HT multiplyer? RAM divider?

death_looms · 6 Oct 2007 at 19:05

I'm quite new to overclocking, and I've read that to find the max stable FSB you should lower the cpu & HT multiplyer (athlon 64x2 4600+), and also the RAM divider. I own a Sapphire PURE Innovation PI-A9RX480 Motherboard, and can't seem to find there settings anywhere! (I tried flashing the most recent BIOS, but it failed, back on the old version now: Pheonix Technologies, LTD 6.00 26/09/05 and SMBIOS(?): 2.3.

Could anyone tell me where these are, or any other names they go under?

Appreciate it!

Memclock Index Value is the memory divider (200mhz is 1:1).

And LDT Bus Frequency is the HT multiplier, tho since it's an ATi chipset it's not an actual multiplier, and I'm not quite sure it it's necessary to change it as I believe the HT isn't linked to the FSB (if you set 800mhz it stays at 800mhz).

I'm not sure, I think that it did increase, but ill check that out when I next get on my rig and let you know. cheers

Just had a wee nosey there, found the Memclock index value!

However, I still cant find anything to do with the HT multiplyer, the only thing that seems anywhere near it is the HT PLL or something. And when I upped the FSB from 200 to 210, the HT reading in cpuz went from 1004MHz to 1053MHz.

Might try the BIOS again, see if it works and gives me anything new.

The LDT Bus Frequency option is in Advanced Chipset>LDT and PCI Bus control.

Cool, I'll have a look now! Thanks

FOUND IT! Can now increase the FSB and keep the HT/memory under stock as well as the cpu! Thanks for the help Cob, time to see how high this'll go.
