"Performance Enhance" in Gigabyte mobo BIOS ...

[NoobyDoo]

Just went thru "Overclocking Intel's New 45nm QX9650: The Rules Have Changed" at AT.

And tried to go thru "ASUS ROG Rampage Formula: Why we were wrong about the Intel X48".

Just understood ( sort of ) what tRD is/does.

The option MB Intelligent Tweaker -> Performance Enhance in the Gigabyte P35-DS3L, does it do anything else besides change Static Read Control Delay (tRD) values ?

Yes, it obviously does. When I first got my GA-P35C-DS3R, it was set on the default value of Turbo, and it had my Crucial Ballistix running with a tRCD of 0. Since I knew that my RAM had an SPD tRCD of 15, I tried changing it to 15, while leaving it set to Turbo, and it either wouldn't POST, or was extremely unstable.

I don't get it. He said Trd, you said Trcd. They aren't the same thing.

Essentially the Enhance mode changes Performance Level (in MemSet 3.4) to 8 from 12. After having changed the timings from:

tCL - RAS = CAS (Read/Write) - tRP - tRAS from 5-5-5-14 to 5-4-4-15 with mobo set to Enhanced from Standard my 32M superPi score decreased from 17 min 43 seconds to 15 min 49 seconds and WinRAR score increased from 1649kb/sec to 1774kb/sec.

I think the Enhance setting tightens the internal timings of the northbridge chipset.

"Performance Level" in MemSet is the tRD value.

This is what the Gigabyte manual says :

Performance Enhance
Allows the system to operate at three different performance levels.
- Standard Lets the system operate at its basic performance level.
- Turbo Lets the system operate at its good performance level. (Default)
- Extreme Lets the system operate at its best performance level.

1) If Standard sets tRD to 12, and Turbo sets it to 8, what does Extreme set it to ?

2) Are these values ( 12/8/? ) fixed, or do these values change with FSB ? Or with the CPU default FSB ( and therefore the default strap ) ?

Think Gigabyte customer service will respond if I ask them ? I'll try ...

Anyone knows about the Asus P5K-E boards with the equivalent setting called Transactional booster?

I can't seem to set anything greater than enhance level one even after following the FSB, staps, etc settings on Anandtech's X48 article.
Are those settings applicable to X48 only not P35?

The Gigabyte boards (atleast the GA-P35-DS3) have the ability to set tRD separately in BIOS. The setting is called "Static tRead Value" and it only affects the "Performance Level" as reported by MemSet 3.4. It has a pretty large effect on memory performance too.
