Please help me! Biostar 965PT overclock failure :(

[pcbananas]

Hardware:

Intel Core 2 Duo E4300
BIOSTAR TForce965PT
G.SKILL 1GBx2 DDR2 800 F2-6400CL5S-1GBNQ 5x5x5x15
XCLIO GOODPOWER 500W
ARCTIC COOLING Freezer 7 Pro

Problem:
Overclock Navigator Engine set to Manual Overclock

CPU Voltage: 1.350
FSB T Voltage: Default (1.2)
MCH Voltage: Default (1.8)
Memory Voltage: Default (1.8)
System Memory Freq: Default (Auto)
CPU Clock: 233Mhz - I get a little over 2GHz but if i go anything higher, nothing!
PCIE Clock: Default (Auto)
DRAM Conf: Default (Set by Spd) 5x5x5x15
TWR: Auto TWTR: Auto TRRD: Auto TRTP: Auto


Anyway, I have made other small changes to CPU Volt, Memory Volt, and I have tried 333MHz for the CPU Clock. The only one that works is the one above. Could someone please help me?

Thank you!

I was having MAJOR overclock problems with the same Biostar board you have now. I will tell you what did help me though. Update to the latest BIOS, Disable all your Spread Spectrums, and note that most likely you will have gaps in the FSB that don't work(330-400FSB didn't work on mine, but 405 did somewhat stable.)

Anyways I am on Gigabyte DS3 now and love it. Although it does have some strange cold boot issue that is apparently common.

try setting vcore to 1.4v to boot. you sure vmch stock is 1.8v?? intel spec is only 1.2v....

up vdimm to 2.1v, and keep the 5-5-5-15 timings.

make sure pcie is locked. if 100 doesnt work, try 105 or 110. I use 110 on a daily basis for whatever added performance it may bring.

If there is option for pci, make sure it's at 33. spread spectrum to off. disable c1e and eist for now.

I almost got the biostar board and still might in the future, but these settings should be more or less the same across the board.

set to 350fsb and make sure mem is 1:1. See what happens.

If anything, set vmch to +0.1 or +0.2. It'd probably land you at 1.3 or 1.4v supposedly.

I believe my mistake was not realizing my ram mhz was going up as i started increasing the fsb. anyway, i followed your instructions except my MB does not have an option for PCI or the c1e/eist. I couldn't go as high as 350, but I was able to get 2.7GHz
i'm guessing my problem is that my ram can't go over 800MHz. Before with my original settings the ram was 932MHz. now is running at exactly 800MHz.

hmm, your ram is running at 800? Are you achieving 2.7ghz by doing 9x300? If so, you're using a 2.66x ratio for ram. Try to set it to 1:1 (2.0x) and see how high you can scale. That should allow you up to 350fsb and still run ram at only 700, while at the same time allowing you to run 3.15ghz.

If you wanted, you could run say 8x400=3.2ghz and have ram 1:1 at 800, or something like that.
