[GIGABYTE GA-P35-DS3L Rev.2.0] - General Overclocking Help Needed.

MZADotCom · Jan 8, 2012

First time posting, hope it's in the right area. As the issues touch on several components, I'm hoping for the best. If I need to relist elsewhere, please let me know & I will do so.

I built a moderately overclocked rig [CPU & GPU] a couple of years ago. It's mainly used for graphic design & some gaming [Crysis, Halo]. Have never had any major problems. Recently though, after upgrading to 8GB of 1066 RAM [max. on my mainboard], I've experienced a few random Windows shutdowns/restarts taking place when I've left things unattended. 99% of the time everything's fine. All the settings for my mainboard, overclocked CPU/GPU & RAM are right where they should be. So, looking to get some help with basic troubleshooting & fine-tuning to maximize my system.

The areas I need assistance with:

my mainboard & BIOS
CPU Vcore
FSBRAM ratio
Memory Timings

One of the main issues is the memory timings. At the BIOS, using the advanced BIOS settings [Ctrl + F1], I have it set to the recommended 5-5-5-15-52-2T timings, *BUT* CPU-Z shows them to be @ 5-7-7-20-68-2T. I don't know if this discrepancy is normal or to be expected from CPU-Z.

I particularly need help with the “FSB

RAM” settings, which are @ 5:8 now. Would like to get them as close to a 1:1 ratio as possible.

Screenshots of my BIOS & CPU-Z results are included. If I need to post any other info, will gladly do so.

Any & all help will be greatly appreciated. Thanks in advance.

... w/ all of your current settings. It then makes it unnecessary to have to scroll the entire page to view all your settings as screenshots. I'm not sure why you'd want to change the FSB : DRAM ratio to 1:1 at a FSB of 333MHz, since that equates to only DDR2-667 instead of the modules rated DDR2-1066. If you plan on increasing the bus past 333MHz to test for max. clock, then you can change the divider to a lower ratio like 5:6 or 4:5 to take the memory out of the equation. And w/ the timings set to 5-5-5-15-2T at 2.1V, try using a program besides CPU-Z like HWMonitor for example to view the timings from within the GUI.

Appreciate the quick reply. I got busy with work to reply sooner. Had I known about the BIOS template for my mainboard, would have used it. Thanks for the heads up.

FYI: Noticed that some of the info in the template for my mainboard is either missing or just plain different vs. what's there for me = the areas where I put down "N/A".

You bring up some interesting points. I've always gotten the impression that having a FSB : DRAM ratio as close as possible to 1:1 was ideal. But what you're saying makes sense & 1:1 would definitely not be “ideal” for the new 1066 RAM I purchased.

How do I increase the bus, exactly? Is that controlled by the CPU Clock Ratio/CPU Frequency/divider settings? I've definitely got to research this more.

Per your suggestion, I installed both the 32-bit & 64-bit versions of CPUID's “HWMonitor” @ my CodySafe thumb drive PC-in-a-pocket. Neither one shows any info about my memory. Everything else is covered, though. Curious, why would the RAM settings above require software other than CPU-Z? I've heard nothing but good stuff about it, but I guess it's not the most accurate for all configurations.

The goal for me, again, is to optimize my system's settings until I have to build a new rig in the future. Until then, I need all the help I can get.

Cheers.
