Seems like it's going along okay... Slight graphical artifacts, I dunno

OK, I just worked for a bit on recreating my earlier overclock. Since my original work, my graphics card and memory arrived, and I switched from 2x 1gb sticks to 2x2 gb sticks, with possibly different characteristics, and also upgraded to a 4870 graphics card, which raised my in-case temperature quite a bit. With the new memory, higher clocks require raising the ddr2 voltage a bit, but still within the rated range. With the higher case temperatures, I haven't gone for 3.7 prime stable again. Here's a screenshot of a 3.6ghz OC that was stable under all the tests I ran. (Sorry for not taking the time to do longer runs, too busy using my computer for real long-term testing.)

btw my issues were solved now the only mess i make now is that it just hangs up but it doesn't go off like it used to..
Kairi_zeroblade, according to the sticker on your power supply the wattage across your four 12volt rails is 720. Take that number and divide it by 12. That will give you the total 12volt amperge (720/12=60amps).

Are you still experiencing random lockups after the new PSU purchase?

NCspecV81, wow really looking forward to these LN2 benchies. The above image alone looks sweet

Test tube, core temps look about right for full load. What type of airflow do you have in your raidmax case? What kind of graphical artifacts are you receiving? Does this occur during gaming or within Windows?

Experimental, looking good. Congrats on the new memory and video card purchase. Try adjusting your tRC so that it's 20 instead of 24. The sum of tRP and tRAS should equal the value of tRC(from what I've been told). This is of course assuming your sub-timings are 5-5-5-15.

Good luck guys

it just locks up but it never turns off now.. darn..have i made a mistake somewhere or this is just my limit??i was happy when it doesn't turn off by itself now but it now locks up on me.. i'm gonna go nuts..

ohh i see..i have seen you OC at only 1.4v with 4Ghz+ wow that must be really COLD as hell..


a silly question..is it really cold in hell..

Well, I finally got my cooling getup redone for the most part. Did not turn out quite as good as I hoped, but it was still an improvement and I think it'll pay off.

Spent the last day agonisingly close to 4.0ghz stable, and if my current test pulls through (10 minutes remaining as I post this, I'm posting from my other rig) it'll at least be 1 hr OCCT stable. Further testing would be needed of course, but seeing as I've worked it down from crashing in the first 1 minute to almost finishing, its nowhere near suicide.

I'll make sure to post benchies and whatnot if I do reach it, fingers crossed!

Edit: Error in the last 3 minutes of actual testing (7 minutes left). Argh. That said, hopefully a voltage nudge will help things out...

I have 3 80mm fans, two 120mm fans on the heatsink, one 120mm in the front, and a 140mm fan on the corsair pasu.

The artifacts are just missing graphical details in windows, though I only seemed to be getting them before and it's stable now (constant crashing from playing with OCs seems to make windows weird sometimes).

Hahaha, thanks man Even if I don't get it stable, I can always just bench with it. It's definitely stable enough for that, although I suppose it might not be accurate in some manner (it'd probably crash the os anyway if this happened).

Things are looking a bit iffy on this end however - my board/board bios is bugged, and anything above 1.61 vcore will not even post regardless of temperatures. Which is a pity, because I have a lot of headroom. It also means my computer won't boot into windows past 4.15ghz, because my temps my temps are not low enough to allow that frequency with a vcore below 1.61v.

The good news however, is that if I do get it 4.0ghz stable, it would be a 24/7 clock in winter, and with a few more cooling additions, probably 24/7 all year round (with the AC on if it it is a really hot day). In either case, there's a few more tricks I've got left to try and make it stable I believe - when its crashing, its not crashing the os, but OCCT is constantly reporting an error on the same core which must be weaker.

Well I guess I've got one more day to try and work it out, so I better get to it. Best of luck to everyone else and their oc's!
