my first oc experience

[seethoe]

Hi! This is my first experience in building a PC and OC it...

Athlon64 3000+ venice (265Mhzx9=2.354GHz at 1.58v, 50degC at 100% load)
Asus A8n-SLI (HT at 3X)
Thermalright XP-90 with Themaltake smartfan
Corsair VS 512MB x2
Winfast PX6600GT
Enermax 460W PSU
Thermaltake Shark casing

I could bring HTT/FSB beyond 265 but not prime95 stable. Any advise how to bring it beyond 265?
Any suggestion on how to do the memory timing? I do not understand what is 2.5 2 2 3 6... will try to read around the forum.

bump!

anyway, i've managed to read somewhere about the meaning of 2.5-2-2-7 1T and such... mine is not at 2.5-4-3-7-1T.

Anyone has A8N-SLI board with FSB/HTT beyond 265Mhz??

What are your memory setting?

To eliminate ram as a bottleneck, set "max memory clock" to DDR200 on the DDR settings submenu of the CPU config page, and leave all your memory timings set to Auto for now. This will run ram at 1/2 the HTT speed, and see if you can push the HTT higher.

With a winchester 3200+ on this board I was able to hit 289x9. Once you find the max for your CPU then you can start working on your best ram settings.

And 265x9=2385mhz not 2354mhz

thanks. wrong calc... mmmm ... what a noob..

Ok will try your suggestion. 289 FSB, wow!

 

[seethoe]

nope, can't hit above 265FSB... either my mobo is crap or my mem is...

first off, those are pretty high temps for an xp90. what are the temps in your room? definately make sure you use a mem divider.

your mem is. sorry, but it's called "value select" for a reason. not meant for overclocking. use your ram dividers to keep that RAM as close to DDR400 as possible at default voltages and timings. only then can you isolate your cpu in your testing.

ok thanks. i use SPD on mem but the FSB can only manage up to 265Mhz before failing prime95... i've cut my CPU to 5X and HT to 3x but still the same, not able to pass 265Mhz.

oh yeah, my room temperature then was at abt 31/32deg C.

now my mem is at DDR266, 2.5-2-3-8 1T pass memtest86. My board, Asus8N-SLI (non-Deluxe) has selection for DDR400, 333, 266, 200. Failed DDR400, 333 and surprisingly 200 also but stable at DDR266.
