kingdingeling Posted November 28, 2006 Posted November 28, 2006 I am STILL working on getting them up to 300MHz, they boot into windows all the way up to 315Mhz, but nothing is stable above 293 (OCCT) respectively 290 (prime95). I am running 3-4-4-8-1T, other timing will be atached in a minutes when I take a picture of my BIOS. I have pretty much tweaked all the timings to the death, but maybe some of you know something else to try. Voltages work best at 2.77 BIOS, or 2.8, but most people told me that is wrong for UCCC chips?! Share this post Link to post Share on other sites More sharing options...
Celcius Posted November 28, 2006 Posted November 28, 2006 (edited) Voltage looks ok, but you might want to try a hair below 2.6v (this is what mine liked). Also, is the ram actively cooled or passively cooled (and is it getting hot)? Here are the timings I used, they might help you out: http://img403.imageshack.us/my.php?image=ram55nh.jpg Edited November 28, 2006 by Celcius Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted November 28, 2006 Posted November 28, 2006 added BIOS screenshots. those settings look interesting celcius, I have always used TRWT 3, TRC 9-12 and TRFC of 14. Also, did your HZs work fine at TREF 3120? Mine are more stable at 3684 as far as I know Share this post Link to post Share on other sites More sharing options...
ccokeman Posted November 28, 2006 Posted November 28, 2006 I was going to suggest 3684 for youre tref but looks like you found that one. Have you set everything from DQS skew down manually? Heres an A64 tweaker shot of what i used but could not get stable. Share this post Link to post Share on other sites More sharing options...

caffeinejunkie Posted November 29, 2006 Posted November 29, 2006 Ewww whats with all those autos Give this a go: DRAM Frequency Set - 200=RAM/FSB:1/1 Command Per Clock (CPC) - Enable CAS Latency Control (Tcl) - 3.0 RAS# to CAS# delay (Trcd) - 04 Bus Clocks Min RAS# active time (Tras) - 08 Bus Clocks Row precharge time (Trp) - 04 Bus Clocks Row Cycle time (Trc) - 12 Bus Clocks Row refresh cyc time (Trfc) - 16 Bus Clocks Row to Row delay (Trrd) - 02 Bus Clocks Write recovery time (Twr) - 02 Bus Clocks Write to Read delay (Twtr) - 02 Bus Clocks Read to Write delay (Trwt) - 03 Bus Clocks Refresh Period (Tref) - 3684 Cycles Write CAS Latency (Twcl) - Auto DRAM Bank Interleave - Enabled DQS Skew Control - Auto DQS Skew Value - 0 DRAM Drive Strength - Level 7 DRAM Data Drive Strength - Level 3 Max Async Latency - 8.0 Nano Seconds DRAM Response Time - Normal Read Preamble Time - 6.0 Nano Seconds IdleCycle Limit - 016 Cycles Dynamic Counter - Disable R/W Queue Bypass - 16 x Bypass Max - 04 x 32 Byte Granularity - Disable(4 Bursts) Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted November 29, 2006 Posted November 29, 2006 caffeine, for the top settings I have used yours mostly already. The bottom ones will be out for a try tomorrow. The Expert BIOS doesn't offer to change the Write CAS Latency (TWCL), but you have it on auto anyways. What value does it give for you there? A64Tweaker tells me I have 1 clock(s).

hardnrg Posted November 29, 2006 Posted November 29, 2006 the only value it can run at is 1, nothing else works (ie. auto = 1), so some bios versions just omit it from the available settings i'm running my ram at 257MHz at the moment and have tried without success to get them to run at a faster speed because my options @ 2835 MHz cpu seem to be /11 = 257 or /10 = 284... i might have to try a 10.5 cpu multi to get an in-between speed... or try some of the settings you ddr600 boys are using hehe... keep up the good work!

kingdingeling Posted November 30, 2006 Posted November 30, 2006 I see a massive overclocking session this weekend, but expect some suicides this afternoon, I might even get some 320MHz screenshots from these babies in the attic now, OCing the holy crap outta CPU and mem here, SuperPI32M'ing thse babies right now at DDR600, everything looking VERY good so far (loop 9). Suicides to come, F@H load temps in here are like 33C, idle is around 20C. I feel some records are gonna fall caffeine! :D Share this post Link to post Share on other sites More sharing options...

Hehe, mine would probably do 600 too... if it wasn't my bottlenecked 260 CPU EDIT: That would awesome if that OC was totally stable at those insane speeds Edited November 30, 2006 by The Unforgivin Share this post Link to post Share on other sites More sharing options...
