AMD has produced a 3800+ which costs less than your average dual core CPU. Read more
Fluctuation of DRAM pricing over the past week has been limited, with the price change of mainstream 256 Mbit (32Mbitx8) falling less than one percentage point, and effectively tested (eTT) parts trading within a narrow range of $2.02-2.07 over the same time period. Read more
Yesterday, we asked why AMD would lower the prices on its HD 3800 line. Nvidia's 9600 GT made them do it. Read more
In an attempt to compete against Intel's plan to offer dual-core processors at competitive prices, AMD will add the Socket-AM2 Athlon 64 X2 3600+, a 2 GHz Athlon 64 X2 CPU that contains 512 kB level-two (L2) cache, in the fourth quarter of 2006, with the new part to be priced in the $139-160 range, according to sources at Taiwan motherboard makers.

Thread : Stubborn 3800 X2 won't get prime95 stable past 2350MHz

I have an Athlon 64 3800+ X2 socket 939 I am trying to overclock. My motherboard is an Asus A8N-SLI Premium. I was using the AI Overclock set at 10% for a couple years rock solid, but I recently decided to push it farther. I can get it to boot into Windows as high as 2.6GHz, but it won't run Prime95. After some playing around I discovered that core 0 is the only one that crashes in Prime95. Core 1 will run all day long without breaking a sweat. Changing RAM timings and/or speed has a limited effect, if any. Does this mean I have a flaky cpu? It's Prime95 stable at my current settings below.

What test type are you running with Prime95 that is crashing?

Prime95 spits out rounding errors during the 1hr pre-test before crunching real data. It also errors out in the stress test mode.

When you say 'stress' test for Prime I assume you mean the torture test (listed as that in my version). There are three vairants you can run: samll FFT, large FFT and blend. The first primarily stresses the cpu(s), the second mostly the cpu but some ram and the last alot more on the ram. I'm trying to understand which your running to see if we can get a hint as to a cpu or ram issue.

it's a shame 2.4Ghz is a sort of sweet spot.

OK i went back to the old ntune and checked temps while running two instances of prime95, one for each core (with affinity assigned). I let it run for about 20 minutes and temps peaked at 55c. That's a little higher than I thought it would be, but it still seems ok to me. I have a Thermaltake Blue Orb II with AS-5. As soon as I go to 240mhz fsb Prime95 errors in all three torture tests, BUT ONLY ON CORE 0.

I have been doing some more testing but I still can't get it as stable as I would like. Here is what I have it at right now.

Well world of warcraft locked up at 2450 so I dropped it down to 2400 and it ran Prime95 torture test for over 40 minutes on both cores without error. Temp never went above 59c. I think I'll just leave it there, and pray it doesn't lock up again. |

It locked up again at 2.4ghz. I took back down to 2350 and it seems to be fine now. **** that pisses me off. |

Looking at some stuff on the net, both your chip and mobo can allow for better OC's.

i'm not an overclock expert but from what i read (unless i missed the part) u havev't increased your Ram and Cpu voltages by +0.01

I probably didn't mention it, but I had the CPU voltage maxed out at 1.5v. My BIOS won't let me go any higher. The RAM is perfectly stable at 2.75v, and I have tried 2.8 as well. I may try 2.4ghz again with higher chipset voltage, but I don't expect that to work. I think there's just something wrong with core 0 on my CPU. |
