with memory still at 1600mhz cpu 4000mhz and nb at 2800nb 1.25v i am fully stable, now if i raise cpu to 4.2ghz sometimes 2.8ghz on nb i stable sometimes its not, has to be bug with the board with core unlocker
Be Lucky, youre at the Edge of the Procs performance, you probably have one of the most golden unlocked chips on this Forums, of a kind that i only have seen CDAwall posting long ago... it isnt your board, its simply the end of it, the proc cant do more. (if you dont plan to go phase change, or chilled water
)
Over 1.4v. I've run mine at 1.4v and currently 1.25v and it's been perfectly stable for months.
mine is losing stability over 1.3, except for when i go for ram below 1333 and nb 2800+, when 1.3375 is the absolute beneficial max. currently im at 1600, sharp timings, and 2700NB... i also use 1.25, as that has been the most stable volts for that clocks... tried it over several weekends, as said
From what I have seen, most X4's have problems above 2500-2600Mhz, mine included.
that mostly counts for all variants that have locked parts, and probably the am2+ phenoms... C2 revisions of the 945,955 and 965 should all do at least 2600, and most probably 2700... sometimes, but not rarely, they also were able to go to about 2800,with some tweaking (i have one of that kind)
with the c3 revision, all deneb related silicone has its overall clocking ability improved, and can do much more similar clocking, to fullsize C2 phenoms...modern C3 Phenoms, and especially Thubans are reported to clock to about 2800-3000mhz NB, with good memclocks.
(even tho they are x6, they are still about the same architecture)
So i guess you cant say, that most have problems... i guess you just got an unlucky one
how high can you clock the memory?
Having troubles in heat department for now, though not too critical. Guess either the stock AMD HSF not keeping up with frequency, or didn't correctly applied ChillFactor III. Downvolted - 1) interesting word
; 2) lowered the VDDA volts to keep the temps lower - 2.50v. BTW : scrolled down in AI Tweaker section of BIOS & suddenly found the "nf200 chipset voltage" option : leave it be @ auto or should still play with it ? Goes from Auto to 1.20v to 1.50v max in 0.02v increments.
Soon gonna buy either pair of Scythe Ultra Kaze 3000RPM 133CFM 45dBa monstrocities, or SlipStream Jyuni 2000RPM 45/47CFM beauties (thin - 120x120x12mm). That & i'm also going for 2, maybe 3 things from SideWinderComputers (Garry is the name of guy, right ?). Even from something completely f***ed up like being fired (not quited) after 1+ year of work you gain - i get a full working month salary + another payment. Gonna convert this compensation to cooling & other good stuff.
P.S. Successfully raised the CPU's multi to 20x in BIOS today (a hour or so ago), got to the profile screen (meaning - just a click away from getting into desktop), but feared of the CPU to become an omlet on me for more than apparent reason, so reverted back to 3.9GHz. BTW : congrat me - though i don't remember exactly @ which month, but i still successfully run this 3.9GHz OC with almost no freezing (& abso-f***ing-lutely no single BSOD'ing) issues for months now & that is under "mere" stock AMD's HSF. Week or 2 from now - and i am completely serious this time - i'll post my 4.0 & later (hopefully) 4.1GHz OC on air.
P.P.S. Which of 2 progs to use on 4.0GHz OC & for how long : Prime95 or OCCT & for 1 or 2 hours ? Thanx.
Go Water, Xan! Israel is a country with a hot climate!
Whats the diff between nb with am2+ and am3? mines at 1800 would moving this up do anything?
im going to be installing my water loop tomorow it's testing atm seems good so i hope with the loop i can break my 3.6ghz wall if not i might just be running cooler.
Sure, it would yield as much as clocking the NB on AM3... on am2 tho, you wont be able to clock as high, often, depending on the boards capabilities.
try for 2400 and see if its stable, it should give you a nice boost
