Loooooove it! (Yes made the switch to AMD for now.)



Asus Crosshair IV, 8GB Corsair DDR3-1333, GTX470, Corsair 750w.

286x14
1.2NB volts
1.525 cpu v-core Works under load at 50C, 12 hour 100% cpu stressed test, then 5 hours of BFBC2, Mafia 2 couple of hours, Metro 2033 maybe hour game is boring to me. I tried turning down the Vcore but it bsod'd after running great all day yesterday and this morning. So, its idle around 22-24C, 48-50C load on a push/pull H50. I have mine pushing air out of the case, but have a 120mm fan directly above the intake fan on the H50 pulling air in from the top, directly to the H50.

I would like to push the memory to its rated speed, but that also leads for a high fsb but the only option at the above setting is 1525mhz on the memory which is above its limit I believe. I'll try it, but I really like being stable right now. :p



Don't care about 24-48hr testing. Its running everything I do perfect. Can't wait to convert Disney HD Vacation videos over to Blu-Ray. (720p@60fps, 1080p for a few)

What is a good software program to get for doing these video transfers to Blu-Ray?(Something that will utilize this cpu.) Thanks.
 
Well, tried going higher on the ram, won't do even with higher voltage. Tried upping cpu vcore. No go. Need DDR3-1600 to get high fsb. This will do for now though. ;)
 
Some anecdotal advice from experience, in a P182 with a new 6870 CF setup and an H50. Having that fan setup is good for CPU temps but will turn the rest of your case into an oven. The H50 isn't enough to exhaust all the air out of the case. I had my cards in the 85-95c range and my HDD's in the bottom section above 50C. Changing the top fan to an exhaust solved this at the expense of higher CPU temps. YMMV with a single GTX 470 though.

1.525 seems high for an X6 at 4? Have you tried lower volts? What is CPU-NB at? LLC on?

I was gonna say something about that too. It's not special that you reached 4ghz on the first try if the first thing you do is pump a shitload of voltage into it. Though 4ghz is still 4ghz I suppose.

its high but still within the max voltage limit along with the temps being 12C below max I'd say hes fine with what its set at. also depends on if its the 95w or 125w version.


i know you dont want to do 24 hour stress testing snowbeast but I'd suggest doing 10 passes on IBT that will at least tell you that its completely stable. should take about 45 minutes to an hour to do. the biggest reason I'm suggesting you run this is that you plan to encode movies. if the processor isn't completely stable you will see glitches in your encodes.

also another thing, do you have your CPU-NB overclocked? that will make up a huge difference for the fact that the ram isn't at reference clock, should give you a nice boost with the encodes as well(depending on what encoding software you are using).

Just wondering, why would it matter if its the 125w or 95w version?

Except for the slight possibility of it being binned higher, the only difference between the 95w and 125w are the bootup and turbo VIDs which no longer matter once you manually control the voltage.

People are hitting 4ghz at 1.4v-1.45v so it just seems unnecessary to pump that much voltage into it from the start.

I have two Scythe Flex fans at 2000rpm on the H50. Scythe Flex on that top inlet. Next to it is another in push out. On the door is a Scythe 3000rpm 140mm pushing in. Front on drives is another Scythe blowing over them. Bottom pushing up is a Thermaltake 120mm. All hooked into a fan bus controller.

By all means this probably shouldn't work, but it does. I am making a divider for compartment like airflow to keep it like the diagram.(If thats what you wanna call that sad picture. :D )



Been throwing everything I can at it and it has been fine all night no hiccups what so ever. I am happy finally, thats all that matters to me.

NB volts are at 1.2v. Oh and my HDD's have never gone over 35C that I can remember. Thats really the one area definitely make sure there is proper air flow.

Good night. Its been fun. Finally, finally I am happy.....:D

because like you said they are higher binned chips. other thing is most boards are set to use the incorrect voltages. for example most boards set the 1090T to either 1.325v, 1.35v or 1.45v well the stock voltage for that processor is actually 1.27-1.28v. its the same thing with the 95w 1055T's the voltages are incorrect they should be 1.25v which typically means that you have more headroom on overclocking and on top of that means you can usually hit the same clocks at a lower voltage. also the early 1055T/1090T's required a crap load of voltage where as the newer batches require much less voltage to overclock.

but to your real question. yes theres technically nothing different between the 95w and 125w processors. both will run in the mid 1.2x voltage range which gives you a 95w processor.

as long as he stays under the max voltage and max temp on the processor there really is nothing wrong with putting that much voltage through the processor, yes he will be consuming more power then he should be, yes he will put more strain on the mosfets but that boards designed to handle way more voltage and power output then he's doing so it should be fine. now if he was running F@H 24/7, i'd definitely tell him to try lowering the voltage but seeing as how that processor will sit idle the majority of the time i don't think it will be a big deal.

my guess for his high voltage is that hes running the CPU-NB overclocked and is compensating stability by overvolting the processor instead of increasing the voltage on the CPU-NB. but thats just a guess.
 
In simple words.... Grats you have one fast 6 core and im sure video encoding is going to haul arse for ya!

Oh we get that it is within the safe range of voltages, but it seems he just set it high without adjusting, since he did say 4GHz first try.

While it's safe he could easily damage something that prevents him from hitting those clocks again. I would try starting at 1.4 and go up from there.

completely understand that.. though in my opinion i'd try pushing the overclock higher since he's definitely got the room with the high voltage i would guess he could hit 4.1-4.2Ghz with a little tweaking at that same cpu voltage.

but being that it is an AMD chipset motherboard he could use AOD to test lower voltages by running IBT and slowly lowering the voltage after each pass until it fails. then going back into the bios and setting it 1 notch higher then doing 10 passes of IBT to see if it passes. thats usually what i do. hell i'm sure ASUS probably has overclocking software that does the same thing.

I got into Windows once at 4.2 on my 1055T, but now I can't remember how I did it. Been stuck at 3.5 for the longest time now.

Here it is: http://valid.canardpc.com/show_oc.php?id=1441306

Wish I could figure out how I did it :(

Drop your HT Link multiplier to 7x (1400 MHz) again. Drop the CPU-NB to 8x and raise the CPU-NB voltage a bit. You can try the 9x (or 10x;)) multiplier and more voltage later after you get the core dialed in. 4.2 GHz isn't easy on a 1055T though. In fact the fastest stable 24/7 air-cooled 1055T I see in the XS charts is only at 4,050 MHz. My 1090T can't even do 4.2 GHz at reasonable voltage. What you likely saw was barely stable enough to boot and validate.

depends on what batch his 1055T is from, the first couple batches were shitty overclockers and power hungry, and the recent batches have overclocked very nicely. along with the 1090T's. for example wfeather's 1090T is one of the early batches that max's out at a little over 4Ghz i believe. where as another member here(ccityinstaller) his 1055T did 4.3Ghz but was from a newer batch. the early processors were hit and miss but most of the later ones are pretty much binned perfectly working 1090T's due to the high yields on the x6's.

but i agree on your settings. most people forget about the HTT(hypertransport) clock when overclocking the locked processors. the one problem a lot of the 1055T's have is the NB being overclocked when trying to exceed 4Ghz. some can handle the 3Ghz overclock and same absolutely hate being overclocked. so its a lot of trial and error.

Yeah I don't care about 4.2... I just want ~4 back. I can't get it to boot above 3.5 right atm. I'll try your suggestion.

It's one of the 95w versions. So, I assume it'd be a later batch.
