no. but will try that when i get home from work!
woot. lost alot memory performance changing those 3 things...
From 6k to 5k in read and from 2,5k to 2k i write. latency went up alot too
Edit: didnt help me oc. still bsod while booting @ 305htt
Guess ill still need to raise voltage to NB to get higher, and i dont feel too comfortable with that without better cooling as the nb sink was pretty warm @ stock speed (50+?)
edit: never mind the first statement. just me remembering wrong. its actually opposite:)
ok.
What is mps rev 1.1?
and what is ddr drive strenght (n) and (p) theyre set at level 6 both of them
Btw. i can restart without problems, but i cant turn of the system and turn it on again. have to clear cmos for that.
You need to adjust Max async latency and Read preamble. These have very different settings from the DFI nf4. Try 9 and 7 respectively.
You don't need better nb cooling, or much voltage :)
Edit: My NB voltage is at 1,3V and I'm running ~320 HTT
tried stock voltage, 305 no go. tried 1.3 305 ok, tried 310 no go....
will try those settings. is that for higher ram or higher htt or just performance?
Daam my nec nd3550 refuses to work on this motherboard and that is a big no no
edit:those setting lower performance a tad, so i guess its for higher ram..
Try upping the HTT now. I'm running 133 divider and ~200 MHz on ram.
ah! nice one. 305 stock voltage worked now!
Edit: not very stable though!
tried upping some volts here and there, and adding a small fan to the NB sink.
seemed stable @ 305 but 310 was still no go.
back to 300 for now...
did you give your cpu a little more voltage? It should do 311 @ 1.39v no problems. Also did you lower your HT multi to 4. @ 5 you will be over 1500. It is doable but you will need to raise NB volts more and there is no gain to be had with it that high.Quote:

Did you manually set ram volts or let it auto?
What is it set at?
Edit: Also dram drive strength to normal and dram data drive strength to 50% reduced, as it looks like your chips are Infineons like mine.
2,7 but tried 2,76 just to be shure...
Any chance of a A64info shot so we can see your timings. It must be a simple oversight as people have done in excess of 400 HTT on this board.

here.
Edit: oh it was a64info you asked for... downloaded it, but tweaker show the same info so i guess its ok?
ok figured it had to do with something i did, so changed back to default only changing waht you told me earlier.
Writing this @ 310htt....
tref aint right though, its 7,8 in bios...
tref in windows never matches tref in bios ????? :( A64info seems to read it properly though.
I do find my machine more stable when my tref matches my memclock. You could try 133Mhz 3.9us or similar for tref.
Your timings a relativly loose for your ram so once you get your CPU where you like it you can tighten them up a bit.
Sounds like you may be getting somewhere. :)
You guys can leave the NB voltage at default for anywhere around 300 HTT. It will do that very easily at default voltage. If you raise the voltage all you'll succeed in doing is burning more power and creating heat in your case. :nono: In terms of raw HTT, the chipset is good to atleast 350 at default voltage. After that, with a 0.1V bump it'll do in excess of 420 HTT. The reason why few people ever suceed in doing this is that you need to change some memory timing parameters at around ~350+ HTT to make the board run stable and it has nothing to do with the chipset it's a CPU thing. Check the async latency ;)
315htt now. gonna leave it there while i sleep. lets se if F@H fails....
Edit: oh, so 1,22 is ok to around 350. guess ill never get that high with my cpu, but nice to know!
What are you using to check tRef in windows? If you are using the tweaker, it's wrong.

1560 is 200 7.8us but, i agree it is always what you have set in bios no matter what any proggy might say.Quote:

system har been running half a day @ 315. 1 core kept sending in unfinnished wu`s (F@H) but im confident that it was just a little low cpu voltage (1.375) for the speed (2835) so upped it to 1.4. will wait a few hours to se if its ok, the try 320++
Ok getting more satisfied with this mb now. but 1 major drawback. that my nec nd3550 doesnt work on this board. anyone have an idea about that?
What's wrong with the nec drive? Is it a master or slave? Any other devices on the same IDE channel?
