about ram and timings. I am currently in the process of overclocking and am a bit lost. I attached a screenshot of my most stable OC at the moment. (I have not tweaked it yet). http://img215.imageshack.us/my.php?image=overclockxc8.jpg

.Now I went into BIOS and there are so MANY options under the memory tab. I don't understand half of them. I wonder if someone could help me out on what to set them at. I have this ram = http://www.newegg.com/Product/Product.asp?...N82E16820231032 . I think that this would be pretty good overclocking RAM.

Well here is what my BIOS says under the Memory TAB.


Dram Frequency Set (Mhz) 166 5/6

Command Per Clock (CPC) Auto

CAS Latency Contgrol (Tcl) Auto

RAS# to CAS# delay (Trcd) Auto

Min RAS# active time (Tras) Auto

Row precharge time (Trp) Auto

Row cycle time (Trc) 07 Bus Clock

Row refresh cyc time (Trfc) Auto

Row to Row delay (Trrd) 02 Bus Clock

Write Recovery time (Twr) 03 Bus Clock

Write to Read delay (Twtr) 02 Bus Clock

Read to Write delay (Trwt) 03 Bus Clock

Refresh period (Tref) Auto

Odd Divisor Correct Disable

DRAM Bank Interleave Enable



DQS Skew Control Auto

DQS Skew Value 0

DRAM Drive Strength Auto

DRAM Data Drive Strength Auto

Max Async Latency Auto

DRAM Response time Fast

Read Preamble time Auto

Idle Cycle limit 256 cycle

Dynamic Counter Disable

R/W Queue Bypass 16 X

Bypass Max 07 X

32 Byte Granulatrity Disable 4 burst


That's about all there is. Now I don't know most of these. Does anyone know a good setting someone who has the same board and ram would be perfect. I am lost and don't want to mess with stuff I don't know about.

You really need to go to the overclock guide and do a lot of reading http://www.dfi-street.com/forum/showthread.php?t=28049 You can also go to the overclock datbase and find an entry with hardware close to yours and see their settings to get started. Mostly you need to read the guide and learn the about the settings and then spend time working on them till you get the hang of it.

What sre the model #'s of your ram? for instance nine is F14000USU2 2GHBZ this would help. I could cross reference it with the Gskill tech on xtremesystems forum. We need the model # Gskill xtreme doen't tell me anything I looked on newegg and well are they DDR 400 DDr 500. thanks

Ok so they are the value series [newegg link] where do you get xtreme from? F1-3200PHU2-2GBZX are the model #http://www.gskill.com/en/f1-3200phu2-2gzx.html at 2336 2.6 to 2.7 v Here you go check this out http://www.xtremesystems.org/forums/showth...05&page=1&pp=25 You will have to keep in mind that gskill Tech's only have an ultra -d board to do testing on but the timings should get you close.

I'd seriously be looking at changing your setting from Auto and set the options with the correct RAS, CAS etc. All you are doing at the moment is running your RAM @200MHz (using the 5/6 divider with the HTT @240MHz).


I jumped onto the Net and found a review of your RAM... here's the results for overclocking. Notice they drop the CAS back to 2.5 to achieve any overcocking and to achieve 250MHz, they up the voltage to 2.7v (from the default 2.6v) and increase the CAS to 3.


Hope this is of some help.
