Maximum Reference clock HTT?

post #1 of 9
Thread Starter 
I can reach 260MHz on my msi 990fxa gd80vs, after that it fails. I have been lowering my cpu/northbridge/ht link/ram to try to keep them in normal limits.

I have tried a couple combinations like 270, 280, 300. But nothing works, am I missing something?

Unfortunately theres a limit to how much you can raise your reference by. My limit is around 280.

If you want to get huge overclocks by using the reference clock alone, you should pick up a ASUS Sabertooth or Crosshair. From what I heard they can go up to 300.

ya that sucks i have to run my ram in 1333 because higher multipliers mess's up my available memory in windows. i can run it in 1866 only if my north bridge is at 2000. :/

Can you explain how higher mutis mess up your memory?

The RAM muti, the CPU muti or the HT muti?

2000 HT is the default for 6 core Bulldozers / Visheras I think.

The HT link and the CPU do not effect it, but if I have my Memory set on the 1600 or 1866 multiplier, and I iether increase the HTT or the north bridge multiplier, It will boot fine but windows will only show 4GB of memory available, as opposesd to the 8 it says is installed. resource monitor shows the 4GB in hardware reserved.

If you want to run 2600 HT then you might need 1.26V or more.

1.2V is good enough for 2000 HT.

ok ill keep that in mind. i turned down the ht link to 2000 and it might have worked at least i think i have some more options. i played with it a bit and it was working but the settings im aiming for are still giving me 4GB so i might need to do some more experimenting.

edit

thanks for the tip man, some how my bios liked to keep my th link at 2600, and 1.092v switching it to what you said definetly opened up more possibilitied...and it put that seed in my brain.

the seed that said "set the ram/NB to whatever u want, then turn the latencies back to auto, and walla i got my 8GB at 9-13-13-37 smile.gif im a play with those later to see what i can squeeze out of it.
