    Re: Overclocking nView/4000+ Brisbane (DreamCatcher v2.0)

    ok, today for posterities sake I am doing some more overclocking research. right now after a nice Easter lunch I updated my bios and put it at the following settings to start:

    Opteron 1210 with a 9 multiplier 200mhz= 1800 stock

    8 multiplier
    320 fsb
    1.375 volts on cpu
    2.1 volts on memory
    cpu/memory divider of 8 (new divider? ddr400) I previously used 7
    I jacked up the chipset voltages three notches

    CPU is 2560, with 320fsb, HTT 960, mem at 320mhz 5-5-5-15
    I slowed the memory down a bit to eliminate it as a bottleneck.
    So far so good...

    2nd round:
    CPU 2600 FSB 325 HTT 975 mem 325 no problems yet.
    Trying to see how high this FSB will go. I know some people have
    issues with their CPU handling this high a FSB, alot of it is just their
    settings however. It's hit and miss I guess...

    3rd round:
    CPU 2648 FSB 330 HTT 993.2 mem 331 Almost where my previous record was at 335
    I'm gonna start taking notes at this point, and screenshots. Once I hit my FSB limit,
    time to go for pure CPU speed...

    4th round: wow!
    CPU 2680 FSB 335 HTT 1005 mem 335 Not quite a record because last time I used tighter
    memory settings of 4-4-4-12. I can hardly believe the Gskill handled it with a 7 divider at 3ghz!

    hit a snag after setting up for 340fsb. turns out when I rebooted and checked cpu-z that the fsb was still at 335.
    I shutdown by mistake, and that's when i could not reboot. Back to 300fsb and start over lol

    After several resets, hurdles etc. I decided to stay at 9x and increase my FSB by 5mhz steps.
    CPU 2925 FSB 325 HTT 975 mem 417.9mhz at 7 divider and 5-5-5-15
    I could quite possibly go to 4-4-4-12 but I'm tired for today. I could possibly make 330 FSB but I'd like to test this for stability before proceeding. CPUZ

    I would like to toss in a tidbit here, remembering from some past experiences and also today. this MB doesn't seem to like making alot of changes in the BIOS at one time, or even large jumps in FSB etc. If you would like to experiment, go up 5mhz at a time in FSB and set your memory to a safe setting from the start, such as 5-5-5-15 and a divider of 7 or even 8 (533mhz and 400 mhz ddr respectively). I would dare say most would not make it past 320 fsb, so don't be disappointed if it doesn't.
    It's a good way to tweak your final CPU OC, but you won't gain more than about 100-300mhz this way. If your largest OC was for instance 11x290=3190, but 11.5x290=3335 or 11.5x280=3220 was not working, you can try to tweak the FSB and get something like 10x320=3200 and it would most likely work. That would put you only 10mhz higher but your FSB, Memory and HTT would be much faster. Sometimes it's not always about the highest mhz you can get from your CPU, but everything working together as a whole to net some good numbers in benchmarks or the last few fps in games. Hope this might help someone break a plateau and gain some new ground. It's a finicky MB, but awesome nonetheless!

    Cool stuff man! However I think comparing your Opty to the Brisbane is more like apples and oranges, to me anyway.

    BTW, why "hide" your hard work in this thread?? You deserve and need your own one so more people can catch it as I haven't seen a decent thread for oc'ing that series of Opteron.

    Why F@H?? Click me!

    Re: Overclocking nView/4000+ Brisbane (DreamCatcher v2.0)

    is brisbane a later core cpu? i'm not much inot what core does what but i do know the Opteron is more cream of the crop type for servers and it has 2mb of cache total. I know that Windsors were out at that time though, should be kinda the same.

    As for booting up today, wouldn't do it for anything. like I said, kinda cold buggy, but when taken up slowly it will hit some pretty good speeds and stable. Boots everytime at 2.7ghz and 300FSb. Although I'm now using a crappy 300w PS in a HTPC case, before I had a nice Antec Smartpower 500w modular PS.

    Re: Overclocking nView/4000+ Brisbane (DreamCatcher v2.0)

    Hope theGlassMan picks up on this as he is the man for the tech stuff!!

    The Brisbane is a newer core (yours is called a Santa Ana) and has half the L2 cache as yours (2 x 1000 vs 2 x 512). Also the core size is different with the Brisbane @ 65nm vs 90nm for the Santa Ana. Other than that things get a little fuzzy for me!

    You had me looking around and it appears in the long run yours will be better for gaming and the like because of thecache. I bought the Brisbane for its rep for easy oc'ing, price, and low power reguirements (low heat).

    Interestingly enough your getting more out of you 1.8 Opty 1210 than I managed with my 1.8 165! It still boils down to the luck of the draw as far as cpu fabrication, mobo, memory and mojo!

    AM2's tend to be able to run faster, up to 400MHz's.

    Re: Overclocking nView/4000+ Brisbane (DreamCatcher v2.0)

    I settled on running at 2880mhz with a bus speed of 320. My cheap Gskill memory is kicking along at 822mhz 4-4-4-12, not bad I must say so myself! I'm about 36c at idle and goes up to 48 at load, and completely stable. I am considering trying out a black edition brisbane to see what it will do, and then
    buy another matx board for my htpc, preferrably a 780g chipset.

    Re: Overclocking nView/4000+ Brisbane (DreamCatcher v2.0)

    what sort of memory do you guys run? I noticed one guy running his at 450mhz or so with looser timings , I've never run mine quite that high before but I've kept my timings at 4. I think alot of issues are revolving around the memory being too
    high. Right now I'm running 411mhz with a 7 divider.

    Re: Overclocking nView/4000+ Brisbane (DreamCatcher v2.0)

    Got one of these new 4850e cpu's (2.5ghz) and 4 gigs of ram and popped it into my nView board. Can't seem to get the bus stable over 310-315mhz. it bluescreens on me. It does however OC to around 3100mhz. If I go over that I also get bluescreens. It went to about 330mhz on the Gigabyte 780G board I purchased with it, and I ended up putting the Opty in there for an HTPC. What a nice cool combination, and the video is smoooth! I stayed at stock speed of 1.8ghz and went a tad undervolt. OC the video from 500 to 650mhz to keep temps down. I hear some folks are getting 900-950mhz! The Opty is a 103watt
    CPU so I decided not to take a chance running it 2.7ghz as it has 4 phase power. The mosfets have no cooling to them at all. I was really wanting a 9850 Phenom but alas, the 125w CPU has been know to burn up the Gigy board.
