E5400 + GIGABYTE GA-G41M-ES2L
I'm facing difficulties achieving a consistent stable overclock on this board. After removing the chip from my ASUS P5Q SE/R, I understand its constraints, but I'm not reaching the same performance. The Gigabyte G41 includes built-in graphics which might affect overclocking. I configured PCIE at 100mhz, FSB at 320 mhz, and multiplex to 11x for a target of 3.5ghz. On my other system, I managed an OC of 3.7ghz, indicating this board isn't pushing the chip as much. The Vcore is set at 1.4 volts, with a RAM ratio of 3:5, and everything is properly configured. These are the standard settings. I've experimented with lower OC levels, but even a small increase causes the system to crash before Windows loads.
Does the use of onboard graphics affect the process of unclocking?
The FSB speed on the board is specified, and different chips have different frequencies. Since the board supports a higher frequency than the Q9550, it can accommodate that chip.
the wall on that board is usually 300, but that's not accurate. As tekknyne mentions, the G41 works well with faster 45 nm chips. It's true that with these chips, the board isn't very good at overclocking. I own two G'byte G41s that can handle speeds above 360 MHz. The graphics on the board don't affect the overclocking process. Your RAM ratio suggests you're overclocking your memory. In BIOS, turn off Auto Memory Settings and set the system memory multiplier to 2.0. Then your memory clock should show double the FSB frequency. With a 200 MHz FSB, that means your memory clock should be 400 MHz. Keep in mind, because of the high internal multiplier, you don't have to push the FSB much beyond 300 MHz for noticeable overclocking.
I see what you did there. I’m familiar with tweaking this chip on my Asus board, and adjusting the FSB to memory ratio is simpler there. On this gigabyte board, the DDR ratio numbers are 2.66 or 3.00, and each change affects the DRAM frequency.
It’s true that even on my Asus board I’d tweak FSB and DDR settings before using CPUZ to confirm the actual DRAM speed.
Thanks for confirming the graphics should not be a problem. I assumed it was my mistake, but I’ll review the DDR settings and start with basic timings.
Nonsense. As tekknyne mentions, the G41 works well with faster 45 nm chips. It’s true that using them limits the board’s overclocking potential.
I own two G'byte G41s that can exceed 360 MHz.
Graphics cards don’t influence the overclocking process.
The RAM ratio suggests you’re pushing your RAM too much. Adjust your BIOS settings by turning off Auto and setting the system memory multiplier to 2.0. This should align your memory clock with twice the FSB frequency.
With a 200 MHz FSB, this would mean a 400 MHz memory clock.
Keep in mind, a high internal multiplier means you don’t need to significantly increase the FSB for noticeable gains.
PCI 4x won’t change the overclocking much, but a 4x slot slot won’t be very helpful either.
i have an MSI g31m3-L motherboard and I'm unable to push the e5400 beyond 240 fsb. my vcore is set at 1.3 and I can't adjust it through bios, while the fsb:ram ratio stands at 3:5. the motherboard doesn't seem to overclock much, except possibly due to unstable ram.
