Intel X38 Tango - Is High FSB Overclocking Worth It?

E6850 and VMCH/FSB/tRD do the Disco

We ran a series of quick stability tests using OCCT. Although OCCT will pass at a speed of 6X548 FSB with as little as 1.41VMCH, stepping up to the 7x multiplier requires a significant increase in MCH voltage. Interestingly enough, backing off a mere 4MHz on the FSB (to 544MHz) brings the MCH voltage down to 1.54V.
Using anything beyond 544 FSB requires an absolute brute force approach to get the board stable enough to generate more than a few screenshots. Lower multiplier locked CPUs will naturally need these higher FSB speeds to acquire high processor overclocks to match CPUs with higher or unlocked multipliers.
This is assuming the processor itself is capable of running high FSB speeds, and finding those is about as tough as doing the foxtrot with a Sumo wrestler. Let's move over to the E8500 and see what happens to the achievable FSB rates. We will also compare performance points between multipliers and FSB speeds.

I really enjoyed it and look forward to another one with Quad Cores if possible. Loved disco Stu and based on the dancing comments it seems as if Gary's humor has rubbed off on you.One thing, is it possible to show a few more applications in the next article, gaming is fine, but would like to see what happens with encoding and Maya/Photoshop when overclocking a system. I barely can get above 400FSB with a Q6600 at 8x and hold steady on a Intel X38 board.

Hi,We can take a look at Quad VMCH next up. Along with some different software too...

A great article - it truely shows how to overclock intelligently - it's based on facts/evidences, not blindly increase the whatever voltage and see what can be achieved. Congrat!!Owls - Tuesday, February 26, 2008 - link
and very informative. thanks!Sylvanas - Tuesday, February 26, 2008 - link
haha nice use of all the dance references, made my day.Great article, I enjoy these articles explaining more about Trd and various other BIOS settings, goes to show intelligent overclocking > max voltage/fsb stupidity.
