    Default Ready to overclock and need some help

    I know I do not need to overclock now, but it has been more fun than gamming lately. How high can I go before I need to spend more Doe? I got the cooling and the memory, but having difficulty posting stable overclock. I have tried the dividers and everything. I tried 250x11-LDT/FSBX3-CPU 1.64V-DRAM 3.4V-(DRAM/FSB:5/6) 2-2-2-7 also 8 and also auto on timmings. I have tried other configurations, non have been stable. Can anyone help ?

    You'd best look for an Athlon 64 overclocking guide if no one here has a similar A64 system. My personal exprience with them is pretty limited, and much of my OCing knowledge does not apply. I don't know how well the San Diego 3700 OCs, but I'll bet it can get a lot better than a 200MHz OC on that board with that cooling. That said, what are your current temperatures?

    Aside from the CPU, using some different dividers and the latest BIOS, if you don't have it already, you should at least be able to run it at it's rated speed and timings, which you aren't ATM. There's certainly no reason to use 3.4v if you're going to leave it at that speed.

    I did some tweaking with different bios, but more questions arose. I did a little last night had to work late and be up early today. I used winflash to flash bios, Everest home edition still is reads as bios date 6/23/05, but in bios type is has the 510-2fix. Is the bios changed or is this fix just an addition to the current bios ?

    I did some benchmarking on Auqa mark 260x11 1:1 bfg 7800 gtx 525x1360. I got this




    It tops my last score by 9,000. 260x11 was not stable, but I did, I think(again not much time test) get 250x11 stable(ran OCCT test for 25 min no errors). I want to get to a core speed of 2.9 however it takes. Oh, yah, My temps beautiful. I put one of my panaflos in the intake(had to modify case, little cut and snip) temps Idle at 260x11 38c temps at load 46c I guess when your computer(3 120mm panaflos w/115cfm ea.) sounds like a boeing 747 taking off, there is enough airflow.

    hmm, get some dry ice? i find it more fun to overclock the less fortunate systems, such as the old PIIs and K6-2s, more risky, plus who cares if they break. if i broke a 3700 i'd hang myself, or just be very upset.

    What kind of voltages are you feeding that ram? ANd how about the CPU? You need to hit that ram with at least 3.3V to OC it and probably more like 3.5V to get really good clocks with it. Otherwise, back off the timings. You will need to feed that CPU 1.5-1.6V to get it over the 2.5GHz mark as well. If you have the cooling, this will be no issue. Make sure you have at least one 60MM fan on top of the ram and two would be better.

    I get over 2.7GHz stable out of my 3200+ Venice, so you should expect at least 2.6GHz stable out of that San Diego. And I would really expect to see 2.75GHz or higher stable, but no overclock is ever guaranteed. That 7800 GTX is carrying your Aquamark score. I have gotten 14.1K CPU score with my Venice. Hit that ram with some voltage and I bet you will see the same or higher.

    Read original posts.

    Anyway, fans over the RAM really are not a huge issue, as long as you have an adequately ventilated case.

    Anyway, fans over the RAM really are not a huge issue, as long as you have an adequately ventilated case.
    When using high voltages with UTT RAM it is best to have a fan blowing over top of the RAM. It even says so on Mushkins site for their Redline series.

    Active Cooling Required ----Due to the extreme speed of these modules along with the added voltages used, Mushkin requires end users to Actively cool their memory modules. Modules that are not properly cooled will/may not meet rated timings and speeds, and may become susceptible to premature failure. We generally recommend 15-25cfm of direct airflow over the ram modules which can be easily accomplished with one 60mm or 80mm low rpm fan. This will insure increased stability and lifespan of your Redline modules.

    So more or less a fan in the side of your case will suffice pending you have good airflow throughout your case as it is.

    BTW KoolDrew, took care of your account issue this morning, you were listed under the Awaiting Confirmation user group, dunno why that was. Either way, taken care of now.

    Give the ram some more juice, 3.6V or so. I agree that the fans don't need to be high flow or anything like that, just helps keep errors down when there is some aire blowing accross them. The only fan blowing accross my ram is the wash from under the XP-90 as it overlaps the ram nicely. After repeated benching, they stay cool to the touch.

    O.k. The best I can get stable so far is
    250x11 DRAM 1:1 @ Cas 2 - Ras to Cas2 - Ras Percentage 2 - Tras 6 - Trc 14
    I am running Startup at 1.450 , core at 1.425 @ Above 123% 1.3 - 1.7- and 3.4 on ram. I have voltage up to 3.7, but still errors. I have 3 120mm/115cfm panaflos, xp90, and a 80mm fan that is blowing across the ram.

    I could probably losen the timming on ram and go higher, but temps are getting up there. I am at 38c at 1.69v and 52c at load. I think I could go up a few more FSB before I would have to increase voltage again, but this is high enough without water cooling. I ran OCCT test stable for 30 minutes, I ran prime today it was stable as when I left the house(about 8hrs). I also went to bios version 510-2, It is what Redline uses, the 623-2 would get errors. I am wondering if I could lower core voltage, increase FSB and adjust timmings to get higher clock ? I believe it is my Ram that is causing the errors but I do not know where to start adjusting. Everytime I change the timming I get errors

    On adjusting the timmings. Is it just a guess on which one to back off first or is there a process or an order of priority?

    Is running prime and these other test of way of putting stress on the computer to get better performance at a lower voltage in the long run?

    I must say that the Redlines are running faster today without errors then when I first got them.

    I can not wait till F.E.A.R comes out. The demo is amazing !
