slot 1 and 3 the correct slots

stock HT Link speeds are 2600, which puts your CPU/NB and HT Link (now underclocked 400 Mhz) even. i have seen others be okay with this, but my 6100 had big stability problems in this configuration on my Sabertooth. have you tried getting the HT Link speed back up?

also, have you tried anything with the LLC setting in the BIOS? went a long way to providing stabilization for me.....

no i think they are on auto unsure what to set em to so havent played with em also on my asus crosshair not sure where LLC is

Additional Comment:

well i know im probably at max till i get a water setup, as these fx also double as a portable heater when you overclock em

[moosteve]

i guess i am not sure but just assumed it had LLc as my Sabertooth does. it is in the Digi vrm section.
and i hear yah... i had already gotten liquid in place when i went to the FX so i am glad i didn't have to go through the struggles on air. i also added a small Antec spot fan to blow across the VRM heatsink as they were getting pretty toasty.

I don't recall HT being that fast Moo. That would mean the NB is running the equivalent speed or faster. I also recall some one saying that it was hard to clock the NB/HT beyond a certain point with these FX chips.

Here's the settings from the First 4100 I OC'ed. 2.7ghz NB/HT multi of 12x. This will include voltages that I used as well. http://forums.extremeoverclocking.co...8&postcount=13

my FX6100 defaults to an HT of 2600 and an NB of 2000 under default settings. what i have read about overclocking the 8xxx series is that it defaults to HT 2600/NB 2200 under default settings, but i have not had one in my own hands.
there was some confusion when Bulldozer was first released because this was the first AMD cpu where the HT value was higher than the NB value. that being said, i have seen some able to overclock the NB higher than the HT, but i cannot, and a higher NB seems to be of little value, at least in my bench results.
i run my HT just over 2600, and my NB 2200+ daily, as this seems to be the best for stability with high cpu clocks, in my experience.
i believe cecil touched some on HT/NB in his bulldozer thread(s), but i don't have the time to look at the moment.

Who? Howz bout' you just slap a Recent screeny up here of HT being higher than NB. I don't think the board would post. In other words I think cpu-z may have been wrong....

from my original overclock thread. up to date {at the time} aida... BIOS says the same.

here's what the most up-to-date version of cpuz says just for laughs...

bios shot.......

.... and my current overclock....

i use the Aida because the version of CPUZ that works correctly with FX chips does not read the HT Link speed... and neither does the online validation.

[ShrimpBrime]

Yea all the readouts are incorrect. (cpu-z) I am still doubting an HT speed past that of the NB.

And you have a 13x HT multi right? That's not on auto is it?

[ShrimpBrime]

So I gave this a shot on my Phenom II. Considering the Cpu has nothing to do with the NB and HT being linked to it.

I manually set via bios a 2200mhz HT speed. THe board posted fine and defaulted to the NB speed of 1800.

Pretty sure your being fooled by software. I've never ever seen HT go beyond NB on any AMD. Not that it would matter, cause the NB is where the improvements come from anyways through sheer bandwidth.

Here's my SS. Bios posted HT 2200 and NB 1800.... But I don't have it....

[ShrimpBrime]

• HyperTransport™ Technology
• HyperTransport™ 3 technology supported
• Maximum one (1) link on AM3r2 package, 16-bits in each direction, supporting up to 5200 MT/s (10.4
GB/s) in each direction in HyperTransport Generation 3.0 mode

HT 3.1 is 6400 or 3.2ghz HT speeds or Up To 3.2ghz.

HT 3.0 is 5200 or 2.6ghz. We know this from Phenom II.

Even if your running 2.6ghz HT with your FX Steve, it's still way underclocked.....

bulldozer and PhenomII are not the same and do not overclock the same.

there are no multis in this BIOS, just frequncies. but i do choose to believe the BIOS read-out for clock speeds, and the countless other threads which state these are the stock speeds. yes it is on auto, optimal defaults, which is stock settings for this boad/cpu combo.

i stated that that stock HT speed for the FX is 2600. i didn't say it was or wasn't underclocked. there is difficulty in overclocking both the HT and NB as compared to phenoms. for example, anything over 2350-2400 on the NB will cause major instabilities (app crashes, lock-ups, etc) and overclocking the NB saw little benchable improvements . i have seen others overclock both with much greater success, and i brought up Cecil the other day because i think he kept his 2 even, but my set up will not do that. i am not even sure if the NB can be clocked past the HT.

included is a screen shot, from this morning, with defaults loaded in the bios and just the HT and NB hard set. if you still don't believe me, come on over this weekend and play with it for yourself.... i'll buy good beer and bbq some ribs.

