cegras Posted January 29, 2008 Posted January 29, 2008 Hey; I won't be able to try these things out until after I replace my 3850. It's been causing instability for me in games and as a result I'm backing off the overclock just slightly to see if I can stabilize things.

Zelig Posted January 29, 2008 Posted January 29, 2008 I've found that if it's hanging at the verifying DMI pool data, it's usually a problem with the memory. I had a horrible time getting my memory and dividers working nicely, the key settings seem to be the DRAM drive strength and DRAM data drive strength. If interested, here are my 24/7 stable settings for the 3800+ in my sig: [b]Genie BIOS Settings:[/b] [color=red] FSB Bus Frequency - 280 LDT/FSB Frequency Ratio - 4x CPU/FSB Frequency Ratio - 10x PCI eXpress Frequency - 100Mhz CPU VID StartUp Value - 1.35v CPU VID Control - 1.350v CPU VID Special Control - Auto LDT Voltage Control - 1.20v Chip Set Voltage Control - 1.50v DRAM Voltage Control - 2.50v[/color] [b]DRAM Configuration Settings:[/b] [color=red] DRAM Frequency Set - 180=RAM/FSB:09/10 Command Per Clock (CPC) - 2T CAS Latency Control (Tcl) - 3T RAS# to CAS# delay (Trcd) - 03 Bus Clocks Min RAS# active time (Tras) - 08 Bus Clocks Row precharge time (Trp) - 02 Bus Clocks Row Cycle time (Trc) - 10 Bus Clocks Row refresh cyc time (Trfc) - 12 Bus Clocks Row to Row delay (Trrd) - 02 Bus Clocks Write recovery time (Twr) - 02 Bus Clocks Write to Read delay (Twtr) - 01 Bus Clock Read to Write delay (Trwt) - 03 Bus Clocks Refresh Period (Tref) - 2560 Cycles Write CAS Latency (Twcl) - 1t DRAM Bank Interleave - Enabled DQS Skew Control - Disabled DQS Skew Value - 0 DRAM Drive Strength - Weak 4 DRAM Data Drive Strength - 1 (50% reduction) Max Async Latency - 8.0 Nano Seconds Read Preamble Time - 6.0 Nano Seconds IdleCycle Limit - 16 Cycles Dynamic Counter - Enabled R/W Queue Bypass - 16 x Bypass Max - 07 x 32 Byte Granularity - Disable(4 Bursts) [/color] edit: Fixed a couple settings.

elito Posted January 29, 2008 Posted January 29, 2008 its sad that i have a manchester core. it seems that the Toledo's are a better clocker. should've taken the toledo when i order mine..damn it, but idk what hit me in the head, that; at that moment when i was ordering my 3800 x2, i thought to myself the manchester was a better revision. arg~ but i believe the toledo's run a bit hotter than the manchester's?

red930 Posted January 29, 2008 Posted January 29, 2008 It's more of a luck-of-the-draw than anything. You may get a dud, you may get a star. It's not like you could've told when you bought the chip. My Toledo runs pretty toasty as well, but that's probably due to poor airflow in my case, which I'm going to fix pretty soon. I got mine to 2.7GHz at stock volts.

cegras Posted January 30, 2008 Posted January 30, 2008 Zellig: my RAM is actually running LOWER than 200 Mhz DDR when I tried for above 270. (used a 7/10 divider). The BE-5 chips top out at 222 mhz so if I want to go higher than 2.66 I need to use a divider. I have 2.75 stable but it just won't budge above that. : ) Share this post Link to post Share on other sites More sharing options...

I have 2.75 stable but it just won't budge above that. : ) Yeah, I wasn't talking about ram speed specifically, when the "FSB Bus Frequency" is high, dividers will "randomly" not work, even if the speed the memory is running at should be alright. Before playing heavily with the secondary ram settings, the ONLY dividers I could get working properly at high FSB settings were 1:1 and 1:2. Might not be worth the effort of going past 2.75 if you're happy with that though, my chip does 2.8 with under stock voltage, but I figured that the extra performance from another .1 or .2 GHz wasn't worth my time trying to get the ram dividers working happily.

I never had any problems with RAM dividers not working randomly or otherwise. My resulting RAM frequency was always exactly what Gogar's or A64MemFreq calculated it out to be. Can you expound on that a little bit? Share this post Link to post Share on other sites More sharing options...

I meant that with certain dividers, everything will hang or reboot after "verifying dmi pool data". It's not random, as in actually random, I just don't happen to know exactly what settings cause certain dividers to work or not work at different speeds. All my testing was done with 4gb of ram on this board, which may have affected what worked, and what didn't. Share this post Link to post Share on other sites More sharing options...
Darkorb Posted January 30, 2008 Posted January 30, 2008 Well. 270x10, 1.45 vcore 2.9vmem 4x512mb Kingston DDR400 Value ram 3-4-4-8 @ DDR425 Those are my settings, not as many settings as ur dfi's. Share this post Link to post Share on other sites More sharing options...
