x25-m slow read help

[idata]

I have a really weird one here that nobody on other forums has been able to help with.

I have an Intel X25-m SSD. It's on a gigabyte ga-p55a-ud3 using a core i7-860.

I have a maximum read speed of 182mbs using HD tune. I've been through the pio

thing and have since moved the SSD to channel 4 and it's udma-6. No change in

speed.

Here's comes the part nobody can figure out. If I overclock the processor using

either Gigabyte's Smart 6 utlility or manually overclock it, I will suddenly get much

higher read speeds of 235mbs.

If you have any thoughts on why this is, let me know. I'd prefer to run my 860 at

reference speeds for longevity.

is the SSD connected to the white or blue ports on your motherboard?

which port exactly, as they actually have designators like SATA2_0, SATA2_1 etc

are you running XP?

PS. I have sent you a private message; I need your help too if you have a spare moment!

My SSD was plugged in to the O port at first and it was going to pio 4 mode.

I switched to port 4 and now it reads ultra-dma 6 but speeds are still low unless

I overclock.

It's running windows 7 64 bit.

Okay, where are you determining PIO/UDMA modes from? From HDTune by chance?

Secondly, are you using your Intel SATA controller in AHCI or IDE mode? it sounds like IDE from the above, unless you are using HDtune as mentioned.

No, I check the mode through device manager.

ACHI is enabled.
