XP2500 Barton Overclock Failure
Hi,
I have an XP2500 Barton core CPU and I would like to try and overclock it to 2200Mhz. I have done some initial tests and I can't seem to overclock the CPU at all. Increasing the FSB by only a few MHz causes windows to fail to boot. An attempt to clock the FSB to 200MHz results in windows stating that it can't load several files from the hard disk during the initial stages of boot up. I realise that using the Via KT600 chipset means that I can not lock the PCI bus frequency. When I bought the CPU a few months ago I fitted the heatsink incorrectly which caused several unexpected over-temp shutdowns. I eventually realised and corrected the problem. The system is very stable at the XP2500 speed but could the inability to clock to XP3200 speed be a result of damage to the CPU caused by the overheating or is it more likely that another component is causing the problem. NB: During the above tests the clock multiplier is set to 11x and the CPU voltage is set as standard for the XP2500. My set-up is as follows: XP2500 Barton, AMD supplied HSF; Asus A7V600-X; 512MB Crucial PC3200 RAM; Gainward FX5200 GFX. Cheers, Simon Bale. |

I don't know if you can but you need to raise the core voltage. I can't get my 2500 much over it's rated speed at the cpu's default voltages. Right now I have my machine set at 1.8V core, 210 fsb and 11 multi it's rock stable no problems at all. I had Kingston ValueRam in it and it wouldn't get over 180 fsb like that. With HyperX it went straight to 200 with no problem. Right now it'll run Prime 95 all day with no problem. You will need a better HSF if you plan on pushing it up though the retail HSF will not keep it cool no matter how much air you pump through your case. Right now my set up is an Epox 8RDA+ board Rev 1.1, 768 mb Kingston HyperX DDR400 in dual channel, Barton 2500+ and a free Antec Super Server case courtesy of the clueless idiots and Newegg.com. Newegg's a damn good company but they've got some real dumbf*cks working there. Roger |

Tadaa... try raising the core voltage.......
Thomas ....and disable spread spectrum modulated while you're at it... I've gotten the 2500 to run at 400fsb with the kt600 chipset in the MSI KT6V-LSR with no problems at all...if you don't count using a 60mm-80mm fan adapter and a soltek 80mm fan on the retail heatsink to get some serious air running around in there a problem...

You've got 3200 speed ram, so that's OK. Your m/b whould not be a problem,
and I doubt very much if there's anything wrong with the Barton itself. As others have said here, vcore should be up to wherever it takes to become error free on Prime95. For me , that was 1.75 I'd remove the hs/f just to double check proper contact and paste application.You don't say in your posts what your CPU external and internal temps are running at stock speed. Judging from the stability at even mild o/c rates, they sound high. Try AIDA32 for monitoring core/external after heavy load. Are you using the stock AMD cooler and do you have case fans installed? |

Replace the stock HSF with something decent ($8 TR2-M1 should be fine) Raise vcore to 1.85v Raise ram voltage by .1 or .2 Slow down ram timings, try CL3. Set FSB to 200 and give it a try. Make sure it's using a 6 divider at 200MHz. If that works, adjust accordingly. -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) http://mysite.verizon.net/res0exft/cpu.htm |

I've tried the steps suggested previously and the processor will boot into
windows but crashes almost immediately after a login. Does this indicate that I have an XP3200 which has been speed binned or is it likely that I caused damage when I had an incorrectly fitted heatsink. Are there any other steps that I could try to overclock the device? Best Regards, Simon Bale. "Wes Newell" wrote in message newsan.2004.03.20.22.47.19.423484@TAKEOUTverizon .net...

You've never said what CPU temps you're getting, or type of CPU cooling you're using or whether you have any effective case ventilation. These symptoms sound exactly like CPU core overheating. |

My CPU idle temp is 43C and rises to 54C running the Prim95 torture test. I
have 3x80mm case fans installed and the stock AMD HSF. Cheers, Simon. "Augustus" wrote in message news:2op7c.231726$A12.101668@edtnps84... "Simon J. Bale" wrote in message ...

Are there any other steps that I could try to overclock the device? I don't know much about that board and a quick check for reviews didn't turn up much either but there are three user feedbacks on Newegg (yours IS the Asus A7V600-X mentioned below, right?) and one of them had a lot of problems till they downloaded "better drivers," as they put it, from --VIA-- (not Asus). They also settled for a 1.94 MHz at 180MHz FSB overclock on their XP2500+, which makes me wonder. http://www.newegg.com/app/ViewProduc...pa=0§ion=3 Best Regards, Simon Bale.
