4000+ pushing 3Gigs on air

[Nate Finch]

Ok, so I'm not really pushing 3Gigs on air... not yet. But I want to be. I can get only slightly stable at 2880 with my 4000+. 1M Pi stable... which is to say, stable as long as I'm not actually *using* my overclocked CPU. I'm running 3.6V into my Mushkin Redlines and 1.6v into my CPU. I can't get it stable in 32M pi though... it either blue screens or just errors out. I want *stable* overclocks more than high overclocks. Anyone can take suicides... I want to know my machine isn't going to BSOD in the middle of a game of Counterstrike.

Suggestions welcome... I'll post RAM timings (2-2-2-5) and other Bios info here tomorrow.

Ive seen a couple san diegos and venices so SPI at 2.95Ghz on air check out the San Diego and Venice OC discussion threads. Far as CS:S its very sensitive about memory so lower your mem and try it.

Ive got the same CPU and @1,65v its SP1/PIFast/3Dmark stable up to 2925Mhz. Mine tops out at 2960 on air, regardless the volts i give it.

:welcome: Welcome to the forums! :welcome:

i dont know how venices and sandys go on burning in, but my newcastle went from 260x10 1.6vcore 24h prime stable to 1.56vcore 24h prime stable, saying that i have been running it in for near a year :rolleyes:

i guess a little burn in wouldnt hurt.

have you tried upping the chipset voltage?

My CPU has been running F@H at stock speeds for a couple weeks, so it's had a decent burn in period. I just got it 8 hour prime stable last night at 250x11 (1.6v on CPU, 3.3v on RAM @ 2-2-2-6). However, there seems to be something odd going on, because now it's actually *less* stable at 240x12. I can't even stay in windows for more than a minute without it blue screening. Before it would just error out of 32M Pi, and would complete 1M Pi just fine.

I've tried upping the chipset voltage all the way up to 1.7v, and it hasn't seemed to do a thing. I may try a different bios revision and see if that helps. I've heard good things about the one I'm using, but the overclocks I've seen have been on other revisions.

Gah... I can't get this thing stable even at 2805MHz (255x11). I can pump up to 1.66 volts into the CPU, 3.7 volts into the RAM, 1.7 volts into the chipset, and it's still not stable. I don't dare raise the voltage anymore... and from what I hear from everyone else, I really shouldn't have to. Anyone have any suggstions? I tried a new bios - 3/16... that helped a little bit. I tried the other RAM slots.. that helped a little bit, maybe. But still no dice on 2.8+ which is terribly frustrating, since I've seen others getting their 3700+ San Diegos up to that speed stably. :P
