douirc Posted October 15, 2006 Posted October 15, 2006 I'm stuck at 2.95 and could use some help. I haven't updated my sig but I have a watercooled X2 3800 Toledo on an Expert with bios 04.06.2006 from the website, and am considering Merlin's 10.07.2006. I've tried upping the voltage on the vcore all the way to 1.6V but still can't get it stable. I can't believe it's this difficult to go an extra 5 MHz on the FSB. perhaps I should have tried Merlin's before posting . anyway, thanks for the help! http://img243.imageshack.us/img243/745/settingssh6.jpg Share this post Link to post Share on other sites More sharing options...
Guest caffeinejunkie Posted October 15, 2006 Posted October 15, 2006 That picture is abosluetly massive you should shrink down to 800x600 as per the rules. NVM on the setting somehow missed the massive a64tweaker window Share this post Link to post Share on other sites More sharing options...

Guest caffeinejunkie Posted October 15, 2006 Posted October 15, 2006 Try increasing trc to 12 and bypassmax to 4x. Oh and does extra voltage on chipset/ldt seem to help any? Share this post Link to post Share on other sites More sharing options...
douirc Posted October 15, 2006 Posted October 15, 2006 Praz - thanks for fixing the link. I'll keep the images down to 800x600. caffeinejunkie - I've tried upping the LDT/chipset voltage by a few points in bios, but doesn't seem to make a diff. I'm not following you on the mem settings. actually, I probably shouldn't have even bothered posting my timings. The mem is only at 245 and these sticks are good for 280 3-3-3-8 @ 2.7V (although I can't get them stable past 260 on the Expert). I'm gonna give Merlin's bios a shot...maybe that will do the trick.

Guest caffeinejunkie Posted October 15, 2006 Posted October 15, 2006 Well the settings Im talking about affect the memory controller which can be key especially when your pushing higher HTT. Im saying in the bios change the Row Cycle time (Trc) to 12 and change Bypass Max to 4x. Also what do you have set for DDS and DDDS?

douirc Posted October 15, 2006 Posted October 15, 2006 Interesting. I didn't know certain memory timings could directly affect CPU overclocking. I tried changing Trc to 12 and Bypass Max to 4x but couldn't get into windows. I changed my voltages as follows: CPU VID Startup Value = 1.425 CPU VID Control = 1.425 CPU VID Special Control = 112.0% LDT Voltage Control = 1.40V Chipset Voltage Control = 1.72V My vcore is now 1.59V (in bios) and I can now get into windows, but as soon as I try something simple like loading cpuz it locks up. I don't know how comfortable I am upping the voltages any more. Also, DRAM Drive Strength = Level 02 DRAM Data Drive Strength = Auto One more thing, my memory is on FIRE and i don't know why. Mem voltage is only at 2.66V and they're rated for 2.8V. Everything runs fine if I take the cpu:mem to 260 1:1 at 2.66V, so I know they're stable. I just don't know why they're so HOT!?! Additional Comment: Honestly, I'd be satisfied leaving the cpu at 2.95GHz if I could get my mem running with the 180 divider (268MHz) instead of on the 166 divider (246MHz). I'm sure that would make a noticable difference in performance. It's driving me nuts that my SLI-DR could run them at 280 2.7V but my Expert can't get past 260.

Guest caffeinejunkie Posted October 15, 2006 Posted October 15, 2006 Well go back to what it was . Try changing DDS to level 7 and DDDS to Level 3. Have you tried the 180 divider with looser timings like 3-4-8-4? Share this post Link to post Share on other sites More sharing options...
douirc Posted October 15, 2006 Posted October 15, 2006 so I upgraded to the Merlin bios and I'm running 295 HTT with 268MHz on the memory with the lowest voltages on ldt and chipset. I haven't yet tried getting to 3.0GHz, but the memory thing seemed to work itself out. I do have one major problem on the Merlin bios. It won't recognize my SATA Raptor drive?!? what's even more weird is when i'm in "windows" (I use bartpe for testing) i can see the drive, but because i can't see it in bios, i can't tell bios to boot off the drive. not sure what to do. was thinking to copy the mem settings from Merlin and put the previous bios back on. anyone know how to fix not seeing the hdd?

farksy Posted October 15, 2006 Posted October 15, 2006 Hmm ... your temps seem fine so i'll drop back the divider to make sure it's not your ram in the way. Share this post Link to post Share on other sites More sharing options...
douirc Posted October 15, 2006 Posted October 15, 2006 ok, after some searching around i realized merlin disables a whole lot of stuff in the default bios. i turned on the sata connectors and now i have my drive back. now i'm just gonna work on getting to 3GHz with the mem at 273MHz. I think it has to do with the LDT and chipset voltage. Guess I'll just keeping playing with each until i find something stable.
