3500+ newcastle at its lmit?

[imported_peterpeter]

My specs:

Neo2 plat (bios 1.8)
3500+(newcastle core)
1gb crucial ballistix pc4000 (2x512) @ 2.5-4-4-8
1xWD740 raptor
zalman cnps7000
ti-4800se(temporary video card )

So far I have only been able to overclock my cpu to 2.39ghz @

10x239 = 2390
2.5-4-4-8 @ 2.7v
vcore 1.5v
HTT=4

I cant seem to hit 2.4ghz or higher no matter what I do. I tried raising voltages, changing ram timings, lowering HTT. Am I at the limit of the newcastle core? Is this as high as i can get it?

I dont know what else could possibly be hindering me? Any ideas on what else I could try?


Could anyone else with 3500+ newcastle core post their OC's and what they did to their bios to reach that OC. That would be helpful in a million ways.


also I used to run an older bios 1.2-1.5. now that I have switched to 1.8 I get unusually HIGH cpu temps. Says its running at 53 idle and 59 load. I dont think that is true because I have really good airflow in my case(6 fans) and the Zalman cnps 7000 cu is a decent heatsink. whats going on with that?






Thanks for looking guys

Hello how do you do ,

i would recommend (if you are not) to use a mem divider and lower the timings to 3-4-4-10, then up the volts to 1.6 (1.525v at 10%), then make sure that you have spreed spectrum disabeled, use the divider and set to 100 or 133, and set RAM volts to 2.85, also drop the LDT from 4x to 3x ...

Then up the HTT/FSB untill you can not boot windows (or when it crashes on windows boot up, just make sure that you can keep getting into BIOS, before reseting the CMOS) then bench mark when you can enter into windows and lower HTT untill it is prime stable .., this wil give you max CPU speed, you can taylor the RAM specs arround the max stable CPU speed

this should help you

My 3500+ newcastle hit a wall @ 2.4ghz and no amount of vcore increase or bios tweaking would let it go further and maintain stability. That's why it's going in my in-laws computer and mine now has a venice.

 

[JohnAn2112]

My 3500+ hits a wall around 2.4 also. I can boot into Windows fine at 250x10, but Half Life 2 and WoW will crash after a while and it fails Prime95 after half an hour.

Unfortunately, OCing's a gamble, sometimes you get a good one, othertimes you don't -- having said that, my Newcastle cored 3500+ can reach 2563MHz (11 X 233MHz) with full functionalities.

im sure you can set vcore to 1.65 without problems.

 

[RichUK]

you can, use max volts and 10% this will get you 1.65, or you can use a BIOS mod and have a 18% on top of max that will get over 1.7 to 1.8, best to use water for that tho .. otherwise you might be shmoooking that NC

I see that you are using the Raptor. Make sure it's on port 3 or 4.

My newcastle 2800+ is doing 3900+, 8X325FSB. I got 2Gig of OCZ Platinum PC3200 kit and with the DFI nF3 250GB. The RAM is at divider 7:10.
The voltage by the way is 1.72V. I use the XP90.
