AMD users how high can you get your HT speed

[regan1985]

i read somewhere that going above the max ht doesnt result is any gain in performance?

Here is my Super PI score which corresponds to the 3rd pic above:

sweet, fastest i could go was 29ish seconds on my Opty 170, better stepping? or i'm just a bad overclocker...

ht speed increase does benfit but its only marginally

 

[cdawall]

its similar to oc'ing your pci-e bus

hmmm...i like this thread....and take it as a personal challenge. Ima go AS high as i can
I currently run it at 1230MHz....but ima go to like 320+ FSB with a 5x multi....ill be back

 

[p_o_s_pc]

so ur trying for my HT OC

 

[erocker]

I am trying to beat it now.

 

[Urbklr]

I got 1565MHz.....but some parts in my comp are holding me back....*cough*shit corsair ram*cough*....or maybe its my mobo being all wierd and not letting me raise my FSB without raising my ram voltage(have to use 2.25 for 315MHz....stupid mobo) and i HAVE to use ram at 533MHz...or no boot.

Mitsirfishi- What settings do you use on your board to get high FSB's?? Im using 902 bios too...maybe thats it...but are you having similar problems??(probaly not becuase my mobo hates me)

Later ill try for more.

1600... Oh Yeah!!
I think I can go further.... If I need to.

 

[p_o_s_pc]

i got 1650 but i couldn't get a SS because the screen was starting to turn black and turning back to the desktop than it hang.

amd users how fast can you blow up your motherboard?

 

[p_o_s_pc]

IDK why don't you send me the money for a new one and i will find out.

This is the highest I've bothered to set my HT to because I never really thought the gains from setting it higher outweighed the added stress it put on the system. That score result was done on an extremely untweaked and unoptomized system FYI and I still have more headroom but I decided to call it quits for the night. The screenshot was originaly done for Wile back in another thread that I started earlier so please ignore the Super Pi result to the left.

It's socket 939. I think it's getting about that time. Just waiting for Phenom to buy my next rig.

I win! For now...

 

[curt]

um yeah lol

i know the ht is low but that opty 165 rules

i burnt a board doing the 356fsb lol an the cpu could do more

 

[p_o_s_pc]

if you can burn a board than i better stop till i get closer to getting a SLI chip-set.

 

[p_o_s_pc]

for now... Maybe i should have taken a SS when i was around 1620 +/- a few. when it was still stable.

well i was using the 0804 bios ive found that is the best bios like a wood burning stove
but i did get the north and southbridge actively cooled with 40mm fans it made a slight difference and let me overclock an extra 5fsb lol but it also let me get 1620htt on a suiside run its the chipset what cant take it 3ghz of htt is quick enough and that is what they are going to pump the next gen of amd's im sure

Wow, that 165 IS awesome!!!

*Oh, water cooled.

 

[curt]

woot

ok i have a dfi expert board on the way im drouleing allready lol sead by many to hit 440fsb an higher ohhhhh yeah

soo in a week or so ill be poasting what my opty 165 can rilly do with my water cooler

3.2gh so far an killed the asus board [3.2gh 1.400v core temp of 38c water 23c]

then i might evin seal the board an try -25c coolint temps agean with my ac/chiller unit

oh the fun i could have lol

I found that as soon as I overclocked my memory over 350MHz the HT would never be stable over 1000MHz without lots of voltage. For the purpose of this thread I upped my HT to as high as it can currently go 1033MHz. I normally run it @ 775. Quite oddly my SuperPi benches became 2 seconds slower with the higher HT speed. With 775 I got 31 seconds, with 1033 I got 33.5secs.

 

[mitsirfishi]

I win! For now...

you win for nvidia user im just ahead for ati user

Wow, I guess you folks were right! Although somewhat small, the HT speed does have an impact on performance. I went ahead and tinkered around with my HT link speed tonight as I was fairly bored out of my mind and increased it by a small margin. I noticed a small gain in SuperPi 1M scores with the new (and higher) HT link speed!

As you can see, I've gained nearly 0.6s in a 1M test run with the higher HT speed and with a slightly lower clock speed as well! FYI, 2.8GHz is what I run my system @ stock aka everyday use. Actual stock speed of my Opteron 1216 is 2.4GHz.

Original run @ 2.825GHz speed, HT Link @ 942MHz =

New run @ 2.800GHz speed, HT Link @ 1.165GHz =

I think I'm going to try a new batch of 1M runs with the higher HT speed now and see how that pans out.

well i wouldnt of bothered saying anything if there wasnt any improvement but keep pushing till your board falls over
