Is there any way to stabilize an HTT overclock?

[reflex]

Hi all,

I was just wondering if there is any voltage or something I can set to stabilize my HTT overclock.

My previous MSI 890FXA-GD70 would boot windows on 325MHz, with no adjustments to voltage, however since they changed my board it seems anything above 290MHz or so won't make it to windows.
Anything above 305MHz hangs on "Initialising USB controllers".

I am currently running 285MHz and that is stable.

Thanks in advance for any advice!

System Specs:

MSI 890FXA-GD70 Bios 1.6
AMD Phenom II X6 1055T
4GB Samsung 1333MHz el cheapo RAM
MSI 8800GT OC 512Mb
Corsair TX650W
WD 1TB SATA3 Black 7200rpm
Seagate 1TB SATA II 7200rpm
Corsair H50
CM Storm case

Can you make a CPUZ screen?
do you have to be low HT multi?

[reflex]

I don't have a screen shot at the moment.

Basically I have set all the ratios so that everything is running at approximately at stock speed other than the HTT.
This was in an effort to try find what my max HTT is.

[reflex]

Should I raise the NB and SB voltages?

[crazydiamond]

might not hurt. try with nb & sb around 1.2v, htt around 1.26v... idk what else they have in there but just start messing around just remember what you changed etc. see if any of them let you get more htt.

[reflex]

I don't seem to have any voltages that are specifically for the HTT

My voltage setting in the bios look like this:



These are not the voltages that I am using, it is just to show what I can set.

I increased HT Link and NB voltages up .05v and i've managed to hit 350+ htref.

Hope that helps!

[reflex]

Will give that a shot this evening.
Thanks

[reflex]

Ok, so I tried increasing HTlink, NB and SB voltages a bit.
I received BSODs while booting windows on 300HTref.
I think I had
NB @ 1.25V
SB @ 1.19V
HTlink was a couple of steps up from auto, cant remember exactly what is was.

I'm not sure what are the safe ranges for these voltage so I don't really want to push it until I know that.

Dont forget when overclocking via HTT,your ram will come into play.

[reflex]

I assume lowering the ram multiplier wont make a difference?
Will adding more dram voltage help?
Thanks!

[CoNtAcT]

when you have 300+ htt you must low the dram multi

[reflex]

I have always lowered it, so that the memory is running below 1333MHz. That didn't make a difference.
Maybe a little more dram voltage will solve the problem, I shall try this evening.

[CoNtAcT]

try this, but the different from DDR3 ram an CPU NB VCore must be not more than 0.5 V

Make shure your Using the Same Bios as Old Mobo or the newest available to ya.


Dont push the HTT while pushing NB freqency ..Well untill you figure whats going on..

I crank up the HTT with close to stock Nb and Ram timing..Only pushing the CPU Cores with HTT and close to stock NB/Ram ... then i tweak every thing else up to par once the highest HTT is reached with Max CPU clocks.

Sometimes a little more than stock Nbvid volts(CPUNB) helps the Ram(IMC) using More Chipset(NB and SB) Helps with Video cards to not BSOD's. Further more it helps Hyper Transit stability.

A few Clicks above stock usually is all thats needed .. This goes for just about any mobo and any CPU(IMC) you may be tweaking.

Make shure ( Ram Drive strengths )are set correct ..
If its set too tight you wont be able to tweak above 300htt as easy.

Last,,
Remeber two Mobos are Never the Same ....
Be shure about the other hardware,,Ram ,,Drives,,Video cards ,,sound card excetra ,,down to even the Number of which Sata ports you used for the HD's. Some Mobos Sata 5/6 get fubared when over clocking..Most manuals will say which ones to use when Overclcoking.

* Running Sata HD's can create a small Problem ,,
once the HTT goes above a special limit , lets say (*300htt) you can lose drives( Mobo drops the Sata Ports I/O's and USB's and or Lan port)

You will usually get a BSOD at this point or lose data and have to reinstall windows . Usually you can run a add in Sata Card or use good old IDE's to remidy that too ..Ive seen plenty of drives get wiped out from using High HTT

Hmm Did you set teh PCi-E/PCI clock @ 100 (Even if Default is Auto) If not manualy setting this limit your HTT on some mobos may not be locking the PCi-E. this will give a nice BSOD once the Higher HTT limit is reached too.

Just dont do what ever it was returned for

[reflex]

Thanks for all the advice.
Just to check, what are RAM drive strengths?
I'm quite sure the PCI-E clock is locked @ 100.
I will check out the SATA ports thing tonight.

Yeah I returned my other board, but now that I think about it, it was probably fine and was just the CPUs IMC...
Anyway I don't think my supplier checked it properly and just swopped the board

[reflex]

So it looks like about 290MHz is about my max. I tried setting memory voltage a bit higher and that didn't seem to help either.
Its not the end of the world, 286 is enough for 4GHz. I was just interested to see how high this CPU could go coz it seems like a good one

[Daveburt714]

I'm working on HT clocks too reflex....

If I find any new tips that might help I'll be sure to let ya know.

GV, gave you some really good advice make sure you try his suggestions...

If you think you've found the limit, play with "Turbo Core", it can offer some really nice benefits
on single threaded apps, and it comes in handy for the 1055's...

[reflex]

Thanks for the advice everyone.
I haven't had much time recently to fiddle around, but I will be sure to try out all these things this weekend.

I had a bit of a weird occurrence 2 days ago or so, I plugged a joystick into my USB card reader and the PC sort of went into a standby mode (Screen off, everything else still spinning and running)
It required a hard reboot to recover from this... From what I could tell there was no hdd activity and CPU temp was @ about idle looking at the display on the mobo

I have tried to reproduce this scenario but with no luck, it may be that this USB port on the card reader is a bit funny and shorted or something when I plugged the joystick in..
Anyway, that was at 286 HTref.
I don't think it is the mobo dropping USB ports as I have had many other things plugged in and working, including external hdds and flash disks.