[ShrimpBrime]

This is because a 9 series chipset is the same as a 7 series chipset. HT 3.0 speeds.

Your board is likely defaulting to the NB speed, there's just no way for me to prove it cause your readouts in windows aren't working.

My board says it's running 2200 but in windows defaults to the NB speed.

I'm tellin you, HT can't pass the speed of which the NB is running.

You'd be the first case of this that I am aware of if it where true.

Everything I googled and wasted time on shows me that HT can't pass NB.

Not sure what your getting when googling....

Your right. Phenom II is way better for overclocking. The NB speeds can easily hit 3ghz. HT runs NP at 2.6ghz.

The Bulldozer, which I've had a few of now, are garbage. Sorry if you think otherwise, but my Phenom II clobbers my FX chips period.

I'd come over just for the ribs and beer I'll bring the kids to destroy your stuff and game your PC to death like they do here at home.

Additional Comment:

The NB and HT are related, and in fact, you can't set the NB speed any higher than the HT speed. Overclocking the HT speed has been shown to provide only marginal improvements in performance (perhaps in cases when multiple high end GPU's are being used)

Taken from http://www.overclock.net/t/525113/ph...clocking-guide

and pretty much any guide that's better than mine, cause I don't recall mentioning the ht being the same speed or lower than the NB and I'm too lazy to look atm...

It's been this day since day one.

My 939 Opty 146 is running currently 1080mhz and the NF4 chipset is likely running the exact same speed. Haven't needed an ov on this one yet, but I'm still playing with it.

And totally no offence to you at all MooSteve. I just think the readouts are wrong. Some software will readout what bios was imput'ed But the real time reading will differ. Perhaps try using your fav AOD program ?? Dunno... pretty baffled why your system is running a faster HT than NB speed.....

[moosteve]

My thuban clobbered my fx as well. I never said the fx was better just different.
What I am looking at are other people overclocking bulldozer most with a higher ht than nb.
All I know is I cannot clock the nb higher than the ht and I don't know how I cannot believe what my bios is telling me if I actually hard set the frequencies. That makes no sense. You are telling me to ignore my bios... So i guess that means cpu frequency might be wrong?
And no offense taken. This is just all I know and it has been talked about since bulldozer was released.

[ShrimpBrime]

A quick test would be to set the HT to a beyond normal freq. without v increase for compensation. So an HT setting of 3600mhz effective would be out of the ball park and shouldn't post. I do not intend for you to hurt any hardware trying, but IF Shrimp where correct, your reading will be that set by bios and have a running system where in reality would not be possible.

The board should default HT to the NB speed whether it displays it correctly or not. At this point you can rely on the NB readout for HT speeds considering HT shouldn't be able to pass the NB.

If your running 2.6ghz, that is running HT 3.0 speeds any how and 3.2ghz should be achievable IMO. But I know that these chips are rare to see 2.8ghz NB/HT clocks, where the Phenom II can push past that on the same cooling device.

Ok. Will try when I get home tonight. Thanks shrimp.

just so you know i am not avoiding... got a few things to deal with here....

where i am at....
latest BIOS, under default settings, 2600 is the highest HT speed in the list....3200 for the NB.
to achieve a higher HT speed i have to raise the FSB.

took FSB to 300(a known stable FSB on my board), reset cpu and NB to as close to stock as i could, hardset HT, dram, NB, and cpu voltage to stock V to make sure the board would not overvolt or raise voltage for tests.
the HT seems somewhat ok up to 3300, though it will hang on restarts beginning at 3100... i ran a little Prime... not sure if in stability in the HT will show up with that kind of tests.... would not boot at 3600.

gotta work now so more later

[ShrimpBrime]

You also fight stability with your Ram using the FSB. So we can't say the HT is making it unstable.

Knowing your HT maxed in bios at 2600mhz is enough to know that the 3.2ghz HT speed without voltage increase probably isn't real.

Really need to look at other monitoring programs and see if we can't get a live readout. IE: Gpu-z will read clocks set on main tab and then the sensors tab will read actual speed.

[moosteve]

Aida is real time. The newest AOD is giving the same readings.

My ram well underclocked with loose timings and hardset voltage. So I am not fighting the ram. Give me some credit for knowing something.

AMD tech support is telling me it is 2600 so far... I'll let you know more when I know more.

[ShrimpBrime]

Plenty of credit. You earn it for yourself IE hitting 3200mhz effective HT clocks.
